Equipment0345.
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 power steering
system and there may be loss of
power steering assist.
Place the transmission in theproper gear.
Automatic Transmission
Move the shift lever to P (Park) orN(Neutral). To restart the enginewhen the vehicle is already moving,use N (Neutral) only.
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.
Manual Transmission
The shift lever should be in Neutraland the parking brake engaged.Hold the clutch pedal down to thefloor and start the engine.
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 the engine gets warm.Do not race the engineimmediately after starting it.
Operate the engine andtransmission gently to allow theoil to warm up and lubricate allmoving parts.
When the low fuel warning lightis on and the FUEL LEVELLOW message is displayed inthe Driver Information Center(DIC), hold the ignition switchin the START position tocontinue engine cranking.
Caution
Cranking the engine for long
periods of time, by returning the
ignition to the START position
immediately after cranking has
ended, can overheat and damage
the cranking motor, and drain the
battery. Wait at least 15 seconds
between each try, to let the
cranking motor cool down.
2. If the engine does not startafter five to 10 seconds,especially in very cold weather(below✓18 °C or 0 °F), it couldbe flooded with too much

.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)0138.Ifthis
occurs, 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.
Fuels in Foreign
Countries
The U.S., Canada, and Mexico postfuel octane ratings in anti-knockindex (AKI). For fuel not to use in aforeign country, see“ProhibitedFuels”inFuel0311.
Fuel Additives
To k e e p f u e l s y s t e m s c l e a n , T O PTIER Detergent Gasoline isrecommended. SeeFuel0311.
If TOP TIER Detergent Gasoline isnot available, one bottle of GM FuelSystem Treatment Cleaner added tothe fuel tank at every engine oilchange, can help. GM Fuel SystemTreatment Cleaner is the onlygasoline additive recommended byGeneral Motors. It is available atyour dealer.
If your vehicle is able to use E85 orFlexFuel, GM Fuel SystemTreatment Cleaner - FlexFuel is theonly recommended additive for use.Do not use any other additives withan E85 or FlexFuel vehicle. SeeE85 or FlexFuel0312.
E85 or FlexFuel
Vehicles with a yellow sticker on thefuel door can use either unleadedgasoline or fuel containing up to85% ethanol (E85). All othervehicles should use only theunleaded gasoline as described inFuel0311.
The use of E85 or FlexFuel isencouraged when the vehicle isdesigned to use it. E85 or FlexFuelis made from renewable sources.
To h e l p l o c a t e f u e l s t a t i o n s t h a tcarry E85 or FlexFuel, the U.S.Department of Energy has analternative fuels website. Seewww.afdc.energy.gov/afdc/locator/stations.

Passing
More passing distance is neededwhen towing a trailer. Thecombination will not accelerate asquickly and is longer so it isnecessary to go much fartherbeyond the passed vehicle beforereturning to the lane.
Backing Up
Hold the bottom of the steeringwheel with one hand. To move thetrailer to the left, move that hand tothe left. To move the trailer to theright, move your hand to the right.Always back up slowly and,if possible, have someoneguide you.
Making Turns
Caution
Making very sharp turns while
trailering could cause the trailer to
come in contact with the vehicle.
The vehicle could be damaged.
Avoid making very sharp turns
while trailering.
When turning with a trailer, makewider turns than normal. Do this sothe trailer will not strike softshoulders, curbs, road signs, trees,or other objects. Avoid jerky orsudden maneuvers. Signal well inadvance.
If the trailer turn signal bulbs burnout, the arrows on the instrumentcluster will still flash for turns. It isimportant to check occasionally tobe sure the trailer bulbs are stillworking.
Driving on Grades
Reduce speed and shift to a lowergearbeforestarting down a long orsteep downgrade. If thetransmission is not shifted down, thebrakes might get hot and no longerwork well.
Vehicles can tow in D (Drive). Shiftthe transmission to a lower gear ifthe transmission shifts too oftenunder heavy loads and/or hillyconditions.
The Tow/Haul Mode may be used ifthe transmission shifts too often.SeeTo w / H a u l M o d e0282.
When towing at high altitude onsteep uphill grades, consider thefollowing: Engine coolant will boil atalowertemperaturethanatnormalaltitudes. If the engine is turned offimmediately after towing at highaltitude on steep uphill grades, thevehicle may show signs similar toengine overheating. To avoid this,let the engine run while parked,preferably on level ground, with thetransmission in P (Park) for a fewminutes before turning the engineoff. If the overheat warning comeson, seeEngine Overheating0372.
Parking on Hills
{Warning
Parking the vehicle on a hill with
the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
People can be injured, and both
the vehicle and the trailer can be
damaged. When possible, always
park the rig on a flat surface.
