ECC system fault indication
If the light in the air conditioning push button begins to flash when the ignition is switched on, a simple
fault is indicated. The system will compensate by substituting a standard value stored in the memory.
System performance loss will be slight.
If the light continues to flash more than 20 seconds, a more serious fault is indicated. While the system
will again attempt to substitute a standard value, some reduction in system performance will become
apparent. Contact your authorized Volvo retailer for service.
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" or "Defrost/floor"
and the fan speed to 3 or higher. Also shut the middle air vents.
