207Driving and operation
If it illuminates briefly, but does not recur, it
is of no significance.
Illumination of A can indicate water in the
diesel fuel filter 3, at the same time a
message appears in the service display,
see page 120. Have a workshop check the
fuel filter for possible water residue.
If it flashes after the ignition is switched on,
there is a fault in the immobiliser system.
The engine cannot be started, see page 31.
Exhaust gases
During the first drive smoke may develop
because of wax and oil evaporating on the
exhaust system. Park the vehicle in the
open for a while after the first drive and
avoid inhaling the fumes.
Diesel particle filter 3
The diesel particle filter system removes
polluting soot particles out of the engine
exhaust gases. The system includes a self-
cleaning function that operates
automatically while driving. The filter is
cleaned by burning the trapped soot
particles at a high temperature. There may
be an increase in fuel consumption,
exhaust smell, and engine cooling fan
operation 3 during the self-cleaning
operation.
9 Warning
Engine exhaust gases contain poisonous
carbon monoxide, which is colourless and
odourless and could be fatal if inhaled.
If exhaust gases penetrate the vehicle
interior, open a window and contact a
workshop.
Avoid driving with an open luggage
compartment. Otherwise, exhaust gases
could penetrate the interior.
