Cleaning the Mirror
When cleaning the mirror, use a paper towel or
similar material dampened with glass cleaner.
Do not spray glass cleaner directly on the mirror
as that may cause the liquid cleaner to enter
the mirror housing.

Automatic Dimming Mirror Operation
O
:Press this button to turn the automatic
dimming feature on or off. The indicator light to
the left of the button will turn on or off to indicate
when the feature is on. Once the mirror is
turned off, it will remain off until it is turned back
on, or until the vehicle is restarted.
Compass Operation
Press the compass/temperature button once
briey to turn the display on or off.
Compass Calibration
The compass may need calibration if one of the
following occurs:
If CAL is displayed while driving in the vehicle.
After approximately ve seconds, the display
does not show a compass heading, N for
North, for example, there may be a strong
magnetic eld interfering with the compass.
Such interference may be caused by a
magnetic antenna mount, magnetic note pad
holder, or a similar magnetic item.
The compass does not display the correct
heading and the compass zone variance
is set correctly.
In order to calibrate, CAL must be displayed in the
mirror compass windows. If CAL is not displayed,
push in the compass/temperature button for
approximately nine seconds or until CAL is
displayed.
The compass can be calibrated by driving the
vehicle in circles at 5 mph (8 km/h) or less until the
display reads a direction.
161

Compass Variance
The mirror is set in zone eight upon leaving the
factory. It will be necessary to adjust the compass
to compensate for compass variance if the
vehicle is outside zone eight. Under certain
circumstances, as during a long distance
cross-country trip, it will be necessary to adjust for
compass variance. Compass variance is the
difference between earth’s magnetic north and true
geographic north. If not adjusted to account for
compass variance, your compass could give false
readings.
To adjust for compass variance:
1. Find your current location and variance zone
number on the following zone map.
2. Press and hold the compass/temperature
button for six seconds until a zone number
appears in the display.
3. Press the compass/temperature button on the
bottom of the mirror until the new zone
number appears in the display. After you stop
pressing the button, the display will show a
compass direction within a few seconds.

the lamp and illuminate an indicator light near the
button. Pressing the button again will turn off
the roof mounted lamp.
If your vehicle has this button, your vehicle may
have the snow plow prep package. For further
information seeAdding a Snow Plow or Similar
Equipment on page 396.

203

The display is located
near the passenger side
rear window and can
be seen by looking over
your right shoulder.
The display has three color-coded lights.
The URPA lights are used to provide distance
and system information, along with beeps that will
be heard through the speakers.
URPA can be turned off
by pressing the rear
park aid disable button
located next to the
radio. The indicator will
illuminate to indicate
that URPA is off.The red light in the URPA display will also be lit if
the vehicle is in REVERSE (R). If the vehicle
has a DIC, PARKING ASSIST OFF will display.
URPA automatically turns back on each time
the vehicle is started.
How the System Works
When the shift lever is moved into REVERSE (R),
the rear display will briey come on to let you know
the display is operating correctly. URPA comes on
automatically when the shift lever is moved into
REVERSE (R). The system also does not work at a
reverse speed greater than 5 mph (8 km/h).
To remind you of this, the red light on the rear
display will ash.
The system can be disabled using the Driver
Information Center (DIC). SeeDIC Operation and
Displays (With DIC Buttons) on page 244or
DIC Operation and Displays (Without DIC Buttons)
on page 251.
206

How the System Works when Backing
If the shift lever is in REVERSE (R), URPA detects
objects close to the rear bumper. The rst time an
object is detected a single beep will sound. If an
object is detected at a REVERSE (R) speed
between 0 mph (0 km/h) and 5 mph (8 km/h), the
following describes what will occur based on your
distance to a detected object located behind the
vehicle:
At distances between 40 inches (1 m) and
8 ft (2.5 m), a single amber light will come on.
At distances between 23 inches (0.6 m) and
40 inches (1 m), both amber lights will be on.
At distances between 12 inches (0.3 m) and
23 inches (0.6 m), all three lights (amber/
amber/red) will be on.
At distances less than 12 inches (0.3 m), a
beeping sound will repeat for a short time and
all three lights (amber/amber/red) will be on and
ashing.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a
temporary condition, the message PARKING
ASSIST OFF will be displayed on the DIC and a
red light will be shown on the rear URPA display
when the shift lever is moved into REVERSE (R).
This occurs under the following conditions:
The driver disables the system. SeeDIC
Operation and Displays (With DIC Buttons)
on page 244orDIC Operation and Displays
(Without DIC Buttons) on page 251.
The parking brake pedal is depressed.
A trailer was attached to your vehicle, or a
bicycle or an object was hanging out of your
trunk during your last drive when you turned off
the vehicle. If the attached objects are removed
from your vehicle before the start of your next
drive, the system will return to normal operation
unless an object is detected when the vehicle is
shifted into REVERSE (R). If this occurs, URPA
assumes the object is still attached, so you will
have to wait until the vehicle is driven forward
above 15 mph (25 km/h) before URPA will
return to normal operation.
207

The ultrasonic sensors are not kept clean.
So, be sure to keep your vehicle’s rear bumper
free of mud, dirt, snow, ice, and slush. For
cleaning instructions, seeWashing Your
Vehicle on page 532. If the DIC still displays the
PARKING ASSIST OFF message after
cleaning the bumper and driving forward at a
speed of at least 15 mph (25 km/h), see your
dealer.
Other conditions that may affect system
performance include vibrations from a
jackhammer or the compression of air brakes
on a very large truck or other mechanical
devices that interfere with URPA performance.
When URPA is disabled without driver action
and the driver attempts to turn URPA back on
using the Driver Information Center (DIC), the
PARKING ASSIST ON option will not be
selectable if the necessary conditions stated
above for normal system operation are not met.
As always, drivers should use care when backing
up a vehicle. Always look behind you, being
sure to check for other vehicles, obstructions and
blind spots.For Driver Information Center messages related to
URPA, seeDIC Warnings and Messages on
page 254.
If the bumper is damaged, your URPA system
may not work properly. Take the vehicle to
your dealer to repair the system.
Accessory Power Outlet(s)
With accessory power outlets you can plug in
auxiliary electrical equipment, such as a cellular
telephone or CB radio.
Your vehicle will have two accessory power
outlets under the climate controls, one on the back
of the oor console and a additional accessory
power outlet in the rear cargo area on the
passenger side.
To use the power outlet, lift the spring cap and
insert electrical 12V device plug. To close
the power outlet, remove 12V electrical device
plug and the spring cap will close.
Certain power accessory plugs may not be
compatible to the accessory power outlet and
could result in blown adapter or vehicle fuses.
