off. Have your headlamp wiring checked right away if
this ever happens.

Headlamps On Reminder

If you have this system, a tone will sound when your
headlamps and/or parking lamps are turned on and your
ignition is in LOCK or ACCESSORY.

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 headlamps come on
at reduced brightness when the following conditions
are met:
•
The ignition is on,
•
the exterior lamp control is off, and
•
the parking brake is released.
