Priority of audible informationIf two or more functions are active simulta-
neously, the most important function at that
time will be prioritized.
If, for example, the direction indicators are
active when you engage reverse, the park-
ing assistance (if fitted) will be heard instead
of the direction indicators. When reverse is
disengaged, the direction indicators will be
heard, if they are still active.
Wipers and washersWindshield wipersPosition 1 is a spring-loaded position that
will produce a single sweep of the wipers.
The wipers always return to their home posi-
tion when the ignition is turned off.
To leave the wipers positioned vertically on
the windshield, proceed as follows:
1 Switch off the engine and remove the
remote control.
2 Activate the wipers within the next
16 seconds by pressing the stalk switch
down.
When the ignition is next switched on the
wipers will return to their home position.
Changing wipers blades, see page 216.
Rain sensorWhen the rain sensor is activated the follow-
ing symbol is displayed in SID .
The rain sensor automatically controls the
windshield wipers. The sensor is located on
the windshield beside the rearview mirror.
The system varies the frequency of wiping
between single sweeps and continuous
wiping, depending on the amount of pre-
cipitation.
WARNING
Turn the rain sensor off if the ignition is
ON to avoid personal injury when clearing
snow and ice from the windshield.NOTICETurn the rain sensor off before washing
the car in an automatic carwash, to avoid
damaging the windshield wipers.

104 Instruments and controls
Activate the rain sensor by lifting the stalk
switch to the AUTO position. The wipers
make one sweep for reference to see how
much water is on the windshield. Thereafter
the sensor compares the amount of water
on the windshield with this reference value.
If the stalk switch is left in the AUTO position
when the engine is switched off, when the
engine is next started it must first be moved
to the 0 or 3 position and then back to AUTO
to reactivate the sensor.
If the system malfunctions, the wipers will
operate at low speed when the stalk switch
is set to the AUTO position and SID will
show:
WashersActivate the washers by pulling the stalk
switch towards the steering wheel.
When the washers are operated, the wipers
will make 3, 4 or 5 sweeps, depending on
how long the washers were kept on. If
the speed of the car is less than 12 mph
(20 km/h), the wipers will make an addi-
tional sweep after roughly 8 seconds.
When the washer fluid level drops below
1 quart (1 liter), the headlight washers (if
equipped) are deactivated. This is in order
to prioritize the windshield. The following
message is displayed on the SID:
Rain sensor malfunc.

154 Starting and drivingThe light comes on in the event of an engine
or gearbox fault (cars with automatic gear-
box), which may cause driveability prob-
lems but that does not affect exhaust emis-
sion. The car can still be driven but perhaps
with limited performance.
Contact a dealer whenever an opportunity
occurs. We recommend that you contact a
Saab dealer.
Limp-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
"Service Engine Light also known as
CHECK ENGINE" indicator light in the
instrument panel will come on (see
page 83). Have the car checked at a work-
shop as soon as possible. We recommend
that you contact a Saab dealer.
Important considerations 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).
NOTICE If the engine sounds strange there is a
malfunction. We recommend that you
contact a Saab dealer immediately.
 The use of fuel with too low an octane
rating can cause serious engine dam-
age.
Limited performance.
NOTICEIf "Service Engine Light also known
as CHECK ENGINE" indicator light warn-
ing light starts to flash (indicating that the
engine is misfiring and the catalytic con-
verter 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 minimum throttle permitted
by the current traffic situation. Have the
car checked as soon as possible. We rec-
ommend that you contact a Saab dealer.NOTICEUse only unleaded gasoline. Leaded gas-
oline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.

173 Starting and driving
All-wheel drive (XWD)3Essentially, the system consists of a PTU
(Power Take off Unit), propeller shaft, RDM
(Rear Drive Module which contains an elec-
tronically controlled plate clutch, final drive
gear and differential) and driveshafts. This
system enhances driving characteristics
and stability. The system is always active
and cannot be deactivated. It works
together with the ESP system and the
engine and transmission control modules.
When driving at a constant speed, approx.
95% of the torque is distributed to the front
wheels and approx. 5% to the rear wheels.
The torque is distributed steplessly and
instantaneously between the front and rear
wheels, depending on the driving condi-
tions. If the car is fitted with eLSD (electron-
ically controlled plate clutch between the
rear wheels), the torque can also be distrib-
uted individually to the relevant rear wheel.For optimum system function, the car’s tires
should not have varying degrees of wear.
When the XWD system requires service,
the following message is shown on the SID:
When the service message is displayed,
the XWD system may have limited func-
tionality (or be completely disabled in
some cases, i.e. the car switches to
front-wheel drive). Contact a workshop
for information. We recommend that you
contact an authorised Saab dealer.
Traction Control
System (TCS)Anti-spin systemHow the system worksThe Traction Control System (TCS) is
designed to prevent wheelspin. This
enables the car to achieve the best possible
grip and, hence, maximum tractive effort,
together with greater stability.
The TCS system uses information from the
ABS system’s wheel speed sensors to
determine whether any wheel is spinning. If
any wheel is spinning, this is reduced on
all-wheel drive cars initially by changing the
torque distribution, secondly by reducing
the engine torque, and thirdly with the aid of
the wheel brakes. On front-wheel drive cars,
wheelspin is reduced initially by reducing
the engine torque, and secondly with the aid
of the wheel brakes. Service XWD.
WARNING
When driving normally, the TCS system
helps to improve the car’s stability, and
driveability under slippery road and
extreme driving conditions. The TCS
must not be regarded as a system to
enable the driver to maintain higher
speeds. The same precautions must be
adopted as normal for safe cornering and
driving on slippery roads.

Electronic Stability
Program ESP
®
Anti-skid system
The ESP
® system employs both the
antilock braking system (ABS) and the trac-
tion control system (TCS). It is a system that
helps the driver to stabilize the car in
unusual circumstances that can otherwise
be more difficult to handle.
How the ESP
® system works
The ESP
® system can help to prevent the
car from skidding by braking one or several
wheels independently of the driver. The
engine output is then also reduced to pre-
vent the driving wheels from spinning. The
car has sensors that measure wheel speed,
yaw rate, lateral acceleration, steering
wheel position and braking pressure. The
values provided by these sensors are used
to calculate the actual direction of the car,
the intentions of the driver and whether the
ESP
® system should be engaged.
If this direction does not agree with that
intended by the driver, calculated from the
steering wheel position, the ESP
® system is
engaged.
The ESP
® system improves the driver’s
chances of retaining control over the car in
a critical situation.
WARNING
When driving normally, the ESP
® system
helps to improve the car’s stability and
maneuverability under slippery road and
extreme driving conditions. The ESP
®
system must not be regarded as a system
to enable the driver to maintain higher
speeds. The same precautions must be
adopted as normal for safe cornering and
driving on slippery roads must be
adopted.
The illustration shows how the system
brakes one or more wheels (and with var-
ying braking force for each wheel) in order
to increase the car’s chances of following
the direction in which the driver wants to
drive.

180 Starting and drivingSaab Parking
Assistance3Saab Parking Assistance
Saab Parking Assistance facilitates parking
and reversing. There are four sensors in the
rear bumper that detect objects up to 6 ft
(1.8 meters) behind the car.
If the car is heavily laden, the system may
falsely indicate that there is an object within
the detection range. This is since the sen-
sors are angled towards the ground when
the car is tail-heavy.The system uses four sensors in the rear
bumper. These emit ultrasound signals that
bounce back to the sensors off any objects
behind the car. The system, however,
cannot always detect small or narrow
objects, such as a post, since the surface
area presented to the car is too small.The system is activated automatically when
reverse is engaged or selected. Audible
confirmation is given and the following text
is shown on the SID:
If a warning message, such as the safety
belt reminder, is shown on the SID when
reverse is engaged, the audible signals
from the parking assistance system will not
be heard since the warning message has
priority.
When the sensors detect an object within
the monitored area, pulses of sound (- - - -)
will be heard. The frequency of these pulses
WARNING
Responsibility always lies with the driver
when reversing.
 The parking assistance system can
facilitate parking and reversing.
 Bear in mind that small objects, such
as a child lying on the ground, and
narrow objects cannot always be
detected by the system.

increases as the car comes closer to the
object.
If you stop the car with reverse gear
engaged, the sound pulse will stop after
2 seconds. The sound pulses will return if
you continue to reverse. If the car rolls for-
ward while reverse is engaged, the system
is silenced.
When the distance to the object is less
than 1 ft. (30 cm), a continuous tone will
be heard.
When an object is approximately 3 ft.
(90 cm) from the car, the sound pulses
change character markedly (frequency
increases). A distance of about 3 ft. (90 cm)
is suitable if you wish to load or unload the
trunk.
If the distance between an object and a
corner sensor does not change for
3 seconds, for example if you are reversing
alongside a wall, the system will switch to
monitoring straight back. The system indi-
cates if the distance to the wall decreases
again.
If a trailer is hitched up and correctly con-
nected to the trailer contact by the towbar,
the system is automatically deactivated.Reversing alongside a wall
If the distance between an object and a
corner sensor does not change for
2 seconds, for example if you are reversing
alongside a wall, the system will switch to
monitoring straight back. The system indi-
cates if the distance to the wall decreases
again.Cars with trailer hitch
If the car has a trailer hitch and its wiring is
correctly connected to the car’s electrical
system, the Saab Parking Assistance auto-
matically compensates for the protrusion of
the towbar.
If a camper or trailer is hitched up and the
trailer hitch wiring is correctly connected to
the car’s electrics, the system is automati-
cally deactivated.
You can temporarily deactivate the Saab
Parking Assistance as follows:
Engage reverse and press the CLR button
on the steering wheel.
The system will be reactivated the next time
you engage reverse.
NOTICEThe sensors must be kept clean to func-
tion well. Ice, snow and dirt can affect
their sensitivity.
Large quantities of snow or dirt covering
the sensors can prevent the parking
assistance system from detecting any
objects.
Do not spray the sensors with a pressure
washer, as this can damage them.
