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°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.
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.

Scheduled Servicing — Diesel Engine
Your vehicle is equipped with an automatic
oil change indicator system. The oil change
indicator system will remind you that it is
time to take your vehicle in for engine oil
replacement.
Based on engine operation conditions, the oil
change indicator message will illuminate.
This means that service is required for your
vehicle. Operating conditions such as
frequent short-trips, trailer tow, extremely
hot or cold ambient temperatures will influ -
ence when the “Oil Change Required”
message is displayed. Severe Operating
Conditions can cause the change oil
message to illuminate as earlier than speci -
fied. Have your vehicle serviced as soon as
possible, within the next 500 miles
(805 km).
To help you have the best driving experience
possible, the manufacturer has identified the
specific vehicle maintenance service inter -
vals that are required to keep your vehicle
operating properly and safely. The manufacturer recommends that these
maintenance intervals be performed at your
selling dealer. The technicians at your deal
-
ership know your vehicle best, and have
access to factory trained information,
genuine Mopar parts, and specially designed
electronic and mechanical tools that can
help prevent future costly repairs.
NOTE:
The actual interval for changing engine oil
and replacing the engine oil filter depends
on the vehicle usage conditions, and is
signaled by the warning light or message in
the instrument panel. In any case, it must
never exceed 12,500 miles (20,000 km) or
12 months.
Flush and replace the engine coolant at
120 months or 150,000 miles (240,000 km)
whichever comes first.
The timing and accessory belts must be
changed every 37,500 miles (60,000 km) or
3 years for particularly demanding use
(dusty areas, severe weather conditions,
very low or very high temperatures for
extended periods, city driving, long periods
of idling). Under no circumstances should
these intervals be exceeded.

Cooling System
Engine Coolant Checks
Check the engine coolant (antifreeze) protec-
tion every 12 months (before the onset of
freezing weather, where applicable). If the
engine coolant (antifreeze) is dirty, the
system should be drained, flushed, and refilled with fresh OAT coolant (conforming
to MS.90032) by an authorized dealer.
Check the front of the A/C condenser for any
accumulation of bugs, leaves, etc. If dirty,
clean by gently spraying water from a garden
hose vertically down the face of the
condenser.
Check the engine cooling system hoses for
brittle rubber, cracking, tears, cuts, and
tightness of the connection at the coolant
recovery bottle and radiator. Inspect the
entire system for leaks. DO NOT REMOVE
THE COOLANT PRESSURE CAP WHEN THE
COOLING SYSTEM IS HOT.
Adding Washer Fluid
The windshield and rear window washers
share the same fluid reservoir. The fluid
reservoir is located in the front of the engine
compartment. Be sure to check the fluid
level in the reservoir at regular intervals. Fill
the reservoir with windshield washer solvent
(not radiator antifreeze) and operate the
system for a few seconds to flush out the
residual water.
When refilling the washer fluid reservoir,
take some washer fluid and apply it to a cloth
or towel and wipe clean the wiper blades,
this will help blade performance.To prevent freeze-up of your windshield
washer system in cold weather, select a solu
-
tion or mixture that meets or exceeds the
temperature range of your climate. This
rating information can be found on most
washer fluid containers.
Brake System
In order to ensure brake system perfor -
mance, all brake system components should
be inspected periodically. Refer to the
“Maintenance Plan” in this section for the
proper maintenance intervals.
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 open a cooling
system pressure cap when the radiator or
coolant bottle is hot.
Keep hands, tools, clothing, and jewelry
away from the radiator cooling fan when
the hood is raised. The fan starts auto-
matically and may start at any time,
whether the engine is running or not.
When working near the radiator cooling
fan, turn the ignition to the OFF mode.
The fan is temperature controlled and
can start at any time the ignition is in the
ON mode.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite
and burn you. Care must be exercised
when filling or working around the washer
solution.
CAUTION!
Do not travel with the windshield washer
fluid reservoir empty: the windshield
washer is essential for improving visibility.

Manual Transmission — If Equipped
Fluid Level Check
Check the fluid level by removing the fill
plug. The fluid level should be between the
bottom of the fill hole and a point not more
than 3/16 inch (4.7 mm) below the bottom
of the hole.
Add fluid, if necessary, to maintain the
proper level.
Please see your authorized dealer for service.
Automatic Transmission — If Equipped
Fluid Level Check
The fluid level is preset at the factory and
does not require adjustment under normal
operating conditions. Routine fluid level
checks are not required; therefore the trans-
mission has no dipstick. An authorized
dealer can check your transmission fluid
level using special service tools. If you notice
fluid leakage or transmission malfunction,
visit an authorized dealer immediately to
have the transmission fluid level checked.
Operating the vehicle with an improper fluid
level can cause severe transmission damage.
Maintenance-Free Battery
Your vehicle is equipped with a mainte -
nance-free battery. You will never have to
add water, nor is periodic maintenance
required.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately.
WARNING!
Using the battery with low fluid will
irreparably damage the battery and may
cause an explosion.
When performing any operation on the
battery or near it, always protect your
eyes with special goggles.
Batteries contain substances which are
very dangerous for the environment. For
battery replacement, contact an autho-
rized dealership.
Battery fluid is a corrosive acid solution
and can burn or even blind you. Do not
allow battery fluid to contact your eyes,
skin, or clothing. Do not lean over a
battery when attaching clamps. If acid
splashes in eyes or on skin, flush the
area immediately with large amounts of
water. Refer to “Jump Starting Proce-
dure” in “In Case Of Emergency” for
further information.
Battery gas is flammable and explosive.
Keep flame or sparks away from the
battery. Do not use a booster battery or
any other booster source with an output
greater than 12 Volts. Do not allow cable
clamps to touch each other.
Battery posts, terminals, and related
accessories contain lead and lead
compounds. Wash hands after handling.

Tire Spinning
When stuck in mud, sand, snow, or ice
conditions, do not spin your vehicle's wheels
above 30 mph (48 km/h) or for longer than
30 seconds continuously without stopping.
Refer to “Freeing A Stuck Vehicle” in “In
Case Of Emergency” for further information.
Tread Wear Indicators
Tread wear indicators are in the original
equipment tires to help you in determining
when your tires should be replaced.Tire Tread
These indicators are molded into the bottom
of the tread grooves. They will appear as
bands when the tread depth becomes a 1/16
of an inch (1.6 mm). When the tread is worn
to the tread wear indicators, the tire should
be replaced.
Refer to “Replacement Tires” in this section
for further information.
Life Of Tire
The service life of a tire is dependent upon
varying factors including, but not limited to:
Driving style.
Tire pressure - Improper cold tire inflation
pressures can cause uneven wear patterns
to develop across the tire tread. These
abnormal wear patterns will reduce tread
life, resulting in the need for earlier tire
replacement.
Distance driven.
Performance tires, tires with a speed
rating of V or higher, and Summer tires
typically have a reduced tread life. Rota-
tion of these tires per the vehicle sched -
uled maintenance is highly recommended.
WARNING!
Fast spinning tires can be dangerous.
Forces generated by excessive wheel
speeds may cause tire damage or failure. A
tire could explode and injure someone. Do
not spin your vehicle's wheels faster than
30 mph (48 km/h) for more than 30
seconds continuously when you are stuck,
and do not let anyone near a spinning
wheel, no matter what the speed.1 — Worn Tire
2 — New Tire
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can
result in sudden tire failure. You could lose
control and have a collision resulting in
serious injury or death.
