WARNING
WL_RadiatorHotWarning
Never remove the engine coolant cap
or the drain plug while the engine and
radiator are hot.
Hot coolant and steam may blow out
under pressure, causing serious injury.
Turn off the engine and wait until the
engine cools down. Use extreme care
when removing the coolant cap. Wrap a
thick towel around it, and turn it
counterclockwise slowly to the first
stop. Step back while the pressure is
released from the cooling system.
When you are sure all the pressure has
been released, press down on the cap,
using a thick towel, and continue
turning counterclockwise to remove it.
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, 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, contact an
authorized HYUNDAI dealer for
assistance.
CAUTION
• Serious loss of coolant indicates a leak
in the cooling system. Have your
vehicle inspected 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 quantities. It
may require several refilling cycles to
properly fill the engine cooling system.
If necessary, contact an authorized
HYUNDAI dealer.
