the on-board computer has prompted you to
do so with corresponding event windows.

indicator lamp lights up in the
instrument cluster and the engine speed is
increased.

you have parked the vehicle for an exten-
ded period without performing regenera-
tion

regulations. Wear gloves and a dust protection
mask. Pack and seal the removed diesel parti-
cle filter in the original packaging. Label the
removed diesel particle filter and under no cir-
cumstances leave it unpacked in the open.
