146 Starting and drivingImportant
considerations for
drivingThe engine-management system in the
Saab 9-5 is called Saab Trionic T7. The
system manages the ignition, fuel injection
and turbo boost pressure.
The Trionic T7 system developed by Saab
is an intelligent engine-management
system designed to achieve optimum driv-
ability under differing driving conditions.
The system makes adjustments automati-
cally, for instance, if the car is being driven
at altitude (oxygen-deficient air), for differ-
ent grades of fuel (AON 87–93) and for dif-
ferent load conditions.
1 Starting and driving
Refrain from using full throttle before
the engine has warmed up (before
needle in mid-range on temperature
gauge).
A safety function prevents the engine
from revving faster than 6,000 rpm by
limiting the induction air.
2 Stopping the engine
Do not rev the engine immediately
before switching it off – stop the engine
when it is idling.
3 Regulating the boost pressure
One of the advantages of boost pres-
sure regulation is that the engine can
also be run safely on gasoline with a
lower octane rating, although not lower than AON 87. However, engine perfor-
mance will fall slightly and heavy load-
ing and laboring should be avoided. For
optimum performance, use the recom-
mended grade of fuel.
The maximum boost pressure is
adjusted automatically to the knocking
or pinging tendency of the engine.
Occasional, short-lived knocking when
the engine is under a heavy load is per-
fectly normal; the extent will depend on
the grade of fuel in the tank.
Isolated instances of knocking are
more likely to occur with low-octane
fuel. This controlled form of knocking,
followed by a reduction in the boost
pressure, is a sign that the wastegate is
functioning and is perfectly safe for the
engine.
NOTICE If the engine sounds strange there is a
fault in the system. Have the car
checked without delay by a workshop.
We recommend that you contact an
authorized Saab dealer.
The use of fuel with too low an octane
rating can cause serious engine
damage.
WARNING
If the engine is being run with the car on a
rolling road or dynamometer, longer than
for a standard state emission inspection,
to ensure adequate cooling, air must be
blown into the engine compartment and
under the car at a rate equivalent to the
ram-air effect that would be obtained at
the corresponding road speed.

149 Starting and driving
Refueling
1 Switch off the engine.
2 Open the filler cap, located in the
right-hand rear fender.
3 Insert the fuel pump nozzle beyond the
flange on the filler pipe and let the first
mark (a ring, a pimple or the first
spring-coil) rest on the flange. Do not
withdraw the nozzle while filling is in
progress.
4 Cease refueling the first time the pump
stops, and wait a few seconds after
you´ve finished pumping before you
remove the nozzle.Filler cap
When you put the filler cap back on, turn it
to the right (clockwise) until you hear three
clicks. Make sure you fully install the cap.
The most effective way to prevent conden-
sation forming in the tank (and thus avoid
possible running problems) is to keep the
tank well filled.
Before the onset of freezing temperatures in
winter, it may be advisable to add gasoline
anti-freeze to the fuel a few times to dispel
any condensation in the system.The fuel door has a built in filler cap holder
slot located on the fuel door. Slide the white
ring on the cap into the slot.
Notice: If you need a new fuel cap, be sure
to get the right type. Your dealer can get one
for you. If you get the wrong type, it may not
fit properly
WARNING
If a fire starts while you are refueling, do
not remove the nozzle. Shut off the flow of
fuel by shutting off the pump or by notify-
ing the station attendant. Leave the area
immediately.
NOTICE Fill to maximum filling capacity.
Stop filling after the first time that the
nozzle trips to shut off the flow of fuel.
Filling capacity can differ between
different fuel stations and outside
temperature. Fuel tank volume when
nozzle trips to shut off, may vary by
0.5 gal. (2 liters).
Do not fill fuel all the way up the filler
pipe. The gasoline must be allowed
room for expansion especially during
hot weather.
When refueling, hang the filler cap inside
the fuel door

156 Starting and drivingIf ”Automatic transmission, fault indicator”
appears on the main instrument panel,
the system has detected a fault in the auto-
matic transmission or its control module
(see page 62).
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 a workshop. We recom-
mend that you contact an authorized Saab
dealer.
It is not possible to select the SPORT 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:
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 a workshop. We recommend that
you contact an authorized Saab dealer (see
also page 176).

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.

157 Starting and driving
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 176).
Towing Towing of cars with automatic transmission,
see page 185.
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.
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!

158 Starting and drivingSentronic, manual modeMove the selector lever to the M position.
Select a higher gear by pushing the
right-hand paddle on the steering
wheel. Select a lower gear by pushing the
left-hand paddle on the steering wheel.
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, engines are
much more responsive to changes in accel-
erator position. The accelerator has a differ-
ent 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.

162 Starting and drivingTo 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).
When the ESP system is operative for
more than 1 second.
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 D or L.
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 a
workshop. We recommend that you con-
tact an authorized Saab dealer.

163 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 unre-
sponsive.
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.

165 Starting and driving
Electronic Stability
Program (ESP)The Electronic Stability Program employs
both the antilock braking system (ABS) and
the traction control system (TCS). It is a
system that helps the driver to stabilize the
car in unusual circumstances that would
otherwise be more difficult to handle.
How the ESP system worksThe Electronic Stability Program can help to
prevent the car from skidding by braking
one or several wheels independently of the
driver. The engine output is then also
reduced to prevent the driving wheels from
spinning. The car has sensors that measure
wheel speed, yaw acceleration, lateral
acceleration, steering wheel position and
braking pressure. The values provided by
these sensors are used to calculate the
actual direction of the car. If this direction
does not agree with that intended by the
driver, calculated from the steering wheel
position, the ESP is engaged.
ESP improves the driver’s chances of
retaining control over the car in critical situ-
ations.
To ensure that the system works as
designed, the dimensions of all four tires
must be the same.
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.

166 Starting and drivingESP indicator lightThe indicator light on the main instru-
ment 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.ESP OFFThe light on the main instrument
comes on if:
A fault has been detected and the system
has therefore been switched off.
The system has been switched off manu-
ally.
When the ignition key is turned to the ON
position, the lamp is lit for about four sec-
onds while the system undergoes a
self-test.
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.NOTICESuspension modifications, such as
changing the type of wheels, dampers or
springs, can affect the function of the ESP
system.
Always consult a workshop before chang-
ing any suspension components. We rec-
ommend that you contact an authorized
Saab dealer.

170 Starting and drivingSaab Parking
Assistance
The parking aid system facilitates parking
and reversing. There are four sensors in
the rear bumper that detect objects up to
6 feet (1.8 metres) behind the car.The system uses four sensors in the rear
bumper. These emit ultrasound signals that
bounce back to the sensors off any objects
behind the car. The system, however,
cannot always detect small or narrow
objects or objects that do not reflect ultra-
sound back towards the car, such as pipes,
or the corner of a house or rectangular post.The system is activated automatically when
reverse is engaged or selected. When the
sensors detect an object within the moni-
tored area, the SID will display the text
"PARK ASSIST" and pulses of sound
(- - - - -) will be heard. The frequency of the
pulses increases as the car comes closer to
the object.
When the distance to the object is less
than 12 in. (30 cm), a continuous tone
will be heard.
WARNING
Responsibility always lies with the driver
when reversing.
Saab Parking Assistance can facilitate
reversing at low speeds, such as when
reverse parking.
Bear in mind that small and/or narrow
objects cannot always be detected by
the system.
