WARNING:
o No objects should be placed over or near
the airbag modules on the steering
wheel, instrument panel, and the front
passenger's panel above the glove box,
because any such object could cause
harm if the vehicle is in a crash severe
enough to cause the airbags to deploy.
o If the airbags deploy, they must be re-
placed by an authorized Hyundai dealer.
o Do not tamper with or disconnect SRS
wiring or other components of the SRS
system. Doing so could result in injury,
due to accidental deployment of the
airbags or by rendering the SRS inopera-
tive.
o Even though your vehicle is equipped
with the occupant classification sys-
tem, do not install a child restraint sys-
tem in the front passenger seat position.
A child restraint system must never be
placed in the front seat. The infant or
child could be severely injured or killed
by an airbag deployment in case of an
accident.
o Do not allow children to ride in the front
passenger seat. If older children (teen-
agers and older) must ride in the front
seat, make sure they are always properly
belted and the seat is moved back as far
as possible.
o For maximum safety protection in all
types of crashes, all occupants includ-
ing the driver should always wear their
seat belts whether or not an airbag is
also provided at their seating position to
minimize the risk of severe injury or
death in the event of a crash. Do not sit
or lean unnecessarily close to the airbag
while the vehicle is in motion.
o Sitting improperly or out of position can
result in serious or fatal injury in a crash.
All occupants should sit upright with
the seat back in an upright position,
centered on the seat cushion with their
seat belt on, legs comfortably extended
and their feet on the floor until the ve-
hicle is parked and the ignition key is
removed.
o The SRS airbag system must deploy very
rapidly to provide protection in a crash.
If an occupant is out of position because
of not wearing a seat belt, the airbag may
forcefully contact the occupant causing
serious or fatal injuries.

B240D01NF-AATAdditional Safety PrecautionsoNever let passengers ride in the cargo
area (trunk) or on top of a folded-down
back seat. All occupants should sit upright,
fully back in their seats with their seat belts
on and their feet on the floor.
oPassengers should not move out of or
change seats while the vehicle is mov-
ing. A passenger who is not wearing a seat
belt during a crash or emergency stop can
be thrown against the inside of the vehicle,
against other occupants, or out of the ve-
hicle.
oEach seat belt is designed to restrain one
occupant. If more than one person uses the
same seat belt, they could be seriously
injured or killed in a collision.
oDo not use any accessories on seat
belts. Devices claiming to improve occu-
pant comfort or reposition the seat belt can
reduce the protection provided by the seat
belt and increase the chance of serious
injury in a crash.oPassengers should not place hard or
sharp objects between themselves and
the airbags. Carrying hard or sharp objects
on your lap or in your mouth can result in
injuries if an airbag inflates.
oKeep occupants away from the airbag
covers. All occupants should sit upright, fully
back in their seats with their seat belts on and
their feet on the floor. If occupants are too
close to the airbag covers, they could be
injured if the airbags inflate.
oDo not attach or place objects on or near
the airbag covers. Any object attached to
or placed on the front or side impact airbag
covers could interfere with the proper opera-
tion of the airbags.
oDo not modify the front seats. Modifica-
tion of the front seats could interfere with the
operation of the supplemental restraint sys-
tem sensing components or side impact
airbags.
oDo not place items under the front seats.
Placing items under the front seats could
interfere with the operation of the supple-
mental restraint system sensing compo-
nents and wiring harnesses.
o If the airbags inflate, they must be re-
placed by an authorized Hyundai dealer.
o Do not tamper with or disconnect SRS
wiring, or other components of the SRS
system. Doing so could result in injury,
due to accidental inflation of the airbags
or by rendering the SRS inoperative.
o If components of the airbag system must
be discarded, or if the vehicle must be
scrapped, certain safety precautions
must be observed. Your Hyundai dealer
knows these precautions and can give
you the necessary information. Failure
to follow these precautions and proce-
dures could increase the risk of personal
injury.
o If you sell your vehicle, make certain that
this manual is transferred to the new
owner.
o If your car was flooded and has soaked
carpeting or water on flooring, you
shouldn't try to start the engine; have
the car towed to an authorized Hyundai
dealer.

C160H02A-AATUse Approved Window Washer Anti-
Freeze in SystemTo keep the water in the window washer system
from freezing, add an approved window washer
anti-freeze solution in accordance with instruc-
tions on the container. Window washer anti-
freeze is available from Hyundai dealers and
most auto parts outlets. Do not use engine
coolant or other types of anti-freeze as these
may damage the paint finish.C160G01A-AATTo Keep Locks from FreezingTo keep the locks from freezing, squirt an
approved de-icer fluid or glycerine into the key
opening. If a lock is covered with ice, squirt it with
an approved de-icing fluid to remove the ice. If
the lock is frozen internally, you may be able to
thaw it out by using a heated key. Handle the
heated key with care to avoid injury.
C160F01A-AATCheck Spark Plugs and Ignition
SystemInspect your spark plugs as described in Sec-
tion 6 and replace them if necessary. Also
check all ignition wiring and components to be
sure they are not cracked, worn or damaged in
any way.C160E01A-AATChange to "Winter Weight" Oil if
NecessaryIn some climates it is recommended that a lower
viscosity "winter weight" oil be used during cold
weather. See Section 9 for recommendations.
If you aren't sure what weight oil you should use,
consult your Hyundai dealer.
C160D01A-AATCheck Battery and CablesWinter puts additional burdens on the battery
system. Visually inspect the battery and cables
as described in Section 6. The level of charge
in your battery can be checked by your Hyundai
dealer or a service station.C160C01A-AATUse High Quality Ethylene Glycol
CoolantYour Hyundai is delivered with high quality
ethylene glycol coolant in the cooling system. It
is the only type of coolant that should be used
because it helps prevent corrosion in the cool-
ing system, lubricates the water pump and
prevents freezing. Be sure to replace or replen-
ish your coolant in accordance with the main-
tenance schedule in Section 5. Before winter,
have your coolant tested to assure that its
freezing point is sufficient for the temperatures
anticipated during the winter.

ANY QUESTIONS?
E040D01A-AATCleaning the Seat BeltsTo 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 CarpetsUse 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-AATIf you have any questions about the care of your
car, consult your Hyundai dealer.
E040E01A-AATCleaning the WindowsYou 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.

DO-IT-YOURSELF MAINTENANCE
25
Drive belts should be checked periodically for
proper tension. At the same time, belts should
be examined for cracks, wear, fraying or other
evidence of deterioration and replaced if neces-
sary.
When a new belt is replaced, the belt should be
located within the pulley of flat idler.
Belt routing should also be checked to be sure
there is no interference between the belts and
other parts of the engine.
NOTE:Drive belt tension is adjusted automatically
by the auto tensioner.
CHECKING AND REPLACING
FUSESG200A01A-AATReplacing a Fusible LinkA fusible link will melt if the electrical circuits from
the battery are ever overloaded, thus prevent-
ing damage to the entire wiring harness. (This
could be caused by a short in the system
drawing too much current.) If this ever happens,
have a Hyundai dealer determine the cause,
repair the system and replace the fusible link.
The fusible links are located in a relay box in the
engine compartment for easy inspection.

!
CAUTION:
When replacing a fusible link, never use
anything but a new fusible link with the
same or lower amperage rating. Never use
a piece of wire or a higher-rated fusible link.
This could result in serious damage and
create a fire hazard.
