Using Cruise Control on Hills
How well the cruise control will work on hills depends
upon the vehicle’s speed, its load, and the steepness of
the hills. When going up steep hills, the accelerator pedal
might have to be used in order to maintain the vehicle’s
speed. When going downhill, the brakes might have to be
applied, or the transaxle might have to be shifted to a
lower gear to keep the vehicle’s speed down. Doing
either of these things will take the vehicle out of cruise.
It may be better not to use the cruise control if the brakes
constantly have to be applied, or the vehicle continuously
needs to be shifted to a lower gear.
Cancelling Cruise Control
To cancel a cruise control session, pull the cruise
control lever forward, or step lightly on the brake pedal.
Doing either of these things will only end the current
cruise control session, but the set speed will be retained
in memory.
Push the button at the end of the cruise control lever to
turn the system off.
Erasing Speed Memory
When the cruise control or the ignition is turned off,
the cruise control set speed memory is erased.
Exterior Lamps
The control to the left of
the steering column
operates the exterior
lamps.
9(Off):Turn the control to this position to toggle off
all lamps. This is a momentary control that will spring
back to AUTO when released.
This momentary control will turn the automatic
headlamps and/or the Daytime Running Lamps on and
off for U.S. vehicles. For vehicles rst sold in Canada,
this is only true when the transaxle is in PARK (P).
AUTO (Automatic):Turn the control to this position to
set your headlamps in automatic mode. AUTO mode,
if enabled, will turn the exterior lamps on and off
automatically depending on how much light is available
outside the vehicle.

How the System Works
Unless disabled, the URPA will turn on automatically
when the shift lever is moved into REVERSE (R). When
the system turns on, the three lights on the display
will illuminate for one and a half seconds to let you know
that the system is working. If your vehicle is moving in
REVERSE (R) at a speed greater than 3 mph (5 km/h),
the red light will ash to remind you that the system
does not work at speed greater than 3 mph (5 km/h).
If an object is detected at a REVERSE (R) speed of less
than 3 mph (5 km/h), one of the following will occur:
Description English Metric
amber light 5 ft 1.5 m
amber/amber lights 40 in 1.0 m
amber/amber/red lights &
continuous chime20 in 0.5 m
amber/amber/red lights
ashing & continuous
chime1 ft 0.3 m
A chime will sound the rst time an object is detected
between 20 inches (0.5 m) and 5 feet (1.5 m) away.URPA cannot detect objects that are above liftgate
level. In order for the rear sensors to recognize
an object, it must be within detection range behind the
vehicle.
When the System Does Not Seem to Work
Properly
The light may ash red when the vehicle is in
REVERSE (R) if the ultrasonic sensors are not kept
clean. So be sure to keep your rear bumper free of mud,
dirt, snow, ice and slush. Other conditions that may
affect system performance include things like the
vibrations from a jackhammer or the compression of air
brakes on a very large truck. If after cleaning the
rear bumper and then driving forward at least 15 mph
(25 km/h), the display continues to ash red, see
your dealer.
If a trailer was attached to your vehicle, or a bicycle or
an object was on the back of, or hanging out of your
liftgate during your last drive cycle, the light may
also ash red. The light will continue to ash whenever
in REVERSE (R) until your vehicle is driven forward
at least 15 mph (25 km/h) without any obstructions
behind the vehicle.

Charging System Light
The charging system light
will come on briey when
you turn on the ignition,
but the engine is not
running, as a check to
show you it is working.
It should go out once the engine is running. If it stays
on, or comes on while you are driving, you may have
a problem with the charging system. It could indicate
that you have problems with a generator drive belt,
or another electrical problem. Have it checked
right away. Driving while this light is on could drain
your battery.
If you must drive a short distance with the light on,
be certain to turn off all your accessories, such as the
radio and air conditioner.
Brake System Warning Light
When the ignition is on, the brake system warning light
will come on when you set your parking brake. The
light will stay on if your parking brake doesn’t release
fully. If it stays on after your parking brake is fully
released, it means you have a brake problem.
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can
still work and stop you. For good braking, though,
you need both parts working well.
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
This light should come on briey when you turn the
ignition key to RUN. If it doesn’t come on then, have it
xed so it will be ready to warn you if there’s a problem.

If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the
oor. It may take longer to stop. If the light is still on,
have the vehicle towed for service. SeeAnti-Lock Brake
System Warning Light on page 3-38andTowing Your
Vehicle on page 4-37.
{CAUTION:
Your brake system may not be working
properly if the brake system warning light is
on. Driving with the brake system warning
light on can lead to an accident. If the light
is still on after you have pulled off the road
and stopped carefully, have the vehicle towed
for service.
Anti-Lock Brake System Warning
Light
Your vehicle may have
this light. If it does, the
anti-lock brake system
warning light should come
on for a few seconds
when you turn the ignition
key to RUN.
If the anti-lock brake system warning light stays on
longer than normal after you’ve started your engine, turn
the ignition off. Or, if the light comes on and stays on
when you’re driving, stop as soon as possible and turn
the ignition off. Then start the engine again to reset
the system. If the light still stays on, or comes on again
while you’re driving, the anti-lock brake system needs
service and you don’t have anti-lock brakes.
The anti-lock brake system warning light should come
on briey when you turn the ignition key to RUN. If
the light doesn’t come on then, have it xed so it will be
ready to warn you if there is a problem.

Traction Control System (TCS)
Warning Light
Your vehicle is equipped
with a traction control
system warning light.
The traction control system warning light may come on
for the following reasons:
If you turn the system off by pressing the traction
control button. To turn the system back on, press
the button again. The warning light should go
off. SeeTraction Control System (TCS) on page 4-9
for more information.
If there’s a brake system problem that is specically
related to traction control, the traction control
system will turn off and the warning light will come
on. If your brakes begin to overheat, the traction
control system will turn off and the warning light
will come on until your brakes cool down.
If the traction control system is affected by an
engine-related problem, the system will turn off
and the warning light will come on.If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Engine Coolant Temperature Gage
This gage shows the engine coolant temperature.
If the red gage lamp turns on, your engine is too hot!
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull off the road, stop your
vehicle and turn off the engine as soon as possible.
SeeEngine Overheating on page 5-24.

This message will continue to display for two seconds
if it has not been acknowledged when the engine is
turned off. It will also re-display for two seconds if the
message has been acknowledged, but the condition still
exists when the engine is turned off.
If the condition still exists, the message will re-appear
when the engine is turned on. If this message continues
to appear, have the system repaired by your GM
dealer as soon as possible to avoid damage to your
engine.
ALL WHEEL DRIVE DISABLED
If your vehicle has the all-wheel drive system, this
message will display when there is a spare tire on the
vehicle, or when the anti-lock brake system warning
light comes on, or when the rear differential uid
is overheating. This message will turn off when the
differential uid cools.
The all-wheel drive system will be disabled until the
compact spare tire is replaced by a full-size tire. If the
warning message is still on after putting on the full-size
tire, you need to reset the warning message. To
reset the warning message, turn the ignition off and
then back on again. If the message stays on, see your
GM dealer right away. SeeAll-Wheel Drive (AWD)

BATTERY SAVER ACTIVE
This message will display when the system detects that
the battery voltage is dropping beyond a reasonable
level. The battery saver system will start reducing certain
features of the vehicle that you may be able to notice.
At the point that the features are disabled, this message
is displayed. It means that the vehicle is trying to
save the charge in the battery.
Turn off all unnecessary accessories to allow the battery
to recharge.
The normal battery voltage range is 11.5 to 15.5 volts.
You can monitor the battery voltage by pressing the
information button until BATTERY displays.
CHANGE OIL SOON
This message will display when service is required for
the vehicle. See your GM dealer. SeeEngine Oil
