3. Product Overview
This heated side mirror glass is designed for specific Lexus models and features:
- Special Car Compatibility: Designed for Lexus RX350, NX300h, RX450h, RX NX, and NX200t models produced between 2015 and 2022. It accurately matches the size and shape of the original car mirror for seamless integration.
- Heating Defrosting Function: A built-in heating element quickly removes frost and fog from the mirror surface in cold weather, ensuring a clear view. The heating function is controlled via the vehicle's internal switch.
- Blind Spot Warning System: An integrated system monitors blind areas to the rear and side of the vehicle using sensors. A warning signal is activated when a vehicle enters the blind zone, helping to prevent collision accidents during lane changes.
- HD Reflective and Anti-Glare Design: High-definition reflective materials provide a clear rear view, even at night or in low light. The anti-glare function reduces interference from the headlights of trailing vehicles, improving night driving safety.

7. Operating Instructions
7.1. Heated Mirror Function
The heating function of the side mirrors is typically activated automatically with the rear defroster or by a dedicated switch within your vehicle. Consult your Lexus owner's manual for specific instructions on activating the heated mirrors. Once activated, the built-in heating element will quickly clear frost, ice, or fog from the mirror surface.
7.2. Blind Spot Warning (BSW) System
The integrated BSW system continuously monitors the blind spots of your vehicle. When another vehicle enters your blind spot, a visual indicator (usually an illuminated icon) will appear on the mirror glass. If you activate your turn signal while a vehicle is detected in the blind spot, an additional audible or visual alert may be triggered, depending on your vehicle's specific system. Always check your surroundings visually before changing lanes, even with the BSW system active.

8. Maintenance
- Cleaning: Clean the mirror surface regularly with a soft cloth and a mild glass cleaner. Avoid abrasive cleaners or harsh chemicals that could damage the reflective coating or the blind spot warning indicator.
- Inspection: Periodically inspect the mirror glass for cracks, chips, or loose connections. Address any issues promptly to maintain optimal performance and safety.
- Wiring: Ensure all wiring connections remain secure and free from corrosion.
9. Troubleshooting
9.1. Mirror Heating Not Working
- Check Vehicle Controls: Ensure the heated mirror function (often linked to the rear defroster) is activated in your vehicle.
- Inspect Wiring: Verify that the electrical connections to the mirror's heating element are secure and free from damage or corrosion.
- Check Fuse: Consult your vehicle's owner's manual to locate and check the fuse for the heated mirrors. Replace if blown.
9.2. Blind Spot Warning Not Activating
- Check Vehicle Settings: Ensure the BSW system is enabled in your vehicle's settings.
- Inspect Sensors: The BSW system relies on external sensors (usually located in the rear bumper). Ensure these sensors are clean and unobstructed.
- Wiring Connections: Verify that the wiring for the BSW indicator on the mirror is correctly connected.
9.3. Distorted or Unclear Reflection
- Clean Mirror: Clean the mirror surface thoroughly with a suitable glass cleaner.
- Inspect for Damage: Check for any physical damage to the mirror glass itself.
10. User Tips
- Regular Cleaning: Keep your mirrors clean, especially the area around the blind spot indicator, to ensure optimal visibility and system performance.
- Winter Preparation: In snowy or icy conditions, gently clear any accumulation from the mirror surface before activating the heating function to prevent strain on the heating element.
- Double Check: Always perform a visual head check before changing lanes, even when the Blind Spot Warning system indicates a clear path. Electronic systems are aids, not replacements for attentive driving.
