Mercedes-Benz E 320 1994 Owner's Manual page 25

Dust Filter
Dust particles (down to a certain size) and pollen
are filtered out before outside air enters the passen­
ger compartment through the air distribution system.
Important!
This vehicle is equipped with an air conditioner
system that uses HFC-134a (ozone-friendly hydro-
fluorocarbon) as a refrigerant.
Repairs should always be performed by a qualified
technician, and refrigerant should be collected in a
recovery system for recycling.
Temperature Selection
The desired interior temperature can be se­
lected by rotating the temperature selector.
The selected temperature is reached as
quickly as possible and maintained. A basic
setting of 7 2 °F (22°C) is recommended.
Air Recirculation
Press symbol side of switch = the air re­
■
circulation mode is engaged. The indicator
lamp in the switch lights up.
This mode can be selected to prevent an­
noying odors or dust from entering the car's interior.
At high outside temperatures, the system auto­
matically engages the air recirculation mode, there­
by increasing the cooling capacity performance.
The recirculated air mode will be automatically
switched off after approximately 30 minutes of
operation at outside temperatures above approxi­
mately 4 5 ° F (7°C) and after approximately
5 minutes at outside temperatures below approxi­
mately 4 5 °F (7°C).
If the windows begin to fog up from the inside,
switch from recirculated air back to fresh air by
pressing the lower half of the air recirculation switch
(the indicator lamp in the switch goes out).
Note:
It is not possible to switch to recirculated air if
button Q or 0 is depressed.
