Maintenance
• Avoid driving with an extremely low
fuel level. Running out of fuel could
cause the engine to misfire, dam-
aging the catalytic converter.
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.
Petrol Particulate Filter (GPF) (if
equipped)
The Petrol Particulate Filter (GPF) is
the system that removes the soot
from the exhaust gas. Unlike a dis-
posable air filter, the GPF system
automatically burns (oxidizes) and
removes the accumulated soot whilst
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 re-operate 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, 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 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 pro-
fessional workshop and check the
GPF system. Kia recommends to
visit an authorised Kia dealer/service
partner. Constant driving with the
GPF warning light on can damage
the GPF system and undermine fuel
economy.
