Additional information and tips
●
The air conditioning compressor is engaged only if the temperature is above 46°F (+8°C).
●
In all three air conditioning positions the fan runs at speed 1 if the switch is at "O".
This is a safety measure to prevent formation of ice in the system.
●
When the outside air is contaminated with exhaust gases, smoke, etc. (as when driving through a
tunnel), move the lever to
for a few minutes. In this position very little air is drawn in to the passenger compartment from
outside. Do not,
however, leave the lever in this position for more than 10-15 minutes, since hardly any fresh air is being
supplied.
Regulate the temperature with the temperature control lever.
●
The air conditioning unit functions best if used regularly.
