Instrument Panel Brightness

This feature controls the brightness of the instrument panel lights.

It is located on the driver's side of your instrument panel next to the exterior lamps control.

Turn the thumbwheel up to make your instrument panel lights brighter or down to dim them. Turn the thumbwheel all the way up to turn on the interior lamps.

Entry Lighting

Your vehicle is equipped with an entry lighting feature.

When any door is opened, the dome lamps will come on if the DOME OVERRIDE button is in the out position. If your vehicle is equipped with remote keyless entry and all the doors are closed, or the front door handles are lifted and released, the lamps will stay on for a short period of time and will turn off automatically. If you use your remote keyless entry transmitter to unlock the vehicle, the interior lights will come on for a short time whether or not the DOME OVERRIDE button is in the out position.

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. These lights will stay on for a short period of time and then will go out, if the DOME OVERRIDE button is in the out position.

Front Map Lamps

The front map lamps are located in the overhead console. The lamps will stay on for approximately 40 seconds after you exit the vehicle, unless you lock the doors with the remote keyless entry transmitter.

You can turn the lamps on and off by pressing the switch near each lamp.

Dome Lamp

The dome lamp will come on when you open any door.

You can also turn the dome lamps on by turning the instrument panel brightness thumbwheel, located next to the exterior lamps control, all the way up to the second notch. In this position, the dome lamps will remain on whether a door is opened or closed.

You can use the DOME OVERRIDE button, located below the exterior lamps control, to set the dome lamps to come on automatically when any door is opened, or to remain off. To turn the lamps off, press the button in. With the button in, the dome lamps will remain off when any door is opened. 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 any door. This will override the illuminated entry feature, unless you use your remote keyless entry transmitter (if equipped) to unlock the vehicle.

Battery Rundown Protection

This feature shuts off the dome, courtesy, vanity, reading, glove box, cargo 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.

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

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