SCHEDULED SERVICING
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 sched-
uled, the need arises for further replace-
ments 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 mechanical tools that
can help prevent future costly repairs. If your car
is used frequently for towing, the interval be-
tween one scheduled servicing operation and
the next should be reduced. More frequentmaintenance 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.
1.4L Gasoline Engine
NOTE:
Under no circumstances should oil change
intervals exceed 9,000 miles (15,000 km) or
12 months, whichever comes first.
Once A Month Or Before A Long Trip
• Check engine oil level.
• Check windshield washer fluid level.
• Check tire pressure and look for unusual
wear or damage. Rotate tires at the first
sign of irregular wear, even if it occurs
before the oil indicator system turns on.
•
Check the fluid levels of the coolant reservoir
and brake master cylinder, fill as needed.
• Check function of all interior and exterior
lights.
At Each Oil Change
• Change oil and filter.
• Rotate the tires.Rotate at the first sign of
irregular wear, even if it occurs before the oil
indicator system turns on.
• Inspect battery and clean and tighten ter-
minals as required.
• Inspect brake pads, shoes, rotors, drums,
hoses and park brake.
• Inspect engine cooling system protection
and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty
or off-road conditions.
Refer to the “Maintenance Plan” on the fol-
lowing page for the required maintenance
intervals.
CAUTION!
Failure to perform the required maintenance
items may result in damage to the vehicle.
231

Under normal operating conditions, the cata-
lytic converter will not require maintenance.
However, it is important to keep the engine
properly tuned to assure proper catalyst opera-
tion and prevent possible catalyst damage.
NOTE:
Intentional tampering with emissions control
systems can result in civil penalties being
assessed against you.
In unusual situations involving grossly mal-
functioning engine operation, a scorching
odor may suggest severe and abnormal cata-
lyst overheating. If this occurs, stop the ve-
hicle, turn off the engine and allow it to cool.
Service, including a tune-up to manufactur-
er's specifications, should be obtained imme-
diately.
To minimize the possibility of catalytic con-
verter damage:
• Do not interrupt the ignition when the
transmission is in gear and the vehicle is in
motion.
• Do not try to start the vehicle by pushing or
towing the vehicle.• Do not idle the engine with any ignition
components disconnected or removed,
such as when diagnostic testing, or for
prolonged periods during very rough idle or
malfunctioning operating conditions.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 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.
Coolant Checks
Check engine coolant (antifreeze) protection
every 12 months (before the onset of freezing
weather, where applicable). If the engine
coolant (antifreeze) is dirty or rusty in appear-
ance, the system should be drained, flushed
and refilled with fresh engine coolant (anti-
freeze). 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.
Cooling System Pressure Cap
The cap must be fully tightened to prevent
loss of engine coolant (antifreeze), and to
ensure that engine coolant (antifreeze) will
return to the radiator from the coolant expan-
sion bottle/recovery tank if so equipped.
The cap should be inspected and cleaned if
there is any accumulation of foreign material
on the sealing surfaces.

WARNING!
• Do not open hot engine cooling system.
Never add engine coolant (antifreeze)
when the engine is overheated. Do not
loosen or remove the cap to cool an
overheated engine. Heat causes pres-
sure to build up in the cooling system. To
prevent scalding or injury, do not remove
the pressure cap while the system is hot
or under pressure.
• Do not use a pressure cap other than the
one specified for your vehicle. Personal
injury or engine damage may result.
Brake System
In order to assure brake system performance,
all brake system components should be in-
spected periodically. Refer to the “Mainte-
nance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision. Driving with your
foot resting or riding on the brake pedal
can result in abnormally high brake tem-
peratures, excessive lining wear, and pos-
sible brake damage. You would not have
your full braking capacity in an emergency.
Brake Master Cylinder
The fluid in the master cylinder should be
checked when performing under hood ser-
vices or immediately if the “Brake Warning
Light” is illuminated.
Be sure to clean the top of the master cylin-
der area before removing the cap. If neces-
sary, add fluid to bring the fluid level up to
the requirements described on the brake
fluid reservoir. With disc brakes, fluid level
can be expected to fall as the brake pads
wear. Brake fluid level should be checked
when pads are replaced. However, low fluid
level may be caused by a leak and a checkup
may be needed.
Use only manufacturer's recommended brake
fluid. Refer to “Fluids And Lubricants” in
“Technical Specifications” for further information.
WARNING!
• Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri-
cants” in “Technical Specifications” for
further information. Using the wrong
type of brake fluid can severely damage
your brake system and/or impair its per-
formance. The proper type of brake fluid
for your vehicle is also identified on the
original factory installed hydraulic mas-
ter cylinder reservoir.
• To avoid contamination from foreign
matter or moisture, use only new brake
fluid or fluid that has been in a tightly
closed container. Keep the master cylin-
der reservoir cap secured at all times.
Brake fluid in a open container absorbs
moisture from the air resulting in a lower
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.
