159 Starting and driving
Opening the fuel filler door in an emergency,
see page 150.
Recommended fuel:The engine in your Saab 9-5 is designed to
operate on unleaded gasoline that has an
octane rating of 87 or higher. Octane rating
is determined according to the formula:
where MON is the Motor Octane Number,
and RON is the Research Octane Number.
The average of these two values is the
octane rating of the gasoline as it appears
on the pump at a retail gas station. This
value is sometimes referred to as the
"Anti-Knock Index" (AKI) or the "Average
Octane Number" (AON).
To avoid deposit formation on the fuel injec-
tors which can cause poor driveability, use
only quality gasolines that contain deter-
gents and corrosion inhibitors. Because
gasolines sold at retail gas stations vary in
their composition and quality, you should
switch to a different brand if you begin expe-
riencing driveability and/or hard starting
problems shortly after refueling your car. In
recent years, a variety of fuel additives and
alcohols or oxygenates have been blended
with gasoline. These types of gasolines may
be found in all parts of the United States and
Canada, but particularly in geographic
areas and cities that have high carbon mon-
oxide levels. Saab approves the use of such
"reformulated" gasolines in its products,
which help in reducing pollution from all
motor vehicles, provided that the following blending percentages are met by such
fuels:
Up to 10 % ethanol by volume, with corro-
sion inhibitors.
Up to 15 % MTBE by volume (methyl ter-
tiary butyl ether).
Up to 5 % methanol by volume, with an
equal amount of a suitable co-solvent and
added corrosion inhibitors.
Other, less common, fuel additives used by
some gasoline dealers are also acceptable,
provided that the resultant gasoline is not
more than 2.7 % oxygen by weight.
Some Canadian and U.S. gasolines contain
an octane enhancing additive called meth-
lycyclopentadienyl manganese tricarbonyl
(MMT). If such fuel is used, your emission
control system performance may deterio-
rate and the malfunction indicator lamp on
your instrument panel may turn on. If this
occurs, return to your authorized Saab
dealer for service.
However, these blended gasolines are reg-
ulated and should never exceed these rec-
ommended blend percentages and service
station operators should know if their gaso-
lines contain detergents and oxygenates,
and have been reformulated to reduce vehi-
cle emissions. Nevertheless, if you begin to
notice a problem with the way your car starts
or runs shortly after it has been refueled, try
a different brand of gasoline.
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.

161 Starting and driving
Be sure the posted octane is at least 87. If
the octane is less than 87, you may get a
heavy knocking noise when you drive. If it’s
bad enough, it can damage your engine. If
you’re using fuel rated at 87 octane or
higher and you hear heavy knocking, your
engine needs service. But don’t worry if you
hear a little pinging noise when you’re accel-
erating or driving up a hill. That’s normal,
and you don’t have to buy a higher octane
fuel to get rid of pinging. It’s the heavy, con-
stant knock that means you have a problem.
If your vehicle is certified to meet California
Emission Standards (indicated on the
underhood emission control label), it is
designed to operate on fuels that meet Cal-
ifornia specifications. If such fuels are not
available in states adopting California emis-
sions standards, your vehicle will operate
satisfactorily on fuels meeting federal spec-
ifications, but emission control system per-
formance may be affected. The ”Engine
malfunction (CHECK ENGINE)” indicator
on your main instrument panel may turn on
and/or your vehicle may fail a smog-check
test. See ”Engine malfunction (CHECK
ENGINE)” indicator on page 59. If this
occurs, return to your authorized Saab
dealer for diagnosis to determine the cause
of failure. In the event it is determined that
the cause of the condition is the type of fuels
used, repairs may not be covered by your
warranty. Some gasolines that are not reformulated
for low emissions may contain an
octane-enhancing additive called methylcy-
clopentadienyl manganese tricarbonyl
(MMT); ask your service station operator
whether or not the fuel contains MMT. Saab
Automobile AB does not recommend the
use of such gasolines. If fuels containing
MMT are used, spark plug life may be
reduced and your emission control system
performance may be affected. The malfunc-
tion indicator lamp on your instrument panel
may turn on. If this occurs, return to your
authorized Saab dealer for service.
Engine Break-In PeriodPistons, bores and bearings need time to
obtain uniform, wear-resistant surfaces.
If a new engine is driven too hard, this grad-
ual process of bedding-in will not be possi-
ble and the life of the engine will be short-
ened.
During the first 1,200 miles (2,000 km), do
not exceed 5,000 rpm.
In addition, refrain from driving the car at full
throttle, other than for brief instances,
during the first 1,800 miles (3,000 km). Wearing in new brake padsNew brake pads take time to bed in, about
90 miles (150 km) if the car is driven largely
under stop-and-go conditions or about
300 miles (500 km) of highway driving.
To extend the useful life of the pads, avoid
hard braking as much as possible during
this period.

162 Starting and drivingGear changingManual transmissionTo start the engine the clutch pedal must
be fully depressed.
The gear positions are marked on the gear
lever. Before reverse (R) can be engaged,
you must lift the ring underneath the
gear-lever knob.
To change gear, fully depress the clutch
pedal and then release it smoothly. It is
inadvisable to drive with your hand resting
on the gear lever, as this can increase the
wear on the transmission.
When changing down from 5th to 4th gear,
ease the gear lever straight back, without
applying any lateral pressure. This will pre-
vent 2nd gear being engaged by mistake,
which can result in overreving and possible
damage to the engine.
Before engaging reverse, wait till the car is
at a standstill, release the accelerator and
fully depress the clutch. From neutral, press
the gear lever firmly to the right before
easing it back into reverse.
Shift-up indicator for improved fuel
economy (U.S. models only)Cars equipped with a manual transmission
have a "Shift-up" light on the instrument
panel. The light begins to work after the
vehicle is warmed up and provides you with
a good indication when to shift to a higher
gear.
It is not necessary or recommended to
follow the shift-up recommendations in all
driving conditions, for example, when driv-
ing in heavy urban traffic or steep downhill
grades.
However, shifting with the light should result
in improved fuel economy. Therefore, for
reduced fuel consumption and better
energy conservation, you should make a
habit of shifting before or when the shift-up
light comes on.Towing Towing of cars with manual transmission,
see page 189.
NOTICEWhen the reverse gear is to be engaged
the car must be at a standstill with the
accelerator fully released. Lift the reverse
lock-out collar and push the gear lever
firmly to the right in neutral before easing
it into reverse.

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. If manual mode (M) is selected, the
current gear is also displayed 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.
If you want to leave the car with the
engine running, move the selector
lever to P or N and apply the parking
brake.
NOTICEAfter selecting a drive position, pause
briefly to allow the gear to engage (the car
starts to pull a little) before you acceler-
ate.
Selector lever
Selector-lever indicator on main instru-
ment panel
ProCarManuals.com
164 Starting and drivingThe detent button on the selector lever has
to be pressed before the selector can be
moved between certain positions. Four modes for the automatic transmission
can be selected: Normal, Manual, Sport and
Winter.
The Normal mode, which provides the best
fuel economy, is the default setting when
the engine is started.
Manual mode (Sentronic): see page 167.
When the Sport mode is selected, the
throttle angle is altered to provide more
power at the same throttle setting. The
transmission also changes up later than in
Normal mode to provide higher perfor-
mance. In this mode, the SPORT indicator
will appear on the main instrument panel
(see page 170).
The Winter mode is intended for use when
pulling away and driving on icy roads. In this
mode, the transmission starts in 3rd gear, to
provide better grip, and the WINTER indica-
tor appears on the main instrument panel.
When the ignition is turned to OFF, the auto-
matic transmission will automatically revert
to Normal mode (see page 170).
Adaptive gear-change pattern is a trans-
mission function in the Normal and Sport
modes which matches gear changing to
current driving conditions. The transmission
control module senses the load on the
engine and temperature of the transmis-
sion. A suitable gear change pattern is then
selected automatically to avoid unneces-
sary gear changes and undesired tempera-
ture increases in the transmission.
Lock-up function The automatic transmission has a lock-up
function, which can render the torque con-
verter inoperative in 3rd, 4th and 5th gears,
thus reducing the engine speed and fuel
consumption.
When the lock-up function comes into oper-
ation, it may give the impression of an over-
drive being engaged.Kick-downWhen the accelerator is pressed down hard,
a change-down to the next gear will be
effected to provide maximum acceleration,
e.g. for overtaking.
Following this, the next higher gear will be
selected at the optimum engine speed for
acceleration or, if you ease off the acceler-
ator, before reaching this.
Detent positions for selector movement
ProCarManuals.com
165 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 228). 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.
1 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
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 61).
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.

167 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 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.
Paddles on the steering wheel for
changing gear manually
ProCarManuals.com
169 Starting and driving
If you move the selector lever from D to L, downchanges will follow
a set pattern to avoid damaging the engine or transmission.
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 and the present temperature of the transmis-
sion. The function is available in Normal and Sport modes.
The changes occur at a higher engine speed and the car remains in
the same gear for longer, if the transmission control module senses
that the load has not decreased. These gear-change patterns pre-
vent unnecessary changing up and down, when for example driving
up or down long slopes with a trailer or caravan, and to prevent over-
heating the transmission oil. The adaptive gear-change function is
also selected automatically when the transmission oil becomes too
hot, to protect the transmission itself from damage and to lower the
oil temperature.
The adaptive gear-change pattern function is deselected when:
Winter mode is selected.
The engine is switched off.
The load is reduced so much that the function is no longer
required.
”Automatic transmission, fault indicator” appears on main
instrument panel, see page 165.
