Failure to observe these precautions
could result in damage to the catalyt-
ic converter and to your vehicle.
Additionally, such actions could void
your warranties.
Diesel Particulate Filter
(if equipped)
The Diesel Particulate Filter (DPF)
system 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 driving condition burns
and removes the accumulated soot.
However, if the vehicle continues to
be driven at repeated short distance
or driven at low speed for a long
time, the accumulated soot may not
be automatically removed because
of low exhaust gas temperature.
More than a certain amount of soot
deposited, the malfunction indicator
light ( ) illuminates.
Maintenance
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 ~ 2500 engine rpm for a
certain time (for about 25 minutes).
If the malfunction indicator light (
continues to be blinked or the warn-
ing massage "Check exhaust system"
illuminates in spite of the procedure,
please visit an authorised Kia dealer
and the 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.
