CAUTION - Diesel Fuel
(if equipped with DPF)
It is recommended to use the regu-
lated automotive diesel fuel for
diesel vehicle equipped with the
DPF system.
If you use diesel fuel including high
sulfur (more than 50 ppm sulfur)
and unspecified additives, it can
cause the DPF system to be dam-
aged and white smoke can be emit-
ted.
Diesel Particulate Filter
(if equipped)
Type A
The Diesel Particulate Filter (DPF) sys-
tem removes the soot emitted from the
vehicle.
Unlike a disposable air filter, the DPF
system automatically burns (oxidizes)
and removes the accumulated soot
according to the driving condition. In
other words, the active burning by engine
control system and high exhaust gas
temperature caused by normal/high driv-
ing condition burns and removes the
accumulated soot.
However, if the vehicle continues to be
driven at low speed for long time, the
accumulated soot may not be automati-
cally removed because of low exhaust
gas temperature. In this particular case,
the amount of soot is out of detection
limit, the soot oxidation process by
engine control system may not happen
and the malfunction indicator light may
blink.
When the malfunction indicator light
blinks, it may stop blinking by driving the
vehicle at more than 60 km/h (37 mph) or
at more than second gear with 1500 ~
2000 engine rpm for a certain time (for
about 25 minutes).
If the malfunction indicator light contin-
ues to be blinked in spite of the proce-
dure, we recommend that the DPF sys-
tem be checked by an authorized
HYUNDAI dealer.
If you continue to drive with the malfunc-
tion indicator light blinking for a long time,
the DPF system can be damaged and
fuel consumption can be worsen.
Type B
The Diesel Particulate Filter (DPF) sys-
tem removes the soot in the exhaust gas.
Unlike a disposable air filter, the DPF
system automatically burns (oxidizes)
and removes the accumulated soot
according to the driving condition. In
other words, the active burning by engine
control system and high exhaust gas
temperature caused by normal/high driv-
ing condition burns and removes the
accumulated soot.
However, if the vehicle continues to be
driven at repeated short distance or driv-
en at low speed for a long time, the accu-
mulate soot may not be automatically
removed because of low exhaust gas
temperature. More than a certain amount
of soot deposited, the malfunction indica-
tor light ( ) illuminates.
When the malfunction indicator light
blinks, it may stop blinking by driving the
vehicle at more than 60km/h (37 mph) or
at more than second gear with 1500 ~
2500 engine rpm for a certain time (for
about 25 minutes).
