Lighting 5-3
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 will make either
the reduced intensity low-beam
headlamps or dedicated DRL's
come on when the following
conditions are met:
. It is still daylight and the ignition
is in ON/RUN or START.
. The exterior lamp control is in off
or AUTO and the headlamps
are off.
. The automatic transmission is
not in P (Park).
When DRL's are on, only the
reduced intensity low-beam
headlamps or dedicated DRL's will
be on. The other exterior lamps and
the instrument panel cluster will not
be on.
When the exterior lamp control is in
AUTO and it is dark enough outside,
the DRL turns off and the low-beam
headlamps will turn on. When it is
bright enough outside, the low-beam
headlamps will go off, and the DRL
will turn back on. If the vehicle is
started in a dark garage, the
automatic headlamp system comes
on immediately. Once the vehicle
leaves the garage, it takes about
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 lever is in the full bright
position. See
Instrument Panel
Illumination Control on page 5 ‑ 5 .
Turning the exterior lamp control to
off or to the low-beam headlamp
position will turn off the DRL. If the
parking lamps or the fog lamps were
turned on instead, the DRL will still
turn off.
This will work regardless of gear
position and whether or not the
parking brake is set.
