Auxiliary heating (auxiliary warm-air
heater)
Important safety notes
G
DANGER
If the exhaust pipe is blocked or sufficient
ventilation is not possible, toxic exhaust
fumes can enter the vehicle, especially car-
bon monoxide. This is the case, e.g. in
enclosed spaces, or if the vehicle is stuck in
snow. There is a risk of fatal injuries.
You should switch off the auxiliary heating in
enclosed spaces which do not have an extrac-
tion system, e.g. a garage. If the vehicle is
stuck in snow and you must leave the auxiliary
heating running, keep the exhaust pipe and
the area around the vehicle clear of snow. To
guarantee a sufficient supply of fresh air, open
a window on the side of the vehicle away from
the wind.
G
DANGER
If you switch on the auxiliary heating and have
a mounted awning, exhaust fumes could enter
the awning. There is a risk of fatal injuries.
Always switch off the auxiliary heating if peo-
ple are in the awning.
G
DANGER
If a switch-on time has been selected, the
auxiliary heating switches on automatically.
R
If the ventilation is insufficient, poisonous
exhaust gases can collect, in particular car-
bon monoxide. This is the case in enclosed
spaces, for example. There is a risk of fatal
injuries.
R
If highly flammable substances or flamma-
ble materials are nearby, there is a risk of a
risk of fire and explosion.
Always deactivate the preselected switch-on
times if you stop the vehicle in such or similar
situations.
G
WARNING
When the auxiliary heating is switched on,
very hot air can be discharged from the vent
on the rear side of the driver's seat base. This
may cause burns in the immediate proximity
of the vent. There is a risk of injury.
Make sure that vehicle occupants always
maintain a sufficient distance to the vent.
G
WARNING
When the auxiliary heating is switched on,
parts of the vehicle can become very hot.
Flammable materials such as leaves, grass or
twigs may ignite if they come into contact
with:
R
hot parts of the exhaust system
R
the exhaust gas itself
There is a risk of fire.
When the auxiliary heating is switched on,
make sure that:
R
no flammable materials come into contact
with hot vehicle components
R
the exhaust gas can escape from the
exhaust pipe unhindered
R
the exhaust gas does not come into contact
with flammable materials.
G
WARNING
Vehicles with an auxiliary warm-air heater:
If work on the heat exchanger of the auxiliary
warm-air heater is not performed correctly,
exhaust fumes could leak into the passenger
compartment. There is a risk of poisoning,
possibly even fatal.
You should have all work on the auxiliary
warm-air heater carried out at a qualified spe-
cialist workshop.
!
Switch on the auxiliary heating at regular
intervals (at least once a month) for approx-
imately ten minutes.
Make sure that the flow of hot air is not
blocked. The auxiliary heating would other-
wise overheat and switch off.
