In order to ensure brake system performance, all

brake system components should be inspected

periodically. For the proper maintenance intervals

Ú

page 385.

Fluid Level Check — Brake Master Cylinder

The fluid level of the master cylinder should be

checked whenever the vehicle is serviced, or

immediately if the Brake System Warning Light is

on. If necessary, add fluid to bring level within the

designated marks on the side of the reservoir of

the brake master cylinder. Be sure to clean the top

of the master cylinder area before removing cap.

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. If the brake fluid

is abnormally low, check the system for leaks.

LUID

For normal service, periodic fluid level checks are

not required. When the vehicle is serviced for other

reasons the exterior surfaces of the axle assembly

should be inspected. If gear oil leakage is

suspected, inspect the fluid level.

Fluid Level Check

Lubricant should be approximately 1/8 inch

(3 mm) below the bottom edge of the oil fill hole.
NOTE:

Make sure that the vehicle is level and supported

by the axles.

Adding Fluid

Add lubricant only at the fill hole and only to the

level specified above.

Selection Of Lubricant

Use only the manufacturer’s recommended fluid

Ú

page 461.

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 461. 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.



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.

Fluid Level Check

Check the fluid level by removing the fill plug. The

fluid level should be between the bottom of the fill

hole and a point not more than 3/16 of an inch

(4.76 mm) below the bottom of the hole.
Add fluid, if necessary, to maintain the proper

level.

Frequency Of Fluid Change

Under normal operating conditions, the fluid

installed at the factory will give satisfactory

lubrication for the life of the vehicle. If the fluid

becomes contaminated with water, it should be

changed immediately. Otherwise, change the fluid

as recommended in the Maintenance Plan

Ú

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. Avoid using

transmission sealers as they may adversely affect

seals.

2 — Drain Hole

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.

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 manufacturer's specified

transmission fluid

Ú

page 461. 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.

USES

General Information

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

manufacturer’s recommended fluid may cause

deterioration in transmission shift quality and/or

torque converter shudder

Ú

page 461.

WARNING!



When replacing a blown fuse, always use an

appropriate replacement fuse with the same

amp rating as the original fuse. Never replace

a fuse with another fuse of higher amp rating.

The use of a fuse with a rating other than indi

-

cated may result in a dangerous electrical

system overload. If a properly rated fuse

continues to blow, it indicates a problem in the

circuit that must be corrected. Never replace a

blown fuse with metal wires or any other mate

-

rial. Failure to use proper fuses may result in

serious personal injury, fire and/or property

damage.



Before replacing a fuse, make sure that the

ignition is off and that all the other services

are switched off and/or disengaged.



If the replaced fuse blows again, contact an

authorized dealer.



If a general protection fuse for safety systems

(air bag system, braking system), power unit

systems (engine system, gearbox system) or

steering system blows, contact an authorized

dealer.

SERVICING AND MAINTENANCE

The fuses protect electrical systems against

excessive electrical current.
When a device does not work, you must check

the fuse element inside the blade fuse for a

break/melt.
Also, please be aware that when using power

outlets for an extended period of time with the

engine off, it may result in vehicle battery

discharge.

Blade Fuses

Power Distribution Center (PDC)

The Power Distribution Center is located in the

engine compartment near the battery. This center

contains cartridge fuses, mini fuses, and relays.

The PDC top cover is labeled with each serviceable

fuse/relay location, function, and size.

1 — Fuse Element
2 — Blade Fuse with a good/functional fuse

element
3 — Blade fuse with a bad/not functional fuse

element (blown fuse)

CAUTION!



When installing the power distribution center

cover, it is important to ensure the cover is

properly positioned and fully latched. Failure

to do so may allow water to get into the power

distribution center and possibly result in an

electrical system failure.
