Diesel Particulate Filter
(if equipped)
The Diesel Particulate Filter (DPF)
system removes the soot emitted
from the vehicle.
Unlike a disposable air filter, the DPF
system automatically burns (oxi-
dizes) and removes the accumulated
soot according to the driving condi-
tion. In other words, the active burn-
ing by engine control system and
high exhaust gas temperature
caused by normal/high driving condi-
tion burns and removes the accumu-
lated soot.
However, if the vehicle continues to
be driven at low speed for long time,
the accumulated soot may not be
automatically removed because of
low exhaust gas temperature. In this
particular case, the amount of soot is
out of detection limit, the soot oxida-
tion process by engine control sys-
tem may not happen and the mal-
function indicator light may blink.
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 ~ 2000 engine rpm for a
certain time (for about 25 minutes).
If the malfunction indicator light con-
tinues to be blinked in spite of the
procedure, please visit an authorized
HYUNDAI dealer and then check the
DPF system.
If you continue to drive with the mal-
function indicator light blinking for a
long time, the DPF system can be
damaged and fuel consumption can
be worsen.
CAUTION -
Diesel Fuel
(if equipped with DPF)
It is recommended to use the
regulated 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 addi-
tives, it can cause the DPF sys-
tem to be damaged and white
smoke can be emitted.
