grease, such as Mopar® Spray White Lube to ensure

quiet, easy operation and to protect against rust and

wear. Prior to the application of any lubricant, the parts

concerned should be wiped clean to remove dust and

grit; after lubricating, excess oil and grease should be

removed. Particular attention should also be given to

hood latching components to ensure proper function.

When performing other underhood services, the hood

latch release mechanism, and safety catch should be

cleaned and lubricated.

Cooling System — Drain, Flush And Refill

WARNING!

NOTE:

● This vehicle has not been designed for use

with propylene glycol-based motor coolant. Use

of propylene glycol-based motor coolant is not

recommended.

● 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.

Some vehicles require special tools to add coolant

properly. Failure to fill these systems properly could

lead to severe internal traction system damage. If any

coolant is needed to be added to the system please

contact an authorized dealer.

● Some vehicles require special tools to add coolant

properly. Failure to fill these systems properly could

lead to severe internal motor damage. If any coolant

is needed to be added to the system please contact

an authorized dealer.

If the traction system coolant (antifreeze) is dirty or

contains visible sediment, have an authorized dealer

clean and flush with OAT coolant (conforming to

MS.90032).

● 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.

Adding Coolant

For the proper maintenance intervals

page 178.

The vehicle has been built with an improved traction

system coolant (OAT coolant conforming to MS.90032)

that allows extended maintenance intervals. This

traction system coolant (antifreeze) can be used

up to 10 years or 150,000 miles (240,000 km)

before replacement. To prevent reducing this extended

maintenance period, it is important to use the same

traction system coolant (OAT coolant conforming to

MS.90032) throughout the life of your vehicle.

● When working near the radiator cooling fan,

disconnect the fan motor lead and turn the

ignition to the OFF mode. The fan is temperature

controlled and can start at any time the ignition is

in the ON mode.

Selection Of Coolant

For further information

page 206.

NOTE:

● Mixing of motor coolant (antifreeze) other than

specified Organic Additive Technology (OAT) motor

coolant, may result in motor damage and may

decrease corrosion protection. OAT motor coolant

is different and should not be mixed with Hybrid

Organic Additive Technology (HOAT) motor coolant

or any “globally compatible” coolant. If a non-OAT

motor 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.

Coolant Checks

Check the traction system coolant (antifreeze)

protection every 12 months (before the onset of

freezing weather, where applicable). If the traction

system coolant is dirty, the system should be drained,

flushed, and refilled with fresh OAT coolant (conforming

to MS-12106) only 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.

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.

● If any coolant is needed to be added to the system,

please contact an authorized dealer.

● Do not use water alone or alcohol-based motor

coolant products. Do not use additional rust

inhibitors or antirust products, as they may not be

adequate. With engine off and cold, the level of the

motor coolant (antifreeze) in the bottle should be

between the “MIN” and “MAX” marks.

● Make sure that the coolant expansion bottle

overflow hoses are not kinked or obstructed.

The cap should be inspected and cleaned if there is

any accumulation of foreign material on the sealing

surfaces.

● Keep the front of the radiator clean. If your vehicle is

equipped with air conditioning, keep the front of the

condenser clean.

Cooling System Notes

NOTE:

● 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 traction system cooling

performance, poor gas mileage, and increased

emissions.

WARNING!

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 traction system coolant (antifreeze) to enter the

radiator.

● Do not open hot traction cooling system. Never

add traction system coolant (antifreeze) when the

motor is overheated. Do not loosen or remove the

cap to cool an overheated motor. 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.

BRAKE SYSTEM

In order to ensure brake system performance, all brake

system components should be inspected periodically

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.

page 178.

● Do not use a pressure cap other than the one

specified for your vehicle. Personal injury or motor

damage may result.

● Do not overfill the coolant expansion bottle.

WARNING!

● Check the coolant freeze point in the radiator and

in the coolant expansion bottle. If traction system

coolant needs to be added, the contents of the

coolant expansion bottle must also be protected

against freezing.

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.

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.

● If frequent traction system coolant additions are

required, the cooling system should be pressure

tested for leaks.

Fluid Level Check — Brake Master

Cylinder

● Maintain engine coolant concentration at a

minimum of 50% OAT coolant (conforming to

MS.90032) and distilled water for proper corrosion

protection of your traction system which contains

aluminum components.

The fluid level of the master cylinder should be

checked when performing under the hood service

or immediately if the Brake System Warning Light

indicates system failure. If necessary, add fluid to bring

level within the designated marks on the side of the

Coolant Level

The coolant expansion bottle provides a quick visual

method for determining that the coolant level is
