Windshield Washer
L(Washer Fluid):There is a paddle marked with the
windshield washer symbol at the top of the multifunction
lever. To spray washer uid on the windshield, push
the paddle. The wipers will clear the window and then
either stop or return to your preset speed.
{CAUTION:
In freezing weather, do not use your washer
until the windshield is warmed. Otherwise the
washer uid can form ice on the windshield,
blocking your vision.
Cruise Control
If your vehicle has cruise control, you can maintain a
speed of about 25 mph (40 km/h) or more without
keeping your foot on the accelerator. This can really
help on long trips. Cruise control does not work at
speeds below about 25 mph (40 km/h).
If you apply your brakes, the cruise control will
disengage.
{CAUTION:
Cruise control can be dangerous where you
cannot drive safely at a steady speed. So, do
not use your cruise control on winding roads
or in heavy traffic.
Cruise control can be dangerous on slippery
roads. On such roads, fast changes in tire
traction can cause needless wheel spinning,
and you could lose control. Do not use cruise
control on slippery roads.

9(Off):This position turns the system off.
R(On):This position activates the system.
S(Resume/Accelerate):Push the lever to this symbol
to make the vehicle accelerate or resume to a
previously set speed.
T(Set):Press this button to set the speed.
Setting Cruise Control
{CAUTION:
If you leave your cruise control on when you
are not using cruise, you might hit a button
and go into cruise when you do not want to.
You could be startled and even lose control.
Keep the cruise control switch off until you
want to use cruise control.
1. Move the cruise control switch to on.
2. Get up to the speed you want.
3. Press in the set button at the end of the lever and
release it.
4. Take your foot off the accelerator pedal.
The CRUISE light on the instrument panel will illuminate
when the cruise control is engaged.
3-11

Resuming a Set Speed
Suppose you set your cruise control at a desired speed
and then you apply the brake. This, of course,
disengages the cruise control. But you don’t need to
reset it.
Once you’re going about 25 mph (40 km/h) or more,
you can move the cruise control switch from on to
resume/accelerate briey.
You’ll go right back up to your chosen speed and
stay there.
If you hold the switch at resume/accelerate briey, the
vehicle will keep going faster until you release the switch
or apply the brake. So unless you want to go faster,
don’t hold the switch at resume/accelerate.
Increasing Speed While Using Cruise
Control
There are two ways to go to a higher speed:
Use the accelerator pedal to get to the higher
speed. Press the set button at the end of the lever,
then release the button and the accelerator
pedal. You’ll now cruise at the higher speed.
Move the cruise switch from on to
resume/accelerate. Hold it there until you get up to
the speed you want, and then release the switch.
To increase your speed in very small amounts,
move the switch to resume/accelerate briey. Each
time you do this, your vehicle will go about
1 mph (1.6 km/h) faster.
Reducing Speed While Using Cruise
Control
Press and hold the set button at the end of the
lever until you reach the lower speed you want, then
release it.
To slow down in very small amounts, press the set
button briey. Each time you do this, you’ll go
about 1 mph (1.6 km/h) slower.
Passing Another Vehicle While Using
Cruise Control
Use the accelerator pedal to increase your speed.
When you take your foot off the pedal, your vehicle will
slow down to the cruise control speed you set earlier.
3-12

Using Cruise Control on Hills
How well your cruise control will work on hills depends
upon your speed, load and the steepness of the
hills. When going up steep hills, you may want to step
on the accelerator pedal to maintain your speed.
When going downhill, you may have to brake or shift to
a lower gear to keep your speed down. Of course,
applying the brake takes you out of cruise control. Many
drivers nd this to be too much trouble and don’t use
cruise control on steep hills.
Ending Cruise Control
There are three ways to turn off the cruise control:
Step lightly on the brake pedal.
Move the cruise control switch to off.
If your vehicle has the Stabilitrak®feature, cruise
control will deactivate if road conditions cause
Stabilitrak
®to activate.
Erasing Speed Memory
When you turn off the cruise control or the ignition, your
cruise control set speed memory is erased.
Exterior Lamps
The control on the driver’s
side of your instrument
panel operates the
exterior lamps.
The exterior lamp control has four positions:
Ø (Defeat):Turn the control to this position to turn off
the DRL.
i(Daytime Running Lamps (DRL)):Turning the
control to this position selects the DRL. When the
vehicle is shifted out of PARK (P), the instrument panel
lamps will illuminate and the DRL will turn on, unless
defeated. When the DRL are active, the DRL indicator
will illuminate.

Security Light
The light will stay on until the engine starts. If the light
ashes, the Passlock®System has entered a tamper
mode. If the vehicle fails to start, seePasslock®
on page 2-18.
If the light comes on continuously while driving and
stays on, there may be a problem with the Passlock
®
System. Your vehicle will not be protected by Passlock®,
and you should see your GM dealer.
Cruise Control Light
The cruise light comes on whenever you set your
cruise control. SeeCruise Control on page 3-10for
more information. United States

Pressing and holding the
StabiliTrak®button located
on the instrument panel
for more than ve seconds
can turn off StabiliTrak
®
and part of the traction
control system.
For your safety, the system can only be disabled when
the vehicle speed is less than 20 mph (32 km/h).
You will hear three chimes and the StabiliTrak
®not
ready light will come on.
To turn on the StabiliTrak
®system, press the
StabiliTrak®button again. StabiliTrak®will automatically
turn back on when the vehicle speed exceeds 20 mph
(32 km/h). You will hear one chime and the StabiliTrak
®
not ready light will turn off.
When the StabiliTrak
®system has been turned off you
may still hear system noises as a result of the
brake-traction control coming on.It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn
the system off if your vehicle is stuck in sand, mud, ice
or snow, and you want to “rock” your vehicle to
attempt to free it. SeeIf You Are Stuck: In Sand, Mud,
Ice or Snow on page 4-28.
StabiliTrak®System Operation
The StabiliTrak®system is normally on, except when
the system is initializing or has been disabled with
the StabiliTrak
®button. The StabiliTrak®system will
automatically activate to assist the driver in maintaining
vehicle directional control in most driving conditions.
When activated, the StabiliTrak
®system may reduce
engine power to the wheels and apply braking to
individual wheels as necessary to assist the driver with
vehicle directional control. If your vehicle is in cruise
control when the system activates, the StabiliTrak
®
indicator light on the instrument panel will ash, and the
cruise control will automatically disengage. When the
StabiliTrak
®system is no longer active, you may
re-engage the cruise control. SeeCruise Control on
page 3-10.
The StabiliTrak
®system may also turn off automatically
if it determines that a problem exists with the system.
If the problem does not clear itself after restarting
the vehicle, you should see your dealer for service.
