Windshield Wipers
The lever on the right side of the steering column
operates the windshield wipers.
7(Mist):Pull the lever down and release it for a
single wiping cycle. The lever will return to its original
position. For more cycles, hold the lever down before
releasing it.
9(Off):Put the lever in this position to turn off the
wipers.
&(Delay):Put the lever in this position to set a delay
between wipes. Turn the delay adjustment band to
set the length of the delay.
x(Delay Adjustment):Use this band to set the
length of the delay between wipes when using the delay
feature. The closer you move the band toward mist,
the longer the delay. The windshield wiper lever must be
in delay for this feature to work.
6(Low Speed):Put the lever in this position for
slow, steady wiping cycles.
1(High Speed):Put the lever in this position for
rapid wiping cycles.
If the windshield wipers are in use for about six seconds
while you are driving, the exterior lamps will come on
automatically if the exterior lamp control is in AUTO. See
Wiper Activated Headlamps on page 3-16for more
information.
Be sure to clear ice and snow from the wiper blades
before using them. If they’re frozen to the windshield,
gently loosen or thaw them. If the blades do become
damaged, install new blades or blade inserts. For more
information, seeWindshield Wiper Blade Replacement
on page 5-49.
Heavy snow or ice can overload the wiper motor. A
circuit breaker will stop the motor until it cools down.
Clear away snow or ice to prevent an overload.

Sensors
There is a solar sensor located on the instrument panel,
near the windshield.There is also an interior
temperature sensor
located to the right of the
steering wheel on the
instrument panel.
These sensors monitor the solar radiation and the air
inside your vehicle, then use the information to maintain
the selected temperature by initiating needed
adjustments to the temperature, the fan speed and the
air delivery system. The system may also supply
cooler air to the side of the vehicle facing the sun. The
recirculation mode will also be activated, as necessary.
Do not cover the sensors or the automatic climate
control system will not work properly.

Service Steering System
Your vehicle may be equipped with a speed variable
assist steering system. SeeSteering on page 4-12.
The Service Steering System message will be displayed
if a problem is detected with the speed variable assist
steering system. When this message is displayed,
you may notice that the effort required to steer
the vehicle increases or feels “heavier,” but you will still
be able to steer the vehicle.
Service Suspension System
This message is displayed to indicate that the
suspension system is not operating properly. Have your
vehicle serviced at your GM dealer.
Service Theft System
This message means there is a problem with the
immobilizer. SeeImmobilizer on page 2-18for more
information. A fault has been detected in the system
which means that the system is disabled and is
not protecting the vehicle. The vehicle usually restarts,
however, you may want to take your vehicle to your
GM dealer before turning off the engine.
Service Tire Monitor System
This message will appear if the Tire Pressure Monitor
(TPM) system is not working properly. Have your vehicle
serviced at your GM dealer as soon as possible. See
Tire Pressure Monitor System on page 5-61for
more information.

related powertrain malfunction occurs. Have your vehicle
serviced at your GM dealer as soon as possible.
Speed Limited to XXX
This message indicates that your vehicle speed is
limited to XXX (mph in English mode and km/h in Metric
mode) because the vehicle detects a problem in the
suspension system. Have your vehicle serviced at your
GM dealer.

Control of a Vehicle
You have three systems that make your vehicle go where
you want it to go. They are the brakes, the steering, and
the accelerator. All three systems have to do their work at
the places where the tires meet the road.
Sometimes, as when you are driving on snow or ice, it
is easy to ask more of those control systems than
the tires and road can provide. That means you can lose
control of your vehicle. SeeStabiliTrak
®System on
page 4-11.
Braking
Braking action involves perception time and
reaction time.
First, you have to decide to push on the brake pedal.
That is perception time. Then you have to bring up your
foot and do it. That is reaction time.
Average reaction time is about three-fourths of a
second. But that is only an average. It might be less
with one driver and as long as two or three seconds or
more with another. Age, physical condition, alertness,
coordination, and eyesight all play a part. So do alcohol,
drugs, and frustration. But even in three-fourths of a
second, a vehicle moving at 60 mph (100 km/h) travels66 feet (20 m). That could be a lot of distance in an
emergency, so keeping enough space between
your vehicle and others is important.
And, of course, actual stopping distances vary greatly
with the surface of the road, whether it is pavement
or gravel; the condition of the road, whether it is
wet, dry, or icy; tire tread; the condition of your brakes;
the weight of the vehicle; and the amount of brake
force applied.
Avoid needless heavy braking. Some people drive in
spurts — heavy acceleration followed by heavy
braking — rather than keeping pace with traffic. This is a
mistake. Your brakes may not have time to cool between
hard stops. Your brakes will wear out much faster if you
do a lot of heavy braking. If you keep pace with the traffic
and allow realistic following distances, you will eliminate a
lot of unnecessary braking. That means better braking
and longer brake life.
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.
4-6
The anti-lock system can change the brake pressure
faster than any driver could. The computer is
programmed to make the most of available tire and road
conditions. This can help you steer around the obstacle
while braking hard.
As you brake, your computer keeps receiving updates on
wheel speed and controls braking pressure accordingly.Remember: Anti-lock does not change the time you
need to get your foot up to the brake pedal or always
decrease stopping distance. If you get too close to
the vehicle in front of you, you will not have time to apply
your brakes if that vehicle suddenly slows or stops.
Always leave enough room up ahead to stop, even
though you have anti-lock brakes.
Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down rmly and let anti-lock work for you. You may feel
the brakes vibrate, or you may notice some noise,
but this is normal.
Braking in Emergencies
With anti-lock brakes, you can steer and brake at the
same time. In many emergencies, steering can help you
more than even the very best braking.
