Press the knob located next to the exterior lamps knob to extend it.

Turn the knob to adjust the instrument panel lights. Turn the knob all the way up to turn on the interior lamps. Press the knob back into its stored position when you're not using it.

Dome Lamp Override


Object Number: 806779  Size: A2

The dome override button is located below the exterior lamps knob.

To turn the dome lamps off, press the button. The dome lamps will remain off when a door is open. This will override the illuminated entry feature unless you use your keyless entry transmitter to unlock the vehicle.

To return the lamps to automatic operation, press the button again. The dome lamps will come on when you open a door.

Entry Lighting

Your vehicle is equipped with entry lighting.

When a door is opened, the dome lamps will come on if the dome override button is in the "out" position. When all the doors are closed, the lamps will stay on for a short period of time and will then turn off automatically. If you use your keyless entry transmitter to unlock the vehicle, the interior lights will come on for a short time whether or not the dome override is on.

Exit Lighting

With exit lighting, the interior lamps will come on when you remove the key from the ignition to help you see while exiting the vehicle. With the dome override button in the "out" position, these lights will stay on for a short period of time and then will go out.

Reading Lamps


Object Number: 807767  Size: B1

Press the lens on the lamp located above the doors to turn the reading lamps on and off.

Dome Lamps

The dome lamps will come on when you open a door unless the dome lamp override is pressed in.

You can also turn the dome lamps on by turning the thumbwheel, located next to the exterior lamps knob, all the way up to the top detent position. In this position, the dome lamps will remain on until they are turned off.

Battery Run-Down Protection

This feature shuts off the dome, courtesy, vanity, and reading lamps if they are left on for more than 20 minutes when the ignition is off. This will keep your battery from running down.

If the battery run-down protection shuts off the interior lamps, it may be necessary to do one of the following to return to normal operation:

    • Shut off all lamps and close all doors, or
    • turn the ignition key to RUN.

This feature will also turn off the parking lamps and headlamps under most circumstances, if they are left on. If you would like to turn them back on, turn the exterior lamps knob.
