DESCRIPTION

The special button (ice symbol) on the climate control system control unit switches on the air cooling and dehumidification circuit, activating the air conditioning compressor.

The above button enables the operation of the air cooling circuit, but the actual compressor activation is also dependent upon the activation of:

- the linear sensor, located on the coolant circuit that stops air conditioner activation if coolant pressure is too low or high;

- the Powertrain Control Module that excludes compressor operation in accordance with engine management mode; e.g. in the case of high engine temperatures or high engine load (sudden acceleration);

The button also only sends the control signal if the control knob for the different fan speeds is in a position other than "0".
