Maintenance
accumulated soot reaches a certain
amount, the GPF warning light
( ) will illuminate. To re-operate
the GPF system, the vehicle should
be driven for more than 30 minutes
at a speed of 80 km/h and faster.
Ensure the following conditions are
met: safe road conditions, trans -
mission 3 or above, and engine
speed of 1,500 ~ 4,000 rpm. Driving
at 80 km/h or faster for recom -
mended hours will get the GPF sys -
tem back to work and stop the GPF
warning light.
If the GPF warning light stays on or
the warning message "check
exhaust system" pops up even after
driving at recommended speed and
for recommended hours, visit a pro -
fessional workshop and have them
check the GPF system. Constant
driving with the GPF warning light
on can damage the GPF system and
undermine fuel economy.
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 (oxi -
dizes) and removes the accumulated
soot according to the driving condi -
tion. In other words, the active
burning by engine control system
and high exhaust gas temperature
caused by normal/high driving con -
dition burns and removes the accu -
mulated soot. However, if the
vehicle continues to be driven at
repeated short distance or driven at
low speed for a long time, the accu -
mulated soot may not be automati -
cally 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 driv -
ing 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
warning massage "Check exhaust
system" illuminates in spite of the
procedure, visit a professional
workshop and check the DPF sys -
tem. Kia recommends to visit an
authorised Kia dealer/service part -
ner. If you continue to drive with the
malfunction indicator light blinking
for a long time, the DPF system can
be damaged and fuel consumption
can be worsen and engine durability
can be worsen by oil dilution.
CAUTION
Diesel Fuel (if equipped with DPF)
It is recommended to use the regu -
lated automotive diesel fuel for die -
sel vehicle equipped with the DPF
system.
