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.■

The heating and air conditioning ventilate and heat the vehicle interior. The air
conditioning system also cools and dehumidifies the vehicle interior.
The heating effect is dependent upon the coolant temperature, thus full heat
output only occurs when the engine has reached its operating temperature.
The cooling system operates only if the following conditions are met. The cooling system is switched on.
The engine is running.
The outside temperature is above approx. +2 °C.
The blower is switched on.
If the cooling system is switched on, the temperature and air humidity drops in
the vehicle. The cooling system prevents the windows from misting up during
the cold season of the year.
It is possible to briefly activate recirculated air mode to enhance the cooling
effect » page 117 .
WARNING■
For your own safety and that of other road users, ensure that all the win-
dows are free of ice, snow and misting.■
The blower should always be on to prevent the windows from misting up.
WARNING (Continued)■ Under certain circumstances, air at a temperature of about 5 °C can flow
out of the vents when the cooling system is switched on.■
To reduce health risks (e.g. common colds), the following instructions for
the use of the cooling system are to be observed. ■The difference between the indoor temperature and the outdoor air
temperature should not be greater than about 5 ° C.
■ The cooling system is to be turned off about 10 minutes before the end
of the journey.
■ Once a year, a disinfection of the air conditioner or the Climatronic is to
be carried out by a specialist company.
CAUTION
■ The air inlet in front of the windscreen must be free of e.g. ice, snow or
leaves to ensure that the heating and cooling system operates properly.■
After switching on the cooling Condensation from the evaporator of the air
conditioning may drip down and form a puddle below the vehicle. This is not a
leak!
■
If the coolant temperature is too high, the cooling system is switched off to
ensure that the engine cools down.
Note
The used air streams out through the vents in the luggage compartment.

Air vents at the rear
Read and observe
and on page 116 first.
Warmed, not warmed fresh or cooled air will flow out of the opened air outlet
vents according to the setting of the control and the outside atmospheric con-
ditions.
The direction of airflow can be adjusted using the air outlet vents 3,

To ensure that the heating and air conditioning systems are able to work prop-
erly, do not cover the air outlet vents.
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.
Heating and air conditioning (manual air conditioning)
To switch on the recirculated air mode, press symbol button
. The warning
light below the button lights up.
To switch off the recirculated air mode, press symbol button

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
