Your vehicle is equipped with a catalytic
converter emission control device.
To prevent damage to the catalytic
converter and to your vehicle, take the
following precautions:
[Use only UNLEADED FUEL for
gasoline engines.
[Do not operate the vehicle when
there are signs of engine malfunction,
such as misfire or a noticeable loss of
performance.
[Do not misuse or abuse the engine.
Examples of misuse are coasting with
the engine off and descending steep
grades in gear with the engine off.
[Do not operate the engine at high
idle speed for extended periods (5
minutes or more).
[Do not modify or tamper with any
part of the engine or emission
control system. Have all inspections
and adjustments are made by an
authorized HYUNDAI dealer.
[Avoid driving with an extremely low
fuel level.
Running out of fuel could cause the
engine to misfire, damaging the
catalytic converter.Gasoline Particulate Filter (GPF)
(if equipped)
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 50 mph (80 km/h)
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 warning message “Check exhaust
system” pops up even though the vehicle
was driven as mentioned above, have the
GPF system checked by an authorized
HYUNDAI dealer.
With GPF lamp blinking for an extended
period of time, it may damage the GPF
system and lower the fuel economy.
CAUTION
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.
