WARNING!
Carefully follow these tire changing warn-
ings 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.
• Never start or run the engine with the
vehicle on a jack.
• 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. If you need to get under a
raised vehicle, take it to a service center
where it can be raised on a lift.
• Only use the jack in the positions indi-
cated and for lifting this vehicle during a
tire change.
WARNING!
• If working on or near a roadway, be
extremely careful of motor traffic.
• To assure that spare tires, flat or in-
flated, are securely stowed, spares must
be stowed with the valve stem facing the
ground.

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 the Fiat Service Network. Incor-
rect 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 neces-
sary, everything can become more un-
stable, with the risk of the vehicle drop-
ping violently. Therefore raise the vehicle
only as much as necessary 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°C.
• On sandy or muddy ground.• On uneven ground.
• On steep roads.
• In extreme weather conditions: thunder-
storms, typhoons, hurricanes, blizzards,
storms, etc.
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.
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
IN CASE OF EMERGENCY
160

CAUTION!
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 in the
right rear of the engine compartment, behind
the Power Distribution Center.
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.
• Remove any metal jewelry such as rings,
watch bands and bracelets that could
make an inadvertent electrical contact.
You could be seriously injured.
WARNING!
• 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. Apply the parking brake, shift the auto-
matic transmission into PARK (manual
transmission in NEUTRAL) and turn the
ignition to LOCK.
2. Turn off the heater, radio, and all unnec-
essary electrical accessories.
3. 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 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 a good engine ground
(exposed metal part of the discharged
vehicle’s engine) away from the battery
and the fuel injection system.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
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 2000 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 engine ground of
the vehicle with the discharged battery.
2. Disconnect the opposite end of the nega-
tive(-)jumper cable from the negative(-)
post of the booster battery.
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.
IN CASE OF EMERGENCY
162

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.
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, shift trans-
mission into NEUTRAL, but do not increase
engine idle speed.
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.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.

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 System”
in “Safety” in your Owner’s Manual for fur-
ther 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

• 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
Your vehicle is equipped with tow eyes that
are mounted below the front and rear bum-
pers.
Tow Eye Usage Precautions
NOTE:
• Ensure that the tow eye is properly
mounted.
• The tow eye is recommended for use with
an approved tow bar and or rope.
• Do not use the tow eye to pull the vehicle
onto a flatbed truck.• Do not use the tow eye to free a stuck
vehicle. Refer to “Freeing A Stuck Vehicle”
in this section for further information.
WARNING!
Stand clear of vehicles when pulling with
tow eyes.
• Do not use a chain with a tow eye.
Chains may break, causing serious injury
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.
CAUTION!
• The tow eye must be used exclusively for
roadside assistance operations. Only use
the tow eye with an appropriate device in
accordance with the highway code (a
rigid bar or rope) to flat tow the vehicle
for a short distance to the nearest ser-
vice location.
• Tow eyes MUST NOT be used to tow
vehicles off the road or where there are
obstacles.
• In compliance with the above condi-
tions, towing with a tow eye must take
place with two vehicles (one towing, the
other towed) aligned as much as pos-
sible along the same center line. Dam-
age to your vehicle may occur if these
guidelines are not followed.
