324SERVICING AND MAINTENANCE  
NOTE:Intentional tampering with emissions control 
systems 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 the manufacturer specifications, should 
be obtained immediately.
To minimize the possibility of catalytic converter 
damage:
Do not interrupt the ignition when the transmis -
sion 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 compo -
nents disconnected or removed, such as when 
diagnostic testing, or for prolonged periods 
during very rough idle or malfunctioning oper -
ating conditions.
COOLING SYSTEM
Engine Coolant Checks
Check the engine coolant (antifreeze) protection 
every 12 months (before the onset of freezing 
weather, where applicable). If the engine coolant is 
dirty, the system should be drained, flushed, and 
refilled with fresh Organic Additive Technology 
(OAT) coolant (conforming to MS.90032) by an  authorized dealer. 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.
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 authorized dealer.
If the engine coolant (antifreeze) is dirty or 
contains visible sediment, have an authorized 
dealer clean and flush with Organic Additive 
Technology (OAT) coolant (conforming to 
MS.90032).
For the proper maintenance intervals  
Úpage 310.
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 radi -
ator 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 automatically and may 
start at any time, whether the engine is 
running or not.
When working near the radiator cooling fan, 
disconnect the fan motor lead or turn the igni -
tion to the OFF mode. The fan is temperature 
controlled and can start at any time the igni -
tion is in the ON mode.

Selection Of Coolant 
For further information  Úpage 365.
NOTE:
Mixing of engine coolant (antifreeze) other than 
specified Organic Additive Technology (OAT) 
engine coolant, may result in engine damage 
and may decrease corrosion protection. 
OAT engine coolant is different and should not 
be mixed with Hybrid Organic Additive Tech -
nology (HOAT) engine coolant or any “globally 
compatible” coolant. If a non-OAT engine 
coolant 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 autho -
rized dealer as soon as possible.
Do not use water alone or alcohol-based engine 
coolant products. Do not use additional rust 
inhibitors or anti-rust 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 
propylene glycol-based engine coolant. Use of 
propylene glycol-based engine coolant is not 
recommended.
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 authorized dealer.
Adding Coolant 
Your vehicle has been built with an improved 
engine coolant (OAT coolant conforming to 
MS.90032) that allows extended maintenance 
intervals. This engine coolant (antifreeze) can be 
used up to ten years or 150,000 miles
(240,000 km) before replacement. To prevent 
reducing this extended maintenance period, it is 
important that you use the same engine coolant 
(OAT coolant conforming to MS.90032) throughout 
the life of your vehicle.
Please review these recommendations for using 
OAT engine coolant that meets the requirements of 
the manufacturer Material Standard MS.90032. 
When adding engine coolant:
We recommend using Mopar® Antifreeze/
Coolant 10 Year/150,000 Mile (240,000 km) 
Formula OAT that meets the requirements of the 
manufacturer Material Standard MS.90032.
Mix a minimum solution of 50% OAT engine 
coolant that meets the requirements of the 
manufacturer Material Standard MS.90032 
and distilled water. Use higher concentrations 
(not to exceed 70%) if temperatures 
below −34°F (−37°C) are anticipated. Please 
contact an authorized dealer for assistance.
Use only high purity water such as distilled or 
deionized water when mixing the water/engine 
coolant solution. The use of lower quality water 
will reduce the amount of corrosion protection 
in the engine cooling system.
NOTE:
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.
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 authorized 
dealer.
Mixing engine coolant types is not recom -
mended and can result in cooling system 
damage. If HOAT and OAT coolant are mixed in 
an emergency, have an authorized dealer drain, 
flush, and refill with OAT coolant (conforming to 
MS.90032) as soon as possible.

326SERVICING AND MAINTENANCE  
Cooling System Pressure Cap   
The cap must be fully tightened to prevent loss of 
engine coolant (antifreeze), and to ensure that 
engine coolant will return to the radiator from the 
coolant expansion bottle/recovery tank (if 
equipped).
The cap should be inspected and cleaned if there 
is any accumulation of foreign material on the 
sealing surfaces.
Disposal Of Used Coolant 
Used ethylene glycol-based 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 coolant 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 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 is needed to maintain the 
proper level, it should be added to the coolant 
bottle. Do not overfill.
See an authorized dealer for service.
Cooling System Notes
NOTE:When the vehicle is stopped after a few miles/kilo -
meters 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 (antifreeze) 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 needs to be added, the contents of the 
coolant expansion bottle must also be protected 
against freezing.
If frequent engine coolant additions are 
required, the cooling system should be pressure 
tested for leaks.
Maintain engine coolant concentration at a 
minimum of 50% OAT coolant (conforming to 
MS.90032) and distilled water for proper corro -
sion protection of your engine which contains 
aluminum components.
WARNING!
Do not open a 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 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 
specified for your vehicle. Personal injury or 
engine damage may result.

SERVICING AND MAINTENANCE327
(Continued)
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 neces -
sary, install ONLY the correct type thermostat. 
Other designs may result in unsatisfactory 
engine cooling performance, poor gas mileage, 
and increased emissions.
BRAKE SYSTEM 
In order to ensure brake system performance, all 
brake system components should be inspected 
periodically. For the proper maintenance intervals 
Ú page 310.
Brake Master Cylinder
The fluid in the master cylinder should be checked 
when performing under hood services or 
immediately if the Brake Warning Light is 
illuminated.
Be sure to 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. 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 recommended brake fluid  
Úpage 366.
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 temperatures, excessive 
lining wear, and possible brake damage. You 
would not have your full braking capacity in an 
emergency.
WARNING!
Use only manufacturer recommended brake 
fluid Ú page 366. Using the wrong type of 
brake fluid can severely damage your brake 
system and/or impair its performance. 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 
moisture, use only new brake fluid or fluid that 
has been in a tightly closed container. Keep 
the master cylinder reservoir cap secured at 
all times. Brake fluid in an 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 failure. This 
could result in a collision.
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.
Do not allow petroleum-based fluid to contam -
inate the brake fluid. Brake seal components 
could be damaged, causing partial or 
complete brake failure. This could result in a 
collision.
