Automatic transmission
fault indicator
If the symbol appears on the main instru-
ment panel, the system has detected a fault
in the automatic transmission or its control
module (see page 64).
This also means that the Limp-home mode
has been selected, to guard against further
damage being done to the transmission. In
this mode, the automatic transmission
starts in 4th gear, and gear changes (if nec-
essary) will have to be made manually.
It is not possible to select the SPORT or
WINTER mode when the Limp-home mode
is active.
You should have the automatic transmis-
sion checked as soon as possible by an
authorized Saab dealer.
The following gears will be engaged in the
respective selector positions when the auto-
matic transmission is in the Limp-home
mode:
Overheated transmission oilIf the transmission oil becomes overheated
while driving, the following message
appears on the SID: TRANSMISSION
OVERHEATING. In this event, stop the car
in a suitable place, switch off the engine,
open the hood and wait until the message
goes out. When driving subsequent to the
transmission oil overheating, select either
3rd gear or Drive, whichever will allow the
engine to run at 3,000 rpm and maintain the
speed of traffic or a safe speed.
The transmission oil can become very hot
when the car is driven with a heavy load; for
example, driving with a trailer on hilly roads
when the wrong gear has been selected,
resulting in many extra gear changes.
Select one of the positions 1, 2 or 3. A high
outside temperature or a defective oil cooler
can also cause the oil temperature to
increase. Contact an authorized Saab
dealer, see also page 173.
Driving in hilly country with a heavy
loadOverheating of the automatic-transmission
fluid can occur when the car is towing a
heavy load, such as a trailer in hilly country,
with the wrong gear selected, resulting in
abnormally frequent gear changing. To
avoid the transmission oil from overheating
always drive in Normal mode, then the
adaptive gear change pattern is active.
High ambient temperatures can also
increase the temperature of the transmis-
sion fluid or the oil cooler may be faulty. As
the transmission fluid temperature
increases, its useful service life is reduced.
Contact an authorized Saab dealer (see
also page 173).TowingTowing a car with automatic transmission,
see page 181. Position R D 3 2 1
Gear Reverse 4th 4th 3rd 3rd
NOTEIf the control module has actuated the
Limp-home function for the automatic
transmission, the car will remain in 4th
gear when D and 3 are selected, making
it very sluggish. To overcome this, move
the selector lever to position 1. The trans-
mission then starts in 3rd gear. When the
car is moving you can select position D
or 3.
WARNING
Remember to use engine-braking (selec-
tor position 1, 2, or 3) to spare the brakes
when you are driving on a long or steep
downhill slope.
Brake failure can result from overheated
brakes!

161 Starting and driving
If the gear selector lever is moved from position D to 1, a
change-down to 3rd gear will occur at about 110 mph (180 km/h).
A change-down to 2nd gear will occur at about 75 mph (120 km/h)
and to 1st gear at about 40 mph (65 km/h).
When position 1 is selected, all the other gears will be locked out.
Manual gear-changing is not recommended on slippery roads.
If one of the drive wheels spins excessively, the engine torque will
be reduced to avoid damaging the transmission.
Adaptive gear-change patternsAdaptive gear-change patterns are selected automatically depend-
ing on the engine load. This function applies in the Normal and Sport
modes.
The change occurs at a higher rotation speed and the gear remains
engaged for a longer period, if the control module senses that the
load does not drop. These change patterns avoid unnecessary gear
changes when, for example, driving on long inclines with a trailer,
and to prevent overheating of the transmission oil. This function cuts
in automatically if the oil becomes too hot, to protect the transmis-
sion from damage, and lowers the oil temperature.
The adaptive change pattern function is not activated at speeds over
93 mph (150 km/h). If a pattern is in operation when this speed is
exceeded, it will be maintained until the control module senses that
a more suitable one can be activated.
The adaptive gear-change pattern function is deselected when:
 Winter mode is selected.
 The engine is switched off.
 The load is reduced by so much that this function is no longer
required.
 “Automatic transmission fault indicator” appears on the
main instrument panel, see page 159.
NOTE Do not move the selector to position 3 at speeds in excess of
90 mph (150 km/h).
 Do not move the selector to position 2 at speeds in excess of
70 mph (110 km/h).

164 Starting and drivingDisengaging the system The system will be disengaged:
 When the brake or clutch pedal is
depressed.
 When the switch is moved to CANCEL.
 When the switch is moved to OFF.
 When the engine is switched off.
 When the selector lever is moved to posi-
tion N (cars with automatic transmission).
BrakingTo avoid overheating the brakes, (e.g. when
negotiating long descents with a drop of
several hundred feet), select a low gear to
use the braking effect of the engine. If the
car has automatic transmission, move the
selector lever to position 1 or 2.
When driving fast, you can help to prolong
the life of the brakes by thinking ahead and
braking harder for short periods, rather than
braking more moderately over long
stretches. Brake pad wear indicatorsThe outboard brake pads on the front
wheels incorporate pad-wear indicators.
When the lining is down to 3 mm, the pad
will produce a screeching, squealing or
scraping noise when the brakes are applied.
New pads should be installed without delay.
Brake pads should only be replaced by
an authorized Saab dealer.
To ensure optimum brake performance,
it is recommended that you use only
Saab original brake pads.

WARNING
 It is prudent to try your brakes from
time to time, especially when driving in
heavy rain, through water collected on
the road, in snow, on a wet road sur-
face or in salty slush. In such condi-
tions, the brakes may take longer than
normal to take effect. To rectify this,
touch the brake pedal periodically to
dry the brakes out.
 The same applies after the car has
been washed or when the weather is
very humid.
 Avoid parking the car with wet brakes.
Before parking, and if the traffic condi-
tions allow, brake quite heavily so that
the brake discs and pads warm up and
dry.
 The brakes are power assisted and it
should be kept in mind that the servo
unit only provides the power assis-
tance when the engine is running.
 The brake pressure required when the
engine is off,( e.g. when the car is
being towed) is roughly four times the
normal pedal force required. The
pedal also feels hard and unrespon-
sive.

175 Starting and driving
Recommendations for driving in
hilly terrainThe following time limits are based on the
capacity of the cooling system in warm
weather, i.e. approximately 86°F (30°C).
The following time limits are based on the
capacity of the cooling system in hot
weather, i.e. approximately 104°F (40°C).It is important to consider the following when
driving a car with automatic transmission up
long inclines.
Use Normal mode when driving with a cara-
van or trailer on hilly roads. The adaptive
gear change pattern function will prevent
the transmission overheating.
Rises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
The following may also occur:
 A/C compressor is switched off
 Gear change pattern is altered
 The CHECK message TRANSMISSION
OVERHEATING appears on the SID
If TRANSMISSION OVERHEATING
appears on the SID, stop the car as soon as
it is safe to do so and wait until the message
has been extinguished. When driving sub-
sequent to the transmission oil overheating,
select either 3rd gear or Drive, whichever
will allow the engine to run at 3,000 rpm and
maintain the speed of traffic or a safe speed;
see page 159.Do not drive continuously with the WINTER
mode selected in hilly country when you are
towing a trailer, as this will increase fuel con-
sumption and risk overheating the transmis-
sion.
Driving considerationsAlways take extra care when towing a
trailer, as the car’s handling will be different
and its braking effect reduced. The trailer’s
braking system and suspension also have a
considerable effect on these characteris-
tics, see also "Driving with a load" page
178.

WARNING
Remember to use engine-braking (selec-
tor position 1, 2, or 3) to spare the brakes
when you are driving on a long or steep
downhill slope.

MAXI fusesThe MAXI fuses are housed in the fuse box
under the hood. These fuses can be
checked in the same way as the other fuses.
The MAXI fuses are designed to protect the
car’s electrical system from being dam-
aged. Each MAXI fuse protects a number of
electrical circuits and functions and there-
fore has a higher rating (amperage) than the
standard fuses. No spare MAXI fuses are
supplied with the car.
DICE / TWICEDICE = Dashboard Integrated Central Elec-
tronics
TWICE = Theft-Warning Central Electronics
DICE and TWICE are electronic control
modules.
DICE controls, among other things:
 Front lights and interior lighting.
 Instrument illumination.
 Intermittent wiper operation.
 Electric heating of rear window and door
mirrors.
TWICE controls, among other things:
 Central locking.
 Car alarm (Anti-theft system).
 Engine immobilizer.
 Auto checking of lights.
 Electric heating of rear seat.
 Safety belt reminder.
 Electrically adjustable passenger seat.The DICE and TWICE control modules are
linked to a data bus, which is basically an
information carrier that allows information to
be exchanged between all the control mod-
ules and components connected to the bus.
If a fault occurs in any of these components,
diagnostic faults codes are set in the rele-
vant control module, which enhances fault
diagnosis at the Saab dealer.
The scan tool connector for fault diagnosis
is located under the instrument panel on the
driver’s side.
NOTEIf a MAXI fuse blows, it means that there
is a major fault in the electrical system.
Have the car checked without delay by an
authorized Saab dealer.
