Daytime Running Lamps (DRL)

DRL can make it easier for others to see the
front of your vehicle during the day. Fully
functional DRL are required on all vehicles
first sold in Canada.
If equipped, the DRL will come on when all
of the following conditions are met:
The ignition is on.
The exterior lamp control is in AUTO.
The light sensor determines it is daytime.
The DRL turn off when the headlamps are
turned to
or the ignition is off.
For vehicles first sold in Canada, the DRL can
only be turned off when the vehicle is
parked.

Automatic Headlamp System

When the exterior lamp control is set to
AUTO and it is dark enough outside, the
headlamps come on automatically.
The light sensor is on top of the instrument
panel or on the windshield near the
rearview mirror. 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.
If the vehicle is started in a dark garage, the
automatic headlamp system comes on
immediately. If it is light outside when the
vehicle leaves the garage, there is a slight
delay before the automatic headlamp
system turns off the headlamps. During that
delay, the instrument cluster may not be as
bright as usual. Make sure the instrument
panel brightness control is in the full bright
position. See Instrument Panel Illumination
Control 0 118.
When it is bright enough outside, the
headlamps will turn off.
The automatic headlamp system turns off
when the exterior lamp control is turned to
or the ignition is off. For vehicles sold in
Canada, this control only works when the
transmission is in P (Park).
Lights On with Wipers
If the windshield wipers are activated in
daylight with the engine on, and the
exterior lamp control is in AUTO, the
headlamps, parking lamps, and other
exterior lamps come on. The transition time
for the lamps coming on varies based on
wiper speed. When the wipers are not
operating, these lamps turn off. Move the
exterior lamp control to
or
this feature.
