2018 Alfa Romeo Stelvio sensors

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 Warning 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 Warning 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.
Packed 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 20 minutes
above 15 mph (24 km/h). The TPMS will
chime, the "TPMS Warning 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.
115

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 Warning
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 Warning Light”.
Seasonal temperature changes will
affect tire pressure, and the TPMS will
monitor the actual tire pressure in the
tire.

SAFETY

webbing to retract completely in this
case and then carefully pull out only the
amount of webbing necessary to
comfortably wrap around the occupant’s
mid-section. Slide the latch plate into the
buckle until you hear a "click."
In Automatic Locking Mode, the shoulder
belt is automatically pre-locked. The seat
belt will still retract to remove any slack
in the shoulder belt. Use the Automatic
Locking Mode anytime a child restraint is
installed in a seating position that has a
seat belt with this feature. Children
12 years old and under should always be
properly restrained in the rear seat of a
vehicle with a rear seat.
Warning!
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
the rear seat of a vehicle with a rear seat.
How To Engage The Automatic Locking
Mode
1. Buckle the combination lap and
shoulder belt. 2. Grasp the shoulder portion and pull
downward until the entire seat belt is
extracted.
3. Allow the seat belt to retract. As the
seat belt retracts, you will hear a clicking
sound. This indicates the seat belt is now
in the Automatic Locking Mode.
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 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:

SAFETY

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.
The steering wheel hub trim cover and
the upper passenger 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.
125

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.
In order 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
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.
127

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.

If A Deployment Occurs
The front air bags are designed to deflate
immediately after deployment.
Note: Front and/or side air bags will not
deploy in all collisions. This does not
mean something is wrong with the air bag
system. If you do have a collision which deploys
the air bags, any or all of the following
may occur:
The air bag material may sometimes
cause abrasions and/or skin reddening to
the occupants as the air bags deploy and
unfold. The abrasions are similar to
friction rope burns or those you might get
sliding along a carpet or gymnasium floor.
They are not caused by contact with
chemicals. They are not permanent and
normally heal quickly. However, if you
haven’t healed significantly within a few
days, or if you have any blistering, see
your doctor immediately.
As the air bags deflate, you may see
some smoke-like particles. The particles
are a normal by-product of the process
that generates the non-toxic gas used for
air bag inflation. These airborne particles
may irritate the skin, eyes, nose, or
throat. If you have skin or eye irritation,
rinse the area with cool water. For nose
or throat irritation, move to fresh air. If
the irritation continues, see your doctor.
If these particles settle on your clothing,
follow the garment manufacturer’s
instructions for cleaning.
Do not drive your vehicle after the air
bags have deployed. If you are involved in
another collision, the air bags will not be
in place to protect you.
