facility, continue to apply water to the affect-
ed 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 bat-
tery, 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 order shown on the previous page.
That is, 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 solid metal 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 sev-
eral minutes.
6. Following the exact reverse order of their
being attached, carefully remove the jumper
cables. Remove the negative cable first,
then the positive cable.
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.

IF THE ENGINE OVERHEATS

If your temperature gauge indicates overheating,
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).
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 en-
gine 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 serious
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
