Electronic Stability
Program (ESP)Anti-skid system
(Certain variants)
The Electronic Stability Program employs
both the antilock braking system (ABS) and
the traction control system (TCS). It is a
system that helps the driver to stabilize the
car in unusual circumstances that can oth-
erwise be difficult to handle.
How the ESP system worksThe Electronic Stability Program 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 prevent the driving wheels from
spinning. The car has sensors that measure
wheel speed, yaw rate, lateral acceleration,
steering wheel position and braking pres-
sure. 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 should be engaged.
If this direction does not agree with that
intended by the driver, calculated from the
steering wheel position, the ESP is
engaged.
The ESP improves the driver’s chances
of retaining control over the car in critical
situations.
WARNING
When driving normally, the ESP system
helps to improve the car’s directional
stability. The ESP must not be regarded
as a system to enable the driver to main-
tain higher speeds. The same precau-
tions must be adopted as normal for safe
cornering and driving on slippery roads
must be adopted.

brakes on one or several wheels to help

176 Starting and drivingSaab Parking
AssistanceSaab Parking Assistance
(option)
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 seatbelt
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
increases as the car comes closer to the
object.
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.

177 Starting and driving
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 tow bar,
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 tow bar.
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 CLEAR
button on the SID control panel.
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.

214 Car careXenon headlight, dipped beam(certain variants only)
Xenon headlights produce roughly two times as much light as halo-
gen bulbs and have a significantly longer service life.
The lamp units consist of a gas discharge lamp containing xenon.
When the lights are switched on a very high voltage activates the
xenon gas. The lamps soon reach full intensity.
Cars with xenon headlights have automatic levelling. The levelling
system is comprised of two sensors, one on the front suspension
and one on the rear suspension, and a control unit by the engine bay
fuse box. Headlight alignment is adjusted automatically to the car’s
load to prevent dazzling drivers in oncoming traffic.
If a fault is detected in the system, the following message will be dis-
played on the SID:
WARNING
Xenon headlights are high tension. All work on xenon headlights,
including changing bulbs, must be carried out by dealer person-
nel.
Headlight levelling
malfunction.
Contact Saab dealer.
Contact a Saab dealer to have a xenon
headlight changed
