2019 Alfa Romeo 4C Spider ABS

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

•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

Race Mode
Activation
Starting in Dynamic mode, move the Alfa DNA system
lever upwards (to the letter “D”) and hold in this
position for five seconds, until the Race mode activation
indicator appears on the display.
When Race mode is activated, the longitudinal/lateral
accelerometer indicator screen (G-meter information) is
displayed automatically. This considers gravitational
acceleration (G).
Electronic Stability Control (ESC) and Anti-Slip
Regulation (ASR) systems:
These systems are deactivated in order to ensure the
fullest sensation of sport, leaving the driver in full
control of the vehicle. When the vehicle is in unstable
conditions, the ESC reactivates automatically when the
brake pedal is pressed until the ABS intervenes, thus
returning the vehicle to stable conditions. To deactivate
the ESC and ASR systems, reactivate Race mode.
Electronic Q2 system:
The system increases vehicle stability while accelerating
on bends, improving the agility of the vehicle.Engine And Gearbox/Transmission:
The system adjusts the transmission shift calibration for
sportier shifting.
NOTE:
In Race mode, the sensitivity of the accelerator
pedal increases considerably. Consequently, driving is
less fluid and comfortable.
In Race mode, the transmission only works in
MANUAL mode.
Deactivation
To deactivate Race mode and return to Dynamic mode,
move the Alfa DNA system lever downwards (to letter
“A”) and keep it in this position for half a second.
The LED corresponding to Dynamic mode will light up
and the Dynamic mode activation indication will ap-
pear on the display.
Natural Mode
Electronic Stability Control (ESC) and Anti-Slip
Regulation (ASR) systems:
ESC and ASR system thresholds are aimed at providing
comfort and safety in normal grip and driving condi-
tions.

Tire Service Kit Components And Operation
WARNING!
•Do not attempt to seal a tire on the side of the
vehicle closest to traffic. Pull far enough off the
road to avoid the danger of being hit when using
the Tire Service Kit.
• Do not use Tire Service Kit or drive the vehicle
under the following circumstances:
– If the puncture in the tire tread is approxi- mately 1/4 inch (6 mm) or larger.
– If the tire has any sidewall damage.
– If the tire has any damage from driving with extremely low tire pressure.
– If the tire has any damage from driving on a flat tire.
– If the wheel has any damage.
– If you are unsure of the condition of the tire or the wheel.
• Keep Tire Service Kit away from open flames or
heat source.
(Continued)
WARNING! (Continued)
•A loose Tire Service Kit thrown forward in a
collision or hard stop could endanger the occu-
pants of the vehicle. Always stow the Tire Service
Kit in the place provided. Failure to follow these
warnings can result in injuries that are serious or
fatal to you, your passengers, and others around
you.
• Take care not to allow the contents of Tire Service
Kit to come in contact with hair, eyes, or clothing.
Tire Service Kit sealant is harmful if inhaled,
swallowed, or absorbed through the skin. It
causes skin, eye, and respiratory irritation. Flush
immediately with plenty of water if there is any
contact with eyes or skin. Change clothing as soon
as possible, if there is any contact with clothing.
• Tire Service Kit Sealant solution contains latex. In
case of an allergic reaction or rash, consult a
physician immediately. Keep Tire Service Kit out
of reach of children. If swallowed, rinse mouth
immediately with plenty of water and drink
plenty of water. Do not induce vomiting! Consult
a physician immediately.
182 IN CASE OF EMERGENCY

Use only manufacturer’s recommended brake fluid.
Refer to “Fluids And Lubricants ” in “Technical Speci-
fications” for further information.
WARNING!
•Use only manufacturer’s recommended brake
fluid. Refer to “Fluids And Lubricants” in “Tech-
nical Specifications” for further information. Us-
ing the wrong type of brake fluid can severely
damage your brake system and/or impair its per-
formance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.
• To avoid contamination from foreign matter or
moisture, use only new brake fluid or fluid that
has been in a tightly closed container. Keep the
master cylinder reservoir cap secured at all times.
Brake fluid in a open container absorbs moisture
from the air resulting in a lower boiling point.
This may cause it to boil unexpectedly during
hard or prolonged braking, resulting in sudden
brake failure. This could result in a collision.
(Continued)
WARNING! (Continued)
•Overfilling the brake fluid reservoir can result in
spilling brake fluid on hot engine parts, causing
the brake fluid to catch fire. Brake fluid can also
damage painted and vinyl surfaces, care should
be taken to avoid its contact with these surfaces.
• Do not allow petroleum based fluid to contami-
nate the brake fluid. Brake seal components could
be damaged, causing partial or complete brake
failure. This could result in a collision.
CAUTION!
Use of improper brake fluids will affect overall
clutch system performance. Improper brake fluids
may damage the clutch system resulting in loss of
clutch function and the ability to shift the transmis-
sion.
