Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning andcaution statements that appear on thelabel.
Finish maintenance
Washing
To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughlyand frequently at least once a month with
lukewarm or cold water.
If you use your vehicle for off-road driv-
ing, you should wash it after each off-
road trip. Pay special attention to the
removal of any accumulation of salt, dirt,
mud, and other foreign materials. Make
sure the drain holes in the lower edges of
the doors and rocker panels are keptclear and clean.
Insects, tar, tree sap, bird droppings,
industrial pollution and similar deposits
can damage your vehicle’s finish if not
removed immediately.
Even prompt washing with plain water
may not completely remove all these
deposits. A mild soap, safe for use on
painted surfaces, may be used.
After washing, rinse the vehicle thor-
oughly with lukewarm or cold water. Do
not allow soap to dry on the finish.
APPEARANCE CARECAUTION
Do not use strong soap, chemical
detergents or hot water, and do
not wash the vehicle in direct sunlight or when the body of thevehicle is warm.
Be careful when washing the side windows of your vehicle.Especially, with high-pressurewater, water may leak through the windows and wet the interior.
To prevent damage to the plastic parts, do not clean with chemicalsolvents or strong detergents.
WARNING - Wet brakes
After washing the vehicle, test the
brakes whilst driving slowly to see
if they have been affected by water.
If braking performance is impaired,
dry the brakes by applying them
lightly whilst maintaining a slow
forward speed.

Maintenance
Waxing
Wax the vehicle when water will no longer bead on the paint.
Always wash and dry the vehicle before
waxing. Use a good quality liquid or
paste wax, and follow the manufacturer’s
instructions. Wax all metal trim to protect
it and to maintain its luster.
Removing oil, tar, and similar materials
with a spot remover will usually strip the
wax from the finish. Be sure to re-wax
these areas even if the rest of the vehicle
does not yet need waxing.Finish damage repair
Deep scratches or stone chips in the
painted surface must be repaired
promptly. Exposed metal will quickly rust
and may develop into a major repair
expense.
✽✽NOTICE
If your vehicle is damaged and requires
any metal repair or replacement, be sure
the body shop applies anti-corrosion
materials to the parts repaired or
replaced.
CAUTION
Wiping dust or dirt off the body with a dry cloth will scratch the
finish.
Do not use steel wool, abrasive cleaners, or strong detergentscontaining highly alkaline orcaustic agents on chrome-plated
or anodized aluminum parts. Thismay result in damage to the pro-tective coating and cause discol-oration or paint deterioration.
CAUTION
Water washing in the engine com-
partment including high pressurewater washing may cause the fail- ure of electrical circuits or engineand related part located in the
engine compartment.
Never allow water or other liquids to come in contact with electri-cal/electronic components and
air duct inside the vehicle as thismay damage them.

Bright-metal maintenance
To remove road tar and insects, use a
tar remover, not a scraper or other
sharp object.
To protect the surfaces of bright-metal parts from corrosion, apply a coating of
wax or chrome preservative and rub to
a high luster.
During winter weather or in coastal areas, cover the bright metal parts with
a heavier coating of wax or preserva-
tive. If necessary, coat the parts with
non-corrosive petroleum jelly or other
protective compound.
Underbody maintenance
Corrosive materials used for ice and
snow removal and dust control may col-
lect on the underbody. If these materials
are not removed, accelerated rusting can
occur on underbody parts such as the
fuel lines, frame, floor pan and exhaust
system, even though they have been
treated with rust protection.
Thoroughly flush the vehicle underbody
and wheel openings with lukewarm or
cold water once a month, after off-road
driving and at the end of each winter. Payspecial attention to these areas because
it is difficult to see all the mud and dirt. It
will do more harm than good to wet down
the road grime without removing it. The
lower edges of doors, rocker panels, and
frame members have drain holes that
should not be allowed to clog with dirt;
trapped water in these areas can cause
rusting.WARNING
After washing the vehicle, test the
brakes whilst driving slowly to see
if they have been affected by water.
If braking performance is impaired,
dry the brakes by applying them
lightly whilst maintaining a slow
forward speed.

Maintenance
Aluminum wheel maintenance
The aluminum wheels are coated with a
clear protective finish.
Do not use any abrasive cleaner, pol-ishing compound, solvent, or wire
brushes on aluminum wheels. They
may scratch or damage the finish.
Use only a mild soap or neutral deter- gent, and rinse thoroughly with water.
Also, be sure to clean the wheels after
driving on salted roads. This helps pre-
vent corrosion.
Avoid washing the wheels with high- speed car wash brushes.
Do not use any acid detergent. It may damage and corrode the aluminum
wheels coated with a clear protectivefinish.
Corrosion protection
Protecting your vehicle from corrosion
By using the most advanced design and
construction practices to combat corro-
sion, we produces cars of the highest
quality. However, this is only part of the
job. To achieve the long-term corrosion
resistance your vehicle can deliver, the
owner's cooperation and assistance isalso required.
Common causes of corrosion The most common causes of corrosion
on your car are:
allowed to accumulate underneath the
car.
Removal of paint or protective coatings by stones, gravel, abrasion or minor
scrapes and dents which leave unpro-
tected metal exposed to corrosion. High-corrosion areas
If you live in an area where your car is
regularly exposed to corrosive materials,
corrosion protection is particularly impor-
tant. Some of the common causes of
accelerated corrosion are road salts,
dust control chemicals, ocean air and
industrial pollution.
Moisture breeds corrosion Moisture creates the conditions in which
corrosion is most likely to occur. For
example, corrosion is accelerated by
high humidity, particularly when tempera-
tures are just above freezing. In such
conditions, the corrosive material is kept
in contact with the car surfaces by mois-
ture that is slow to evaporate.
Mud is particularly corrosive because it is
slow to dry and holds moisture in contact
with the vehicle. Although the mud
appears to be dry, it can still retain themoisture and promote corrosion.
High temperatures can also accelerate
corrosion of parts that are not properly
ventilated so the moisture can be dis-
persed. For all these reasons, it is par-
ticularly important to keep your car clean
and free of mud or accumulations of
other materials. This applies not only to
the visible surfaces but particularly to the
underside of the car.
