Switching the residual heat on/off
General notes
It is possible to make use of the residual heat of
the engine to continue heating the stationary
vehicle for up to 30 minutesafter the engine has
been switched off. The heating time depends on
the set interior temperature.

Ionisation
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 vehicle inte-
rior.
You can switch ionisation on and off via the mul-
timedia system (see the separate operating
instructions).
Ionisation can only be operated when the auto-
matic climate control is switched on. The side air
vent on the driver's side must be open.
Auxiliary heating
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 left-hand side of the vehicle. The
emissions outlet is found behind the left front
wheel.
!
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.
