compartment from 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
than the automatic setting to defrost the windows. Set the mode selector to "Defrost"
floor" and the fan speed to 3 or higher. Also shut the middle air vents.
Faults in the ECC system
The REC and AC OFF lights will flash for approximately 20 seconds if a fault is detected in the ECC
system.
If this flashing recurs the next time the system is switched on, the climate control unit should be checked
by an authorized Volvo retailer.
