Always switch thest ationary heater off
in enclosed spaces without an air
ex traction sy stems, e.g. in garage s. #
Keep theta ilpipe and the area around
th eve hicle free from snow when the

The hot-water auxiliary hea ter has a heater boos‐
te r,stationary heater and stationary ventilation
function. In addition, the auxiliary heating sy stem
heats the engine coolant toprotect the engine.
The stationary heater automatically adapts its
operating mode tochanges in outside temp era‐
ture and weather conditions. It is therefore possi‐
ble that thest ationary heater may swit chfrom
ve ntilation toheating mode or from heating to
ve ntilation mode.
The stationary heater will automatically swit ch
itself off af ter a maximum of 50 minutes. The
heater boos ter function helps toheat up theve hi‐
cle while the engine is running and at low outside
te mp eratures.
Yo u can set up tothre e departure times for pre-
entry clima tecontrol byremo tecontrol or via the
multimedia sy stem. The switch-on time is then
calculated based on the outside temp erature and
th e activated departure time. This means that
yo ur vehicle is preheated or precooled bythe set
departure time.
If th e departure time is reached and the engine is
not star ted, the auxiliary heating will continue to Climate cont

s on short-distance trips
If th eve hicle is predominantly used in short-dis‐
ta nce driving, a fault in the automatic cleaning
function of the diesel particulate filter can occur.
Due tothis, fuel may also accumulate in the
engine oil and cause engine failure.
During automatic cleaning, extreme lyhot exhaust
ga ses escape from theex haust pipe. Maintain a
dis tance of at least 1 m to other objects, e.g.
par kedve hicles, in order toavoid material dam‐
age.
If yo u main lydrive short dis tances, you should
drive on a mo torw ay or go for a country drive for
20 minutes every500 km. This facilitates the
re ge neration of the diesel particulate filter.

Heavy and light loads
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
qu ickly in the air flow.
If th e brakes ha vebeen used only moderately,
yo u should occasionally test their ef fectiveness.
To do this, brake more firm ly from a higher speed
while pa ying attention tothe traf fic conditions.
The brakes will grip better as a result.
We tro ad sur faces
If yo u ha vebeen driving for a long time in heavy
ra in without braking, there may be a dela yed
re sponse when youfirs t apply the brakes. This
may also occur af ter driving thro ugh a car wash
or deep water.Yo u must depress the brake pedal
more firm ly. Maintain a grea ter dis tance tothe

While paying attention tothe traf fic conditions,
yo u should brake theve hicle firm lyafte r driving
on a wetro ad sur face or thro ugh a car wash. This
heats the brake disks so that they dry more

R a layer of salt on the brake disks or brakepads
can increase braking dis tances considerably,
or braking may happen on only one side
R maintain an especially large safe dis tance to
