What to do in an emergency If the engine overheats
If the engine overheats
If your temperature gauge indicates
overheating, you will experience a loss
of power, or hear loud pinging or knock
-
ing, 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 shift lever in P (automatic
transmission/dual clutch transmis
-
sion) or neutral (manual transmission)
and set the parking brake. If the air
conditioning is on, turn it off.
3. If engine coolant is running out under
the vehicle or steam is coming out
from 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 cooling fan is operat
-
ing. 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 satisfac
-
tory, check for coolant leaking from
the radiator, hoses or under the vehi
-
cle. (If the air conditioning had been in
use, it is normal for cold water to be
draining from it when you stop).
WARNING
whilst 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 a
professional workshop. Kia recom

WARNING
Do not remove the radiator cap when
the engine is hot. This can allow coolant
to blow out of the opening and cause
serious burns.
6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to nor
-
mal.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
overheating happens again, call a
professional workshop. Kia recom
