The Lean NOx Trap (LNT) system
removes the nitrogen oxide in the
exhaust gas. The smell can occur in the
exhaust gas depending on the quality of
the fuel and it can degrade NOx reduc-
tion performance, please use the regulat-
ed automotive diesel fuel.
If you continue to drive with the malfunc-
tion indicator light blinking for a long time,
the DPF system can be damaged and
fuel consumption can be worsen.
However, if the vehicle continues to be
driven at repeated short distance or driv-
en at low speed for a long time, the accu-
mulated soot may not be automatically
removed because of low exhaust gas
temperature.
CAUTION - Diesel Fuel
