the parking brake. The transfer case N (NEUTRAL)
position disengages both the front and rear drive-
shafts from the powertrain and will allow the ve-
hicle to move regardless of the transmission posi-
tion. The parking brake should always be applied
when the driver is not in the vehicle.
CAUTION!
•Do not use a bumper mounted clamp-on tow bar
on your vehicle. The bumper face bar will be
damaged.
•Do not disconnect the rear driveshaft because

Tire Changing Procedure
WARNING!
Getting under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never get any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle is on a jack. If you need
to get under a raised vehicle, take it to a service
center where it can be raised on a lift.
Do not raise this vehicle using a bumper jack. The jack is
designed as a tool for changing tires on this vehicle only.
It is not recommended that the jack be used for service
purposes or to lift more than one wheel at a time.
Preparations
Park the vehicle on a firm level surface, avoiding ice or
slippery areas. Set the parking brake and place the gear
selector in PARK (automatic transmission) or REVERSE
(manual transmission). On four-wheel drive vehicles,
shift the transfer case to the “4L” position.
WARNING!
Do not attempt to change a tire on the side of the
vehicle close to moving traffic. Pull far enough off
the road to avoid the danger of being hit when
operating the jack or changing the wheel.

Attach the wheel wrench to the extension tube. Rotate the
winch mechanism until the wheel is drawn into place
against the underside of the vehicle. Continue to rotate
until you feel the winch mechanism slip or click 3 or 4
times. It cannot be overtightened. Push against the tire
several times to be sure it is firmly in place.
HOISTING
A conventional floor jack may be used at the jacking
locations, refer to the graphics that show jacking loca-
tions. However, a floor jack or frame hoist must never be
used on any other parts or the underbody.
CAUTION!
Never use a floor jack directly under the differential
housing of a loaded truck or damage to your vehicle
may result.
JUMP-STARTING
You should not try to start your vehicle by pushing or
towing. Vehicles equipped with an automatic transmis-
sion cannot be started this way and pushing or towing a
vehicle equipped with a manual transmission may over-
heat and damage the catalytic converter. Also, there is a
greater risk of an accident when a vehicle is being pushed
or towed. If the vehicle has a discharged battery, booster
cables may be used to obtain a start from a booster
battery or the battery in another vehicle. This type of start
can be dangerous if done improperly, so follow this
procedure carefully.

both vehicles, place the automatic transmission in Park or
the manual transmission in Neutral, and turn the ignition
OFF.
3. Turn off the heater, radio, and all unnecessary electri-
cal loads.
4. Connect one end of a jumper cable to the positive
terminal of the booster battery. Connect the other end of
the same cable to the positive terminal of the discharged
battery.
WARNING!
Do not permit vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
