

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 a 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 (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 engine coolant (antifreeze) in the bottle

should be between the “MIN” and “MAX” marks.
As long as the engine operating temperature is

satisfactory, the coolant bottle need only be

checked once a month.
When additional engine coolant is needed to

maintain the proper level, it should be added to the

coolant bottle. Do not overfill.

Cooling System Notes

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 (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.

WARNING!



Do not open 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 MAINTENANCE

(Continued)



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.

In order to ensure brake system performance, all

brake system components should be inspected

periodically. For the proper maintenance intervals

Ú

page 268.

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 324.

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

Ú

page 324. 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 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

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.

Special Additives

It is strongly recommended against using any

special additives in the transmission. Automatic

Transmission Fluid (ATF) is an engineered product

and its performance may be impaired by

supplemental additives. Therefore, do not add any

fluid additives to the transmission. The only

exception to this policy is the use of special dyes

for diagnosing fluid leaks in 6-speed

transmissions. Avoid using transmission sealers as

they may adversely affect seals.

Fluid Level Check

The fluid level is preset at the factory and does not

require adjustment under normal operating

conditions. Routine fluid level checks are not

required; therefore the transmission has no

dipstick. An authorized dealer can check your

transmission fluid level using special service tools.

If you notice fluid leakage or transmission

malfunction, visit an authorized dealer

immediately to have the transmission fluid level

checked. Operating the vehicle with an improper

fluid level can cause severe transmission damage.

Fluid And Filter Changes

Under normal operating conditions, the fluid

installed at the factory will provide satisfactory

lubrication for the life of the vehicle.
Routine fluid and filter changes are not required.

However, change the fluid and filter if the fluid

becomes contaminated (with water, etc.), or if the

transmission is disassembled for any reason.

Selection Of Lubricant

It is important to use the proper transmission fluid

to ensure optimum transmission performance and

life. Use only the manufacturer specified

transmission fluid

Ú

page 324. It is important to

maintain the transmission fluid at the correct level

using the recommended fluid.
NOTE:

No chemical flushes should be used in any trans

-

mission; only the approved lubricant should be

used.



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.

CAUTION!

Do not use chemical flushes in your

transmission as the chemicals can damage your

transmission components. Such damage is not

covered by the New Vehicle Limited Warranty.

WARNING!

CAUTION!

If a transmission fluid leak occurs, visit an

authorized dealer immediately. Severe

transmission damage may occur. An authorized

dealer has the proper tools to adjust the fluid

level accurately.

CAUTION!

Using a transmission fluid other than the

manufacturer recommended fluid may cause

deterioration in transmission shift quality and/or

torque converter shudder. For fluid

specifications
