The high-pressure cooling system
has a reservoir filled with year-round
antifreeze coolant. The reservoir is
filled at the factory.
Check the antifreeze protection and
coolant level at least once a year, at
the beginning of the winter season,
and before traveling to a colder cli-
mate.
Do not drive with no engine
coolant. It may cause water
pump failure and engine seizure,
etc.
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.Checking the coolant level
NOTICE
Removing radiator
cap
Never attempt to remove the
radiator cap while the engine
is operating or hot. Doing so
might lead to cooling system
and engine damage and could
result in serious personal
injury from escaping hot
coolant or steam.

WARNING
(Continued)
Turn the engine off and wait
until it cools down. Use
extreme care when removing
the radiator 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 counter-
clockwise to remove it.
Even if the engine is not oper-
ating, do not remove the radi-
ator cap or the drain plug
while the engine and radiator
are hot. Hot coolant and
steam may still blow out
under pressure, causing seri-
ous injury.

Recommended engine coolant
Use only soft (distilled) water in the
coolant mixture.
The engine in your vehicle has alu-
minum engine parts and must be
protected by a phosphate-based
ethylene glycol coolant for alu-
minum radiator based coolant to
prevent corrosion and freezing.
DO NOT USE alcohol or methanol
coolant or mix them with the spec-
ified coolant.
Do not use a solution that contains
more than 60% antifreeze or less
than 35% antifreeze, which would
reduce the effectiveness of the
solution.
For mixture percentage, refer to the
following table.
Changing the coolant
We recommend that the coolant be
replaced by an authorized HYUNDAI
dealer.
Put a thick cloth or fabric around
the radiator cap before refilling
the coolant in order to prevent the
coolant from overflowing into
engine parts such as the alterna-
tor.

Do not use radiator coolant or
antifreeze in the washer fluid

Radiator coolant can severely
obscure visibility when sprayed
on the windshield and may
cause loss of vehicle control or
damage to paint and body trim.
