Daytime Running

Lamps (DRL)

DRL can make it easier for others to
see the front of the vehicle during
the day. Fully functional daytime
running lamps are required on all
vehicles first sold in Canada.
The DRL system comes on in
daylight when the following
conditions are met:
The ignition is on.
The exterior lamp control is in
the AUTO position.
The shift lever is not in P (Park).
The light sensor determines it is
daytime.
When the DRL are on, the taillamps,
sidemarker, instrument panel lights,
and other lamps will not be on.
The automatic headlamp system
automatically switches from DRL to
the headlamps depending on the
darkness of the surroundings.
To turn off the DRL, turn the exterior
lamp control to
and then release
it. For vehicles first sold in Canada,
the transmission must be in the
P (Park) position, before the DRL
can be turned off.

Automatic Headlamp

System

When it is dark enough outside and
the headlamp switch is in AUTO,
the automatic headlamp system
turns on the headlamps, along with
the taillamps, sidemarker lamps,
parking lamps, and the instrument
panel lights. The radio lights will
also be dim.
To turn off the automatic headlamp
system, turn the exterior lamp
control to the off position and then
release. For vehicles first sold in
Canada, the transmission must be
in the P (Park) position, before the
automatic headlamp system can be
turned off.
Lighting
The vehicle has a light sensor
located on the top of the instrument
panel. Do not cover the sensor;
otherwise the system will come on
whenever the ignition is on.
The system may also turn on the
headlamps when driving through a
parking garage or tunnel.
There is a delay in the transition
between the daytime and nighttime
operation of the Daytime Running
Lamps (DRL) and the automatic
headlamp system so that driving
under bridges or bright overhead
street lights does not affect the
system. The DRL and automatic
headlamp system are only affected
