you might have to step on the
accelerator pedal to maintain
the vehicle speed. When going
downhill, you might have to brake or
shift to a lower gear to maintain the
vehicle speed. When the brakes are
applied the cruise control is
disengaged.
Ending Cruise Control
There are three ways to end cruise
control:
.Step lightly on the brake pedal;
when cruise control disengages,
the indicator light will not be lit.
.Press[.
.Press1to turn the cruise
control system off completely.
The cruise control cannot be
resumed.
Erasing Speed Memory
The cruise control set speed
is erased from memory by
pressing
1or if the vehicle is
turned off.
Object Detection
Systems
Ultrasonic Parking Assist
For vehicles with the Ultrasonic
Rear Parking Assist (URPA) system,
it 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
detect objects up to 2.5 m (8 ft)
behind the vehicle, and at least
20 cm (8 in) off the ground.
{WARNING
The URPA system does not
detect children, pedestrians,
bicyclists, animals, or objects
below the bumper or that are too
close or too far from the vehicle.
It is not available at speeds
greater than 8 km/h (5 mph). To
prevent injury, death, or vehicle

WARNING (Continued)
damage, even with URPA, always
check the area around 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.

9-40 Driving and Operating
To be detected, objects must be at
least 20 cm (8 in) off the ground and
below trunk level. Objects must also
be within 2.5 m (8 ft) from the rear
bumper. The distance objects can
be detected may be less during
warmer or humid weather.
Turning the System On and Off
The URPA system can be turned
on and off using the infotainment
system controls. SeeVehicle
Personalization on page 5‑30.
When the system is off, PARK
ASSIST OFF displays on the Driver
Information Center (DIC). The
message disappears after a short
period of time.
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 PARKING ASSIST: If
this message occurs, check 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 10‑71.
.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.
If the above conditions do not exist,
take the vehicle to your dealer to
repair the system. PARK ASSIST OFF:
If the URPA
system does not activate due to a
temporary condition, the message
displays on the DIC. This can occur
under the following conditions:
.The driver has disabled the
system.
.An object was hanging out of the
trunk during the last drive cycle.
Once the object is removed,
URPA will return to normal
operation.
.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.

10-46 Vehicle Care
.Operating electronic devices or
being near facilities using radio
wave frequencies similar to the
TPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning
properly, it cannot detect or signal a
low tire condition. See your dealer
for service if the TPMS malfunction
light and DIC message, if equipped,
come on and stay on.
TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code needs to be matched to a new
tire/wheel position after rotating the
vehicle’s tires or replacing one or
more of the TPMS sensors. Also,
the TPMS sensor matching process
should be performed after replacing
a spare tire with a road tire
containing the TPMS sensor. The
malfunction light and the DIC
message, if equipped, should
go off at the next ignition cycle.
The sensors are matched to the tire/wheel positions, using a TPMS
relearn tool, in the following order:
driver side front tire, passenger side
front tire, passenger side rear tire,
and driver side rear tire. See your
dealer for service or to purchase a
relearn tool.
There are two minutes to match
the first tire/wheel position, and
five minutes overall to match all
four tire/wheel positions. If it takes
longer, the matching process stops
and must be restarted.
The TPMS sensor matching
process is:
1. Set the parking brake.
2. Turn the ignition to ON/RUN with
the engine off.
3. Use the MENU button to select the Vehicle Information Menu
in the Driver Information
Center (DIC).
4. Use the thumbwheel to scroll to the Tire Pressure Menu Item
screen. 5. Press and hold the SET/CLR
button to begin the sensor
matching process.
A message requesting
acceptance of the process
may display.
6. If requested, press the SET/CLR button again to confirm the
selection.
The horn sounds twice to signal
the receiver is in relearn mode
and the TIRE LEARNING
ACTIVE message displays on
the DIC screen.
7. Start with the driver side front tire.
8. Place the relearn tool against the tire sidewall, near the valve
stem. Then press the button to
activate the TPMS sensor.
A horn chirp confirms that the
sensor identification code has
been matched to this tire and
wheel position.

10-54 Vehicle Care
Wheel Replacement
Replace any wheel that is bent,
cracked, or badly rusted or
corroded. If wheel nuts keep coming
loose, the wheel, wheel bolts, and
wheel nuts should be replaced.
If the wheel leaks air, replace it.
Some aluminum wheels can be
repaired. See your dealer if any of
these conditions exist.
Your dealer will know the kind of
wheel that is needed.
Each new wheel should have the
same load-carrying capacity,
diameter, width, offset, and be
mounted the same way as the one it
replaces.Replace wheels, wheel bolts, wheel
nuts, or Tire Pressure Monitor
System (TPMS) sensors with new
GM original equipment parts.
{WARNING
Using the wrong replacement
wheels, wheel bolts, or wheel
nuts can be dangerous. It could
affect the braking and handling of
the vehicle. Tires can lose air,
and cause loss of control, causing
a crash. Always use the correct
wheel, wheel bolts, and wheel
nuts for replacement.
Notice:
The wrong wheel can
also cause problems with bearing
life, brake cooling, speedometer
or odometer calibration,
headlamp aim, bumper height,
vehicle ground clearance, and tire
or tire chain clearance to the
body and chassis.
Used Replacement Wheels
{WARNING
Replacing a wheel with a used
one is dangerous. How it has
been used or how far it has been
driven may be unknown. It could
fail suddenly and cause a crash.
When replacing wheels, use a
new GM original equipment
wheel.
