sensor Alfa Romeo Giulia 2017 User Guide

and environmental conditions are such
that they wouldn't cause the tires to
slip. When the road and environmental
conditions require better traction, the
vehicle automatically goes to AWD
mode.
The driving mode, RWD or AWD, is
shown on the instrument cluster
display.
Note: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.
Electronic Stability
Control (ESC) 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 path that
the driver intends to follow and
compares it with the car’s effective
path. When the real path deviates from
the desired path, the ESC system
intervenes to counter the vehicle’s
understeer or oversteer.
Oversteer occurs when the car is
turning more than it should according
to the angle of the steering wheel.
Understeer occurs when the vehicle
is turning less than it should according
to the angle of the steering wheel.
System Intervention
The intervention of the system is
indicated by the flashing of the ESC
warning light on the instrument panel,
to inform the driver that the vehicle
stability and grip are critical.
Warning!
Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase
the traction afforded by prevailing road
conditions. ESC cannot prevent accidents,
including those resulting from excessive
speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot
prevent accidents resulting from loss of
vehicle control due to inappropriate driver
input for the conditions. Only a safe,
attentive, and skillful driver can prevent
accidents. The capabilities of an ESC
equipped vehicle must never be exploited
in a reckless or dangerous manner which
could jeopardize the user’s safety or the
safety of others.
Vehicle modifications, or failure to
properly maintain your vehicle, may change
the handling characteristics of your vehicle,
and may negatively affect the performance
of the ESC system. Changes to the
steering system, suspension, braking
system, tire type and size or wheel size
may adversely affect ESC performance.
Improperly inflated and unevenly worn tires
may also degrade ESC performance. Any
vehicle modification or poor vehicle
maintenance that reduces the effectiveness
of the ESC system can increase the risk of
loss of vehicle control, vehicle rollover,
personal injury and death.
Traction Control System
(TCS)
The system automatically operates in
the event of slipping, loss of grip on wet
roads (hydroplaning), and acceleration
on one or both drive wheels on roads
that are slippery, snowy, icy, etc.
Depending on the slipping conditions,
two different control systems are
activated:
If the slipping involves both drive
wheels, the system intervenes, reducing
the power transmitted by the engine.
If the slipping only involves one of the
drive wheels, the Brake Limited
Differential (BLD) function is activated,
automatically braking the wheel which
is slipping (the behavior of a self-locking
differential is simulated). This will
increase the engine torque transferred
to the wheel which isn't slipping.
97

Dynamic Steering
Torque (DST) System
The DST 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), the ESC
system controls the steering through
the DST function to implement an
additional torque contribution on the
steering wheel in order to suggest the
most correct maneuver to the driver.
The coordinated action of the brakes
and steering increases the sensation of
safety and control of the vehicle.
Note:
The DST feature is only meant to help
the driver realize the correct course of
action through small torques on the
steering wheel, which means the
effectiveness of the DST feature is
highly dependent on the drivers
sensitivity and overall reaction to the
applied torque. It is very important to
realize that this feature will not steer the
vehicle, meaning the driver is still
responsible for steering the vehicle.
Active Torque Vectoring
(ATV) System
The dynamic drive control is used to
optimize and balance the drive torque
between the wheels of the same axles.
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 an "understeer"
condition. Understeer occurs when the
vehicle is turning less than appropriate
for the steering wheel position.
AUXILIARY DRIVING
SYSTEMS
The vehicle can feature the following
auxiliary driving systems:
Blind Spot Monitoring (BSM)
Forward Collision Warning (FCW)
Tire Pressure Monitoring System
(TPMS)
For the operation of the systems, see
the following pages.
Blind Spot Monitoring
(BSM) System
The Blind Spot Monitoring (BSM)
system uses two radar sensors, located
in the rear bumper (one for each side),
to detect the presence of vehicles
(vehicles, trucks, motorcycles, etc.) in
the rear side blind spots of your vehicle.
GUID-06016S0001EMRear Sensor Location
99

The system warns the driver about the
presence of vehicles in the detection
area by lighting up, on the relevant side,
the warning light located on the door
mirror.
When the engine is started the warning
light turns on to signal the driver that
the system is active.
Sensors
The sensors are activated when any
forward gear is engaged at a speed
higher than approximately 6 mph
(10 km/h) or when reverse is engaged.
The sensors are temporarily deactivated
when the vehicle is stationary and the
PARK (P) mode active.
The detection area of the system
covers approximately a lane on both
sides of the vehicle which is around 9 ft
(3 m).This area begins from the door mirror
and extends for approximately 19 ft
(6 m) towards the rear part of the
vehicle.
When the sensors are active, the
system monitors the detection areas on
both sides of the vehicle and warns the
driver about the possible presence of
vehicles in these areas.
While driving, the system monitors the
detection area from three different input
points (side, rear and front) to check
whether a alert needs to be sent to the
driver. The system can detect the
presence of a vehicle in one of these
three areas.
Note:
The system does not alert the driver
for the presence of fixed object (e.g.
safety barriers, poles, walls, etc.).
However, in some circumstances, the
system may activate in the presence of
these objects. This is normal and does
not indicate a system malfunction.
The system does not alert the driver
about the presence of vehicles coming
from the opposite direction, in the
adjacent lanes.
Warning!
The Blind Spot Monitoring system is only
an aid to help detect objects in the blind
spot zones. The BSM system is not
designed to detect pedestrians, bicyclists,
or animals. Even if your vehicle is equipped
with the BSM system, always check your
vehicle’s mirrors, glance over your
shoulder, and use your turn signal before
changing lanes. Failure to do so can result
in serious injury or death.
Important Notes
If a trailer is hitched to the vehicle, the
system automatically deactivates.
For the system to operate correctly, the
rear bumper area where the radar
sensors are located must stay free from
snow, ice and dirt gathered from the
road surface.
Do not cover the rear bumper area
where the radar sensors are located
with any object (e.g. adhesives, bike
rack, etc.).
If you wish to install the tow hook after
purchasing the vehicle, you need to
deactivate the system via the Connect
system. To access the function, select
the following items in sequence on the
main menu: "Settings", "Safety", and
"Blind Spot Alert".
06016S0002EMBSM Indicator Light
100
SAFETY

Rear View
The system detects vehicles coming
from the rear part of your vehicle on
both sides and entering the rear
detection area with a difference in
speed of less than 31 mph (50 km/h)
with relation to your vehicle.
Overtaking Vehicles
If another vehicle is overtaken slowly,
with a difference in speed of less than
approximately 15 mph (25 km/h) and
the vehicle stays in the blind spot for
approximately 1.5 seconds, the
warning light on the door mirror of the
corresponding side lights up.
If the difference in speed between the
two vehicles is greater than
approximately 15 mph (25 km/h), the
warning light does not light up.
Rear Cross Path Detection (RCP)
System
This system helps the driver during
reverse maneuvers in the case of
reduced visibility.
The RCP system monitors the rear
detection areas on both sides of the
vehicle to detect objects moving
towards the sides of the vehicle, with a
minimum speed between approximately
1 mph (1 km/h) and 2 mph (3 km/h)
and objects moving at a maximum
speed of 21 mph (35 km/h), in areas
such as parking lots.
The system activation is signaled to the
driver by a visual and acoustic warning.Note:
If the sensors are covered by
objects or vehicles, the system will not
warn the driver.
Warning!
Rear Cross Path Detection (RCP) is not a
back up aid system. It is intended to be
used to help a driver detect an oncoming
vehicle in a parking lot situation. Drivers
must be careful when backing up, even
when using RCP. Always check carefully
behind your vehicle, look behind you, and
be sure to check for pedestrians, animals,
other vehicles, obstructions, and blind
spots before backing up. Failure to do so
can result in serious injury or death.
Operating Mode
The system may be activated/
deactivated via the Connect system. To
access the function, select the following
items on the main menu in sequence:
"Settings", "Safety" and "Blind Spot
Alert".
"Blind Spot Alert", "Visual" Mode
When the system is enabled, a visual
warning is sent to the door mirror on
the side of the detected object.
The visual warning on the mirror will
blink if the driver switches on the
direction indicators, thus indicating the
intention to change lane.
The warning will be fixed if the driver
stays in the same lane. "Blind Spot Alert" Function
Deactivation
When the system is deactivated ("Blind
Spot Alert" mode off), the BSM or RCP
systems will not emit either acoustic or
visual warnings.
The BSM system will store the
operating mode running when the
engine was stopped. Each time the
engine is started, the operating mode
stored previously will be recalled and
used.
General Information
This vehicle has systems that operate
on radio frequency that comply with
Part 15 of the Federal Communications
Commission (FCC) rules and with
Industry Canada Standards RSS-
GEN/210/220/310.
Operation is subject to the following
two conditions:
1. The device may not cause harmful
interference.
2. The device must accept any
interference received, including
interference that may cause undesired
operation of the device.
Changes or modifications to any of
these systems by other than an
authorized service facility could void
authorization to use this equipment.
101

In this case, it is still possible to drive
the vehicle, but you are advised to
contact an authorized dealer as soon
as possible.
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.
If the message appears often, even in
the absence of atmospheric conditions
such as snow, rain, mud or otherobstructions, contact an authorized
dealer for a sensor alignment check.
In the absence of visible obstructions,
manually removing the decorative cover
trim and cleaning the radar surface
could be required. Have this operation
performed at an authorized dealer.
Note:
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 — If Equipped
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.
Note: 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 in front
you, but not driving on the same driving
lane. In cases such as these, the
system may intervene.
06016S0005EMDriving Around Wide Curves
104
SAFETY

The Vehicle Ahead Is Leaving A
Roundabout
On a roundabout, the system could
intervene if it detects a vehicle ahead
which is leaving the roundabout.
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.Lane Change By Other Vehicles
Vehicles suddenly changing lane,
entering the driving lane of the vehicle
and inside the radar sensor operating
range, may cause system activation.Vehicles Traveling At Right Angles
To The Vehicle
The system may temporarily react to a
vehicle that is passing through the radar
sensor’s operating range at right
angles.
Warning!
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.

Caution!
The TPMS has been optimized for the
original equipment tires and wheels. TPMS
pressures and warning have been
established for the tire size equipped on
your vehicle. Undesirable system operation
or sensor damage may result when using
replacement equipment that is not of the
same size, type, and/or style. Aftermarket
wheels can cause sensor damage.
Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. After
using an aftermarket tire sealant it is
recommended that you take your vehicle to
an authorized dealership to have your
sensor function checked.
After inspecting or adjusting the tire
pressure always reinstall the valve stem
cap. This will prevent moisture and dirt
from entering the valve stem, which could
damage the TPMS sensor.
INSUFFICIENT TIRE PRESSURE
INDICATION
If an insufficient pressure value is
detected on one or more tires, the
warning light in the instrument
cluster will display alongside the
dedicated messages, the system will
highlight the tire or tires with insufficient
pressure graphically, and an acoustic
signal will be emitted. In this case, stop the car, check the
inflation pressure of each tire, and
inflate the necessary tire or tires to the
correct cold inflation pressure value,
shown on the display or in the
dedicated TPMS menu.
TPMS TEMPORARILY DISABLED
TPMS Check Message
When a system fault is detected, the
“Tire Pressure Monitoring Telltale Light”
will flash on and off for 75 seconds, and
then remain on solid. The system fault
will also sound a chime. If the ignition is
cycled, this sequence will repeat,
provided that the system fault still
exists. The “Tire Pressure Monitoring
Telltale Light” will turn off when the fault
condition no longer exists. A system
fault can occur due to any of the
following:
Jamming due to electronic devices
or driving next to facilities emitting the
same radio frequencies as the TPMS
sensors.
Installing some form of aftermarket
window tinting that affects radio wave
signals.
Lots of snow or ice around the
wheels or wheel housings.
Using tire chains on the vehicle.
Using wheels/tires not equipped with
TPMS sensors. After the punctured tire has been
repaired with the original tire 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 all four wheel and tire
assemblies (road tires) with wheel and
tire assemblies that do not have TPMS
Sensors, such as when installing winter
wheel and tire assemblies on your
vehicle.
To deactivate the TPMS, first replace all
four wheel and tire assemblies (road
tires) with tires not equipped with Tire
Pressure Monitoring (TPM) Sensors.
Then, drive the vehicle for 10 minutes
above 15 mph (24 km/h). The TPMS
will chime, the "TPM Telltale Light" will
flash on and off for 75 seconds and
then remain on. The instrument cluster
will display the “SERVICE TPM
SYSTEM” message and then display
dashes (--) in place of the pressure
values.
Beginning with the next ignition switch
cycle, the TPMS will no longer chime or
display the “SERVICE TPM SYSTEM”
message in the instrument cluster.
Instead, dashes (--) will remain in place
of the pressure values.
To reactivate the TPMS, replace all four
wheel and tire assemblies (road tires)
with tires equipped with TPM sensors.

Supplemental Restraint
Systems (SRS)
Some of the safety features described
in this section may be standard
equipment on some models, or may be
optional equipment on others. If you are
not sure, ask your authorized dealer.
The air bag system must be ready to
protect you in a collision. The Occupant
Restraint Controller (ORC) monitors the
internal circuits and interconnecting
wiring associated with the electrical Air
Bag System Components. Your vehicle
may be equipped with the following Air
Bag System Components:
Air Bag System Components
Occupant Restraint Controller (ORC)
Air Bag Warning Light
Steering Wheel and Column
Instrument Panel
Knee Impact Bolsters
Driver and Front Passenger Air Bags
Supplemental Side Air Bags
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
Seat Belt Buckle Switch
Air Bag Warning Light
The ORC monitors the readiness of
the electronic parts of the air bag
system whenever the ignition switch is
in the AVV/START or ON/RUN position.
If the ignition switch is in the STOP
position or in the ON/RUN position, the
air bag system is not on and the air
bags will not inflate.
The ORC contains a backup power
supply system that may deploy the air
bag system even if the battery loses
power or it becomes disconnected
prior to deployment.
The ORC turns on the Air Bag Warning
Light in the instrument panel for
approximately four to eight seconds for a
self-check when the ignition switch is first
in the ON/RUN position. After the
self-check, the Air Bag Warning Light will
turn off. If the ORC detects a malfunction
in any part of the system, it turns on the
Air Bag Warning Light, either
momentarily or continuously. A single
chime will sound to alert you if the light
comes on again after initial startup.
The ORC also includes diagnostics that
will illuminate the instrument panel Air
Bag Warning Light if a malfunction is
detected that could affect the air bag
system. The diagnostics also record the
nature of the malfunction. While the air
bag system is designed to be
maintenance free, if any of the following
occurs, have an authorized dealer
service the air bag system immediately.
The Air Bag Warning Light does not
come on during the four to eight
seconds when the ignition is first in the
ON/RUN position.
The Air Bag Warning Light remains
on after the four to eight-second
interval.
The Air Bag Warning Light comes on
intermittently or remains on while
driving.
Note:
If the speedometer, tachometer, or any
engine related gauges are not working,
the Occupant Restraint Controller
(ORC) may also be disabled. In this
condition the air bags may not be ready
to inflate for your protection. Have an
authorized dealer service the air bag
system immediately.
Warning!
Ignoring the Air Bag Warning Light in your
instrument panel could mean you won’t
have the air bag system to protect you in a
collision. If the light does not come on as a
bulb check when the ignition is first turned
on, stays on after you start the vehicle, or if
it comes on as you drive, have an
authorized dealer service the air bag
system immediately.
115

Redundant Air Bag Warning
Light
If a fault with the Air Bag Warning
Light is detected, which could affect the
Supplemental Restraint System (SRS),
the Redundant Air Bag Warning Light
will illuminate on the instrument panel.
The Redundant Air Bag Warning Light
will stay on until the fault is cleared. In
addition, a single chime will sound to
alert you that the Redundant Air Bag
Warning Light has come on and a fault
has been detected. If the Redundant Air
Bag Warning Light comes on
intermittently or remains on while driving
have an authorized dealer service the
vehicle immediately. For additional
information regarding the Redundant Air
Bag Warning Light, refer to “Warning
Lights And Messages” in the “Getting to
Know Your Instrument Panel” section of
this manual.
Front Air Bags
This vehicle has front air bags and
lap/shoulder belts for both the driver
and front passenger. The front air bags
are a supplement to the seat belt
restraint systems. The driver front air
bag is mounted in the center of the
steering wheel. The passenger front air
bag is mounted in the instrument panel,
above the glove compartment. The
words “SRS AIRBAG” or “AIRBAG” are
embossed on the air bag covers.
Warning!
Being too close to the steering wheel or
instrument panel during front air bag
deployment could cause serious injury,
including death. Air bags need room to
inflate. Sit back, comfortably extending
your arms to reach the steering wheel or
instrument panel.
Never place a rear-facing child restraint
in front of an air bag. A deploying
passenger front air bag can cause death or
serious injury to a child 12 years or
younger, including a child in a rear-facing
child restraint.
Only use a rear-facing child restraint in a
vehicle with a rear seat.
Driver And Passenger Front Air
Bag Features
The Advanced Front Air Bag system
has multistage driver and front
passenger air bags. This system
provides output appropriate to the
severity and type of collision as
determined by the Occupant Restraint
Controller (ORC), which may receive
information from the front impact
sensors (if equipped) or other system
components.
The first stage inflator is triggered
immediately during an impact that
requires air bag deployment. A low
energy output is used in less severe
06106S0001EMDriver Air Bag
06106S0002EMPassenger Air Bag
116
SAFETY

collisions. A higher energy output is
used for more severe collisions.
This vehicle may be equipped with a
driver and/or front passenger seat belt
buckle switch that detects whether the
driver or front passenger seat belt is
buckled. The seat belt buckle switch
may adjust the inflation rate of the
Advanced Front Air Bags.
This vehicle may be equipped with
driver and/or front passenger seat track
position sensors that may adjust the
inflation rate of the Advanced Front Air
Bags based upon seat position.
Warning!
No objects should be placed over or
near the air bag on the instrument panel or
steering wheel because any such objects
could cause harm if the vehicle is in a
collision severe enough to cause the air
bag to inflate.
Do not put anything on or around the air
bag covers or attempt to open them
manually. You may damage the air bags
and you could be injured because the air
bags may no longer be functional. The
protective covers for the air bag cushions
are designed to open only when the air
bags are inflating.
Relying on the air bags alone could lead
to more severe injuries in a collision. The air
bags work with your seat belt to restrain
you properly. In some collisions, air bags
won’t deploy at all. Always wear your seat
belts even though you have air bags.
Front Air Bag Operation
Front Air Bags are designed to provide
additional protection by supplementing
the seat belts. Front air bags are not
expected to reduce the risk of injury in
rear, side, or rollover collisions. The front
air bags will not deploy in all frontal
collisions, including some that may
produce substantial vehicle damage —
for example, some pole collisions, truck
underrides, and angle offset collisions.
On the other hand, depending on the
type and location of impact, front air
bags may deploy in crashes with little
vehicle front-end damage but that
produce a severe initial deceleration.
Because air bag sensors measure
vehicle deceleration over time, vehicle
speed and damage by themselves are
not good indicators of whether or not
an air bag should have deployed.
Seat belts are necessary for your
protection in all collisions, and also are
needed to help keep you in position,
away from an inflating air bag. When the ORC detects a collision
requiring the front air bags, it signals the
inflator units. A large quantity of
non-toxic gas is generated to inflate the
front air bags.
The steering wheel hub trim cover and
the upper right side of the instrument
panel separate and fold out of the way
as the air bags inflate to their full size.
The front air bags fully inflate in less
time than it takes to blink your eyes.
The front air bags then quickly deflate
while helping to restrain the driver and
front passenger.
Knee Impact Bolsters
The Knee Impact Bolsters help protect
the knees of the driver and front
passenger, and position the front
occupants for improved interaction with
the front air bags.
Warning!
Do not drill, cut, or tamper with the knee
impact bolsters in any way.
Do not mount any accessories to the
knee impact bolsters such as alarm lights,
stereos, citizen band radios, etc.
