Jack Usage Precautions
To complete the Use and Maintenance
Handbook to which this supplement is
attached, given below are some instructions
on the proper use of the jack.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°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.
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
injuries: 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
prohibited. Never use it to carry out
maintenance or repairs under the vehicle
or to 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 necessary for the
wheel/spare.

FREEING A STUCK VEHICLE
If your vehicle becomes stuck in mud, sand
or snow, it can often be moved using a
rocking motion. Turn the steering wheel right
and left to clear the area around the front
wheels. For vehicles with automatic trans-
mission, push and hold the lock button on
the gear selector. Then, shift back and forth
between DRIVE (D) and REVERSE (R), while
gently pressing the accelerator. Use the least
amount of accelerator pedal pressure that
will maintain the rocking motion, without
spinning the wheels or racing the engine.
NOTE:
For vehicles with automatic transmission:
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 (N) for
more than two seconds, you must press
the brake pedal to engage DRIVE or
REVERSE.
Push the “ESC OFF” switch, to place the
Electronic Stability Control (ESC) system
in “Partial Off” mode, before rocking the
vehicle. Refer to “Electronic Brake Control
System” in “Safety” in your Owner’s Manual for further details. 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,
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 overheating
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
clutch or transmission failure during
prolonged efforts to free a stuck vehicle.
When “rocking” a stuck vehicle by
shifting between DRIVE/SECOND GEAR
and REVERSE, do not spin the wheels
faster than 15 mph (24 km/h), or drive -
train 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).
CAUTION! (Continued)

TOWING A DISABLED VEHICLE
This section describes procedures for towing a disabled vehicle using a commercial towing service. If the transmission and drivetrain are oper-
able, disabled vehicles may also be towed as described under “Recreational Towing” in the “Starting And Operating” section.

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 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 associ -
ated brackets. State and local laws regarding vehi -
cles under tow must be observed.

If you must use the accessories (wipers,
defrosters, etc.) while being towed, the igni -
tion must be in the ON/RUN position, not the
ACC position. If the vehicle's battery is discharged, refer to
“Manual Park Release” in this chapter for
instructions on shifting the automatic trans
-
mission out of PARK in order to move the
vehicle.

The manufacturer recommends towing with
all wheels OFF the ground. Acceptable
methods are to tow the vehicle on a flatbed
or with one end of the 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), IF the transfer case is
in NEUTRAL (N) and the transmission is in
PARK (P). Refer to “Recreational Towing” in
“Starting And Operating” for detailed
instructions.
Without The Key Fob
Special care must be taken when the vehicle
is towed with the ignition in the OFF mode.
The only approved method of towing without
the key fob is with a flatbed truck. Proper
towing equipment is necessary to prevent
damage to the vehicle.
Tow Eye Usage
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
“Towing A Disabled Vehicle” instructions in
this section.
The tow eyes are mounted below the front
and rear bumpers.
