146 Starting and drivingIgnition switchThe combined ignition switch and
gear-lever lock is located in the center con-
sole 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.
See also page 38.
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.

If the car does not startIf the text ”KEY NOT ACCEPTED” is shown
on the SID, after a failed start attempt, the
cause could be a fault in the transmitter in
the key, or in the receiver in the ignition lock.
The following should be done:
 Turn the key back to the LOCK position.
 Turn the key to ON.
 Press one of the buttons on the remote
control (the LED stops blinking).
 Start the engine.
Try another key. If this works, then the fault
is in the first key.
Contact an authorized Saab dealer for
checking and rectification.
Starting the engine
NOTETake care not to spill drinks or to drop
crumbs over the ignition switch. If dirt or
liquid gets into it, the switch may not
operate properly.
WARNING
 Always remove the key before leaving
the car.
 Always apply the parking brake before
removing the ignition key.
WARNING
 When starting the engine:
- Sit down in the driver’s seat.
- Depress the clutch pedal fully. The
clutch pedal must be fully depressed
or the starter will not engage.
- Never start the car from outside the
vehicle, e.g. through a wound down
window. This could lead to serious
personal injury.
 Engage reverse (R) (position P for
automatic transmission) to remove the
ignition key. The key can only be
removed in this gear position.
 Carbon monoxide (CO) is a colorless,
odorless, poisonous gas. Be alert to
the danger of CO – always open the
garage doors before starting the
engine in the garage.
 There is also a danger of CO poison-
ing if the exhaust system is leaking.

148 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
starter again, to give the battery time to
recover.
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
starter again, to give the battery time to
recover.
Let the engine idle for about 10 seconds. Do
not open the throttle wide for at least
2–3 minutes after starting.
Useful tips on cold climate starting If 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.  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.

149 Starting and driving
Limp-home modeThe car’s engine-management system
includes a diagnostic function that checks
numerous internal functions after the
engine has been shut off. If a fault is
detected in the throttle system, the
engine-management system puts the throt-
tle system into the limp-home mode. This
limits idling control, disables the cruise-con-
trol 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 53), indicating that you
should have the car checked as soon as
possible by an authorized Saab dealer.
Important
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
 The system is optimized for fuel with an
octane rating of AON 90. The 2.3 T
(Aero) and 3.0t V6 are optimized for
NOTEIf 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
flashes, it indicates that the engine is
misfiring which can result in damage to
the catalytic converter.

AON 93. One of the advantages of the
system is that it enables the engine to
be run safely on lower-grade fuel,
although not lower than AON 87.
 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.
Important considerations with cata-
lytic convertersThe catalytic converter is an emission-con-
trol device incorporated in the car’s exhaust
system. It consists of a metal canister with a
honeycomb insert, the cells of which have
walls coated in a catalytic layer (mixture of
precious metals).
To ensure that the catalytic converter con-
tinues to function properly, and also to avoid
damage to the converter and its associated
components, the following points must be
observed:
 Have the car serviced regularly in accor-
dance with the service program. The fuel
and ignition systems are particularly
important in this context.
 Always be alert to any misfiring of the
engine (not running on all cylinders) and
any loss of power or performance. At the
first sign of a malfunction, reduce speed
and take the car to an authorized Saab
dealer as soon as possible.
 If the engine fails to start (in very cold
weather or if the battery is flat), the car can
be push started (manual gearbox only) or
started using jumper cables to a donor
NOTEIf constant knocking occurs every time a
load is put on the engine, this indicates a
malfunction in the system.
Have the car checked without delay by an
authorized Saab dealer.
WARNING
If the engine is being run with the car on a
rolling road or dynamometer, 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 corre-
sponding road speed.
NOTEUse only unleaded gasoline. Leaded gas-
oline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.

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.
