Active Safety Systems - Fiat 500 Owner's Handbook Manual

ACTIVE SAFETY
SYSTEMS
The vehicle has the following active
safety systems:
ABS (Anti-lock Braking System);
EBD (Electronic Brake force
Distribution);
MSR (Motor Schleppmoment
Regelung);
ESC (Electronic Stability Control);
HH (Hill Holder);
ASR (Antislip Regulation);
HBA (Hydraulic Brake Assist);
For the operation of the systems, see
the following description.
ABS (Anti-lock Braking
System)
This system, which is an integral part of
the braking system, prevents one or
more wheels from locking and slipping
in any road surface condition,
irrespective of the intensity of the
braking action, ensuring that the car
can be controlled even during
emergency braking thus optimising
stopping distances.
The system intervenes during braking
when the wheels are about to lock,
typically in emergency braking or
low-grip conditions, when locking may
be more frequent.

The system also improves control and
stability of the car when braking on a
surface where the grip of the left and
right wheels varies, or on corners.
System intervention
A slight pulsing of the brake pedal and
noise indicates the intervention of the
ABS: this is completely normal when
the system intervenes.

EBD (Electronic
Brakeforce Distribution)
SYSTEM
This system (which cannot be
deactivated) recognises emergency
braking conditions according to the
speed of operation of the brake pedal
and provides an additional hydraulic
braking pressure to support that
provided by the driver. This allows
faster and more powerful operation of
the braking system.
MSR (Motor
Schleppmoment
Regelung) SYSTEM
The MSR system is an integral part of
the ABS, that intervenes, if there is a
sudden change to a lower gear,
restoring torque to the engine, thereby
preventing excessive drive at the drive
wheels which, especially in poor grip
conditions, could lead to a loss in
stability of the vehicle.
ESC (Electronic Stability
Control) SYSTEM
This is an electronic system that
controls vehicle stability in the event of
tyre grip loss, helping maintain
directional control.
The system is capable of recognising
potentially dangerous situations in
terms of the stability and intervenes
automatically on the brakes in a
differentiated manner for the four
wheels in order to provide a stabilising
torque.
The ESC system switches on
automatically when the engine is
started and cannot be switched off.
System intervention
This is indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the car is
in critical stability and grip conditions.
