MAINTENANCE PROCEDURES
The pages that follow contain therequiredmaintenance
services determined by the engineers who designed your
vehicle.
Besides those maintenance items specified in the fixed
“Maintenance Schedule”, there are other components
which may require servicing or replacement in the future.
CAUTION!
• Failure to properly maintain your vehicle or perform
repairs and service when necessary could result in
more costly repairs, damage to other components or
negatively impact vehicle performance. Immediately
have potential malfunctions examined by an autho-
rized dealer or qualified repair center.
• Your vehicle has been built with improved fluids
that protect the performance and durability of your
vehicle and also allow extended maintenance inter-
vals. Do not use chemical flushes in these compo-
nents as the chemicals can damage your engine,
transmission, or air conditioning. Such damage is not
covered by the New Vehicle Limited Warranty. If a
(Continued)

flush is needed because of component malfunction,
use only the specified fluid for the flushing proce-
dure.
Engine Oil
Checking Oil Level
To assure proper engine lubrication, the engine oil must be
maintained at the correct level. Check the oil level at
regular intervals, such as every fuel stop. The best time to
check the oil level is approximately five minutes after a
fully warmed engine is shut off. Do not check oil level
before starting the engine after it has sat overnight. Check-
ing engine oil level when the engine is cold will give you
an incorrect reading.
Checking the oil while the vehicle is on level ground also
will improve the accuracy of the oil level readings. Add oil
only when the level is below the SAFE mark.
CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.

CAUTION!(Continued)
•If a “fast charger” is used while the battery is in the
vehicle, disconnect both vehicle battery cables before
connecting the charger to the battery. Do not use a
“fast charger” to provide starting voltage.
Hibernation Mode
The Hibernation mode feature conserves battery power
when storing the vehicle. It allows for up to three months
of storage time without losing radio and engine controller
adaptive memory. Using this feature is an alternative to
disconnecting the battery.
NOTE: This vehicle is designed to sit in storage with a
fully charged battery for up to 30 days. If you plan to store
the vehicle longer than 30 days, we recommend doing one
of the following:
• Disconnect the battery.
• Use the battery charger.
• Put the vehicle into Hibernation mode (3-month charge).
To Activate Hibernation Mode
1. Cycle the ignition switch to (ACC).
2. Select Hibernation mode within the instrument cluster
display.
3. Push the right arrow button on the steering wheel controls for one second. Vehicle will countdown from
ten seconds and enter Hibernation Mode.
NOTE: You may push the right arrow button on the
steering wheel controls during the countdown to abort
Hibernation Mode.
To Deactivate Hibernation Mode
1. Push the key fob UNLOCK button to unlock the vehicle.
2. Push the ignition switch to the ON/RUN position.
Air Conditioner Maintenance
For best possible performance, your air conditioner should
be checked and serviced by an authorized dealer at the
start of each warm season. This service should include
cleaning of the condenser fins and a performance test.
Drive belt tension should also be checked at this time.

MAINTAINING YOUR VEHICLE 271

The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant, such as MOPAR Lock
Cylinder Lubricant directly into the lock cylinder.
Wiper Blades
Clean the rubber edges of the wiper blades, the windshield,
and rear window periodically with a sponge or soft cloth
and a mild nonabrasive cleaner. This will remove accumu-
lations of salt, waxes, or road film, and help reduce
streaking and smearing.
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 or rear window.
Avoid using the wiper blades to remove frost or ice from
the windshield or rear window. Make sure that they are not
frozen to the glass before turning them on to avoid
damaging the blade. Keep the wiper blade out of contact
with petroleum products such as engine oil, gasoline, etc.NOTE:
Life expectancy of wiper blades varies depending
on geographical area and frequency of use. Poor perfor-
mance 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.Adding Washer Fluid
The windshield washer fluid reservoir is located in the
front of the engine compartment on the passenger side of
the vehicle. Be sure to check the fluid level in the reservoir
at regular intervals. Fill the reservoir with windshield
washer solvent (not engine coolant (antifreeze) and operate
the system for a few seconds to flush out the residual
water.
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.

Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to assure proper catalyst
operation and prevent possible catalyst damage.
NOTE:Intentional tampering with emissions control sys-
tems can result in civil penalties being assessed against
you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter damage:
• Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
• Do not try to start the engine by pushing or towing the
vehicle.
• Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.Cooling System
WARNING!
• When working near the radiator cooling fan, discon-
nect the fan motor lead or cycle the ignition switch to
the LOCK position. The fan is temperature con-
trolled and can start at any time the ignition switch is
in the ON position.
• 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 is hot.
Coolant Checks
Check engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where appli-
cable). 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/radiator 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/radiator.

MAINTAINING YOUR VEHICLE 275

Check the coolant recovery bottle tubing for brittle rubber,
cracking, tears, cuts, and tightness of the connection at the
bottle and radiator. Inspect the entire system for leaks. DO
NOT REMOVE THE COOLANT PRESSURE CAP WHEN
THE COOLING SYSTEM IS HOT.
Cooling System — Drain, Flush And Refill
NOTE:Some vehicles require special tools to add coolant
properly. Failure to fill these systems properly could lead to
severe internal engine damage. If any coolant is needed to
be added to the system, please contact your local autho-
rized dealer.
If the engine coolant (antifreeze) is dirty or contains visible
sediment, have an authorized dealer clean and flush with
OAT coolant (antifreeze) (conforming to MS.90032).
Refer to the “Maintenance Schedule” for the proper main-
tenance intervals.
Selection Of Coolant
Refer to “Fluids, Lubricants, And Genuine Parts” in “Main-
taining Your Vehicle” for further information.
CAUTION!
• Mixing of engine coolant (antifreeze) other than
specified Organic Additive Technology (OAT) en-
gine coolant (antifreeze), may result in engine dam-
age and may decrease corrosion protection. Organic
Additive Technology (OAT) engine coolant is differ-
ent and should not be mixed with Hybrid Organic
Additive Technology (HOAT) engine coolant (anti-
freeze) or any “globally compatible” coolant (anti-
freeze). If a non-OAT engine coolant (antifreeze) is
introduced into the cooling system in an emergency,
the cooling system will need to be drained, flushed,
and refilled with fresh OAT coolant (conforming to
MS.90032), by an authorized dealer as soon as pos-
sible.
• Do not use water alone or alcohol-based engine
coolant (antifreeze) products. Do not use additional
rust inhibitors or antirust products, as they may not
be compatible with the engine coolant and may plug
the radiator.
• This vehicle has not been designed for use with
propylene glycol-based engine coolant (antifreeze).
Use of propylene glycol-based engine coolant (anti-
freeze) is not recommended.
276 MAINTAINING YOUR VEHICLE

Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to insure that engine coolant
(antifreeze) will return to the radiator from the coolant
recovery bottle.
The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.
WARNING!
•The warning words “DO NOT OPEN HOT” on the
cooling system pressure cap are a safety precaution.
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 speci-
fied for your vehicle. Personal injury or engine
damage may result.
Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (antifreeze) is a
regulated substance requiring proper disposal. Check with your local authorities to determine the disposal rules for
your community. To prevent ingestion by animals or
children, do not store ethylene glycol-based engine coolant
(antifreeze) in open containers or allow it to remain in
puddles on the ground. If ingested by a child or pet, seek
emergency assistance immediately. Clean up any ground
spills immediately.
Coolant Level
The coolant bottle provides a quick visual method for
determining that the coolant level is adequate. With the
engine OFF and cold, the level of the engine coolant
(antifreeze) in the bottle should be between the ranges
indicated on the bottle.
The radiator normally remains completely full, so there is
no need to remove the radiator/coolant pressure cap
unless checking for engine coolant (antifreeze) freeze point
or replacing coolant. Advise your service attendant of this.
As long as the engine operating temperature is satisfactory,
the coolant bottle need only be checked once a month.
When additional engine coolant (antifreeze) is needed to
maintain the proper level, only OAT coolant that meets the
requirements of FCA Material Standard MS.90032 should
be added to the coolant bottle. Do not overfill.
278 MAINTAINING YOUR VEHICLE

Points To Remember
NOTE:When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is normally
a result of moisture from rain, snow, or high humidity
accumulating on the radiator and being vaporized when
the thermostat opens, allowing hot engine coolant (anti-
freeze) to enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
• Do not overfill the coolant expansion bottle.
• Check the coolant freeze point in the radiator and in the
coolant expansion bottle. If engine coolant (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
• If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
•
Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to MS.90032)
and distilled water for proper corrosion protection of your
engine which contains aluminum components.
• Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
• Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake System
To ensure brake system performance, all brake system com-
ponents should be inspected periodically. Refer to “Mainte-
nance Schedule” for the proper maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly an accident. Driving with your foot resting or
riding on the brake pedal can result in abnormally
high brake temperatures, excessive lining wear, and
possible brake damage. You would not have your full
braking capacity in an emergency.

Master Cylinder — Brake Fluid Level Check
Check the fluid level in the master cylinder immediately if
the brake system warning light indicates system failure.
Check the fluid level in the master cylinder when perform-
ing underhood services.
Clean the top of the master cylinder area before removing
the cap. If necessary, add fluid to bring the fluid level up to
the requirements described on the brake fluid reservoir.
Overfilling of fluid is not recommended because it may
cause leaking in the system.
With disc brakes, fluid level can be expected to fall as the
brake pads wear. However, low fluid level may be caused
by a leak and a checkup may be needed.
Use only the manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in “Main-
taining Your Vehicle” for further information. Use of a
brake fluid that may have a lower initial boiling point or
unidentified as to specification, may result in sudden brake
failure during hard prolonged braking.
WARNING!
•Use only manufacturer ’s recommended brake fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Using the wrong type of brake fluid can severely
damage your brake system and/or impair its perfor-
mance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.
• To avoid contamination from foreign matter or mois-
ture, 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 brak-
ing, resulting in sudden brake failure. This could
result in a accident.
• Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine 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.

the vehicle’s battery. If the vehicle is not going to be
driven in the next three weeks, perform the battery
recharge procedure in the Service Manual. Then, either
disconnect the battery at the negative terminal or use
“Hibernation Mode” to conserve battery power. Refer to
“Maintenance Procedures/Hibernation Mode” in
“Maintaining Your Vehicle” for further information.
• Cover the vehicle whenever possible to prevent acciden-
tal damage to the finish.
NOTE: Disconnecting the battery causes the engine control
system to lose memory of some “learned” functions. After
reconnecting the battery, the engine may run rough until
the control module “relearns” these functions. Using the
Battery Save Feature will prevent the engine controller
from loosing its memory.
CAUTION!
Use care when disconnecting the remote positive cable.
It is connected to the battery and can short out to any
metal on the vehicle. Always tape or wrap the exposed
cable end to prevent electrical shorts.
Check the battery every four to six weeks to ensure that the
voltage is above 12.10 Volts. The voltage will drop more rapidly in hot temperatures. If battery voltage drops below
12.10 Volts, follow the battery recharge procedure in the
Service Manual.
NOTE:
To help prevent the battery from discharging dur-
ing shorter periods of inactivity, perform the following:
1. Make sure that the liftgate, hood, doors, windows are completely closed.
2. Make sure that the key fob is operating and that the battery is good.
3. Make sure that the HOOD, LIFTGATE, and DOOR switches are in adjustment. Perform the quick system
check, which follows:
Use the key fob to set the alarm. If the alarm SET light
comes on and flashes, the system is operating properly. If
not, there is a problem with a switch or the system. See
your authorized dealer for service.
If you plan to store the vehicle longer than 30 days, we
recommend using Hibernation Mode to conserve battery
power. Refer to “Hibernation Mode” in Maintenance
Procedures for further information.

vals exceed 6,000 miles (10 000 km) or six months,
whichever comes first.
CAUTION!
Failure to perform the required maintenance items
may result in damage to the vehicle.At Each Stop For Fuel
•
Check the engine oil level about five minutes after a
fully warmed engine is shut off. Checking the oil level
while the vehicle is on level ground will improve the
accuracy of the oil level reading. Add oil only when the
level is at or below the ADD or MIN mark.
• Check the windshield washer solvent, and add if re-
quired.
Once A Month
• Check tire pressure and look for unusual wear or
damage. Rotate tires at the first sign of irregular wear,
even if it occurs before your next scheduled service.
• Inspect the battery, and clean and tighten the terminals
as required.
• Check the fluid levels of the coolant reservoir, brake
master cylinder, power steering, and transmission, and
add as needed.
• Check all lights and all other electrical items for correct
operation.
