Jack Usage Precautions
To complete the Use and Maintenance Hand-
book to which this supplement is attached,
given below are some instructions on the
proper use of the jack.
WARNING!
When using the crank, make sure it turns
freely without the risk of scraping hands
against the ground.
Even the moving parts of the jack, the
“worm screw” and joints can cause inju-
ries: avoid contact with them. Clean it
thoroughly if dirtied with grease.
CAUTION!
The jack is a tool designed exclusively for
changing a wheel, in case of a puncture or
damage to a tire of the vehicle on which it
is fitted or on vehicles of the same model.
Any other use, e.g. to jack up other vehicle
models or different things, is strictly pro-
hibited. Never use it to carry out mainte-
nance or repairs under the vehicle or to
CAUTION!
change summer/winter wheels and vice
versa. Never go under the raised vehicle. If
any work under the vehicle is necessary,
contact an authorized dealer. Incorrect
placing of the jack can cause the vehicle to
drop: use it only in the positions indicated.
Do not use the jack for loads higher than
that specified on the label. Never start the
engine with vehicle raised. If the vehicle is
raised more than necessary, everything
can become more unstable, with the risk of
the vehicle dropping violently. Therefore
raise the vehicle only as much as neces-
sary for the wheel/spare.
Maintenance
• Make sure grime does not build up on the
“worm screw.”
• Keep the “worm screw” lubricated.
• Never modify the jack.
Conditions Of Non-Use:
• Temperatures below −40°F (-40°C).
• On sandy or muddy ground.
• On uneven ground.• On steep roads.
• In extreme weather conditions: thunder-
storms, typhoons, hurricanes, blizzards,
storms, etc.
NOTE:
• The jack requires no adjustment.
• The jack cannot be repaired, and in the
event of a fault, it must be replaced by
another genuine one.
• No tool other than its cranking device may
be fitted on the jack.
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.
225

WARNING!
Do not attempt jump starting if the battery
is frozen. It could rupture or explode and
cause personal injury.
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.
NOTE:
When using a portable battery booster pack,
follow the manufacturer's operating instruc-
tions and precautions.
Preparations For Jump Start
The battery in your vehicle is located under
the passenger's front seat. There are remote
terminals located under the hood to assist in
jump starting.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.
WARNING!
• Remove any metal jewelry such as rings,
watch bands and bracelets that could
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.
NOTE:
Be sure that the disconnected cable ends do
not touch each other, or either vehicle, until
properly connected for jump starting.
1. Apply the parking brake, shift the auto-
matic transmission into PARK and turn
the ignition OFF.
2. Turn off the heater, radio, and all unnec-
essary electrical accessories.
3. Remove the protective cover over the re-
mote positive(+)battery post. Pull up-
ward on the cover to remove it.
Jump Starting Locations

(-) — Remote Negative Post
IN CASE OF EMERGENCY
226

4. If using another vehicle to jump start the
battery, park the vehicle within the jumper
cables reach, apply 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 connec-
tion and personal injury could result.
Jump Starting Procedure
WARNING!
Failure to follow this jump starting proce-
dure 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 ve-
hicle.NOTE:
Make sure at all times that unused ends of
jumper cables are not contacting each other
or either vehicle while making connections.
Connecting The Jumper Cables
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 jumper cable to the
negative (-) post of the discharged battery.
The resulting electrical spark could cause
the battery to explode and could result in
WARNING!
personal injury. Only use the specific
ground point, do not use any other exposed
metal parts.
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.
CAUTION!
Do not run the booster vehicle engine
above 2,000 rpm since it provides no
charging benefit, wastes fuel, and can
damage booster vehicle engine.
6. Once the engine is started, remove the
jumper cables in the reverse sequence:
Disconnecting The Jumper Cables
1. Disconnect the negative(-)end of the
jumper cable from the remote negative(-)
post of the discharged vehicle.
2. Disconnect the opposite end of the nega-
tive(-)jumper cable from the negative(-)
post of the booster battery.
227

3. Disconnect the positive(+)end of the
jumper cable from the positive(+)post of
the booster battery.
4. Disconnect the opposite end of the posi-
tive(+)jumper cable from the remote
positive(+)post of the discharged
vehicle.
5. Reinstall the protective cover over the
remote positive(+)post of the discharged
vehicle.
If frequent jump starting is required to start
your vehicle you should have the battery and
charging system tested at an authorized
dealer.
CAUTION!
Accessories plugged into the vehicle
power outlets draw power from the vehi-
cle’s battery, even when not in use (i.e.,
cellular devices, etc.). Eventually, if
plugged in long enough without engine
operation, the vehicle’s battery will dis-
charge sufficiently to degrade battery life
and/or prevent the engine from starting.
REFUELING IN EMERGENCY
The funnel for the Cap-Less Fuel System is
located in the spare tire storage area. If your
vehicle is out of fuel and an auxiliary fuel can
is needed, insert the funnel into the filler
neck and proceed to fill the vehicle.
For more information on the Cap-Less Fuel
System refer to “Refueling The Vehicle” in
“Starting And Operating”.
IF YOUR ENGINE
OVERHEATS
In any of the following situations, you can
reduce the potential for overheating by taking
the appropriate action.
• On the highways — slow down.
• In city traffic — while stopped, place the
transmission in NEUTRAL, but do not in-
crease the engine idle speed while prevent-
ing vehicle motion with the brakes.NOTE:
There are steps that you can take to slow
down an impending overheat condition:
• If your air conditioner (A/C) is on, turn it off.
The A/C system adds heat to the engine
cooling system and turning the A/C off can
help remove this heat.
• You can also turn the temperature control
to maximum heat, the mode control to floor
and the blower control to high. This allows
the heater core to act as a supplement to
the radiator and aids in removing heat from
the engine cooling system.WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool. Never try to open a cooling system
pressure cap when the radiator or coolant
bottle is hot.
IN CASE OF EMERGENCY
228

CAUTION!
Driving with a hot cooling system could
damage your vehicle. If the temperature
gauge reads HOT (H), pull over and stop
the vehicle. Idle the vehicle with the air
conditioner turned off until the pointer
drops back into the normal range. If the
pointer remains on HOT (H), and you hear
continuous chimes, turn the engine off
immediately and call for service.

ing the parking brake before activating the
Manual Park Release. In addition, you
should be seated in the driver’s seat with
your foot firmly on the brake pedal when
activating the Manual Park Release. Acti-
vating the Manual Park Release will allow
your vehicle to roll away if it is not secured
by the parking brake, or by proper connec-
tion to a tow vehicle. Activating the
WARNING!
Manual Park Release on an unsecured
vehicle could lead to serious injury or
death for those in or around the vehicle.
In order to move the vehicle in cases where

the lever.
2. Once the tension has been released and
the lever has been unlocked, be sure it is
stowed properly and locks into position.
NOTE:
Be sure to replace the cover by snapping it
back in place.
FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand
or snow, it can often be moved using a rock-
ing motion. Turn the steering wheel right and
left to clear the area around the front wheels.
Push and hold the lock button on the gear
selector. Then, shift back and forth between
DRIVE and REVERSE while gently pressing
the accelerator.NOTE:
Shifts between DRIVE and REVERSE can
only be achieved at wheel speeds of 5 mph
(8 km/h) or less. Whenever the transmission
remains in NEUTRAL for more than two sec-
onds, you must press the brake pedal to
engage DRIVE or REVERSE.
Use the least amount of accelerator pedal
pressure that will maintain the rocking mo-
tion without spinning the wheels or racing the
engine.
NOTE:
Push the "ESC Off" switch, to place the Elec-
tronic Stability Control (ESC) system in "Par-
tial Off" mode, before rocking the vehicle.
Refer to “Electronic Brake Control” in
“Safety” in your Owner’s Manual for further
information. Once the vehicle has been
freed, push the "ESC Off" switch again to
restore "ESC On" mode.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause damage, or even failure,

WARNING!
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.
CAUTION!
• Racing the engine or spinning the
wheels may lead to transmission over-
heating and failure. Allow the engine to
idle with the transmission in NEUTRAL
for at least one minute after every five
rocking-motion cycles. This will mini-
mize overheating and reduce the risk of
transmission failure during prolonged
efforts to free a stuck vehicle.
CAUTION!
• When “rocking” a stuck vehicle by shift-
ing between DRIVE 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 dam-
age the tires. Do not spin the wheels
above 30 mph (48 km/h) while in gear
(no transmission shifting occurring).
TOWING A DISABLED
VEHICLE
This section describes procedures for towing
a disabled vehicle using a commercial towing
service. If the transmission and drivetrain are
operable, disabled vehicles may also be
towed as described under “Recreational Tow-
ing” in the “Starting And Operating” section
of the Owner’s Manual.
NOTE:
Vehicles equipped with Quadra-Lift must be
placed in Transport mode, 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
placed in Transport mode (for example, en-
gine will not run), tie-downs should be fas-
tened over the tires using specific tire tie-
down nets. Failure to follow these
instructions may cause fault codes to be set
and/or cause loss of proper tie-down tension.
231

CAUTION!
front or rear wheel lift is used when
towing.
• Towing this vehicle in violation of the
above requirements can cause severe
transmission and/or transfer case dam-
age. Damage from improper towing is
not covered under the New Vehicle Lim-
ited Warranty.
Tow Eye Usage — If Equipped
Your vehicle is equipped with a tow eye that
can be used to move a disabled vehicle.
When using a tow eye be sure to follow the
“Tow Eye Usage Precautions” and the “Tow-
ing A Disabled Vehicle” instructions in this
section.Tow Eye Usage Precautions
CAUTION!
• The tow eye must only be used for road-
side emergencies. Use with an appropri-
ate device in accordance with highway
code (a rigid bar) to maneuver the ve-
hicle in preparation for transport via a
tow truck.
• The tow eye must not be used to move
the vehicle off the road or where there
are obstacles.
• Do not use the tow eyes for tow truck
hookup or highway towing.
• Do not use the tow eye to free a stuck
vehicle. Refer to the “Freeing A Stuck
