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

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.

When the System Does Not
Seem to Work Properly
The system may not detect lanes aswell when there are:
.Close vehicles ahead.
.Sudden lighting changes, suchas when driving through tunnels.
.Banked roads.
If the LDW system is not functioningproperly when lane markings areclearly visible, cleaning thewindshield may help.
LDW alerts may occur due totar marks, shadows, cracks inthe road, temporary or constructionlane markings, or other roadimperfections. This is normal systemoperation; the vehicle does not needservice. Turn LDW off if theseconditions continue.

GM recommends the use of TOPTIER®detergent gasoline tokeep the engine cleaner andreduce engine deposits. Seewww.toptiergas.com for a list ofTOP TIER detergent gasolinemarketers and applicable countries.
Do not use any fuel labeled E85 orFlexFuel. Do not use gasoline withethanol levels greater than 15% byvolume.
Premium unleaded gasolinemeeting ASTM specification D4814with a posted octane rating of 93 ishighly recommended for best

performance and fuel economy.Unleaded gasoline with an octanerated as low as 87 can be used.Using unleaded gasoline ratedbelow 93 octane, however, will leadto reduced acceleration and fueleconomy. If knocking occurs, use agasoline rated at 93 octane as soonas possible, otherwise, the enginecould be damaged. If heavyknocking is heard when usinggasoline with a 93 octane rating, theengine needs service.
Prohibited Fuels
Caution
Do not use fuels with any of the
following conditions; doing so
may damage the vehicle and void
its warranty:
.For vehicles which are notFlexFuel, fuel labeledgreater than 15% ethanol byvolume, such as mid-levelethanol blends (16–50%ethanol), E85, or FlexFuel.
(Continued)
Caution (Continued)
.Fuel with any amount ofmethanol, methylal, andaniline. These fuels cancorrode metal fuel systemparts or damage plastic andrubber parts.
.Fuel containing metals suchas methylcyclopentadienylmanganese tricarbonyl(MMT), which can damagethe emissions controlsystem and spark plugs.
.Fuel with a posted octanerating of less than therecommended fuel. Usingthis fuel will lower fueleconomy and performance,and may decrease the life ofthe emissions catalyst.
California Fuel
Requirements
If the vehicle is certified to meetCalifornia Emissions Standards, it isdesigned to operate on fuels thatmeet California specifications. Seethe underhood emission controllabel. If this fuel is not available instates adopting California EmissionsStandards, the vehicle will operatesatisfactorily on fuels meetingfederal specifications, but emissioncontrol system performance may beaffected. The malfunction indicatorlamp could turn on and the vehiclemay not pass a smog-check test.SeeMalfunction Indicator Lamp(Check Engine Light)0100.Ifthisoccurs, return to your authorizeddealer for diagnosis. If it isdetermined that the condition iscaused by the type of fuel used,repairs may not be covered by thevehicle warranty.

Filling the Tank
{Warning
Fuel vapors and fuel fires burn
violently and can cause injury or
death.
.To h e l p a v o i d i n j u r i e s t o y o uand others, read and followall the instructions on thefuel pump island.
.Turn off the engine whenrefueling.
.Keep sparks, flames, andsmoking materials awayfrom fuel.
.Do not leave the fuel pumpunattended.
.Do not use a cell phonewhile refueling.
.Do not re-enter the vehiclewhile pumping fuel.
.Keep children away fromthe fuel pump and never letchildren pump fuel.
(Continued)
Warning (Continued)

{Warning
Overfilling the fuel tank by more
than three clicks of a standard fill
nozzle may cause:
.Vehicle performance issues,including engine stalling anddamage to the fuel system.
.Fuel spills.
.Potential fuel fires.
Be careful not to spill fuel. Wait afew seconds after you have finishedpumping before removing thenozzle. Clean fuel from paintedsurfaces as soon as possible. SeeExterior Care0338.
When replacing the fuel cap, turn itclockwise until it clicks. Make surethe cap is fully installed. Thediagnostic system can determine ifthe fuel cap has been left off or
improperly installed. This wouldallow fuel to evaporate into theatmosphere. SeeMalfunctionIndicator Lamp (Check EngineLight)0100.
{Warning
If a fire starts while you are
refueling, do not remove the
nozzle. Shut off the flow of fuel by
shutting off the pump or by
notifying the station attendant.

Caution
If a new fuel cap is needed, be
sure to get the right type of cap
from your dealer. The wrong type
of fuel cap may not fit properly,
may cause the malfunction
indicator lamp to light, and could
damage the fuel tank and
emissions system. See
Malfunction Indicator Lamp
(Check Engine Light)0100.
Filling a Portable Fuel
Container
{Warning
Filling a portable fuel container
while it is in the vehicle can cause
fuel vapors that can ignite either
