APPEARANCE CARE
Exterior care
Exterior general caution
It is very important to follow the label
directions when using any chemical
cleaner or polish. Read all warning and
caution statements that appear on the
label.
Finish maintenance
Washing
To help protect your vehicle’s finish from
rust and deterioration, wash it thoroughly
and 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 kept
clear 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.
CAUTION
Do not use strong soap, chemical
detergents or hot water, and do
not wash the vehicle in direct
sunlight or when the body of the
vehicle is warm.
Be careful when washing the side
windows of your vehicle.
Especially, with high-pressure
water, water may leak through the
windows and wet the interior.
To prevent damage to the plastic
parts and lamps, do not clean
with chemical solvents or strong
detergents.
WARNING
Do not wash the engine compart-
ment and trunk with water. The
hybrid system is located in the
engine compartment and trunk. If
water enters the engine or hybrid
battery in the trunk, electric shocks
or burns may result in serious injury
or death.
CAUTION
Water washing in the engine com-
partment including high pressure
water washing may cause the fail-
ure of electrical circuits or engine
and related components located
in the engine compartment.
Never allow water or other liquids
to come in contact with electri-
cal/electronic components and
air ducts inside the vehicle as this
may damage them.

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.
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. Pay
special 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.
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 detergents
containing highly alkaline or
caustic agents on chrome-plated
or anodized aluminum parts. This
may result in damage to the pro-
tective coating and cause discol-
oration or paint deterioration.
