Price variation across the four active variants depends mainly on trim-level differences in optional features — acoustic glass, heated windscreen, and the presence of a sun strip all affect final cost. Earlier 2003–2004 models without these premium glass options are typically more affordable than higher-specification later variants.

The Lexus RX 300 does not feature camera-based driver assistance systems, so no ADAS calibration is required after windscreen replacement. Mobile fitting at your home or workplace is the standard option — your technician arrives with the glass and completes the job on-site in a single visit.
You can always choose a workshop appointment if you prefer, perhaps for convenience or weather reasons, but it's not necessary for this model.

Green tint reduces glare and improves visual comfort by filtering certain light wavelengths.
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.
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.
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.
Your wipers automatically activate when rain falls on the windscreen.
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.
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.
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.
A printed VIN reference box along the bottom edge of your windscreen helps identify your vehicle's chassis number at a glance.
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.
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.
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.
Heating elements embedded in the glass melt ice from your wipers and the bottom of your windscreen.
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.
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.
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.
Acoustic glass reduces cabin noise for a quieter, more comfortable ride.
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.
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.
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.
Heated windscreens use embedded wires to quickly clear ice and condensation in cold weather.
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.
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.
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.
A blue-tinted gradient band across the top of your windscreen that reduces glare without affecting your view of the road.
A blue sun strip is a tinted gradient band built into the upper edge of your windscreen's laminate layer. It reduces glare from sunlight reflecting off the road and bonnet without darkening your main field of vision. The tint is created during manufacture as part of the glass laminate itself — it cannot be added or removed later. Sun strips are a windscreen-only feature; rear and side windows cannot carry this effect because they use tempered rather than laminated glass.
Look at the top of your windscreen from inside the car — you'll see a distinct blue-tinted band running horizontally across the upper portion. Check your vehicle's specification sheet or ask your dealership service centre whether your windscreen is listed as a 'blue sun strip' or 'tinted sun strip' variant. Your invoice or parts manual will confirm it.
When replacing a windscreen with a blue sun strip, the replacement must be the sun-strip variant — a standard plain windscreen will not replicate the tinted band. Your replacement glass is sourced as an exact match to your original specification. There are no additional calibration or cure implications beyond a standard windscreen replacement. Fitting and drive-away times remain unchanged.
A green-tinted band at the windscreen's top edge that reduces glare from sunlight above.
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.
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.
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.
The Lexus RX 300 was in production from 2003 to 2006, establishing itself as one of Japan's earliest mainstream luxury SUVs. Its windscreen comes fitted as standard with green-tinted laminated glass, a rain sensor for automatic wiper activation, and a VIN notch along the bottom edge.
Most variants also feature a heated wiper rest area to assist with defrosting. Some higher-specification models include acoustic glass for noise reduction, or a heated windscreen element built into the laminate. A small number of variants carry a subtle green sun strip at the top to reduce glare from above.
Because the RX 300 predates widespread camera-based driver assistance systems, windscreen replacement is straightforward — no ADAS calibration is required, and mobile fitting at your address is the standard approach.
