AST (Alfa™ Steering Torque)SYSTEM
53)
The AST function uses the integration of
the ESC system with the electric power
steering to increase the safety level of
the whole vehicle.
In critical situations (braking on surfaces
with different grip conditions), through
the AST function the ESC system
controls the steering to implement an
additional torque contribution on the
steering wheel, to suggest the most
correct manoeuvre to the driver.
The coordinated action of the brakes and
steering increases the sensation of
safety and control of the vehicle.
ATV (Alfa™ Active Torque Vectoring)
SYSTEM
The dynamic drive control is used to optimize
and balance the drive torque between the
wheels of the same axis. The ATV system
improves the grip in turns, sending more drive
torque to the external wheel.
Given that, in a turn, the external wheels
of the car travel more than the internal
ones and therefore turn faster, sending a
higher thrust to the external rear wheel
allows for the car to be more stable and
to not suffer a phenomenon called
"understeer". Understeer occurs when,
during a turn, a car tends to widen the set
trajectory, in this situation the lateral
acceleration the car is subjected tobecomes higher that the grip of the tyres,
which are unable to maintain the car in
the trajectory set by the driver through
the steering angle determined by turning
the steering wheel.
WARNING
30)For maximum efficiency of the braking
system, a bedding-in period of about 500 km
(310 miles) is required: during this period it
is advisable to avoid sharp, repeated and
prolonged braking.
31)If the ABS intervenes, this indicates that
the grip of the tyres on the road is nearing its
limit: you must slow down to a speed
compatible with the available grip.
32)
The ABS cannot overrule the natural laws
of physics, and cannot increase the grip
available according to the condition of the road.
33)The ABS cannot prevent accidents, including
those due to excessive speed on corners, driving
on low-grip surfaces or aquaplaning.
34)The capability of the ABS must never be
tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
35)
For the correct operation of the ABS, the
tyres must of necessity be the same make and
type on all wheels, in perfect condition and, above
all, of the prescribed type and dimensions.
36)There may be a brief delay in shifting to
AWD mode after a tyre slipping event.
37)When a DTC system failure symbol
appears, the driver must be aware of the
different driving reaction and therefore
reduce the speed. The symbol
warns the
driver not to drive in areas that require
four-wheel drive or on snow-covered roads.38)The ESC system cannot alter the natural
laws of physics, and cannot increase grip,
which depends on the condition of the road.
39)The ESC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
40)The capability of the ESC system must
never be tested irresponsibly and
dangerously, in such a way as to compromise
personal safety and the safety of others.
41)For the correct operation of the ESC
system, the tyres must necessarily be of the
same make and type on all wheels, in perfect
condition and, above all, of the prescribed
type and size.
42)ESC 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.
43)For the correct operation of the TC
system, the tyres must of necessity be the
same make and type on all wheels, in perfect
condition and, above all, of the prescribed
type and dimensions.
44)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.
45)The TC system cannot overrule the
natural laws of physics, and cannot increase
the grip available according to the condition
of the road.
46)The TC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.

SAFETY

Radar indication 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 could be necessary to
clean or remove any obstructions in the
area shown in fig. 68.
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
vehicle 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 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;
vehicles with small dimensions and/or
not aligned in the driving lane;
lane change by other vehicles;
vehicles travelling at right angles to
the vehicle.
system intervention might be
unexpected or delayed. The driver must
therefore be very careful, keeping
control of the vehicle to drive in complete
safety.
IMPORTANT In particularly complex
traffic conditions, the driver can
deactivate the system manually through
the Connect system.
Driving close to a bend
When entering or leaving a wide bend, the
system may detect a vehicle that is in
front of you, but that is not driving in the
same lane fig. 70. In cases such as these,
the system may intervene.
7006016S0005EM
73

The vehicle ahead is leaving a
roundabout.
On a roundabout, the system could
intervene if it detects a vehicle ahead
that is leaving the roundabout fig. 71.
Vehicles with small dimensions and/or
not aligned in the driving lane
The system cannot detect vehicles in
front of you that are outside the range of
the radar sensor. Therefore it may not
react to small vehicles, such as bicycles
or motorcycles fig. 72.Lane change by other vehicles
Vehicles suddenly changing lane, entering
the same lane as your car and within the
radar sensor’s operating range, may
cause the system to intervene fig. 73.
Vehicles travelling at right angles to
the vehicle
The system could temporarily react to a
vehicle that is passing through the radar
sensor’s operating range at right angles
fig. 74.Important notes
The system has not been designed to
prevent impacts and cannot detect
possible conditions leading to an
accident in advance. Failure to take into
account this warning may lead to serious
or fatal injuries.
The system may activate, assessing
the trajectory of the vehicle, for the
presence of reflecting metal objects
different from other vehicles, such as
safety barriers, road signs, barriers
before parking lots, tollgates, level
crossings, gates, railways, objects near
road constructions sites or higher than
the vehicle (e.g. a flyover). In the same
way, the system may intervene inside
multi-storey car parks or tunnels, or due
to a glare on the road surface. These
possible activations are a consequence
of the real driving scenario coverage by

SAFETY

vehicle may increase tyre pressure up to
approximately 1.95 bar (28.3 psi), but
the
warning light will stay on. In this
situation, the warning light will switch off
only after the tyres are inflated to the
prescribed cold pressure value for the
car.
IMPORTANT The TPMS is designed for
original tyres and wheels. The prescribed
pressures and consequent alarm
thresholds set in the TPMS are based on
the dimensions of the tyres fitted on the
vehicle. Using spare wheels of a size, type
and/or design different from the original
ones may cause an irregular operation of
the system and damage the sensors.
Aftermarket fitted wheels may damage
the sensors. Using aftermarket tyre
sealants may damage the Tyre Pressure
Monitoring System (TPMS) sensor. If
aftermarket tyre sealant is used it is
recommended to go to an Alfa Romeo
Dealership to have the sensors checked.
After checking or adjusting the tyre
pressure, always refit the valve cap to
prevent humidity and dirt from entering,
these may damage the Tyre Pressure
Monitoring System sensor.
INSUFFICIENT TYRE PRESSURE
INDICATION
If an insufficient pressure value is
detected on one or more tyres, the
warning light on the instrument panelswitches on and the dedicated messages
are shown on the display. The system also
highlights the tyre or tyres with
insufficient pressure graphically. An
acoustic signal is also emitted.
In this case, stop the car, check the
inflation pressure of each tyre and inflate
them to the correct cold inflation
pressure value, shown on the display or in
the dedicated TPMS menu.
TPMS TEMPORARILY DISABLED
TPMS check message
If a system failure is present, the
warning light flashes for about
75 seconds and then stays on solid. An
acoustic signal is also emitted.
A dedicated message and dashes "– –"
instead of the pressure value are shown
on the display, to indicate that detection
is impossible.
When the ignition device is set to STOP
and then back to ON, the indication
sequence repeats provided that the
failure is still resent.
The
warning light switches off when
the failure condition disappears and the
pressure value is displayed again in place
of the dashes.
A fault in the system could occur in the
following cases:
strong radio-frequency noises could
hinder the regular operation of the TPMS.This condition will be indicated by a
dedicated message on the display. The
message 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.
TPMS deactivation
The TPMS can be deactivated by
replacing the wheels equipped with
TPMS with others that are not (e.g. upon
replacement of the wheel assemblies in
winter) and if compatible with the
country of purchase that makes this
possibility available. Then drive for at
least 20 minutes at a speed higher than
about 15 mph (25 km/h).
The TPMS will emit an acoustic warning,
the
warning light will flash for about
75 seconds, then will stay on constantly
and the instrument panel will display the

SAFETY

LIFTING THE VEHICLE
If the car needs to be jacked up, go to an
Alfa Romeo Dealership which is equipped
with shop jacks or jack arms.
The vehicle lifting points are marked on
the side skirts with the
symbols (see
illustration in fig. 153 ).

70)
Rear Wheel Drive and All-wheel drive
versions
0.28 in (7-mm) snow chains can be used
on all tyres. For tyres up to 8.8
Ûin
(225 mm) in width (205/60R16,
225/55R16, 225/50R17, 225/45R18),
it is also possible to install 0.35 in (9 mm)
chains.
We recommend using snow chains
available from the Alfa Romeo
Dealership.
Important notes
The use of snow chains should be in
compliance with local regulations of each
country. In certain countries, tyres
marked with code M+S (Mud and Snow)
are considered as winter equipment;
therefore their use is equivalent to that
of the snow chains.
The snow chains may be applied only to
the rear wheel tyres.
Check the tension of the snow chains
after the first few metres have been
driven.
IMPORTANT Using snow chains with
tyres with non-original dimensions may
damage the vehicle.
IMPORTANT Using different size or type
(M+S, snow, etc.) tyres between front and
rear axle may adversely affect vehicle
driveability, with the risk of losing control
of the vehicle and resulting accidents.
SUGGESTIONS ABOUT THE ROTATION
OF THE TYRES
The front and rear tyres are subject to
different loads and stress due to
steering, manoeuvres and braking. For
this reason they are subject to uneven
wear.
To resolve this problem, tyres should be
rotated at the appropriate time
(3,000/6,000 mi - 5,000/10,000 km).
Inverting the tyres means moving them
to different positions on the same side of
the car (front to back and vice versa).
IMPORTANT Crossing the tyres is not
advised, so placing a tyre on a different
axle on the other side of the car is
impossible.
IMPORTANT On cars equipped with
differentiated tyres (tyre size different
between front and rear axles, ex. QV
version) rotation of any of the tyres is not
advised.
Tyre rotation contributes to the
preservation of the grip and traction

WARNING
160)If winter tyres with a lower speed rating than that indicated in the Registration Document are used, do not exceed the maximum speed
corresponding to the speed rating of the tyres used.
IMPORTANT
73)Keep your speed down when snow chains are fitted; do not exceed 50 km/h. Avoid potholes, do not drive over steps or sidewalks and do not
drive long distances over roads without snow, to avoid damaging both your vehicle and the road surface.
