Mercedes-Benz 260 E 124 1987 Owner's Manual page 25

Temperature Selection (°C)
The desired temperature can be adjusted by turning
the temperature selector. The selected temperature is
reached as quickly as possible and maintained. A
basic setting of 22°C (72°F) is recommended. To avoid
undesirable temperature fluctuations, a set temperature
should be readjusted in small increments.
To override the automatic climate control turn the tempe­
rature selector to either extreme end position " MIN" or
" MAX" .
" MIN" (detend) = peak cooling performance. The system
operates with recirculated air, without additional fresh air.
" MAX" (detent) = maximum heating performance.
If button £ 3 is pressed with the temperature selector in
the " MIN" or " MAX" position, it will run continuously at a
high speed.
Air Recirculation
I S Pressing the symbol-side of the air recirculation switch
i S causes air to be recirculated without additional fresh
* air and the red indicator lamp to light up. After a while
the air recirculation mode will switch off automatically,
including the indicator lamp.
The air recirculation mode can be used with high or low
outside temperatures, or to prevent dust or annoying
odors from entering the car's interior. If the windows
should fog up from the inside, the air recirculation switch
should be shut off. The red indicator lamp should then go
out.
Note:
The air recirculation mode will not come on if button
is pressed.
Function Setting

is shut off (to prevent entrance of odors, i.e. while driving
through tunnels, etc. or to prevent the entrance of water
from an automatic car wash). While driving use this set­
ting only temporarily.
