Air conditioner  
Description  
If you notice, for instance, that the seat or  
rear window heating (if fitted) is not work-  
ing, it may have been temporarily switched  
off by the energy management system.  
These systems will be available again as  
soon as sufficient electrical power is availa-  
ble.  
Depending on your vehicle’s equipment, one of  
the following options is available:  
A 2-zone deluxe automatic air conditioner  
which can be used to adjust the temperature  
and air distribution at the front left and right  
individually  
Information on the air conditioner for the  
European Union  
A 3-zone deluxe automatic air conditioner  
which can be used to adjust the temperature,  
air distribution and blower speed at the front  
left and right and the temperature at the rear  
individually.  
The air conditioner contains the fluorinated  
greenhouse gas known as R-1234yf.

A 4-zone deluxe automatic air conditioner  
which can be used to adjust the temperature,  
air distribution and blower speed settings for  
all the seats individually  
global warming potential (GWP) is provided on a  
sticker in the engine compartment.  
Controls  
The air conditioner heats, cools, dehumidifies  
and filters the air inside the vehicle. It operates  
most effectively with the windows and the sun-  
roof (if fitted) closed. If the vehicle has been  
standing in the sun, it may cool down faster if  
you open the windows briefly to let the hot air es-  
cape.  
The deluxe automatic air conditioner will main-  
tain the desired temperature at a constant level.  
When the heater is on, the blower normally only  
switches to a higher speed once the coolant has  
warmed up sufficiently (this does not apply to  
the defrost setting).  
Fig. 87 Centre console: Lower display and row of buttons  
Adjustments can be made using the two displays,  
the row of buttons in the centre console and the  
control console in the rear cabin (depending on  
the equipment in your vehicle). For information  
on how to use the touch displays, refer to

Enhanced air filter with activated carbon  
When the blower is switched on, the filter re-  
duces the concentration of fine particulate mat-  
ter and pollen and neutralises odours in the vehi-  
cle interior.  
All of the air conditioner settings are available  
from the front seats; from the rear seats, only  
certain functions are available.
