The exterior lamps control is located on the instrument panel to the left of the steering wheel.

It controls the following systems:

    • Headlamps
    • Taillamps
    • Parking Lamps
    • License Plate Lamps
    • Instrument Panel Lights

The exterior lamps control has three positions:

Off: Push the control all the way in to turn off the exterior lamps.

Parking Lamps: Pull the control out halfway to turn on the parking lamps together with the following:

    • Taillamps
    • License Plate Lamps
    • Instrument Panel Lights
Headlamps: Pull the control all the way out to turn on the headlamps together with the previously listed lamps and lights. See Interior Lamps for information on the instrument panel brightness control and on the dome lamps. A warning chime will sound if you open the driver's door when the ignition switch is off and the headlamps are on.

Daytime Running Lamps/Automatic Headlamp System

Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. DRL can be helpful in many different driving conditions, but they can be especially helpful in the short periods after dawn and before sunset. Fully functional daytime running lamps are required on all vehicles first sold in Canada.

A light sensor on top of the instrument panel makes the DRL work, so be sure it isn't covered.

The DRL system's automatic headlamp control will make your high-beam headlamps come on at a reduced brightness when the following conditions are met:

    • The ignition is on,
    • the exterior lamps control is off and
    • the gearshift is not in PARK (P).

When the DRL are on, only your high-beam headlamps, at a reduced level of brightness, will be on. The headlamps, taillamps, sidemarker and other lamps won't be on. Your instrument panel and cluster won't be lit up either.

When it's dark enough outside, your high-beam headlamps will turn off and the headlamps and parking lamps will turn on. The other lamps that come on with your headlamps will also come on.

When it's bright enough outside, your headlamps will go off and your DRL will come on.

As with any vehicle, you should turn on the regular headlamp system when you need it.

Delayed Headlamps

The delayed headlamps feature provides a period of exterior lighting as you leave the area around your vehicle. The feature is activated when the headlamps are on due to the automatic headlamps control feature described previously in this section, and when the ignition is turned off. Your headlamps will then remain on until the exterior lamps control is moved to the parking lamps position or until either a 30 second or 60 second lighting period has ended.

If you turn off the ignition with the headlamps switch in the parking lamps or headlamps position, the delayed headlamps cycle will not occur.

To disable the delayed headlamps feature or change the time of delay, see Vehicle Customization Settings .

Fog Lamps


Object Number: 805533  Size: A3

If your vehicle is equipped with fog lamps, the button is located on the instrument panel next to the exterior lamps control wheel to the left of the steering column.

Your ignition must be in ON for the fog lamps to illuminate.

To turn the fog lamps on, press the FOG button. A light will come on in the button to let you know that the fog lamps are on. Press the FOG button again to turn the fog lamps off.

The ignition must be ON and the parking lamps must be on for your fog lamps to work.

The fog lamps will go off while you change to high-beam headlamps.
