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 muchgasoline. Try pushing theaccelerator pedal all the way tothe floor and holding it therewhile holding the key in STARTfor up to 15 seconds. Wait atleast 15 seconds between eachtry, to allow the cranking motorto cool down. When the enginestarts, let go of the key andaccelerator. If the vehicle startsbriefly but then stops again, dothe same thing. This clears theextra gasoline from the engine.Do not race the engineimmediately after starting it.Operate the engine and
transmission gently until the oilwarms up and lubricates allmoving parts.
Engine Heater
If the vehicle has a diesel engine,see the Duramax dieselsupplement.
{Warning
Do not plug in the engine block
heater while the vehicle is in
parked in a garage or under a
carport. Property damage or
personal injury may result. Always
park the vehicle in a clear open
area away from buildings or
structures.
If equipped, the engine heater canprovide easier starting and betterfuel economy during enginewarm-up in cold weather conditionsat or below✓18 °C (0 °F). Vehicleswith an engine heater should beplugged in at least four hours beforestarting. An internal thermostat inthe plug-end of the cord may exist,

Torque Lock
If you are parking on a hill and youdo not shift the transmission intoP(Park) properly, the weight of thevehicle may put too much force onthe parking pawl in thetransmission. You may find it difficultto pull the shift lever out of P (Park).This is called torque lock. Toprevent torque lock, set the parkingbrake and then shift into P (Park)properly before you leave the driverseat. To find out how, seeShiftingInto Park0238.
When you are ready to drive, movethe shift lever out of P (Park) beforeyou release the parking brake.
If torque lock does occur, you mayneed to have another vehicle pushyours a little uphill to take some ofthe pressure from the parking pawlin the transmission. You will then beable to pull the shift lever out ofP(Park).
Shifting out of Park
This vehicle is equipped with anelectronic shift lock release system.The shift lock release isdesigned to:
.Prevent ignition key removalunless the shift lever is inP(Park).
.Prevent movement of the shiftlever out of P (Park), unless theignition is in ON/RUN and theregular brake pedal is applied.
To s h i f t o u t o f P ( P a r k ) :
1. Apply the brake pedal.
2. Press the button on the shiftlever.
3. Move the shift lever to thedesired position.
If you still are unable to shift out ofP(Park):
1. Ease the pressure on the shiftlever.
2. While holding down the brakepedal and pressing the shiftlever button, move the shiftlever all the way into P (Park).
3. While holding the shift leverbutton, move the shift lever tothe desired position.
If you are still having a problemshifting, then have the vehicleserviced soon.
This vehicle may have the SafetyBelt Assurance System, which mayprevent the vehicle from shifting outof P (Park). SeeSafety BeltMessages0136.
Parking
If the vehicle has a manualtransmission, before you get out ofthe vehicle, move the shift lever intoR(Reverse), and firmly apply theparking brake. Once the shift leverhas been placed into R (Reverse)with the clutch pedal pressed in,turn the ignition key to LOCK/OFF,remove the key and release theclutch.
If you are parking on a hill, or if thevehicle is pulling a trailer, seeDriving Characteristics and TowingTips0270.

Running the Vehicle
While Parked
It is better not to park with theengine running.
If the vehicle is left with the enginerunning, follow the proper steps tobe sure the vehicle will not move.SeeShifting Into Park0238andEngine Exhaust0240.Ifthevehiclehas a manual transmission, seeParking0239.
If parking on a hill and pulling atrailer, seeDriving Characteristicsand Towing Tips0270.
Automatic
Transmission
If equipped, there is an electronicshift lever position indicator withinthe instrument cluster. This displaycomes on when the ignition key isturned to the ON/RUN position.
P:This position locks the rearwheels. It is the best position to usewhen starting the engine becausethe vehicle cannot move easily.When parked on a hill, especiallywhen the vehicle has a heavy load,you might notice an increase in the
effort to shift out of P (Park). See“To r q u e L o c k”underShifting IntoPark0238.
{Warning
It is dangerous to get out of the
vehicle if the shift lever is not fully
in P (Park) with the parking brake
firmly set. The vehicle can roll.
Do not leave the vehicle when the
engine is running. If you have left
the engine running, the vehicle
can move suddenly. You or others
could be injured. To be sure the
vehicle will not move, even when
you are on fairly level ground,
always set the parking brake and
move the shift lever to P (Park).

{Warning
If you have four-wheel drive, the
vehicle will be free to roll—even
if the shift lever is in P (Park)—if
the transfer case is in N (Neutral).
So, be sure the transfer case is in
adrivegear,Two-WheelDrive
High or Four-Wheel Drive High or
Four-Wheel Drive Low—not in
N(Neutral). SeeShifting Into
Park0238.
R:Use this gear to back up.
Caution
Shifting to R (Reverse) while the
vehicle is moving forward could
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Shift to
R(Reverse) only after the vehicle
is stopped.
To r o c k t h e v e h i c l e b a c k a n d f o r t h t oget out of snow, ice, or sand withoutdamaging the transmission, seeIfthe Vehicle Is Stuck0225.
N:In this position, the engine doesnot connect with the wheels. Torestart when you are alreadymoving, use N (Neutral) only. Also,use N (Neutral) when the vehicle isbeing towed.
{Warning
Shifting into a drive gear while the
engine is running at high speed is
dangerous. Unless your foot is
firmly on the brake pedal, the
vehicle could move very rapidly.
Yo u c o u l d l o s e c o n t r o l a n d h i t
people or objects. Do not shift
into a drive gear while the engine
is running at high speed.
Caution
Shifting out of P (Park) or
N(Neutral) with the engine
running at high speed may
damage the transmission. The
repairs would not be covered by
the vehicle warranty. Be sure the
engine is not running at high
speed when shifting the vehicle.
D:This position is for normaldriving. It provides the best fueleconomy. If you need more powerfor passing, and you are:
.Going less than about 55 km/h(35 mph), push the acceleratorpedal about halfway down.
.Going about 55 km/h (35 mph) ormore, push the accelerator allthe way down.
By doing this, the vehicle shiftsdown to the next gear and hasmore power.
D(Drive) can be used when towingatrailer,carryingaheavyload,driving on steep hills, or driving

off-road. Shift the transmission to alower gear range selection if thetransmission shifts too often. SeeManual Mode0244.
Downshifting the transmission inslippery road conditions could resultin skidding. See“Skidding”underLoss of Control0217.
The vehicle has a shift stabilizationfeature that adjusts the transmissionshifting to the current drivingconditions in order to reduce rapidupshifts and downshifts. This shiftstabilization feature is designed todetermine, before making anupshift, if the engine is able tomaintain vehicle speed by analyzingthings such as vehicle speed,throttle position, and vehicle load.If the shift stabilization featuredetermines that a current vehiclespeed cannot be maintained, thetransmission does not upshift andinstead holds the current gear.In some cases, this could appear tobe a delayed shift, however thetransmission is operating normally.
The transmission uses adaptiveshift controls. The adaptive shiftcontrol process continuallycompares key shift parameters topre-programmed ideal shifts storedin the transmission’scomputer.Thetransmission constantly makesadjustments to improve vehicleperformance according to how thevehicle is being used, such as withaheavyloadorwhenthetemperature changes. During thisadaptive shift control process,shifting might feel different as thetransmission determines the bestsettings.
When temperatures are very cold,the transmission's gear shiftingcould be delayed providing morestable shifts until the engine warmsup. Shifts could be more noticeablewith a cold transmission. Thisdifference in shifting is normal.
M:This position allows selection ofarangeofgearsappropriateforcurrent driving conditions. SeeManual Mode0244.
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.
Normal Mode Grade Braking
Normal Mode Grade Braking isenabled when the vehicle is started,but is not enabled in RangeSelection Mode. It assists inmaintaining desired vehicle speedswhen driving on downhill grades byusing the engine and transmissionto slow the vehicle.

244 Driving and Operating
Manual Mode
Range Selection Mode
Range Selection Mode helps controlthe vehicle's transmission andvehicle speed while driving downhillor towing a trailer by letting youselect a desired range of gears.
To u s e t h i s f e a t u r e :
1. Move the shift lever toM(ManualMode).
2. Press the plus/minus button onthe shift lever to select thedesired range of gears forcurrent driving conditions.
When the shift lever is moved fromD(Drive) to M(Manual Mode), anumber displays next to the M,indicating the current transmissionrange.
This number is the highest gear thatthe transmission will command whileoperating in M (Manual Mode). Allgears below that number areavailable. As driving conditionschange, the transmission canautomatically shift to lower gears.For example, when 5 (Fifth) isselected, 1 (First) through 5 (Fifth)gears are automatically shifted bythe transmission, but 6 (Sixth)cannot be used until the plus/minusbutton on the shift lever is used tochange to the range.
When the shift lever is moved fromD(Drive)toM(ManualMode),adownshift may occur. The gear thatthe transmission is operating inwhen the shift lever is moved fromD(Drive) to M(Manual Mode)determines if a downshift occurs.See the following chart.

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 assists invehicle acceleration when roadconditions are slippery, such as withice or snow. While the vehicle is at astop, select M2 using RangeSelection Mode. This will limittorque to the wheels and help toprevent the tires from spinning.
Tow/Haul Mode
If equipped, Tow/Haul Mode adjuststhe transmission shift pattern toreduce shift cycling. This providesincreased performance, vehiclecontrol, and transmission coolingwhen driving down steep hills ormountain grades, towing, or haulingheavy loads.
Turn the Tow/Haul Mode on and offby pressing the button on the centerstack. When the Tow/Haul Mode isenabled, a light on the instrumentcluster will come on.
