2019 Alfa Romeo 4C Spider lock

If the ABS light remains on or turns on while driving,
then the Anti-Lock portion of the brake system is not
functioning and service is required. However, the con-
ventional brake system will continue to operate nor-
mally if the brake warning light is not on.
If the ABS light is on, the brake system should be
serviced as soon as possible to restore the benefits of
Anti-Lock Brakes. If the ABS light does not turn on
when the ignition is placed in the ON/RUN or MAR/
ON/RUN position, have the light inspected by an
authorized dealer.
— Electronic Stability Control (ESC) Warning
Light — If Equipped
The “ESC Indicator Light” in the instrument cluster will
come on when the ignition is placed in the ON/RUN or
MAR/ON/RUN position, and when ESC is activated. It
should go out with the engine running. If the “ESC
Indicator Light” comes on continuously with the engine
running, a malfunction has been detected in the ESC
system. If this light remains on after several ignition
cycles, and the vehicle has been driven several miles
(kilometers) at speeds greater than 30 mph (48 km/h),
see your authorized dealer as soon as possible to have
the problem diagnosed and corrected. •
The “ESC Off Indicator Light” and the “ESC Indica-
tor Light” come on momentarily each time the igni-
tion is placed in the ON/RUN or MAR/ON/RUN
position.
• Each time the ignition is turned to ON/RUN or
MAR/ON/RUN, the ESC system will be on, even if
it was turned off previously.
• The ESC system will make buzzing or clicking
sounds when it is active. This is normal; the sounds
will stop when ESC becomes inactive.
• This light will come on when the vehicle is in an ESC
event.— Electronic Stability Control (ESC) Off
Warning Light — If Equipped
This warning light indicates the Electronic Stability
Control (ESC) is off.
Each time the ignition is turned to ON/RUN or ACC/
ON/RUN, the ESC system will be on, even if it was
turned off previously.

SAFETY FEATURES
Four-Wheel Anti-Lock Brake System (ABS)
The Four-Wheel ABS is designed to aid the driver in
maintaining vehicle control under adverse braking con-
ditions. The system operates with a separate computer to
modulate hydraulic pressure, to prevent wheel lock-up
and to help avoid skidding on slippery surfaces.
The system’s pump motor runs during an ABS stop to
provide regulated hydraulic pressure. The pump motor
makes a low humming noise during operation, which is
normal.
The ABS includes an amber ABS Warning Light. When
the light is illuminated, the ABS is not functioning. The
system reverts to standard non-anti-lock brakes. Turn-
ing the ignition OFF and ON again may reset the ABS if
the fault detected was only momentary.
WARNING!
•When the ABS intervenes and you feel the brake
pedal pulsating, do not reduce the pressure, but
hold it down firmly and confidently; in doing so
(Continued)
WARNING! (Continued)
you will brake in the shortest distance possible,
depending on the current road conditions.
• For maximum efficiency of the braking system, a
bedding-in period of about 311 miles (500 km) is
required: during this period it is advisable to
avoid sharp, repeated and prolonged braking.
• If the ABS intervenes, this indicates that the grip
of the tires on the road is nearing its limit: you
must slow down to a speed compatible with the
available grip.
• The ABS can’t overrule the natural laws of phys-
ics, and can’t increase the grip available according
to the condition of the road.
• The ABS cannot prevent accidents, including
those due to excessive speed on corners, driving
on low-grip surfaces or aquaplaning.
•
The capability of the ABS must never be tested
irresponsibly and dangerously, in such a way as to
compromise personal safety and the safety of others.
• For the correct operation of the ABS, the tires
must of necessity be the same make and type on
all wheels, in perfect condition and, above all, of
the prescribed type and dimensions.
88 SAFETY

WARNING!(Continued)
inflated and unevenly worn tires may also de-
grade ESC performance. Any vehicle modifica-
tion 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.
The ESC system uses sensors installed on the vehicle to
determine the trajectory that the driver intends to
follow and compares it with the vehicles effective
trajectory. When the real trajectory deviates from the
desired trajectory, the ESC system intervenes to counter
the vehicles understeer or oversteer.
• Oversteer: occurs when the vehicle 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.
This vehicle’s advanced electronic brake control system
also includes: Electronic Brake Distribution (EBD), Anti-
Lock Brake System (ABS), Cornering Brake Control
System (CBC), Drag Torque Control System (DTC), AntiSlip Regulation System (ASR), Hill Start Assist
(HSA), Hydraulic Brake Assistant System (HBA),
ELECTRONIC Q2 system (E-Q2) and Ready Alert Brake
(RAB). All of the systems work together to enhance
vehicle stability and control in various driving condi-
tions, and are commonly referred to as ESC.
System Activation
The ESC system activates automatically when the en-
gine is started and can only be deactivated by selecting
Race
mode. Refer to the Six-Speed Alfa Twin Clutch
Transmission in “Starting And Operating.”
System Intervention
This is indicated by the flashing of the warning light on
the instrument panel, to inform the driver that the
vehicle is in critical stability and grip conditions.
Electronic Brake Distribution System (EBD)
The EBD system is an integral part of the ESC system
and intervenes during braking, distributing the brake
force optimally between front and rear wheels.
This guarantees greater braking stability for the vehicle,
preventing sudden locking of the rear wheels and the
consequent instability of the vehicle.
90 SAFETY

Cornering Brake Control System (CBC)
The system acts when braking on corners, optimizing the
distribution of brake pressure on the four wheels: the
system prevents the wheels on the inside of the corner
(less affected by the weight of the vehicle) from locking,
ensuring better stability and direction for the vehicle.
Drag Torque Control System (DTC)
This is an integral part of the ESC system and inter-
venes in the event of sudden downshifting, or during
braking when the ABS intervenes, restoring torque to
the engine and thus preventing excessive drag at the
drive wheels, which may lead the wheels to lock and a
loss of vehicle stability, above all in low-grip conditions.
AntiSlip Regulation System (ASR)
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 pre-
vent all collisions, including those resulting from
(Continued)
WARNING! (Continued)
excessive speed in turns, driving on very slippery
surfaces, or hydroplaning. ESC also cannot pre-
vent collisions resulting from loss of vehicle
control due to inappropriate driver input for the
conditions. Only a safe, attentive, and skillful
driver can prevent collisions. 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 nega-
tively affect the performance of the ESC system.
Changes to the steering system, suspension, brak-
ing system, tire type and size or wheel size may
adversely affect ESC performance. Improperly
inflated and unevenly worn tires may also de-
grade ESC performance. Any vehicle modifica-
tion 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.

SAFETY 91

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 an autho-
rized dealer. FCA US LLC does not recommend deacti-
vating 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.
• It is dangerous to ride in a cargo area, inside or
outside of a vehicle. In a collision, people riding
in these areas are more likely to be seriously
injured or killed.
•
Do not allow people to ride in any area of your
vehicle that is not equipped with seats and seat
belts.

SAFETY 101

Seat Belt Pretensioner
The front outboard seat belt system is equipped with
pretensioning 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.
Pretensioners 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
The front outboard seat belt system is equipped with an
Energy Management feature that may help further
reduce the risk of injury in the event of a collision. The
seat belt system has a retractor assembly that is de-
signed 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.
ALR — Switchable Automatic Locking Retractor
106 SAFETY

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 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
(Continued)
WARNING! (Continued)
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.
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.
