Daytime Running Lamps (DRL)

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 ignition is on.
    • The exterior lamp band is in OFF or in the parking lamp position.
    • The parking brake is released.

When the DRL system is on, the taillamps, parking lamps and instrument panel lights will not be illuminated unless you have turned the exterior lamps control to the parking lamp or headlamp position.

An indicator light on the instrument panel cluster will come on when the DRL are on. See Daytime Running Lamps (DRL) Indicator Light .

    • The ignition is off.
    • The parking brakes are on.
    • The high-beam headlamps are on.
    • The low-beam headlamps are on.

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