FM Stereo
FM stereo gives the best sound, butFM signals reach only about 16 to65 km (10 to 40 mi). Tall buildings orhills can interfere with FM signals,causing the sound to fade inand out.
Cellular Phone Usage
Cellular phone usage may causeinterference with the radio. Thisinterference may occur whenmaking or receiving phone calls,charging the phone's battery,or simply having the phone on. Thisinterference causes an increasedlevel of static while listening to theradio. If static is received whilelistening to the radio, unplug thecellular phone and turn it off.
Multi-Band Antenna
The multi-band antenna is on theroof of the vehicle. The antenna isused for the Navigation System,OnStar®and the SiriusXM®SatelliteRadio Service System if the vehiclehas these features. Tall buildings,hills, trees, heavy foliage, tunnels,bridges, and garages will affectreception. Keep the antenna clear ofobstructions for clear reception.Make sure there is sufficientclearance when entering garages orparking structures.

.Allow greater following distanceand watch for slippery spots. Icypatches can occur on otherwiseclear roads in shaded areas.The surface of a curve or anoverpass can remain icy whenthe surrounding roads are clear.Avoid sudden steeringmaneuvers and braking whileon ice.
.Turn off cruise control.
Blizzard Conditions
Stop the vehicle in a safe place andsignal for help. Stay with the vehicleunless there is help nearby.If possible, use RoadsideAssistance. SeeRoadsideAssistance Program0316.Togethelp and keep everyone in thevehicle safe:
.Turn on the hazard warningflashers.
.Tie a red cloth to an outsidemirror.
{Warning
Snow can trap engine exhaust
under the vehicle. This may
cause exhaust gases to get
inside. Engine exhaust contains
carbon monoxide (CO), which
cannot be seen or smelled. It can
cause unconsciousness and even
death.
If the vehicle is stuck in snow:
.Clear snow from the base ofthe vehicle, especially anyblocking the exhaust pipe.
.Open a window about 5 cm(2 in) on the vehicle sidethat is away from the wind,to bring in fresh air.
.Fully open the air outlets onor under the instrumentpanel.
.Adjust the climate controlsystem to circulate the airinside the vehicle and set

1(ACC/ACCESSORY):This is theposition in which you can operatethings like the radio and thewindshield wipers when the engineis off.
2(ON/RUN):This position can beused to operate the electricalaccessories and to display someinstrument cluster warning andindicator lights. This position canalso be used for service anddiagnostics, and to verify the properoperation of the malfunctionindicator lamp as may be requiredfor emission inspection purposes.The switch stays in this positionwhen the engine is running.
If you leave the key in the ACC/ACCESSORY or ON/RUN positionwith the engine off, the battery couldbe drained. You may not be able tostart the vehicle if the battery isallowed to drain for an extendedperiod of time.
3(START):This is the position thatstarts the engine. When the enginestarts, release the key. The ignitionswitch returns to ON/RUN fordriving.
Awarningtonewillsoundwhenthedriver door is opened, the ignition isin ACC/ACCESSORY or LOCK/OFFand the key is in the ignition.
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.

178 Driving and Operating
Operate the engine andtransmission gently to allow theoil to warm up and lubricate allmoving parts.
When the Low Fuel warninglamp is on and the FUELLEVEL LOW message isdisplayed in the DriverInformation Center (DIC), theComputer-Controlled CrankingSystem is disabled to preventpossible vehicle componentdamage. When this happens,hold the ignition switch in theSTART position to continueengine 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 5-10 seconds, especiallyin very cold weather (below✓18 °C or 0 °F), it could beflooded with too muchgasoline. Try pushing theaccelerator pedal all the way tothe floor and holding it there asyou hold the key in START forup to 15 seconds. Wait at least15 seconds between each try,to allow the cranking motor tocool 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 andtransmission gently until the oilwarms up and lubricates allmoving parts.
Fast Idle System
If equipped, this feature is availableonly with cruise control. The manualfast idle switch is operated using thecruise control buttons on the leftside of the steering wheel.
This system can be used toincrease engine idle speedwhenever the following conditionsare met:
.The parking brake is set.
.The brake pedal is not pressed.
.The vehicle must not be movingand the accelerator must not bepressed.
To c o n t r o l t h e f a s t i d l e :
.To e n a b l e t h e F a s t I d l e S y s t e m ,press and release the cruisecontrol on/off button and ensurethat the switch indicator lightis lit.

Warning (Continued)
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).
SeeShifting Into Park0180.
If you are towing a trailer, see
Driving Characteristics and
To w i n g T i p s0202.
If you have to leave the vehicle withthe engine running, be sure thevehicle is in P (Park) and theparking brake is firmly set. After theshift lever is moved into P (Park),hold the regular brake pedal down.Then, see if you can move the shiftlever away from P (Park) without
first pulling it toward you. If you can,it means that the shift lever was notfully locked into P (Park).
Torque Lock
If you are parking on a hill and youdo not shift the transmission intoP(Park) properly, the weight of thevehicle can put too much force onthe parking pawl in thetransmission. It might be difficult topull 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 Park0180.
When you are ready to drive, movethe shift lever out of P (Park) beforereleasing the parking brake.
If torque lock does occur, you mightneed to have another vehicle pushyours a little uphill to take some ofthe pressure from the parking pawlin the transmission. Then youshould be able to pull the shift leverout of P (Park).
Shifting out of Park
The vehicle has an automatictransmission shift lock controlsystem. You have to fully apply thebrakes before you can shift fromP(Park) when the ignition is in ON/RUN or ACC/ACCESSORY. SeeAutomatic Transmission0183.
The shift lock control system isdesigned to:
.Prevent the ignition key frombeing removed unless the shiftlever is in P (Park).
.Prevent movement of the shiftlever out of P (Park), unless theignition is in ON/RUN or ACC/ACCESSORY and the regularbrake pedal is applied.
The shift lock control system isalways functional except in the caseof a dead battery or low voltage(less than 9 V) battery.
If the vehicle has an unchargedbattery or a battery with low voltage,try charging or jump starting thebattery. SeeJump Starting - NorthAmerica0282.
