2019 Acura ILX Owners Manual - Auto High Beam

The front sensor camera detects the light sources ahead of the vehicle such as the lights of a preceding or oncoming vehicle, or street lights. When you are driving at night, the system automatically switches the headlights between low beam and high beam depending on the situation.

If the camera receives a strong impact or requires repair, consult a dealer.

If you see the message “Some Driver Assist Systems Cannot Operate: Clean Front Windshield", park your vehicle in a safe place. Wipe away debris blocking the windshield, then start driving again. If the message remains even after driving for a while with the clean windshield, have your vehicle checked by a dealer.

If you see a message that the camera is too hot, use the climate control system to cool the interior. Defroster mode will direct airflow toward the camera.
