Compass Calibration
See “Compass Calibration” underAutomatic
Dimming Rearview Mirror with OnStar®, Compass and
Temperature Display on page 2-56for more information.
Compass Variance
See “Compass Variance” underAutomatic
Dimming Rearview Mirror with OnStar®, Compass and
Temperature Display on page 2-56for more information.
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.
Outside Manual Mirrors
Adjust the outside mirrors to see the side of the vehicle
and have a clear view of objects behind you.
Manually fold the mirrors inward to prevent damage
when going through an automatic car wash. To fold, push
the mirror toward the vehicle. Push the mirror outward, to
return to its original position.
Using hood-mounted air deectors and add-on convex
mirror attachments could decrease mirror performance.

{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.
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.The display is located near
the passenger side rear
window and can be seen
by looking over your right
shoulder.
URPA uses three color-coded lights to provide distance
and system information.
How the System Works
URPA comes on automatically when the shift lever
is moved into R (Reverse). The rear display briey
illuminates to indicate the system is working.
URPA operates only at speeds less than 5 mph
(8 km/h). If the vehicle is above this speed,
the red light on the rear display will ash.
2-65

To be detected, objects must be at least 10 inches
(25.4 cm) off the ground and below tailgate level.
Objects must also be within 8 feet (2.5 m) from the
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 a short time when the
vehicle is closer than 1 foot (0.3 m) from the object.
The following describes what will occur with the URPA
display as the vehicle gets 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 mThe system can be
disabled by pressing the
rear park aid disable button
located next to the radio.
The indicator light will come on and PARKING ASSIST
OFF displays on the Driver Information Center (DIC)
to indicate that URPA is off, seeDIC Warnings
and Messages on page 3-66for information about
clearing the message.
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.
2-66

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
R (Reverse). This occurs under the following conditions:
The driver disables the system.
The parking brake pedal is depressed.
The ultrasonic sensors are not clean. Keep the
vehicle’s rear bumper free of mud, dirt, snow, ice and
slush. For cleaning instructions, seeWashing Your
Vehicle on page 5-118.
A trailer was attached to the vehicle, or a bicycle or
an object was hanging out of the tailgate during the
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 the 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 the vehicle to your
dealer/retailer.
OnStar®System
OnStar uses several innovative technologies and live
advisors to provide you with a wide range of safety,
security, information, and convenience services. If your
airbags deploy, the system is designed to make an
automatic call to OnStar Emergency advisors who can
request emergency services be sent to your location.
If you lock your keys in the vehicle, call OnStar at
1-888-4-ONSTAR and they can send a signal to unlock
your doors. If you need roadside assistance, press
the OnStar button and they can contact Roadside
Service for you.
OnStar service is provided to you subject to the
OnStar Terms and Conditions. You may cancel your
OnStar service at any time by contacting OnStar.
2-67

How OnStar Service Works
Your vehicle’s OnStar system has the capability
of recording and transmitting vehicle information.
This information is automatically sent to an OnStar
Call Center at the time of an OnStar button press,
Emergency button press or if your airbags or AACN
system deploys. The vehicle information usually includes
your GPS location and, in the event of a crash, additional
information regarding the accident that your vehicle has
been involved in (e.g. the direction from which your
vehicle was hit). When you use the Virtual Advisor feature
of OnStar Hands-Free Calling, your vehicle also sends
OnStar your GPS location so that we can provide you
with location-based services.
OnStar service cannot work unless your vehicle is in a
place where OnStar has an agreement with a wireless
service provider for service in that area. OnStar service
also cannot work unless you are in a place where the
wireless service provider OnStar has hired for that area
has coverage, network capacity and reception when the
service is needed, and technology that is compatible
with the OnStar service. Not all services are available
everywhere, particularly in remote or enclosed areas,
or at all times.Location information about your vehicle is only available
if the GPS satellite signals are unobstructed and
available.
Your vehicle must have a working electrical system
(including adequate battery power) for the OnStar
equipment to operate. There are other problems OnStar
cannot control that may prevent OnStar from providing
OnStar service to you at any particular time or place.
Some examples are damage to important parts of your
vehicle in an accident, hills, tall buildings, tunnels,
weather or wireless phone network congestion.
Your Responsibility
Increase the radio volume if you cannot hear the OnStar
advisor. If the light next to the OnStar buttons is red,
this means that your system is not functioning properly
and should be checked by your dealer/retailer. If the
light appears clear (no light is appearing), your OnStar
subscription has expired. You can always press the
OnStar button to conrm that your OnStar equipment
is active.

Be sure the cargo is properly loaded.
If small heavy objects are placed on the roof, cut a
piece of 3/8 inch plywood to t inside the crossrails
and siderails to spread the load. Tie the plywood
to the siderail supports.
Tie the load to the crossrails or the siderail
supports. Use the crossrails only to keep the load
from sliding. To move a crossrail, lift the release
lever, on both sides of the rail, up to loosen it. Slide
the crossrail to the desired position balancing the
force side to side. Press the release lever on both
sides of the rail, down to tighten it. Try to slide the
crossrail back and forth slightly to be sure it is tight.
If you need to carry long items, move the crossrails
as far apart as they will go. Tie the load to the
crossrails and the siderails or siderail supports. Also
tie the load to the bumpers. Do not tie the load so
tightly that the crossrails or siderails are damaged.
After moving a crossrail, be sure it is securely locked
into the siderail.Your vehicle has a Center High-Mounted
Stoplamp (CHMSL) located above the rear glass.
If items are loaded on the roof of the vehicle, care
should be taken not to block or damage the CHMSL unit.
Rear Seat Armrest
Your vehicle may have a rear seat armrest that contains
two cupholders. To access the cupholders, pull the
armrest down from the rear seatback.
Cargo Management System
Your vehicle may have a cargo management system.
It is located in the bed of the truck. The system contains
three rails located on the front and sides of the bed.
