6. If you cannot find the cause of the
overheating, wait until the engine
temperature has returned to normal.
Then, if coolant has been lost, careful-
ly 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, we rec-
ommend that you call an authorized
HYUNDAI dealer for assistance.
NOTICE
• Serious loss of coolant indicates a leak
in the cooling system and we recom-
mend the system be checked by an
authorized HYUNDAI dealer.
• 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 quanti-
ties.
