AST (Alfa™ Steering Torque)SYSTEM
56)
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 settrajectory, in this situation the lateral
acceleration the car is subjected to
becomes 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
33)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.
34)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.
35)The ABS cannot overrule the natural
laws of physics, and cannot increase the grip
available according to the condition of the
road.
36)The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.
37)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.
38)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.
39)There may be a brief delay in shifting to
AWD mode after a tyre slipping event.40)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.
41)The ESC system cannot alter the natural
laws of physics, and cannot increase grip,
which depends on the condition of the road.
42)The ESC system cannot prevent
accidents, including those due to excessive
speed on corners, driving on low-grip
surfaces or aquaplaning.
43)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.
44)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.
45)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.
46)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.
47)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.

SAFETY

Frontal collision alarm with active
braking
(where provided)
Selecting the “Warning-brake” function
from the “Mode” menu on the Connect
device, allows the FCW system to apply
braking to slow the vehicle down in the
event of a potential frontal impact, in
addition to activating visual and acoustic
messages.
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;
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. 62. In cases such as these,
the system may intervene.
The vehicle ahead is leaving a
roundabout
On a roundabout, the system could
detect the presence of a vehicle ahead
which is leaving the roundabout and cut in
fig. 63.Vehicles with small dimensions and/or
not aligned in the driving lane
The system cannot detect vehicles in
front of you but outside the range of the
radar sensor and may therefore not react
in the presence of small vehicles, such as
bicycles or motorcycles fig. 64.

SAFETY

TPMS (Tyre Pressure Monitoring
System)
63) 64) 65) 66) 67) 68) 69)
31)
The car is equipped with Tyre Pressure
Monitoring System (TPMS), which can
advise the driver in the event of
insufficient tyre pressure on the basis of
the pressure when cold indicated in the
"Technical specifications" chapter.
The system comprises a radio-frequency
transmitter sensor fitted to each wheel
(on the rim inside the tyre), which is able
to send information on the inflation
pressure of each tyre to the control unit
fig. 67.
Inflation pressure varies in relation to
temperature by about 1 psi (0.07) bar
every 43.7 °F (6.5 °C). This means that
when the outdoor temperature falls, the
tyre pressure decreases. Always adjustthe tyre inflation pressure when cold.
This is defined as the tyre pressure after
at least 3 hours of vehicle inactivity or
travel of less than 1mile (1.6 km) after
the 3 hour interval.
The cold tyre inflation pressure must not
exceed the maximum pressure indicated
on the shoulder of the tyre: for further
details see the instructions in the "Rims
and tyres" paragraph, in the "Technical
data" chapter.
Tyre pressure increases when the car is
driven. This is normal, and no adjustment
of the pressure is required.
The TPMS signals the driver a possible
insufficient pressure if this falls below
the warning limit for any reason, including
the effects of low temperature and
normal loss of pressure from the tyre.
The TPMS will stop indicating insufficient
tyre pressure when it is equal to or
greater than the prescribed cold inflation
pressure. Therefore, if insufficient tyre
pressure is indicated (
warning light
on instrument panel on), increase the
inflation pressure up to the prescribed
cold inflation value.
The system automatically updates and
warning light
switches off each time
the system receives the updated
inflation pressures. The vehicle might
need to be driven at a speed higher thanabout 15.5 mph (25 km/h) up to
20 minutes for the TPMS to receive this
information.
Operating example
Supposing that the prescribed cold
inflation pressure (i.e. vehicle stationary
for at least 3 hours) is 33.4 psi (2.3 bar),
if the ambient temperature is 68°F
(20°C) and the detected tyre pressure is
28.3 psi (1.95 bar), a temperature
reduction of 19.4°F (−7°C) results in a
decrease in tyre pressure, bringing it to
approximately 24 psi (1.65 bar). This
pressure is sufficiently low to activate
the
warning light.
Heating of tyres due to driving the
vehicle may increase tyre pressure up to
approximately 28.3 psi (1.95 bar), 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

SAFETY

WHEELS AND TYRES
171) 172) 173)
Before embarking on a long trip, and
every two weeks, check the tyre inflation
pressure. Check the tyres when cold.
SNOW CHAINS
81)
Rear Wheel Drive and All-wheel drive
versions
0.28 inch (7 mm) snow chains can be used
on all tyres. For tyres up to 8.86 in
(225 mm) in width (205/60R16,
225/55R16, 225/50R17, 225/45R18),
it is also possible to install 0.35 in (9 mm)
chains.
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 car
driveability, with the risk of losing control
of the car 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 (6200 /
9300 miles (10000 / 15000 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 tractionperformance on wet, muddy or snowy
roads, guaranteeing optimal driveability
of the vehicle.
In the case of irregular wear of the tyres
identify the cause and correct it as soon
as possible, by contacting an Alfa Romeo
Dealership.
All Wheel Drive (AWD) versions
It is recommended to avoid situations
with a large difference in wear between
the front and rear tyres and to strictly
use winter tyres of the sizes given in the
“Rims and tyres provided” table.
The AWD systems and the original tyres
were developed together to ensure the
vehicle’s best performance. When
changing the tyres, it is therefore
recommended to use the same “AR”
marked tyres, to maintain the same level
of performance and component life.
WARNING
171)The road holding qualities of the car
also depend on the correct inflation pressure
of the tyres.
172)If tyre pressure is too low, it may
overheat and be severely damaged as a
result.
173)Never submit alloy rims to repainting
treatments requiring the use of
temperatures exceeding 150°C. The
mechanical properties of the wheels could
be impaired.

WARNING
178)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
85)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.
