161 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 overrideCheck fuse No. 1 (see page 229). 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.
If the fuse is OK, check the battery regarding
the voltage.

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
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 59).
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.
Stop the car in a safe place. Switch off then
restart the engine. If the fault is intermittent,
the transmission will operate as normal
despite the fault indicator being on. Have
the car checked at an authorized Saab
dealer.
It is not possible to select the SPORT,
WINTER or Sentronic mode when the
Limp-home mode is active.
Gear changes must be made manually.
The following gears will be engaged in the
respective selector positions when the auto-
matic transmission is in Limp-home mode:
NOTICEDue 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.

162 Starting and driving
Overheated transmission fluid If the automatic-transmission fluid should
overheat, the following message will appear
on the SID:
”Gearbox too hot. Make a safe stop.”. In this
event, stop the car in a suitable place,
switch off the engine and open the hood.
Wait for several minutes then turn on the
ignition to check that the message has gone
out. When driving subsequent to the trans-
mission fluid overheating, select a gear in
which the engine speed is 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. High ambient temperatures can
also increase the temperature of the trans-
mission fluid or the oil cooler may be faulty.
Contact an authorized Saab dealer (see
also page 178).
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. To avoid
the transmission 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 178). Towing Towing of cars with automatic transmission,
see page 188.
NOTICEIf 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.
Select position L to prevent unnecessary
wear on the transmission. The transmis-
sion then starts in 2nd gear. Once the car
is moving you can select position D.
When the indicator light is on, the car
must not be driven with a caravan or
trailer attached.
WARNING
Remember to use engine-braking (selec-
tor position D or L) to spare the brakes
when you are driving on a long or steep
downhill slope.
Brake failure can result from overheated
brakes!

163 Starting and driving
Descending hillsIf the speed of the car increases while
descending a steep hill, despite the acceler-
ator being released, the control module will
change down a gear when you brake. If you
desire more powerful engine braking, man-
ually select a lower gear.
Sentronic, manual modeMove the selector lever to the M position.
Select a higher gear by flicking the
right-hand paddle towards you. Select
a lower gear by flicking the left-hand paddle
towards you.
An example of when you may wish to make
manual gear changes is when overtaking, to
enable you to remain in a low gear for an
extended period of time.
Changes from 3rd to 4th and from 4th to 5th
can be made when the engine speed is
above roughly 2,000 rpm.
If you select a gear that is judged too high by
the system, the selected gear position will
be shown briefly on the main instrument
panel and then the gear that is actually
engaged.
If the road surface is slippery, you may wish
to pull off in 2nd or 3rd to reduce the risk of
wheel spin.
When descending hills you should select a
low gear to increase the braking effect of the
engine and thus spare the brakes.
Manual gear selections are shown on the
main instrument panel. The selector posi-
tion and the current gear are displayed.When the selector lever is in the M position,
as opposed to the D position, gas engines
are much more responsive to changes in
accelerator position. The accelerator has a
different feel.
When in manual mode, kick-down operates
for 4th and 5th gears (below 2,000 rpm).
Kick-down cannot be activated in 1st, 2nd or
3rd gears.
For optimum performance, gear changes
should be made before reaching 6,000 rpm.
To avoid damaging the engine and trans-
mission, the transmission will shift up a gear
if the engine is in danger of overrevving. You
may feel a slight jolt before this gear change
is effected.

169 Starting and driving

ABS brakes
ABS (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.
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.
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 (do not pump the
pedal), declutching simulta-
neously, and steer the car to safety.

175 Starting and driving
a major impact on fuel consumption after
the engine has started from cold. Thus, if the
car is mainly used for short journeys of
3–5 miles (5–8 km), the fuel consumption
will be 60–80 % higher than normal.Driving technique To obtain the best running economy, not
only regarding fuel consumption but gen-
eral wear also, regular service is required.
 High speed, unnecessary acceleration,
heavy braking and much low gear work all
gives rise to higher fuel consumption.
 Frequent gear changing in traffic, starting
in cold weather, the use of studded tires
and roof racks, and towing a trailer all
increase fuel consumption.
 Do not run the engine when the car is sta-
tionary.
If idling, it will take much longer before the
engine becomes hot. Engine wear is
greatest during this warming-up phase.
Therefore drive away as soon as possible
after the engine is started and avoid high
revving. 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).
WARNING
Never switch the engine off while driving
as the effect of the brakes and power
steering will be greatly reduced.

178 Starting and driving2 Wait until the needle has dropped back
to indicate normal temperature (roughly
midway, in the white zone) before stop-
ping the engine. If the coolant needs top-
ping up, unscrew the cap on expansion
tank carefully.
Top up, as necessary, ideally with a
50/50 mixture of Saab-approved coolant
and water. If only water is available, use
that, but remember to have the coolant
mixture checked as soon as possible. 3 As soon as possible, have the cooling
system checked by an authorized Saab
dealer.
Towing a trailer
Trailer hitch attachmentTrailer hitch attachments are available as
accessories. These are designed for a max-
imum trailer weight of 3500 lbs. (1588 kg),
see also page 271.
Use only the electrical trailer hitch socket
provided in the trailer hitch kit.
Saab recommends:
 Use a Saab original hitch kit attachment
which is designed and tested by Saab.
 Consult your Saab dealer regarding the
appropriate hitch kit for your car.
WARNING
 Exercise care when opening the hood
if the engine is overheated. Never
remove the expansion tank cap com-
pletely when the engine is hot.
 The cooling system is pressurized -
hot coolant and vapor can escape.
These can cause injury to your eyes
and burns. Open the cap slowly to
release the pressure before
removing it.
WARNING
 When towing a trailer, do not attempt
to negotiate a hill having a gradient in
excess of 15 %. The weight distribu-
tion 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.
 Always apply the trailer’s handbrake
when unhitching it. There is otherwise
a risk of personal injury or damage to
the bumper should the trailer start to
roll.
NOTICEUse only a genuine Saab trailer hitch and
wiring, since other wiring methods can
cause expensive damage to the car’s
body and electrical system.
Consult an authorized Saab dealer for
guidance on how to connect the trailer
hitch electrical system.

179 Starting and driving
Trailer 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 271).
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

180 Starting and drivingWhen negotiating long hills, bear the follow-
ing important considerations in mind:
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.Recommendations for cars with
automatic transmission
Rises in coolant temperature are indicated
by the temperature gauge in the main instru-
ment panel.
The following steps are taken in order as the
temperature of the engine increases:
 Gear change pattern is altered.
 A/C compressor is switched off.
 Engine torque is reduced.
The following message will be displayed on
the SID if the transmission fluid becomes
too hot: “Gearbox too hot. Make a safe stop.
If this message appears, stop the car as
soon as it is safe to do so and allow the
engine to idle until the message has gone
out. The selector lever should be in
position P.When continuing your journey, select
manual mode and a gear in which the
engine speed is about 3,000 rpm until the
incline eases (see page 164).
Do not drive continuously with the WINTER
mode selected in hilly country when you are
towing a caravan, as this will increase fuel
consumption and risk overheating the trans-
mission.
VARNING
Remember to use the braking effect of the
engine (position D or L) when you are
descending long or steep hills to spare
the brakes.
Brake failure can result from overheated
brakes!
