1997 Volvo 850
Set the function selector to
and move the blower control to the position AUT (as far to the left as
possible). The A/C system will be on at this time regardless of the A/C button's position and the blower
will run at its maximum speed. When the windows have cleared, set the function selector in the AUT
position.
Additional information
● The air conditioning system will function best if used regularly (at least once a month).
● Always keep the air intake grille at the base of the windshield under the rear edge of the hood free of
snow.
● Water under the vehicle in hot weather can be the result of condensation from the air conditioning
system and is quite normal.
● The air conditioning is disengaged when the blower is set at 0 and the speed of the vehicle is less than
20 mph (30 kn/h).
● The air conditioning system functions only at temperatures above 32° F (0° C).
● Recirculation (REC): Choose this position if the outside air is contaminated with exhaust gases,
smoke, etc. or to heat/cool the car quickly. In this position, very little air is drawn into the passenger
compartment from the outside. Do not leave the system in this mode for more than 10-15 minutes since
the air inside the car will become stale and condensation will form on the windows.
NOTE: To help maintain stable passenger compartment temperature when driving with the sun roof or
windows open, place the blower control in position "0" and adjust the desired temperature manually.
● If the panel vents are open, a certain amount of air will always flow through, regardless of the position
the function dial is in. To increase the flow of air to either the floor or the windows, close the panel
vents. The outer vents can be opened to avoid mist on the side windows.
● The panel vents may emit some condensation when the air conditioning is initially switched on and is
quite normal.
This may occur if the ambient temperature and humidity are high.
● The sunlight sensor (located at the top center of the dashboard) should not be covered in any way as
this could cause incorrect information to be sent to the ECC system.
● The air conditioning is momentarily disengaged during full-throttle acceleration.
Difficult weather conditions
When driving in very humid conditions, heavy rain, sleet, etc., it may be better to use the manual rather
