(Continued)
To provide you with maximum comfort in the
Automatic mode during cold start-ups, the
blower fan remains on low until the engine
warms up. The blower increases in speed and
transition into Auto mode.
Manual Operation Override
This system offers a full complement of
manual override features. The AUTO symbol
in the front ATC display will be turned off
when the system is being used in the manual
mode.
Operating Tips
Summer Operation
The engine cooling system must be
protected with a high-quality antifreeze
coolant to provide proper corrosion protec-
tion and to protect against engine over -
heating. OAT coolant (conforming to
MS.90032) is recommended.
Winter Operation

To ensure the best possible heater and
defroster performance, make sure the engine
cooling system is functioning properly and the
proper amount, type, and concentration of
coolant is used. Use of the Air Recirculation
mode during Winter months is not recom -
mended, because it may cause window fogging.

Vacation/Storage
Before you store your vehicle, or keep it out
of service (i.e., vacation) for two weeks or
more, run the air conditioning system at idle
for about five minutes, in fresh air with the
blower setting on high. This will ensure
adequate system lubrication to minimize the
possibility of compressor damage when the
system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in
mild, rainy, and/or humid weather. To clear
the windows, select Defrost or Mix mode and
increase the front blower speed. Do not use
the Recirculation mode without A/C for long
periods, as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in
front of the windshield, is free of obstruc -
tions, such as leaves. Leaves collected in the
air intake may reduce airflow, and if they
enter the plenum, they could plug the water
drains. In Winter months, make sure the air
intake is clear of ice, slush, and snow.
Cabin Air Filter
The climate control system filters out dust
and pollen from the air. Contact an autho -
rized dealer to service your cabin air filter,
and to have it replaced when needed. CAUTION!
Failure to follow these cautions can cause
damage to the heating elements:
Use care when washing the inside of the
rear window. Do not use abrasive window
cleaners on the interior surface of the
window. Use a soft cloth and a mild
washing solution, wiping parallel to the
heating elements. Labels can be peeled
off after soaking with warm water.
Do not use scrapers, sharp instruments,
or abrasive window cleaners on the inte-
rior surface of the window.
Keep all objects a safe distance from the
window.
CAUTION! (Continued)

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 supple-
ment to the radiator and aids in removing
heat from the engine cooling system.
GEAR SELECTOR OVERRIDE
If a malfunction occurs, and the gear
selector cannot be moved out of the PARK
position, you can use the following procedure
to temporarily move the gear selector:
1. Turn the engine OFF.
2. Apply the park brake.
3. Grasp the boot material rearward of thegear selector and pull up to carefully
separate the gear selector bezel and boot
assembly from the center console.
Gear Selector Bezel
4. Press and maintain firm pressure on the brake pedal. 5. Insert a small screwdriver or similar tool
down into the gear selector override
access hole (at the right rear corner of the
gear selector assembly), and push and
hold the override release lever down.
Gear Selector Override Access Hole
6. Move the gear selector to the NEUTRAL position.
7. The vehicle may then be started in NEUTRAL.
8. Reinstall the gear selector boot.
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.

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Correct servicing is crucial for guaranteeing a
long life for the car under the best condi-
tions. For this reason, Jeep has planned a
series of checks and services at fixed
distance intervals and, where provided, at
fixed time intervals, 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 redemption schedule.
Scheduled Servicing is offered by all autho -
rized dealerships according to fixed time or
mileage intervals. If, during each operation,
in addition to the ones scheduled, the need
arises for further replacements 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 between
one scheduled servicing operation and the next should be reduced. More frequent main
-
tenance 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 autho -
rized dealership of any small operating irreg -
ularities without waiting for the next service.

Diesel Engines
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.
The maintenance intervals shown should be
performed as indicated in this section. 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 12,000 miles (20,000km) or 1
year.
Flush and replace the engine coolant at
120 months or 150,000 miles (240,000 km)
whichever comes first.
Areas that are not dusty: recommended
maximum distance 75,000 mi
(120,000 km). The belt must be replaced
every 6 years, regardless of distance trav-
elled. Dusty areas and/or heavy conditions
(severe weather conditions, very low or very
high temperatures for extended periods,
urban driving, long periods of idling): the
recommended maximum distance is
37,500 mi (60,000 km). The belt must be
replaced every 4 years, regardless of
distance travelled.
