2005 SAAB 9-5 sensor

74 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 pro-
perly.
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.

82 Instruments and controlsCondensation When the A/C system is running, the intake
air is dehumidified, and the resultant con-
densation is drained off through two outlets
underneath the floor of the car, in the vicinity
of the front doors.
It is therefore perfectly normal for water to
be seen dripping from these outlets when
the car is parked. Greater amounts of con-
densation will result in warmer, more humid
ambient air.
Formation of ice and mist in
extremes of weather It is only in the most extreme conditions that
icing and misting of window glass are likely
to be a problem, e.g. in torrential rain or
severe cold coupled with high relative humi-
dity, or when passengers are perspiring
heavily or wearing wet clothes.
The following measures are recommended
if such problems should occur:
1 Select AUTO and 70°
F (21°C) for both
temperature zones.
2 Select Defroster.
If this is not enough...
3 Increase the fan speed.
If this is not enough...
4 Select a higher temperature.
The following measures are recommended
if the occupants feel that it is cold and drafty
in the car:
1 Make sure that all the air vents are fully
open, including the center rear vent.
If this is not enough...
2 Direct the air flow away from the body
(but not towards the interior temperature
sensor).
If this is not enough...
3 Raise the temperature setting a degree
or two. If this is not enough...
4 Lower the fan speed.

111 Interior equipment and trunk
Opening a garage doorTo 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(accessory)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-facing. They also activate and deacti-
vate the auto dimming feature on door mir-
rors.
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 dar-
kening 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.

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 an authorized Saab
dealer as soon as possible.
 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
an authorized Saab dealer for advice.
 Never park the car on dry grass or other
combustible material. The catalytic con-
verter gets very hot and could therefore
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
gasoline 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.

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 redu-
ces 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 simultan-
eously, and steer the car to safety.

155 Starting and driving
Electronic Stability
Program (ESP)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 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.
ESP improves the driver’s chances of
retaining control over the car in critical situ-
ations.
To ensure that the system works as
designed, the dimensions of all four tires
must be the same.
WARNING
When driving normally, ESP 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.

Saab Parking
Assistance(if equipped)The 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 monito-
red 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.

178 Starting and drivingWhen 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
CLEAR button on the SID when the display
shows "PARK ASSIST", until the display
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 SID button briefly will not disen-
gage the system, the display will simply
show the previously selected function.
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 CLEAR button for
1.5 seconds.
If the text "PARK ASSIST FAILURE" is dis-
played on the SID, have the system
checked by 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.
