The climate control system is adjusted manually.
CONTROLS fig. 78
A - Knob for operating the fan and switching the climate control system on and off.
The climate control system can only be switched on when the pointer on this knob
is at speed 1, 2, 3 or 4 
the led on
the knob will light up when the system is on.
Consequently, the climate control system cannot be switched on when the pointer
is at 0 
B - Recirculation slider, to cut out outside air.
IMPORTANT
This function is particularly useful when the outside air is heavily polluted (in a traffic jam, tunnel, etc.) and when running on dusty roads. You are advised against using this function for long periods, however, especially if there are a lot of people in the vehicle or on cold or rainy days since the windows could mist up effecting visibility and driving.
C- Air temperature knob (warm/cool air mixer).
D - Air distribution knob.
The system uses refrigerating fluid R134a which will not pollute the environment if it accidentally leaks.
Under no circumstances should fluid R12 be used as this is incompatible with the system’s component parts.
