71 Instruments and controls
The system has five sensors:
 Outdoor temperature sensor.
 Interior temperature sensor.
 Sun sensor (mounted on top of the
fascia).
 Two blended-air temperature sensors
(mounted inside the front floor vents).
Caution If anything is placed over the sun
sensor, the ACC system will not function
properly.
Panel vents The panel vents swivel universally, so that
air can be directed as desired. In winter, for
instance, the outer vents can be directed
onto the door windows for enhanced
demisting.
The flow of air through the panel vents can
be controlled individually for each vent by
means of the adjacent control. The climate
control system works best if the panel vents
are open. If you find the air cold or that it is
draughty, start by directing the air away
from the body. If the center vent is aimed up,
it will cool the interior temperature sensor
and you may need to adjust ACC up or
down, depending upon temperature
desired.

Temperature control The cabin is divided into two temperature
zones:
 The driver’s zone.
 The passenger zone (front and rear
seats).
The desired temperature can be set
between 58 and 82°F (15 and 27°C). In
addition, there are also HI and LO settings
(see below). The HI and LO settings for the
passenger zone can only be selected if they
are also selected for the driver’s zone.
The displayed temperature is not the abso-
lute temperature but corresponds to the
comfort level normally experienced at that
temperature after allowance has been
made for the air flow, relative humidity, solar
radiation, etc., currently prevailing inside
the car.
 The most usual temperature setting is
64-76°F (18-24°C), depending on per-
sonal preference and what clothing is
worn.
 It is recommended that changes in the
temperature setting be made in steps of
2°F (1°C).
 Once the desired climate has been
achieved, the rear center vents can be
closed to prevent warm air being distrib-
uted at face height.Settings when HI selected:
 Maximum heat.
 Air distribution to windshield and floor.
 Recirculation OFF (even if manually
selected before).
 Fan: high speed.
 Settings shown on ACC display.
Settings when LO selected:

The rear-window and door-mirror heating is
controlled manually. Switch off the heating as soon as the rear window
is clear, to avoid imposing a heavy load on the bat-
tery longer than necessary. Note, however, that the
heating will go off automatically after 5-10 minutes
(depending on the outdoor temperature) or sooner
if the voltage in the electrical system falls below
10 V
.
The ACC system can be programmed to switch on
the heating automatically when the outdoor temper-
ature is below 41°F (+5°C) and the temperature
inside the car is below 50°F (+10°C) (see ”Program-
ming I and II”, on pages 76 and 77).
Recirculation is selected automatically for effective
cooling, but it can also be switched on/off manually.
Although recirculation does not substantially affect
the air quality, it is useful to prevent unpleasant
smells or fumes being drawn into the car from
outside.

76 Instruments and controlsStarting in cold weather
To start with, the system will automatically select the defroster set-
ting, maximum heat and low fan speed.
As the engine warms up, air will also be distributed through the floor
vents and the fan speed will be increased.
As the temperature inside the car nears the selected value, both the
fan speed and the heat will be decreased to a level determined by
the system.
Starting in hot weather
The system will automatically distribute air through the panel vents
at high fan speed and will switch on the A/C compressor (unless the
ECON switch has been pressed).
If the outdoor temperature is above 86
°F (30°C), the system might
select recirculation after approximately 45 seconds if this is required
in order to reach the desired temperature.
As the temperature inside the car nears the selected value, the fan
speed will be decreased to a value determined by the system.
Programming IManual selections can be programmed into the ACC system so that
these will take effect when the car is started. Note that the ignition
must be switched off for at least ten minutes after programming for
the selections to be saved in the system’s memory.
1 Make sure the ignition is ON.
2 Select the desired settings.
3 Press and , simultaneously
(the display will flash to confirm that the settings have been
recorded).
Example: If you want air distribution through the panel vents when
you start the car, press

Programming IIIt is also possible to customize the ACC system, e.g. to adapt to
driving and weather conditions.
Function Operation in AUTO mode
after Programming II Standard operation
in AUTO mode
The A/C compressor will not
activate unless the outdoor
temperature is above 55
°F
(+13°C).
–This function saves fuel by
delaying the activation of the
A/C compressor. However,
in wet weather it is advisable
to have the A/C compressor
running when outdoor tem-
peratures are below
57°
(+14°C), as the A/C system
reduces the likelihood of the
windows’ fogging up.
A/C compressor cuts
in when outdoor tem-
perature is above 41
°F
(+5°C)
Recirculation will be
switched on if the speed of
the car is less than 6 mph (10
km/h) and will be switched off
when the speed has risen
above 20 mph (30 km/h), but
not if the ECON mode has
been programmed according
to ”Programming II”.
–This function is useful to
prevent fumes being drawn
into the car in traffic jams.
Recirculation is
switched on about
45 seconds after start-
ing if the outdoor tem-
perature is above 86
°F
(+30°C) and the
selected temperature
for the cabin is well
below the actual tem-
perature in both tem-
perature zones.
The heating will come on
about five seconds after the
engine has started if the out-
door temperature is below
41°F (+5°C).
–This function helps to pre-
vent ice or mist forming on
the rear window in cold,
damp weather. Fuel con-
sumption may increase
slightly.
Rear-window heating
can only be switched
on manually.

Once a function has been recorded under ”Programming II”, it will
remain in the system until you cancel the program.
AUTO will still show on the display after a function has been saved
in ”Programming II”.
Calibration If the battery has been disconnected or has died, the system will
need to be recalibrated.
To start the calibration procedure:
1 Start the engine.
2 Press and simultaneously.
Calibration takes about 30 seconds. During this time and for about
3 seconds after the operation has been completed, the number of
fault codes (if any) stored in the system will appear in the tempera-
ture display on the left. The fault codes themselves will be shown in
the temperature display on the right. Useful tips (Before driving the car to an authorized Saab dealer)
 If AUTO is not shown on the display, see ”Cancelling the pro-
grammed settings (I)” on page 76.
 If you suspect that the ACC system is not functioning properly,
cancel (delete) all programmed settings and then recalibrate the
system.
See ”Cancelling the programmed settings (I) and (II)”, pages 76
and 77, and ”Calibration” above.
Note that AUTO will show on the display even if you have com-
pleted Programming II, but that this does not apply to Program-
ming I.
 If the battery has been disconnected or has died, the ACC system
will need to be recalibrated. See ”Calibration” above. Function Text displayed on SID

Condensation When the A/C system is running, the intake
air is dehumidified, and the resultant con-
densation is drained off through two outlets
underneath the floor of the car, in the vicinity
of the front doors.
It is therefore perfectly normal for water to
be seen dripping from these outlets when
the car is parked. Greater amounts of con-
densation will result in warmer, more humid
ambient air.
Formation of ice and mist in
extremes of weather It is only in the most extreme conditions that
icing and misting of window glass are likely
to be a problem, e.g. in torrential rain or
severe cold coupled with high relative
humidity, or when passengers are perspir-
ing heavily or wearing wet clothes.
The following measures are recommended
if such problems should occur:
1 Select AUTO and 70
°F (21°C) for both
temperature zones.
2 Select Defroster.
If this is not enough...
3 Increase the fan speed.
If this is not enough...
4 Select a higher temperature.
The following measures are recommended
if the occupants feel that it is cold and drafty
in the car:
1 Make sure that all the air vents are fully
open, including the center rear vent.
If this is not enough...
2 Direct the air flow away from the body
(but not towards the interior temperature
sensor).
If this is not enough...
3 Raise the temperature setting a degree
or two. If this is not enough...
4 Lower the fan speed.
