ABS and EBD systems

The vehicle is equipped with ABS (Anti-
lock Brake System) and EBD (Electronic
Brake force Distribution) systems
which, by means of the ABS system
sensors and the ECU, improve the
braking system's performance.
In the event of an emergency stop or
braking on slippery surfaces (e.g.
snowy or icy roadbeds), the ABS,
together with the standard braking
system, allows the driver to apply
maximum braking force without
causing the wheels to lock and
consequently losing control of the
vehicle.
The system is based on an electronic
control unit that processes the signals
coming from 4 sensors fitted on the 4
wheels.
When a wheel tends to lock, the sensor
warns the unit which, in turn, request
to an electro-hydraulic unit to
intervene by modulating the pressure
exerted on the brake calipers; the
driver will perceive a "pulsation" on
the brake pedal which is completely
normal.
In the event of a failure, the system will
be deactivated, but this will not affect
the efficiency of the standard braking
system.
The failure will be indicated through
the lighting up of the red warning
light with the letters ABS on the
instrument panel.
In this case, we recommend you
contact the nearest Maserati Service
Network centre, which, thanks to the
self-diagnostics system the vehicle is
equipped with, will be able to identify
the problem immediately.
The vehicles must be
equipped only with wheels,
tyres and brake pads of the
type and make approved by the
Factory for this model.
Despite the fact that this
device makes a considerable
contribution to safety, it is still
essential to drive particularly carefully
when the road surface is wet, covered
with snow or ice.
The vehicle is equipped with
an EBD (Electronic Brake-force
Distribution) system). With
the engine on, if the warning light
illuminates accompanied by a specific
message on the display it indicates a
fault in the EBD system. In this case,
sharp braking can cause early locking
of the rear wheels and possible side
skidding. Drive with the greatest care
and have the system immediately
checked by the nearest Centre of the
Maserati Service Network.
