CORROSION PREVENTION AND APPEARANCE CARE2
CORROSION PROTECTION
E020B01A-AATKeep Your Car CleanThe best way to prevent corrosion is to
keep your car clean and free of corrosive
materials. Attention to the underside of the
car is particularly important.
o If you live in a high-corrosion area —
where road salts are used, near the
ocean, areas with industrial pollution,
acid rain, etc.—, you should take extra
care to prevent corrosion. In winter,
hose off the underside of your car at
least once a month and be sure to clean
the underside thoroughly when winter
is over.
o When cleaning underneath the car, give
particular attention to the components
under the fenders and other areas that
are hidden from view. Do a thorough
job; just dampening the accumulated
mud rather than washing it away will
accelerate corrosion rather than prevent
it. Water under high pressure and steam
are particularly effective in removing
accumulated mud and corrosive
materials.E020A01A-AATYou can help prevent corrosion from getting
started by observing the following:
E010D01A-AATMoisture Breeds CorrosionMoisture creates the conditions in which
corrosion is most likely to occur. For
example, corrosion is accelerated by high
humidity, particularly when temperatures
are just above freezing. In such conditions,
the corrosive material is kept in contact
with the car surfaces by moisture 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 the moisture and
promote corrosion.
High temperatures can also accelerate
corrosion of parts that are not properly
ventilated so the moisture can be dispersed.
For all these reasons, it is particularly
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.E010C01A-AATHigh-Corrosion AreasIf you live in an area where your car is
regularly exposed to corrosive materials,
corrosion protection is particularly
important. Some of the common causes of
accelerated corrosion are road salts, dust
control chemicals, ocean air and industrial
pollution.
E010B01A-AATCommon Causes of CorrosionThe most common causes of corrosion on
your car are:
o Road salt, dirt and moisture that is
allowed to accumulate underneath the
car.
o Removal of paint or protective coatings
by stones, gravel, abrasion or minor
scrapes and dents which leave
unprotected metal exposed to corrosion.E010A01A-AATProtecting Your Hyundai from Cor-
rosionBy 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 Hyundai can deliver, the
owner's cooperation and assistance is also
required.

WASHING AND WAXING
E020E01A-AATDon't Neglect the InteriorMoisture can collect under the floor mats
and carpeting to cause corrosion. Check
under the mats periodically to be sure the
carpeting is dry. Use particular care if you
carry fertilizers, cleaning materials or
chemicals in the car.
These should be carried only in proper
containers and any spills or leaks should
be cleaned up, flushed with clean water
and thoroughly dried.
E020C01A-AATKeep Your Garage DryDon't park your car in a damp, poorly
ventilated garage. This creates a favorable
environment for corrosion. This is
particularly true if you wash your car in the
garage or drive it into the garage when it is
still wet or covered with snow, ice or mud.
Even a heated garage can contribute to
corrosion unless it is well ventilated so
moisture is dispersed.
E030A02A-AATWashing Your HyundaiNever wash your car when the surface is
hot from being in the sun. Always wash
your car in the shade.
Wash your car frequently. Dirt is abrasive
and can scratch the paint if it is not removed.
Air pollution or acid rain may damage the
paint and trim through chemical action if
pollutants are allowed to remain in contact
with the surface. If you live near the ocean
or in an area where road salts or dust
control chemicals are used, you should
pay particular attention to the underside of
the car. Start by rinsing the car to remove
dust and loose dirt. In winter, or if you have
driven through mud or muddy water, be
sure to thoroughly clean the underside as
well. Use a hard direct stream of water to
remove accumulations of mud or corrosive
materials. Use a good quality car-washing
solution and follow the manufacturer's
directions on the package. These are
available at your Hyundai dealer or auto
parts outlet. Don't use strong household
detergents, gasoline, strong solvents or
abrasive cleaning powders as these may
damage the finish.
Use a clean sponge or cloth, rinse it
frequently and don't damage the finish by
rubbing too hard. For stubborn spots,
dampen them frequently and remove them
a little at a time. o When cleaning lower door panels,
rocker panels and frame members, be
sure that drain holes are kept open
so that moisture can escape and not
be trapped inside to ac-celerate
corrosion.
E020D02A-AATKeep Paint and Trim in Good
ConditionScratches or chips in the finish should be
covered with "touch-up" paint as soon as
possible to reduce the possibility of
corrosion. If bare metal is showing through,
the attention of a qualified body and paint
shop is recommended.
Bird droppings : Bird droppings are highly
corrosive and may damage painted
surfaces in just a few hours. Always remove
bird droppings as soon as possible.

CORROSION PREVENTION AND APPEARANCE CARE4
If you find any nicks or scratches in the
paint, use touch-up paint to cover them to
prevent corrosion. To protect the paintwork
of the car against corrosion, you must
clean your Hyundai (at least once a month).
Give special attention
to the removal of salt, mud and other sub-
stances on the underside of the
splashboards of the car. Make sure that the
outlets and the underside of the doors are
open. Paint damage can be caused by
small accumulation of tar, industrial
precipitation, tree resin, insects and bird
droppings, when not removed immediately.
If water alone is not strong enough to
remove the accumulated dirt, use a mild
car washing solution. Be sure to rinse the
surface after washing to remove the
solution. Never allow the solution to dry on
the painted surfaces. To clean whitewall tires, use a stiff brush or
soapy steel-wool scouring pad.
To clean plastic wheel covers, use a clean
sponge or soft cloth and water.
To clean cast aluminum alloy wheels, use
a mild soap or neutral detergent. Do not
use abrasive cleaners. Protect the bare-
metal surfaces by cleaning, polishing and
waxing. Because aluminum is subject to
corrosion, be sure to give aluminum alloy
wheels special attention in winter. If you
drive on salted roads, clean the wheels
thoroughly afterwards.
After washing, be sure to rinse thoroughly.
If soapy water dries on the finish, streaking
will result.
When the weather is warm and the humidity
low, you may find it necessary to rinse each
section immediately after washing to avoid
streaking.
After rinsing, dry the car using a damp
chamois or soft, absorbent cloth. The
reason for drying the car is to remove water
from the car so it will dry without water
spots. Don't rub, this can damage the finish.
CAUTION:
!
OJB037800
o Water washing in the engine compart-
ment including high pressure water
washing may cause the failure of elec-
trical circuits located in the engine
compartment.
o Never allow water or other liquids to
come in contact with electrical/elec-
tronic components inside the vehicle
as this may damage them.

the vehicle may be driven, damage the
emission system and cause hard starting.
If an excessive amount of foreign matter
accumulates in the fuel tank, the filter may
require replacement more frequently.
After installing a new filter, run the engine
for several minutes, and check for leaks at
the connections. Fuel filters should be
installed by trained technicians.
F060F01A-AATo Vacuum, Crankcase Ventilation
HosesInspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indicate
deterioration. Particular attention should
be paid to examine those hose surfaces
nearest to high heat sources, such as the
exhaust manifold.
Inspect the hose routing to assure that the
hoses do not come in contact with any heat
source, sharp edges or moving component
which might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are secure,
and that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.
