A congenial climate
For almost all conditions, the AUTO pro-
gram 12 offers the optimal air distribution and 
air volume. Select an interior temperature you 
find pleasant.
The following section contains 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.< 
Automatic air distribution and supply 
The AUTO program adjusts the 
airflow and distribution patterns for 
you while also using your prese-
lected temperature setting as the basis for 
adjusting the interior climate to adapt to exter-
nal influences: summer, winter. 
The cooling is switched on automatically with 
the AUTO program.
Individual air distribution 
You can cancel the AUTO program 
by selecting specific air distribu-
tion patterns for your personal 
comfort, the automatic air supply 
remains in operation. You can 
direct air to flow onto the win-
dows  , toward the upper body  , and into 
the footwell  . You can reactivate the auto-
matic air distribution mode by selecting the 
AUTO button.
Adjusting temperature 
The figures in the display provide a 
general indication of interior tem-
perature. When you start the vehi-
cle, the AUTO program ensures 
that the selected temperature is 
achieved as quickly as possible. It 
then maintains this temperature, regardless of 
the season.
Air supply/blower 
You can vary the air supply by 
pressing the upper or lower button. 
This switches off the automatic 
program for the air supply, and the 
word AUTO goes out in the dis-
play. The automatic mode for air 
distribution remains in operation as before. You 
can reactivate the automatic air supply mode by 
selecting the AUTO button.
If you press the lower button when at the lowest 
blower speed, all displays go out: the blower, 
heating and air conditioner are switched off. 
The outside air supply is shut off. You can 
restart the automatic climate control by press-
ing any of its buttons.
Defrosting windows and removing 
condensation 
This program quickly removes ice 
and condensation from the wind-
shield and door windows. 
Air conditioner 
When the air conditioning is on, 
the air is cooled, dehumidified, 
and then reheated depending on 
the temperature setting. Depending on the 
weather, the windshield may fog over briefly 
when the engine is started. The air conditioner 
reduces the formation of condensation on the 
windows.
The air conditioner can only operate when the 
engine is running and is automatically switched 
on with the AUTO program.
Condensation forms in the air conditioner 
system during operation, and then exits 
under the vehicle. Traces of condensed water 
under the vehicle are therefore normal.< 
Outside air/AUC Automatic 
recirculated-air control/recirculated-
air mode 
You can respond to unpleasant 
odors or pollutants in the immedi-
ate environment by suspending 
the supply of outside air. The system then recir-
