WARNING
•The auxiliary heating must never be operated 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 su bstances (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 heat ing 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 sw itches the blower 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 heating, the coolant pump runs for a short
period.
•The auxiliary heating and ventilation does not switch on or comes on, if the
vehicle battery indicate s a low loading state.
•The auxiliary heating (auxiliary heating) switches on, if in the information
display: Please refuel! is indicated or was indicated before switching off the igni-
tion.
•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 mu st be free of ice, snow or leaves in
order to ensure that the auxiliary heating operates properly.
•So that the warm air can flow into the vehicle interior after switching on the
auxiliary heating (auxiliary heating), the control dial ⇒page 100, fig. 119 must
be turned up to the stop to the right when heating. With Climatic and Climatronic,
you can maintain the temperature norma lly selected by you (we recommend 22
°C). It is recommended to put the air flow in the position
. For heating and
climatic put the blower switch ⇒page 100, fig. 119 if necessary ⇒page 104,
fig. 122 in the position 2.
•On vehicles with DPF (die sel particle filter) the warm coolant heats up the
engine.
