Engine overheat protection (Air conditioning)

Engine overheat protection

If engine coolant temperature reaches 117.5°C (diesel models) or 118°C (petrol models), the ECM switches the air conditioning off to reduce the load on the engine (the indicator lamp in the air conditioning switch remains on). When engine coolant decreases to 115°C (diesel models) or 114°C (petrol models), the ECM switches air conditioning on again.

Fresh/Recirculated air selection

When recirculated air is selected, the amber indicator lamp in the switch illuminates and the recirculated air motor turns the control flap to open the recirculated air inlet and close the fresh air inlet. When fresh air is selected, the amber indicator lamp extinguishes and the recirculated air motor turns the control flap to open the fresh air inlet and close the recirculated air inlet.
