.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 Program0311.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

178 Driving and Operating
If the Vehicle Is Stuck
Slowly and cautiously spin thewheels to free the vehicle whenstuck in sand, mud, ice, or snow.
If stuck too severely for the tractionsystem to free the vehicle, turn thetraction system off and use therocking method. SeeTr a c t i o nControl/Electronic StabilityControl0197.
{Warning
If the vehicle's tires spin at high
speed, they can explode, and you
or others could be injured. The
vehicle can overheat, causing an
engine compartment fire or other
damage. Spin the wheels as little
as possible and avoid going
above 56 km/h (35 mph).
Rocking the Vehicle to Get
it Out
Turn the steering wheel left andright to clear the area around thefront wheels. Turn off any tractionsystem. Shift back and forth
between R (Reverse) and a lowforward gear, spinning the wheelsas little as possible. To preventtransmission wear, wait until thewheels stop spinning before shiftinggears. Release the acceleratorpedal while shifting, and presslightly on the accelerator pedalwhen the transmission is in gear.Slowly spinning the wheels in theforward and reverse directionscauses a rocking motion that couldfree the vehicle. If that does not getthe vehicle out after a few tries, itmight need to be towed out. If thevehicle does need to be towed out,seeTo w i n g t h e V e h i c l e0277.
Vehicle Load Limits
It is very important to know how
much weight the vehicle can
carry. This weight is called the
vehicle capacity weight and
includes the weight of all
occupants, cargo, and all
nonfactory-installed options.
Two labels on the vehicle may
show how much weight it may
properly carry: the Tire and
Loading Information label and
the Certification label.
{Warning
Do not load the vehicle any
heavier than the Gross
Vehicle Weight Rating
(GVWR), or either the
maximum front or rear Gross
Axle Weight Rating (GAWR).
This can cause systems to
break and change the way the
vehicle handles. This could
cause loss of control and a
crash. Overloading can also
reduce stopping distance,
damage the tires, and shorten
the life of the vehicle.

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 Park (Automatic
Tr a n s m i s s i o n )0187.
If you have to leave the vehicle withthe engine running, be sure thevehicle is in P (Park) and the
parking brake is firmly set beforeyou leave it. After you have movedthe shift lever into P (Park), hold thebrake pedal down. Then see if youcan move the shift lever away fromP(Park) without first pushing thebutton on the shift lever. If you can,it means that the shift lever was notfully locked into P (Park).
Torque Lock (Automatic
Transmission)
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.”To p r e v e n t t o r q u e l o c k , s e t t h eparking brake and then shift intoP(Park) properly before you leavethe driver seat. To find out how, see“Shifting Into Park”previously in thissection.
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, so you can pullthe shift lever out of P (Park).
Shifting out of Park
(Automatic Transmission)
This vehicle is equipped with a shiftlock control. The shift lock control isdesigned to:
.Prevent ignition key removalunless the shift lever is inP(Park) with the shift leverbutton fully released.
.Prevent movement of the shiftlever out of P (Park) unless theignition is in ON/RUN and thebrake pedal is applied.
The shift lock control is alwaysfunctional except in the case of anuncharged or low voltage (less than9-volt) battery.
