light Alfa Romeo Giulia 2016 Service Manual

following items in sequence: "Settings",
"Safety", "Forward Collision Warning" and
"Status".
The system can be deactivated even with
the ignition device ON.
IMPORTANT The system status can be
changed with vehicle at a standstill only.
Activation/deactivation
The Forward Collision Warning system is
activated whenever the engine is started
regardless of that shown on the Connect
system.
Following a deactivation, the system will
not warn the driver about the possible
collision with the preceding vehicle,
regardless of the setting selected with
the Connect system.
IMPORTANT Each time the engine is
started, the system is activated
regardless of where was when it was
previously switched off.
This function is not active at a speed
lower than 4 mph (7 km/h) or higher than
125 mph (200 km/h).
The system is active when:
each time the engine is started;
is active (ON) on the Connect system;
the ignition device is at ON;
the vehicle speed is between 4 (7) and
125 mph (200 km/h);
the front seat belts are fastened;
the "Alfa DNA™ Pro" selector is not in
RACE position (where present).
Changing the system sensitivity
The sensitivity of the system can be
changed through the Connect system
menu, choosing from one of the following
three options: "Near", "Med" or "Far". See
the description in the Connect system
supplement for how to change the
settings.
The pre-set option is "Med". With this
setting, the system warns the driver of a
possible collision with the vehicle in front
when that vehicle is at a standard
distance, between that of the other two
settings.
With the system sensitivity set to "Far",
the system will warn the driver of a
possible collision with the vehicle in front
when that vehicle is at a greater distance,
thus providing the possibility of acting on
the brakes more lightly and gradually.
This setting provides the drivers with the
maximum possible reaction time to
prevent a potential accident.
With the option set to "Near", the system
will warn the driver of a possible collision
with the vehicle in front when that vehicle
is close. This setting offers the driver a
lower reaction time compared to the
"Med" and "Far" settings, in the event of a
potential collision, but permits more
dynamic driving of the vehicle.The system sensitivity setting is kept in
the memory when the engine is switched
off.
System limited operation signal
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 indicated in
fig. 69.
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 signalling
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
vehicle, but you are advised to contact an
Alfa Romeo Dealership as soon as
possible.

SAFETY

the system and must not be regarded as
faults.
The system has been designed for
road use only. If the vehicle is driven on a
track, the system must be deactivated to
avoid unnecessary warnings. Automatic
deactivation is signalled by the dedicated
warning light/symbol switching on in the
instrument panel (see the instructions in
the "Warning lights and messages"
paragraph, "Knowing the instrument
panel" chapter).
TPMS (Tyre Pressure Monitoring
System)
60) 61) 62) 63) 64) 65) 66)
28)
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. 75.The inflation pressure varies, depending
on the temperature, of about 0.07 bar
(1 psi) every 43.7°F (6.5°C). This means
that a decrease of the external
temperature corresponds to a decrease
of the tyre pressure. Always adjust the
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 1 mi (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 vehicle
is driven. This is normal, and no
adjustment of the pressure is required.
The TPMS signals the driver a possibleinsufficient 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 than
about 15 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 2.3 bar (33.4 psi) ,
if the ambient temperature is 68°F
(20°C) and the detected tyre pressure is
1.95 bar (28.3 psi), a temperature
reduction of 19.4°F (−7°C) results in a
decrease in tyre pressure, bringing it to
approximately 1.65 bar (23.9 psi). This
pressure is sufficiently low to activate
the
warning light.
Heating of tyres due to driving the
7506016S0009EM
75

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.

SBA (Seat Belt Alert)SYSTEM
The SBA system warns the passengers of
the front and rear (where provided) seats
if their seat belt is not fastened.
The system signals unfastened seat belts
with visual warnings (warning lights on in
the instrument panel and icons on the
display) and an acoustic signal (see the
following paragraphs).
NOTE Contact an Alfa Romeo Dealership
to deactivate the acoustic warning. The
acoustic warning can be reactivated at
any time through the Connect system.
FRONT SEAT BELT WARNING LIGHT
BEHAVIOUR
When the ignition key is turned to ON, the
warning light
(see fig. 79 ) lights up for
a few seconds, regardless of the status
of the front seat belts.
With vehicle at a standstill, if the driver
side seat belt or the passenger side seat
belt (with occupant seated) is
unfastened, the warning light stays on
constantly.As soon as the threshold of 5 mph
(8 km/h) is exceeded for a few seconds
(variable according to the vehicle
conditions) with driver or passenger side
(with passenger seated) seat belts
unfastened, an acoustic warning is
activated together with the flashing of
the
warning light for approximately
105 seconds.
When this cycle of warnings is activated
it will stay on for its entire length
(regardless of the vehicle speed) or until
the seat belts are fastened again.
When the reverse is engaged, during the
cycle of warnings, the acoustic signal is
deactivated and the
warning light
turns on constantly. The cycle of
warnings will be reactivated as soon as
speed exceeds 5 mph (8 km/h) again.
REAR SEAT BELT ICON BEHAVIOUR
(where provided)
The icons are shown on the display
(fig. 80 ) after a few seconds have
elapsed since the ignition device is
turned to ON and disappear after
approximately 30 seconds.
After a door closes, or following a change
in belt fastening status, the icons are
shown again for approximately
30 seconds before disappearing.
The icons shown on the display indicate:
1 - rear leftseat belt;
2 - rear centralseat belt, (where
provided);
3 - rear rightseat belt.
The icons are displayed according to the
corresponding seat belts in the rear
seats, and stay on for about 30 seconds
from the last seat belt status change:
7906066S0001EM
8006066S0002EM
80
SAFETY

if the seat belt is fastenedthe
corresponding icon will be green;
if the seat belt is unfastenedthe
corresponding icon will be red.
If a rear seat belt is unfastened, an
acoustic warning (3 "beeps") will be
activated along with the relevant icon
lighting up in the display.
Furthermore the icons will light up again
for 30 seconds each time one of the rear
doors is closed.
The visual indication (flashing red) will
start and stop independently for each
warning light if several seat belts are
unfastened.
The icon will turn green after the
corresponding seat belt has been
fastened.
The rear seat icons will go out, regardless
of the state of the belt (red icon or green
icon), approximately 30 seconds after
the last signal.
IMPORTANT NOTES
As far as the rear seats are concerned,
the SBR system will only indicate
whether the seat belts are unfastened
(red icon) or fastened (green icon), not
the presence of any passengers.
The warning lights/icons all stay off if all
seat belts (front and rear) are fastened
when the ignition device is set to ON.
For the rear seats, the icons will activatea few seconds after the ignition device
has been turned to ON, regardless of the
status of the seat belts (even if the seat
belts are all fastened).
All the warning lights/icons will come on
when at least one belt changes from
fastened to unfastened status or vice
versa.
PRETENSIONERS
The vehicle is equipped with front and
rear lateral seat belt pretensioners,
which draw back the seat belts by several
centimetres in the event of a strong
frontal impact. This guarantees the
perfect adherence of the seat belts to
the occupant's bodies before the
retention action begins.
It is evident that the pretensioners have
been activated when the belt withdraws
toward the retractor.
This car is also equipped with a second
pretensioner on the front seat belts
(fitted in the kick plate area). Its
activation is signalled by the shortening
of the metal cable.
A slight discharge of smoke may be
produced during the activation of the
pretensioner which is not harmful and
does not involve any fire hazard.
The pretensioner does not require any
maintenance or lubrication: any changes
to its original conditions will invalidate its
efficiency.
If, due to unusual natural events (floods,
sea storms, etc.), the device has been
affected by water and/or mud, contact an
Alfa Romeo Dealership to have it
replaced.

Main recommendations to carry
children safely
Install the child restraint systems on
the rear seat, which is the most protected
position in the event of an impact.
Keep children in rearward facing child
restraint systems for as long as possible,
until 3–4 years old if possible.
If a rear facing child restraint system is
installed on the front seat, passenger's
side, it is recommended to remove the
head restraint (refer to the procedure
described in "Head restraint" paragraph,
"Knowing your vehicle" chapter). The head
restraint must be repositioned properly if
no child restraint system is to be
transported.
If the passenger's front airbag is
deactivated always check the warning
light on the front dashboard to make sure
that it has actually been deactivated.
Carefully follow the instructions
supplied with the child restraint system.
Keep the instructions in the vehicle along
with the other documents and this
handbook. Do not use second-hand child
restraint systems without instructions.
Only one child is to be strapped into
each restraint system; never carry two
children using one child restraint system.
Always check that the seat belts do
not rest on the child’s neck.
Always check that the seat belt is well
fastened by pulling on it.
While travelling, do not let the child sit
incorrectly or unfasten the belts.
Never allow a child to put the belt's
diagonal section under an arm or behind
their back.
Never carry children on your lap, even
newborns. No one can hold a child in the
case of an accident.
In the event of an accident, replace the
child restraint system with a new one.
WARNING
73)SEVERE DANGER When a front
passenger airbag is fitted, do not install
rearward facing child restraint systems on
the front passenger seat. Deployment of the
airbag in an accident could cause fatal
injuries to the child regardless of the
severity of the collision. It is advisable to
always carry children in a child restraint
system on the rear seat, which is the most
protected position in the event of a collision.
74)On the sun visor there is a label with
suitable symbols reminding the user that it is
compulsory to deactivate the airbag if a
rearward facing child restraint system is
fitted. Always comply with the instructions
on the passenger side sun visor (see the
"Supplementary Restraint System (SRS) -
Airbag" paragraph).75)Should it be necessary to carry a child on
the passenger side front seat in a rear facing
child restraint system, the passenger side
front airbag and side bag must be
deactivated through the Connect system
main menu (see the Supplementary
Restraint System (SRS) - Airbag"
paragraph), verifying deactivation by
checking whether the
OFFLED has
illuminated on the front ceiling light. Move
the passenger's seat as far back as possible
to avoid contact between the child seat and
the dashboard.
76)Do not move the front or rear seat if a
child is seated on it or on the dedicated child
restraint system
77)Incorrect fitting of the child restraint
system may result in an inefficient
protection system. In the event of an
accident the child restraint system may
become loose and the child may be injured,
even fatally. When fitting a restraint system
for newborns or children, strictly comply
with the instructions provided by the
Manufacturer.
78)When the child restraint system is not
used, secure it with the seat belt or with the
ISOFIX anchorages, or remove it from the
vehicle. Do not leave it unsecured inside the
passenger compartment. In this way, in the
case of sudden braking or an accident, it will
not cause injuries to the occupants.
79)After installing a child restraint system,
do not move the seat: always remove the
child restraint system before making any
adjustment.

Passenger side front airbag
This consists of an instantly inflating bag
contained in a special recess in the
dashboard fig. 94; this bag has a larger
volume than that of the driver's.
Passenger side front airbag and child
restraint systems
Rearward facing child restraint systems
mustNEVERbe fitted on the front seat

ALWAYScomply with the instructions on
the label stuck on the passenger side sun
visor fig. 95, and shown in table fig. 98.
Deactivating/activating the passenger
airbags: front airbag and side bag
(where provided)
For deactivating the passenger front and
side airbags, on the Connect system,
select the following functions in
sequence from the main menu, which can
be opened by pressing the MENU button:
"Settings", "Safety", "Passenger airbag"
which can be selected by turning and
pressing the Rotary Pad fig. 96. The
system will detect the activation/
deactivation state of the airbags and
confirm change of state. Press the Rotary
Pad to continue.The OFF and ON state LEDs are provided
on the front ceiling light. Moving the
ignition device to AVV, the two LEDs
switch on for a few seconds. If not,
contact a Alfa Romeo Dealership. During
the first seconds, the activation of the
LEDs does not actually show the
passenger protection status, but only
checks its correct operation.
After a test of a few seconds, the LEDs
will indicate the status of the passenger
airbag protection.

89)Do not affix rigid objects to the garment
hooks or support handles.
90)Do not rest your head, arms or elbows on
the door, windows or the area in which the
Window bag is located to avoid possible
injury during airbag inflation.
91)Never lean your head, arms or elbows
out of the window.
92)If, when the ignition device is turned to
ON, the
warning light does not switch on
or stays on whilst driving, a fault may have
occurred in the restraint systems. In this
case the airbags or pretensioners may not
be deployed in an impact or, in a lower
number of cases, they may be deployed
accidentally. Before continuing, contact an
Alfa Romeo Dealership immediately to have
the system checked.
93)In case of a LED
OFFfailure (located
on the front courtesy light), thewarning
light appears on the instrument panel.
94)On cars with side bags, do not cover the
front seat backrests with extra covers.
95)Do not travel carrying objects in your
lap, in front of your chest or between your
lips (pipe, pencils, etc.): they could cause
severe injury if the airbag is deployed.
96)If the car has been subject to theft,
attempted theft, vandalism, or flooding,
have the airbag system inspected at an Alfa
Romeo Dealership.
97)Malfunction of the airbag failure
warning light is indicated by the activation
of an airbag failure icon and a dedicated
message on the instrument panel display.
The pyrotechnic charges are not disabled.
Before continuing, contact an Alfa Romeo
Dealership immediately to have the system
checked.98)The airbag deployment threshold is
higher than that of the pretensioners. For
collisions in the range between the two
thresholds, it is normal for only the
pretensioners to be activated.
99)The airbag does not replace seat belts
but increases their efficiency. Because front
airbags are not deployed for low-speed
crashes, side collisions, rear-end shunts or
rollovers, occupants are protected, in
addition to any side bags, only by their seat
belts, which must therefore always be
fastened.
