Erm System; Tsc System; System Intervention - Fiat 500X Owner's Handbook Manual

In critical situations (braking on surfaces
with different grip conditions), through
the DST function the ESC system
controls the steering to implement an
additional torque contribution on the
steering wheel, to suggest the most
correct manoeuvre to the driver.
The coordinated action of the brakes
and steering increases the sensation of
safety and control of the vehicle.
53)
ERM (Electronic Rollover
Mitigation) SYSTEM
The system monitors the tendency of
the wheels to rise from the ground if the
driver performs extreme manoeuvres
like quick steering to avoid an obstacle,
especially in poor road conditions.
If these conditions occur, the system
intervenes on the brakes and engine
power to reduce the possibility that the
wheels are raised from the ground. It is
not possible to avoid tendency to roll
over if the phenomenon is due to
reasons such as driving on high side
gradients, collision with objects or other
vehicles.
54)
TSC (Trailer Sway
Control) SYSTEM
The system employs a series of sensors
located on the vehicle to identify
excessive swerving of the trailer and
take the necessary precautions to
eliminate it.
To counteract the effect of trailer sway,
the system can reduce the engine
power and intervene on the wheels
involved. The TSC system activates
automatically once excessive sway of
the trailer is detected.

System intervention

When the system is active, the
warning light flashes on the
instrument panel, the engine power is
reduced and braking can be felt on the
individual wheels, following the attempt
to eliminate the swerving of the trailer.

WARNING
31) When the ABS intervenes and you feel
the brake pedal pulsating, do not reduce
the pressure, but hold it down firmly and
confidently; in doing so you will brake in the
shortest distance possible, depending on
the current road conditions.
32) To obtain the maximum efficiency of
the braking system, a bedding-in period of
about 500 km is needed: during this period
it is better to avoid sharp, repeated and
prolonged braking.
33) If the ABS intervenes, this indicates
that the grip of the tyres on the road is
nearing its limit: you must slow down to a
speed compatible with the available grip.
34) The ABS cannot overrule the natural
laws of physics, and cannot increase the
grip available according to the condition of
the road.
35) The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.
36) The capability of the ABS must never
be tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
37) For the correct operation of the ABS,
the tyres must of necessity be the same
make and type on all wheels, in perfect
condition and, above all, of the prescribed
type and dimensions.
38) The ESC system cannot alter the
natural laws of physics, and cannot
increase grip, which depends on the
condition of the road.
39) The ESC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
40) The capability of the ESC system must
never be tested irresponsibly and
dangerously, in such a way as to
compromise personal safety and the safety
of others.
