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 "0". 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.
Always keep the air inlet grill in front of the windshield clear of snow in winter.
