What to do in an emergency

IF THE ENGINE OVERHEATS

F050000AFD-EA
If your temperature gauge indicates over-
heating, you experience a loss of power,
or hear loud pinging or knocking, the
engine is probably too hot. If this hap-
pens, 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
(automatic transaxle) or neutral (man-
ual transaxle) and set the hand 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
underneath the bonnet, stop the
engine. Do not open the bonnet 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 cool-
ing fan is operating. If the fan is not
running, turn the engine off.
4. While engine is switched off, 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 con-
ditioning 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 engine immediately and call the
nearest authorised HYUNDAI dealer
for assistance.
WARNING
Do not remove the radiator cap
when the engine is hot. This may
result in coolant being blown out of
the opening and cause serious
burns.
6. If you cannot find the cause of the
overheating, wait until the engine tem-
perature has returned to normal. Then,
if coolant has been lost, carefully add
coolant to the reservoir to bring the
fluid level in the reservoir up to the
halfway mark.
7. Proceed with caution, keeping alert for
further signs of overheating. If over-
heating happens again, call an autho-
rised 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 an authorised
HYUNDAI dealer.
