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 16L286 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 switch changes the mode between "AUTO" and "DAY". The indicator comes on when the "AUTO" 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 inside rear view mirror surface changes, the outside rear view mirror surfaces will also become darker. When the ignition switch is turned on, the inside rear view mirror always turns on in the "AUTO" mode. 231
