The Diesel Particulate Filter (DPF)
Lamp stops illuminating, when the
driving speed exceeds 37mph (60
km/h), or when the engine rpm is
between 1,500 and 2,500 with the
gear in the 2nd position or above for
approximately 25 minutes.
When the DPF Lamp continuously
blinks or the warning message
“Check exhaust system” illuminates
in the above cases, we recommend
that you have the DPF system
checked by a HYUNDAI authorised
repairer.
When the vehicle is continuously
driven with the DPF Lamp flashing
for an extended period of time, it may
damage the DPF system and lower
the fuel economy.Lean NOx Trap (if equipped)
The Lean NOx Trap (LNT) system
removes the nitrogen oxide from the
exhaust gas. A smell can occur in the
exhaust gas depending on the quali-
ty of the fuel, and it can degrade NOx
reduction performance. Please use
the regulated automotive diesel fuel.

Maintenance
Diesel Fuel
(if equipped with DPF)
We recommend you to use only
the regulated diesel fuels, when
your vehicle is equipped with
the DPF system.
When you use other diesel
fuels, which are high in sulfurs
(above 50 ppm) or that contain
unspecified additives, they may
damage the DPF system and
cause white smoke emissions.
