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

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

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

boiling point. This may cause it to boil
unexpectedly during hard or prolonged
braking, resulting in sudden brake fail-
ure. This could result in a collision.
• Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot en-
gine parts, causing the brake fluid to
catch fire. Brake fluid can also damage
painted and vinyl surfaces, care should
be taken to avoid its contact with these
surfaces.
• Do not allow petroleum based fluid to
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This
could result in a collision.
Automatic Transmission
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 dealercan check your transmission fluid level using
special service tools. If you notice fluid leak-
age or transmission malfunction, visit an au-
thorized dealer immediately to have the
transmission fluid level checked. Operating
the vehicle with an improper fluid level can
cause severe transmission damage.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An au-
thorized dealer has the proper tools to
adjust the fluid level accurately.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-
free battery. You will never have to add water,
nor is periodic maintenance required.
WARNING!
• Using the battery with low fluid will
irreparably damage the battery and may
cause an explosion.
WARNING!
• 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.
