122 Starting and drivingIgnition switchThe ignition switch is located on the center
console between the front seats. In cars
with automatic transmission, the remote
control can only be removed when the
selector lever is in position P.NOTICETake 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 remote control
before leaving children unattended in
the car.
 Apply the parking brake before remov-
ing the remote control.
 Never remove the remote control
while the car is moving. This will acti-
vate the steering wheel lock and make
it impossible to steer the car.
LOCK position
The position lights, hazard warning lights and interior lighting can be
turned on.
Cars with automatic transmission: Move the gear lever to P.
The gear lever is locked in position. This is the only position in which the
remote control can be removed.
Cars with manual transmission: The remote control can be removed
regardless of the position of the gear lever.
OFF position
Parts of the electrical system are operative.
Do not leave the remote control in the OFF position with the engine
not running as this could cause the battery to run flat in a matter of
hours.
Cars with automatic transmission: The gear lever is not locked. See
also page 135.
ON position
The entire electrical system is operative.
Do not leave the remote control in the ON position when the engine
is not running.
Turn the remote control to the OFF position to disconnect the electrical
system.
When you turn the remote control to ON, some indicator and warning lights
will come on in the main instrument panel. These should go out after about
3 seconds.
ST - starter position
The starter motor operates (automatic transmission: selector lever must
be in P or N) when the remote control is turned to this position. When
released, the remote control will spring back to the ON position.
The car has an electronic restart lock. If the engine fails to start, the remote
control must first be turned back to a position between OFF and LOCK
before the starter motor can be operated again.

123 Starting and driving
Steering wheel lockThe steering wheel lock is electronic. The
lock engages when the remote control is
removed from the ignition and unlocks when
the remote control is inserted. A click can be
heard when the steering wheel lock locks
and unlocks.
If the car is parked with one front wheel
touching the curb, for example, you may
need to turn the steering wheel slightly
when you insert the remote control to allow
the steering wheel lock to unlock. If you do
not succeed on first attempt you must
remove the remote control before trying
again. Turn the steering wheel and insert
the remote control into the ignition switch.
If the steering wheel lock does not disen-
gage it will not be possible to turn the remote
control in the ignition switch.
The following message is shown on the SID:If a fault arises affecting the steering wheel
lock, the following message will be
displayed on the SID:
If the steering wheel lock malfunctions while
the remote control is in the ignition switch,
this may prevent the removal of the remote
control or prevent the car from being
restarted once the engine has been
switched off.
If you have to leave the car, lock the car by
pressing down the lock buttons on the
doors. Lock the front left door from outside
with the traditional key (see page 40). The
car is now locked but the alarm is inactive.
Starting the engine
Steering wheel locked.
Pull out key, turn steering
wheel. Try again.
Steering lock malfunc.
Make a safe stop.
Contact Saab dealer.
WARNING
 When starting the engine:
- Sit down in the driver’s seat.
- Depress the clutch pedal fully. If the
gear lever is not in the neutral position,
the clutch pedal must be fully
depressed or the car will jump
forwards or backwards, which may
cause a crash.
- Never start the car from outside the
vehicle, e.g. through a window that is
down. This could lead to serious
personal injury.
 Cars with automatic transmission:
select position P 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.
 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.
 There is also a danger of CO poison-
ing if the exhaust system is leaking.

124 Starting and drivingDo not run the starter motor for more than
25 seconds at a time. Wait 20–30 seconds
before running the starter again, to give the
battery time to recover.
Avoid racing the engine or putting a heavy
load on it before it has warmed up. Let the
engine idle for at least 10 seconds and then
drive away as long as the engine oil warning
light has gone out to enable the engine to
attain its normal temperature as quickly as
possible
It 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.
Starting the engineAvoid racing the engine or loading it heavily
before it has warmed up. Do not drive away
before the warning and indicator lights have
gone out.
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 Make sure the parking brake is applied.
2 Depress the clutch pedal but do not
touch the accelerator.
3 Start the engine. Let the remote control
spring back as soon as the engine has
started and is running smoothly.
Allow the engine to idle for about
10 seconds. Do not apply full throttle for at
least 3 minutes after starting.Cars with automatic transmission
The selector lever must be in the P or N
position.
1 The selector lever must be in the P or N
position.
2 Keep your foot on the brake pedal.
Note! Once the engine has started, the
brake pedal will sink. This is perfectly
normal.
3 Start the engine. Let the remote control
spring back as soon as the engine has
started and is running smoothly.
Allow the engine to idle for about
10 seconds. Do not apply full throttle for at
least 3 minutes after starting.

125 Starting and driving
Useful tips on starting the engineIf the engine has failed to start after several
attempts in very cold weather, proceed as
follows:
1 Turn the ignition switch to ON (it is
essential that you turn the ignition to
ON before depressing the accelerator).
2 Press the accelerator to the floor and run
the starter motor for 5-10 seconds. This
will prevent the engine being flooded
(fully depressed accelerator cuts off the
fuel supply).
3 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.
Important
considerations for
driving1 Starting and driving
 Do not use full throttle until the engine
is warm, so as to avoid unnecessary
wear. If the needle of the turbo gauge
repeatedly enters the red zone, the
engine may suddenly lose power, due
to the initiation of a monitoring system
that limits the boost pressure. Contact
a Saab dealer as soon as possible.
 Under certain barometric conditions
(high outside temperature and/or high
altitude) the needle may enter the first
part of the red zone without necessarily
indicating that a fault has arisen.
 A protective function (interruption of the
fuel supply) limits the engine speed.2 Stopping the engine
 Do not rev the engine immediately
before switching it off - stop the engine
when it is idling.
3 Regulating the charging pressure
 The system is optimized for AON 90.
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. Severe engine damage
will occur if gasoline lower than 87
octane is used. However, engine
performance will fall slightly and heavy
loading and laboring should be
avoided. For optimum performance,
use the recommended grade of fuel.
 The maximum boost pressure is regu-
lated according to the tendency of the
engine to knock. Short-lived knocking
is perfectly normal. This can occur
when the engine is running at about
3,000 rpm under a heavy load. The
extent of this knocking will depend on
the grade of fuel in the tank.
 Isolated instances of knocking can
occur with low-octane fuel. This
controlled form of knocking, followed
by a reduction in the boost pressure, is
a sign that the control system is work-
ing normally, and is perfectly safe for
the engine.

126 Starting and drivingLimp-homeThe engine management system has a
diagnostic feature that checks a number of
internal functions. If a fault is detected in the
throttle valve, the engine management
system will set the throttle system to the
limp-home mode. This means:
 idling control will be poor (uneven idling
since regulated by ignition and fuel
supply)
 engine performance will be reduced
 the cruise control will not function
 the capacity of the A/C compressor will be
limited.If the diagnosis function detects a fault in the
engine management system, the light
"Engine malfunction (CHECK ENGINE)" in
the instrument panel will come on (see page
55). Have the car checked at a Saab dealer
as soon as possible.
The following message is shown on the SID:
Important considarations with
catalytic 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 (precious
metal alloy).
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:
NOTICE If the engine sounds strange there is a
malfunction. Contact a Saab dealer
immediately.
 The use of fuel with too low an octane
rating can cause serious engine
damage.
Reduced engine power.
Contact Saab dealer.
NOTICEIf "Engine malfunction (CHECK
ENGINE)" warning light starts to flash
(indicating that the engine is misfiring and
the catalytic converter can be damaged),
ease off the accelerator slightly. The light
should go out or start to shine constantly.
If the light continues to flash despite
easing off the accelerator, you may
continue to drive the car but at the mini-
mum throttle permitted by the current traf-
fic situation. Have the car checked as
soon as possible at a Saab dealer.
NOTICEUse only unleaded gasoline. Leaded
gasoline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.

127 Starting and driving
 Have the car serviced regularly in accord-
ance with the service program.
 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 a Saab dealer.
 If the engine fails to start (in severe cold
or if the battery is flat), the car can be
bump started (manual transmission only)
or started using jump leads to a donor
battery. However, as soon as you have
started the engine, it is important that it
runs on all cylinders. If it is misfiring, allow
it to idle for up to 5 minutes to give it time
to settle and run smoothly. If, after this
time, the engine still fails to run properly,
switch off the engine to avoid serious
damage to the catalytic converter.
Contact a Saab dealer for advice. Never park the car on dry grass or other
combustible material. The catalytic
converter gets very hot and could there-
fore start a fire.
 Never drive off if the engine is misfiring.
 If you bump start the car when the engine
is already at normal working temperature,
the engine must start to run on all cylin-
ders. Abort bump starting if the engine
fails to start immediately.
Failure to strictly follow these instructions
can result in damage to the catalytic con-
verter and associated components, and
could represent a breach of the warranty
conditions.
NOTICEIf the car runs out of gas, air may be drawn
in with the fuel, which, in turn, can cause
the catalytic converter to be damaged by
overheating.
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 obtain at the corre-
sponding road speed.

128 Starting and drivingRefuelingOnly use fuel from a well-known oil com-
pany.
All Saab gasoline engines can be driven on
gasoline with an octane rating between
AON 87–93.
The engine management system monitors
the combustion and automatically adapts to
the fuel used.
Always use the correct grade of fuel:
unleaded AON 87–93.For optimum performance Saab recom-
mends:
2.0t engine 175 hp – AON 90.
2.0 Turbo engine 210 hp - AON 93.
Sometimes, gasoline can contain a number
of additives containing oxygen. The most
common of these are alcohol or some type
of ether. The maximum oxygen level is
restricted by national regulations.
If fuel containing a mixture of alcohol is
used, the maximum levels approved by
Saab are: 5 % by volume of methanol; or
10 % by volume of ethanol. The most
common type of ether used is MTBE
(methyl tertiary butyl ether), of which fuel
may contain a maximum of 15 % by volume.
WARNING
Gasoline fumes are highly explosive.
Therefore:
never smoke while refueling
never use gasoline for any purpose
other than as engine fuel
 gasoline is extremely flammable and
can cause severe burns. No open or
exposed flames near gasoline
 do not use a mobile phone at the same
time as refueling
NOTICE Do not overfill. Fuel should not come
right up the filler pipe as room for
expansion is needed for when the
temperature rises.
 The use of fuel with too low an octane
rating can cause serious engine
damage.
