Installing The Rear Wiper
1. Lift the rear wiper arm pivot cap away from the glass toallow the rear wiper blade to be raised off of the glass.
NOTE: The rear wiper arm cannot be fully raised off the
glass unless the wiper arm pivot cap is unsnapped first.
Attempting to fully raise the rear wiper arm without
unsnapping the wiper arm pivot cap may damage the
vehicle.
2. Lift the rear wiper arm fully off the glass.
3. Insert the wiper blade pivot pin into the opening on the end of the wiper arm. Grab the bottom end of the wiper
arm with one hand, and press the wiper blade flush
with the wiper arm until it snaps into place.
4. Lower the wiper blade onto the glass and snap the wiper arm pivot cap back into place.
Exhaust System
The best protection against carbon monoxide entry into the
vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if the exhaust fumes can be detected inside the vehicle;
or when the underside or rear of the vehicle is damaged; have an authorized technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep into
the passenger compartment. In addition, have the exhaust
system inspected each time the vehicle is raised for lubri-
cation or oil change. Replace as required.
WARNING!
•
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, refer
to “Safety Tips” in “Safety” for further information.
• A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.

CAUTION!
•The catalytic converter requires the use of unleaded
fuel only. Leaded gasoline will destroy the effective-
ness of the catalyst as an emissions control device
and may seriously reduce engine performance and
cause serious damage to the engine.
• Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In
the event of engine malfunction, particularly involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.
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 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!
•Turn vehicle OFF and disconnect the fan motor lead
before working near the radiator cooling fan.
• 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.
• Do not put your hands, tools, clothing, and jewelry
near the radiator cooling fan. The fan may start at any
time, whether the ignition is on or off. This vehicle is equipped with an electric cooling fan
mounted behind the radiator that starts automatically, and
may start at any time. Your vehicle may determine the fan
needs to start and to run if vehicle coolant is too hot, if the
ambient air temperature is too high, or if the vehicle is
charging and the hood is open. Even after the vehicle is
turned off, the fan may start without warning and run for
several minutes. Be aware of this if you are working in the
engine compartment. Always keep fingers and tools away
from the fan blades.
The radiator fan and surrounding components must be
serviced by your authorized dealer.

Engine Coolant Checks
Check the 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 for any accumula-
tion of bugs, leaves, etc. If dirty, clean by gently spraying
water from a garden hose vertically down the face of the
condenser.
Check the engine cooling system hoses for brittle rubber,
cracking, tears, cuts, and tightness of the connection at the
coolant recovery 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 an local authorized
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 Plan” in this section for the
proper maintenance intervals.
Electric/Battery Coolant System
These coolant systems must be serviced by an authorized
dealer. If the coolant level is below what is specified on the
reservoir, contact an authorized dealer for service.
These systems require the use of high purity water, such as
deionized, or distilled water, when mixing the water and
coolant (antifreeze) solution. The use of lower quality
water will reduce the amount of corrosion protection in the
cooling systems. If the coolant level of the battery coolant
system is low, the wrench warning light will be illuminated
on the instrument cluster.
Selection Of Coolant
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.
454 SERVICING AND MAINTENANCE

NOTE:
•Mixing of engine coolant (antifreeze) other than speci-
fied Organic Additive Technology (OAT) engine coolant
(antifreeze), may result in engine damage and may
decrease corrosion protection. Organic Additive Tech-
nology (OAT) engine coolant is different and should not
be mixed with Hybrid Organic Additive Technology
(HOAT) engine coolant (antifreeze) or any “globally
compatible” coolant (antifreeze). 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 possible.
• Do not use water alone or alcohol-based engine coolant
(antifreeze) products. Do not use additional rust inhibi-
tors or antirust products, as they may not be compatible
with the radiator engine coolant and may plug the
radiator.
• This vehicle has not been designed for use with propyl-
ene glycol-based engine coolant (antifreeze). Use of
propylene glycolbased engine coolant (antifreeze) is not
recommended. •
Some vehicles require special tools to add coolant prop-
erly. 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
authorized dealer.
Adding Coolant
Your vehicle has been built with an improved coolant (OAT
coolant conforming to MS.90032) that allows extended
maintenance intervals. This coolant (antifreeze) can be
used up to ten years or 150,000 miles (240,000 km) before
replacement. To prevent reducing this extended mainte-
nance period, it is important that you use the same coolant
(OAT coolant conforming to MS.90032) throughout the life
of your vehicle.
Please review these recommendations for using Organic
Additive Technology (OAT) coolant (antifreeze) that meets
the requirements of FCA Material Standard MS.90032.
When adding coolant (antifreeze):
• We recommend using Mopar Antifreeze/Coolant
10 Year/150,000 Mile (240,000 km) Formula OAT (Or-
ganic Additive Technology) that meets the requirements
of FCA Material Standard MS.90032.

SERVICING AND MAINTENANCE 455

•Mix a minimum solution of 50% OAT coolant that meets
the requirements of FCA Material Standard MS.90032
and deionized, or distilled water. Use higher concentra-
tions (not to exceed 70%) if temperatures below 34°F
(37°C) are anticipated.
CAUTION!
Use only high purity water such as deionized, or
distilled water when mixing the water/ coolant (anti-
freeze) solution for the engine, battery or high voltage
electronics cooling systems. The use of lower quality
water will reduce the amount of corrosion protection in
the engine cooling system.
Please note that it is the owner’s responsibility to maintain
the proper level of protection against freezing according to
the temperatures occurring in the area where the vehicle is
operated. NOTE:
•
Mixing coolant (antifreeze) types is not recommended
and can result in cooling system damage. If HOAT and
OAT coolant are mixed in an emergency, have a autho-
rized dealer drain, flush, and refill with OAT coolant
(conforming to MS.90032) as soon as possible.
• Low pressure expansion bottles for power electronics
and battery cooling require a special tool for removing
the cap from the expansion bottle. For the battery
coolant bottle, it is important to not add coolant if level
is low. The vehicle should be taken to dealer for proper
servicing of the battery coolant loop if this should occur.
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
expansion 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.
456 SERVICING AND MAINTENANCE

WARNING!
•Do not open hot engine cooling system. Never add
engine coolant (antifreeze) when the engine is over-
heated. Do not loosen or remove the cap to cool an
overheated engine. Heat causes pressure 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 Coolant
Used ethylene glycol-based coolant (antifreeze) is a regu-
lated 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 coolant in open contain-
ers 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 expansion bottle provides a quick visual
method for determining that the coolant level is adequate.
With the engine off and cold, the level of the coolant
(antifreeze) in the bottle should be between the “MAX” and
“MIN” lines marked on the bottle.
As long as the engine operating temperature is satisfactory,
the coolant bottle need only be checked once a month.
When additional coolant (antifreeze) is needed to maintain
the proper level, it should be added to the coolant bottle.
Do not overfill.
See an authorized dealer for service.
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.

SERVICING AND MAINTENANCE 457

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 coolant (antifreeze) concentration at a mini-
mum of 50% OAT coolant (conforming to MS.90032) and
deionized, or distilled water.
• Use only high purity water such as deionized, or dis-
tilled water when mixing the water/coolant (antifreeze)
solution for the engine, battery or high voltage electron-
ics cooling systems. The use of lower quality water will
reduce the amount of corrosion protection in the cooling
system.
• 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.
• The coolant freeze point in the battery and power
electronics loop should be checked by a dealer as a
special tool is required to remove the cap from those
expansion bottles.
• Electric/Battery coolant system must be serviced by an
authorized dealer. If the coolant level is below what is
specified on the reservoir, contact an authorized dealer
for service. These systems require the use of high purity
water such as deionized, or distilled water when mixing
the water and coolant (antifreeze) solution. The use of
lower quality water will reduce the amount of corrosion
protection in the cooling systems.
