Maintenance Emission control system
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void
your warranties.
Petrol Particulate Filter (PPF) (if
equipped)
The Petrol Particulate Filter (PPF) is the
system that removes the soot from the
exhaust gas. Unlike a disposable air fil
-
ter, the PPF system automatically burns
(oxidizes) and removes the accumulated
soot whilst driving.
However, repeated short-distance driv
-
ing or long-distance driving at a low
speed can stop the accumulated soot
from automatically being removed by
the PPF system. If the accumulated soot
reaches a certain amount, the PPF warn
-
ing light ( ) will illuminate. To re-
operate the PPF system, the vehicle
should be driven for more than 30 min
-
utes at a speed of 80km/h (50 mph) and
faster. Ensure the following conditions
are met: safe road conditions, transmis
-
sion 3 or above, and engine speed of
1,500-4,000 rpm. Driving at 80 km/h
(50 mph) or faster for recommended
hours will get the PPF system back to
work and stop the PPF warning light.
If the PPF warning light stays on or the
warning message “Check exhaust sys
-
tem” pops up even after driving at rec
-
ommended speed and for
recommended hours, visit a professional
workshop and check the PPF system.
Kia recommends to visit an authorised
Kia dealer/service partner. Constant
driving with the PPF warning light on
can damage the PPF system and under
-
mine fuel economy.
