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 makes the front turn signal lamps
come on when the following conditions are met:
It is still daylight and the ignition is on.
The exterior lamp control is in the AUTO position.
The transmission is not in P (Park) or the parking
brake is off.
The parking brake is off or the vehicle speed is
greater than 8 mph (13 km/h).
When DRL are on, only the front turn signal lamps will
be on. The parking lamps, taillamps, instrument panel
lights, or other exterior lamps will not be on when the
DRL are being used.
When it is dark enough outside, the front turn signal
lamps turn off and the normal low-beam headlamps
turn on.
When it is bright enough outside, the regular lamps
go off, and the front turn signal lamps will take over.
If the vehicle is started in a dark garage, the automatic
headlamp system comes on immediately. Once the
vehicle leaves the garage, it takes approximately
one minute for the automatic headlamp system to
change to DRL if it is light outside. During that delay, the
instrument panel cluster may not be as bright as usual.
Make sure the instrument panel brightness knob is in the
full bright position. See Instrument Panel Brightness on
page 3-19 for more information.
If it is dark enough outside and the exterior lamp control
is off, a HEADLAMPS SUGGESTED message will
display on the Driver’s Information Center (DIC).
See DIC Warnings and Messages on page 3-56.
Turning the exterior lamp control to off a second
time, or turning on the headlamps will remove the
HEADLAMPS SUGGESTED message in the DIC.
If the parking lamps or the fog lamps were turned on
instead, the HEADLAMPS SUGGESTED message
will continue to be displayed.
The regular headlamp system should be turned on
when needed.
To turn off the DRL, turn the exterior lamp control to
the off position or shift into P (Park). The DRL will stay off
until the control is toggled again or the vehicle is shifted
out of P (Park).
This procedure applies only to vehicles first sold in the
United States.
