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.

Launch Control (ManualTransmissions Only)
This feature is available in TrackDriver Mode, and allows the vehicleto reach high levels of accelerationin a straight line. Launch Controladjusts tire slip during standing startlaunches. Use this feature duringclosed course race events whereconsistent zero to sixty and quartermile times are desirable.
Launch Control is onlyavailable when:
.Track Driver Mode is selected.
.The vehicle is not moving.
.The steering wheel is pointingstraight.
.The clutch pedal is pressed andthe vehicle is in 1 (First) gear.
.The accelerator pedal is rapidlyapplied to wide open throttle.
This feature initially limits enginespeed as the accelerator pedal israpidly pressed to wide openthrottle. A smooth, quick release ofthe clutch pedal, while maintainingthe fully pressed accelerator pedal,will manage wheel slip. SeeManualTr a n s m i s s i o n0240.

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.

damaged. It may also not detect a
vehicle on winding or hilly roads,
or in conditions that can limit
visibility such as fog, rain,
or snow, or if the headlamps or
windshield are not cleaned or in
proper condition. Keep the
windshield, headlamps, and FCA
sensors clean and in good repair.
Collision Alert
When your vehicle approachesanother detected vehicle too rapidly,the red FCA display will flash on thewindshield. Also, eight rapidhigh-pitched beeps will sound fromthe front. When this Collision Alertoccurs, the brake system mayprepare for driver braking to occur
more rapidly which can cause abrief, mild deceleration. Continue toapply the brake pedal as needed.Cruise control may be disengagedwhen the Collision Alert occurs.
Tailgating Alert
The vehicle ahead indicator willdisplay amber when you arefollowing a detected vehicle aheadmuch too closely.
Selecting the Alert Timing
The Collision Alert control is on the
steering wheel. Press[to set the
FCA timing to Far, Medium, Near,or Off. The first button press showsthe current setting on the Head-UpDisplay (HUD). Additional buttonpresses will change this setting. Thechosen setting will remain until it ischanged and will affect the timing ofboth the Collision Alert and theTa i l g a t i n g A l e r t f e a t u r e s .

Brakes
Disc brake pads have built-in wearindicators that make a high-pitchedwarning sound when the brake padsare worn and new pads are needed.The sound can come and go or canbe heard all the time when thevehicle is moving, except whenapplying the brake pedal firmly.
{Warning
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
acrash.Whenthebrakewear
warning sound is heard, have the
vehicle serviced.
Caution
Continuing to drive with worn-out
brake pads could result in costly
brake repair.
Some driving conditions or climatescan cause a brake squeal when thebrakes are first applied or lightlyapplied. This does not meansomething is wrong with the brakes.
Properly torqued wheel nuts arenecessary to help prevent brakepulsation. When tires are rotated,inspect brake pads for wear andevenly tighten wheel nuts in theproper sequence to torquespecifications. SeeCapacities andSpecifications0362.
Brake pads should be replaced ascomplete sets.
Brake Pedal Travel
See your dealer if the brake pedaldoes not return to normal height,or if there is a rapid increase inpedal travel. This could be a signthat brake service may be required.
Replacing Brake System Parts
Always replace brake system partswith new, approved replacementparts. If this is not done, the brakesmay not work properly. The brakingperformance expected can changein many other ways if the wrong
replacement brake parts areinstalled or if parts are improperlyinstalled.
Brake Fluid
The brake/clutch master cylinderreservoir is filled with GM approvedDOT 4 brake fluid as indicated onthe reservoir cap. SeeEngineCompartment Overview0274forthe location of the reservoir.
Checking Brake Fluid
Place the vehicle in P (Park) orNeutral with the parking brakeapplied if equipped with a manualtransmission. On a level surface,the brake fluid level should bebetween the minimum andmaximum marks on the brake fluidreservoir.

304 Vehicle Care
Winter Tires
This vehicle was not originallyequipped with winter tires. Wintertires are designed for increasedtraction on snow and ice-coveredroads. Consider installing wintertires on the vehicle if frequentdriving on ice or snow coveredroads is expected. See your dealerfor details regarding winter tireavailability and proper tire selection.Also, seeBuying New Tires0317.
With winter tires, there may bedecreased dry road traction,increased road noise, and shortertread life. After changing to wintertires, be alert for changes in vehiclehandling and braking.
If using winter tires:
.Use tires of the same brand andtread type on all four wheelpositions.
.Use only radial ply tires of thesame size, load range, andspeed rating as the originalequipment tires.
Winter tires with the same speedrating as the original equipment tiresmay not be available for H, V, W, Y,and ZR speed rated tires. If wintertires with a lower speed rating arechosen, never exceed the tire'smaximum speed capability.
Low-Profile Tires
Caution
Low-profile tires are more
susceptible to damage from road
hazards or curb impact than
standard profile tires. Tire and/or
wheel assembly damage can
occur when coming into contact
with road hazards like potholes,
or sharp edged objects, or when
sliding into a curb. The warranty
does not cover this type of
damage. Keep tires set to the
correct inflation pressure and
when possible, avoid contact with
curbs, potholes, and other road
hazards.
Summer Tires
Ultra High Performance SummerTires
This vehicle may come with 245/40R19 and 275/35R19 ultra highperformance summer tires. Thesetires have a special tread andcompound that are optimized formaximum dry and wet roadperformance. This special tread andcompound will have decreasedperformance in cold climates, andon ice and snow. Driving a vehiclewith ultra high performance summertires when temperatures are belowapproximately 5 °C (40 °F) is notrecommended. If driving in theseconditions, winter tires should beinstalled. SeeWinter Tires0304.
Caution
Ultra high performance summer
tires have rubber compounds that
lose flexibility and may develop
surface cracks in the tread area
at temperatures below -7 °C (20 °

316 Vehicle Care
Use this rotation pattern if the
vehicle has different size tires
on the front and rear.
Adjust the front and rear tires to
the recommended inflation
pressure on the Tire and
Loading Information label after
the tires have been rotated. See
Tire Pressure0309andVehicle
Load Limits0226.
Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation0312.
Check that all wheel nuts are
properly tightened. See“Wheel
Nut Torque”underCapacities
and Specifications0362.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper
towel can be used; however, use
ascraperorwirebrushlaterto
remove all rust or dirt.
Lightly coat the center of the
wheel hub with wheel bearing
grease after a wheel change or
tire rotation to prevent corrosion
or rust build-up. Do not get
grease on the flat wheel
mounting surface or on the
wheel nuts or bolts.
When It Is Time for New
Tires
Factors such as maintenance,temperatures, driving speeds,vehicle loading, and road conditionsaffect the wear rate of the tires.
Treadwear indicators are one way totell when it is time for new tires.Treadwear indicators appear whenthe tires have only 1.6 mm (1/16 in)or less of tread remaining. SeeTireInspection0315andTire Rotation0315.
