132 Starting and drivingIgnition switchThe combined ignition switch and gear-
lever lock is located in the center console
between the front seats. The ignition key
can only be removed when reverse is
engaged (automatic transmission: selector
in ”P” position).
The key fits all the locks on the car. The key
number is specified on the small plastic
strap that comes with the keys when the car
is delivered. Keep a note of the key number
in a safe place, as you will need to quote it if
ordering a replacement key.

LOCK position Engage reverse and turn the key to LOCK.
Automatic transmission: select ”P”.
The gear lever is locked. This is the only position in which the key can be
removed.
The parking lights, hazard warning lights and interior lighting all work. OFF position Gear lever no longer locked.
Certain electrical circuits operationalON position All electrical circuits working.
Do not leave the key in the ON position
when the engine is not running.
Turn the key to OFF to switch off the
electrical circuits. In the ON position certain warning and indicator lights
come on as a check, and they normally are extinguished after about
3 seconds.
ST (starter) position The starter operates when the key is turned to this position. When
released, the key will spring back to the ON position. If the engine fails to
start, the key must first be turned back to the position between OFF and
LOCK before the starter can be operated again.
When the starter motor is running, several electrical circuits are
disconnected to facilitate starting.

134 Starting and drivingIt is possible for air to enter the lubricating
system in conjunction with an oil or oil-filter
change, or if the car has been stored for
some time. This air can cause the hydraulic
cam followers to emit a ticking noise, which
can persist for up to 15 minutes after start-
ing. Although this is quite normal and does
not indicate any malfunction, it is advisable
not to exceed 3,000 rpm before the noise
has disappeared.
The hydraulic cam lifters are completely
service free; the valve clearance is set up at
the factory and will not need any subse-
quent adjustment.
Starting the engineAvoid racing the engine or putting a heavy
load on it before it has warmed up. Drive
away as soon as the oil warning light has
been extinguished to enable the engine to
attain its normal temperature as quickly as
possible.
The engine has an automatic choke and
should be started as follows:Cars with manual transmission
To start the engine the clutch pedal must
be fully depressed.1 Depress the clutch pedal fully but do not
touch the accelerator.
2 Start the engine. Let the ignition key
spring back as soon as the engine has
started and is running smoothly – at very
low temperatures, you may need to run
the starter for up to 25 seconds. Wait
20–30 seconds before running the star-
ter again, to give the battery time to reco-
ver.
Note:
On cars with manual transmission, if the
starter fails to engage when the ignition key
is turned to the start position, make sure the
clutch pedal is full depressed. Misposi-
tioned floor mats or other obstructions
under the clutch pedal may affect starting.
Let the engine idle for about 10 seconds. Do
not open the throttle wide for at least 2–
3 minutes after starting.
Cars with automatic transmission 1 The selector lever must be in the P or N
position.
2 Keep your foot on the brake pedal.
3 Start the engine. Let the ignition key
spring back as soon as the engine has
started and is running smoothly – at very
low temperatures, you may need to run
the starter for up to 25 seconds. Wait
20–30 seconds before running the star-
ter again, to give the battery time to reco-
ver.
Let the engine idle for about 10 seconds. Do
not open the throttle wide for at least
2–3 minutes after starting.  The tail pipe of the exhaust system
can become very hot during driving.
Bear this in mind when loading and
unloading the car.
 Do not rest or sleep in the car when
parked with the engine running. There
is a risk of depressing the accelerator
which could lead to engine damage.

135 Starting and driving
Useful tips on cold climate
startingIf the engine has failed to start after several
attempts in very cold weather, press and
hold the accelerator down to the floor and
run the starter for 5–10 seconds. This will
prevent the engine being flooded (exces-
sively rich fuel-air mixture).
Now start the engine in the normal way – do
not touch the accelerator.
If the engine stalls immediately after starting
(e.g. if the clutch was released too quickly),
do not touch the accelerator when restarting
the engine.
Limp-home modeThe engine management system has a
diagnostic feature that continually checks a
number of internal functions. If, for example,
a fault is detected in the throttle valve, the
engine management system will go into
Limp-home mode.This limits idling control,
disables the cruise-control system and
limits the capacity of the A/C compressor.
If the limp-home mode is in operation
(”Engine malfunction (CHECK ENGINE)”
light on, see below) and the outside temper-
ature is close to or below freezing, you may
need to use some throttle on starting (some
pressure on the accelerator).
If the diagnostic system has detected a fault
in the engine-management system, the
”Engine malfunction (CHECK ENGINE)”
light on the main instrument panel will
come on (see page 55), indicating that you
should have the car checked as soon as
possible by an authorized Saab dealer.
NOTICEIf the CHECK ENGINE warning light
starts to flash, ease off the accelerator
slightly. If the light does not cease to flash
within 5 seconds, stop the car in a suita-
ble place as soon as possible and turn off
the engine. The car must be towed to an
authorized Saab dealer.
If the CHECK ENGINE warning light flas-
hes, it indicates that the engine is misfi-
ring which can result in damage to the
catalytic converter.

136 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 adjus-
ted automatically to the knocking or
pinging tendency of the engine. Occa-
sional, 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 an authori-
zed 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.

140 Starting and drivingFilling a portable fuel container Fuel (Gasoline Engine)
FuelUse of the recommended fuel is an impor-
tant part of the proper maintenance of your
vehicle.
For optimum performance Saab recom-
mends:
2.3t 185 hp (Linear) – AON 90.2.3T 220 hp (Arc) and
2.3 Turbo 250 hp (Aero) – AON 93.
Gasoline OctaneFor the 2.3T and 2.3 Turbo, use premium
unleaded gasoline with a posted octane of
93 or higher for best performance. For the
2.3t, use a mid-grade with a posted octane
of 90 for best performance. You may also
use regular unleaded gasoline rated at
87 octane or higher, but your vehicle's
acceleration may be slightly reduced. If the
octane is less than 87, you may get a heavy
knocking noise when you drive. If this
occurs, use a gasoline rated at 87 octane or
higher as soon as possible. Otherwise, you
might damage your engine. A little pinging
noise when you accelerate or drive uphill is
considered normal. This does not indicate a
problem exists or that a higher-octane fuel
is necessary. If you are using 87 octane or
higher-octane fuel and hear heavy knock-
ing, your engine needs service.
Gasoline SpecificationsIt is recommended that gasoline meet spec-
ifications which were developed by automo-
bile manufacturers around the world and
contained in the World-Wide Fuel Charter
which is available from the Alliance of Auto-
mobile Manufacturers at www.autoalli-
ance.org/fuel_charter.htm. Gasoline meet-
ing these specifications could provide
improved driveability and emission control
system performance compared to other
gasoline.California FuelIf your vehicle is certified to meet California
Emission Standards (see the underhood
emission control label), it is designed to
operate on fuels that meet California speci-
fications. If this fuel is not available in states
adopting California emissions standards,
your vehicle will operate satisfactorily on
fuels meeting federal specifications, but
emission control system performance may
be affected. The malfunction indicator lamp
may turn on and your vehicle may fail a
smog-check test. See Engine malfunction
(CHECK ENGINE) on page 55. If this
occurs, return to your authorized Saab
dealer for diagnosis. If it is determined that
the condition is caused by the type of fuel
used, repairs may not be covered by your
warranty.
WARNING
Never fill a portable fuel container while it
is in your vehicle. Static electricity
discharge from the container can ignite
the gasoline vapor. You can be badly
burned and your vehicle damaged if this
occurs. To help avoid injury to you and
others:
 Dispense gasoline only into approved
containers.
 Do not fill a container while it is inside
a vehicle, in a vehicle’s trunk, pickup
bed or on any surface other than the
ground.
 Bring the fill nozzle in contact with the
inside of the fill opening before opera-
ting the nozzle. Contact should be
maintained until the filling is complete.
 Do not smoke while pumping gaso-
line.

146 Starting and drivingIf ”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 57).
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 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 an authorized Saab dealer (see
also page 161).

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 trai-
ler attached.

148 Starting and drivingSentronic, 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, engines are
much more responsive to changes in acce-
lerator position. The accelerator has a diffe-
rent 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.

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 unexpec-
tedly.
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). MMove the selector lever from position D to M to
allow you to change gear manually. Refer to
page 148.LSelect position L if you wish to drive in 1st gear.
No upchanges will be made if you pull off in posi-
tion L. If you move the selector lever from posi-
tion D or M to L at a high vehicle speed, the
transmission will automatically shift down
through 4th, 3rd and 2nd gears to 1st gear,
depending on the car’s speed. Use this position
for descending steep hills if the car is heavily loa-
ded to spare the brakes.
