A congenial climate
For almost all conditions, the AUTO pro-
gram12 offers the optimum air distribution and 
air volume, refer to AUTO program below. You 
need only select an interior temperature 5 that 
you find pleasant.
The following sections contain more detailed 
information on the available setting options.
Your vehicle has been designed to auto-
matically select your personal climate-
control settings whenever you unlock the doors 
using your individually programmed remote 
control.<
AUTO program
The AUTO program handles the 
adjustment of air distribution to the 
windshield and side windows, in 
the direction of the upper body, and in the foot-
well. It also adapts your instructions for the air 
volume and temperature to outside influences 
throughout the year, e.g. solar radiation or win-
dow condensation.
The cooling function is switched on automati-
cally along with the AUTO program.
Manually switching air distribution 
on/off
You can direct air to flow onto the 
windows  , toward the upper 
body   and into the footwell  .
You can reactivate the automatic 
air distribution mode by selecting 
the AUTO button.
Temperature
Set the desired temperature.
The automatic climate control 
assures that this temperature is 
reached as quickly as possible any 
time of year, using maximum cool-
ing or heating capacity as needed, and then 
keeps this temperature constant.The highest setting produces the maximum 
heat output regardless of the outside tempera-
ture. The lowest setting activates maximum air 
conditioning.
When you change between different tem-
perature settings in rapid succession, the 
system does not have enough time to achieve 
the desired temperature.<
Manually adjusting air volume
By pressing the lower button, you 
can reduce the air volume. You can 
increase it by pressing the upper 
button.
You can reactivate the automatic 
air volume mode by pressing the AUTO button.
Switching system on/off
At the lowest fan speed, press the lower button 
to turn off the automatic climate control com-
pletely. All displays disappear.
Press any button to turn the automatic climate 
control back on again.
Defrosting windows and removing 
condensation
Quickly removes ice and conden-
sation from the windshield and 
front door windows.
Also switch on the cooling function.
Switching cooling function on/off
When the cooling function is on, 
the air is cooled, dehumidified, and 
then reheated depending on the 
temperature setting. This function is only avail-
able with the engine running.
The cooling function helps to prevent conden-
sation from forming on the windows or to 
remove it quickly.
Depending on the weather, the windshield may 
fog over briefly when the engine is started.
The cooling function is automatically switched 
on along with the AUTO program.
