2018 Alfa Romeo 4C warning light

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 under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation 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 mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire gauge,
even if under-inflation has not reached the level to
trigger illumination of the Tire Pressure Monitoring
Telltale Light.
• Seasonal temperature changes will affect tire pres-
sure, and the TPMS will monitor the actual tire
pressure in the tire.Base System
This is the TPMS warning indicator located in
the instrument cluster.
The TPMS uses wireless technology with
wheel rim mounted electronic sensors to monitor tire
pressure levels. Sensors, mounted to each wheel as part
of the valve stem, transmit tire pressure readings to the
Receiver Module.
NOTE: It is particularly important for you to check the
tire pressure in all of the tires on your vehicle regularly
and to maintain the proper pressure.
The TPMS consists of the following components:
• Receiver Module.
• Four Tire Pressure Monitoring Sensors.
• Tire Pressure Monitoring Telltale Light.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illumi-
nate in the instrument cluster, an acoustic signal will be
activated, and the “Check left or right front/rear tire”
text message will display when one or more of the four
90 SAFETY

active road tire pressures are low. Should this occur, you
should stop as soon as possible, check the inflation
pressure of each tire on your vehicle, and inflate each
tire to the vehicle’s recommended cold placard pressure
value. The system will automatically update and the
Tire Pressure Monitoring Light will extinguish once the
updated tire pressures have been received. The vehicle
may need to be driven for up to 20 minutes above
15 mph (24 km/h) to receive this information.
Check TPMS Warnings
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and remain on solid when a
system fault is detected, the “TIRE PRESSURE MONI-
TORING UNAVAILABLE” text message will display. If
the ignition key is cycled, this sequence will repeat
providing 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
with any of the following scenarios:
1. Jamming due to electronic devices or driving next tofacilities emitting the same radio frequencies as the
TPM sensors.
2. Installing some form of aftermarket window tinting that affects radio wave signals. 3. Snow or ice around the wheels or wheel housings.
4. Using tire chains on the vehicle.
5. Using wheels/tires not equipped with TPM sensors.
NOTE:
Your vehicle may be equipped with a compact
spare wheel and tire assembly.
1. The compact spare tire does not have a tire pressure monitoring sensor. Therefore, the TPMS will not
monitor the tire pressure in the compact spare tire.
2. If you install the compact spare tire in place of a road tire that has a pressure below the low-pressure
warning limit, upon the next ignition key cycle, a
chime will sound and the Tire Pressure Monitoring
Telltale Light will still turn ON due to the low tire.
3. However, after driving the vehicle for up to 20 minutes above 15 mph (24 km/h), the Tire Pressure
Monitoring Telltale Light will flash on and off for 75
seconds and then remain on solid.
4. This occurs for each subsequent ignition key cycle, a chime will sound and the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds and
then remain on solid.

SAFETY 91

5. Once you repair or replace the original road tire andreinstall it on the vehicle in place of the compact
spare tire, the TPMS will update automatically and
the Tire Pressure Monitoring Telltale Light will turn
OFF, as long as no tire pressure is below the low-
pressure warning limit in any of the four active road
tires. The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.

OCCUPANT RESTRAINT SYSTEMS
Some of the most important safety features in your
vehicle are the restraint systems:
Occupant Restraint Systems Features
• Seat Belt Systems
• Supplemental Restraint Systems (SRS) Air Bags
• Child Restraints
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.
Important Safety Precautions
Please pay close attention to the information in this
section. It tells you how to use your restraint system
properly, to keep you and your passengers as safe as
possible.
Here are some simple steps you can take to minimize
the risk of harm from a deploying air bag:
1. Children 12 years old and under should always ride buckled up in a vehicle with a rear seat.
92 SAFETY

Research has shown that seat belts save lives, and they
can reduce the seriousness of injuries in a collision.
Some of the worst injuries happen when people are
thrown from the vehicle. Seat belts reduce the possibil-
ity of ejection and the risk of injury caused by striking
the inside of the vehicle. Everyone in a motor vehicle
should be belted at all times.
Enhanced Seat Belt Use Reminder System
(BeltAlert)
Driver and Passenger BeltAlert (if equipped)
BeltAlert is a feature intended to remind the
driver and outboard front seat passenger (if
equipped with outboard front passenger seat
BeltAlert) to buckle their seat belts. The Belt Alert
feature is active whenever the ignition switch is in
the START or ON/RUN position.
Initial Indication
If the driver is unbuckled when the ignition switch is
first in the START or ON/RUN position, a chime will
signal for a few seconds. If the driver or outboard front
seat passenger (if equipped with outboard front passen-
ger seat BeltAlert) is unbuckled when the ignition
switch is first in the START or ON/RUN position the Seat Belt Reminder Light will turn on and remain on
until both outboard front seat belts are buckled. The
outboard front passenger seat BeltAlert is not active
when an outboard front passenger seat is unoccupied.
BeltAlert Warning Sequence
The BeltAlert warning sequence is activated when the
vehicle is moving above a specified vehicle speed range
and the driver or outboard front seat passenger is
unbuckled (if equipped with outboard front passenger
seat BeltAlert) (the outboard front passenger seat
BeltAlert is not active when the outboard front passen-
ger seat is unoccupied). The BeltAlert warning se-
quence starts by blinking the Seat Belt Reminder Light
and sounding an intermittent chime. Once the BeltAlert
warning sequence has completed, the Seat Belt Re-
minder Light will remain on until the seat belts are
buckled. The BeltAlert warning sequence may repeat
based on vehicle speed until the driver and occupied
outboard front seat passenger seat belts are buckled.
The driver should instruct all occupants to buckle their
seat belts.
94 SAFETY

Change of Status
If the driver or outboard front seat passenger (if
equipped with outboard front passenger seat BeltAlert)
unbuckles their seat belt while the vehicle is traveling,
the BeltAlert warning sequence will begin until the seat
belts are buckled again.
The outboard front passenger seat BeltAlert is not active
when the outboard front passenger seat is unoccupied.
BeltAlert may be triggered when an animal or other
items are placed on the outboard front passenger seat or
when the seat is folded flat (if equipped). It is recom-
mended that pets be restrained in the rear seat (if
equipped) in pet harnesses or pet carriers that are
secured by seat belts, and cargo is properly stowed.
BeltAlert can be activated or deactivated by your au-
thorized dealer. FCA US LLC does not recommend
deactivating BeltAlert.
NOTE:If BeltAlert has been deactivated and the driver
or outboard front seat passenger (if equipped with
outboard front passenger seat BeltAlert) is unbuckled
the Seat Belt Reminder Light will turn on and remain on
until the driver and outboard front seat passenger seat
belts are buckled.Lap/Shoulder Belts
All seating positions in your vehicle are equipped with
lap/shoulder belts.
The seat belt webbing retractor will lock only during
very sudden stops or collisions. This feature allows the
shoulder part of the seat belt to move freely with you
under normal conditions. However, in a collision the
seat belt will lock and reduce your risk of striking the
inside of the vehicle or being thrown out of the vehicle.
WARNING!
• 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, the air bags won’t deploy at all.
Always wear your seat belt even though you have
air bags.
• In a collision, you and your passengers can suffer
much greater injuries if you are not properly
buckled up. You can strike the interior of your
vehicle or other passengers, or you can be thrown
out of the vehicle. Always be sure you and others
in your vehicle are buckled up properly.

How To Engage The Automatic Locking Mode
1. Buckle the combination lap and shoulder belt.
2. Grasp the shoulder portion and pull downward untilthe 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 (emer-
gency) 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.
(Continued)
WARNING! (Continued)
•Do not use the Automatic Locking Mode to re-
strain 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 har-
ness 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 wir-
ing associated with the electrical Air Bag System Com-
ponents. Your vehicle may be equipped with the fol-
lowing Air Bag System Components:
Air Bag System Components
• Occupant Restraint Controller (ORC)
• Air Bag Warning Light
102 SAFETY

•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 elec-
tronic parts of the air bag system whenever
the ignition switch is in the AVV/START or
MAR/ACC/ON/RUN position. If the igni-
tion switch is in the STOP/OFF/LOCK 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 sec-
onds for a self-check when the ignition switch is in the
MAR/ACC/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 mal-
function is detected that could affect the air bag system.
The diagnostics also record the nature of the malfunc-
tion. While the air bag system is designed to be main-
tenance 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 MAR/ACC/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.

SAFETY 103

NOTE:If the speedometer, tachometer, or any engine
related gauges are not working, the Occupant Restraint
Controller (ORC) may also be disabled. In this condi-
tion 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 instru-
ment 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.
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 instru-
ment panel during front air bag deployment
could cause serious injury, including death. Air
bags need room to inflate. Sit back, comfortably
