How the System Works when Backing
If the shift lever is in REVERSE (R), URPA detects
objects close to the rear bumper. The rst time an object
is detected a single beep will sound. If an object is
detected at a REVERSE (R) speed between 0 mph
(0 km/h) and 5 mph (8 km/h), the following describes
what will occur based on your distance to a detected
object located behind the vehicle:
At distances between 40 inches (1 m) and
8 ft (2.5 m), a single amber light will be lit.
At distances between 23 inches (0.6 m) and
40 inches (1 m), both amber lights will be lit.
At distances between 12 inches (0.3 m) and
23 inches (0.6 m), all three lights (amber/amber/red)
will be lit.
At distances less than 12 inches (0.3 m), a beeping
sound will repeat for a short time and all three lights
(amber/amber/red) will be lit and ashing.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a temporary
condition, the message PARK 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
REVERSE (R). This occurs under the following conditions:
The driver disables the system. SeeDIC Controls
and Displays on page 3-50.
The parking brake pedal is depressed.
A trailer was attached to your vehicle, or a bicycle
or an object was hanging out of your trunk during
your last drive when you turned off the vehicle.
If the attached objects are removed from your
vehicle before the start of your next drive,
the system will return to normal operation unless
an object is detected when the vehicle is shifted into
REVERSE (R). If this occurs, URPA assumes the
object is still attached, so you will have to wait until
the vehicle is driven forward above 15 mph (25 km/h)
before URPA will return to normal operation.
3-20

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 5-87. If the DIC
still displays the PARK 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 using the
Driver Information Center (DIC), the PARK ASSIST
ON option will not be selectable if the necessary
conditions stated above for normal system operation
are not met.
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 3-56.
If the bumper is damaged, your URPA system may
not work properly. Take the vehicle to your dealer
to repair the system.
Accessory Power Outlet(s)
The accessory power outlets can be used to plug in
electrical equipment such as a cellular telephone or
CB radio.
Your vehicle has two power outlets. One is located next
to the ashtray and the other is located on the right
forward lower edge of the driver’s seat.
Your vehicle may have a small cap that must be pulled
down to access the accessory power outlet. If it does,
when not using the outlet be sure to cover it with
the protective cap.
Notice:Leaving electrical equipment on for
extended periods will drain the battery. Always turn
off electrical equipment when not in use and do
not plug in equipment that exceeds the maximum
amperage rating.
Certain electrical accessories may not be compatible to
the accessory power outlets and could result in blown
vehicle or adapter fuses. If you experience a problem
see your dealer for additional information on the
accessory power outlets.

Section 4 Driving Your Vehicle

If your engine ever stops while you are driving, brake
normally but do not pump your brakes. If you do,
the pedal may get harder to push down. If your engine
stops, you will still have some power brake assist.
But you will use it when you brake. Once the power
assist is used up, it may take longer to stop and
the brake pedal will be harder to push.
Adding non-GM accessories can affect your vehicle’s
performance. SeeAccessories and Modications
on page 5-3.
Anti-Lock Brake System (ABS)
Your vehicle has the Anti-Lock Brake System (ABS),
an advanced electronic braking system that will
help prevent a braking skid.
When you start your engine and begin to drive away,
ABS will check itself. You may hear a momentary
motor or clicking noise while this test is going on, and
you may even notice that your brake pedal moves
a little. This is normal.
If there is a problem with
ABS, this warning light
will stay on. SeeAnti-Lock
Brake System Warning
Light on page 3-41.Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each front wheel
and at both rear wheels.
4-7

StabiliTrak®System
Your vehicle may have this feature. The StabiliTrak®
system is an advanced computer controlled system that
helps the driver maintain directional control of the
vehicle in difficult driving conditions. This is
accomplished by selectively applying any one of the
vehicle’s brakes and reducing engine power. The
StabiliTrak
®system comes on automatically whenever
you start your vehicle. The system cannot be turned off.
The STABILITRAK NOT READY message may be
displayed in the DIC and the traction control system and
StabiliTrak
®warning light on the instrument panel
cluster will be on after rst driving the vehicle and
exceeding 30 mph 48 (km/h) for 30 seconds. The
StabiliTrak
®system is off until the light has turned off.
This could take up to 15 minutes.
The traction control system and StabiliTrak
®warning light
on the instrument panel cluster will ash when the system
is operating. SeeTraction Control System (TCS) Warning
Light on page 3-41,StabiliTrak
®Indicator Light on
page 3-42andDIC Warnings and Messages on
page 3-56for more information. You may also feel or
hear the system working. This is normal.The SERVICE STABILITRAK message will be displayed
and the traction control system and StabiliTrak
®warning
light on the instrument panel cluster will come on if there
is a problem with the system. When this light and the
SERVICE STABILITRAK message are on, the system is
not operational. Adjust your driving accordingly.
Panic Brake Assist
Your vehicle may have a panic brake assist system that
monitors the intention of the driver while braking. If
the system senses that the driver has applied hard/fast
pressure to the brake pedal, the system will generate
additional pressure, making it easier for the driver
to maintain brake application. When this happens the
brake pedal will feel easier to push. Just hold the brake
pedal down rmly and let the system work for you.
You may feel the brakes vibrate, or you may notice
some noise but this is normal. The brakes will return
to normal operation after the brake pedal has
been released.
