Heating and air conditioning system

WARNING
•The auxiliary heating must never be op erated in closed rooms - risk of
poisoning!
•The auxiliary heating must not be running during refueling - risk of fire.
•The exhaust pipe of the auxiliary heating is located on the underside of
the vehicle. Therefore do not place the vehicle, if you wish to operate the
auxiliary heating, in such a way that the exhaust gases of the auxiliary
heating can come easily into contact with inflammable materials (e.g. dry
grass) or easily inflammable substances (e.g. fuel run out).
Note
•If the auxiliary heating runs, the fuel consumption comes from the vehicle tank.
Therefore the auxiliary heating should not be operated, if there is very little fuel in
the tank.
•The exhaust pipe of the auxiliary heating, which is located on the underside of
the vehicle, must not be clogged and the exhaust flow must not be blocked.
•If the auxiliary heating and ventilation is running, the vehicle battery discharges.
If the auxiliary heating and ventilation has been operated several times over a
longer period, the vehicle must be driven a few kilometers in order to recharge the
vehicle battery.
•The auxiliary heating only switches the bl ower on, if it has achieved a coolant
temperature of approx. 50 °C.
•At low outside temperatures, this can resu lt in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operating
problem.
•After switching off the auxiliary heatin g, the coolant pump runs for a short
period.
•The auxiliary heating and ventilation does not switch on or comes on, if the
vehicle battery indicates a low loading state.
•The auxiliary heating (auxiliary heating) does not switch on, if the following was
shown in the information display or before switching off the ignition: Please
refuel! .
•When driving, the auxiliary heating can only be switched on, if the exterior
temperature is lower than 5 °C.
•The air inlet in front of the windscreen must be free of ice, snow or leaves in
order to ensure that the auxili ary heating operates properly.
•So that warm air can flow into the vehi cle interior after switching on the auxil-
iary heating, you must maintain the te mperature normally selected by you (we
recommend 22°C). It is recommended to put the air flow in the position
.
•On vehicles with DPF (diesel particle filter) the warm coolant heats up the
engine.
Using the system
So that the auxiliary heating (auxiliary heating and ventilation) func-
tions according to your expectations, it is necessary to carry out the
basic setting before its programming.
Basic setting
– On the information display, select from the Main menu the menu
point Setup (settings).
– From the menu Settings select Aux. heating (auxiliary heating).
– In the menu Aux. heating (auxiliary heating) ⇒ fig. 141 select the
menu point Weekday and set the current day.

Fuse cover in engine compartment
The fuse box in the engine comp artment exists in two different
versions. You can determine which vers ion your vehicle is fitted with
after removing the fuse cover at the location of the fuses.
For particular model versions, the battery must be removed before
removing the fuse cover ⇒page 232.
Removing fuse cover
– Move the circlips ⇒fig. 236 as far as the stop, the symbol

appears behind the circlip and remove the cover.
Installing fuse cover
– Position the fuse cover on the fuse box and push the circlips as far as the stop - the symbol
 is visible behind the circlip.
Caution
•When unlocking and locking the fuse cover, it must be pressed on the sides to
the box, otherwise damage can occur to the locking mechanism.
•Carefully position the fuse cover in the engine compartment. If the cover was
not correctly positioned, water can get into the fuses and this results in a damage
to the vehicle!
