Ultrasonic Rear Parking
Assist (URPA)
If your vehicle has the Ultrasonic Rear Parking
Assist (URPA) system it is designed to help
you park while in REVERSE (R). It operates only
at speeds less than 5 mph (8 km/h). URPA
helps make parking easier and helps you avoid
colliding with objects such as parked vehicles. The
URPA system detects objects that are close to
the rear of the vehicle which are at least 10 inches
(25.4 cm) off the ground and below hood or
tailgate level. The system detects objects up to
8 feet (2.5 m) behind your vehicle. The URPA
sensors determine how close these objects are
from your bumper within this area.
{CAUTION:
Even with the Ultrasonic Rear Park Assist
system, the driver must check carefully
before backing up. The system does not
CAUTION: (Continued)
CAUTION: (Continued)
operate above speeds of 5 mph
(8 km/h). The system does not detect
objects more than 8 feet (2.5 meters)
behind the vehicle. This detection
distance limit may be reduced during
warm weather or high humidity. Also, the
system does not detect objects that are
below your bumper, underneath your
vehicle, or some objects very close to the
vehicle. The system is not designed to
detect children, pedestrians, bicyclists,
or pets.
So, unless you check carefully behind
your vehicle while you are backing up,
they could be injured or killed.
Whether or not you are using rear park
assist, always check carefully behind your
vehicle before backing up and then watch
closely as you do.

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 501. 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 by pressing the rear park aid button, the
indicator light will ash for 3 seconds and then
stay lit to indicate that URPA is off.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 248.
If the vehicle bumper is damaged, the URPA
system may not work properly. Take the vehicle to
your dealer to repair the system.

instrument panel, which shows the airbag symbol.
The system checks the airbag’s electrical system
for malfunctions. The light tells you if there is an
electrical problem. The system check includes the
airbag sensors, the airbag modules, the wiring and
the crash sensing and diagnostic module. For more
information on the airbag system, seeAirbag
System on page 67.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds. Then
the light should go out.
This means the system
is ready.{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are
driving, your airbag system may not work
properly. Have your vehicle serviced right away.
The airbag readiness light should ash for a
few seconds when you turn the ignition key to
RUN. If the light does not come on then, have

SERVICE TIRE MONITOR SYSTEM
If your vehicle has the Tire Pressure Monitor
(TPM) system, this message will display if a part
on the system is not working properly. If you
drive your vehicle while any of the four sensors
are missing or inoperable, the warning will
come on in about 20 minutes. A sensor would
be missing, for example, if you put different wheels
on your vehicle without transferring the sensors.
If the warning comes on and stays on, there
may be a problem with the TPM. See your dealer.
SERVICE TRACTION CONTROL
If your vehicle has StabiliTrak®, this message will
display when there is a problem with the traction
control system. When this message is displayed,
the system will not limit wheel spin. Adjust
your driving accordingly. See your dealer for
service. SeeStabiliTrak
®System on page 330for
more information.
STABILITRAK OFF
If your vehicle has StabiliTrak®, this message will
display when you turn off StabiliTrak®, or when
the stability control has been automatically
disabled. To limit wheel spin and realize the full
benets of the stability enhancement system, you
should normally leave StabiliTrak
®on. However,
you should turn StabiliTrak®off if your vehicle gets
stuck in sand, mud, ice, or snow and you want
to rock your vehicle to attempt to free it, or if you
are driving in extreme off-road conditions and
require more wheel spin. SeeIf Your Vehicle is
Stuck in Sand, Mud, Ice, or Snow on page 370.
To turn the StabiliTrak
®system on or off, see
StabiliTrak®System on page 330.
There are several conditions that can cause this
message to appear.
One condition is overheating, which could
occur if StabiliTrak®activates continuously

High-Speed Operation
{CAUTION:
Driving at high speeds, 100 mph (160
km/h) or higher, puts an additional strain
on tires. Sustained high-speed driving
causes excessive heat build up and can
cause sudden tire failure. You could have
a crash and you or others could be killed.
Some high-speed rated tires require
ination pressure adjustment for high
speed operation. When speed limits and
road conditions are such that a vehicle
can be driven at high speeds, make sure
the tires are rated for high speed
operation, in excellent condition, and set
to the correct cold tire ination pressure
for the vehicle load.If your vehicle has P265/65R18 or P285/45R22
size tires and you will be driving at high speeds,
speeds of 100 mph (160 km/h) or higher, set
the cold ination pressure to 3 psi (20 kPa) above
the recommended tire pressure shown on the
Tire and Loading Information Label. When you end
this high-speed driving, return the tires to the
cold ination pressure shown on the Tire
and Loading Information label. SeeLoading Your
Vehicle on page 372andInation - Tire Pressure
on page 460.
Tire Pressure Monitor System
The Tire Pressure Monitor System (TPMS) uses
radio and sensor technology to check tire pressure
levels. If your vehicle has this feature, sensors
are mounted on each tire and wheel assembly,
except the spare tire. The TPMS sensors monitor
the air pressure in your vehicle’s tires and
transmit tire pressure readings to a receiver
located in the vehicle.
The TPMS is designed to alert the driver, if a low
tire pressure condition exists. If your vehicle has the
Driver Information Center (DIC), the driver may also
check tire pressure levels using the DIC.
462

Your vehicle’s TPMS can alert you about a low
tire pressure condition but it does not replace
normal tire maintenance. SeeTire Inspection and
Rotation on page 467andTires on page 454.
Notice:Do not use a tire sealant if your
vehicle has Tire Pressure Monitors. The liquid
sealant can damage the tire pressure monitor
sensors.
Resetting the TPMS Identication Codes
Each TPMS sensor has a unique identication
code. Any time you rotate your vehicle’s tires or
replace one or more of the TPMS sensors,
the identication codes will need to be matched to
the new tire/wheel position. The sensors are
matched to the tire/wheel positions in the following
order: driver’s side front tire, passengers side
front tire, passengers side rear tire, and driver’s
side rear tire using a TPMS diagnostic tool.
See your GM dealer for service.
The TPMS sensors may also be matched to each
tire/wheel position by increasing or decreasing
the tire’s air pressure. If increasing the tire’s
air pressure, do not exceed the maximum ination
pressure indicated on the tire’s sidewall.You will have two minutes to match the rst
tire/wheel position, and ve minutes overall to
match all four tire/wheel positions. If it takes longer
than two minutes, to match the rst tire and
wheel, or more than ve minutes to match all four
tire and wheel positions the matching process
stops and you will need to start over.
The TPMS sensor matching process is outlined
below:
1. Set the parking brake.
2. Turn the ignition switch to RUN with the
engine off.
3. Using the DIC, press the vehicle information
button until the PRESS
VTO RELEARN
TIRE POSITIONS message displays.
4. Press the set/reset button. The horn will
sound twice to indicate the TPMS receiver
is ready, and the TIRE LEARNING ACTIVE
message will display.
5. Start with the driver’s side front tire.
