CAUTION!
pension components, it is important
that only traction devices in good condi-
tion are used. Broken devices can cause
serious damage. Stop the vehicle imme-
diately if noise occurs that could indi-
cate device breakage. Remove the dam-
aged parts of the device before further
use.
• Install device as tightly as possible and
then retighten after driving about ½ mile
(0.8 km).
• Do not exceed 30 mph (48 km/h).
• Drive cautiously and avoid severe turns
and large bumps, especially with a
loaded vehicle.
• Do not drive for a prolonged period on
dry pavement.
• Observe the traction device manufactur-
er’s instructions on the method of instal-
lation, operating speed, and conditions
for use. Always use the suggested oper-
ating speed of the device manufacturer’s
if it is less than 30 mph (48 km/h).
• Do not use traction devices on a com-
pact spare tire.
Tire Rotation Recommendations
The tires on the front and rear of your vehicle
operate at different loads and perform differ-
ent steering, handling, and braking func-
tions. For these reasons, they wear at unequal
rates.
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. The reasons
for any rapid or unusual wear should be
corrected prior to rotation being performed.
The suggested rotation method is the
“rearward-cross” shown in the following
diagram.
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 weeks

or 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.
• Use a high quality cleaner wax 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.
• Use of power washers exceeding
1,200 psi (8,274 kPa) can result in
damage or removal of paint and decals.
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.

CAUTION!
immediately and thoroughly as the acid
they contain is particularly aggressive.
• 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 abrasive 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 cleaning the front windshield and
rear window; dilute it min. 50% with
water. Only use pure windshield washer
fluid when strictly necessary due to out-
side temperature conditions.
Care Of Fabric Top Windows
Your vehicle's fabric top has pliable plastic
windows which can be scratched unless spe-
cial care is taken by following these directions:
1. Never use a dry cloth to remove dust.
Instead,use a microfiber towel or soft cot-
ton cloth moistened with cold or warm,clean water, and wipe across the window,
not up and down.
2. When washing,never use hot wateror any-
thing stronger than a mild soap. Never use
solvents such as alcohol or harsh cleaning
agents.
3. Always rinse thoroughly with cold water,
then wipe with a soft and slightly moist,
clean cloth.
4. When removing frost, snow or ice,never
use a scraper or de-icing chemicals.Use
warm water only if you must clean the
window quickly.
5. Debris (sand, mud/dirt, dust, or salt) from
off-road driving will have a major impact
on zipper operation. Even normal on-road
driving and vehicle washing will eventu-
ally impact window zipper operation. To
maintain ease of use of the window zip-
pers, each window zipper should be
cleaned and lubricated regularly. Before
applying, make sure the zipper teeth are
clear of sand, mud, and other materials.
Clean both sides of the zipper, not justone side. Rinse both zipper halves with
fresh water and allow to dry. Several ap-
plications may be required before the zip-
per comes free.
6. Never paste stickers, gummed labels or
any tape to the windows. Adhesives are
hard to remove and may damage the
windows.
INTERIORS
Seats And Fabric Parts
WARNING!
Do not use volatile solvents for cleaning
purposes. Many are potentially flam-
mable, and if used in closed areas they
may cause respiratory harm.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with
chemical solvents or abrasive cleaners. This
will weaken the fabric. Sun damage can also
weaken the fabric.

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.
