Maintenance
Turn the engine off and wait
until it cools down. Use
extreme care when removing
the coolant cap. Wrap a thick
towel around it, and turn it
anticlockwise slowly to the
first stop. Step back whilst 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 anticlockwise to
remove it.
Even if the engine is not oper-
ating, do not remove the
coolant cap or the drain plug
whilst the engine and radiator
are hot. Hot coolant and
steam may still blow out
under pressure, causing seri-
ous injury.
The electric motor
(cooling fan) is con-
trolled by engine
coolant temperature,
refrigerant pressure
and vehicle speed. It may some-
times operate even when the
engine is not running. Use
extreme caution when working
near the blades of the cooling
fan so that you are not injured
by a rotating fan blades. As the
engine coolant temperature
decreases, the electric motor
will automatically shut off. This
is a normal condition.
The electric motor (cooling fan)
may operate until you discon-
nect the negative battery cable.
WARNING
Make sure the coolant cap is
properly closed after refilling
coolant. Otherwise the engine
could be overheated whilst
driving
1. Check if the coolant cap label
is straight In front.

Maintenance
Changing the coolant
We recommend that the coolant be
replaced by an authorised HYUNDAI
dealer.
Put a thick cloth or fabric
around the coolant cap before
refilling the coolant in order to
prevent the coolant from over-
flowing into engine parts such
as generator.
CAUTION
Coolant
Do not use radiator coolant or
antifreeze in the washer fluid
reservoir.
Radiator coolant can severely
obscure visibility when
sprayed on the windscreen
and may cause loss of vehicle
control or damage to paint
and body trim.
