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.
WARNING!
To avoid the risk of forcing the vehicle off the jack,
do not tighten the wheel nuts fully until the vehicle
has been lowered.
9. Lower the vehicle by turning the jack screw counter-
clockwise, 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 110 ft lbs (150 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 positions 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, properly secure the spare tire with thespecial wing nut torqued to 3.7 ft-lbs (5 N·m), reinstall the
jack and tool kit foam tray, and latch the rear load floor
cover.
WARNING!
A loose tire or jack, thrown forward in a collision or
hard stop could endanger the occupants of the ve-
hicle. Always stow the jack parts and the spare tire in
the places provided. Have the deflated (flat) tire
repaired or replaced immediately.
JUMP-STARTING
If 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.

WHAT TO DO IN EMERGENCIES 471

NOTE:When using a portable battery booster pack
follow the manufacturer’s operating instructions and
precautions.
CAUTION!
Do not use a portable battery booster pack or any
other booster source with a system voltage 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-Start
The battery in your vehicle is located under the passen-
ger’s front seat. There are remote locations located under
the hood to assist in jump-starting.
Remote Battery Posts
1 — Remote Positive (+) Post (covered with protective cap)
2 — Remote Negative (-) Post
472 WHAT TO DO IN EMERGENCIES

WARNING!
•Take care to avoid the radiator cooling fan when-
ever 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 unnecessary electri-
cal accessories. 3. Remove the protective cover over the remote 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 per-
sonal injury or property damage due to battery ex-
plosion.
6
WHAT TO DO IN EMERGENCIES 473

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 minutes, and then start
the engine in the vehicle with the discharged battery.
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 discharged vehicle.
7. Disconnect the negative end (-)of the jumper cable
from the negative (-)post of the booster battery.
474 WHAT TO DO IN EMERGENCIES

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 remote posi-
tive (+)battery post of the discharged vehicle.
If frequent jump-starting is required to start your vehicle
you should have the battery and charging system in-
spected 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 discharge sufficiently to degrade battery
life and/or prevent the engine from starting.
EMERGENCY TOW HOOKS — IF EQUIPPED
If your vehicle is equipped with tow hooks, there will be
one in the rear and two mounted on the front of the
vehicle. The rear hook will be located on the driver’s side
of the vehicle.
NOTE: For off-road recovery, it is recommended to use
both of the front tow hooks to minimize the risk of
damage to the vehicle.
WARNING!
•Chains are not recommended for freeing a stuck
vehicle. Chains may break, causing serious injury
or death.
•Stand clear of vehicles when pulling with tow
hooks. Tow straps and chains may break, causing
serious injury.

Tow hooks are for emergency use only, to rescue a
vehicle stranded off road. Do not use tow hooks for
tow truck hookup or highway towing. You could
damage your vehicle.

moved out of the PARK position, you can use the
following procedure to temporarily move the shift lever:
1. Firmly set the parking brake.
2. Turn the ignition switch to the ON/RUN position
without starting the engine.

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled
vehicle using a commercial wrecker service. If the trans-
mission and drivetrain are operable, disabled vehicles
may also be towed as described under “Recreational
Towing” in the “Starting and Operating” section.NOTE:
Vehicles equipped with Quadra-Lift™ must be
lowered to the Park (lowest) level, and have automatic
leveling disabled, before tying them down (from the
body) on a trailer or flatbed truck. Refer to the section on
Quadra-Lift™ for more information. If the vehicle cannot
be lowered to the Park level (for example, engine will not
run), tie-downs must be fastened to the axles (not to the
body). Failure to follow these instructions may cause
fault codes to be set and/or loss of proper tie-down
tension.

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 equip-
ment 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, defrosters, etc.)
while being towed, the ignition must be in the ON/RUN
position, not the ACC position.
