Instrument Panel Brightness Control

This feature controls the brightness of the instrument panel lights.

The thumbwheel for this feature is located to the right of the exterior lamp control.

Turn the thumbwheel up to brighten the lights. When the thumbwheel is moved to the first position, the radio display and transmission selection display will go to full intensity. The instrument panel cluster will also be dimly lit. Moving the thumbwheel up to the next position will activate the interior dome lamps.

Dome Lamps

The dome lamps will come on when you open a door.

You can also turn the dome lamps on by moving the thumbwheel, located to the right of the exterior lamp control, all the way up to the second position. In this position, the dome lamps will remain on whether a door is open or closed.

You can use the dome override button to set the dome lamps to automatically come on when a door is open, or to remain off.
