KNOWING THE INSTRUMENT PANEL

ACTIVE SAFETYSYSTEMS
The vehicle may be equipped with the
following active safety devices:
ABS (Anti-Lock Brakes);
DTC (Drive Train Control);
ESC (Electronic Stability Control);
TC (Traction Control);
PBA (Panic Brake Assist);
HSA (Hill Start Assist);
AST (Alfa™ Steering Torque);
HDC (Hill Discent Control)
For the operation of the systems, see the
following pages.
ABS (Anti-lock Braking System)
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 vehicle can be
controlled even during emergency
braking and optimising stopping
distances.
The system intervenes during braking
when 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 vehicle when braking on a
surface where the grip of the left and
right wheels varies, or on corners.The Electronic Braking Force Distribution
(EBD) system completes the system
allowing the brake force to be distributed
between the front and rear wheels.
System intervention
The ABS equipped on this vehicle is
provided with the "Brake by wire"
(Integrated Brake System - IBS) function.
With this system, the brake pedal
command given by pressing the brake
pedal is not transmitted hydraulically but
electronically, therefore, the light
pulsation that could be felt on the pedal
with the traditional system is no longer
perceptible.29) 30) 31) 32) 33) 34)
DTC (Drive Train Control)SYSTEM(where provided)
Some versions of this vehicle are
equipped with a four-wheel drive system
(AWD), activated on request, which offers
an optimal drive for countless driving
conditions and road surfaces. The system
reduces the slipping of the tyres to a
minimum, automatically redistributing
the torque to the front and rear wheels,
as needed.
To maximize fuel savings, the car with
AWD automatically passes to rear-wheel
drive (RWD) when the road and
environmental conditions are such that
they would not cause the tyres to slip.When the road and environmental
conditions require better traction, the
vehicle automatically goes to AWD mode.
35)
IMPORTANT If the system failure symbol
switches on, after starting the engine or
while driving, it means that the AWD
system is not working properly. If the
warning message activates frequently, it
is recommended to carry out the
maintenance operations.
36)
ESC (Electronic Stability Control)
SYSTEM
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 vehicle.
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
vehicle’s understeer or oversteer.
Oversteer: occurs when the car is

SAFETY

43)TC performance features must not
induce the driver to take unnecessary or
unwarranted risks. Your driving style must
always be suited to the road conditions,
visibility and traffic. The driver is, in any
case, responsible for safe driving.
44)The TC system cannot overrule the
natural laws of physics, and cannot increase
the grip available according to the condition
of the road.
45)The TC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
46)The capability of the TC must never be
tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
47)The PBA system cannot overrule the
natural laws of physics, and cannot increase
the grip available according to the condition
of the road.
48)The PBA system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
49)The capability of the PBA system must
never be tested irresponsibly and
dangerously, in such a way as to compromise
the safety of the driver, the other occupants
of the vehicle or any other road user.
50)The HSA system is not a parking brake;
therefore, never leave the vehicle without
having engaged the electric parking brake,
turned the engine off and engaged first gear,
so that it is parked in safe conditions (for
further information read the "Parking"
paragraph in the "Starting and driving"
chapter).51)There may be situations on small
gradients (less than 8%), with vehicle laden,
in which the Hill Start Assist system may not
activate, causing a slight reversing motion
and increasing the risk of collision with
another vehicle or object. The driver is, in any
case, responsible for safe driving.
52)The AST system is an aid for driving and
does not relieve the driver of responsibility
for driving the vehicle.
53)The performance of a vehicle with HDC
must never be tested in imprudent or
dangerous ways, with the possibility of
putting the safety of the driver or other
people at risk.DRIVING ASSISTANCE
SYSTEMS
The vehicle can feature the following
driving assistance systems:
BSM (Blind Spot Monitoring);
FCW (Forward Collision Warning);
TPMS (Tyre Pressure Monitoring
System).
For the operation of the systems, see the
following pages.
BSM (Blind Spot Monitoring)SYSTEM
The BSM (Blind Spot Monitoring) system
uses two radar sensors, located in the
rear bumper (one for each side - see
fig. 60 ), to detect the presence of
vehicles (cars, trucks, motorbikes, etc.) in
the rear side blind spots of your vehicle.
The system warns the driver about the
presence of vehicles in the detection
area by lighting up the warning light on
6006016V0001EM

SAFETY

"Med" and "Far" settings, in the event of a
potential accident, but permits more
dynamic driving of the car.
The system sensitivity setting is kept in
the memory when the engine is switched
off.
System limited operation warning
If the dedicated message is displayed, a
condition limiting the system operation
may have occurred. The possible reasons
of this limitation are something blocking
the camera view or a fault.
In this condition it will still be possible to
drive the car normally, but automatic
braking will not be available in the event
of an impending collision.
If an obstruction is signalled, clean the
area of the windscreen shown in fig. 63.
When the conditions limiting the system
functions end, this will go back to normal
and complete operation. Should the fault
persist, contact an Alfa Romeo
Dealership.
System failure warning
If the system switches off and a
dedicated message is shown on the
display, it means that there is a fault on
the system.
In this case, it is still possible to drive the
car, but you are advised to contact an
Alfa Romeo Dealership as soon as
possible.Radar warning not available
If conditions are such that the radar
cannot detect obstacles correctly, the
system is deactivated and a dedicated
message appears on the display. This
generally occurs in the event of poor
visibility, such as when it is snowing or
raining heavily.
The system can also be temporarily
dimmed due to obstructions such as mud,
dirt or ice on the bumper. In such cases, a
dedicated message will be shown on the
display and the system will be
deactivated. This message can
sometimes appear in conditions of high
reflectivity (e.g. tunnels with reflective
tiles or ice or snow). When the conditions
limiting the system functions end, this
will go back to normal and complete
operation.
In certain particular cases, this dedicated
message could be displayed when the
radar is not detecting any vehicles or
objects within its view range.
If atmospheric conditions are not the real
reason behind this message, check if the
sensor is dirty. It may be necessary to
clean or remove any obstructions in the
area shown in fig. 62.
If the message appears often, even in the
absence of atmospheric conditions such
as snow, rain, mud or other obstructions,contact an Alfa Romeo Dealership for a
sensor alignment check.
In the absence of visible obstructions,
cleaning the radar surface, by manually
removing the decorative cover trim,
could be required. Have this operation
performed at an Alfa Romeo Dealership.
IMPORTANT It is recommended that you
do not install devices, accessories or
aerodynamic attachments in front of the
sensor or darken it in any way, as this can
compromise the correct functioning of
the system.
Frontal collision alarm with active
braking
(where provided)
If this function is selected, the brakes are
operated to reduce the speed of the car
in the event of potential frontal impact.
This function applies an additional
braking pressure if the braking pressure
applied by the driver does not suffice to
prevent potential frontal impact.
The function is active with speed above
4.3 mph (7 km/h).
Driving in special conditions
In certain driving conditions, such as, for
example:
driving close to a bend;
the vehicle ahead is leaving a
roundabout;

SAFETY

warning will disappear automatically as
soon as the radio-frequency interference
ceases to affect the system;
aftermarket application of coloured
films on the windows that interfere with
the radio waves emitted by the TPMS;
accumulation of layers of snow or ice
on the wheels or the wheel arches;
using snow chains;
use of rim/tyre assemblies without
sensors for TPMS;
After the punctured tyre has been
repaired with the original tyre sealant
contained in the TireKit, the previous
condition must be restored, so that the
warning light is off during normal
driving.
Deactivating TPMS messages
(for markets where provided)
When replacing the standard wheels with
others that do not have TPMS sensors
(for example when substituting the
rim/tyre assembly for the winter season)
and depending on the country of sale, the
messages only can be disabled
automatically at the next start-up after
the fault.
The TPMS will emit an acoustic warning,
the
warning light will flash for about
75 seconds, then it will stay on
continuously and the instrument panel
will display the "TPMS check" messagewith dashes (– –) instead of the pressure
values on the Connect system display.
From the following ignition cycle, the
TPMS will not emit any acoustic warning
and the display will not show the
message "TPMS check", but the dashes
will be still displayed instead of the
pressure value.
The system will only resume normal
operation when all the pressure sensors
have been detected again.
IMPORTANT If wheels without pressure
sensors (e.g. wheels with winter tyres)
have been installed on the vehicle and the
standard wheels (with sensors) are
stored close the vehicle, the system
could detect the pressures of the latter
and consequently display the fault cycle
again once its has left the sensitive area.
WARNING
54)The system is an aid for vehicle driving,
it DOES NOT warn the driver about incoming
vehicles outside of the detection areas. The
driver must always maintain a sufficient
level of attention to the traffic and road
conditions and for controlling the trajectory
of the vehicle.55)The system is an aid for the driver, who
must always pay full attention while driving.
The responsibility always rests with the
driver, who must take into account the
traffic conditions in order to drive in
complete safety. The driver must always
maintain a safe distance from the vehicle in
front.
56)If the driver depresses the brake pedal
fully or carries out a fast steering during
system operation, the automatic braking
function may stop (e.g. to allow a possible
manoeuvre to avoid the obstacle).
57)The system intervenes on vehicles
travelling in the same lane. People, animals
and things (e.g. pushchairs) are not taken
into consideration.
58)If the car must be placed on a roller
bench for maintenance interventions or if it
is washed in an automatic roller washing
tunnel with an obstacle in the front part (e.g.
another car, a wall or another obstacle), the
system may detect its presence and
activate. In this case the system must be
deactivated through the settings of the
Connect system.
59)The presence of the TPMS does not
permit the driver to neglect regular checks
of the tyre pressure, including for the spare
tyre, and correct maintenance: the system is
not used to signalling a possible tyre fault.
60)Tyre pressure must be checked with
tyres rested and cold. Should it become
necessary for whatever reason to check
pressure with warm tyres, do not reduce
pressure even though it is higher than the
prescribed value. Repeat the check when the
tyres are cold.

The Active Cruise Control (ACC) is a
driver assist device which combines the
Cruise Control functions with one for
controlling the distance from the vehicle
ahead.
The device allows to hold the vehicle at
the desired speed without needing to
press the accelerator. It also allows to
hold a given distance from the vehicle
ahead (the distance can be set by the
driver).
The Active Cruise Control (ACC) uses a
radar sensor, located behind the front
bumper fig. 103 and a camera, located in
the middle area of the windscreen
fig. 104, to detect the presence of a
vehicle close ahead.

when the car speed is not within the
settable speed range;
when the ESC (or ABS or other
stability control systems) are operatingor have just operated;
when the ESC system is off;
during automatic braking by the
Forward Collision Warning Plus system
(where provided);
in the event of device failure;
when the engine is off;
in case of obstruction of the radar
sensor (in this case the bumper area
where it is located must be cleaned).
In case of system set, the conditions
described above also cause a
cancellation or deactivation of the
system with times that may vary
according to the conditions.
IMPORTANT The device is not
deactivated on reaching speeds higher
than those that can be set (160 km/h or
100 mph for instrument panel set
