Pressing once switches the seat heating on at its maximum level.
With repeated pressing of the switch, the intensity of the heating is reduced
until it is switched off.
The level of the seat heating is indicated by the number of illuminated warning
lights underneath/in the switch.
If the engine is switched off and then turned on again within 10 mins with the
driver seat heating switched, then the driver's seat heating is automatically
turned on again.WARNINGIf, as a passenger, you have a subdued pain and/or temperature sensitivity,
e.g. through medication, paralysis or because of chronic illness (e.g. diabe-
tes), we recommend you do not use seat heating on the driver's or front
passenger seat. This can lead to burns on the back, the posterior and the
legs which are difficult to heal. If the seat heating is used, we recommend
to make regular breaks in your journey when driving long distances, so that
the body can recuperate from the stress of the journey. Please consult your
doctor, who can evaluate your specific condition.
CAUTION
■ Do not kneel on the seats or otherwise apply concentrated pressure to them.■The seat heating in the following cases will not turn on - there is a risk of
damaging the seat covers and seat heating. ■The seats are not occupied by people.
■ Items are fastened or stored items on the seats, such as a child seat, a bag
and the like.
■ Additional seat covers or protective covers are fixed to the seats.■

Air distribution control
Read and observe
and on page 116 first.
Recirculated air mode prevents polluted air from outside the vehicle getting in-
to the vehicle, for example when driving through a tunnel or when standing in
a traffic jam.
In recirculated air mode air is sucked out of the interior of the vehicle and then
fed back into the interior.

117Heating and air conditioning

Automatic activation/deactivation of the air recirculation
Climatronic may have an air quality sensor for the detection of the pollutant
concentration in the sucked-in air.
If a considerable increase in concentration of pollutants is recognised by the
air quality sensor, the recirculated air mode will be switched on automatically.
When the pollutant concentration decreases to the normal level, the recircula-
ted air mode is automatically switched off.
The automatic activation/deactivation of the air recirculation can be activated or deactivated in the Infotainment » Infotainment operating instructions ,
chapter Vehicle settings .WARNINGThe recirculation system cannot be switched on for a longer period of time,
because there is no supply of fresh air from the outside. “Stale air” may re-
sult in fatigue in the driver and occupants, reduce attention levels and also
cause the windows to mist up. The risk of having an accident increases.
Switch off recirculated air mode as soon as the windows start to mist up.
CAUTION
We recommend not smoking in the vehicle when the recirculating air operation
is switched on. The smoke sucked from inside the vehicle is deposited on the
evaporator of the air conditioner. This produces a permanent odour when the
air conditioning system is operating which can only be eliminated through con-
siderable effort and expense (replacement of compressor).
Note
The automatic activation/deactivation of the air recirculation with Climatronic
only works if the outside temperature is higher than approx. 2 °C.HeatingFig. 124

cator light in the button is lit).
The interior temperature can be set between +16 ℃ and +29.5 °C. The interior
temperature is regulated automatically within this range.
DEFGIf a temperature lower than +16 ° C is selected, then the respective tempera-
ture display lights up.
If a temperature higher than 29.5 ° C is selected, then the respective tempera-

lights up.
At both end positions, Climatronic runs at maximum cooling/heating output
and the temperature is automatically not regulated.
Controlling blower
The blower stage can be manually adapted to suit your particular needs.
If the blower speed is reduced to a minimum, Climatronic is switched off.
The set blower speed is displayed when the respective number of warning
lights illuminate in the control dial C

Automatic mode
The automatic mode is used in order to maintain a constant temperature and
to demist the windows in the interior of the car.
Automatic mode works in three modes - moderate, medium, and intensive.
Setting the individual operating modes » Operating instructions for Infotain-
ment , chapter Vehicle settings .
Climatronic is set to the medium setting at the factory.
After the automatic mode is switched on, Climatronic works in the last selec-
ted mode.
The currently selected mode is displayed in the Infotainment display.
Automatic mode can be switched off by pressing one of the buttons for the air
distribution or by increasing/decreasing the blower speed.
WARNING■ Do not switch off the Climatronic system for longer than necessary.■Switch on the Climatronic system as soon as the windows mist up.
Note
■When the intensive windshield defroster is switched on, the air flow to
the windows is switched on. The air flow to the windows will remain on
even after turning off the intense windshield defroster.■
Do not stick anything onto or cover the interior temperature sensor

120Using the system

CAUTION■The running auxiliary heater consumes fuel from the vehicle tank and auto-
matically controls the filling level. If only a low quantity of fuel is present in the
fuel tank, the auxiliary heating switches off.■
The exhaust pipe of the auxiliary heating, which is located on the underside
of the vehicle, must not be clogged and the exhaust flow must not be blocked.
■
If the auxiliary heating is running, the vehicle battery discharges. If the auxili-
ary heating and ventilation has been operated several times over a longer peri-
od, the vehicle must be driven a few kilometres in order to recharge the vehi-
cle battery.
■
The air inlet in front of the windscreen must be free (e.g. of ice, snow or
leaves) to ensure that the auxiliary heating operates properly.
Note
■ The auxiliary heating switches on the blower B » Fig. 125 on page 119 orC » Fig. 126 on page 119 only if it has achieved a coolant temperature of ap-
prox. 50 °C.■
At low outside temperatures, this can result in a formation of water vapour in
the area of the engine compartment. This is quite normal and is not an operat-
ing problem.
■
So that warm air can flow into the vehicle interior after switching on the aux-
iliary heating, you must maintain the comfort temperature normally selected
by you, leave the fan switched on and leave the air outlet vents in an open po-
sition. It is recommended to put the air flow in the position
or
.

The auxiliary heating can be switched on/off as follows.
Manually switching on Using the button on the operating part of the manual air conditioning/Cli-
matronic. The indicator light in the button illuminates » Fig. 127.
By using the radio remote control » page 123.
Manually switching off Using the button on the operating part of the manual air conditioning/Cli-
matronic. The indicator light in the button goes out » Fig. 127.
By using the radio remote control » page 123.
After switching the system off, the auxiliary heating will continue running a lit- tle while longer in order to burn the remaining fuel in the auxiliary heater.
After switching off the auxiliary heating, the coolant pump still runs for a short
period.
Switching on automatically
The auxiliary heater is switched on according to the Infotainment set-
tings » Infotainment manual , chapter Vehicle settings .
When automatic switching on is activated, the indicator light in the symbol
button lights up for about 10 seconds after the ignition is turned off.
Switching off automatically
Turning off the auxiliary heating occurs in the following cases.
› The switch-off time set in Infotainment has been achieved
» Operating in-
structions for Infotainment , chapter Vehicle settings .
› The fuel level has reached the reserve area (the warning icon
illuminates).
› The charge state of the vehicle battery has reduced too much

The transmitter and the battery are housed in the housing of the remote con-

When the battery is fully charged, the range of the remote control is a few
hundred metres. Obstacles between the radio remote control and the vehicle,
bad weather conditions and a weaker battery can clearly reduce the range.
To switch the auxiliary heating on or off, hold the remote control vertically,
with the aerial

» Fig. 128 pointing upwards. The antenna must not be cov-
ered with the fingers or the palm of the hand during this process.
The auxiliary heating can only be switched on/off safely using the radio re-
mote control, if the distance between the radio remote control and the vehicle
is at least 2 m.
After pressing the button, the warning light in the remote control gives the
user different kinds of feedback.
