6Display and controlsThe system is always at operational readiness, except 
when manually switched off.
The automatic climate control only operates with the 
engine running.
The temperature selector should be left at the desired 
temperature setting. The temperature selected is 
reached as quickly as possible.
The system will not heat or cool any quicker by setting 
a higher or lower temperature.
The automatic climate control removes considerable 
moisture from the air during operation in the cooling 
mode. It is normal for water to drip on the ground 
through ducts in the underbody.
The desired interior temperature can be selected 
separately for the left and right side of the passenger 
compartment.

the defroster as soon as the window is clear.
The defroster is automatically turned off after a 
maximum of 12 minutes of operation.
If several power consumers are turned on 
simultaneously, or the battery is only partially charged, 
it is possible that the defroster will automatically turn 
itself off. When this happens, the indicator lamp inside 
the switch starts blinking.
As soon as the battery has sufficient voltage, the 
defroster automatically turns itself back on.Air distribution

This mode can be selected to temporarily reduce the 
entry of annoying odors or dust into the vehicle’s 
interior.
Outside air is not supplied to the car’s interior.
To select, press O button.
To c a nc el,   pr ess  O button again.
The system will automatically switch from recirculated 
air to fresh air
•after approximately 5 minutes at outside 
temperatures below approximately 40
°F (5
°C),
•after approximately 30 minutes, at outside 
temperatures above approximately 40
°F (5
°C),
•after approximately 5 minutes, if button S is 
pressed.
If the windows should fog up from the inside, switch 
from recirculated air back to fresh air.
At high outside temperatures, the system automatically 
engages the recirculated air mode thereby increasing 
the cooling capacity performance, switching to partially 
fresh air within 20 minutes.Dust filter
Nearly all dust particles and pollen are filtered out 
before outside air enters the passenger compartment 
through the air distribution system.
Notes:
Do not obstruct the air flow by placing objects on the air 
flow through exhaust slots below the rear window.
Also keep the air intake grille in front of windshield free 
of snow and debris.

when windows fog up on the inside, or if the passenger 
compartment needs to be quickly heated or cooled 
down.Residual engine heat utilization

space. When storing heat sensitive objects in the 
compartment, close the air outlet while heating the 
passenger compartment.
Also, do not obstruct the air outlet.
