What Land Rover windscreen features mean

Tap a feature to see what it is, how to spot it on your car, and how it affects glass replacement. We confirm the exact match for your vehicle when you book.

• Vin Notch185

  1994–2026

  A printed VIN reference box along the bottom edge of your windscreen helps identify your vehicle's chassis number at a glance.

  What it means

  A VIN (Vehicle Identification Number) notch is a small printed or etched box positioned along the lower edge of the windscreen that displays your vehicle's chassis number. This reference marking is a manufacturing and administrative feature, allowing quick visual identification of the vehicle without needing to consult documents. It's particularly useful for service records, insurance claims, and vehicle registration purposes. The notch itself doesn't affect the structural integrity or safety performance of the glass.

  How to tell

  Look along the bottom edge of your windscreen — typically in one of the lower corners — for a small rectangular box containing printed digits or characters. If you're uncertain, check your vehicle's service handbook or ask your dealership or service centre to confirm whether your model includes this feature.

  Replacement impact

  When your windscreen is replaced, the new glass will retain the VIN notch printed or etched by the manufacturer. This is a standard feature on replacement windscreens for compatible vehicles and requires no additional work or adjustment. The notch does not affect glass fitting, cure time, or any post-replacement calibration procedures.

• Rain Sensor168

  2002–2026No calibration after replacement

  Your wipers automatically activate when rain falls on the windscreen.

  What it means

  A rain sensor is a device mounted on or behind the windscreen that detects moisture and triggers the wiper system automatically. The sensor uses infrared light to measure water droplets on the glass surface and signals the vehicle's electrical system to engage the wipers without driver input. This feature improves safety in sudden downpours and reduces driver workload in variable weather conditions.

  How to tell

  Check your windscreen for a small sensor unit, usually mounted near the top centre behind the glass or at the base of the mirror. Look for a small dark component or lens. If your vehicle has automatic wipers that activate without you toggling the stalk, you have a rain sensor. Ask your dealer or service centre to confirm; they can check your vehicle records or wiper module settings.

  Replacement impact

  Rain sensors are non-structural elements and do not require recalibration after windscreen replacement. The sensor bracket or mounting may need careful removal and reinstallation to ensure it sits correctly behind the new glass. If the sensor itself is damaged during removal, a replacement unit may be needed. Your fitter will confirm the condition and refit or replace the sensor as part of the standard replacement procedure.

• Acoustic (Noise reduction)157

  2002–2026

  Acoustic glass reduces cabin noise for a quieter, more comfortable ride.

  What it means

  Acoustic windscreen glass is laminated with a special acoustic interlayer that absorbs and dampens sound vibrations. It reduces exterior noise—from traffic, wind, and road surface—before it enters the passenger compartment. This makes the cabin noticeably quieter and creates a more peaceful driving experience. It's a comfort feature, not a safety one; standard laminated windscreens already meet impact safety requirements.

  How to tell

  Check your windscreen for an ear symbol, the word 'Acoustic', a capital 'A', or the term 'SoundScreen' printed in one of the four corners. These markings indicate acoustic-grade glass. You can also ask your vehicle's dealership or service centre whether your model came fitted with acoustic glass—it's often a factory option on comfort or premium trims.

  Replacement impact

  Acoustic glass is always laminated and bonds to the frame like any standard windscreen, so replacement follows the normal bonded-glass procedure. No specialist calibration is required. The replacement technician will fit it using standard adhesive and sealant. Cure time and drive-away restrictions are identical to standard laminated windscreens. Acoustic glass is widely available as an aftermarket OE-equivalent option.

• Green134

  1970–2026

  Green tint reduces glare and improves visual comfort by filtering certain light wavelengths.

  What it means

  Green tint is a light-filtering coating applied to the glass during manufacture. It absorbs and reduces transmission of certain wavelengths of light, primarily to cut glare from sunlight and reflections. The tint is subtle — often barely visible to the naked eye — but measurably improves visual comfort during prolonged driving, particularly in bright conditions. It's a factory specification chosen by the vehicle manufacturer to balance daylight comfort with interior visibility and aesthetic consistency across all glass in the vehicle.

  How to tell

  The easiest way to check is to roll your side window halfway down and hold a piece of white paper behind it. Look carefully for a tint cast — green tint will appear as a subtle green hue compared to clear glass. Your windscreen will have the same tint as your side windows. You can also ask your vehicle's dealership or service centre — they'll have the original specification on file.

  Replacement impact

  Green-tinted replacement glass must match the original tint specification to maintain visual consistency across all windows and preserve the vehicle's interior aesthetics. Aftermarket OE-equivalent (OEE) green-tinted glass is widely available, though some vehicles may require original equipment (OEM) dealership glass if the tint specification is proprietary. Tint does not affect calibration, cure time, or installation procedure — it's a cosmetic and functional specification only.

• Heated Windscreen130

  1970–2026

  Heated windscreens use embedded wires to quickly clear ice and condensation in cold weather.

  What it means

  A heated windscreen is integrated with a fine mesh of electrical wires embedded within the glass itself. When activated, these wires generate heat to warm the windscreen surface, helping to rapidly clear frost, ice, and condensation during cold or damp conditions. This feature improves visibility and safety in winter driving and reduces reliance on engine heat and demister air, which can be slower on very cold mornings.

  How to tell

  Check your vehicle's handbook or contact your dealership service centre — they can confirm whether your model includes this feature. Look for a dashboard symbol (usually a windscreen icon with heat waves) when you activate the function, or check your infotainment settings for a heating or climate option linked to the windscreen. Some vehicles have a dedicated button on the stalk or console.

  Replacement impact

  Heated windscreens require replacement glass to be of the correct heated specification — standard unheated glass cannot be fitted. The replacement glass must be sourced to match your vehicle's exact heated-wire configuration. Installation is straightforward, though the technician will confirm the heating element is functioning correctly after fitting. No calibration is required for this feature.

• Camera77

  2012–2026Calibration varies by vehicle

  A camera mounted near the rear-view mirror monitors the road ahead for lane-keep and traffic-sign features.

  What it means

  A forward-facing camera positioned in the windscreen header area (typically mounted on or near the rear-view mirror bracket) captures video of the road ahead. This camera feeds data to driver-assistance systems such as lane-departure warning, lane-keep assist, autonomous emergency braking, and traffic-sign recognition. The camera is a core component of modern ADAS (Advanced Driver Assistance Systems) and requires precise alignment after windscreen replacement to ensure these safety features function correctly.

  How to tell

  Look for a small dark triangular or lens-shaped component mounted in the black plastic trim area above the windscreen, typically centred near the rear-view mirror or slightly to one side. Your vehicle's handbook or infotainment menu may reference 'Lane Assist', 'Traffic Sign Recognition', or 'Autonomous Emergency Braking'. Ask your dealer or service centre directly if your car is equipped with a forward-facing camera system.

  Replacement impact

  Windscreen replacement on camera-equipped vehicles requires calibration of the camera system after the new glass is fitted. The exact calibration procedure—whether static (using a target board in a controlled environment) or dynamic (road-based)—varies by vehicle make, model, and year. We confirm the precise calibration requirement when we look up your specific vehicle. Calibration ensures lane-keep, sign recognition, and emergency-braking systems function safely. This may extend the fitting schedule and may necessitate workshop-based fitting rather than mobile attendance.

• Bracket For Safety Features75

  2012–2026Calibration varies by vehicle

  The moulded trim that surrounds your camera and sensor cluster at the top of the windscreen, typically transferred or supplied with replacement glass.

  What it means

  A bracket for safety features is the moulded plastic or composite shroud that sits at the top of the windscreen, framing and protecting the camera and sensor cluster mounted behind the rear-view mirror. This trim cover houses forward-facing driver-assistance cameras and sensors — equipment that monitors the road ahead for lane-keeping, collision warning, adaptive cruise control, and similar safety functions. The bracket itself is part of the vehicle's structural frame, but the trim cover you see is what protects and aesthetically integrates the technology into the windscreen area.

  How to tell

  Look at the top centre of your windscreen, just above or around the rear-view mirror. If you see a dark moulded shroud or trim panel — often rectangular or tapered — with a visible lens or sensor window, your vehicle has a bracket for safety features. Your service history or handbook will list any ADAS (Advanced Driver Assistance System) technologies fitted. Ask your dealer or service centre if your vehicle has forward-facing cameras or sensors; if it does, you have a bracket for safety features.

  Replacement impact

  On windscreen replacement, the trim cover is typically transferred from your old glass to the new one, or supplied pre-integrated with the replacement depending on the variant. This means minimal disruption to your safety system during the swap. However, if the bracket requires recalibration after glass replacement — which depends on your specific vehicle and camera type — the job may require static calibration (using a target board) or dynamic calibration (a road drive). We confirm the exact calibration procedure when we look up your vehicle.

• Defogging Detector74

  2004–2026

  A defogging detector automatically clears condensation from your windscreen, improving visibility in damp conditions.

  What it means

  A defogging detector is a sensor that monitors moisture levels on the windscreen and triggers the demister system automatically when condensation builds up. It improves driver visibility and safety in damp or cold weather by preventing manual intervention. The sensor typically sits near the rear-view mirror, positioned to sense moisture accumulation on the glass surface.

  How to tell

  Check your vehicle's handbook or ask your dealer's service centre whether your model includes an automatic defogging or moisture-sensing demister. Look near the rear-view mirror for a small sensor unit. Some vehicles display an indicator light or message on the dashboard when the system is active.

  Replacement impact

  The defogging detector does not affect windscreen replacement or require recalibration after fitting. The sensor itself remains in place and continues to function once the new windscreen is installed. No additional calibration, cure time, or specialist procedures are needed.

• Clear67

  1983–2026Calibration varies by vehicle

  Clear windscreen glass has no tint; most cars have a slight tint as standard.

  What it means

  A clear windscreen contains no added tint layer. Most modern windscreens incorporate a subtle tint (typically blue, green, grey or bronze) as standard to reduce glare, provide UV protection, and improve cabin comfort. A genuinely clear windscreen is the absence of this tint. Clear glass is less common than tinted variants and is sometimes specified for aesthetic or operational reasons, though the tint difference is usually imperceptible to the naked eye.

  How to tell

  Lower your side window halfway and hold a white piece of paper behind it. If you see a noticeable colour cast (blue, green, grey or bronze) in the side glass, your windscreen has the same tint. You can also ask your vehicle's dealership or service centre to confirm the windscreen specification in your service records.

  Replacement impact

  Clear windscreen replacement uses the same installation process as any other windscreen. No special calibration or extended cure time applies. Sourcing is straightforward — clear glass is widely available as an aftermarket replacement. Installation time and drive-away restrictions follow standard windscreen replacement timings. If your vehicle has ADAS features (forward-facing camera or radar), calibration may be required after replacement depending on your specific vehicle; we confirm this when we look up your car details.

• Coating65

  2003–2026

  Coated windscreens have a blue or purple tint and protect your car from UV rays and heat.

  What it means

  A coated windscreen has a special protective layer applied to the glass that appears as a blue or purple tint and often reflects a silvery-blue colour in bright sunlight. This coating is designed to reduce the amount of ultraviolet (UV) radiation and solar heat that enters the vehicle, helping to keep the interior cooler and protecting upholstery and dashboard components from UV damage and fading. The coating is integral to the glass and doesn't require any special maintenance from you.

  How to tell

  Look at your windscreen in bright daylight — a coated windscreen will show a distinct blue or purple tint and a silvery-blue reflection when the sun hits it directly. Check your vehicle's service booklet or window sticker (usually on the driver's door jamb), which may list the glass specification. Alternatively, ask your dealership or service centre to confirm whether your windscreen carries a UV or heat-rejection coating.

  Replacement impact

  When replacing a coated windscreen, the replacement glass must match the original specification — including the coating type and tint level — to maintain the same UV and heat protection and to preserve the vehicle's interior aesthetics. Original-equipment or equivalent aftermarket coated glass is sourced to specification. The coating is applied during glass manufacture; no post-fit treatment is required. Fitting and cure times are unaffected by the presence of the coating.

• HUD - Head Up Display54

  2012–2026No calibration after replacement

  A Head-Up Display projects your speed, navigation cues and key alerts onto the windscreen so you can read them without looking down.

  What it means

  A Head-Up Display (HUD) projects driving information — speed, navigation cues, ADAS alerts — onto the windscreen in your line of sight, so you can read it without taking your eyes off the road. The projector is mounted in the dashboard and shines the image upwards onto a special HUD-compatible windscreen that uses a wedge-shaped laminate to prevent a ghost image. Common on premium and sports models, increasingly standard on mid-range cars from the 2020s onwards.

  How to tell

  Check your vehicle's specification sheet or handbook under 'display features' or 'HUD'. Look for a small projector unit mounted on the dashboard, typically below the steering wheel or in the instrument cluster area. When you start the vehicle, a bright image should appear on the lower windscreen area. Your dealer's service centre can confirm whether your specific model and trim level includes a HUD.

  Replacement impact

  Your replacement windscreen needs to be HUD-compatible — built with the correct wedge laminate so the projected image stays sharp and double-free. Once the HUD-compatible glass is fitted, the projector itself typically doesn't need recalibration: image position is user-adjustable via your dashboard controls. We confirm your vehicle uses the HUD-compatible windscreen variant when ordering, so the replacement matches the original.

• Solar Control45

  1994–2026

  Solar control glass absorbs infrared rays to reduce heat and improve cabin comfort.

  What it means

  Solar control is a coating applied to the windscreen that absorbs the sun's infrared radiation rather than allowing it to pass through into the cabin. This reduces solar heat gain, helping to keep the interior cooler and more comfortable, particularly in warm weather or direct sunlight. The coating is transparent to visible light, so it doesn't darken the windscreen or affect visibility. It's a passive thermal management feature that works continuously whenever the sun is shining on the glass.

  How to tell

  Check your vehicle's specification sheet or contact your dealership service centre to confirm whether solar control glass is fitted. Some manufacturers list it as 'solar control windscreen', 'heat-reflective glass', or 'thermal management glass'. It's a factory-fitted feature and won't be visibly obvious from outside the car — the coating is integral to the glass itself.

  Replacement impact

  Solar control glass is a factory-fitted specification. When replacing the windscreen, a solar control variant must be sourced to match the original. This is a standard glass type with no special fitting implications or calibration requirements. Cure and drive-away times follow normal windscreen bonding procedures. Confirm with your fitter that the replacement glass includes solar control to maintain the original thermal performance.

• Stereo Camera33

  2013–2026Calibration varies by vehicle

  Dual cameras mounted near the rear-view mirror provide advanced driver-assistance features like collision avoidance and lane-keeping.

  What it means

  A stereo camera is a pair of cameras mounted in the upper windscreen area, typically embedded in or near the rear-view mirror housing. These cameras work together to capture depth information, allowing the vehicle's safety and driver-assistance systems to detect obstacles, measure distances, recognise lane markings, and monitor road signs. Stereo cameras are central to modern collision-avoidance, adaptive cruise control, lane-keeping assistance, and pedestrian-detection systems. Unlike single cameras, the dual-lens setup provides three-dimensional awareness, enabling more accurate decision-making by the vehicle's control modules.

  How to tell

  Look in the dark area of the windscreen near the top, directly above or slightly offset from the rear-view mirror. You will see two small lens housings — typically circular or oval — separated by a small gap. Some vehicles display a camera symbol on the dashboard or in the instrument cluster when the system is active. Your vehicle's handbook or service centre can confirm the presence and type of camera system if you're uncertain.

  Replacement impact

  Stereo cameras are bracket-mounted to the windscreen frame and require careful removal and reinstallation during replacement. The camera alignment is critical for safe operation — even small deviations can impair collision detection and lane-keeping accuracy. After windscreen replacement, your vehicle's camera system may require static or dynamic calibration depending on the specific make and model. We confirm the exact calibration procedure and schedule when we look up your vehicle. Calibration ensures the dual lenses are precisely aligned and the depth-sensing algorithms function correctly.

• Dynamic Camera Calibration Process28

  2013–2026Calibration varies by vehicle

  Dynamic calibration uses road driving to recalibrate your camera after windscreen replacement.

  What it means

  Dynamic camera calibration is a procedure in which a technician drives the vehicle on marked roads at set speeds after the windscreen has been fitted and the adhesive has cured. During this drive, the forward-facing camera relearns its reference points — lane markings, road signs, road edges and surrounding traffic patterns — so it can resume accurate operation of camera-dependent safety and driver-assistance systems. This recalibration is necessary because any windscreen replacement, even with precision fitting, can introduce small shifts in the camera's optical alignment relative to the road.

  How to tell

  Check your vehicle's handbook or contact your dealer to confirm whether your car has a forward-facing camera system. If it does, ask the dealer whether your specific model requires dynamic (road-drive) or static (target-board) calibration after windscreen replacement. You can also ask your fitter — they will establish this when they look up your vehicle's specification.

  Replacement impact

  After your windscreen is fitted and the bonding has cured, a technician will drive the vehicle on marked roads at controlled speeds to allow the camera to relearn its environment. This extends the overall job duration beyond the glass-fitting time alone. Depending on your vehicle, calibration may be performed during the same visit or scheduled separately. We confirm the exact procedure and location (mobile or workshop) when we look up your specific vehicle.

• Light Sensor24

  2004–2026

  Light sensors automatically turn your headlights on at dusk or in tunnels; the replacement windscreen must include the sensor bracket.

  What it means

  A light sensor is a small optical detector mounted on the windscreen or dashboard that monitors ambient light levels. When light drops below a threshold—at dusk or when entering a tunnel—it triggers your headlights to switch on automatically. This removes the need to manually operate the lights and improves safety by ensuring visibility when conditions darken suddenly. The sensor is typically mounted behind the windscreen's top edge or integrated into the interior mirror housing, where it has an unobstructed view of the sky.

  How to tell

  Check your vehicle's handbook or ask your dealer whether your car has automatic headlight control or 'auto lights' as a feature. If equipped, you'll see a symbol on the stalk or dashboard dial marked with a light-bulb icon or 'AUTO' setting. When you select this mode and the ambient light dims, the headlights activate without manual input. Not all cars have this feature; it's typically found on newer or higher-specification models.

  Replacement impact

  When replacing a windscreen on a vehicle with a light sensor, the replacement glass must include the correct sensor bracket or mounting point to preserve the auto-headlight function. The sensor itself does not require software calibration—it relies on physical positioning behind the windscreen's upper trim or within the mirror assembly. Ensuring the bracket is correctly installed during the fit is essential; if omitted, the auto-light feature will fail and cannot be restored without additional parts and labour.

• Heat Absorbing PVB14

  2016–2026

  Heat-absorbing PVB interlayer reduces solar gain and cabin temperature on warm days—but must match your original spec.

  What it means

  Heat-absorbing PVB is a specially formulated interlayer sandwiched between the glass plies in your windscreen. It absorbs a portion of the sun's infrared radiation before it enters the cabin, reducing solar heat gain on warm days. This keeps the interior cooler and reduces air-conditioning workload. The feature is built into the glass during manufacture and cannot be added or removed after production. If your vehicle left the factory with this interlayer, any replacement windscreen must carry the same PVB specification to maintain the original thermal performance.

  How to tell

  Check your vehicle's specification sheet or handbook—heat-absorbing PVB is listed under windscreen or glass specification. You can also ask your dealership service centre or provide us with your vehicle registration; we'll confirm whether your car came with this feature as standard or as an option.

  Replacement impact

  Replacement windscreens with heat-absorbing PVB must be sourced to the exact OE specification—aftermarket alternatives with standard PVB will not deliver the same solar-control performance. We ensure the correct spec is ordered before the fit. No calibration is required. Installation and cure procedures are identical to standard windscreen replacement; the interlayer is integral to the glass and requires no additional treatment.

• Heated Wiper Rest Area11

  2002–2026

  Heating elements embedded in the glass melt ice from your wipers and the bottom of your windscreen.

  What it means

  A heated wiper rest area uses electric heating elements embedded into the windscreen in the area where your wipers park when not in use. These elements warm the glass to prevent ice and frost from bonding to the wiper blades and the lower windscreen edge during cold weather. This reduces the effort needed to clear ice in the morning and helps protect your wipers from damage caused by frozen adhesion to the glass.

  How to tell

  Check your windscreen's lower edge where the wipers rest — you may see faint heating lines or elements visible in the glass. Your handbook or service history will confirm the feature. You can also ask your dealer or service centre whether your vehicle is equipped with a heated wiper rest area.

  Replacement impact

  When replacing a windscreen with a heated wiper rest area, the replacement glass must include the heating elements. Aftermarket and OE glazing suppliers offer this feature, but availability varies by vehicle. The heating system does not require calibration after replacement, though the technician will ensure the heating element connections are properly restored during installation.

• Green Sun Strip10

  2002–2026

  A green-tinted band at the windscreen's top edge that reduces glare from sunlight above.

  What it means

  A green sun strip is a graduated tint band integrated into the windscreen's laminate at the upper edge. It filters intense sunlight and glare from above — particularly useful on motorways and in bright conditions — whilst maintaining clarity through the main viewing area below. The tint is permanent, fused into the laminate layer during manufacture, and cannot be applied or removed afterwards. Sun strips are a windscreen-only feature because they must be built into the laminate during production; side and rear glass cannot carry them as they are typically toughened rather than laminated.

  How to tell

  Look at the top edge of your windscreen from the inside. A sun strip appears as a distinct green-tinted gradient band that fades from darker at the very top to clear below. It is visible whether the car is parked or moving. You can also check your vehicle's specification sheet or ask your dealership or current service centre to confirm whether your windscreen includes a sun strip.

  Replacement impact

  The replacement windscreen must be the green sun strip variant to match your original. This is not a post-fit addition; it must be ordered as part of the glass itself. Availability is usually straightforward for current and recent models from major manufacturers, though older or less common variants may require a longer lead time. The sun strip does not affect calibration requirements or cure time — it is simply a laminate feature and does not complicate the fitting process.

• Mono Camera5

  2015–2019Calibration varies by vehicle

  A single camera mounted near the rear-view mirror that helps with lane-keeping and collision avoidance.

  What it means

  A mono camera is a single-lens camera positioned behind the windscreen, typically in the upper centre area near the rear-view mirror. It captures the road ahead and uses computer vision to detect lane markings, vehicles, and road hazards. The camera feeds data to driver-assistance systems such as lane-keeping assist, lane-departure warning, and forward-collision warning. It forms the visual foundation of these safety features, allowing the vehicle to monitor road position and surrounding traffic automatically.

  How to tell

  Look in the black trim area above the windscreen, centred behind the rear-view mirror — you will see a small triangular lens assembly or dark lens cover. Check your vehicle handbook or ask your dealer's service department to confirm your model has lane-assistance or collision-warning features; vehicles with these systems almost always have a mono camera. Dashboard warning symbols related to lane or collision systems also indicate the presence of this camera.

  Replacement impact

  When the windscreen is replaced, the camera bracket and lens assembly must be removed and carefully repositioned on the new glass. The camera may require calibration after fitting to ensure accurate road detection and lane recognition. Calibration needs vary by vehicle — we confirm the exact procedure when we look up your specific vehicle. The job may take longer than a standard windscreen replacement, and workshop facilities may be required if calibration demands a controlled environment.

• Heat Reflective1

  2019–2023

  Heat-reflective tinting reduces solar gain and cabin temperature, often visible as a darker shade near the windscreen's top edge.

  What it means

  Heat-reflective tinting is a specially formulated layer applied to the windscreen—usually concentrated in the upper band near the black dots (the frit)—designed to reflect solar radiation and reduce heat buildup inside the vehicle. This helps maintain cabin comfort, reduces air-conditioning load, and can protect interior materials from UV damage. The tint is typically darker or noticeably different in colour than the front side windows, which remain clear or lightly tinted.

  How to tell

  Look at your windscreen from inside the vehicle and compare the tint colour to your front side windows. Heat-reflective windscreens often have a visibly darker or warmer tone, especially in the upper portion within 2 cm of the black-dot edge (the frit). You can also check your vehicle's specification sheet or ask your dealership service centre whether your model includes heat-reflective glazing.

  Replacement impact

  Replacement windscreens with heat-reflective tinting must be sourced to the exact specification of your original glass—aftermarket equivalents are available but must match the tint density and reflective properties. The tinting is integral to the glass itself and cannot be applied afterwards. No calibration is required. The windscreen is bonded in place and cure time applies as standard.
