The vehicle may straighten out.Be ready for a second skid if itoccurs.
.Slow down and adjust yourdriving according to weatherconditions. Stopping distancecan be longer and vehiclecontrol can be affected whentraction is reduced by water,snow, ice, gravel, or othermaterial on the road. Learn torecognize warning clues—suchas enough water, ice, or packedsnow on the road to make amirrored surface—and slowdown when you have any doubt.
.Try to avoid sudden steering,acceleration, or braking,including reducing vehicle speedby shifting to a lower gear. Anysudden changes could causethe tires to slide.
Remember: Antilock brakes helpavoid only the braking skid.
Track Events and
Competitive Driving
{Danger
High-performance features are
intended for use only on closed
tracks by experienced and
qualified drivers and should not
be used on public roads.
High-speed driving, aggressive
cornering, hard braking, and other
high-performance driving can be
dangerous. Improper driver inputs
for the conditions may result in
loss of control of the vehicle,
which could injure or kill you or
others. Always drive safely.
Track events or competitive drivingmay affect the vehicle warranty. Seethe warranty manual before usingthe vehicle for track testing or othercompetitive driving.
Caution
If the vehicle is used for track
events and competitive driving,
the engine may use more oil than
it would with normal use. Low oil
levels can damage the engine.
Check the oil level often and
maintain the proper level. See
Engine Oil0275.
Engine Oil
Be sure to check the oil level oftenduring racing or other competitivedriving and keep the level at or nearthe upper mark that shows theproper operating range on theengine oil dipstick.
For track events or competitivedriving, it is recommended that thebrake fluid be replaced with a highperformance brake fluid that has adry boiling point greater than 279 °C(534 °F). After conversion to thehigh performance brake fluid, followthe brake fluid service

Rear Axle
Axles must have 885 km (500 mi)before being used in track driving
The rear axle fluid temperaturesmay be higher when driving insevere conditions. Drain and refillwith new fluid after the first racing orcompetitive driving event, and thenafter every 24 hours of racing orcompetitive driving. SeeRecommended Fluids andLubricants0358.
Caution
During a first time track or racing
event, high rear axle
temperatures can occur. Damage
could be caused to the rear axle
and would not be covered by the
vehicle warranty. Do not drive as
long or as fast the first time the
vehicle is driven on the track or
raced.
For extended track use, GMrecommends installing a reardifferential cooler to protect therear axle.
Wheel Alignment
For racing and competitive driving,the vehicle load should be limited tothe driver only and no cargo. Thetires should be inflated cold to atleast 250 kPa (36 psi).
Caution
Using these wheel alignment
settings may cause excessive tire
wear. Only use these wheel
alignment settings for racing or
competitive driving. Excessive tire
wear is not covered under the
vehicle warranty.

Driving on Wet Roads
Rain and wet roads can reducevehicle traction and affect yourability to stop and accelerate.Always drive slower in these typesof driving conditions and avoiddriving through large puddles anddeep-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.
Flowing or rushing water creates
strong forces. Driving through
flowing water could cause the
vehicle to be carried away. If this

.Pay attention to special roadsigns (e.g., falling rocks area,winding roads, long grades,passing or no-passing zones)and take appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires andthe road creates less traction orgrip, so drive carefully. Wet ice canoccur at about 0 °C (32 °F) whenfreezing rain begins to fall. Avoiddriving on wet ice or in freezing rainuntil roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Acceleratingtoo quickly causes the wheels tospin and makes the surfaceunder the tires slick.
.Turn on Traction Control. SeeTr a c t i o n C o n t r o l / E l e c t r o n i cStability Control0245.
.The Antilock Brake System(ABS) improves vehicle stabilityduring hard stops, but thebrakes should be applied sooner
than when on dry pavement.SeeAntilock Brake System(ABS)0241.
.Allow greater following distanceand watch for slippery spots. Icypatches can occur on otherwiseclear roads in shaded areas.The surface of a curve or anoverpass can remain icy whenthe surrounding roads are clear.Avoid sudden steeringmaneuvers and braking whileon ice.
.Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place andsignal for help. Stay with the vehicleunless there is help nearby.If possible, use RoadsideAssistance. SeeRoadsideAssistance Program0368.Togethelp and keep everyone in thevehicle safe:
.Turn on the hazard warningflashers.
.Tie a red cloth to an outsidemirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
.Clear snow from the base ofthe vehicle, especially anyblocking the exhaust pipe.
.Open a window about 5 cm(2 in) on the vehicle sidethat is away from the wind,to bring in fresh air.
.Fully open the air outlets onor under the instrumentpanel.
.Adjust the climate controlsystem to circulate the airinside the vehicle and set

To s a v e f u e l , r u n t h e e n g i n e f o rshort periods to warm the vehicleand then shut the engine off andpartially close the window. Movingabout to keep warm also helps.
If it takes time for help to arrive,when running the engine, push theaccelerator pedal slightly so theengine runs faster than the idlespeed. This keeps the batterycharged to restart the vehicle and tosignal for help with the headlamps.Do this as little as possible, tosave fuel.
If the Vehicle Is Stuck
Slowly and cautiously spin thewheels to free the vehicle whenstuck in sand, mud, ice, or snow.
If stuck too severely for the tractionsystem to free the vehicle, turn thetraction system off and use therocking method. SeeTr a c t i o nControl/Electronic Stability Control0245.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).
Rocking the Vehicle to Get
it Out
Turn the steering wheel left andright to clear the area around thefront wheels. Turn off any tractionsystem. Shift back and forthbetween R (Reverse) and a lowforward gear, spinning the wheelsas little as possible. To preventtransmission wear, wait until thewheels stop spinning before shiftinggears. Release the acceleratorpedal while shifting, and presslightly on the accelerator pedalwhen the transmission is in gear.Slowly spinning the wheels in theforward and reverse directionscauses a rocking motion that couldfree the vehicle. If that does not getthe vehicle out after a few tries, itmight need to be towed out. If thevehicle does need to be towed out,seeTo w i n g t h e V e h i c l e0337.

Ride Control Systems
Traction Control/
Electronic Stability
Control
System Operation
The vehicle has a Traction ControlSystem (TCS) and StabiliTrak®,anelectronic stability control system.These systems help limit wheel slipand assist the driver in maintainingcontrol, especially on slippery roadconditions.
TCS activates if it senses that anyof the drive wheels are spinning orbeginning to lose traction. When thishappens, TCS applies the brakes tothe spinning wheels and reducesengine power to limit wheel spin.
StabiliTrak activates when thevehicle senses a difference betweenthe intended path and the directionthe vehicle is actually traveling.StabiliTrak selectively appliesbraking pressure to any one of the
vehicle wheel brakes to assist thedriver in keeping the vehicle on theintended path.
If cruise control is being used andtraction control or StabiliTrak beginsto limit wheel spin, cruise control willdisengage. Cruise control may beturned back on when roadconditions allow.
Both systems come onautomatically when the vehicle isstarted and begins to move. Thesystems may be heard or felt whilethey are operating or whileperforming diagnostic checks. Thisis normal and does not mean thereis a problem with the vehicle.
It is recommended to leave bothsystems on for normal drivingconditions, but it may be necessaryto turn TCS off if the vehicle getsstuck in sand, mud, ice, or snow.SeeIf the Vehicle Is Stuck0225and“Turning the Systems Off andOn”later in this section.
The indicator light for both systemsis in the instrument cluster. Thislight will:
.Flash when TCS is limitingwheel spin.
.Flash when StabiliTrak isactivated.
.Turn on and stay on when eithersystem is not working.
If either system fails to turn on or toactivate, a message displays in theDriver Information Center (DIC),
anddcomes on and stays on to
indicate that the system is inactiveand is not assisting the driver inmaintaining control. The vehicle issafe to drive, but driving should beadjusted accordingly.
Ifdcomes on and stays on:
1. Stop the vehicle.

Track Driver Mode
Track Driver Mode and LaunchControl are systems designed toallow increased performance whileaccelerating and/or cornering. Thisis accomplished by regulating andoptimizing the engine, brakes, andsuspension performance. Thesemodes are for use at a closedcourse race track and are notintended for use on public roads.These systems will not compensatefor driver inexperience or lack offamiliarity with the race track.
{Warning
Track Driver Mode and Launch
Control change the way
StabiliTrak and TCS perform and
should not be used on public
roads. These modes should only
be used on closed courses by
experienced drivers.
Caution
Attempting to shift when the drive
wheels are spinning and do not
have traction may cause damage
to the transmission. Damage
caused by misuse of the vehicle
is not covered by the vehicle
warranty. Do not attempt to shift
when the drive wheels do not
have traction.
Racing will result in the prematurewear of brakes, tires, and drivelinecomponents. Inspect and replacecomponents as necessary.

After the vehicle is launched, thesystem continues in TrackDriver Mode.
Limited-Slip Rear Axle
Vehicles with a limited-slip rear axlecan give more traction on snow,mud, ice, sand, or gravel. Whentraction is low, this feature allowsthe drive wheel with the mosttraction to move the vehicle. Thelimited-slip rear axle also gives thedriver enhanced control whencornering hard or completing amaneuver, such as a lane change.For vehicles with a limited-slip rearaxle, driven under severeconditions, the rear axle fluid shouldbe changed. SeeTr a c k D r i v e r M o d e0249andMaintenance Schedule0349.
Cruise Control
With cruise control, the vehicle canmaintain a speed of about 40 km/h(25 mph) or more without keepingyour foot on the accelerator. Cruisecontrol does not work at speedsbelow 40 km/h (25 mph).
{Warning
Cruise control can be dangerous
where you cannot drive safely at
asteadyspeed.Donotuse
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 excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
If the vehicle has the StabiliTrak®
system and begins to limit wheelspin while using cruise control, thecruise control will automaticallydisengage. SeeTr a c t i o n C o n t r o l /Electronic Stability Control0245.
When road conditions allow you tosafely use it again, the cruisecontrol can be turned back on.
If the brakes are applied, cruisecontrol disengages.

Vehicle Care 317
The rubber in tires ages over time.This also applies to the spare tire,if the vehicle has one, even if it isnever used. Multiple factorsincluding temperatures, loadingconditions, and inflation pressuremaintenance affect how fast agingtakes place. GM recommends thattires, including the spare ifequipped, be replaced after sixyears, regardless of tread wear. Thetire manufacture date is the last fourdigits of the DOT Tire IdentificationNumber (TIN) which is molded intoone side of the tire sidewall. Thefirst two digits represent the week(01–52) and the last two digits, theyear. For example, the third week ofthe year 2010 would have afour-digit DOT date of 0310.
Vehicle Storage
Tires age when stored normallymounted on a parked vehicle. Parkavehiclethatwillbestoredforatleast a month in a cool, dry, cleanarea away from direct sunlight toslow aging. This area should be free
of grease, gasoline, or othersubstances that can deterioraterubber.
Parking for an extended period cancause flat spots on the tires thatmay result in vibrations whiledriving. When storing a vehicle forat least a month, remove the tires orraise the vehicle to reduce theweight from the tires.
Buying New Tires
GM has developed and matched
specific tires for the vehicle. The
original equipment tires installed
were designed to meet General
Motors Tire Performance Criteria
Specification (TPC Spec)
system rating. When
replacement tires are needed,
GM strongly recommends
buying tires with the same TPC
Spec rating.
GM's exclusive TPC Spec
system considers over a dozen
critical specifications that impact
the overall performance of the
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 MS for mud
and snow. SeeTire Sidewall
Labeling0305,foradditional
information.
GM recommends replacing worn
tires in complete sets of four.
Uniform tread depth on all tires
will help to maintain the
performance of the vehicle.
Braking and handling
performance may be adversely
affected if all the tires are not
replaced at the same time.
If proper rotation and
maintenance have been done,
all four tires should wear out at
about the same time. SeeTire
Rotation0315for information

on proper tire rotation. However,
if it is necessary to replace only
one axle set of worn tires, place
the new tires on the rear axle.
Winter tires with the same speed
rating as the original equipment
tires may not be available for H,
V, W, a n d Z R s p e e d r a t e d t i r e s .
Never exceed the winter tire's
maximum speed capability when
using winter tires with a lower
speed rating.
{Warning
Tires could explode during
improper service. Attempting
to mount or dismount a tire
could cause injury or death.
Only your dealer or authorized
tire service center should
mount or dismount the tires.
{Warning
Mixing tires of different sizes
(other than those originally
installed on the vehicle), brands,
or types may cause loss of
control of the vehicle, resulting in
acrashorothervehicledamage.
Use the correct size, brand, and
type of tire on all four wheels.
{Warning
Using bias-ply tires on the
vehicle may cause the wheel
rim flanges to develop cracks
after many miles of driving.
Atireand/orwheelcouldfail
suddenly and cause a crash.
Use only radial-ply tires with
the wheels on the vehicle.
If the vehicle tires must be
replaced with a tire that does not
have a TPC Spec number, make
sure they are the same size,
load range, speed rating, and
construction (radial) as the
original tires.
Vehicles that have a tire
pressure monitoring system
could give an inaccurate
low-pressure warning if non-TPC
Spec rated tires are installed.
SeeTire Pressure Monitor
Operation0312.
The Tire and Loading
Information label indicates the
original equipment tires on the
vehicle. SeeVehicle Load Limits
0226.
Different Size Tires and
Wheels
If wheels or tires are installed thatare a different size than the originalequipment wheels and tires, vehicleperformance, including its braking,ride and handling characteristics,stability, and resistance to rollovermay be affected. If the vehicle haselectronic systems such as antilockbrakes, rollover airbags, traction
