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 a local 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.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
engine coolant, and to ensure that engine coolant
will return to the radiator from the coolant recovery
tank.
The cap should be inspected and cleaned if there
is any accumulation of foreign material on the
sealing surfaces.
The image on the coolant system
pressure cap is a reminder that the
radiator contains hot engine coolant
under pressure.Disposal Of Used Coolant
Used ethylene glycol-based coolant is a regulated
substance requiring proper disposal. Check with
your local authorities to determine the disposal
rules for your community. To prevent ingestion, do
not store ethylene glycol-based coolant in open
containers or allow it to remain in puddles on the
ground, clean up immediately. If ingested, seek
emergency assistance 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 engine coolant in the bottle should
be between the “MIN” and “MAX” marks.
The radiator normally remains completely full, so
there is no need to remove the radiator/coolant
pressure cap unless checking for engine coolant
freeze point or replacing coolant. Advise an
authorized dealer of this. As long as the engine
operating temperature is satisfactory, the coolant
only needs to be checked once a month.
When additional engine coolant is needed to
maintain the proper level, only OAT coolant that
meets the requirements of the manufacturer
Material Standard MS.90032 should be added to
the coolant bottle. Do not overfill.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.

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 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.
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 190.
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 the manufacturer
recommended brake fluid Ú page 241.
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 the manufacturer recommended
brake fluid Úpage 241. 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.

CAUTION!
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 Technology (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 authorized dealer as soon as possible.
Do not use water alone or alcohol-based engine coolant products. Do not use additional rust inhibitors 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 propylene glycol-based engine coolant. Use of propylene glycol-based engine coolant is not recommended.
Component Fluid, Lubricant, or Genuine Part
Automatic Transmission Use only Mopar® ZF 8 & 9 Speed ATF Automatic Transmission Fluid, or
equivalent.
Failure to use the correct fluid may affect the function or performance of your
transmission.
Brake Master Cylinder We recommend using Mopar® DOT 4.
The fluid must be changed every 24 months. This interval is time based only,
mileage intervals do not apply.
Power Steering Reservoir Use Pentosin CHF 11S power steering fluid meeting the manufacturer
Material Standard MS-11655.
