34WHAT TO DO IN AN EMERGENCY
IF THE ENGINE OVERHEATS
!!
!
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.
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 add coolant to the reservoir
(page 6-9) 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.
D030A02A-AATIf 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).

DO-IT-YOURSELF MAINTENANCE

G050B01A-AATRecommended Engine CoolantUse a high quality ethylene-glycol coolant in a
50/50 mix with water. The engine coolant should
be compatible with aluminum engine parts.
Additional corrosion inhibitors or additives should
not be used. The cooling system must be
maintained with the correct concentration and
type of engine coolant to prevent freezing and
corrosion. Never allow the concentration of
antifreeze to exceed the 60% level or go below
the 35% level, or damage to the cooling system
may result. For proper concentration when
adding or replacing the engine coolant, refer to
the following table.

G050C01NF-GATTo Check the Coolant LevelThe coolant level can be seen on the side of the
plastic coolant reservoir. The level of the cool-
ant should be between the "L" and "F" lines on
the reservoir when the engine is warm with it at
idle . If the level is below the "L" mark, add engine
coolant to bring it up to "F". If the level is low,
inspect for coolant leaks and recheck the fluid
level frequently. If the level drops again, visit
your Hyundai dealer for an inspection and
diagnosis of the reason.
G050C01NFG050D01NF-GAT
To Change the Engine CoolantThe engine coolant should be changed at those
intervals specified in the vehicle maintenance
schedule in Section 5.
CAUTION:
o Engine coolant can damage the finish of
your car. If you spill engine coolant on
the car, wash it off thoroughly with clean
water.
o The engine in your vehicle has alumi-
num engine parts and must be protected
by an ethylene-glycol base coolant to
prevent corrosion and freezing.
Do not use hard water. Hard water can
cause engine damage from corrosion,
overheating or freezing.
!
1. Park the car on level ground, set the parking
brake and remove the radiator cap when
cool.

CATALYTIC CONVERTERH020A01A-AATAll 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:Catalytic Converter
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.
H020A01NF
o Remember that your Hyundai dealer is
your best source of assistance.
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.
