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 DRL are required on all vehicles first sold in Canada.

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

• The ignition is on.
• The exterior lamps knob is in automatic headlamp mode.
• The light sensor detects daytime light.
• The transmission is not in PARK (P).

When the DRL are on, only the headlamps will be on. The taillamps, sidemarker and other lamps will not be on. The instrument panel will not be lit up either.

When it begins to get dark, the headlamps automatically switch from DRL to the regular headlamps.
