2019 Alfa Romeo 4C Spider brake light

When you are in a severe braking condition involving
the use of the ABS, you will experience some pedal drop
as the vehicle comes to a stop. This is the result of the
system reverting to the base brake system.
Engagement of the ABS may be accompanied by a
pulsing sensation. You may also hear a clicking noise.
These occurrences are normal and indicate that the
system is functioning properly.
System Intervention
A slight pulsing of the brake pedal and noise indicates
the intervention of the ABS: this is completely normal
when the system intervenes.
ESC (Electronic Stability Control System)
The ESC system improves the directional control and
stability of the vehicle in various driving conditions.
The ESC system corrects the vehicle understeer and
oversteer, distributing the brake force on the appropri-
ate wheels. The torque supplied by the engine can also
be reduced in order to maintain control of the vehicle.
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
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

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

This is an integral part of the ESC system and automati-
cally operates in the event of one or both drive wheels
slipping, loss of grip on wet roads (hydroplaning) and
acceleration on slippery, snowy or icy roads, etc.
Depending on the slipping conditions, two different
control systems are activated:
•If the slipping involves both drive wheels, the ASR
system intervenes, reducing the power transmitted
by the engine.
• If the slipping only involves one of the drive wheels,
it also intervenes automatically, braking the wheel
that is slipping.
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.
Hill Start Assist (HSA)
This is an integral part of the ESC system and facilitates
starting on slopes, activating automatically in the fol-
lowing cases: •
Uphill: vehicle stationary on a road with a gradient
higher than 5%, engine running, brake pressed and
transmission in neutral (N) or gear other than reverse
engaged.
• Downhill: vehicle stationary on a road with a gradi-
ent higher than 5%, engine running, brake pressed
and reverse (R) gear engaged.
When setting off, the ESC system control unit maintains
the braking pressure on the wheels until the engine
torque necessary for starting is reached, or in any case
for a maximum of two seconds, allowing your right foot
to be moved easily from the brake pedal to the accel-
erator.
When the two seconds have elapsed, without starting,
the system is automatically deactivated, gradually re-
leasing the braking pressure. During this release stage,
the typical brake disengagement noise, indicating that
the vehicle is going to move imminently, can be heard.
NOTE:
• HSA is not a parking brake; therefore, never leave the
vehicle without having engaged the parking brake,
turned the engine off and engaged first gear, so that
the vehicle is parked in safe conditions.
92 SAFETY

•There may be situations on small gradients (less than
8%), with vehicle laden, in which the Hill Holder
system may not activate, causing a slight reversing
motion and increasing the risk of collision with
another vehicle or object. The driver is, in any case,
responsible for safe driving.
Hydraulic Brake Assistant System (HBA)
WARNING!
• The HBA system can’t overrule the natural laws
of physics, and can’t increase the grip available
according to the condition of the road.
• The HBA system cannot prevent accidents, in-
cluding those due to excessive speed on corners,
driving on low-grip surfaces or aquaplaning.
•
The capability of the HBA system must never be
tested irresponsibly and dangerously, in such a way
as to compromise the safety of the driver, the other
occupants of the vehicle or any other road user.
The HBA system is designed to improve the vehicles
braking capacity during emergency braking. The sys-
tem detects emergency braking by monitoring the
speed and force with which the brake pedal is pressed, and consequently applies the optimal brake pressure.
This can reduce the braking distance, the HBA system
therefore completes the ABS.
Maximum assistance from the HBA system is obtained
pressing the brake pedal very quickly. In addition, the
brake pedal should be pressed continuously during
braking, avoiding intermittent presses, to get the most
out of the system.
Do not reduce pressure on the brake pedal until braking
is no longer necessary.
The HBA system is deactivated when the brake pedal is
released.
Electronic Q2 System (E-Q2)
The
Electronic Q2 system intervenes during accelera-
tion on corners, braking the inner drive wheel and thus
increasing the traction of the outer wheel (which bears
more of the vehicles weight): the torque is thus distrib-
uted optimally between the drive wheels in accordance
with the driving conditions and road surface, permit-
ting particularly effective, sporty driving.

SAFETY 93

Ready Alert Brake System (RAB)
This function activates automatically if the accelerator
pedal is released rapidly, reducing the brake pad travel
(both at front and back), with the aim of preparing the
braking system and enhancing its responsiveness, thus
reducing the stopping distance in the event of subse-
quent braking.
AUXILIARY DRIVING SYSTEMS
Tire Pressure Monitoring System (TPMS)
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle
recommended cold tire pressure.
The tire pressure will vary with temperature by about
1 psi (7 kPa) for every 12°F (6.5°C). This means that
when the outside temperature decreases, the tire pres-
sure will decrease. Tire pressure should always be set
based on cold inflation tire pressure. This is defined as
the tire pressure after the vehicle has not been driven
for at least three hours, or driven less than 1 mile
(1.6 km) after a three hour period. The cold tire inflation
pressure must not exceed the maximum inflation pres-
sure molded into the tire sidewall. Refer to “Tires” in
“Servicing And Maintenance” for information on howto properly inflate the vehicle’s tires. The tire pressure
will also increase as the vehicle is driven - this is normal
and there should be no adjustment for this increased
pressure.
The TPMS will warn the driver of a low tire pressure if
the tire pressure falls below the low pressure warning
limit for any reason, including low temperature effects,
or natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not
turn off until the tire pressure is at or above the
recommended cold placard pressure. Once the low tire
pressure warning (TPMS Warning Light) illuminates,
you must increase the tire pressure to the recommended
cold placard pressure in order for the TPMS Warning
Light to turn off. The system will automatically update
and the TPMS Warning Light will turn off once the
system receives the updated tire pressures. 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.
For example, your vehicle may have a recommended
cold (parked for more than three hours) placard pres-
sure of 30 psi (207 kPa). If the ambient temperature is

Air Bag Warning Light
The Air Bag warning lightwill turn on for four to
eight seconds as a bulb check when the ignition
switch is first turned to ON/RUN. If the light is
either not on during starting, stays on, or turns on
while driving, have the system inspected at an
authorized dealer as soon as possible. After the bulb
check, this light will illuminate with a single chime
when a fault with the Air Bag System has been
detected. It will stay on until the fault is removed. If
the light comes on intermittently or remains on while
driving, have an authorized dealer service the ve-
hicle immediately.
Refer to “Occupant Restraint Systems” in “Safety” for
further information.
Defroster
Check operation by selecting the defrost mode and
place the blower control on high speed. You should be
able to feel the air directed against the windshield. See
an authorized dealer for service if your defroster is
inoperable.
