Gasoline Particulate Filter (GPF)
(if equipped)
The Gasoline Particulate Filter (GPF)
system removes the soot in the ex-
haust gas.
The GPF system automatically burns
(or oxidizes) the accumulated soot in
accordance with driving situations,
unlike a disposable air filter.
In other words, the accumulated soot
is automatically purged out by the en-
gine control system and by the high
exhaust-gas temperature at normal/
high driving speeds.
However, when the vehicle is contin-
ually driven at repeated short distanc-
es or driven at low speed for a long
time, the accumulated soot may not
be automatically removed because of
low exhaust gas temperature. In this
case, the accumulated soot may
reach a certain amount regardless of
the soot oxidization process, then the
GPF lamp will illuminate.
The Gasoline Particulate Filter (GPF)
Lamp stops illuminating, when the
driving speed exceeds 80 km/h (50
mph) with engine rpm 1,500 ~ 4,000
and the gear in the 3rd position or
above for approximately 30 minutes.
When the GPF lamp starts to blink or
the waning message "Check exhaust
system" pops up even though the ve-
hicle was driven as mentioned above,
we recommend that you have the
GPF system checked by an autho-
rized HYUNDAI dealer.
With the GPF lamp blinking for an ex-
tended period of time, it may damage
the GPF system and lower the fuel
economy.
WARNING
Gasoline Fuel
(if equipped with GPF)
We recommend you to use only
the regulated gasoline fuels, when
your vehicle is equipped with the
GPF system.
When you use other gasoline fuels
which contain unspecified addi-
tives, they may damage the GPF
system and cause exhaust emis-
sion problems.
