2017 Alfa Romeo 4C Owner's Manual

Lap/Shoulder Belt Untwisting Procedure
Use the following procedure to untwist a twisted lap/
shoulder belt.
1. Position the latch plate as close as possible to theanchor point.
2. At about 6 to 12 inches (15 to 30 cm) above the latch plate, grasp and twist the seat belt webbing 180
degrees to create a fold that begins immediately
above the latch plate.
3. Slide the latch plate upward over the folded web- bing. The folded webbing must enter the slot at the
top of the latch plate.
4. Continue to slide the latch plate up until it clears the folded webbing and the seat belt is no longer
twisted.
Seat Belts And Pregnant Women
Seat belts must be worn by all occupants including
pregnant women: the risk of injury in the event of an
accident is reduced for the mother and the unborn child
if they are wearing a seat belt.
Position the lap belt snug and low below the abdomen
and across the strong bones of the hips. Place the
shoulder belt across the chest and away from the neck.
Never place the shoulder belt behind the back or under
the arm.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 31

Seat Belt Pretensioner
The front seat belt system is equipped with pretension-
ing devices that are designed to remove slack from the
seat belt in the event of a collision. These devices may
improve the performance of the seat belt by removing
slack from the seat belt early in a collision. Pretension-
ers work for all size occupants, including those in child
restraints.
NOTE:These devices are not a substitute for proper
seat belt placement by the occupant. The seat belt still
must be worn snugly and positioned properly.
The pretensioners are triggered by the Occupant Re-
straint Controller (ORC). Like the air bags, the preten-
sioners are single use items. A deployed pretensioner or
a deployed air bag must be replaced immediately.
Energy Management Feature
This vehicle has a seat belt system with an Energy
Management feature in the front seating positions that
may help further reduce the risk of injury in the event of
a collision. This seat belt system has a retractor assem-
bly that is designed to release webbing in a controlled
manner.
Switchable Automatic Locking Retractor (ALR)
The seat belt in the passenger seating position is
equipped with a Switchable Automatic Locking Retrac-
tor (ALR) which is used to secure a child restraint
system. For additional information, refer to “Installing
Child Restraints Using The Vehicle Seat Belt” under the
“Child Restraints” section of this manual. The figure
below illustrates the locking feature for each seating
position.
Automatic Locking Retractor (ALR) Locations
32 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

If the passenger seating position is equipped with an
ALR and is being used for normal usage, only pull the
seat belt webbing out far enough to comfortably wrap
around the occupant’s mid-section so as to not activate
the ALR. If the ALR is activated, you will hear a clicking
sound as the seat belt retracts. Allow the webbing to
retract completely in this case and then carefully pull
out only the amount of webbing necessary to comfort-
ably wrap around the occupant’s mid-section. Slide the
latch plate into the buckle until you hear aclick.
In Automatic Locking Mode, the shoulder belt is auto-
matically pre-locked. The seat belt will still retract to
remove any slack in the shoulder belt. Use the Auto-
matic Locking Mode anytime a child restraint is in-
stalled in a seating position that has a seat belt with this
feature. Children 12 years old and under should always
be properly restrained in 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 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 (emer-
gency) locking mode.2
THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 33

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 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 System (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:

34 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

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/ON/RUN position. If the ignition
switch is in the STOP/OFF/LOCK 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 sec-
onds for a self-check when the ignition switch is in the
MAR/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 continu-
ously. 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 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 condi-
tion the air bags may not be ready to inflate for your
protection. Have an authorized dealer service the air
bag system immediately.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 35

WARNING!
Ignoring the Air Bag Warning Light in your instru-
ment panel could mean you won’t have the air bags
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

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 pro-
vides output appropriate to the severity and type of
collision as determined by the Occupant Restraint Con-
troller (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.

THINGS TO KNOW BEFORE STARTING YOUR VEHICLE 37

WARNING!(Continued)
•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.
