157 Starting and driving
Automatic transmission
The electronic control module for the auto-
matic transmission receives information on
engine torque and road speed, and also
controls the hydraulic pressure in the trans-
mission to ensure that gear changing is as
smooth as possible.
The position of the selector lever is shown
by the symbols adjacent to the lever and
also by an indicator on the main instrument
panel.
The ignition key can only be removed when
the selector lever is in the P position. When the car is stationary, the engine must
be at idling speed when the selector lever is
moved.
You must have your foot on the brake
pedal to move the lever out of park.
If the accelerator is depressed while the
lever is moved, this will result in abnormal
wear in the transmission.
WARNING
Make it a habit to keep your foot on the
brake when selecting a drive position,
to prevent the car from creeping for-
ward (or backward if reverse is
selected).
The car must be at a standstill before
P, R or N is selected. You have to have
your foot on the brake pedal to move
the lever out of P. If the car is still
moving when a drive position is subse-
quently selected, this could cause a
crash or damage the automatic trans-
mission.
Never park the car with the selector
lever in a drive position, even if the
parking brake is on.
Always select "P" position and apply
the parking brake when leaving the
vehicle unattended.
NOTEAfter selecting a drive position, pause to
allow the gear to engage before you
accelerate.

159 Starting and driving
Park Brake Shift lockThe transmission has a security function
known as Park Brake Shift Lock. To move
the gear selector out of the P position, the
brake pedal must be depressed at the same
time as the gear selector catch (detente) is
pressed in.
Shift Lock override1 Apply the parking brake
2 Make sure the key is in position ON
3 Use a small tool such as a screwdriver
and push the lever (see picture) down-
wards so that the detent button can be
pressed approx. 10 mm
4 Move the selector out of position P to N
5 Remove the tool
6 Release the parking brake if the car is to
be moved immediately; otherwise keep
it applied
Check fuse No. 1 (see page 218). If the fuse
is OK, check the battery regarding the volt-
age.
If the problem was cured by changing the
fuse or battery, you do not have to contact a
Saab dealer.
If the fuse blows again as soon as the Shift
Lock feature is activated you should contact
your Saab dealer.
Automatic transmission,
fault indicator
If ”Automatic transmission, fault indicator”
light appears on the main instrument panel,
the system has detected a fault in the auto-
matic transmission or its control module
(see page 55).
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 5th 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:
NOTEDue to electrical problems it may not be
possible to move the selector out of the
park position, even if the ignition is ON. If
for some reason the selector has to be
moved out of the park position (i.e. to tow
the car a short distance) do as described
below.

160 Starting and driving
Overheated transmission fluid If the automatic-transmission fluid should
overheat, the following message will appear
on the SID:
”TRANSMISSION OVERHEATING”. If this
happens, stop the car and wait for the mes-
sage to be extinguished. Continue driving in
a locked gear that produces an engine
speed of about 3,000 rpm.
Overheating of the automatic-transmission
fluid can occur when the car is towing a
heavy load, such as a camping trailer in hilly
country, with the wrong gear selected,
resulting in abnormally frequent gear
changing. Try selecting position L, 3 or 4.
High ambient temperatures can also
increase the temperature of the transmis-
sion fluid or the oil cooler may be faulty.
Contact an authorized Saab dealer (see
also page 173).
Driving on hilly roads with a heavy
loadThe transmission fluid can overheat when
the gearbox is strained, for example, when
driving with a trailer on hilly roads with the
wrong gear is selected, resulting in many
extra gear changes. To avoid the transmis-
sion fluid overheating, always drive in
Normal mode. The adaptive gear change
patterns are then active.
High air temperatures or a faulty oil cooler
can also cause the transmission fluid to
overheat. Overheating reduces the service
life of the fluid. Contact an authorized Saab
dealer (see also page 173). Towing Towing of cars with automatic transmission,
see page 180.
NOTEIf the control module has actuated the
Limp-home function for the automatic
transmission, the car will remain in 5th
gear when D is selected, making it very
sluggish. To overcome this, move the
selector lever to position L.
WARNING
Remember to use engine-braking (selec-
tor position L, 3, or 4) 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
Selector positions
P
To shift out of the P position you must
depress the brake pedal and the ignition
must be ON.
The parking position (P) must only be selected
when the car is at a complete standstill. The
selector lever is locked and the transmission is
mechanically immobilized. Always apply the
parking brake after parking the car.
The engine can be started. The key can be
removed.
R
The reverse (R) position must only be selected
when the car is at a complete standstill. The
detent-release button must be pressed before
the selector lever can be moved to R. Wait until
reverse gear has engaged (car starts to creep)
before touching the accelerator.
N
In the Neutral position (N), the transmission is
disengaged from the engine. The engine can be
started, but first ensure that the parking brake is
on, to prevent the car from moving off unexpect-
edly.
To prevent the engine and transmission from
becoming hotter than necessary, select N for
stops other than brief ones, e.g. if stuck in a traf-
fic jam.
The normal drive position (D) is recommended
for waiting at traffic lights.
D
The Drive position (D) is the position for normal
motoring. Gear changes between 1st and 5th
will take place automatically, the timing of which
is determined by the throttle (accelerator) posi-
tion and the speed of the car.
After moving the selector lever to D, pause to
give the gear time to engage (car starts to pull).
4
In position 4, 5th gear is locked out. The car will
start in 1st gear and normal gear changing (up
and down) will take place automatically between
gears 1, 2, 3 and 4.
Moving the selector lever from D to 4 will effect
a change-down to 4th gear, which will give better
engine-braking.
Do not move the selector to position 4 at speeds
in excess of 90 mph (150 km/h).
3
Position 3 is recommended in hilly country as it
provides effective engine-braking. Normal gear
changing (up and down) between 1st and 3rd
gear will take place automatically. Fourth and
5th gears are locked out.
Do not move the selector to position 3 at speeds
in excess of 70 mph (110 km/h).

164 Starting and drivingCruise controlFor safety reasons (brake system func-
tion) the brakes must be applied once,
when the engine has started, before the
cruise control system can be activated.
The system is operated by means of the
controls on the stalk switch:
ON/OFF (switch on/off).
RESUME/– (Resume preset speed).
SET/+ (to set the desired speed).
CANCEL (Cancel operation of system,
e.g. to reduce speed temporarily).
When the system is ON, the CRUISE indi-
cator light will appear on the main instru-
ment panel and will be extinguished when
the system is switched OFF. If CANCEL is
selected, CRUISE will flash once. To set the desired speed Move the switch to ON. Accelerate to the
desired speed (minimum speed: 25 mph
(40 km/h)) and press SET/+.
To increase the preset speed Accelerate to the desired speed and press
SET/+.
You can also increase the speed of the car
using the SET/+ button. Press it once to
increase the speed by 1 mph (1.6 km/h) or
hold it in and release when the desired
speed is reached. Temporary increase in speed Press the accelerator to override the preset
speed, e.g. for overtaking.
When you release the accelerator, the
system will revert to the preset speed. To cancel temporarily Move the control stalk to CANCEL
(spring-loaded position before OFF posi-
tion). This will disengage the system but the
preset speed will be retained in the system memory. (The memory is deleted when the
engine is switched off.)
To re-engage the system To revert to the preset speed, slide the
switch to RESUME/–. This will only operate
when the car’s speed is above 25 mph
(40 km/h). To reduce the preset speedThe cruise control system will always disen-
gage automatically the moment that either
the brake pedal or the clutch pedal is
depressed.
It is also possible to reduce the speed by
means of the RESUME/– button.
Sliding the button to RESUME/– once will
reduce the speed by 1 mph (1.6 km/h).
Holding the button in the RESUME/– posi-
tion will effect a gradual reduction in speed
until the button is released. Disengaging 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).
WARNING
Do not use the Cruise control system
on wet or icy roads, in dense traffic or
on winding roads.
Set the control to OFF when you do
not want to use the system, to prevent
the system being activated inadvert-
ently.

165 Starting and driving
BrakingTo avoid the brakes becoming overheated,
(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 fitted 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.
ABS brakesABS (antilock braking system) modulates
the brake pressure to the respective
wheels. Wheel sensors detect if a wheel is
about to lock, and the control module
reduces the pressure to that wheel and then
increases it once more until the tendency is
detected again.
The brake system is equipped with an Elec-
tronic Brake-force Distribution device
(EBD), which distributes the brake pressure
between the front and rear wheels, in such
a way as to achieve optimum braking perfor-
mance irrespective of the car’s speed and
load.
The ABS system has a built-in diagnostic
function which will switch on the Anti-lock
brake warning light if a fault is detected in
the system (see page 52).
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 on
tow) is roughly four times the normal
pedal force required. The pedal also
feels hard and unresponsive.
WARNING
The additional safety afforded by the
ABS system is not designed to allow
drivers to drive faster but to make
normal driving safer.
To stop as quickly as possible, without
loss of directional stability, whether
the road surface is dry, wet or slippery,
press the brake pedal down hard-
without letting up, declutching
simultaneously, and steer the car to
safety.

166 Starting and drivingThe ABS system will not reduce the braking
distance on loose gravel or on snow or ice
but, because the wheels cannot lock up,
some steering control is retained.
When the ABS system is working, i.e. mod-
ulation of the brake pressure is in progress,
the brake pedal will pulsate and a ticking
noise will be heard. All this is perfectly nor-
mal.
Press the pedal down hard (you cannot
press too hard) and steer the car to safety.
Do not release the brake pedal before the
car has come to a halt or the danger is
past!
That is critical.
If the road is slippery, the ABS system will
operate even when only light pressure is
applied to the pedal. This means that you
can brake gently to test the condition of the
road and adapt your driving accordingly.
It is well worth practicing the use of ABS
brakes on a skid pad or other suitable facil-
ity.

169 Starting and driving
ESP indicator lightThe indicator light in the rev counter
comes on for a short period of time when the
ESP system is operative.
Operation of the ESP indicates reduced
cohesion between the tires and the road,
and that extra care should be taken by the
driver.Turning ESP offThe system can be turned off manually with
the ESP button, whereupon the light
on the main instrument panel will come on.
The ESP system cannot be switched off if
the car is travelling faster than 35 mph
(60 km/h).
The ESP is always operative during brak-
ing, even if it has been switched off manu-
ally.
WARNING
When driving normally, ESP will help to
improve the stability of the car. This does
not mean that car can be driven faster.
The same care and prudence as normally
applied should be displayed on cornering
and when driving on slippery roads.
NOTESuspension modifications, such as
changing the type of wheels, dampers or
springs, can affect the function of the ESP
system.
Always consult a Saab dealer before
changing any suspension components.

171 Starting and driving
Driving in a low gear results in higher fuel
consumption than in a high gear because
of the higher engine speed for a given
road speed. Always change up to a higher
gear as soon as traffic conditions allow
and use the highest gear as much as pos-
sible.
Check the air pressure in the tires once a
month. Incorrect pressures increase tire
wear. It is better to have slightly higher
pressure than lower.
Check fuel consumption regularly.
Increased consumption can indicate that
something is wrong and that the car
needs to be checked by an authorized
Saab dealer.
Practical trials on the roads have demon-
strated that substantial savings in fuel con-
sumption can be made if the above advice
is heeded.Road conditions Wet roads increase fuel consumption, as do
unpaved roads and driving in hilly country
(the amount of fuel saved driving downhill is
less than the additional amount required to
climb the hill).
Engine block heater (standard
equipment in Canada, accessory in
U.S.)The following are just some of the benefits
to the car and the environment of using an
engine block heater:
Lower fuel consumption.
Reduced wear on the engine.
Inside of car warms up faster.
Exhaust emissions substantially reduced
over short runs.
The engine heater is effective at outside
temperatures up to +15-20°C. The warmer
it is outside, the shorter the time the engine
heater needs to be connected. Longer than
1.5 hours is unnecessary.
If the car is equipped with a removable,
electrical cabin heater that is not in use, this
should be stored in the luggage compart-
ment.
Driving in cold weatherBefore starting a journey in cold weather
you should check the following:
That the wiper blades have not become
frozen to the windshield/glass.
Brush any snow away from the air intake
for the heater system (opening between
hood and windshield).
It may be advisable to lubricate the
door-lock cylinder (use molybdenum
disulphide, MoS
2) to prevent its freezing.
If the lock has frozen, take care not to
break the key (or use the remote control)
– heat it first or spray it with de-icer.
Periodically during the winter, add gaso-
line anti-freeze to the fuel to dispel any
condensation in the fuel tank which could
freeze and cause problems in the system.
Keep the tank well filled to reduce the risk
of condensation forming.
If the car is parked outside in freezing
weather, fuel additives (gasoline
anti-freeze) will not do any good as it
cannot remove water that has already fro-
zen. Park the car in a warm place so that
any ice that may have built up melts, then
add gasoline anti-freeze when filling up
the tank. Condensation is caused by
changes in the outdoor temperature or by
the car being parked alternately in a
garage and outside.
It is particularly important when the roads
are slippery that the brakes and tires be in
good condition.
WARNING
Never switch the engine off while driving
as the effect of the brakes and power
steering will be greatly reduced.

174 Starting and drivingTrailer weightMaximum recommended trailer weights for
different gradients, with a view to comfort
and drivability for manual and automatic
cars, are shown on the drawing.
Make sure you are familiar with the law
regarding speed limits for towing, maxi-
mum trailer weights, trailer-braking
requirements, and also any special
driving-licence provisions
(see also page 249).
The specified trailer weights and gradients
assume that the journey starts at the hill and
therefore apply only to short periods. Recommendations for driving in hilly
terrain
The 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).
WARNING
When towing a trailer, do not attempt to
negotiate a hill having a gradient in
excess of 15%. The weight distribution
over the front wheels of the car will be
insufficient to prevent wheelspin, making
further progress impossible.
In addition, the parking brake may not
always be able to hold the car and trailer
securely, with the result that the wheels
can start to slide downhill.
