ABS, EBD and HBA
systems
The vehicle is equipped with ABS
(Anti-lock Braking System) and EBD
(Electronic Brake force Distribution)
systems, which enhance the braking
system performance by means of the
ABS system sensors and ECU.
In the event of emergency braking
or braking on slippery road surfaces
(e.g. snow, ice etc.) the ABS, in
combination 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 uses an electronic control
unit that processes the signals coming
from 4 sensors fi tted on the 4 wheels.
When a wheel tends to lock, the
sensor warns the ECU, which activates
an electro-hydraulic unit that
modulates the pressure applied to
the brake calipers; the driver will feel
a “pulsing” sensation on the brake
pedal which is completely normal.
To complete the action of the braking
assistance systems, the vehicle is
equipped with HBA (Hydraulic Brake
Assistance) device, which helps the
driver during emergency braking.
In the event of a critical situation,
where the vehicle must stop in
the shortest possible distance,
the driver usually depresses the
brake pedal quickly, but often not
strongly enough: this increases the
braking distance. This system has
been designed to solve this problem
and acts by applying the maximum
braking force during emergency
braking, in order to stop the vehicle in
the shortest possible distance.
The system recognises the emergency
condition by analysing some
parameters, such as the pressure on
the brake servo, the wheel speed and
activation of the third stop. The ABS
control unit cross-checks this data and
substitutes the driver by activating
the braking system’s full power and so
ensures optimal braking performance
in the shortest possible distance.
In the event of a failure the system
will be deactivated, but this will not
affect the effi ciency of the standard
braking system.
The failure will be indicated by the
illumination of the amber warning
light with the letters ABS
on the
instrument panel.
In this case we recommend that you
contact the nearest Centre of the
Maserati Service Network in order to
identify the fault as soon as possible,
by means of the system self-diagnostic
function.
The vehicle 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 considerably increases
the safety levels, it is
essential to always drive with the
greatest care when the road surface is
wet, covered with snow or ice.
