brake light Alfa Romeo 4C 2017 User Guide

CAUTION!
If the Brake Warning Light remains on with the
parking brake released, a brake system malfunction
is indicated. Have the brake system serviced by an
authorized dealer immediately.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems loses
normal capability, the remaining system will still func-
tion. However, there will be some loss of overall brak-
ing effectiveness. You may notice increased pedal travel
during application, greater pedal force required to slow
or stop, and potential activation of the “Brake System
Warning Light”.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off), the
brakes will still function. However, the effort required
to brake the vehicle will be much greater than that
required with the power system operating.
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

150 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.
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 sur-
faces.
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
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.
(Continued)
152 STARTING AND OPERATING

WARNING!(Continued)
•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.
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.
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.

STARTING AND OPERATING 153

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.
• 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.

may result in unsatisfactory engine coolant (anti-
freeze) performance, poor gas mileage, and increased
emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and
possibly a collision. Driving with your foot resting
or riding on the brake pedal can result in abnor-
mally high brake temperatures, excessive lining
wear, and possible brake damage. Riding the
brakes may also reduce braking capacity in an
emergency.
Brake Master Cylinder
The fluid level in the master cylinder should be checked
when performing under hood services, or immediately
if the “Brake Warning Light” is on.Be sure to clean the top of the master cylinder area
before removing the cap. If necessary, add fluid to bring
the fluid level up to the requirements described on the
brake fluid reservoir. Fluid level can be expected to fall
as the brake pads wear. The brake fluid level should be
checked when the pads are replaced. However, low
fluid level may be caused by a leak and a checkup may
be needed.
Use only manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, And Genuine Parts” in
“Maintaining Your Vehicle” for further information.
WARNING!
•
Use only manufacturer’s recommended brake
fluid. Refer to “Fluids, Lubricants, And Genuine
Parts” in “Maintaining Your Vehicle” for further
information. Using the wrong type of brake fluid
can severely damage your brake system and/or
impair its performance. The proper type of brake
fluid for your vehicle is also identified on the
original factory installed hydraulic master cylin-
der reservoir.
