Lighting 6-3
Daytime Running Lamps
(DRL)/Automatic
Headlamp System
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
low-beam headlamps come on
at a reduced brightness when
the following conditions are met:
.The ignition is in the ON/RUN
position.
.The exterior lamps control is
in AUTO.
.The engine is running.When the DRL are on, the regular
headlamps, taillamps, sidemarker,
and other lamps will not be on. The
instrument panel and cluster will
also not be lit.
The headlamps automatically
change from DRL to the regular
headlamps depending on the
darkness of the surroundings. The
other lamps that come on with the
headlamps will also come on.
When it is bright enough outside,
the headlamps will go off and the
DRL will come on.
The regular headlamp system
should be turned on when needed.
Do not cover the light sensor on top
of the instrument panel because it
works with the DRL.
Delayed Headlamps
Delayed headlamps provide a
period of exterior lighting as you
leave the area around the vehicle.
This feature is activated when the
headlamps are on due to the
automatic headlamps control
feature, and when the ignition is
turned off. The headlamps remain
on until the exterior lamps control is
moved to the parking lamps position
or until the pre-selected delayed
headlamp lighting period has ended.
If the ignition is turned off with the
exterior lamp control in the parking
lamps or headlamps position, the
delayed headlamps cycle will not
occur.
To disable the delayed headlamps
feature or change the time of delay,
see
Vehicle Personalization (With
DIC Buttons) on page 5‑40.

8-8 Climate Controls
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
1(Rear Window Defogger):
Press to turn the rear window
defogger on or off. The rear window
defogger stays on for about
10 minutes, before turning off. The
defogger also turns off when the
engine is turned off. Do not drive the
vehicle until all the windows are
clear.
For vehicles with heated outside
rearview mirrors, fog or frost is
cleared from the surface of the
mirror when the rear window defog
button is pressed.
Notice: Do not use a razor blade
or sharp object to clear the inside
rear window. Do not adhere
anything to the defogger grid
lines in the rear glass. These
actions may damage the rear
defogger. Repairs would not be
covered by your warranty.
Sensors
The solar sensor, located in the
defrost grille in the middle of the
instrument panel, monitors the solar
heat. Do not cover the solar sensor
or the system will not work properly.
The interior temperature sensor
located on the instrument panel to
the right of the steering column,
measures the temperature of the air
inside the vehicle.
There is also an exterior
temperature sensor located behind
the front grille. This sensor reads
the outside air temperature and
helps maintain the temperature
inside the vehicle. Any cover on the
front of the vehicle could cause a
false reading in the displayed
temperature.

Climate Controls 8-9
The climate control system uses the
information from these sensors to
maintain comfort settings by
adjusting the temperature, fan
speed, and air delivery mode. The
system may also supply cooler air to
the side of the vehicle facing the
sun. The recirculation mode will also
be used as needed to maintain cool
outlet temperatures.Rear Climate Control System (Rear Climate
Control Only)
A. Fan Control
B. Temperature Control
C. Air Delivery Mode Control
For vehicles with the rear climate
control system, the controls are
located on the rear of the center
console. The system can also be
controlled with the front controls.Press the REAR button on the front
climate control system to turn the
rear climate control system on or
off. An indicator comes on when the
rear system is on. The system also
turns on if any of the rear controls
are adjusted.

This mode matches
the rear climate control to the front
climate control settings. It comes on
when REAR is pressed.

Object Detection
Systems
Ultrasonic Parking Assist
If available, the Ultrasonic Rear
Parking Assist (URPA) system
assists the driver with parking
and avoiding objects while in
R (Reverse). URPA operates at
speeds less than 8 km/h (5 mph).
The sensors on the rear bumper
are used to detect objects up to
2.5 m (8 ft) behind the vehicle, and
at least 25 cm (10 in) off the ground.
{WARNING
The URPA system does not
detect pedestrians, bicyclists,
animals, or any other objects
located below the bumper or that
are too close or too far from the
vehicle. To prevent injury, death,(Continued)
WARNING (Continued)
or vehicle damage, even with
URPA, always check behind the
vehicle and check all mirrors
before backing.
How the System Works
URPA comes on automatically
when the shift lever is moved into
R (Reverse). A single tone sounds
to indicate the system is working.
URPA operates only at speeds less
than 8 km/h (5 mph).
An obstacle is indicated by audible
beeps. The interval between the
beeps becomes shorter as the
vehicle gets closer to the obstacle.
When the distance is less than
30 cm (12 in) the beeping is a
continuous tone for five seconds. To be detected, objects must be at
least 25 cm (10 in) off the ground
and below liftgate level. Objects
must also be within 2.5 m (8 ft) from
the rear bumper. This distance may
be less during warmer or humid
weather.
Turning the System On and Off
The system can be disabled through
the Driver Information Center (DIC).
See
“Park Assist” underVehicle
Personalization (With DIC Buttons)
on page 5‑40 for more information.
URPA defaults to the on setting
each time the vehicle is started.
When the System Does Not
Seem to Work Properly
The following messages may be
displayed on the DIC:
SERVICE PARK ASSIST: If this
message occurs, take the vehicle to
your dealer to repair the system.

PARK ASST BLOCKED SEE
OWNERS MANUAL:This
message can occur under the
following conditions:
.The ultrasonic sensors are not
clean. Keep the vehicle's rear
bumper free of mud, dirt, snow,
ice, and slush. For cleaning
instructions, see Exterior Care
on page 10‑83.
.The park assist sensors are
covered by frost or ice. Frost or
ice can form around and behind
the sensors and may not always
be seen; this can occur after
washing the vehicle in cold
weather. The message may not
clear until the frost or ice has
melted.
.A trailer was attached to the
vehicle, or an object was
hanging out of the liftgate during
the last drive cycle. Once the
object is removed, URPA will
return to normal operation.
.A tow bar is attached to the
vehicle.
.The bumper is damaged. Take
the vehicle to your dealer to
repair the system.
.Other conditions, such as
vibrations from a jackhammer or
the compression of air brakes on
a very large truck, are affecting
system performance.
Rear Vision
Camera (RVC)
The vehicle may have a rear vision
camera system. Read this entire
section before using it.
{WARNING
The RVC system does not display
pedestrians, bicyclists, animals,
or any other object located
outside the cameras field of view,
below the bumper, or under the
vehicle.
(Continued)
WARNING (Continued)
Do not back the vehicle using
only the RVC screen or by using
the screen during longer, higher
speed backing maneuvers,
or where there could be
cross-traffic. Perceived distances
may be different from actual
distances.
Failure to use proper care before
backing may result in injury,
death, or vehicle damage. Always
check before backing by checking
behind and around the vehicle.
Vehicles without Navigation
System
The rear vision camera system is
designed to help the driver when
backing up by displaying a view of
the area behind the vehicle. When
the key is in the ON/RUN position
and the driver shifts the vehicle into
