negative battery post.
• Refer to your Owner's Manual on the DVD for further details.
CAUTION!
• Front or rear wheel lifts should notbe used. Internal damage to the
transmission or transfer case will
occur if a front or rear wheel lift is
used when recreational towing.
• Tow only in the forward direction. Towing this vehicle backwards can
cause severe damage to the
transfer case.
• Automatic transmissions must be placed in the PARK position for
recreational towing.
• Manual transmissions must be placed in gear (not in Neutral) for
recreational towing.
• Before recreational towing, perform the procedure outlined under
“Shifting Into NEUTRAL” to be
certain that the transfer case is
fully in NEUTRAL. Otherwise,
internal damage will result.
(Continued)
CAUTION!(Continued)
• Towing this vehicle in violation ofthe above requirements can cause
severe transmission and/or transfer
case damage. Damage from
improper towing is not covered
under the New Vehicle Limited
Warranty.
• Do not use a bumper-mounted clamp-on tow bar on your vehicle.
The bumper face bar will be
damaged.
• It is necessary to follow these steps to be certain that the transfer
case is fully in N (Neutral) before
recreational towing to prevent
damage to internal parts.
WARNING!
• You or others could be injured ifyou leave the vehicle unattended
with the transfer case in the N
(Neutral) position without first fully
engaging the parking brake. The
transfer case N (Neutral) position
disengages both the front and rear
driveshafts from the powertrain
and will allow the vehicle to move,
even if the transmission is in PARK.
The parking brake should always
be applied when the driver is not in
the vehicle.
UTILITY
53

• Raise the vehicle by turning the jackscrew clockwise. Raise the vehicle only
until the tire just clears the surface and
enough clearance is obtained to install
the spare tire.
• Remove the lug nuts and wheel.
• Position the spare wheel/tire on the vehicle and install the lug nuts with the
cone-shaped end toward the wheel.
Lightly tighten the lug nuts clockwise.
To avoid the risk of forcing the vehicle
off the jack, do not tighten the nuts fully
until the vehicle has been lowered.
• Lower the vehicle by turning the jack screw counterclockwise, and remove
the jack and wheel blocks.
• Finish tightening the lug nuts. Push down on the wrench while tightening for increased leverage. Alternate nuts until each one has been tightened twice. The
correct wheel nut tightness is 95 ft lbs (130 N•m). If in doubt about the correct
tightness, have them checked with a torque wrench by your authorized dealer or at
a service station.
• Secure the tire, jack, and tools in their proper locations.
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.
• 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. If you need to get under a raised vehicle, take
it to a service center where it can be raised on a lift.
• The jack is designed to use as a tool for changing tires only. The jack should not be used to lift the vehicle for service purposes. The vehicle should be
jacked on a firm, level surface only. Avoid ice or slippery areas.
• Carefully follow these tire changing procedures to help prevent personal injury or damage to your vehicle: Always park on a firm, level surface as far from the
edge of the roadway as possible before raising the vehicle.
• Raising the vehicle higher than necessary can make the vehicle less stable and could cause it to slip off the jack and hurt someone near it. Raise the vehicle
only enough to remove the tire.
• A loose tire or jack, thrown forward in a collision or hard stop, could endanger the occupants of the vehicle. Always stow the jack parts and the spare tire in
the places provided.
