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.
The dedicated 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 vehicle is not parked.
The taillamps, instrument panel
lights, and other lamps will not
be on.
The DRL turn off when the
headlamps are turned to
ignition is off. For vehicles sold in
Canada, this control only works
when the vehicle is parked.
Automatic Headlamp

System

There is a light sensor 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.
Lighting
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 changes to the
Daytime Running Lamps (DRL).
During that delay, the instrument
cluster may not be as bright as

When it is bright enough outside,
the headlamps will turn off or may
change to DRL.
The automatic headlamp system
turns off when the exterior lamp
control is turned to or the ignition
is off.
