Problems with the perfume atomiser
Problem
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 anew pre-filled vial.
X Refillable vials: refill the vial with amaximum of 15 ml of the same
perfume. The perfume atomiser is faulty.
X Have the perfume atomiser checked at aqualified 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,d irectly, be perceived in the vehicle inte-
rior.
You can switch ionisation on or off using the
multimedia system (Y page 300).
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 arisk of fatal injuries.
You should switch off the auxiliary heating in
enclosed spaces which do not have an extrac- tion system, e.g. agarage. 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 asufficient supply of fresh air, open
aw indow 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 arisk 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-han dside of the vehicle. The
emissions outlet is found behind the front wheel on the right-han dside of the vehicle. 138
Operating the climate control systemClimatec
ontrol

!
Operating the auxiliary heating/ventilation
draws on the vehicle battery. After you have
heated or ventilated the vehicle amaximum of
two times, drive for alonger distance.
Switch the auxiliary heating on regularly once a
month for aboutt en 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 tank content
must be at least at reserve fuel level to ensure
that the auxiliary heating functions.
The auxiliary heating or auxiliary ventilation
automaticallya djusts 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 automaticallya fter 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 atemperature lower than
the outside temperature.
Before switchingon X
Turn the key to position 2in the ignition lock
(Y page 145).
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 manuallys et 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 centrec onsole
(Y page 139)
R using the remote control (Y page 140)The remote control can be used to set up to
three departure times, one of which may be pre-
selected.

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 aqualified specialist workshop.
Storet he 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 arange of approximately
300 metres. This range is reduced by:
R sources of radio interference
R solid objectsb etween 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 141).
