What should be done if the automatic high beams aren’t working on a 2018 Toyota RAV4?

Check the Automatic High Beam System Settings

• Start by ensuring that the automatic high beam system is turned on. You can do this through the vehicle's settings menu, usually found in the instrument panel or multimedia display.

Verify the Light Sensor

• Ensure nothing is obstructing the camera or sensors, typically located near the rearview mirror. Dirt, debris, or stickers can impede the system's ability to function properly.

Inspect the Windshield

• Check for any cracks or chips in the windshield that might obstruct the sensor's view.

Update Software

• Sometimes a software update is required to ensure all vehicle systems function correctly. Visit a Toyota dealership to see if there are any available updates for your RAV4's software.

Check the Lighting System Components

• Examine the headlight bulbs and fixtures to ensure they are in good working condition. Replace any burnt-out or damaged bulbs.

Scan for Error Codes

• Use an OBD-II scanner to check for any diagnostic trouble codes (DTCs) that might indicate a specific issue with the automatic high beam system.

Consult the Owner’s Manual

• Refer to the owner’s manual for your 2018 Toyota RAV4. Look for troubleshooting tips specifically for the automatic high beam system.

Seek Professional Help

• If you cannot resolve the issue on your own, it is advisable to take your vehicle to a certified Toyota service center. Professional technicians can accurately diagnose and fix the problem.
