The exterior lamp control is located on the lower left side of the instrument panel, to the left of the steering wheel.

The exterior lamp has three positions.

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

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

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

A warning chime will sound if you open the driver's door when you turn the ignition switch to LOCK or ACCESSORY with the lamps on.

Daytime Running Lamps (DRL) / 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 will make your low-beam headlamps come on at a reduced brightness when the following conditions are met:

    • The ignition is on,
    • the exterior lamps control is off,
    • the transaxle is not in PARK (P) and
    • the parking brake is released.

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

When it's dark enough outside, your headlamps will change to full brightness. The other lamps that come on with your headlamps will also come on.

When it's bright enough outside, the headlamps will go out, and your low-beam headlamps will change to the reduced brightness of DRL.

To idle your vehicle with the DRL off, set the parking brake while the ignition is in OFF or LOCK. Then start your vehicle. The DRL will stay off until you shift out of PARK (P) and release the parking brake.

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