iliary heating.
When the engine is switched off, it is possible to
make use of the residual heat of the engine to
continue heating or ventilating the front com-
partment of the vehicle for approximately
30 minutes. The heating or ventilation time
depends on the set interior temperature.

WARNING
If children open the vial, they could drink the
perfume or it could come into contact with
their eyes. There is a risk of injury. Do not
leave children unsupervised in the vehicle.
If the perfume liquid has been drunk, consult
a doctor. If perfume comes into contact with
your eyes or skin, rinse the eyes with clean
water. If you continue to experience difficul-
ties, consult a doctor. H
Environmental note Full vials must not be dis-
posed of with household
waste. They must be collec-
ted separately and disposed

Possible causes/consequences and
M
MSolutions The vehicle interior is not
perfumed although the
perfume atomiser has
been activated. The perfume vial has not been pushed into the holder as far as it will
go.
X Slide the perfume vial into the holder as far as it will go. The perfume vial is not filled sufficiently.
X Pre-filled vials: dispose of the empty vial.
X Use a new pre-filled vial.
X Refillable vials: refill the vial with a maximum of 15 ml of the same
perfume. The perfume atomiser is faulty.
X Have the perfume atomiser checked at a qualified specialist work-
shop. 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 or off using the
multimedia system (Y page 297).
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 unit 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 climate control system

!
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.
Switch the auxiliary heating on regularly – once a month – for about ten minutes.
The auxiliary heating heats the air in the vehicle
interior to the set temperature. This occurs with- out using the heat of the running engine. The
auxiliary heating is operated directly using the
vehicle's fuel. For this reason, the fuel tank level
must be above the reserve range to ensure that the auxiliary heating functions.
The auxiliary heating or auxiliary ventilation
automatically adjusts to changes in tempera-
ture and weather conditions. For this reason,
the auxiliary heating could switch from ventila-
tion mode to heating mode or from heating
mode to ventilation mode.
The auxiliary heating switches off when the
engine is switched off. The auxiliary ventilation
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, consult
a qualified specialist workshop.
You cannot use the auxiliary ventilation to cool
the vehicle interior to a temperature lower than
the outside temperature.
Before switching on X
Turn the key to position 2in the ignition lock
(Y page 144).
X Set the desired temperature using the w
rocker switch on the front control unit.
If you do not alter the temperature before
switching on the auxiliary heating or auxiliary
ventilation, the last temperature setting will be
adopted.
Auxiliary heating or auxiliary ventilation can also be switched on if the manually set climate con-
trol is activated. Optimum comfort is attained
when the system is set to automatic mode. Set
the temperature to 22 †.
You can switch the auxiliary heating or auxiliary
ventilation on or off:
R using the rocker switch on the centre console
(Y page 138)
R using the remote control (Y page 139)The remote control can be used to set up to
three departure times, one of which may be pre- selected.

Switching the auxiliary heating/venti-
lation on or off using the remote control
General notes
Your vehicle comes with one remote control.
You may use two additional remote controls for
your vehicle. For more information, please con-
tact a qualified specialist workshop.
Store the remote control for the auxiliary heat-
ing so that the auxiliary heating cannot be
switched on unintentionally. In particular,
ensure that the remote control for the auxiliary
heating is kept out of the reach of children.
The remote control has a range of approximately
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 unfavourable
position in relation to the vehicle
R transmitting from an enclosed space
If the remote control battery is low, the battery
symbol on the left of the display is shown as
empty. Replace the remote control battery and
observe the important safety notes when doing so (Y page 140).

WARNING
Very hot or very cold air can flow from the air vents. This could result in burns or frostbite in the immediate vicinity of the air vents. There
is a risk of injury.
Make sure that all vehicle occupants always
maintain a sufficient distance to the air out-
lets. If necessary, redirect the airflow to
another area of the vehicle interior. In order to ensure the direct flow of fresh air
through the air vents into the vehicle interior,
please observe the following notes:
R keep the air inlet between the windscreen and
the bonnet free of blockages, such as ice,
snow or leaves
R never cover the vents or ventilation grilles in
the vehicle interior Adjusting the air vents
