!WARNING:Do not get under the car when it is sup-
ported by the jack! This is very dangerous
as the vehicle could fall and cause serious
injury or death. No one should stay in the
car while the jack is being used.
D060G02Y-AAT6. Changing Wheels
D060H02A-AAT7. Reinstall Wheel Nuts
Loosen the wheel nuts and remove them with
your fingers. Slide the wheel off the studs and
lay it flat so it cannot roll away. To put the wheel
on the hub, pick up the spare tire, line up the
holes with the studs and slide the wheel onto
them. If this is difficult, tip the wheel slightly and
get the top hole in the wheel lined up with the top
stud. Then jiggle the wheel back and forth until
the wheel can be slid over the other studs.
WARNING:Wheels and wheel covers may have sharp
edges. Handle them carefully to avoid pos-
sible severe injury. Before putting the wheel
into place, be sure that there is nothing on
the hub or wheel (such as mud, tar, gravel,
etc.) that interferes with the wheel from
fitting solidly against the hub. If there is,
remove it. If there is not good contact on the
mounting surface between the wheel and
hub, the wheel nuts could come loose and
cause the loss of a wheel. Loss of a wheel
may result in loss of control of the vehicle.
This may cause serious injury or death.To reinstall the wheel, hold it on the studs, put
the wheel nuts on the studs and tighten them
finger tight. The nuts should be installed with
their small diameter ends directed inward. Jiggle
the tire to be sure it is completely seated, then
tighten the nuts as much as possible with your
fingers again.

Lower the car to the ground by turning the jack
handle counterclockwise. Then position the
wrench as shown in the drawing and tighten the
wheel nuts. Be sure the socket is seated com-
pletely over the nut. Do not stand on the wrench
handle or use an extension pipe over the wrench
handle.
Go around the wheel tightening every other nut
until they are all tight. Then double-check each
nut for tightness and reinstall the wheel cover.
After changing wheels, have a technician tighten
the wheel nuts to their proper torque as soon as
possible.

65-80 lb.ft (900-1,100 kg.cm)If you have a tire gauge, remove the valve cap
and check the air pressure. If the pressure is
lower than recommended, drive slowly to the
nearest service station and inflate to the correct
pressure. If it is too high, adjust it until it is correct.
Always reinstall the valve cap after checking or
adjusting tire pressure. If the cap is not re-
placed, air may leak from the tire. If you lose a
valve cap, buy another and install it as soon as
possible.
After you have changed wheels, always secure
the flat tire in its place in the trunk and return the
jack, jack handle, and tools to their proper
storage locations.
CAUTION:Your car can be damaged if towed incor-
rectly!
If your car has to be towed, it should be done by
your Hyundai dealer or a commercial tow truck
service. This will help assure that your car is not
damaged in towing. Also, professionals are
generally aware of state and local laws govern-
ing towing. In any case, rather than risk damage
to your car, it is suggested that you show this
information to the tow truck operator. Be sure
that a safety chain system is used and that all
state and local laws are observed.

o If the car is being towed with the rear wheels
on the ground, be sure the parking brake is
released.
o If the car is being towed with the front wheels
on the ground, be sure that the transaxle is
in neutral. Also, be sure that the ignition key
is in the "ACC" position. This is necessary to
prevent damage to the steering lock mecha-
nism, which is not designed to hold the front
wheels straight while the car is being towed.
o If any of the loaded wheels or suspension
components are damaged, a towing dolly
must be used.
CAUTION:A car with an automatic transaxle should
never be towed from the rear with the front
wheels on the ground. This can cause se-
rious damage to the transaxle. If the car
must be towed from the rear, a towing dolly
must be used under the front wheels.
If the car is being towed with the rear wheels on
the ground, be sure the parking brake is re-
leased.
NOTE:Before towing, check the level of the
transaxle fluid. If it is below the "HOT" mark
on the dipstick, add fluid. If you cannot add
fluid, a towing dolly must be used as de-
scribed above.!

D080D02A-AATEmergency Towing
For emergency towing when no commercial
tow vehicle is available, attach a tow cable,
chain or strap to one of the towing hooks under
the front of your car. Do not attempt to tow your
vehicle in this manner on any unpaved surface.
This could result in serious damage to your car.
Nor should towing be attempted if the wheels,
drive train, axles, steering or brakes are dam-
aged. Before towing, be sure the transaxle is in
neutral and the key is in "ACC" (with the engine
off) or in the "ON" position (with the engine
running). A driver must be in the towed car to
steer it and operate the brakes.

D120A01A-AATIF YOU LOSE YOUR KEYS
If you lose your keys, many Hyundai dealers
can make you a new key if you have your key
number.
If you lock the keys inside your car and you
cannot obtain a new key, many Hyundai dealers
can use special tools to open the door for you.
CAUTION:If the car is being towed with all four wheels
on the ground, it can be towed only from the
front. Be sure that the transaxle is in neutral.
Do not tow at speeds greater than 30 mph
(50 km/h) and for more than 15 miles (25
km). Be sure the steering is unlocked by
placing the key in the "ACC" position.

4- 2 CORROSION PREVENTION AND APPEARANCE CARE
E020B01A-AATKeep 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 particu-
larly 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.
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.
E020A01A-AAT
TO HELP PREVENT CORROSION
You can help prevent corrosion from getting
started by observing the following:
E010D01A-AATMoisture Breeds Corrosion
Moisture creates the conditions in which corro-
sion is most likely to occur. For example, cor-
rosion is accelerated by high humidity, particu-
larly when temperatures are just above freez-
ing. 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 the moisture and promote corro-
sion.
High temperatures can also accelerate corro-
sion 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 Areas
If you live in an area where your car is regularly
exposed to corrosive materials, corrosion pro-
tection 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 Corrosion
The 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-AATCORROSION PROTECTION
Protecting Your Hyundai from Corro-
sion
By using the most advanced design and con-
struction 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.

CORROSION PREVENTION AND APPEARANCE CARE 4- 3
E020E01A-AATDon't Neglect the Interior
Moisture 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, clean-
ing materials or chemicals in the car.
These should be carried only in proper contain-
ers and any spills or leaks should be cleaned up,
flushed with clear water and thoroughly dried.
E020D01A-AATKeep Paint and Trim in Good Condition
Scratches or chips in the finish should be
covered with "touch-up" paint as soon as pos-
sible to reduce the possibility of corrosion. If
bare metal is showing through, the attention of
a qualified body and paint shop is recommended.
E020C01A-AATKeep Your Garage Dry
Don'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 contrib-
ute to corrosion unless it is well ventilated so
moisture is dispersed.
E030A01A-AATWASHING AND WAXING
Washing Your Hyundai
Never 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 thor-
oughly 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 abra-
sive 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.
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 alumi-
num is subject to corrosion, be sure to give
aluminum alloy wheels special attention in win-
ter. 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.
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

4- 4 CORROSION PREVENTION AND APPEARANCE CARE
E040B01A-AATTo Clean the Leather Upholstery
(If installed)
In the normal course of use, leather upholstered
surfaces will, like any material, pick-up dust and
dirt. This dust and dirt must be cleaned off or it
may work into the surface of the leather, caus-
ing damage.
Fine leather needs care, and should be cleaned
when necessary. Washing leather thoroughly
with soap and water will keep your leather
lustrous, beautiful and ensure you have many
years of wear.
E040A01A-AATCLEANING THE INTERIOR
To Clean the Vinyl Upholstery
To clean the vinyl upholstery, first remove loose
dirt and dust with a vacuum cleaner. Then apply
a solution of mild soap or detergent and water
using a clean sponge or soft cloth. Allow this to
stay on the surface to loosen the dirt, then wipe
with a clean damp sponge or cloth. If all the dirt
stains are not removed, repeat this procedure
until the upholstery is clean. Do not use gaso-
line, solvent, paint thinner or other strong clean-
ers.
E030E01A-AATMaintaining Bumpers
Special precautions must be observed to pre-
serve the appearance of the bumpers on your
Hyundai. They are:
o Be careful not to spill battery electrolyte or
hydraulic brake fluid on the bumpers. If you
do, wash it off immediately with clear water.
o Be gentle when cleaning the bumper sur-
faces. They are made of soft plastic and the
surface can be damaged if mistreated. Do
not use abrasive cleaners. Use warm water
and mild soap or car-washing solution.
o Do not expose the bumpers to high tem-
peratures. For example, if you have your car
repainted, do not leave the bumpers on the
car if the car is going to be placed in a high-
temperature paint booth.
E030D01A-AATWhen to Wax Again
You should polish and wax the car again when
water no longer beads on a clean surface but
spreads out over a larger area.
E030C01A-AATPolishing and Waxing
Always wash and dry the car before polishing
or waxing or using a combination cleaner and
wax. Use a good quality commercial product
and follow the manufacturer's directions on the
container. Polish and wax the bright trim pieces
as well as the paint.
E030B01A-AAT
Spot Cleaning
Don't use gasoline, strong solvents or corro-
sive cleaning agents. These can damage the
finish of the car. To remove road tar, use
turpentine on a clean, soft cloth. Be gentle.
To remove dead insects or tree sap, use warm
water and mild soap or car-washing solution.
Soak the spot and rub gently. If the paint has lost
its luster, use a commercial car-cleaning polish. 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 solu-
tion. Be sure to rinse the surface after washing
to remove the solution. Never allow the solution
to dry on the painted surfaces.

CORROSION PREVENTION AND APPEARANCE CARE 4- 5
Take a piece of cheese cloth and using any mild
soap and lukewarm water, work up a good
lather. Thoroughly wash the leather. Wipe clean
with a slightly damp cloth and dry with soft cloth.
Do this as often as the leather becomes
soiled.
During tanning operations, sufficient oils are
incorporated through processing that none need
be applied during the life of the leather. Oil
applied to the finished surface will in no way help
the leather and may do more harm than good.
Varnishes and furniture polishes should never
be used under any conditions.E040D01A-AATCleaning the Seat Belts
To clean the seat belts, use a cloth or sponge
with mild soap or detergent and warm water. Do
not use strong detergents, dye, bleach or abra-
sive materials on the seat belts as this may
weaken the fabric.
While cleaning the belts, inspect them for ex-
cessive wear, cuts, fraying or other signs of
damage and replace them if necessary.
E040C01A-AATCleaning the Carpets
Use a foam-type carpet cleaner. Cleaners of
this type are available in aerosol cans in liquid
form or powder. Read the instructions and
follow them exactly. Using a vacuum cleaner
with the appropriate attachment, remove as
much dirt from the carpets as possible. Apply
the foam following the manufacturer's direc-
tions, then rub in overlapping circles. Do not add
water. These cleaners work best when the
carpet is kept as dry as possible.
E050A01A-AATAny Questions?
If you have any questions about the care of your
car, consult your Hyundai dealer.
E040E01A-AATCleaning the Windows
You may use any household window cleaner on
the windows. However, when cleaning the in-
side of the rear window be careful not to damage
the rear window defroster wiring.
