If th eve hicle is predominantly used in short-dis-
ta nce driving, a fault in the automatic cleaning
function of the diesel particulate /lter can occur.
Due tothis, fuel may also accumulate inthe engine
oil and cause engine failure.
During automatic cleaning, extremely hot exhaust
ga ses escape from theex haust pipe. Main tain a
distance of at least 1 m toother objects, e.g.
par kedve hicles, in order toavo id material damage.
If yo u mainly drive short distances, you should
drive on a mo torw ay or go for a country drive for
20 minutes every 500 km. This facilitates the
re ge neration of the diesel particulate /lter.

WARNING
ARNING Risk of accident due tothe
brake system overheating
If yo u lea veyour foot on the brake pedal when
driving, the brake system may overheat.
This increases the braking distance and the
brake system can even fail. #
Never use the brake pedal as a foot re st. #
Do not depress the brake pedal and the
accelerator pedal at the same time while
driving. *

Yo uth ereby make use of the braking e.ect of the

If th e brakes ha vebeen used only moderatel y,you
should occasionally test their e.ectiveness. Todo

If yo u ha vebeen driving for a long time in heavy
