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
lights will come on when all of the
following conditions are met:
. The engine is running
. The exterior lamp band is
in AUTO
. The light sensor determines it is
daytime.
When the DRL are on, the
low-beam headlamps will be on.
The taillamps, sidemarker,
instrument panel lights and other
lamps will not be on.
The DRL turn off when the
headlamps are turned to
O
or the
ignition is off.
Automatic Headlamp
System
When the exterior lamp control is
set to AUTO and it is dark enough
outside, the headlamps come on
automatically.
There is a light sensor located on
top of the instrument panel. Do not
cover the sensor or the headlamps
will come on when they are not
needed.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
When it is bright enough outside the
headlamps will turn off or may
change to daytime running
lamps (DRL).
The automatic headlamp system
turns off when the exterior lamp
control is turned to

is off.
