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
driving, 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, should be
used.
After washing, rinse the vehicle thor-
oughly with lukewarm or cold water.
Do not allow soap to dry on the fin-
ish.
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 inte-
rior.
To prevent damage to the
plastic parts, do not clean
with chemical solvents or
strong detergents.
CAUTION
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water before getting on the
road. If braking performance is
impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.

Maintenance
Aluminum and chrome wheelmaintenance
The aluminum and chrome wheels are
coated with a clear protective finish.
Corrosion protection
Protecting your vehicle from corro-
sion
By using the most advanced design
and construction practices to combat
corrosion, HYUNDAI 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 is also
required.
Common causes of corrosion
The most common causes of corro-
sion on your vehicle are:
Road salt, dirt and moisture that is
allowed to accumulate underneath
the vehicle.
coatings by stones, gravel, abra-
sion or minor scrapes and dents
which leave unprotected metal
exposed to corrosion.
After washing the vehicle, test
the brakes while driving slowly
to see if they have been affected
by water. If braking performance
is impaired, dry the brakes by
applying them lightly while
maintaining a slow forward
speed.
WARNING
Do not use abrasive cleaner,
polishing compound, solvent,
or wire brushes on aluminum
or chrome wheels.
Clean the wheel when it has
cooled.
Use only a mild soap or neu-
tral detergent, and rinse thor-
oughly with water. Also, clean
the wheels after driving on
salted roads.
Do not wash the wheels with
high-speed car wash brushes.
Do not use any cleaners con-
taining acid or alkaline deter-
gents.
