2016 Alfa Romeo Giulia wheel size

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

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
76
SAFETY

"TPMS check" message with some
dashes (– –) instead of the pressure
values.
From the following ignition cycle, the
TPMS will not emit any acoustic signal
and the display will not show the
message "TPMS check", but the dashes
will be still displayed instead of the
pressure value.
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 Forward Collision Warning (FCW)
system is automatically deactivated when
RACE mode is selected.
56)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.
57)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).58)The system intervenes on vehicles
travelling in the same lane. People, animals
and things (e.g. pushchairs) are not taken
into consideration.
59)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.
60)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.
61)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.
62)Should one or more wheels be fitted
without sensors, the system will no longer be
available and a warning message will be
shown on the display, until wheels with
sensors are fitted again.
63)The TPMS cannot indicate sudden tyre
pressure drops (e.g. if a tyre bursts). In this
case, stop the vehicle, braking with caution
and avoiding abrupt steering.
64)Changes in outside temperature may
cause tyre pressures to vary. The system
may temporarily indicate insufficient
pressure. In this case, check the tyre
pressure when cold and, if necessary,
restore the inflation values.65)Replacing standard tyres with winter
tyres and vice versa requires TPMS system
adjustment that must only be performed by
Alfa Romeo Dealerships.
66)When a tyre is removed, it is advisable
to replace the rubber valve seal as well:
contact an Alfa Romeo Dealership. The
fitting/removal of the tyres and/or rims
require special care. To avoid damaging or
fitting the sensors incorrectly, tyre and/or
rim fitting/removal operations should only
be carried out by specialised staff. Contact
an Alfa Romeo Dealership.IMPORTANT
19)The system may have limited or absent
operation due to weather conditions such as:
heavy rain, hail, thick fog, heavy snow.
20)The section of the bumper before the
sensor must not be covered with adhesives,
auxiliary headlights or any other object.
21)System intervention might be
unexpected or delayed when other vehicles
transport loads projecting from the side,
above or from the rear, with respect to the
normal size of the vehicle.
22)Operation can be adversely affected by
any structural change made to the vehicle,
such as a modification to the front geometry,
tyre change, or a heavier load than the
standard load of the vehicle.
23)Incorrect repairs made on the front part
of the vehicle (e.g. bumper, chassis) may alter
the position of the radar sensor, and
adversely affect its operation. Go to an Alfa
Romeo Dealership for any operation of this
type.

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 ).
WHEELS AND TYRES
157) 158) 159)
SNOW CHAINS
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
15309056S0001EM
153

performance 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
157)The road holding qualities of the car
also depend on the correct inflation pressure
of the tyres.
158)If tyre pressure is too low, it may
overheat and be severely damaged as a
result.
159)Never submit alloy rims to repainting
treatments requiring the use of
temperatures exceeding 150°C. The
mechanical properties of the wheels could
be impaired.
IMPORTANT
70)Keep your speed down when snow chains
are fitted; do not exceed 50 km/h (or the
equivalent in miles). 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.
BODY
PRESERVING THE BODYWORK
Paint
71)7)
Touch up abrasions and scratches
immediately to prevent the formation of
rust.
Some parts of the vehicle may be
covered with a matt paint which, in order
to be maintained intact, requires special
care: see the instructions in the warning
at the end of this paragraph
72)
To correctly wash the vehicle, follow
these instructions:
if high pressure jets or cleaners are
used to wash the vehicle, keep a distance
of at least 40 cm from the bodywork to
avoid damage or alteration. Build up of
water could cause damage to the vehicle
in the long term;
to make it easier to remove any dirt
deposits in the area where the blades are
normally located it is recommended to
position the windscreen wipers vertically
(service position), for more information
consult the “Maintenance procedures”
paragraph in this chapter.

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.
