brake sensor Alfa Romeo Giulietta 2014 Owner's Manual

ESC SYSTEM
IN BRIEF
The ESC system improves the
directional control and stability of the
car in various driving conditions.
The ESC system corrects the car’s
understeer and oversteer, distributing
the brake force on the appropriate
wheels. The torque supplied by
the engine can also be reduced in
order to maintain control of the car.
30) 31) 32) 33) 34)
The ESC system uses sensors installed
on the car to determine the trajectory
that the driver intends to follow and
compares it with the car’s effective
trajectory. When the real trajectory
deviates from the desired trajectory, the
ESC system intervenes to counter the
car’s understeer or oversteer.
❒Oversteer: occurs when the car is
turning more than it should according
to the angle of the steering wheel.
❒Understeer: occurs when the car is
turning less than it should according
to the angle of the steering wheel.The ESC system also includes the
following systems:
❒EBD
❒ABS
❒CBC
❒ASR
❒HILL HOLDER
❒HBA
❒MSR
❒DST
❒“ELECTRONIC Q2” (“E-Q2”)
❒"PRE-FILL" (RAB - Ready Alert
Brake)
SYSTEM ACTIVATION
The ESC system switches on
automatically when the engine is
started and cannot be switched off.
SYSTEM INTERVENTION
This is indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the car is
in critical stability and grip conditions.EBD SYSTEM
The EBD system is an integral part of
the ESC system and intervenes during
braking, distributing the brake force
optimally between front and rear
wheels.
This guarantees greater braking stability
for the car, preventing sudden locking
of the rear wheels and the consequent
instability of the car.
ABS
This system, which is an integral part of
the braking system, prevents one or
more wheels from locking and slipping
in all road surface conditions,
irrespective of the intensity of the
braking action, ensuring that the car
can be controlled even during
emergency braking and optimising
stopping distances.
The system intervenes when braking
and the wheels are about to lock,
typically in emergency braking or
low-grip conditions, when locking may
be more frequent.
The system also improves control and
stability of the car when braking on a
surface where the grip of the left and
right wheels varies, or on corners.

IMPORTANT The volume of the
acoustic signal can be adjusted through
the option "Warning volume" of the
Setup menu (see paragraph “Menu
Items” in the “Knowing the instrument
panel” section).
OPERATION WITH
TRAILER
Parking sensor operation is deactivated
automatically when the trailer electric
cable plug is fitted into the car tow
hook socket.
11)
The sensors are automatically
reactivated when the trailer's cable plug
is removed.
59) 60)
GENERAL WARNINGS
During parking manoeuvres, pay the
utmost attention to any obstacles that
could be located above or below the
sensors.
Objects located near the rear of the car
are not detected under certain
circumstances and could therefore
cause damage to the car or be
damaged.
The following conditions may influence
the performance of the parking sensor
system:❒reduced sensor sensitivity and a
reduction in the parking assistance
system performance could be due to
the presence on the surface of the
sensor of: ice, snow, mud, thick paint
❒the sensors may detect a non-
existent obstacle (echo interference)
due to mechanical interference, for
example when washing the car,
in rain (strong wind), hail;
❒The signals sent by the sensors can
also be altered by the presence of
ultrasonic systems (e.g. pneumatic
brake systems or pneumatic drills)
near the vehicle.
❒sensor performance can also be
influenced by the position of the
sensors. For example by a change in
the ride setting (caused by the wear
of the shock absorbers, suspension),
overloading the vehicle and carrying
out specific tuning operations that
require the vehicle to be lowered;
❒The detection of obstacles at the top
part of the car may not be
guaranteed because the system
detects obstacles that could cause
an impact with the car in the bottom
part.
IMPORTANT
11) The sensors must be clean of
mud, dirt, snow and ice in order
for the system to work. Be careful
not to scratch or damage the
sensors while cleaning them.
Avoid using dry, rough or hard
cloths. The sensors must be
washed using clean water, with
the addition of car shampoo if
necessary. When using special
washing equipment such as high
pressure jets or steam cleaning,
clean the sensors very quickly
keeping the jet more than 10 cm
away.
WARNING
59) Only have the bumpers repainted
or any retouches to the paintwork
in the area of the sensors carried
out by an Alfa Romeo Dealership.
Incorrect paint application could
affect the operation of the parking
sensors.
