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.

parts of the vehicle can become very hot.

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

R
the exhaust gas can escape from the
exhaust pipe unhindered
R

!
Operating the auxiliary heating/ventilation
draws on the vehicle battery. After you have
heated or ventilated the vehicle a maximum of
two times, drive for a longer distance.
Only vehicles with auxiliary heating have this
function.
In the
Heating
Heating
submenu, you can select a
stored departure time or change a departure
time.
The auxiliary heating timer function calculates
the switch-on time according to the outside
temperature so that the vehicle is preheated by
the departure time. When the departure time is
reached, the auxiliary heating continues to heat
for a further five minutes and then switches off.
The auxiliary heating adopts the set air condi-
tioning or THERMOTRONIC temperature set-
ting.
You can switch off the auxiliary heating by using
the remote control or the auxiliary heating but-
ton on the centre console.
i
Switch the auxiliary heating on regularly
once a month for about ten minutes.
