9-18 Driving and Operating
Driving on Wet Roads
Rain and wet roads can reduce
vehicle traction and affect your
ability to stop and accelerate.
Always drive slower in these types
of driving conditions and avoid
driving through large puddles and
deep‐standing or flowing water.
{WARNING
Wet brakes can cause crashes.
They might not work as well in a
quick stop and could cause
pulling to one side. You could
lose control of the vehicle.
After driving through a large
puddle of water or a car/vehicle
wash, lightly apply the brake
pedal until the brakes work
normally.(Continued)
WARNING (Continued)
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause your
vehicle to be carried away. If this
happens, you and other vehicle
occupants could drown. Do not
ignore police warnings and be
very cautious about trying to drive
through flowing water.
Hydroplaning
Hydroplaning is dangerous. Water
can build up under your vehicle's
tires so they actually ride on the
water. This can happen if the road is
wet enough and you are going fast
enough. When your vehicle is
hydroplaning, it has little or no
contact with the road.
There is no hard and fast rule about
hydroplaning. The best advice is to
slow down when the road is wet.
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
.Pass with caution.
.Keep windshield wiping
equipment in good shape.
.Keep the windshield washer fluid
reservoir filled.
.Have good tires with proper
tread depth. SeeTireson
page 10‑43.
.Turn off cruise control.
Highway Hypnosis
Always be alert and pay attention to
your surroundings while driving.
If you become tired or sleepy, find a
safe place to park your vehicle
and rest.
Other driving tips include:
.Keep the vehicle well ventilated.
.Keep interior temperature cool.

Winter Driving
Driving on Snow or Ice
Drive carefully when there is snow
or ice between the tires and the
road, creating less traction or grip.
Wet ice can occur at about 0°C
(32°F) when freezing rain begins to
fall, resulting in even less traction.
Avoid driving on wet ice or in
freezing rain until roads can be
treated with salt or sand.
Drive with caution, whatever the
condition. Accelerate gently so
traction is not lost. Accelerating too
quickly causes the wheels to spin
and makes the surface under the
tires slick, so there is even less
traction.Try not to break the fragile traction.
If you accelerate too fast, the drive
wheels will spin and polish the
surface under the tires even more.
The
Antilock Brake System (ABS)
on page 9‑38improves vehicle
stability during hard stops on
slippery roads, but apply the brakes
sooner than when on dry pavement.
Allow greater following distance on
any slippery road and watch for
slippery spots. Icy patches can
occur on otherwise clear roads in
shaded areas. The surface of a
curve or an overpass can remain icy
when the surrounding roads are
clear. Avoid sudden steering
maneuvers and braking while
on ice.
Turn off cruise control, if equipped,
on slippery surfaces.
Blizzard Conditions
Being stuck in snow can be in a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use the Roadside
Assistance Program
on page 13‑6.
To get help and keep everyone in
the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.

Ride Control Systems
Traction Control
System (TCS)
The vehicle has a Traction Control
System (TCS) that limits wheel spin.
This is especially useful in slippery
road conditions. The system
operates only if it senses that any of
the drive wheels are spinning or
beginning to lose traction. When this
happens, TCS applies the brakes to
limit wheel spin and also reduces
engine power. The system may be
heard or felt while it is working, but
this is normal.This light will flash when TCS is
limiting wheel spin.
It is recommended to leave the
system on for normal driving
conditions, but it may be necessary
to turn the system off if the vehicle
is stuck in sand, mud, ice, or snow,
and you want to“rock”the vehicle to
attempt to free it. See If the Vehicle
is Stuck
on page 9‑22for more
information.
The TCS/StabiliTrak button is
located on the instrument panel.
Press and release this button to turn
off TCS. The TCS warning light will
be displayed on the instrument
panel cluster. The traction control
system can be turned back on by
pressing the TCS/StabiliTrak button.
If the system is limiting wheel spin
when the button is pressed, the
system will not turn off until there is
no longer a current need to limit
wheel spin. The system can be
turned back on at any time by
pressing the button again. If the
TCS light does not come on, TCS
may not be functioning properly and
the vehicle should be serviced at
your dealer/retailer.

Adding non‐dealer/non‐retailer
accessories can affect the vehicle's
performance. SeeAccessories and
Modifications
on page 10‑3for
more information.
StabiliTrak System
The vehicle has a stability control
system called StabiliTrak which
combines antilock brake, traction
and stability control systems and
helps the driver maintain directional
control of the vehicle in most driving
conditions.
StabiliTrak activates when the
computer senses a diifference
between the intended path and the
direction the vehicle is actually
traveling. StabiliTrak selectively
applies braking pressure at any one
of the vehicle's brakes to assist the
driver with keeping the vehicle on
the intended path.
When the vehicle is started and
begins to move, the system
performs several diagnostic checks
to insure there are no problems. The system may be heard or felt
while it is working. This is normal
and does not mean there is a
problem with the vehicle.
This light is located on the
instrument panel cluster.
It will flash when StabiliTrak is both
on and activated.
If the system fails to turn on or
activate, this light will be on solid.
When the light is on solid, the
system will not assist the driver
maintain directional control of the
vehicle. Adjust your driving
accordingly.
The StabiliTrak system
automatically comes on whenever
the vehicle is started. To assist the
driver with vehicle directional
control, especially in slippery road
conditions, the system should
always be left on. StabiliTrak can be
turned off if needed.The Traction Control System (TCS)/
StabiliTrak button is located on the
instrument panel.
TCS can be turned off or turned on
by pressing and releasing the TCS/
StabiliTrak button. To disable both
StabiliTrak and TCS, press and hold
the button until the TCS/StabiliTrak
warning light turns on solid.
It is recommended to leave the
system on for normal driving
conditions, but it may be necessary
to turn the system off if the vehicle
is stuck in sand, mud, ice or snow,
and you want to
“rock”the vehicle to
attempt to free it.
ProCarManuals.com
9-42 Driving and Operating
StabiliTrak may also turn off
automatically if it determines that a
problem exists with the system. The
TCS/StabiliTrak warning light will be
on solid to warn the driver that
StabiliTrak is disabled and requires
service. If the problem does not
clear itself after restarting the
vehicle, see your dealer/retailer for
service.
If cruise control is being used when
StabiliTrak activates, the cruise
control automatically disengages.
The cruise control can be
re-engaged when road conditions
allow. SeeCruise Control
on
page 9‑42.
Cruise Control
With cruise control, the vehicle can
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below 40 km/h (25 mph).
On vehicles with the StabiliTrak
®
feature, the system may begin to
limit wheel spin while you are using
cruise control. If this happens, the
cruise control will automatically
disengage. See StabiliTrak System
on page 9‑41.
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
(Continued)
WARNING (Continued)
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
Setting Cruise Control
{WARNING
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.

Vehicle Care 10-59
The vehicle needs new tires if any
of the following statements are true:
.You can see the indicators at
three or more places around
the tire.
.You can see cord or fabric
showing through the tire's
rubber.
.The tread or sidewall is cracked,
cut, or snagged deep enough to
show cord or fabric.
.The tire has a bump, bulge,
or split.
.The tire has a puncture, cut,
or other damage that cannot be
repaired well because of the size
or location of the damage.
The rubber in tires degrades over
time. This is also true for the
spare tire, if the vehicle has one,
even if it is not being used.
Multiple conditions affect how fast
this aging takes place, including temperatures, loading conditions,
and inflation pressure maintenance.
With proper care and maintenance
tires typically wear out before they
degrade due to age. If you are
unsure about the need to replace
the tires as they get older, consult
the tire manufacturer for more
information.
Buying New Tires
GM has developed and matched
specific tires for your vehicle.
The original equipment tires
installed on your vehicle,
when it was new, were
designed to meet General
Motors Tire Performance Criteria
Specification (TPC Spec)
system rating. If you need
replacement tires, GM strongly
recommends that you get tires
with the same TPC Spec rating.
This way, your vehicle will
continue to have tires that are
designed to give the same
performance and vehicle safety,
during normal use, as the
original tires.
GM's exclusive TPC Spec
system considers over a dozen
critical specifications that impact
the overall performance of
your vehicle, including brake
system performance, ride and
handling, traction control, and
tire pressure monitoring
performance. GM's TPC Spec
number is molded onto the tire's
sidewall near the tire size. If the
tires have an all‐season tread
design, the TPC Spec number
will be followed by an MS for
mud and snow. See
Tire
Sidewall Labeling
on page 10‑44
for additional information.
ProCarManuals.com
Vehicle Care 10-61
Vehicles that have a tire
pressure monitoring system
could give an inaccurate
low‐pressure warning if non‐TPC
Spec rated tires are installed
on your vehicle. Non‐TPC
Spec rated tires may give a
low‐pressure warning that is
higher or lower than the proper
warning level you would get with
TPC Spec rated tires. SeeTire
Pressure Monitor System
on
page 10‑52
.
Your vehicle's original
equipment tires are listed on the
Tire and Loading Information
Label. See Vehicle Load Limits
on page 9‑22, for more
information about the Tire and
Loading Information Label and
its location on your vehicle.
Different Size Tires and
Wheels
If you add wheels or tires that are a
different size than your original
equipment wheels and tires, this
may affect the way your vehicle
performs, including its braking, ride
and handling characteristics,
stability, and resistance to rollover.
Additionally, if your vehicle has
electronic systems such as,
anti‐lock brakes, rollover airbags,
traction control, and stability control,
the performance of these systems
can be affected.
{WARNING
If you add different sized
wheels, your vehicle may not
provide an acceptable level of
performance and safety if tires not
recommended for those wheels
are selected. You may increase
the chance that you will crash and
suffer serious injury. Only use
Saturn specific wheel and tire
systems developed for your
vehicle, and have them properly
installed by a Saturn certified
technician.
