Interior Lamps

Instrument Panel Intensity Control

The instrument panel intensity control is located next to the parking/headlamp switch. Turn the thumbwheel up to adjust the instrument panel lights. Turn the thumbwheel up to the first notch to return the radio display and gear shift indicator LED display to full intensity when the headlamps or parking lamps are on. To turn on the dome lamps (with the vehicle doors closed) turn the thumbwheel up to the second notch position.

Exit Lighting and Delayed Illumination

With this feature, your interior lamps will come on and stay on for up to 25 seconds when entering the vehicle and up to 5 seconds when leaving your vehicle.

When the doors are opened, the dome lamps will only come on if the dome lamp button is in the out position. When all doors are closed or the dome lamp button is pressed in, the lamps will stay on for a short period of time and will then fade out.

Dome Lamps

The dome lamps will come on when you open the doors.

You can also turn the dome lamps on by turning the thumbwheel, located next to the parking/headlamps switch knob, all the way up to the second notch. In this position, the dome lamps will remain on whether the doors are opened or closed.

You can use the DOME OVERRIDE button, located below the parking/headlamp knob, to set the dome lamps to come on automatically when the doors are opened, or remain off. To turn the lamps off, press the button once. With the button in this position, the dome lamps will remain off when the doors are open. To return the lamps to automatic operation, press the button again and return it to the “out” position. With the button in this position, the dome lamps will come on when you open the door.

Reading Lamps

Your vehicle has reading lamps. Press the button next to the lamp to turn the lamp on.

The lamps can be adjusted to point in the direction you want.

Press the button again to turn the lamp off.

Battery Rundown Protection

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