Interior Lamps

Instrument Panel Intensity Control
The instrument panel intensity control is located to the
right of the headlamp switch.
Rotate the thumbwheel up to adjust the instrument panel
lights. To turn on the dome lamps (with the vehicle
doors closed) rotate the thumbwheel all the way up.

Exit Lighting

With exit lighting, the interior lamps will come on when
you remove the key from the ignition. The lights will
not come on If the DOME OVERRIDE button is
pressed in.

Illuminated Entry

Your vehicle is equipped with an illuminated
entry feature.
When the doors are opened, the dome lamps will come
on if the DOME OVERRIDE button is in the "out"
position. When all the doors are closed, or the front door
handles are pulled and released, the lamps will stay on
for a short period of time and will then go out. If the
DOME OVERRIDE button is pressed in, the lamps will
not come on.
