5. For a rear tire, place the jack and protective
cap in the slot on the rear tie-down bracket, just
forward of the rear tire (as indicated by the
triangular lift point symbol on the sill molding).
Do not raise the vehicle until you are sure
the jack is fully engaged.6. Raise the vehicle by turning the jack screw
clockwise. Raise the vehicle only until the tire
just clears the surface and enough clearance is
obtained to install the spare tire. Minimum tire
lift provides maximum stability.
WARNING!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off
the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.7. Remove the lug nuts and wheel.
8. Position the spare wheel/tire on the vehicle
and install the lug nuts with the cone-shaped
end toward the wheel. Lightly tighten the nuts.
To avoid the risk of forcing the vehicle off the
jack, do not tighten the nuts fully until the
vehicle has been lowered.
9. Lower the vehicle by turning the jack screw
counterclockwise, and remove the jack and
wheel blocks.
10. Finish tightening the lug nuts. Push down
on the wrench while tightening for increased
leverage. Alternate nuts until each nut 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.
11. Lower the jack to the fully closed position
and return it and the tools to the proper posi-
tions in the foam tray.

12. Securely store the road wheel and jack in
the cargo area.
13. Have the aluminum road wheel and tire
repaired as soon as possible and properly
secure the spare tire, jack and tool kit.
WARNING!
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.
JUMP-STARTINGIf your vehicle has a discharged battery it can
be jump-started using a set of jumper cables
and a battery in another vehicle or by using a
portable battery booster pack. Jump-starting
can be dangerous if done improperly so please
follow the procedures in this section carefully.
NOTE:
When using a portable battery booster pack
follow the manufacturer’s operating instruc-
tions and precautions.
CAUTION!
Do not use a portable battery booster pack or
any other booster source with a system volt-
age greater than 12 Volts or damage to the
battery, starter motor, alternator or electrical
system may occur.
WARNING!
Do not attempt jump-starting if the battery is
frozen. It could rupture or explode and cause
personal injury.
Preparations for Jump-StartThe battery in your vehicle is located under the
passenger’s front seat. There are remote loca-
tions located under the hood to assist in jump-
starting.
Stowed Spare
Remote Battery Posts
1 — Remote Positive(+) Post
(covered with protective cap)
2 — Remote Negative (-) Post
262

WARNING!
•Take care to avoid the radiator cooling fan
whenever the hood is raised. It can start
anytime the ignition switch is on. You can
be injured by moving fan blades.
• Remove any metal jewelry such as watch
bands or bracelets that might make an
inadvertent electrical contact. You could be
seriously injured.
• Batteries contain sulfuric acid that can burn
your skin or eyes and generate hydrogen
gas which is flammable and explosive.
Keep open flames or sparks away from the
battery.
1. Set the parking brake, shift the automatic
transmission into PARK and turn the ignition to
LOCK.
2. Turn off the heater, radio, and all unneces-
sary electrical accessories.
3. Remove the protective cover over the re-
mote positive (+)battery post. Pull upward on
the cover to remove it. 4. If using another vehicle to jump-start the
battery, park the vehicle within the jumper
cables reach, set the parking brake and make
sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as
this could establish a ground connection and
personal injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this procedure could result in
personal injury or property damage due to
battery explosion.
CAUTION!
Failure to follow these procedures could result
in damage to the charging system of the
booster vehicle or the discharged vehicle.
1. Connect the positive
(+)end of the jumper
cable to the remote positive (+)post of the
discharged vehicle.
2. Connect the opposite end of the positive (+)
jumper cable to the positive (+)post of the
booster battery.
3. Connect the negative end (-)of the jumper
cable to the negative (-)post of the booster
battery.
4. Connect the opposite end of the negative (-)
jumper cable to the remote negative (-)post of
the vehicle with the discharged battery.
WARNING!
Do not connect the cable to the negative post
(-) of the discharged battery. The resulting
electrical spark could cause the battery to
explode and could result in personal injury.
5. Start the engine in the vehicle that has the
booster battery, let the engine idle a few min-
utes, and then start the engine in the vehicle
with the discharged battery.
263

Once the engine is started, remove the jumper
cables in the reverse sequence:
6. Disconnect the negative(-)jumper cable
from the remote negative (-)post of the dis-
charged vehicle.
7. Disconnect the negative end (-)of the
jumper cable from the negative (-)post of the
booster battery.
8. Disconnect the opposite end of the positive
(+) jumper cable from the positive (+)post of
the booster battery.
9. Disconnect the positive (+)end of the
jumper cable from the remote positive (+)post
of the discharged vehicle.
10. Reinstall the protective cover over the re-
mote positive (+)battery post of the discharged
vehicle. If frequent jump-starting is required to start your
vehicle you should have the battery and charg-
ing system inspected at your authorized dealer.
CAUTION!
Accessories that can be plugged into the
vehicle power outlets draw power from the
vehicle’s battery, even when not in use (i.e.,
cellular phones, etc.). Eventually, if plugged in
long enough, the vehicle’s battery will dis-
charge sufficiently to degrade battery life
and/or prevent the engine from starting.
TOW EYESYour vehicle is equipped with tow eyes, which
are mounted in the front and the rear.
CAUTION!
Tow eyes are for emergency use only, to
rescue a vehicle stranded off road. Do not use
tow eyes for tow truck hookup or highway
towing. You could damage your vehicle. Tow
straps are recommended when towing the
vehicle; chains may cause vehicle damage.
WARNING!
Stand clear of vehicles when pulling with tow
eyes. Tow straps and chains may break, caus-
ing serious injury.

TOWING A DISABLED VEHICLEThis section describes procedures for towing a disabled vehicle using a commercial wrecker service. If the transmission and drivetrain are operable,
disabled vehicles may also be towed as described under “Recreational Towing” in the “Starting and Operating” section.
Towing Condition Wheels OFF the Ground 4WD Models
Flat Tow NONE See instructions in “Recreational Towing” under “Starting and Operating”
•
Trans in PARK
• T/case in NEUTRAL
• To w i n forward direction
Wheel Lift or Dolly Tow Front
NOT ALLOWED
Rear NOT ALLOWED
Flatbed ALL BEST METHOD
Proper towing or lifting equipment is required to
prevent damage to your vehicle. Use only tow
bars and other equipment designed for the
purpose, following equipment manufacturer’s
instructions. Use of safety chains is mandatory.
Attach a tow bar or other towing device to main
structural members of the vehicle, not to
bumpers or associated brackets. State and
local laws applying to vehicles under tow must
be observed. If you must use the accessories (wipers, de-
frosters, etc.) while being towed, the ignition
must be in the ON/RUN position, not the ACC
position.
If the vehicle’s battery is discharged, see
Brake/Transmission Interlock Manual Override
(under Starting and Operating, Automatic
Transmission) for instructions on shifting the
automatic transmission out of the PARK posi-
tion for towing.
CAUTION!
•
Do not attempt to use sling type equipment
when towing. When securing the vehicle to
a flat bed truck, do not attach to front or rear
suspension components. Damage to your
vehicle may result from improper towing.
• If the vehicle being towed requires steering,
the ignition must be in the ON/RUN or ACC
position, not in the LOCK position.
265

Towing Without the Ignition Key FobSpecial care must be taken when the vehicle is
towed with the ignition in the LOCK position.
The only approved method of towing without
the ignition key is with a flatbed truck. Proper
towing equipment is necessary to prevent
damage to the vehicle.Four-Wheel Drive VehiclesThe manufacturer recommends towing with all
wheelsOFFthe ground. Acceptable methods
are to tow the vehicle on a flatbed or with one
end of vehicle raised and the opposite end on
a towing dolly.
If flatbed equipment is not available, and the
transfer case is operable, the vehicle may be
towed (in the forward direction, with ALL
wheels on the ground), IFthe transfer case is in
NEUTRAL and the transmission is in PARK.
Refer to “Recreational Towing” in “Starting and
Operating” for further information.CAUTION!
• Front or rear wheel lifts should not be used.
Internal damage to the transmission or
transfer case will occur if a front or rear
wheel lift is used when towing.
• Failure to follow these towing methods
could result in damage to the transmission
and/or transfer case. Such damage is not
covered by the New Vehicle Limited War-
ranty.
