2009 SAAB 9-5 sensor

78 Instruments and controlsWhen the engine has been switched off,
the control stalk must be moved to posi-
tion 0 and back to position 1 to reactivate
the sensor.
Set the sensitivity using the control on the
wiper stalk (the same control as used for
wiper delay on cars not fitted with a rain sen-
sor). The sensor has three sensitivity set-
tings. It is most sensitive when in the upper-
most position (1). When a higher degree of
sensitivity is selected, the wipers make one
sweep of the windshield for reference.
The rain sensor has a daylight and a night
time mode. The sensor measures the
amount of available light and automatically
selects the appropriate mode. The sensor is
more sensitive at night. The function of the
rain sensor is impaired by dry snow.
Rear-window wiper
(SportCombi)3The rear-window wiper and washer are
operated with the same stalk switch as used
for washing and wiping the windshield and
headlights.
This stalk has two additional switches,
ON/OFF and .
The ON position provides intermittent wip-
ing.
The position provides washing and
wiping. After a few sweeps the wiper stops
or reverts to intermittent wiping, if this has
been chosen. About 15 seconds after com-
pletion of the washing/wiping of the rear
window, the wiper makes a single sweep to
wipe away any remaining washer fluid.
A spring-loaded position between the OFF
and ON positions allows for a single sweep
of the rear-window wiper.
Intermittent wiping of the rear window
occurs when reverse gear is engaged if the
windshield wipers are in position 1, 2 or 3,
see page 77.

80 Instruments and controls
The system has five sensors:
 Outdoor temperature sensor
 Interior temperature sensor
 Sun sensor (mounted on top of the fascia)
 Two blended-air temperature sensors
(mounted inside the front floor vents)
Note: If anything is placed over the sun sen-
sor, the ACC system will not function prop-
erly.
Panel vents The panel vents swivel in all directions so
that air can be directed as desired. In winter,
for instance, the outer vents can be directed
onto the door windows for enhanced
demisting.
The flow of air through the panel vents can
be controlled individually for each vent by
means of the adjacent control. The climate
control system works best if the panel vents
are open. If you find the air cold or that it is
drafty, start by directing the air away from
the body. If the center vent is aimed up, it will
cool the interior temperature sensor and
you may need to adjust ACC up or down,
depending upon temperature desired.

121 Interior equipment and trunk
Opening a garage door
To operate, simply press and release the
programmed button. Activation will now
occur for the trained device (i.e. garage door
opener, gate operator, security system,
entry door lock, home/office lighting, etc.).
For convenience, the hand-held transmitter
of the device may also be used at any time.
Rearview auto-dimming
mirrors
3
The autodimming is activated and deacti-
vated with a short push on button 2.
If the mirror is equipped with Garage Door
Opener (option) the letter 1 is displayed on
compass bearing display briefly when auto
dimming is activated. When deactivating
the letter 0 is displayed.
The interior rearview mirror has two sen-
sors, one forward-facing and one rear-fac-
ing. They also activate and deactivate the
auto dimming feature on door mirrors.
The system is activated when the for-
ward-facing sensor detects that it is dark
outside and the rear-facing sensor detects.
For example, if the car following has not
dimmed its headlights. The rearview mirrors
are then darkened to prevent the strong light
source from dazzling the driver. This dark-
ening is stepless.
The mirrors return to their normal states
when the strong light source diminishes.
The auto dimming function can be turned
OFF with the switch on the lower edge of the
rear-view mirror.
NOTE
Towing a trailer can cause the system to
malfunction, as the rear-facing sensor may
sense light from the trailer.
NOTICESwitch off the power supply to the garage
door or gate (or park the car beyond the
range of the remote control) while pro-
gramming using the "cycling" method to
prevent damaging the electrical motor.

145 Starting and driving
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 (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 a workshop as soon as
possible. We recommend that you
contact an authorized Saab dealer.  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
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 five minutes to give it time
to settle and run smoothly. If, after this
time, the engine still fails to run properly,
turn off the engine and get in touch with a
workshop for advice. We recommend that
you contact an authorized Saab dealer.  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 jump start the car when the engine
is already up to normal temperature, the
engine must start to run on all cylinders.
Stop jump-starting if the engine fails to
start immediately.
Failure to follow these directions could
result in the catalytic converter and associ-
ated components being damaged, and
could represent a breach of the warranty
conditions.
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.
NOTICEIf the car runs out of fuel, it is possible for
air to get into the fuel system. If this
happens, the catalytic converter may
overheat and be damaged.

161 Starting and driving

ABS brakes
ABS (antilock braking system) modulates
the brake pressure to the respective
wheels. Wheel sensors detect if a wheel is
about to lock, and the control module
reduces the pressure to that wheel and then
increases it once more until the tendency is
detected again.
The brake system is equipped with an Elec-
tronic Brake-force Distribution device
(EBD), which distributes the brake pressure
between the front and rear wheels, in such
a way as to achieve optimum braking perfor-
mance irrespective of the car’s speed and
load.
WARNING
 It is prudent to try your brakes from
time to time, especially when driving in
heavy rain, through water collected on
the road, in snow, on a wet road sur-
face or in salty slush. In such condi-
tions, the brakes may take longer than
normal to take effect. To rectify this,
touch the brake pedal periodically to
dry the brakes out.
 The same applies after the car has
been washed or when the weather is
very humid.
 Avoid parking the car with wet brakes.
Before parking, and if the traffic condi-
tions allow, brake quite heavily so that
the brake discs and pads warm up and
dry.
 The brakes are power assisted and it
should be kept in mind that the servo
unit only provides the power assis-
tance when the engine is running.
 The brake pressure required when the
engine is off,(e.g. when the car is
being towed) is roughly four times the
normal pedal force required. The
pedal also feels hard and unre-
sponsive.
WARNING
 The additional safety afforded by the
ABS system is not designed to allow
drivers to drive faster but to make
normal driving safer.
 To stop as quickly as possible, without
loss of directional stability, whether
the road surface is dry, wet or slippery,
press the brake pedal down hard-
without letting up (do not pump the
pedal), declutching simulta-
neously, and steer the car to safety.

163 Starting and driving
Electronic Stability
Program (ESP
®)
The system employs both the antilock brak-
ing system (ABS) and the traction control
system (TCS). It is a system that helps the
driver to stabilize the car in unusual circum-
stances that would otherwise be more diffi-
cult to handle.
How the ESP
® system works
The 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 prevent the
driving wheels from spinning. The car has
sensors that measure wheel speed, yaw
acceleration, lateral acceleration, steering
wheel position and braking pressure. The
values provided by these sensors are used
to calculate the actual direction of the car. If
this direction does not agree with that
intended by the driver, calculated from the
steering wheel position, the ESP
® is
engaged.
The ESP
® system improves the driver’s
chances of retaining control over the car in
critical situations.
To ensure that the system works as
designed, the dimensions of all four tires
must be the same.
WARNING
When driving normally, the ESP
® system
will help to improve the stability of the car.
This does not mean that car can be driven
faster. The same care and prudence as
normally applied should be displayed on
cornering and when driving on slippery
roads.
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.

168 Starting and drivingSaab Parking
Assistance3The parking aid system facilitates parking
and reversing. There are four sensors in
the rear bumper that detect objects up to
6 feet (1.8 metres) behind the car.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 or objects that do not reflect ultra-
sound back towards the car, such as pipes,
or the corner of a house or rectangular post.The system is activated automatically when
reverse is engaged or selected. When the
sensors detect an object within the moni-
tored area, the SID will display the text
"PARK ASSIST" and pulses of sound
(- - - - -) will be heard. The frequency of the
pulses increases as the car comes closer to
the object.
When the distance to the object is less
than 12 in. (30 cm), a continuous tone
will be heard.
WARNING
Responsibility always lies with the driver
when reversing.
 Saab Parking Assistance can facilitate
reversing at low speeds, such as when
reverse parking.
 Bear in mind that small and/or narrow
objects cannot always be detected by
the system.

169 Starting and driving
When an object is approximately 3 feet
(90 cm) from the car, the sound pulses
change character markedly. A distance of
about 3 feet (90 cm) is suitable if you wish
to load or unload the luggage compartment.
If the distance between an object and the
corner sensors does not change for three
seconds, e.g. if you are reversing alongside
a wall, the system will switch to monitoring
straight back. The system indicates if the
distance to the wall decreases again.
The system can be disengaged for when
driving with a trailer. Press and hold the CLR
button on the steering wheel when the dis-
play shows "PARK ASSIST", until the dis-
play shows "PARK ASSIST OFF". The
system is re-engaged in the same way. The
system is also always activated when the
ignition key is turned to ON. Pressing a steering wheel button briefly will
not disengage the system, the display will
simply show the previously selected func-
tion.
Ice, snow and dirt can affect the sensitivity
of the sensors. In such cases a continuous
tone will sound warning the driver that the
system cannot measure the distance to an
object. You can turn the system off by press-
ing and holding the CLR button for
1.5 seconds.
If the text "PARK ASSIST FAILURE" is dis-
played on the SID, have the system
checked by a workshop. We recommend
that you contact an authorized Saab dealer.NOTICEReverse slowly so that you have time to
stop the car when the continuous tone is
heard at approx. 12 in. (30 cm).
NOTICETo function well, the sensors must be kept
clean. Ice snow and dirt can affect their
sensitivity.
Do not spray the sensors or closer than
8 in. (20 cm) to the sensors with a pres-
sure washer, as this could damage them.
