Starting and driving

Braking

To avoid the brakes becoming overheated,
(e.g. when negotiating long descents with a
drop of several hundred feet), select a low
gear to use the braking effect of the engine.
If the car has automatic transmission, move
the selector lever to position 1 or 2.
When driving fast, you can help to prolong
the life of the brakes by thinking ahead and
braking harder for short periods, rather than
braking more moderately over long
stretches.

Brake pad wear indicators

The outboard brake pads on the front
wheels incorporate pad-wear indicators.
When the lining is down to 3 mm, the pad
will produce a screeching, squealing or
scraping noise when the brakes are applied.
New pads should be fitted without delay.
Brake pads should only be replaced by
an authorized Saab dealer.

To ensure optimum brake performance,
it is recommended that you use only
Saab original brake pads.

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.
The ABS system has a built-in diagnostic
function which will switch on the Anti-lock
brake warning li
ght if a fault is detected in
the system (see page 48).

WARNING

• It is prudent to try your brakes from

time to time, especially when driving in
heavy rain, on roads with a lot of sur-
face water, or in snow or slush. In such
conditions, the brakes may take
longer than normal to take effect. To
rectify this, touch the brake pedal peri-
odically to dry the brakes out.
The same applies after the car has
been washed or when the weather is
very humid.

• 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 on
tow) is roughly four times the normal
pedal force required. The pedal also
feels hard and unresponsive.

• We advise against using wheels with

open wheel covers in winter, as the
brake components are then more
exposed both to slush, road salt and
grit.

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,
declutching
simultaneously, and steer the car to
safety.
