The hot-water auxiliary heater has a heater boos-
te r,stationary heater and stationary ventilation
function.
The stationary hea ter automatically adapts its
operating mode tochanges in outside temp erature
and weather conditions. It is therefore possible
th at the stationary heater may switch from ventila-
tion toheating mode or from heating toventilation
mode.
The stationary hea ter will automatically switch
itself o. aTer a maximum of 50 minutes. The
heater booster 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 climate control byremo tecont rol or via the
multimedia system. The switch-on time is then cal-
culated based on the outside temp erature and the
activated departure time. This means that your
ve hicle is preheated or precooled bythe set depar-
ture time.
If th e departure time is reached and theve hicle is
not star ted, the auxiliary heating will continue to
ru nfo r appr oximately /ve more minutes. It will
th en switch o. automaticall y.
When the auxiliary heating is heating and theve hi-
cle is star ted, the heater booster function of the
auxiliary heating will be activated.
When the auxiliary heating is ventilating and 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
obser vethefo llowing inst ructions:
R invehicles with an automatic transmission,

so that the engine is running at a medium to

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
ra in without braking, there may be a dela yed
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
we tro ad sur face or thro ugh a car wash. This heats
th e brake disks so that they dry more quickl y,
which pr otects them against cor rosion. 138 138
