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.
