2005 SAAB 9-5 brake sensor

153 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 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.

237 Car care and technical information
Washing the carWash your car frequently. To facilitate clea-
ning, a suitable detergent can be added to
the water, which should be lukewarm. Saab
offers a full line of car care products, inclu-
ding car wash, for the care of your vehicle.
See your dealer for available products or
visit www.saabcatalog.com (U.S. residents
only).
Do not use a pressure washer at close
range on stone chip damage, scratches or
other damage to the paintwork. The paint
can otherwise start to flake.
Remove any bird droppings without delay,
as these can discolor the paintwork and
prove difficult to polish out.
Use a soft cloth moistened with methyl alco-
hol to remove splashes of tar or asphalt. Do
not use strong cleaners, as these can dry
out the paintwork.
The underside of the car also needs wash-
ing regularly, and this should be done extra
thoroughly at the end of winter. Clean the
underside of the car by hand if the car is usu-
ally washed in an automatic car wash wit-
hout special facilities for underbody clea-
ning.
Never wash or leave the car to dry in the
sun, but wipe it dry with a chamois leather
immediately after washing to avoid smears
and streaks.
Clean the window glass inside and out using
a high quality window cleaner. This is parti-
cularly important when the car is new, as
upholstery and trim have a tendency to
sweat a little at first.
Keep the glass well cleaned, as this helps to
prevent misting.

NOTICEAvoid using any alcohol-based cleaners
on the front and rear light clusters, as
these can cause cracking of the lenses.
NOTICE The door mirrors must be fully
retracted before the car enters an
automatic car wash.
 Remove fixed antennas, e.g. for
mobile phone, before putting car
through an automatic car wash.
 Try your brakes on leaving a car wash.
Wet brake discs may reduce the
performance of the brakes.
 Cars with Saab Parking Assistance:
Do not spray the sensors or closer
than 20 cm to the sensors with a pres-
sure washer, as this can damage
them.
