71 Instruments and controls
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 73 and 74).
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.

To increase the fan speed in steps.
If, after being off, the ignition is switched on but the
engine is not started, the fan will run at low speed
until the engine is running.
To decrease the fan speed in steps.
If the fan is set to 0, the A/C compressor will cut out
and ECON will appear on the display.
If, after being off, the ignition is switched on but the
engine is not started, the fan will run at low speed
until the engine is running.

Starting 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
and then save the setting by pressing
and .

74 Instruments and controlsProgramming IIIt is also possible to customize the ACC system, e.g. to adapt to
driving and weather conditions.
To program a function or to cancel a programmed function, press
and hold in the relevant button until the corresponding symbol has
flashed four times on the display and a chime has sounded.
Make sure the ignition is ON.
Example: To have the ACC system switch the heating for the rear
window and door mirrors ON/OFF automatically, press and hold in
until the symbol has flashed four times on the display and a
chime has sounded. Function Operation in AUTO mode

The A/C compressor will not
cut in unless the outdoor
temperature is above 55
°F
(+13°C).
–This function saves fuel by
delaying the cutting-in 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’ misting 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”. A range of additional functions can be reprogrammed in
the ACC system, although this can only be done by an
authorized Saab dealer, see page 237. Calibration
If the battery has been disconnected or has run flat, 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 73.
 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 73
and 74, 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 run flat, the ACC
system will need to be recalibrated. See ”Calibration” above.

118 Interior equipment and trunkTrunk pass-through hatch A trunk pass-through hatch is incorporated in the rear-seat backrest
to enable long, narrow items to be carried inside the car.
Items should not weigh more than 33 lbs. (15 kg) nor be more than
2 yards (2 metres) in length. See the label on the hatch.
1 Fold down the armrest.
2 Raise the hatch by lifting the handle.
Before loading or unloading long items, switch off the engine and
apply the handbrake. This averts the danger of the car moving off
suddenly if a long item were to knock the gear or selector lever into
gear. Tie DownsFour tie downs for securing the load are fitted inside the trunk. Place
the load as far in as possible.
WARNING
 Anchor the load securely (e.g. using middle safety belt) to
avoid danger of injury resulting from displacement of load on
hard braking.
 Do not exceed the load capacity of the car, as this will alter its
handling characteristics (see page 226).
