Movement sensorThe movement sensor monitors the cabin.
The alarm will be triggered if a movement is
detected, such as if someone sticks in their
arm through a smashed window.
Note: Always contact your Saab dealer if
you intend to use a separate cabin heater as
this can interfere with the movement
sensor.Disabling the movement and tilt sensors
If, for example, you leave a dog in the car or
park on a ferry, you should disable the sen-
sors as described below:
1 Go to Profiler by pressing the CUSTOM-
IZE button (see also 64).
2 Turn the INFO dial until Theft Alarm is
selected.
3 Press in the INFO dial.
4 Select Door alarm only.
5 Confirm this selection by pressing the
INFO dial.
The movement and tilt sensors will be reac-
tivated automatically the next time you start
the car. You can activate the sensors man-
ually before the engine is started as
described above.
NOTICE It is possible to inadvertently deacti-
vate the car alarm and at the same
time unlock the car, if the button on the
key is pressed by mistake when the
car is still within its range. The car will
be locked automatically after
3 minutes.
 When locking the car by remote
control in extremely cold weather, it is
advisable to check that the lock
system has operated properly. To do
so, check that the interior locking
buttons are all down.
If not, unlock and relock the car again.

Engine malfunction
(CHECK ENGINE)
WARNING
An illuminated “Engine malfunction
(CHECK ENGINE)” indicator light indi-
cates an engine-related problem. While
your car may be able to be driven with the
“Engine malfunction (CHECK ENGINE)”
indicator light illuminated (limp-home
mode), you are advised to have your car
serviced at an authorized Saab dealer as
soon as possible.
Continued driving without this problem
being corrected might cause serious
further damage to your car and create
unsafe driving conditions. The operator
should be prepared to take action if such
unsafe conditions arise (e.g. brake
smoothly, engage neutral, stop in a suita-
ble place, switch off the engine, etc.)
Engine malfunction.
Contact Saab dealer.
NOTICEThe car should be checked immediately
at a Saab dealer to prevent more serious
faults from arising.
High beam Indicator

56 Instruments and controlsThis light indicates when the front fog lights
are on (see page 74).
The front fog lights are switched off auto-
matically when the engine is switched off.
When the fog lights are next needed, they
will have to be switched on manually.
This light indicates when the rear fog light is
on (see page 74).
The rear fog light is switched off automati-
cally when the engine is switched off. When
the fog light is next needed, it will have to be
switched on manually again.This light should come on briefly when you
turn the ignition key to ON. If it doesn´t come
on, have it fixed so it will be ready to warn
you if there is a problem. This light indicates
when the brake fluid level is too low (see
page 180).
The following message is shown on the
Saab Information Display (SID):For safety reasons, stop the car and check
the level of the brake fluid (see page 180).
If the level is normal, depress the brake
pedal firmly two or three times. Now check
the level again. If the level is still normal, you
may drive the car, with considerable cau-
tion, to the nearest Saab dealer to have the
brake system checked.
The brake system provides Electronic
Brakeforce Distribution (EBD). This distrib-
utes the brake pressure between the front
and rear wheels, in such a way as to achieve
optimum braking performance irrespective
of the car’s load.
If a fault arises in the EBD function, the ,
and lights will come on. Also, the fol-
lowing message will appear on the Saab
Information Display (SID):
If this is the case, drive carefully and contact
a Saab dealer as soon as possible. Refer to
Brake warning light on page 56, Antilock
braking warning on page 54 and TCS OFF
or ESP OFF indicator (certain variants only)
on page 63.

58 Instruments and controlsThis light comes on when there is less than
about 2.5 gallons (10 litre) of fuel left in the
tank.
This light indicates that the headlights or
parking lights are on.This light comes on when the system is
engaged.
This symbol can be found in cars with
manual transmission. The symbol is not
activated until the engine is warm.
It is not always necessary or even recom-
mended to shift up to a higher gear when
this symbol lights up, such as when driving
in heavy traffic or down a steep hill.
Changing up a gear when the symbol
comes on does however improve fuel econ-
omy. Make it a habit to shift up when the
symbol lights up.
Autochecking of lights, main
instrument panelThe warning and indicator lights shown
above should come on when the ignition
switch is turned to ON. They should go out
after about 4 seconds once the engine has
started or after the fault-free self-diagnosis
of each system or function.

60 Instruments and controlsSpeedometer (U.S. speedometer
shown)The speedometer displays the speed of the
car in miles per hour (mph). It receives infor-
mation about vehicle speed from the ABS’s
wheel sensors.
Temperature gaugeThe temperature gauge shows the temper-
ature of the coolant. The needle should be
in the middle of the scale when the engine
is at normal operating temperature.
If the needle goes into the red zone (which
can occur at high outside air temperatures
or under heavy engine loads), choose the
highest possible gear ratio and the lowest
possible engine speed, and avoid shifting
down.If the needle repeatedly enters the red zone,
stop the car as soon as it is safe to do so and
check the coolant level (see page 179).
NOTICEIf the needle, despite the above action,
enters the red zone, stop the car in a suit-
able place and allow the engine to idle. If
the needle continues to rise, switch off the
engine.
WARNING
Never open the cap of the expansion tank
completely when the engine is hot, open
with care. The pressure in the cooling-
system can cause hot coolant and steam
to be released. Failure to heed this warn-
ing may result in personal injury.

Headlight levelling(cars with Bi-Xenon headlights)
Cars with Bi-Xenon headlights are
equipped with an automatic headlight level-
ling system, with self-calibrates each time
the vehicle is started. If a fault arises in the
automatic headlight levelling system, the
headlights will be angled down to avoid daz-
zling drivers in oncoming traffic. Adjust your
speed accordingly as the range of the head-
lights will be reduced. Check fuse 20 in the
engine bay fuse box (see page 203).
A fault in the system will produce the follow-
ing message on the Saab Information Dis-
play (SID):
Special equipment is required for adjusting
the basic headlight alignment.Headlight levelling

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.
