The antilock braking and anti-slip regulation
systems (BOSCH 5.7 ABS with ASR) modulate brake pressure sent to
the wheels to prevent loss of grip under all tyre and road surface
conditions by cutting in automatically whenever one or both drive
wheels begin to slip.The ASR system increases vehicle stability
and active safety by controlling drive wheel slip. If slip is caused
by excessive power transmission, it cuts in to reduce engine power through
communication with the engine management control unit. if slip is
detected at a single wheel, the system cuts in to brake the slipping
wheel by acting on the modulation solenoid.ASR comes on automatically whenever the
engine is started. The system can be deactivated by operating a
button on the central console. When the system is off, a led on
the button comes on at the same time as a warning light on the control
panel. The warning light flashes when the system
cuts in to notifiy the driver that the ASR system has cut in due
to road surface grip conditions.The warning light comes in in fixed mode
when the control unit detects an error in the ASR function.
