Abs - Lancia Lybra Owner's Handbook Manual

Contact a Lancia Dealer-
ship as soon as possible if
U
the warning light either
does not come on when the key is
turned to MAR or comes on, with
fixed or flashing light, when trav-
elling.
IMPORTANT After eliminating the
problem, your Lancia Dealership
will run a bench test to fully check the
system. In some cases, a long road test
may be required.

ABS

GENERAL
The ABS (wheel anti-locking) sys-
tem prevents wheel locking and con-
sequent slipping in all road surface
conditions. This ensures greater con-
trol, as it is possible to steering and
brake at the same time, and reduces
braking space.
If the road surface conditions de-
crease the friction coefficient (i.e. due
to the presence of water, ice, snow,
etc.), a wheel may slip. Furthermore,
a wheel which is not locked can ab-
sorb the lateral forces exerted by the
tyre which preventing steering.
The car is equipped with an elec-
tronic brake force distributor - called
EBD - which, by means of the ABS
electronic control unit and sensors, in-
creases the brake system perfor-
mance.
OPERATION
The electronic control unit receives
and processes the signals from the
brake pedal and the four sensors on
the wheels. It consequently controls
the hydraulic system so to decrease,
hold or increase the pressure in the
circuit and prevent locking.
IMPORTANT A slight pulsation of
the brake pedal may be felt when the
ABS system comes into play.
The car is fitted with an
electronic braking device
(EBD). The > and x
warning lights come on at the
same time when the engine is run-
ning to indicate that there is an
EBD system failure. In this case vi-
olent braking may be accompa-
nied by early rear wheel locking
with the possibility of skidding.
Drive the car extremely carefully
to the nearest Lancia Dealership to
have the system checked.
