Draining water from fuel filter

The fuel filter for diesel engine plays
an important role of separating water
from fuel and accumulating the water
in its bottom.
If water accumulates in the fuel filter,
the warning light comes on when the
ignition switch is in the ON position.
If this warning light turned
on, we recommend that the
system be serviced by an
authorized HYUNDAI dealer.
NOTICE
If the water accumulated in the
fuel filter is not drained at proper
times, damages to the major parts
such as the fuel system can be
caused by water permeation in the
fuel filter.

tem as it makes it difficult to start the
engine.

mately 50 times until the pump is
hard.
