In addition, there are components built into the

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. *

On long and steep downhill gradients you should

so that the engine is running at a medium to
high engine speed (/ page 143).
R invehicles with a manual transmission, shiT

engine is running at a medium tohigh engine
speed.
% Change the shiT range in good time when
cruise control or the limiter are activated.
Obser vethe driving tips (/ page 137).
Yo uth ereby make use of the braking e.ect of the
engine and do not ha vetobrake as oTen tomain-
ta in the speed. This relie vesth e load on the
service brake and pr events the brakes from over-
heating and wearing tooqu ickl y.

If th e brakes ha vebeen subjected toa heavy load,
do not stop theve hicle immediatel y.Drive on for a
short while. The brakes cool down more quickly in
th e air0o w.
If th e brakes ha vebeen used only moderatel y,you
should occasionally test their e.ectiveness. Todo
th is, brake more /rmly from a higher speed while
paying attention tothe tra1c conditions. The
brakes will grip better as a result.

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

re sponse when you /rst apply the brakes. This may
also occur aTer driving thro ugh a car wash or deep
wa ter. Yo u must depress the brake pedal more
/rml y.Maintain a greater distance totheve hicle in

While paying attention tothe tra1c conditions, you
should brake theve hicle /rml yaTer driving on a

th e brake disks so that they dry more quickl y,
