maintain a comfortable in-car
temperature regardless of the outdoor
temperature.

Operating Tips
Recirculation: When the
outside air is contaminated
with exhaust gases, smoke
etc. (as when driving
through a tunnel) or to cool
the car quickly, push the
recirculation button. In this
position, no air is drawn into
the passenger compartment
from outside. However, do
not leave the system in this
mode for more than 10-15
minutes, since the air inside
the car will become stale
and the windows may fog.
Recirculation (and the
indicator light) will also
come on when the interior of
the car is hot and a low
temperature is selected with
the temperature dial. This
helps speed cooling of the
passenger compartment. It
will switch off automatically
after several minutes.
Difficult weather
conditions
When driving in very humid 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.

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. NOTE:
l Do not place any
objects over the
sensor in the
passenger side
speaker grille as
this will cause the
ECC system to
respond incorrectly
to ambient
conditions.
l 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.

conditioning
compressor only
engages at
temperatures above

base of the
windshield free of
