Fluid Level Check — Brake Master Cylinder
Check the fluid level in the master cylinder
immediately if the brake system warning light
indicates system failure.
Check the fluid level in the master cylinder when
pe

rforming underhood services.
Clean the top of the master cylinder area before
re
moving the cap. Add fluid to bring the level up to
the top of the “FULL” mark on the side of the
master cylinder reservoir.
Overfilling of fluid is not recommended because it
ma
y cause leaking in the system.
Add enough fluid to bring the level up to the
re
quirements described on the brake fluid reservoir. With disc brakes, fluid level can be
expected to fall as the brake pads wear. However,
low fluid level may be caused by a leak and a
checkup may be needed.
Use only brake fluid that has been recommended
b
y

the manufacturer, and has been kept in a tightly
closed container to avoid contamination from
foreign matter or moisture
Ú page 250.
AUTOMATIC TRANSMISSION
Special Additives
The manufacturer strongly recommends 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.
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's recommended brake
fluid Ú page 250. Using the wrong type of
brake fluid can severely damage your brake
s y
stem 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
c ou
ld be damaged, causing partial or
complete brake failure. This could result in a
collision.

SERVICING AND MAINTENANCE 213
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.
How e

ver, 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's specified
transmission fluid
Ú page 250. It is important to
maintain the transmission fluid at the correct level
u s
ing the recommended fluid.
NOTE:
No chemical flushes should be used in any trans -
mission; only the approved lubricant should be
u s

ed.
ALL WHEEL DRIVE (AWD) —
I
F EQUIPPED
The All Wheel Drive system consists of a transfer
case and front differential. The exterior surface of
these components should be inspected for
evidence of fluid leaks. Confirmed leaks should be
repaired as soon as possible.
The transfer case fluid fill/inspection plug is
l oc

ated in the middle of the rear housing. To
inspect the transfer case fluid level, remove the
fill/inspection plug. The fluid level should be even
with the bottom of the hole. Use this plug to add
fluid as required.
The front differential fill plug is located on the outer
cov
er near the half shaft attachment. To inspect
the differential fluid level, remove the fill plug. The
fluid level should be even with or slightly below the
bottom of the hole.
Fluid Changes
For the proper maintenance intervals Ú page 195.
REAR AXLE
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

Ú page 250.
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.
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’s recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder
