STEERING WHEEL AND MIRRORS INSIDE REAR VIEW MIRROR When the outside air temperature is low, it may take a little longer for the mirror to darken in response to the detection of headlights. CAUTION Do not adjust the mirror while the vehicle is moving. Doing so may cause the driver to mishandle the vehicle and an accident may occur resulting in death or serious injuries. Adjust the mirror so that you can just see the rear of your vehicle in the mirror. Pushing the "MIRROR" switch changes the mode between AUTO and DAY. The indicator comes on when the automatic function mode is selected. DAY mode: The mirror surface is normal. AUTO mode: If the mirror detects light from the headlights of the vehicle behind you, the mirror surface darkens slightly to reduce the reflected light. When the ignition key is inserted and turned on, the inside rear view mirror always turns on in the automatic function mode. To ensure correct functioning of anti−glare mirror sensors located on both sides of the mirror, do not touch or cover the sensors with your finger or a piece of cloth, etc. 206
