2018 Alfa Romeo Giulia sensor

Operating Example
For example, your vehicle may have a
recommended cold (parked for more than
three hours) placard pressure of 33 psi
(227 kPa). If the ambient temperature is
68°F (20°C), and the measured tire
pressure is 28 psi (193 kPa), a
temperature drop to 20°F (-7°C) will
decrease the tire pressure to
approximately 24 psi (165 kPa). This tire
pressure is low enough to turn on the
“Tire Pressure Monitoring Warning Light.”
Driving the vehicle may cause the tire
pressure to rise to approximately 28 psi
(193 kPa), but the “Tire Pressure
Monitoring Telltale Light” will still be on.
In this situation, the “Tire Pressure
Monitoring Warning Light” will turn off
only after the tires are inflated to the
vehicle’s recommended cold placard
pressure value.
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. The TPM
sensor is not designed for use on
aftermarket wheels and may contribute to a
poor overall system performance or sensor damage. Customers are encouraged to use
OEM wheels to assure proper TPM feature
operation.
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
your authorized dealer 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 vehicle, 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.
Accumulation 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 Tire Repair Kit, the
previous condition must be restored so
that the
warning light is off during
normal driving.

SAFETY

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 20 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.
Then, drive the vehicle for up to
20 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 turn off. The instrument cluster will
display the “SERVICE TPM SYSTEM”
message and then display pressure
values in place of the dashes. On the next ignition switch cycle the "SERVICE TPM
SYSTEM" message will no longer be
displayed, as long as no system fault
exists.
Note:
The TPMS is not intended to replace
normal tire care and maintenance, or to
provide warning of a tire failure or
condition.
The TPMS should not be used as a
tire pressure gauge while adjusting your
tire pressure.
Driving on a significantly
underinflated tire will cause the tire to
overheat, and can lead to tire failure.
Underinflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle’s handling and
stopping ability.
The TPMS is not a substitute for
proper tire maintenance, and it is the
driver’s responsibility to maintain
correct tire pressure using an accurate
tire pressure gauge, even if
underinflation has not reached the level
to trigger illumination of the “Tire
Pressure Monitoring Telltale Light”.
Seasonal temperature changes will
affect tire pressure, and the TPMS will
monitor the actual tire pressure in the
tire.

How To Disengage The Automatic
Locking Mode
Unbuckle the combination lap/shoulder
belt and allow it to retract completely to
disengage the Automatic Locking Mode
and activate the vehicle sensitive
(emergency) locking mode.
Warning!
The seat belt assembly must be replaced
if the switchable Automatic Locking
Retractor (ALR) feature or any other seat
belt function is not working properly when
checked according to the procedures in the
Service Manual.
Failure to replace the seat belt assembly
could increase the risk of injury in collisions.
Do not use the Automatic Locking Mode to
restrain occupants who are wearing the seat
belt or children who are using booster seats.
The locked mode is only used to install
rear-facing or forward-facing child restraints
that have a harness for restraining the child.
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 an 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
Seat Belt Buckle Switch
Supplemental Side Air Bags
Supplemental Knee Air Bags
Front and Side Impact Sensors
Seat Belt Pretensioners
Seat Track Position Sensors
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
START or ON/RUN position. If the ignition
switch is in the OFF position or in the ACC
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 switch is first in the
ON/RUN position.
The Air Bag Warning Light remains on
after the four to eight-second interval.
108
SAFETY

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.
Never install a rear-facing child restraint
in the front seat of a vehicle. Only use a
rear-facing child restraint in the rear seat.
If the vehicle does not have a rear seat, do
not transport a rear-facing child restraint in
that vehicle.
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
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.
110
SAFETY

The SAB moves at a very high speed and
with such a high force that it could injure
occupants if they are not seated
properly, or if items are positioned in the
area where the SAB inflates. Children are
at an even greater risk of injury from a
deploying air bag.
Warning!
Do not use accessory seat covers or place
objects between you and the Side Air Bags;
the performance could be adversely
affected and/or objects could be pushed into
you, causing serious injury.
Supplemental Side Air Bag Inflatable
Curtains (SABICs)
This vehicle is equipped with
Supplemental Side Air Bag Inflatable
Curtains (SABICs).
Supplemental Side Air Bag Inflatable
Curtains (SABICs) are located above the
side windows. The trim covering the
SABICs is labeled “SRS AIRBAG” or
“AIRBAG.”SABICs may help reduce the risk of head
and other injuries to front and rear seat
outboard occupants in certain side
impacts, in addition to the injury
reduction potential provided by the seat
belts and body structure.
The SABIC deploys downward, covering
the side windows. An inflating SABIC
pushes the outside edge of the headliner
out of the way and covers the window.
The SABICs inflate with enough force to
injure occupants if they are not belted
and seated properly, or if items are
positioned in the area where the SABICs
inflate. Children are at an even greater
risk of injury from a deploying air bag.
The SABICs may help reduce the risk of
partial or complete ejection of vehicle
occupants through side windows in
certain side impact events.
Warning!
Do not mount equipment, or stack luggage
or other cargo up high enough to block the
deployment of the SABICs. The trim covering
above the side windows where the SABIC and
its deployment path are located should
remain free from any obstructions.
Inorder for the SABICs to work as intended,
do not install any accessory items in your
vehicle which could alter the roof. Do not add
an aftermarket sunroof to your vehicle.
Do not add roof racks that require permanent
attachments (bolts or screws) for installation
on the vehicle roof. Do not drill into the roof of
the vehicle for any reason.
Side Impacts
The Side Air Bags are designed to
activate in certain side impacts. The
Occupant Restraint Controller (ORC)
determines whether the deployment of
the Side Air Bags in a particular impact
event is appropriate, based on the
severity and type of collision. The side
impact sensors aid the ORC in
determining the appropriate response to
impact events. The system is calibrated
to deploy the Side Air Bags on the impact
side of the vehicle during impacts that
require Side Air Bag occupant protection.
In side impacts, the Side Air Bags deploy
independently; a left side impact deploys
the left Side Air Bags only and a
right-side impact deploys the right Side
06106S0005EMSupplemental Side Air Bag Inflatable Curtain (SABIC) Location
112
SAFETY

Air Bags only. Vehicle damage by itself is
not a good indicator of whether or not
Side Air Bags should have deployed.
The Side Air Bags will not deploy in all
side collisions, including some collisions
at certain angles, or some side collisions
that do not impact the area of the
passenger compartment. The Side Air
Bags may deploy during angled or offset
frontal collisions where the front air bags
deploy.
Side Air Bags are a supplement to the
seat belt restraint system. Side Air Bags
deploy in less time than it takes to blink
your eyes.
Warning!
Occupants, including children, who are up
against or very close to Side Air Bags can be
seriously injured or killed. Occupants,
including children, should never lean on or
sleep against the door, side windows, or
area where the side air bags inflate, even if
they are in an infant or child restraint.
Seat belts (and child restraints where
appropriate) are necessary for your
protection in all collisions. They also help
keep you in position, away from an inflating
Side Air Bag. To get the best protection
from the Side Air Bags, occupants must
wear their seat belts properly and sit
upright with their backs against the seats.
Children must be properly restrained in a
child restraint or booster seat that is
appropriate for the size of the child.
Warning!
Side Air Bags need room to inflate. Do not
lean against the door or window. Sit upright
in the center of the seat.
Being too close to the Side Air Bags
during deployment could cause you to be
severely injured or killed.
Relying on the Side Air Bags alone could
lead to more severe injuries in a collision.
The Side Air Bags work with your seat belt
to restrain you properly. In some collisions,
Side Air Bags won’t deploy at all. Always
wear your seat belt even though you have
Side Air Bags.
Note: Air bag covers may not be obvious
in the interior trim, but they will open
during air bag deployment.
Rollover Events
Side Air Bags are designed to activate in
certain rollover events. The ORC
determines whether the deployment of
the Side Air Bags in a particular rollover
event is appropriate, based on the
severity and type of collision. Vehicle
damage by itself is not a good indicator
of whether or not Side Air Bags should
have deployed.
The Side Air Bags will not deploy in all
rollover events. The rollover sensing
system determines if a rollover event
may be in progress and whether
deployment is appropriate. In the event the vehicle experiences a rollover or near
rollover event, and deployment of the
Side Air Bags is appropriate, the rollover
sensing system will also deploy the seat
belt pretensioners on both sides of the
vehicle.
The SABICs may help reduce the risk of
partial or complete ejection of vehicle
occupants through side windows in
certain rollover or side impact events.

System Activation
The activation of the system is indicated
by the
symbol lighting up on the
display. In this condition, the light on the
button is off.
System Deactivation
A message will appear on the display
when the system is deactivated. In this
condition, the light on the button is on.
Note: Each time the engine is started,
the system is activated regardless of
where was when it was previously
switched off.
Possible Reasons The Engine Does Not
Autostop
For higher comfort and increased safety,
and to reduce emissions, there are
certain conditions where the engine will
not autostop despite the system being
active, such as:
Engine still cold.
Especially cold outside temperature.
Battery not sufficiently charged.
Driver's door not shut.
Driver's seat belt not fastened.
Reverse gear engaged (e.g. for parking
maneuvers).
With the automatic climate control
active, an adequate cabin heating or
cooling comfort has not been reached or
with MAX-DEF function active.
During the first period of use, to
initialize the system.
Steering angle beyond threshold.
Engine Restarting Conditions
Due to comfort, emission control and
safety reasons, the engine can restart
automatically without any action by the
driver, under special conditions, such as:
Battery not sufficiently charged.
Reduced braking system vacuum (e.g.
if the brake pedal is pressed repeatedly).
Vehicle moving (e.g. when driving on
roads with a grade).
Engine stopping by the Stop/Start
system for more than approx. three
minutes.
With the automatic climate control
active, an adjustment in cabin heating or
cooling is made or with MAX-DEF
function active.
Safety Functions
When the engine is stopped through the
Stop/Start system, if the driver releases
their seat belt, opens the driver's or
passenger's door, or opens the hood from
inside the vehicle, the engine can be
restarted only by using the ignition.
This condition is indicated to the driver
both through a buzzer and a message on
the instrument cluster display.
Irregular Operation
In the event of malfunction, the
Stop/Start system is deactivated.
For failure indications, see the "Warning
Lights and Messages" paragraph,
"Getting To Know Your Instrument Panel"
chapter.
Vehicle Inactivity
In the event of vehicle inactivity (or if the
battery is replaced), special attention
must be paid to the disconnection of the
battery power supply.
Proceed as follows:
Remove connector from socket to
disconnect sensor (battery status
monitoring) installed on the negative pole
of the battery. This sensor should never
be disconnected from the pole except if
the battery is replaced.
