Daytime Running Lamps (DRL) can make it easier for others to see the front of your vehicle during the day. Fully functional daytime running lamps are required on all vehicles first sold in Canada.

The DRL system will make the headlamps come on at reduced brightness when the following conditions are met:

    • The ignition is on.
    • The headlamp band is in the OFF position.
    • The parking brake is released.

When the DRL are on, only the low-beam headlamps will be on. The exterior lamps and instrument panel will not be lit.

When it begins to get dark, the DRL indicator light is a reminder to turn the headlamp switch on.

The other lamps that come on with the headlamps, will also come on.

When the headlamp band is turned to OFF, the regular lamps will go off, and the low-beam headlamps will change to the reduced brightness of DRL.

To idle the vehicle with the DRL off, set the parking brake. The DRL stays off until the parking brake is released.

Turn the regular headlamp system on when needed.
