Instrument Panel Brightness


Object Number: 880832  Size: A3

The instrument panel brightness control is located to the left of the steering wheel on the instrument panel.

The brightness of the instrument panel lights will decrease when the headlamps are on. It is recommended that the brightness level is kept at the maximum setting for all daytime driving to insure proper visibility.

The interior light has the following positions:

OFF:  This position turns the light off.

ON:  This position keeps the light on all the time.

(Door):  This position turns the light on when any of the side doors, the liftgate or the liftglass is opened. The light goes off when all the side doors, the liftgate and the liftglass are closed.

Entry Lighting

While the instrument panel brightness control is in the door position, the light will come on when any side door, the liftgate or the liftglass is opened. After all the side doors, liftgate and liftglass are closed, and the key is out of the ignition, in LOCK or ACC, the light will remain on for about 15 seconds and then go out except under the following conditions:

    • The ignition is turned to ACC or ON after all the side doors, the liftgate and the liftglass are closed.
    • All the side doors and liftgate are locked when the liftglass is closed and the light is still on.

When any side door is unlocked with the key or remote keyless entry system transmitter, the light comes on for 15 seconds, even if the door is not opened.

To prevent the battery from draining, the lamps will automatically turn off when the key is in the ACC or LOCK positions or if the key is removed for 20 minutes or more.
