•  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. We recommend that all 
inspections and adjustments must 
be made by an authorised Retailer of 
Genesis Branded Products.
•  Avoid driving with an extremely low 
fuel level.
Running out of fuel could cause the 
engine to misfire, damaging the 
catalytic converter.
Petrol Particulate Filter (GPF)  
(if equipped)
Petrol 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 Petrol Particulate Filter (GPF) lamp 
stops illuminating, when the driving 
speed exceeds 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 authorised retailer 
of Genesis Branded products.
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 petrol fuels, when your 
vehicle is equipped with the GPF 
system.
When you use other petrol fuels which 
contain unspecified additives, they 
may damage the GPF system and cause 
exhaust emission problems.
