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. Menus and submenus

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.
! 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 isreached, the auxiliary heating continues to heat
for a further five minutes and then switches off. The auxiliary heating adopts the THERMATIC orTHERMOTRONIC temperature setting.
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.
