SCHEDULED SERVICING
Scheduled Servicing — Non SRT
Correct servicing is crucial for guaranteeing a
long life for the car under the best conditions.
For this reason, Jeep has planned a series of
checks and services at fixed distance inter-
vals and, where provided, at fixed time inter-
vals, as described in the Scheduled Servicing
plan. To keep the car’s efficiency in tip-top
condition, in the following Scheduled Service
plan pages a few additional checks are listed
that should be carried out more frequently
with respect to the normal coupon redemp-
tion schedule. Scheduled Servicing is offered
by all authorized dealerships according to
fixed time or mileage intervals. If, during
each operation, in addition to the ones
scheduled, the need arises for further re-
placements or repairs, these may be carried
out with the owner's explicit agreement only.
The technicians at your dealership know your
vehicle best, and have access to factory
trained information, genuine Mopar parts,
and specially designed electronic and me-
chanical tools that can help prevent futurecostly repairs. If your car is used frequently
for towing, the interval between one sched-
uled servicing operation and the next should
be reduced. More frequent maintenance may
be needed for vehicles in severe operating
conditions, such as dusty areas and very
short trip driving.
NOTE:
Scheduled Servicing interventions are set out
by the Manufacturer. Failure to have them
carried out may invalidate the warranty. It is
advised to inform an authorized dealership of
any small operating irregularities without
waiting for the next service.
The oil change indicator system will remind
you that it is time to take your vehicle in for
scheduled maintenance.
In the instrument cluster an “Oil Change
Required” message will be displayed and a
single chime will sound, indicating that an oil
change is necessary.The oil change indicator message will illumi-
nate approximately 7,000 miles
(11,200 km) after the most recent oil change
was performed. Have your vehicle serviced as
soon as possible, within 500 miles (800 km).
NOTE:
• The oil change indicator message will not
monitor the time since the last oil change.
Change your vehicles oil if it has been
12 months since your last oil change even
if the oil change indicator message is NOT
illuminated.
• Change your engine oil more often if you
drive your vehicle off-road for an extended
period of time.
• Under no circumstances should oil change
intervals exceed 7,500 miles (12,000 km)
or 12 months, whichever comes first.
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change. If this scheduled
oil change is performed by someone other
than your authorized dealer the message can

WARNING!
• You can be badly injured working on or
around a motor vehicle. Do only service
work for which you have the knowledge
and the right equipment. If you have any
doubt about your ability to perform a
service job, take your vehicle to a com-
petent mechanic.
• Failure to properly inspect and maintain
your vehicle could result in a component
malfunction and effect vehicle handling
and performance. This could cause an
accident.
Severe Duty Conditions
(****) Change the engine oil and engine oil
filter at every 3,000 miles (5 000 km) or
3 months if using your vehicle under any of
the following severe duty conditions:
• Stop and go driving.
• Driving in dusty conditions.
• Short trips of less than 10 miles (16 km).
• Trailer towing.• Taxi, police, or delivery service (commercial
service).
• Off-road or desert operation.
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 scheduled
servicing.
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 fre-
quent short-trips, trailer tow, extremely hot or
cold ambient temperatures will influence
when the “Oil Change Required” message is
displayed.
Your authorized dealer will reset the oil
change indicator message after completing
the scheduled oil change. If a scheduled oil
change is performed by someone other than
your authorized dealer, the message can bereset by referring to the steps described un-
der “Instrument Cluster Display” in “Getting
To Know Your Instrument Panel” for further
information.
Engine Oil Filter Replacement
Residual oil in the housing may spill from the
housing when the new filter is installed if the
residual oil is not either removed from the
housing or enough time has not elapsed to
allow the oil to drain back into the engine.
When servicing the oil filter on this engine,
carefully remove the filter and use a suction
gun to remove any residual oil left in the
housing or wait about 30 minutes for the oil
to drain back into the engine.
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 ac-
cess to factory trained information, genuine
Mopar parts, and specially designed elec-

WARNING!
should be done by an experienced
technician.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components.
Such damage is not covered by the New
Vehicle Limited Warranty.
Air Conditioning Filter Replacement (A/C Air
Filter)
Refer to “Scheduled Servicing” in this sec-
tion for the proper maintenance intervals.
See an authorized dealer for service.
Windshield Wiper Blades
Clean the rubber edges of the wiper blades
and the windshield periodically with a sponge
or soft cloth and a mild nonabrasive cleaner.
This will remove accumulations of salt or road
film.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using
the wipers to remove salt or dirt from a dry
windshield.
Avoid using the wiper blades to remove frost
or ice from the windshield. Keep the blade
rubber out of contact with petroleum prod-
ucts such as engine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies de-
pending on geographical area and frequency
of use. Poor performance of blades may be
present with chattering, marks, water lines or
wet spots. If any of these conditions are
present, clean the wiper blades or replace as
necessary.The wiper blades and wiper arms should be
inspected periodically, not just when wiper
performance problems are experienced. This
inspection should include the following
points:
• Wear or uneven edges
• Foreign material
• Hardening or cracking
• Deformation or fatigue
If a wiper blade or wiper arm is damaged,
replace the affected wiper arm or blade with
a new unit. Do not attempt to repair a wiper
arm or blade that is damaged.
Front Wiper Blade Removal/Installation
CAUTION!
Do not allow the wiper arm to spring back
against the glass without the wiper blade
in place or the glass may be damaged.
1. Lift the wiper arm to raise the wiper blade
off of the glass, until the wiper arm is in
the full up position.
SERVICING AND MAINTENANCE

WARNING!
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 sec-
onds continuously when you are stuck, and
do not let anyone near a spinning wheel,
no matter what the speed.
Tread Wear Indicators
Tread wear indicators are in the original
equipment tires to help you in determining
when your tires should be replaced.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 ab-
normal wear patterns will reduce tread life,
resulting in the need for earlier tire replace-
ment.
• Distance driven.
• Performance tires, tires with a speed rating
of V or higher, and Summer tires typically
have a reduced tread life. Rotation of these
tires per the vehicle scheduled mainte-
nance is highly recommended.
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.
NOTE:
Wheel Valve Stem must be replaced as well
when installing new tires due to wear and tear
in existing tires.
Keep dismounted tires in a cool, dry place
with as little exposure to light as possible.
Protect tires from contact with oil, grease,
and gasoline.
Replacement Tires
The tires on your new vehicle provide a bal-
ance of many characteristics. They should be
inspected regularly for wear and correct cold
tire inflation pressures. The manufacturer
strongly recommends that you use tires
equivalent to the originals in size, quality and
performance when replacement is needed.
