Brake System; Electronic Brake Control System; Four-Wheel Anti-Lock Brake System (Abs) - Fiat 2015 500e Owner's Manual

BRAKE SYSTEM

In the event regenerative braking or power assist is lost
for any reason the brakes will still function. The effort
required to brake the vehicle will be significantly more
than that required with the power system operating.
If either the front or rear hydraulic system loses normal
capability, the remaining system will still function with
some loss of braking effectiveness. This will be evident by
increased pedal travel during application, greater pedal
force required to slow or stop, and activation of the Brake
Warning Light and the ABS Warning Light during brake
use.

ELECTRONIC BRAKE CONTROL SYSTEM

Your vehicle is equipped with a advanced electronic
brake control system that includes the Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Traction Con-
trol System (TCS), and Electronic Stability Control (ESC).
All systems work together to enhance vehicle stability
and control in various driving conditions and are com-
monly referred to as ESC.

Four-Wheel Anti-Lock Brake System (ABS)

The Four-Wheel ABS is designed to aid the driver in
maintaining vehicle control under adverse braking con-
ditions. The system operates with a separate computer to
modulate hydraulic pressure, to prevent wheel lock-up
and to help avoid skidding on slippery surfaces.
The system's pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The ABS includes an amber ABS Warning Light. When
the light is illuminated, the ABS is not functioning. The
system reverts to standard non-anti-lock brakes. Turning
