Maintenance
• Avoid driving with a very low fuel level.
If you run out of gasoline, it could
cause the engine to misfire and result
in excessive loading of the catalytic
converter.
Failure to observe these precautions
could result in damage to the catalytic
converter and to your vehicle.
Additionally, such actions could void
your warranties.
Gasoline Particulate Filter (GPF)
(if equipped)
The Gasoline Particulate Filter (GPF)
system removes the soot in the exhaust
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 engine
control system and by the high exhaust-
gas temperature at normal/ high driving
speeds.
However, when the vehicle is continually
driven at repeated short distances 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
vehicle was driven as mentioned above,
we recommend that you have the
GPF system checked by an authorized
HYUNDAI dealer.
With the GPF lamp blinking for an
extended 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 additives,
they may damage the GPF system and
cause exhaust emission problems.
