ABS Brake System
(anti-lock brake system)
Safety notes!
In spite of the advantages of ABS, it is still the
driver's responsibility to adapt his driving style and
manoeuvres in line with road and weather condi-
tions, as well as the traffic situation.
The increased safety that is provided should not
induce you to take greater risks with your safety.
The limits set by the physics of driving cannot be
overcome, even with ABS.
Risks of accident due to inappropriate speed
cannot be reduced by ABS.
ABS ensures
Full steering control
– The vehicle remains steerable
Good driving stability
– No skidding due to locked wheels
Optimum braking distance
– Shorter stopping distances in most cases
Prevention of wheel locking
– No flat spots on the tyres
Function
The decisive advantage of ABS lies in the driving
stability and manoeuvrability of the vehicle in
hazardous situations.
The ABS prevents locking of the wheels during full
braking, on almost all road surfaces, until shortly
before the vehicle stops.
The ABS begins to control the braking process as
soon as a wheel shows a tendency to lock.
This controlled braking process is comparable
with extremely rapid cadence braking.
The pulsating brake pedal and a “juddering noise”
warn the driver to adapt his driving speed to the
road conditions.
f
If full braking should be necessary, press the
brake pedal all the way down throughout the
entire braking procedure, regardless of the
pulsating pedals. Do not ease up on pressure
applied to the pedal.
