Daytime Running Lamps (DRL)
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 turns on the low-beam headlamps at a reduced brightness. For vehicles with High Intensity Discharge (HID) headlamps, the dedicated DRL will come on when all of the following conditions are met:
• The ignition is on.
• The exterior lamps control is in AUTO.
• The light sensor determines it is daytime.
• The parking brake is released or the vehicle is not in P (Park).
When the DRL are on, the low-beam headlamps will be on.
The taillamps, sidemarker lamps, instrument panel lights, and other lamps will not be on.
The DRL turn off when the
headlamps are turned to 
or the
ignition is off.
This vehicle may have a DRL disabling function. When the DRL are on and a turn signal is activated, the DRL on that side will be off until the turn signal goes off.
