overheating, wait until the engine
temperature has returned to nor-

alert for further signs of overheat-
ing. If over heating happens again,
call the nearest authorized Kia
dealer for assistance.

NOTICE
Serious loss of coolant indicates
there is a leak in the cooling system
and should be checked as soon as
possible by an authorized Kia dealer.
CAUTION
When the engine overheats from
low engine coolant, suddenly
adding engine coolant may
cause cracks in the engine. To
prevent damage, add engine
coolant slowly in small quantities
