Glow indicator
(Diesel engine)
The indicator illuminates when the igni-
tion switch is in the ON position. The
engine can be started after the preheat
indicator light goes off. The illuminating
time varies with the water temperature,
air temperature and battery condition.
✽ NOTICE
If the engine does not start within 10
seconds after the preheating is complet-
ed, turn the ignition key once more to
the LOCK position for 10 seconds, and
then to the ON position, in order to pre-
heat again.
CAUTION
If the preheat indicator light contin-
ues to illuminate or blink on and off
after the engine has warmed up or
while driving, we recommend that
the system be checked by an
authorized HYUNDAI dealer.
D150329APB
Fuel filter warning light
(Diesel engine)
This warning light illuminates for 3 sec-
onds after the ignition switch is set to the
ON position and then it will go off. If it
lights up while the engine is running, it
indicates that water has accumulated
inside the fuel filter. If this happens,
remove the water from the fuel filter. For
more Information, refer to "Fuel filter" in
section 7.
CAUTION
When the fuel filter warning light
illuminates, the engine power (vehi-
cle speed & idle speed) may
decrease. If you keep driving with
the warning light on, you may dam-
age your vehicle's engine parts and
injection system of the Common
Rail. If this occurs, we recommend
that the system be checked by an
authorized HYUNDAI dealer.
