voir, take some washer fluid and apply it to a
cloth or towel and wipe clean the wiper
blades, this will help blade performance. To
prevent freeze-up of your windshield washer
system in cold weather, select a solution or
mixture that meets or exceeds the tempera-
ture range of your climate. This rating infor-
mation can be found on most washer fluid
containers.
WARNING!
Commercially available windshield washer
solvents are flammable. They could ignite
and burn you. Care must be exercised
when filling or working around the washer
solution.
Brake System
In order to assure brake system performance,
all brake system components should be in-
spected periodically. Refer to the “Mainte-
nance Plan” in this section for the proper
maintenance intervals.
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 tem-
peratures, excessive lining wear, and pos-
sible brake damage. You would not have
your full braking capacity in an emergency.
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 to the full mark 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 system for leaks.
Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for further information.
WARNING!
• Use only manufacturer's recommendedbrake fluid. Refer to “Fluids And Lubri-
cants” in “Technical Specifications” for
further information. Using the wrong
type of brake fluid can severely damage
your brake system and/or impair its per-
formance. The proper type of brake fluid
for your vehicle is also identified on the
original factory installed hydraulic mas-
ter 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 cylin-
der 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 fail-
ure. This could result in a collision.
• Overfilling the brake fluid reservoir can
result in spilling brake fluid on hot en-
gine parts, causing the brake fluid to
249

WARNING!
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
contaminate the brake fluid. Brake seal
components could be damaged, causing
partial or complete brake failure. This
could result in a collision.
Automatic Transmission
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 trans-
mission has no dipstick. Your authorized
dealer can check your transmission fluid
level using special service tools. If you notice
fluid leakage or transmission malfunction,
visit your authorized dealer immediately to
have the transmission fluid level checked.
Operating the vehicle with an improper fluid
level can cause severe transmission damage.
CAUTION!
If a transmission fluid leak occurs, visit
your authorized dealer immediately. Se-
vere transmission damage may occur. Your
authorized dealer has the proper tools to
adjust the fluid level accurately.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-
free battery. You will never have to add water,
nor is periodic maintenance required.
WARNING!
• Battery fluid is a corrosive acid solutionand can burn or even blind you. Do not
allow battery fluid to contact your eyes,
skin, or clothing. Do not lean over a
battery when attaching clamps. If acid
splashes in eyes or on skin, flush the
area immediately with large amounts of
water. Refer to “Jump-Starting” in “In
Case Of Emergency” for further informa-
tion.
WARNING!
• Battery gas is flammable and explosive.Keep flame or sparks away from the
battery. Do not use a booster battery or
any other booster source with an output
greater than 12 Volts. Do not allow cable
clamps to touch each other.
• Battery posts, terminals, and related ac-
cessories contain lead and lead com-
pounds. Wash hands after handling.
CAUTION!
• It is essential when replacing the cableson the battery that the positive cable is
attached to the positive post and the
negative cable is attached to the nega-
tive post. Battery posts are marked posi-
tive (+) and negative (-) and are identi-
fied on the battery case. Cable clamps
should be tight on the terminal posts
and free of corrosion.
• If a “fast charger” is used while the
battery is in the vehicle, disconnect both
vehicle battery cables before connecting
the charger to the battery. Do not use a

DEALER SERVICE
Your authorized dealer has the qualified ser-
vice personnel, special tools, and equipment
to perform all service operations in an expert
manner. Service Manuals are available which
include detailed service information for your
vehicle. Refer to these Service Manuals be-
fore attempting any procedure yourself.
NOTE:
Intentional tampering with emissions control
systems may void your warranty and could
result in civil penalties being assessed
against you.
WARNING!
You can be badly injured working on or
around a motor vehicle. Only do service
work for which you have the knowledge
and the proper equipment. If you have any
WARNING!
doubt about your ability to perform a ser-
vice job, take your vehicle to a competent
mechanic.
Air Conditioner Maintenance
For best possible performance, your air con-
ditioner should be checked and serviced by
an authorized dealer at the start of each warm
season. This service should include cleaning
of the condenser fins and a performance test.
Drive belt tension should also be checked at
this time.
WARNING!
• Use only refrigerants and compressorlubricants approved by the manufac-
turer for your air conditioning system.
Some unapproved refrigerants are flam-
mable and can explode, injuring you.
Other unapproved refrigerants or lubri-
cants can cause the system to fail, re-
quiring costly repairs. Refer to Warranty
WARNING!
Information Book, for further warranty
information.
• The air conditioning system contains re-
frigerant under high pressure. To avoid
risk of personal injury or damage to the
system, adding refrigerant or any repair
requiring lines to be disconnected
should be done by an experienced tech-
nician.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components.
Such damage is not covered by the New
Vehicle Limited Warranty.

Tire Safety Information
Tire safety information will cover aspects of
the following information: Tire Markings, Tire
Identification Numbers, Tire Terminology and
Definitions, Tire Pressures and Tire Loading.
Tire Markings
NOTE:
• P (Passenger) — Metric tire sizing isbased on U.S. 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
European design standards. Tires de-
signed to this standard have the tire size
molded into the sidewall 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 U.S. 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 temporary emergency use only. Temporary
high pressure 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 U.S. design standards and it begins with the
tire diameter molded into the sidewall.
Example: 31x10.5 R15 LT.

These effects can be reduced by timely rota-
tion of tires. The benefits of rotation are
especially worthwhile with aggressive tread
designs such as those on On/Off-Road type
tires. Rotation will increase tread life, help to
maintain mud, snow, and wet traction levels,
and contribute to a smooth, quiet ride.
Refer to the “Maintenance Plan” for the
proper maintenance intervals. More frequent
rotation is permissible if desired. The reasons
for any rapid or unusual wear should be
corrected prior to rotation being performed.
NOTE:
The premium Tire Pressure Monitor System
will automatically locate the pressure values
displayed in the correct vehicle position fol-
lowing a tire rotation.
The suggested rotation method is the

TRANSPORTATION
UNIFORM TIRE QUALITY
GRADES
The following tire grading categories were
established by the National Highway Traffic
Safety Administration. The specific grade
rating assigned by the tire's manufacturer in
each category is shown on the sidewall of the
tires on your vehicle.
All passenger vehicle tires must conform to
Federal safety requirements in addition to
these grades.
Treadwear
The Treadwear grade is a comparative rating,
based on the wear rate of the tire when tested
under controlled conditions on a specified
government test course. For example, a tire
graded 150 would wear one and one-half
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and may depart signifi-
cantly from the norm due to variations in
driving habits, service practices, and differ-
ences in road characteristics and climate.
Traction Grades
The Traction grades, from highest to lowest,
are AA, A, B, and C. These grades represent
the tire's ability to stop on wet pavement, as
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete. A tire marked C may have poor
traction performance.
