WARNING!
work for which you have the knowledge
and the proper equipment. If you have any
doubt about your ability to perform a ser-
vice job, take your vehicle to a competent
mechanic.
Windshield Wiper Blades
Clean the rubber edges of the wiper blades
and the windshield periodically with a sponge
or soft cloth and a mild nonabrasive cleaner.
This will remove accumulations of salt or road
film.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using
the wipers to remove salt or dirt from a dry
windshield.
Avoid using the wiper blades to remove frost
or ice from the windshield. Keep the blade
rubber out of contact with petroleum prod-
ucts such as engine oil, gasoline, etc.NOTE:
Life expectancy of wiper blades varies de-
pending on geographical area and frequency
of use. Poor performance of blades may be
present with chattering, marks, water lines or
wet spots. If any of these conditions are
present, clean the wiper blades or replace as
necessary.
The wiper blades and wiper arms should be
inspected periodically, not just when wiper
performance problems are experienced. This
inspection should include the following
points:
• Wear or uneven edges
• Foreign material
• Hardening or cracking
• Deformation or fatigue
If a wiper blade or wiper arm is damaged,
replace the affected wiper arm or blade with
a new unit. Do not attempt to repair a wiper
arm or blade that is damaged.
Wiper Blade Removal/Installation
CAUTION!
Do not allow the wiper arm to spring back
against the glass without the wiper blade
in place or the glass may be damaged.
1. Lift the wiper arm to raise the wiper blade
off of the glass, until the wiper arm is in
the full up position.

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 cylin-
der 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 sys-
tem for leaks.
Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for further information.
WARNING!
• Brake fluid is poisonous and highly cor-
rosive. In the event of accidental con-
tact, immediately wash the affected
parts with water and neutral soap. Then
rinse thoroughly. Call a doctor immedi-
ately if swallowed.
• Use only manufacturer's recommended
brake fluid. Refer to “Fluids And Lubri-
cants” in “Technical Specifications” for
further information. Using the wrong
type of brake fluid can severely damage
WARNING!
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
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
WARNING!
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. An authorized dealer
can check your transmission fluid level using
special service tools. If you notice fluid leak-
age or transmission malfunction, visit an au-
thorized 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 an
authorized dealer immediately. Severe
transmission damage may occur. An au-

Tire Inflation Pressures
The proper cold tire inflation pressure is
listed on the left side B-Pillar or rear edge of
the passenger door.
This placard tells you important information
about the:
1. Number of people that can be carried in
the vehicle.
2. Tire size designed for your vehicle.
3. Cold tire inflation pressures for the front,
rear, and spare tires.At least once a month:
• Check and adjust tire pressure with a good
quality pocket-type pressure gauge. Do not
make a visual judgement when determining
proper inflation. Tires may look properly
inflated even when they are under-inflated.
• Inspect tires for signs of tire wear or visible
damage.
CAUTION!
After inspecting or adjusting the tire pres-
sure, always reinstall the valve stem cap.
This will prevent moisture and dirt from
entering the valve stem, which could dam-
age the valve stem.
Inflation pressures specified on the placard
are always “cold tire inflation pressure”. Cold
tire inflation pressure is defined as the tire
pressure after the vehicle has not been driven
for at least three hours, or driven less than
1 mile (1.6 km) after sitting for a minimum of
three hours. The cold tire inflation pressure
must not exceed the maximum inflation pres-
sure molded into the tire sidewall.Check tire pressures more often if subject to
a wide range of outdoor temperatures, as tire
pressures vary with temperature changes.
Tire pressures change by approximately 1 psi
(7 kPa) per 12°F (7°C) of air temperature
change. Keep this in mind when checking tire
pressure inside a garage, especially in the
Winter.
Example: If garage temperature = 68°F
(20°C) and the outside temperature = 32°F
(0°C) then the cold tire inflation pressure
should be increased by 3 psi (21 kPa), which
equals 1 psi (7 kPa) for every 12°F (7°C) for
this outside temperature condition.
Tire pressure may increase from 2 to 6 psi
(13 to 40 kPa) during operation. DO NOT
reduce this normal pressure build up or your
tire pressure will be too low.
Tire Pressures For High Speed Operation
The manufacturer advocates driving at safe
speeds and within posted speed limits.
Where speed limits or conditions are such
that the vehicle can be driven at high speeds,
maintaining correct tire inflation pressure is
very important. Increased tire pressure and

your tire. The Load Index and Speed Symbol
for your tire will be found on the original
equipment tire sidewall.
It is recommended to replace the two front
tires or two rear tires as a pair. Replacing just
one tire can seriously affect your vehicle’s
handling. If you ever replace a wheel, make
sure that the wheel’s specifications match
those of the original wheels.
It is recommended you contact an authorized
tire dealer or original equipment dealer with
any questions you may have on tire specifi-
cations or capability. Failure to use equiva-
lent replacement tires may adversely affect
the safety, handling, and ride of your vehicle.
WARNING!
• Do not use a tire, wheel size, load rating,
or speed rating other than that specified
for your vehicle. Some combinations of
unapproved tires and wheels may
change suspension dimensions and per-
formance characteristics, resulting in
changes to steering, handling, and brak-
ing of your vehicle. This can cause un-
WARNING!
predictable handling and stress to steer-
ing and suspension components. You
could lose control and have a collision
resulting in serious injury or death. Use
only the tire and wheel sizes with load
ratings approved for your vehicle.
• Never use a tire with a smaller load index
or capacity, other than what was origi-
nally equipped on your vehicle. Using a
tire with a smaller load index could re-
sult in tire overloading and failure. You
could lose control and have a collision.
• Failure to equip your vehicle with tires
having adequate speed capability can
result in sudden tire failure and loss of
vehicle control.
CAUTION!
Replacing original tires with tires of a
different size may result in false speedom-
eter and odometer readings.
Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all sea-
sons (Spring, Summer, Fall, and Winter).
Traction levels may vary between different all
season tires. All season tires can be identi-
fied by the M+S, M&S, M/S or MS designa-
tion on the tire sidewall. Use all season tires
only in sets of four; failure to do so may
adversely affect the safety and handling of
your vehicle.
Summer Or Three Season Tires — If
Equipped
Summer tires provide traction in both wet
and dry conditions, and are not intended to
be driven in snow or on ice. If your vehicle is
equipped with Summer tires, be aware these
tires are not designed for Winter or cold
driving conditions. Install Winter tires on your
vehicle when ambient temperatures are less
than 40°F (5°C) or if roads are covered with
ice or snow. For more information, contact an
authorized dealer.
Summer tires do not contain the all season
designation or mountain/snowflake symbol
SERVICING AND MAINTENANCE

CAUTION!
Proper operation of four-wheel drive ve-
hicles depends on tires of equal size, type
and circumference on each wheel. Any
difference in tire size can cause damage to
the transfer case. Tire rotation schedule
should be followed to balance tire wear.
STORING THE VEHICLE
If you are storing your vehicle for more than
21 days, we recommend that you take the
following steps to minimize the drain on your
vehicle's battery:
• Disconnect the negative cable from battery.
• Any time you store your vehicle or keep it
out of service (i.e., vacation) for two weeksor more, run the air conditioning system at
idle for about five minutes in the fresh air
and high blower setting. This will ensure
adequate system lubrication to minimize
the possibility of compressor damage when
the system is started again.
BODYWORK
Body And Underbody Maintenance
Cleaning Headlights
Your vehicle is equipped with plastic head-
lights and fog lights that are lighter and less
susceptible to stone breakage than glass
headlights.
Plastic is not as scratch resistant as glass and
therefore different lens cleaning procedures
must be followed.
To minimize the possibility of scratching the
lenses and reducing light output, avoid wip-
ing with a dry cloth. To remove road dirt, wash
with a mild soap solution followed by rinsing.
Do not use abrasive cleaning components,
solvents, steel wool or other aggressive mate-
rial to clean the lenses.
Preserving The Bodywork
Washing
• Wash your vehicle regularly. Always wash
your vehicle in the shade using a mild car
wash soap, and rinse the panels completely
with clear water.
• If insects, tar, or other similar deposits have
accumulated on your vehicle, use a specific
detergent to remove.
• Use a high quality cleaner wax to remove
road film, stains and to protect your paint
finish. Take care never to scratch the paint.
• Avoid using abrasive compounds and power
buffing that may diminish the gloss or thin
out the paint finish.
CAUTION!
• Do not use abrasive or strong cleaning
materials such as steel wool or scouring
powder that will scratch metal and
painted surfaces.

CAUTION!
• Use of power washers exceeding
1,200 psi (8,274 kPa) can result in
damage or removal of paint and decals.
Some parts of the vehicle may be painted
with a matte paintwork which requires spe-
cial care for its preservation
CAUTION!
Avoid washing with rollers and/or brushes
in washing stations. Wash the vehicle only
by hand using neutral pH detergents; dry it
with a wet chamois leather. Abrasive prod-
ucts and/or polishes should not be used for
cleaning the car. Bird droppings must be
washed off immediately and thoroughly as
the acid they contain is particularly ag-
gressive. Avoid (if at all possible) parking
the vehicle under trees; remove vegetable
resins immediately as, when dried, it may
only be possible to remove them with abra-
sive products and/or polishes, which is
highly inadvisable as they could alter the
typical opaqueness of the paint. Do not
use pure windshield washer fluid for
CAUTION!
cleaning the front windshield and rear win-
dow; dilute it min. 50% with water. Only
use pure windshield washer fluid when
strictly necessary due to outside tempera-
ture conditions.
Special Care
• If you drive on salted or dusty roads or if you
drive near the ocean, hose off the undercar-
riage at least once a month.
• It is important that the drain holes in the
lower edges of the doors, rocker panels, and
trunk be kept clear and open.
• If you detect any stone chips or scratches in
the paint, touch them up immediately. The
cost of such repairs is considered the re-
sponsibility of the owner.
• If your vehicle is damaged due to a collision
or similar cause that destroys the paint and
protective coating, have your vehicle re-
paired as soon as possible. The cost of such
repairs is considered the responsibility of
the owner.• If you carry special cargo such as chemi-
cals, fertilizers, de-icer salt, etc., be sure
that such materials are well packaged and
sealed.
• If a lot of driving is done on gravel roads,
consider mud or stone shields behind each
wheel.
• Touch up the scratches as soon as possible.
An authorized dealer has touch up paint to
match the color of your vehicle.
Appearance Care For Fabric Top Models
To maintain the appearance of your vehicle's
interior trim and top, follow these precau-
tions:
• Avoid leaving your vehicle unattended with
the top down, as exposure to sun or rain
may damage interior trim.
• Do not use harsh cleaners or bleaching
agents on top material, as damage may
result.
• Do not allow any vinyl cleaner to run down
and dry on the paint, leaving a streak.

Plastic And Coated Parts
Use a specific product to clean vinyl
upholstery.
CAUTION!
• Direct contact of air fresheners, insect
repellents, suntan lotions, or hand sani-
tizers to the plastic, painted, or deco-
rated surfaces of the interior may cause
permanent damage. Wipe away immedi-
ately.
• Damage caused by these type of prod-
ucts may not be covered by your New
Vehicle Limited Warranty.
Cleaning Plastic Instrument Cluster Lenses
The lenses in front of the instruments in this
vehicle are molded in clear plastic. When
cleaning the lenses, care must be taken to
avoid scratching the plastic.1. Clean with a wet soft cloth. A mild soap
solution may be used, but do not use high
alcohol content or abrasive cleaners. If
soap is used, wipe clean with a clean
damp cloth.
2. Dry with a soft cloth.
Leather Parts
Your leather upholstery can be best preserved
by regular cleaning with a damp soft cloth.
Small particles of dirt can act as an abrasive
and damage the leather upholstery and
should be removed promptly with a damp
cloth. Care should be taken to avoid soaking
your leather upholstery with any liquid.
Please do not use polishes, oils, cleaning
fluids, solvents, detergents, or ammonia-
based cleaners to clean your leather uphol-
stery. Application of a leather conditioner is
not required to maintain the original condi-
tion.
NOTE:
If equipped with light colored leather, it tends
to show any foreign material, dirt, and fabric
dye transfer more so than darker colors. The
leather is designed for easy cleaning.
CAUTION!
Do not use Alcohol and Alcohol-based
and/or Ketone based cleaning products to
clean leather seats, as damage to the seat
may result.
Glass Surfaces
All glass surfaces should be cleaned on a
regular basis with any commercial
household-type glass cleaner. Never use an
abrasive type cleaner. Use caution when
cleaning the inside rear window equipped
with electric defrosters or windows equipped
with radio antennas. Do not use scrapers or
other sharp instruments that may scratch the
elements.
When cleaning the rear view mirror, spray
cleaner on the towel or cloth that you are
using. Do not spray cleaner directly on the
mirror.
