If the coolant level is low, add enough dis-
tilled (deionized) water.
Bring the level to F (Full), but do not over-
fill. If frequent additions are required, we
recommend that the system be inspected
by an authorized HYUNDAI dealer.
WARNING
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.
• 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 counterclockwise to remove
it.
• Even if the engine is not operating, do
not remove the radiator cap or the
drain plug while the engine and radi-
ator are hot. Hot coolant and steam
may still blow out under pressure,
causing serious injury.
WARNING
The electric motor (cooling
fan) is controlled by engine
coolant temperature, refrig-
erant pressure and vehicle
speed. It may sometimes
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 rotat-
ing fan blades. As the engine coolant
temperature decreases, the electric mo-
tor will automatically shut off. This is a
normal condition.
The electric motor (cooling fan) may op-
erate until you disconnect the negative
battery cable.
