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.

CAUTION!
Closing the armrest while the Manual Park
Release is activated may damage the
Manual Park Release mechanism, the
transmission, and/or the armrest.
NOTE:
To prevent the vehicle from rolling uninten-
tionally, firmly apply the parking brake.To Disengage The Manual Park Release Le-
ver:
1. To disengage the Manual Park Release,
apply tension upward while pushing the
release latch towards the tether to unlock
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.

Proper towing or lifting equipment is required
to prevent damage to your vehicle. Use only
tow bars and other equipment designed for
this purpose, following equipment manufac-
turer’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 brack-
ets. State and local laws regarding 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 mode, not the ACC
mode.If the vehicle's battery is discharged, refer to
“Manual Park Release” in this section for
instructions on shifting the transmission out
of PARK for towing.
CAUTION!
• Do not use sling type equipment when
towing. Vehicle damage may occur.
• 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.
CAUTION!
• If the vehicle being towed requires steer-
ing, the ignition switch must be in the
ACC or ON/RUN mode, not in the LOCK/
OFF mode.
NOTE:
SRT vehicles and 4WD models without 4WD
LOW range should only be towed with all four
wheelsOFFthe ground.
IN CASE OF EMERGENCY
232

Without The Key Fob
Special care must be taken when the vehicle
is towed with the ignition in the LOCK/OFF
mode. The only approved method of towing
without the key fob is with a flatbed truck.
Proper towing equipment is necessary to pre-
vent damage to the vehicle.
Two-Wheel Drive Models
The manufacturer recommends towing your
vehicle with all four wheelsOFFthe ground
using a flatbed.
If flatbed equipment is not available, and the
transmission is operable, the vehicle may be
towed (with rear wheels on the ground) under
the following conditions:
• The transmission must be in NEUTRAL.
Refer to "Manual Park Release" in this sec-
tion for instructions on shifting the trans-
mission to NEUTRAL when the engine is
off.
• The towing speed must not exceed 30 mph
(48 km/h).
• The towing distance must not exceed
30 miles (48 km).If the transmission is not operable, or the
vehicle must be towed faster than 30 mph
(48 km/h) or farther than 30 miles (48 km),
tow with the rear wheelsOFFthe ground.
Acceptable methods are to tow the vehicle on
a flatbed, or with the front wheels raised and
the rear wheels on a towing dolly, or (when
using a suitable steering wheel stabilizer to
hold the front wheels in the straight position)
with the rear wheels raised and the front
wheels on the ground.
CAUTION!
• Towing faster than 30 mph (48 km/h) or
farther than 30 miles (48 km) with rear
wheels on the ground can cause severe
transmission damage. Damage from im-
proper towing is not covered under the
New Vehicle Limited Warranty.
Four-Wheel Drive Models
The manufacturer recommends towing with
all wheelsOFFthe ground. Acceptable meth-
ods 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, vehicles may be
towed (in the forward direction, withALL
wheels on the ground),IFthe transfer case is
in NEUTRAL (N) and the transmission is in
PARK. Refer to “Recreational Towing” in
“Starting And Operating” in the Owner’s
Manual for detailed instructions.
Vehicles equipped with a single-speed trans-
fer case have no NEUTRAL position, and
thereforemustbe towed with all four wheels
OFFthe ground.
CAUTION!
• Front or rear wheel lifts must not be used
(if the remaining wheels are on the
ground). Internal damage to the trans-
mission or transfer case will occur if a
233

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
Vehicle” section for further information.
• Please refer to the “Towing A Disabled
Vehicle” section for detailed instruc-
tions. Damage to your vehicle may occur
if these guidelines are not followed.
WARNING!
Stand clear of vehicles when pulling with
tow eyes.
• Do not use a chain with a tow eye.
Chains may break, causing serious in-
jury or death.
• Do not use a tow strap with a tow eye.
Tow straps may break or become disen-
gaged, causing serious injury or death.
• Failure to follow proper tow eye usage
may cause components to break result-
ing in serious injury or death.
• The brake and steering power assist sys-
tems will not function while the vehicle
is being towed. You will, therefore, need
to apply more force on the brake pedal
and steering wheel. Do not use flexible
ropes when towing, and avoid jerky
