Daytime Running Lamps / Automatic
Headlamp Control
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 lights are required on all
vehicles first sold in Canada.
A light sensor on top of the instrument panel makes the
DRL work, so be sure it isn’t covered.
The DRL system will make your high
-
beam headlamps
come on at a reduced brightness when the following
conditions are met:
D The ignition is on,
D the headlamp switch is off and
D the parking brake is released.
When the DRL are on, only your reduced intensity
high
-
beam headlamps will be on. The taillamps,
sidemarker and other lamps won’t be on.
Your instrument panel won’t be lit up either.
When it’s dark enough outside, your DRL will turn
off and your low
-
beam headlamps will illuminate.
The other lamps that come on with your headlamps
will also come on.
When it’s bright enough outside, the low
-
beam
headlamps will go out, and DRL illuminates your
high
-
beam headlamps at reduced intensity.
To idle your vehicle with the DRL off, set the parking
brake while the ignition is in OFF or LOCK. Then start
your vehicle. The DRL will stay off until you release the
parking brake.
As with any vehicle, you should turn on the regular
headlamp system when you need it.

This thumbwheel is located next to the exterior lamps
control and is shown as (A) in the previous photo.
You can brighten or dim the instrument panel lights by
moving the thumbwheel up or down. If you turn the
thumbwheel all the way up, your courtesy or interior
lamps will come on.
