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, are designed to
improve the braking system's
performance.
In the event of an emergency stop or
braking on slippery surfaces (e.g.,
snowy or icy roadways), the ABS,
together with the standard braking
system, is designed to allow 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, requests
an electro-hydraulic unit to intervene
by modulating the pressure exerted on
the brake; 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 illumination of the red warning
light with the letters ABS on the
instrument panel.
In this case, we recommend you
contact your local Authorized Maserati
Dealer which, thanks to the self-
diagnostics system the vehicle is
equipped with, should be able to
quickly identify the problem.
The vehicles must be
equipped only with wheels,
tires and brake pads of the
type and make approved by Maserati
S.p.A. for this model.
Despite the fact that this
device makes a considerable
contribution to safety, it is still
essential to drive carefully, especially
when the road surface is wet, covered
with snow or ice.
The vehicle is equipped with
an Electronic Brake force
Distributor (EBD). The
illumination of the warning light
"BRAKE" with the engine running
indicates a malfunction in the EBD
system; in this case, sharp braking
may cause an early locking of the rear
wheels, and the vehicle may skid.
Drive with the greatest care and have
the system immediately checked by
the nearest Authorized Maserati
Dealer.
