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 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 lamps,
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; otherwise 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.
