Switching the cooling function 
on and off
The cooling function cools and 
dehumidifies the incoming air 
before reheating it as required, 
according to the temperature set-
ting. This function is only available while the 
engine is running.
The cooling function helps prevent condensa-
tion on the windows or removes 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.
Maximum cooling
Maximum cooling is achieved most 
quickly at outside temperatures 
above 32
7/0 6 and when the 
engine is running.
The automatic climate control goes into recir-
culated-air mode at the lowest temperature. Air 
flows at maximum rate from the vents for the 
upper body area. You should therefore open the 
vents for maximum cooling.
AUTO program
The AUTO program automatically adjusts the 
air distribution to the windshield and side win-
dows, towards the upper body area, and into the 
footwell and knee area.
The air flow rate and air distribution, in addition 
to your temperature specifications, will be 
adapted to outside influences as a result of sea-
sonal changes, e.g. sunlight or window conden-
sation.
The cooling is switched on automatically with 
the AUTO program.
Switching on/off
 Press the button.
Manual air distribution and air flow rate are acti-
vated when the AUTO program is deactivated.
AUTO program climate level
The climate levels can be used to vary the inten-
sity when the AUTO program is switched on. 
For example, air flow is adjusted automatically 
to optimize climate control.
When the AUTO program is 
switched on, you can select the cli-
mate level of the AUTO program 
using the buttons for controlling the manual air 
flow rate.
The selected climate level is displayed by 
an LED.
Convertible program
When the hardtop is open, the convertible pro-
gram is activated as well. In the convertible pro-
gram, the automatic climate control is opti-
mized for driving with the hardtop open. In 
addition, the air flow rate is increased as vehicle 
speed increases.
The effectiveness of the convertible pro-
gram can be enhanced considerably by 
installing the wind deflector.

Adjusting air flow rate manually
Press the left side of the button to 
reduce air flow. Press the right side 
of the button to increase it.
The air flow rate may be reduced to save battery 
power. The display remains the same.
Switching the system on/off
With the blower at its lowest setting, press the 
left side of the button to switch off the auto-
matic climate control. All displays are cleared 
except for the rear window defroster if it is 
switched on.
Press any button except the rear window 
defroster to reactivate the automatic climate 
control.
Residual heat
The heat stored in the engine is used to heat the 
passenger compartment, e.g. while stopped at 
a school to pick up a child.
