ACTIVE SAFETY
SYSTEMS
Depending on the version, they can
consist of:
by the anti-lock braking system
(ABS);
electronic stability control (ESC) with
understeering and traction control
system;
driving with a trailer assistance;
emergency brake assistance;
road grip control;
assisted departure on inclines.
ABS (Anti-lock Braking
System)
142) 143) 144) 145)
In case of sharp braking, the ABS
avoids wheel locking, so it manages the
braking distance and maintains vehicle
control.
In these conditions you can carry out
manoeuvres while braking fully.
Moreover, this system optimises the
braking distance, especially on slippery
surfaces (wet roadbed, etc.).
Every time you activate this device, you
know because the brake pedal shakes.
The ABS never improves the "physical"
performance associated with grip
between the wheel and the road. The
rules of the road must be respected
(safety distance between vehicles, etc.).IMPORTANT In an emergency, we
advise you to apply strong, continuous
pressure to the brake pedal. You do not
need to pump it. The ABS will modulate
the force applied to the brakes.
Irregular operation:
andlit on the instrument
panel accompanied by the dedicated
message on the display indicate
deactivation of the ABS, of the ESC
and of the emergency servo brake.
Braking is always guaranteed;
andSTOPlit on the
instrument panel, along with the
dedicated message on the display,
indicates that there is a fault in the
brake system.
In both cases, contact a Fiat
Dealership.
ESC (Electronic Stability
Control) SYSTEM
146) 147)
Electronic stability control ESC
This system helps maintain control of
the vehicle in "critical" driving conditions
(avoiding an obstacle, loss of grip in a
curve, etc.).
Operating principle
A sensor on the steering wheel
recognises the driving trajectory that the
driver set.
Other sensors installed in the vehicle
measure the real trajectory.The system compares the driver's
adherence to the effective trajectory,
correcting it if necessary, braking a few
wheels and/or reducing engine power if
the system was activated and its
warning light
flashes on the
instrument panel.
Understeering control
This system optimises the ESC action
in case of noticeable understeer (loss of
front grip).
Traction Control System
This system limits the drive wheels
slipping and helps control the vehicle
when starting out, accelerating or
decelerating.
Operating principle
Thanks to the sensor in the wheels, the
system measures and compares the
drive wheel rotation speed, detecting
immediately loss of grip. If a wheel
starts sliding, the system intervenes by
braking to re-stabilise the drive that is
compatible with the level of road grip.
The system also acts on the engine
speed, adapting it to wheel road grip,
independently of the driver's use of the
accelerator.
Irregular operation
When the system detects an
operational irregularity, the dedicated
message appears on the display and
the warning lights
andturn
on.
