that freeze button was used to manually turn the A/C on and off.
that SSA unit is something really special. its the only car i have found with that unit, even it is was not delivered with that thing. it was used short time to reduce the emissions and the fuel consumption of a car by turning the engine off, e.g. while staying at a red traffic light or something. to start the engine again you only have to put the "gear-level" into first gear position and the engine will start automatically. very interesting while cruising in cities.
