k k
Exhaust gas temperature may become higher than the pre-
vious models during the aftertreatment devices regenera-
tion. Avoid getting near the exhaust pipe outlet and around
the aftertreatment devices to prevent being burnt. Also, do
not bring any combustible material close to the outlet of
the exhaust pipe or the aftertreatment devices to prevent a
fire.
The manual stationary regeneration can be performed while
the KDPF soot accumulation caution lamp (1) is lit.
