Outside Temperature
Outside temperature is shown in the mirror display.
Temperature will be displayed in Fahrenheit or
Celsius based on the choice of English or metric
in the vehicle’s con guration menu.
If an abnormal temperature reading is displayed for
an extended period of time, please consult your
dealer/retailer. Under certain circumstances, a delay
in updating the temperature is normal.
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 Rearview
Mirror with OnStar
®, Compass and
Temperature Display
Your vehicle may have this feature. When on, the
automatic dimming mirror dims to the proper level to
minimize glare from lights behind you after dark.
The mirror has a dual display in the upper right corner
of the mirror face that shows the compass reading
and the outside temperature.
Control buttons for the OnStar
®system, if equipped,
are at the bottom of the mirror. SeeOnStar®System
on page 2-56for more information about the services
OnStar
®provides.

Temperature and Compass Display
Press the on/off button, located on the far left
of the mirror face, to turn the compass/temperature
display on or off.
If the display reads CAL, the compass needs
to be calibrated. For more information, see
“Compass Calibration” following.
To adjust between Fahrenheit and Celsius,
do the following:
1. Press and hold the on/off button until either
a ashing F or C appears.
2. Press the button again to change the display
to the desired unit of measurement. After
approximately four seconds of inactivity,
the new unit will be locked in and the
compass/temperature display will return.
If an abnormal temperature reading is displayed
for an extended period of time, please see your
GM dealer. Under certain circumstances, a delay
in updating the temperature is normal.
Automatic Dimming Mirror Operation
The automatic dimming mirror function is turned
on automatically each time the ignition is started.
To operate the automatic dimming mirror,
do the following:
1. Make sure the green indicator light, located
to the left of the on/off button, is lit. If it is not,
press and hold the on/off button until the
green light comes on, indicating that the mirror
is in automatic dimming mode.
2. Turn off the automatic dimming mirror function
by pressing and holding the on/off button until
the green indicator light turns off.

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 of 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, the compass could give false readings.To adjust for compass variance, do the following:
1. Find your current location and variance
zone number on the following zone map.
2. Press and hold the on/off button until a Z and a
zone number appears in the display. The compass
is now in zone mode.
2-50

3. Keep pressing the on/off button until the desired
zone number appears in the display. Release
the button. After approximately four seconds of
inactivity, the new zone number will be locked
in and the compass/temperature display will return.
4. Calibrate the compass as described next.
Compass Calibration
The compass may need calibration if one of the
following occurs:
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 the on/off button for approximately 12 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.
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.

Object Detection Systems
Ultrasonic Rear Parking
Assist (URPA)
If your vehicle has the Ultrasonic Rear Parking Assist
(URPA) system, it helps you park easier and avoid
other vehicles while in REVERSE (R). It operates
at speeds less than 5 mph (8 km/h). It can determine
how close objects are to the rear bumper, up to
8 feet (2.5 m) behind your vehicle. The distance
sensors are located on the rear bumper.
{CAUTION:
The Ultrasonic Rear Parking Assist (URPA)
system does not replace driver vision.
It cannot detect:
objects that are below the bumper,
underneath the vehicle, or if they are
too close or far from the vehicle
children, pedestrians, bicyclists, or pets.
CAUTION: (Continued)
CAUTION: (Continued)
If you do not use proper care before and
while backing; vehicle damage, injury, or
death could occur. Even with URPA, always
check behind your vehicle before backing up.
While backing, be sure to look for objects
and check your vehicle’s mirrors.
On some vehicles
this display is located
above the rear window
towards the center of
the vehicle and can be
seen by looking over
your right shoulder.
If your vehicle has the display, there are three
color-coded lights to provide distance and system
information.
If your vehicle does not have the display and it has
URPA, you will hear the beeps as described in the
following information.
2-54
Page 133 of 496
How the System Works
URPA comes on automatically when the shift lever is
moved into REVERSE (R). The rear display will then
brie y illuminate to let you know the system is working.
URPA operates only at speeds less than 5 mph (8 km/h).
If you are above this speed, the red light on the rear
display will ash.
To be detected, objects must be at least 10 inches
(25.4 cm) off the ground and below Midgate
®/tailgate
level. Objects must also be within 8 feet (2.5 m) from
your rear bumper. This distance may be less during
warmer or humid weather.
A single beep will sound the rst time an object is
detected between 20 inches (0.5 m) and 8 feet (2.5 m)
away. Beeping will occur for three seconds when
you are closer than 1 foot (0.3 m) from the object.The following describes what will occur with the
URPA display as you get closer to a detected object:
Description English Metric
amber light 8 ft 2.5 m
amber/amber lights 40 in 1.0 m
amber/amber/red lights 23 in 0.6 m
amber/amber/red lights
ashing and beep
for three seconds1 ft 0.3 m
The system can be
disabled by pressing the
rear park aid disable button
located next to the radio.
The indicator light will
come on to indicate that
URPA is off.
Notice:If you use URPA while the tailgate is
lowered, it may not detect an object behind your
vehicle, and you might back into the object and
damage your vehicle. Always verify the tailgate is
closed when using URPA or turn off URPA when
driving with the tailgate lowered.

When the System Does Not Seem
to Work Properly
The driver disables the system.
The parking brake pedal is depressed.
The ultrasonic sensors are not clean. Keep your
vehicle’s rear bumper free of mud, dirt, snow,
ice and slush. For cleaning instructions, see
Washing Your Vehicle on page 5-101.
A trailer was attached to your vehicle, or a
bicycle or an object was hanging out of your
Midgate
®/tailgate during your last drive cycle,
the red light may illuminate in the rear display.
Once the attached object is removed, URPA
will return to normal operation.
A tow bar is attached to your vehicle.
The vehicle’s bumper is damaged. Take the
vehicle to your dealer/retailer to repair the system.
Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled, after driving forward
at least 15 mph (25 km/h), take your vehicle to your
dealer/retailer.
