A
ACTIVE AND PASSIVE SAFETY
ACTIVATION
The
VDC
and
ASR
systems are integrated in one
single function and are automatically activated
every time the engine is started; they can be
deactivated by pressing the button
A
for about
1 second.
Press the button
A once again to reactivate the
systems.
The amber colour warning light
on the
instrument panel flashes during all the operating
phases.
FAULT INDICATORS
In the event of a malfunction, the system
is automatically disabled and cannot be
reactivated. This condition is signalled while
driving by the amber symbol
on the display
that illuminates together with the message “ASR
failure - Go to workshop”.
MSR FUNCTION (ENGINE
BRAKING TORQUE
ADJUSTMENT)
The ASR system also controls the engine braking
torque when the accelerator pedal is released
under low grip conditions (e.g., snow, ice etc.):
in these conditions, the high braking torque of
the engine may cause instability of the vehicle.
The system, using the same sensors as the ABS
system, detects the skidding of one or both
of the driving wheels when the accelerator is
released and opens the motor-driven throttle for
the engine fuel system. This reduces the braking
torque and resets the maximum grip conditions
for the driving wheels.
WARNING:
However, the maximum deceleration
that can be obtained with the engine brake still
depends on the tyre grip on the road. Snow or ice
obviously reduce grip values.
