Starting the Engine
If the vehicle has a diesel engine,see the Duramax dieselsupplement.
To p l a c e t h e t r a n s m i s s i o n i n t h eproper gear:
Move the shift lever to P (Park) orN(Neutral). The engine will not startin any other position. To restart theengine when the vehicle is alreadymoving, use N (Neutral) only.
Caution
If you add electrical parts or
accessories, you could change
the way the engine operates. Any
resulting damage would not be
covered by the vehicle warranty.
SeeAdd-On Electrical
Equipment0212.
Caution
Do not try to shift to P (Park) if the
vehicle is moving. If you do, you
could damage the transmission.
Shift to P (Park) only when the
vehicle is stopped.
Caution
If the steering wheel is turned
until it reaches the end of its
travel, and is held in that position
while starting the vehicle, damage
may occur to the hydraulic power
steering system and there may be
loss of power steering assist.
Starting Procedure
1. With your foot off theaccelerator pedal, turn theignition key to START. Whenthe engine starts, let go of thekey. The idle speed will godown as your engine getswarm. Do not race the engineimmediately after starting it.

2. Press the +/✓buttons on theshift lever, to select the desiredrange of gears for currentdriving conditions.
When M (Manual Mode) is selectedanumberdisplaysintheDICnexttothe M indicating the current gear.
This number is the highest gear thatcan be used. However, the vehiclecan automatically shift to lowergears as it adjusts to drivingconditions. This means that allgears below that number areavailable. When 5 (Fifth) is selected,1(First) through 5(Fifth) gears areautomatically shifted by the vehicle,but 6 (Sixth) cannot be used untilthe +/✓button on the steeringcolumn lever is used to change tothe gear.
Grade Braking is not available whenRange Selection Mode is active.SeeTo w / H a u l M o d e0187.
While using Range Selection Mode,cruise control and the Tow/HaulMode can be used.
Caution
Spinning the tires or holding the
vehicle in one place on a hill
using only the accelerator pedal
may damage the transmission.
The repair will not be covered by
the vehicle warranty. If you are
stuck, do not spin the tires. When
stopping on a hill, use the brakes
to hold the vehicle in place.
Low Traction Mode
Low Traction Mode can assist invehicle acceleration when roadconditions are slippery. While thevehicle is at a stop, select thesecond gear range using RangeSelection Mode. This will limittorque to the wheels after it detectswheel slip, preventing the tires fromspinning.
Tow/Haul Mode
If equipped, Tow/Haul Mode adjuststhe transmission shift pattern toreduce shift cycling, providingincreased performance, vehiclecontrol, and transmission coolingwhen towing or hauling heavy loads.
Turn the Tow/Haul Mode on and offby pressing the button on theinstrument panel. When Tow/Haul ison, a light on the instrument clusterwill come on.

Brakes
Antilock Brake
System (ABS)
This vehicle has an Antilock BrakeSystem (ABS), an advancedelectronic braking system that helpsprevent a braking skid.
When the vehicle begins to driveaway, ABS checks itself.Amomentarymotororclickingnoisemay be heard while this test is goingon, and it may even be noticed thatthe brake pedal moves a little. Thisis normal.
If there is a problem with ABS, thiswarning light stays on. SeeAntilockBrake System (ABS) WarningLight0104.
If driving safely on a wet road and itbecomes necessary to slam on thebrakes and continue braking toavoid a sudden obstacle, acomputer senses the wheels areslowing down. If one of the wheelsis about to stop rolling, the computerwill separately work the brakes ateach wheel.
ABS can change the brake pressureto each wheel, as required, fasterthan any driver could. This can helpyou steer around the obstacle whilebraking hard.
As the brakes are applied, thecomputer keeps receiving updateson wheel speed and controlsbraking pressure accordingly.
Remember: ABS does not changethe time needed to get a foot up tothe brake pedal or always decreasestopping distance. If you get tooclose to the vehicle in front of you,there will not be enough time toapply the brakes if that vehiclesuddenly slows or stops. Alwaysleave enough room up ahead tostop, even with ABS.

Cruise Control
{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 equipped with cruise control, aspeed of about 40 km/h (25 mph) ormore can be maintained withoutkeeping your foot on theaccelerator. Cruise control does notwork at speeds below about 40 km/h(25 mph).
If the vehicle has StabiliTrak and thesystem begins to limit wheel spin,cruise control will automaticallydisengage. SeeTr a c t i o n C o n t r o l /Electronic Stability Control0190.
When road conditions allow cruisecontrol to be safely used again,cruise control can be turnedback on.
If the brakes are applied, cruisecontrol disengages.
I:Press to turn cruise control onor off. The white indicator comes onin the instrument cluster whencruise control is turned on.
+RES :If there is a set speed inmemory, press briefly to resume to apreviously set speed, or press and
hold to accelerate. If cruise controlis already active, use to increasevehicle speed.
SET✓:Press briefly to set thespeed and activate cruise control,or press and hold to decelerate.If cruise control is already active,use to decrease vehicle speed.
[:Press to disengage cruisecontrol without erasing the setspeed from memory.
Setting Cruise Control
IfIis on when not in use, the
SET✓or +RES button could getpressed and go into cruise when not
desired. KeepIoff when cruise is
not being used.
1. PressIto turn the cruise
system on.
2. Get up to the desired speed.
3. Press and release SET✓.Thedesired set speed brieflyappears in the instrumentcluster.

234 Vehicle Care
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 andSpecifications0309.
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 wrongreplacement brake parts areinstalled or if parts are improperlyinstalled.
Brake Fluid
The brake master cylinder reservoiris filled with DOT 3 brake fluid. SeeEngine Compartment Overview0218for the location of thereservoir.
There are only two reasons why thebrake fluid level in the reservoir maygo down:
.Normal brake lining wear. Whennew linings are installed, thefluid level goes back up.
.Afluidleakinthebrakehydraulic system. Have thebrake hydraulic system fixed.With a leak, the brakes will notwork well.
Always clean the brake fluidreservoir cap and the area aroundthe cap before removing it.
Do not top off the brake fluid.Adding fluid does not correct a leak.If fluid is added when the linings areworn, there will be too much fluidwhen new brake linings areinstalled. Add or remove fluid, asnecessary, only when work is doneon the brake hydraulic system.
{Warning
If too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the vehicle could be damaged.

All-Season Tires
This vehicle may come withall-season tires. These tires aredesigned to provide good overallperformance on most road surfacesand weather conditions. Originalequipment tires designed to GM'sspecific tire performance criteriahave a TPC specification codemolded onto the sidewall. Originalequipment all-season tires can beidentified by the last two charactersof this TPC code, which willbe“MS.”
Consider installing winter tires onthe vehicle if frequent driving onsnow or ice-covered roads isexpected. All-season tires provideadequate performance for mostwinter driving conditions, but theymay not offer the same level oftraction or performance as wintertires on snow or ice-covered roads.SeeWinter Tires0253.
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 Tires0268.
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.
All-Terrain Tires
This vehicle may have All-TerrainTires. These tires provide goodperformance on most road surfaces,weather conditions, and for off-roaddriving.
The tread pattern on these tires maywear more quickly than other tires.Consider rotating the tires morefrequently than at 12 000 km(7,500 mi) intervals if irregular wearis noted when the tires areinspected. SeeTireInspection0265.

266 Vehicle Care
Use this rotation pattern when
rotating the tires.
If the vehicle has a compact
spare tire, do not include it in the
tire rotation.
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 Pressure0260andVehicle
Load Limits0171.
Reset the Tire Pressure Monitor
System. SeeTire Pressure
Monitor Operation0262.
Check that all wheel nuts are
properly tightened. See“Wheel
Nut Torque”underCapacities
and Specifications0309.
{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.
Dual Tire Rotation
When the vehicle is new,or whenever a wheel, wheel bolt,or wheel nut is replaced, check thewheel nut torque after160, 1 600, and 10 000 km (100,1,000, and 6,000 mi) of driving. Forproper wheel nut tighteninginformation, see“Removing the FlatTire and Installing the Spare Tire”underTire Changing0274.Alsosee“Wheel Nut Torque”underCapacities and Specifications0309.
The outer tire on a dual wheel setupgenerally wears faster than theinner tire. Tires last longer and wearmore evenly if they are rotated. SeeTire Inspection0265andTireRotation0265.AlsoseeMaintenance Schedule0297.
{Warning
If the vehicle is operated with a
tire that is underinflated, the tire
can overheat. An overheated tire
can lose air suddenly or catch
