Heating, ventilation and air conditioning (Electronic Climate Control)
Automatic setting Additional information
• The air conditioning system will function
best if it is always left on.
• 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 km/h).
• The air conditioning system functions only
at temperatures above 32° F (0° C).
• RECIRCULATION: When Recirculation
is activated, very little air is drawn into the
passenger compartment from the outside.
Use this function if the outside air is
contaminated with exhaust gases, smoke,
etc or to heat/cool the car quickly. If your
windows begin to fog or mist, check that the
recirculation function is NOT engaged.
NOTE: To help maintain stable passenger
compartment temperature when driving
with the convertible top down, or with the
windows open, adjust blower speed and the
temperature manually.
The air conditioning switches off auto-
matically when the convertible top is
down. The temperature must then be
adjusted 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 and open
the outer vents.
• The panel vents may emit some condensa-
tion 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" or "Defrost/floor" and the fan
speed to mid-range. Also shut the center air
vents.
Faults in the ECC system
The RECIRCULATION ON 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.

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 even if the AC OFF button is
depressed and the blower will run at its
maximum speed. When the windows have
cleared, set the function selector in the AUT
position.
Set the function selector and blower control to
AUT and select the desired temperature. If the
driver's side temperature selector is set to
either the max heating or max cooling
position, the blower will run at its maximum
speed.
