The Gasoline Particulate Filter (GPF) is the system that removes the soot from the exhaust gas. Unlike a disposable air filter, the GPF system automatically burns (oxidizes) and removes the accumulated soot while driving.
However, repeated short-distance driving
or long-distance driving at a low
speed can stop the accumulated soot
from automatically being removed by
the GPF system. If the accumulated
soot reaches a certain amount, the GPF
warning light () will illuminate.
To reoperate
the GPF system, the vehicle
should be driven for more than 30 minutes
at a speed of 80km/h (50 mph)
and faster. Ensure the following conditions
are met: safe road conditions,
transmission 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 GPF system
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 professional workshop and check the GPF system. Kia recommends to visit an authorized Kia dealer/service partner. Constant driving with the GPF warning light on can damage the GPF system and undermine fuel economy.
