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 DRL system will make your low-beam headlamps
come on at a reduced brightness when the following
conditions are met:
• The ignition is on,
• the exterior lamps control is in AUTO or the parking
lamps only position,
• the light sensor detects daytime light,
• the parking brake is released, and
• the shift lever is not in PARK (P) on vehicles with
an automatic transaxle only.
When the DRL system is on, the taillamps, sidemarker
lamps, parking lamps and instrument panel lights
will not be illuminated unless you have turned the
exterior lamps control to the parking lamp position.
As with any vehicle, you should turn on the regular
headlamp system when you need it.
