WHAT TO DO IN AN EMERGENCY 3- 3
o If you should accidentally get acid on your
skin or in your eyes, immediately remove
any contaminated clothing and flush the area
with clear water for at least 15 minutes. Then
promptly obtain medical attention. If you
must be transported to an emergency facil-
ity, continue to apply water to the affected
area with a sponge or cloth.
o The gas produced by the battery during the
jump-start operation is highly explosive. Do
not smoke or allow a spark or an open flame
in the vicinity.
o The battery being used to provide the jump
start must be 12-volt. If you cannot deter-
mine that it is a 12-volt battery, do not attempt
to use it for the jump start.
o To jump start a car with a discharged battery,
follow this procedure exactly:
1. If the booster battery is installed in another
vehicle, be sure the two vehicles are not
touching.
2. Turn off all unnecessary lights and acces-
sories in both vehicles.
3. Attach the clamps of the jumper cable in the
exact location shown on the illustration. First,
attach one clamp of the jumper cable to the
positive (+) post or cable of the discharged
battery. Then attach the other end of the
same cable to the positive (+) post or cable
of the booster battery. Next, using the other
cable, attach one clamp to the negative (-)
post or cable of the booster battery. Then
attach the other end of that cable to a solidmetal part of the engine away from the
battery. Do not connect the cable to any
moving part.
4. Start the engine in the car with the booster
battery and let it run for a few minutes. This
will help to assure that the booster battery is
fully charged. During the jumping operation,
run the engine in this vehicle at about 2,000
rpm.
5. Start your engine using the normal starting
procedure. After the engine starts, leave the
jumper cables connected and let the engine
run at fast idle or about 2,000 rpm for several
minutes.
6. Carefully remove the jumper cables in the
reverse order of attachment.
If you do not know why your battery became
discharged (because the lights were left on,
etc.), have the charging system checked by
your Hyundai dealer.D030A01A-AATIF THE ENGINE OVERHEATS
If your temperature gauge indicates overheat-
ing, you experience a loss of power, or hear loud
pinging or knocking, the engine is probably too
hot. If this happens, you should:
1. Pull off the road and stop as soon as it is safe
to do so.
2. Place the gear selector lever in "P" (auto-
matic), or neutral (manual transaxle) and set
the parking brake. If the air conditioning is on,
turn it off.
3. If engine coolant is running out under the car
or steam is coming out from the hood, stop
the engine. Do not open the hood until the
coolant has stopped running or the steaming
has stopped. If there is no visible loss of
engine coolant and no steam, leave the
engine running and check to be sure the
engine cooling fan is operating. If the fan is
not running, turn the engine off.
4. Check to see if the water pump drive belt is
missing. If it is not missing, check to see that
it is tight. If the drive belt seems to be
satisfactory, check for coolant leaking from
the radiator, hoses or under the car. (If the
air conditioning had been in use, it is normal
for cold water to be draining from it when you
stop).

3- 4 WHAT TO DO IN AN EMERGENCY
!
!WARNING:While the engine is running, keep hair,
hands and clothing away from moving parts
such as the fan and drive belts to prevent
injury.
D040A01Y-AATSPARE TIRE
The following instructions for the temporary
spare tire should be observed:
1. Check inflation pressure as soon as practi-
cal after installing the spare tire, and adjust
to the specified pressure. The tire pressure
should be periodically checked and main-
tained at the specified pressure while the tire
is stored.
Tire Size
Inflation Pressure
T125/80R15
60 psi (420 kPa) 5. If the water pump drive belt is broken or
engine coolant is leaking out, stop the engine
immediately and call the nearest Hyundai
dealer for assistance.
WARNING:Do not remove the radiator cap when the
engine is hot. This can allow coolant to be
blown out of the opening and cause seri-
ous burns.
6. If you cannot find the cause of the overheat-
ing, wait until the engine temperature has
returned to normal. Then, if coolant has been
lost, carefully remove the radiator cap and
add coolant to bring the fluid level in the
reservoir up to the halfway mark.
7. Proceed with caution, keeping alert for fur-
ther signs of overheating. If overheating
happens again, call a Hyundai dealer for
assistance.
CAUTION:Serious loss of coolant indicates there is a
leak in the cooling system and this should
be checked as soon as possible by a Hyundai
dealer.
!
4. As the temporary spare tire is specifically
designed for your car, it should not be used
on any other vehicle.
5. The temporary spare tire should not be used
on any other wheels, nor should standard
tires, snow tires, wheel covers or trim rings
be used with the temporary spare wheel. If
such use is attempted, damage to these
items or other car components may occur.
6. The temporary spare tire pressure should
be checked once a month while the tire is
stored.
Spare Tire Pressure
2. The spare tire should only be used tempo-
rarily and should be returned to the luggage
compartment as soon as the original tire can
be repaired or replaced.
3. Continuous use at speeds of over 50 mph
(80 km/h) is not recommended.
CAUTION:o Do not use snow chains with your tem-
porary spare tire.
o Do not use more than one temporary
spare tire at a time.

EMISSION CONTROL SYSTEMS 7- 3
!WARNING:o Use unleaded fuel only.
o Maintain the engine in good operating
condition. Extremely high catalytic con-
verter temperatures can result from im-
proper operation of the electrical, igni-
tion or multiport electronic fuel injec-
tion.
o If your engine stalls, pings, knocks, or is
hard to start, have your Hyundai dealer
inspect and repair the problem as soon
as possible.
o Avoid driving with a very low fuel level.
Running out of gasoline may cause the
engine to misfire and result in damage to
the catalytic converter.
o Avoid idling the engine for periods
longer than 10 minutes.
o The vehicle should not be pushed or
pulled to get started. This may cause the
catalytic converter to overheat and cre-
ate a fire hazard.
o Do not touch the catalytic converter or
any other part of the exhaust system
while the catalytic converter is hot. Shut
off the engine, wait for at least one hour
before touching the catalytic converter
or any other part of the exhaust system.
o Remember that your Hyundai dealer is
your best source of assistance.
H020A01A-AATCATALYTIC CONVERTER
All Hyundai vehicles are equipped with a mono-
lith type three-way catalytic converter to re-
duce the carbon monoxide, hydrocarbons and
nitrogen oxides contained in the exhaust gas.
Exhaust gases passing through the catalytic
converter cause it to operate at a very high
temperature. The introduction of large amounts
of unburned gasoline into the exhaust may
cause the catalytic converter to overheat and
create a fire hazard. This risk may be reduced
by observing the following:o Do not stop your Hyundai over any com-
bustible material such as grass, paper,
leaves or rags. These materials might
contact the hot catalytic converter and a
fire might result.
