The exterior lamp band on the turn signal/multifunction lever controls the exterior lamps.

The exterior lamp band has three positions:

OFF: Turning the band to this position turns off all lamps, except the Daytime Running Lamps (DRL).

(Parking Lamps): Turning the band to this position turns on the parking lamps, together with the following:

    • Sidemarker Lamps
    • Taillamps
    • Instrument Panel Lights
(Headlamps): Turning the band to this position turns on the headlamps, together with the previously listed lamps and lights.

Lamps On Reminder

If you open the driver's door with the ignition off and the lamps on, you will hear a warning chime.

Daytime Running Lamps

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.

The DRL system will make your low-beam headlamps come on at a reduced brightness in daylight when the following conditions are met:

    • The ignition is on,
    • the exterior lamp band is in OFF or in the parking lamp position,
    • the parking brake is released, and
    • the transaxle is not in PARK (P) on models with an automatic transaxle only.

This indicator light on your instrument panel cluster will come on when the DRL are on.

A flashing DRL telltale indicates a possible burned out headlamp, or that the vehicle may need service to repair a stuck DRL relay.

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

When you turn the exterior lamp band to the headlamp position, your low-beam headlamps will come on. The other lamps that come on with your headlamps will also come on.

When you turn off the headlamps, the regular lamps will go off, and low-beam headlamps will come on to the reduced brightness.

To idle your vehicle with the DRL off, set the parking brake. The DRL will stay off until you release the parking brake.

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

Fog Lamps

If your vehicle has this feature, use your fog lamps for better visibility in foggy or misty conditions.

The button for your fog lamps is located next to the instrument panel brightness control.

Push the top of the button to turn the fog lamps on. Push the top of the button again to turn the fog lamps off.

When using fog lamps, the parking lamps or low-beam headlamps must be on.

A light on the button will come on when the fog lamps are actually on. Fog lamps will go off whenever the high-beam headlamps come on. When the high-beam headlamps go off, the fog lamps will come on again.

Continuous use of the fog lamps will shorten bulb life. Limit use as necessary.
