Ionisation is used to purify and freshen the air
in the vehicle interior, which is conducive to a
pleasant climate.
The ionisation of the interior air is odourless
and cannot, directly, be perceived in the vehi- cle interior.
You can switch ionisation on or off using
Audio 20 or COMAND Online (see the sepa-
rate operating instructions).
Ionisation can only be operated when the
automatic climate control is switched on. The
side air vent on the driver's side must be
open. Pre-entry climate control via key

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
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.
The auxiliary heating is fitted under the front
wing on the right-hand side of the vehicle. The emissions outlet is found behind the front
wheel on the right-hand side of the vehicle.
! Operating the auxiliary heating/ventila-
tion draws on the vehicle battery. After you have heated or ventilated the vehicle a
maximum of two times, drive for a longer
distance.
Switch the auxiliary heating on regularly once a month for about ten minutes.
The auxiliary heating heats the air in the vehi-
cle interior to the set temperature. This
occurs without using the heat of the running
engine. The auxiliary heating is operated
directly using the vehicle's fuel. For this rea-
son, the tank content must be at least at
reserve fuel level to ensure that the auxiliary
heating functions.
The auxiliary heating or auxiliary ventilation
automatically adjusts to changes in temper-
ature and weather conditions. For this rea-
son, the auxiliary heating could switch from
ventilation mode to heating mode or from
heating mode to ventilation mode.
The auxiliary heating switches off when the
engine is switched off. The auxiliary ventila-
tion is not active if the engine is running.
The auxiliary heating or auxiliary ventilation
switches off automatically after 50 minutes.
This time limit can be altered. To do this, visit a qualified specialist workshop.
You cannot use the auxiliary ventilation to
cool the vehicle interior to a temperature
lower than the outside temperature. 178

heating so that the auxiliary heating cannot
be switched on unintentionally. In particular,
ensure that the remote control for the auxili-
ary heating is kept out of the reach of chil-
dren.
The remote control has a range of approx-
imately 300 metres. This range is reduced by:
R sources of radio interference
R solid objects between the remote control
and the vehicle
R the remote control being in an unfavoura-
ble position in relation to the vehicle
R transmitting from an enclosed space
