Maintenance
• Water washing in the engine
compartment including high
pressure water washing may
cause the failure of electrical cir-
cuits located in the engine com-
partment.
• Never allow water or other liq-
uids to come in contact with
electrical/electronic compo-
nents 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 main-
tain its luster. Removing oil, tar, and
similar materials with a spot remover
will usually strip the wax from the fin-
ish. Be sure to re-wax these areas
even if the rest of the vehicle does
not yet need waxing.
• 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-plat-
ed or anodized aluminum parts.
This may result in damage to the
protective coating and cause
discoloration or paint deteriora-
tion.

NOTICE
Wet brakes
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.

Maintenance
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.
If your vehicle is damaged and
requires any metal repair or
replacement, be sure the body
shop applies anti-corrosion materi-
als 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 preser-
vative 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
preservative. 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
collect on the underbody. If these
materials are not removed, acceler-
ated 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 under-
body and wheel openings with luke-
warm 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.

Maintenance
Aluminum wheel maintenance
The aluminum wheels are coated with
a clear protective finish.
• Do not use any abrasive cleaner,
polishing compound, solvent, or
wire brushes on aluminum
wheels.
• Clean the wheel when it has
cooled.
• Use only a mild soap or neutral
detergent, and rinse thoroughly
with water. Also, be sure to clean
the wheels after driving on salt-
ed roads.
• Do not wash the wheels with
high-speed car wash brushes.
• Do not use any cleanser con-
taining acid or alkaline deter-
gents.
Corrosion protection
Protecting your vehicle from corro-
sion
By using the most advanced design
and construction practices to combat
corrosion, we produces cars of the
highest quality. However, this is only
part of the job. To achieve the long-
term corrosion resistance your vehi-
cle can deliver, the owner's coopera-
tion and assistance is also required.
Common causes of corrosion
The most common causes of corro-
sion on your car are:
• Road salt, dirt and moisture that is
allowed to accumulate underneath
the car.
• Removal of paint or protective
coatings by stones, gravel, abra-
sion or minor scrapes and dents
which leave unprotected metal
exposed to corrosion.
NOTICE
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.

Maintenance
High-corrosion areas
If 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 cor-
rosion 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, partic-
ularly when temperatures are just
above freezing. In such conditions,
the corrosive material is kept in con-
tact 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 acceler-
ate corrosion of parts that are not
properly ventilated so the moisture
can be dispersed. For all these rea-
sons, 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.To help prevent corrosion
You can help prevent corrosion from
getting started by observing the fol-
lowing:Keep your car clean
The 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.
• 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.
• 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 damp-
ening the accumulated mud rather
than washing it away will acceler-
ate corrosion rather than prevent
it. Water under high pressure and
steam are particularly effective in
removing accumulated mud and
corrosive materials.

Maintenance
• When cleaning lower door panels,
rocker panels and frame mem-
bers, be sure that drain holes are
kept open so that moisture can
escape and not be trapped inside
to accelerate corrosion.
Keep your garage dry
Don't park your car in a damp, poor-
ly 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 cov-
ered with snow, ice or mud. Even a
heated garage can contribute to cor-
rosion unless it is well ventilated so
moisture is dispersed.Keep paint and trim in good con-
dition
Scratches 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 atten-
tion 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.Don't neglect the interior
Moisture can collect under the floor
mats and carpeting to cause corro-
sion. Check under the mats periodi-
cally to be sure the carpeting is dry.
Use particular care if you carry fertil-
izers, cleaning materials or chemi-
cals 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.

Interior care
Interior general precautions
Prevent chemicals such as perfume,
cosmetic oil, sun cream, hand clean-
er and air freshener from contacting
the interior parts because they may
cause damage or discoloration. If
they do contact the interior parts,
wipe them off immediately.
See the instructions that follow for
the proper way to clean vinyl.
Never allow water or other liquids
to come in contact with electri-
cal/electronic components inside
the vehicle as this may damage
them.When cleaning leather products
(steering wheel, seats etc.), use
neutral detergents or low alcohol
content solutions. If you use high
alcohol content solutions or
acid/alkaline detergents, the color
of the leather may fade or the sur-
face may get stripped off.
Cleaning the upholstery and
interior trim
Vinyl
Remove dust and loose dirt from
vinyl with a whisk broom or vacuum
cleaner. Clean vinyl surfaces with a
vinyl cleaner.
Fabric
Remove dust and loose dirt from fab-
ric with a whisk broom or vacuum
cleaner. Clean with a mild soap solu-
tion recommended for upholstery or
carpets. Remove fresh spots imme-
diately with a fabric spot cleaner. If
fresh spots do not receive immediate
attention, the fabric can be stained
and its color can be affected. Also, its
fire-resistant properties can be
reduced if the material is not proper-
ly maintained.
Using anything but recommended
cleaners and procedures may
affect the fabric’s appearance and
fire-resistant properties.

Cleaning the lap/shoulder belt
webbing
Clean the belt webbing with any mild
soap solution recommended for
cleaning upholstery or carpet. Follow
the instructions provided with the
soap. Do not bleach or re-dye the
webbing because this may weaken it.
Cleaning the interior window
glass
If the interior glass surfaces of the
vehicle become fogged (that is, cov-
ered with an oily, greasy or waxy
film), they should be cleaned with
glass cleaner. Follow the directions
on the glass cleaner container.
Do not scrape or scratch the
inside of the rear window. This
may result in damage to the rear
window defroster grid.

EMISSION CONTROL SYSTEM
The emission control system of your
vehicle is covered by a written limited
warranty. Please see the warranty
information contained in the Service
Passport in your vehicle.
Your vehicle is equipped with an
emission control system to meet all
emission regulations.
There are three emission control
systems which are as follows.
(1) Crankcase emission control sys-
tem
(2) Evaporative emission control sys-
tem
(3) Exhaust emission control system
In order to assure the proper function
of the emission control systems, it is
recommended that you have your
car inspected and maintained by an
authorized HYUNDAI dealer in
accordance with the maintenance
schedule in this manual.1. Crankcase emission control
system
The positive crankcase ventilation
system is employed to prevent air
pollution caused by blow-by gases
being emitted from the crankcase.
This system supplies fresh filtered air
to the crankcase through the air
intake hose. Inside the crankcase,
the fresh air mixes with blow-by
gases, which then pass through the
PCV valve into the induction system.
2. Evaporative emission con-
trol system
The Evaporative Emission Control
System is designed to prevent fuel
vapors from escaping into the atmos-
phere. For the Inspection and
Maintenance Test (With Electronic
Stability Control (ESC) system)
•To prevent the vehicle from
misfiring during dynamome-
ter testing, turn the Electronic
Stability Control (ESC) sys-
tem off by pressing the ESC
switch.
•After dynamometer testing is
completed, turn the ESC sys-
tem back on by pressing the
ESC switch again.
