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 Ú page 247.
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
performing underhood services.
Clean the top of the master cylinder area before
removing 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
may cause leaking in the system.
Add enough fluid to bring the 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. However,
low fluid level may be caused by a leak and a
checkup may be needed.
Use only brake fluid that has been recommended
by the manufacturer, and has been kept in a tightly
closed container to avoid contamination from
foreign matter or moisture Ú page 306.
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 Úpage 306. 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.8

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's specified
transmission fluid Ú page 306. 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.
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
located 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
cover 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 Úpage 246.
REAR AXLE
Fluid Level Check
Checking the fluid level while the vehicle is on level
ground and has been stationary for 15 minutes will
improve the accuracy of the fluid level reading. Check the fluid level by removing the fill plug on the
axle. The fluid level should be 1-2.5 mm below the
fill plug. Add fluid, if necessary, to maintain the
proper level Ú
page 306.
Change Axle Fluid
For the proper maintenance intervals Úpage 246.
FUSES
General Information
CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder Ú page 306.
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.
Never replace a blown fuse with metal wires or
any other material. Do not place a fuse inside
a circuit breaker cavity or vice versa. 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.

Rear Interior Fuses
There is also a power distribution center located in
the trunk under the spare tire access panel. This
center contains fuses and relays. Fuse cavity
location and descriptions are printed on the inside
of the power distribution center cover.

Rear Power Distribution Center
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.
When replacing a blown fuse, it is important to
use only a fuse having the correct amperage
rating. The use of a fuse with a rating other
than indicated may result in a dangerous elec-
trical system overload. If a properly rated fuse
continues to blow, it indicates a problem in the
circuit that must be corrected.

Tire Markings

NOTE:
P (Passenger) — Metric tire sizing is based on US
design standards. P-Metric tires have the letter
“P” molded into the sidewall preceding the size
designation. Example: P215/65R15 95H.
European — Metric tire sizing is based on Euro -
pean design standards. Tires designed to this
standard have the tire size molded into the side -
wall beginning with the section width. The letter
"P" is absent from this tire size designation.
Example: 215/65R15 96H.
LT (Light Truck) — Metric tire sizing is based on
US design standards. The size designation for
LT-Metric tires is the same as for P-Metric tires
except for the letters “LT” that are molded into
the sidewall preceding the size designation.
Example: LT235/85R16.
Temporary spare tires are designed for tempo -
rary emergency use only. Temporary high pres -
sure compact spare tires have the letter “T” or
“S” molded into the sidewall preceding the size
designation. Example: T145/80D18 103M.
High flotation tire sizing is based on US design
standards and it begins with the tire diameter
molded into the sidewall. Example: 31x10.5
R15 LT.

H = Speed Symbol
A symbol indicating the range of speeds at which a tire can carry a load corresponding to its load index under certain operating conditions
The maximum speed corresponding to the speed symbol should only be achieved under specified operating conditions (i.e., tire pressure, vehicle loading,
road conditions, and posted speed limits)
Load Identification:
Absence of the following load identification symbols on the sidewall of the tire indicates a Standard Load (SL) tire:
XL = Extra load (or reinforced) tire, or
LL = Light load tire or
C, D, E, F, G = Load range associated with the maximum load a tire can carry at a specified pressure
Maximum Load – Maximum load indicates the maximum load this tire is designed to carry
Maximum Pressure – Maximum pressure indicates the maximum permissible cold tire inflation pressure for this tire
