brake sensor CHEVROLET TRAVERSE 2009 1.G Owners Manual

When the System Does Not
Seem to Work Properly
If the URPA system does not
activate due to a temporary
condition, the message PARK
ASSIST OFF displays 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 may occur under the following
conditions:
The driver disables the system.
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 5-81.
A trailer was attached to the
vehicle, or a bicycle or an object
was hanging out of the liftgate
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.
Rear Vision
Camera (RVC)
The vehicle may have a Rear Vision
Camera system. Read this entire
section before using it.
{CAUTION
The Rear Vision Camera (RVC)
system does not replace driver
vision. RVC does not:
Detect objects that are
outside the camera’s eld of
view, below the bumper, or
underneath the vehicle.
Detect children, pedestrians,
bicyclists, or pets.
Do not back the vehicle by only
looking at the rear vision camera
screen, or use the screen during
longer, higher speed backing
maneuvers or where there could
be cross-traffic. Your judged
distances using the screen will
differ from actual distances.

2-38 Features and Controls

The TPMS sensor matching process
is outlined below:
1. Set the parking brake.
2. Turn the ignition switch to
ON/RUN with the engine off.
3. Press the Remote Keyless
Entry (RKE) transmitter’s LOCK
and UNLOCK buttons at the
same time for approximately
ve seconds. The horn sounds
twice to signal the receiver
is in relearn mode and TIRE
LEARNING ACTIVE message
displays on the DIC screen.
4. Start with the driver side front tire.
5. Remove the valve cap from the
valve cap stem. Activate the
TPMS sensor by increasing or
decreasing the tire’s air pressure
for ve seconds, or until a horn
chirp sounds. The horn chirp,
which may take up to 30 seconds
to sound, conrms that the sensor
identication code has been
matched to this tire and wheel
position.6. Proceed to the passenger side
front tire, and repeat the
procedure in Step 5.
7. Proceed to the passenger side
rear tire, and repeat the
procedure in Step 5.
8. Proceed to the driver side rear
tire, and repeat the procedure
in Step 5. The horn sounds
two times to indicate the sensor
identication code has been
matched to the driver side rear
tire, and the TPMS sensor
matching process is no longer
active. The TIRE LEARNING
ACTIVE message on the
DIC display screen goes off.
9. Turn the ignition switch to
LOCK/OFF.
10. Set all four tires to the
recommended air pressure level
as indicated on the Tire and
Loading Information label.
11. Put the valve caps back on the
valve stems.Tire Inspection and
Rotation
We recommend that you
regularly inspect the vehicle’s
tires, including the spare tire, if
the vehicle has one, for signs of
wear or damage. SeeWhen It Is
Time for New Tires on page 5-50
for more information.
Tires should be rotated
every 5,000 to 8,000 miles
(8 000 to 13 000 km). See
Scheduled Maintenance on
page 6-3.
The purpose of a regular tire
rotation is to achieve a uniform
wear for all tires on the vehicle.
This will ensure that the vehicle
continues to perform most like it
did when the tires were new.
