WARNING
ARNING Risk of burns due torepeatedly
switching on the seat heating
Re peatedly switching on the seat heating can
cause the seat cushion and seat backrest pad-
ding tobecome very hot.
In particular, the health of persons with limited
te mp erature sensitivity or a limited ability to
re act tohigh temp eratures may be a.ected or
th ey may even su.er burn-like injuries. #
Do not repeatedly switch on the seat
heating. To
protect against overheating, the seat heating
may be temp orarily deactivated aTer it is switched
on repeatedl y.

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.

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. #

Yo uth ereby make use of the braking e.ect of the
engine and do not ha vetobrake as oTen tomain-

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,
which pr otects them against cor rosion. 138 138
