Maintenance
NOTICE
• 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 an extended period of time (5
minutes or more).
• Do not modify or tamper with any part
of the engine or emission control
system. We recommend that all
inspections and adjustments must be
made by an authorized HYUNDAI
dealer.
• Avoid driving with an extremely low
fuel level.
Running out of fuel may cause the
engine to misfire, damaging the
catalytic converter.
Failure to follow these precautions may
void your vehicle warranty.
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.
9-76
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 (
illuminates.
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
warning 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 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.
