4. Operate the jack from the front or the rear of the vehicle. Place the jack under the
axle tube, as shown. Do not raise the vehicle until you are sure the jack is fully
engaged.
5.
Raise the vehicle by turning the jack
screw to the right. 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.
6. Remove the lug nuts and wheel.
7. 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.
8. Lower the vehicle by turning the jack
screw to the left, and remove the jack.
9. 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 ser-
vice station.
10.
Remove the jack assembly and wheel
blocks.
11. Secure the tire, jack, and tools in
their proper locations.
12. Remove blocks from wheels.

Road Tire Installation 1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the cone shaped end of the nut toward the
wheel. Lightly tighten the lug nuts.
3. Lower the vehicle to the ground by turning the jack handle counterclockwise.
4. Finish tightening the lug nuts. Push down on the wrench while at the end of the
handle for increased leverage. Tighten the lug nuts in a star pattern until each nut
has been tightened twice. The correct tightness of each lug nut 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 service station.
5. After 25 miles (40 km) check the lug nut torque with a torque wrench to ensure
that all lug nuts are properly seated against the wheel.
CAUTION!Do not attempt to raise the vehicle by jacking on locations other than those
indicated in the Jacking Instructions for this vehicle.
WHAT TO DO IN EMERGENCIES
105

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.
• Being under a jacked-up vehicle is dangerous. The vehicle could slip off the
jack and fall on you. You could be crushed. Never put 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.
• Never start or run the engine while the vehicle is on a jack.
• The jack is designed to be used 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 warnings 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.
• Turn on the Hazard Warning flasher.
• Block the wheel diagonally opposite the wheel to be raised.
• Set the parking brake firmly and set an automatic transmission in PARK;
a manual transmission in REVERSE.
• Do not let anyone sit in the vehicle when it is on a jack.
• Do not get under the vehicle when it is on a jack.
• Only use the jack in the positions indicated and for lifting this vehicle
during a tire change.
• If working on or near a roadway, be extremely careful of motor traffic.
• To assure that spare tires, flat or inflated, are securely stowed, spares
must be stowed with the valve stem facing the ground.
• Raising the vehicle higher than necessary can make the vehicle less
stable and cause a collision. It could slip off the jack and hurt someone
near it. Raise the vehicle only enough to remove the tire.
• To avoid the risk of forcing the vehicle off the jack, do not tighten the
wheel nuts fully until the vehicle has been lowered.
• A loose tire or jack, thrown forward in a collision or hard stop, could en-
danger the occupants of the vehicle. Always stow the jack parts and the
spare tire in the places provided.
• To avoid the risk of forcing the vehicle off the jack, do not tighten the lug
nuts fully until the vehicle is lowered to the ground.WHAT TO DO IN EMERGENCIES

JUMP-STARTING • If your vehicle has a discharged bat-
tery it can be jump-started using a set
of jumper cables and a battery in an-
other 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
instructions and precautions.
Preparations for Jump-Start • The battery in your vehicle is located in the right rear of the engine compartment.
• Set the parking brake, shift the automatic transmission into PARK and turn the
ignition to LOCK.
• Turn off the heater, radio, and all unnecessary electrical accessories.
• 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.
Jump-Starting Procedure • Connect the positive (+) end of the jumper cable to the positive (+) post of the
discharged vehicle.
• Connect the opposite end of the positive (+) jumper cable to the positive (+) post
of the booster battery.
• Connect the negative end (-) of the jumper cable to the negative (-) post of the
booster battery.
• Connect the opposite end of the negative (-) jumper cable to a good engine ground
(exposed metal part of the discharged vehicle’s engine) away from the battery and
the fuel injection system.
• 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.WHAT TO DO IN EMERGENCIES
107

Once the engine is started, remove the jumper cables in the reverse sequence:
• Disconnect the negative (-) jumper cable from the engine ground of the vehicle
with the discharged battery.
• Disconnect the negative end (-) of the jumper cable from the negative (-) post of
the booster battery.
• Disconnect the opposite end of the positive (+) jumper cable from the positive (+)
post of the booster battery.
• Disconnect the positive (+) end of the jumper cable from the positive (+) post of
the discharged vehicle.
• If frequent jump-starting is required to start your vehicle you should have the
battery and charging system inspected at your authorized dealer.
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.
• Failure to follow these procedures could result in damage to the charging
system of the booster vehicle or the discharged vehicle.
• 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 discharges suffi-
ciently to degrade battery life and/or prevent the engine from starting.
WARNING!• When temperatures are below the freezing point, electrolyte in a discharged battery
may freeze. Do not attempt jump-starting because the battery could rupture or
explode and cause personal injury. Battery temperature must be brought above the
freezing point before attempting a jump-start.
• 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 severely 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.
• Do not allow vehicles to touch each other as this could establish a ground
connection and personal injury could result.
• Failure to follow this procedure could result in personal injury or property damage
due to battery explosion.
• 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.WHAT TO DO IN EMERGENCIES

EMERGENCY TOW HOOKS • If your vehicle is equipped with tow hooks, they are mounted in the front and the rear.
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.
CAUTION!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. Tow straps are recommended when towing the vehicle; chains may cause
vehicle damage.
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 may become
disengaged, causing serious injury.
SHIFT LEVER OVERRIDE • If a malfunction occurs and the shift
lever cannot be moved out of the PARK
position, you can use the following
procedure to temporarily move the
shift lever:
• To access the shift lever override,
remove the override cover located on
the shift lever bezel, next to the shift
lever.
• Firmly set the parking brake.
• Turn the ignition switch to the ACC
or ON position without starting the
engine.
• Press and maintain firm pressure on
the brake pedal.
• Using a screwdriver or similar tool, press and hold the override tab through the
access port on the center console.
• Move the shift lever into the NEUTRAL position.
• The vehicle may then be started in NEUTRAL.
• Reinstall the override cover.WHAT TO DO IN EMERGENCIES
109

TOWING A DISABLED VEHICLE • The manufacturer requires towing your vehicle with all four wheels OFF the ground
using a flatbed.
CAUTION!Towing this vehicle using any other method could result in extensive damage to the
transfer case and/or transmission.
FREEING A STUCK VEHICLE • If your vehicle becomes stuck in mud, sand or snow, it can often be moved by a
rocking motion. Turn your steering wheel right and left to clear the area around the
front wheels. Then shift back and forth between DRIVE/1st gear and REVERSE.
Using minimal accelerator pedal pressure to maintain the rocking motion, without
spinning the wheels, is most effective.
NOTE:
If your vehicle is equipped with Traction Control or Electronic Stability Control (ESC),
turn the system OFF before attempting to “rock” the vehicle.
CAUTION!• Racing the engine or spinning the wheels may lead to transmission overheating
and failure. Allow the engine to idle with the shift lever in NEUTRAL for at least
one minute after every five rocking-motion cycles. This will minimize overheat-
ing and reduce the risk of transmission failure during prolonged efforts to free
a stuck vehicle.
• When “rocking” a stuck vehicle by moving between DRIVE/1st gear and
REVERSE, do not spin the wheels faster than 15 mph (24 km/h), or drivetrain
damage may result.
• Revving the engine or spinning the wheels too fast may lead to transmission
overheating and failure. It can also damage the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear (no transmission shifting occurring).
WARNING!Fast spinning tires can be dangerous. Forces generated by excessive wheel speeds
may cause damage, or even failure, of the axle and tires. A tire could explode and
injure someone. Do not spin your vehicle's wheels faster than 30 mph (48 km/h)
or for longer than 30 seconds continuously without stopping when you are stuck
and do not let anyone near a spinning wheel, no matter what the speed.WHAT TO DO IN EMERGENCIES
