Engine exhaust
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,
open windows and contact a workshop
for assistance.
Avoid driving with the tailgate open,
since exhaust gas can enter the interior
of the vehicle.
Diesel particle filter 3
The diesel particle filter system filters
harmful soot particles out of the exhaust
gases. The system includes a self-cleaning
function that run automatically during
driving. The filter is cleaned by burning off
the soot particles at high temperature. This
process takes place automatically under
set driving conditions and may take up
to 25 minutes. Fuel consumption may be
higher during this period. The emission of
smells and smoke during this process is
normal.
