In this case, the rear wheels may
suddenly lock and the vehicle may
swerve when braking sharply. Drive
carefully to the nearest Fiat
Dealership to have the system
checked.

BRAKE ASSIST
(integrated ESP
emergency braking
assistance)
(for versions/markets, where
provided)
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.
Brake Assist is deactivated on the
versions equipped with ESP, in
the event of ESP system failure
(indicated by the warning light
coming on together with the
message in the multifunction display,
where provided).

WARNING
53) When the ABS cuts in and you
feel the brake pedal pulsating,
do not raise your foot, but keep it
pressed; in doing so you will stop
in the shortest amount of space
possible depending on the current
road conditions.
54) If the ABS intervenes, it is a sign
that the grip between tyre and the
road surface has reached the
limit: you must slow down to
adapt the speed to the road grip
available.
55) The ABS exploits the grip
available to the full, but it cannot
improve it. Therefore, you should
take great care when driving on
slippery surfaces, without taking
unnecessary risks.
56) If only the warning light
lights up in the instrument panel
(with a message in the display
on some versions), stop the
vehicle immediately and contact
the nearest Fiat Dealership. Fluid
leaking from the hydraulic system
will compromise the operation
of the braking system, whether it
is of the conventional type or
with ABS.
57) When the ABS cuts in and you
feel the brake pedal pulsating,
do not raise your foot, but keep it
pressed; in doing so you will stop
in the shortest amount of space
possible depending on the current
road conditions.
