WARNING LIGHTS AND MESSAGES
The warning/indicator lights switch on in the instru-
ment panel together with a dedicated message and/or
acoustic signal when applicable. These indications are
indicative and precautionary and as such must not be
considered as exhaustive and/or alternative to the
information contained in the Owner ’s Manual, which
you are advised to read carefully in all cases. Always
refer to the information in this chapter in the event of a
failure indication. All active telltales will display first if
applicable. The system check menu may appear differ-
ent based upon equipment options and current vehicle
status. Some telltales are optional and may not appear.
Red Warning Lights
— Brake Warning Light
This light monitors various brake functions, including
brake fluid level and parking brake application. If the
brake light turns on it may indicate that the parking brake is applied, that the brake fluid level is low, or that
there is a problem with the anti-lock brake system
reservoir.
If the light remains on when the parking brake has been
disengaged, and the fluid level is at the full mark on the
master cylinder reservoir, it indicates a possible brake
hydraulic system malfunction or that a problem with
the Brake Booster has been detected by the Anti-Lock
Brake System (ABS) / Electronic Stability Control (ESC)
system. In this case, the light will remain on until the
condition has been corrected. If the problem is related to
the brake booster, the ABS pump will run when apply-
ing the brake, and a brake pedal pulsation may be felt
during each stop.
The dual brake system provides a reserve braking
capacity in the event of a failure to a portion of the
hydraulic system. A leak in either half of the dual brake
system is indicated by the Brake Warning Light, which
will turn on when the brake fluid level in the master
cylinder has dropped below a specified level.
The light will remain on until the cause is corrected.

GETTING TO KNOW YOUR INSTRUMENT PANEL 77

NOTE:The light may flash momentarily during sharp
cornering maneuvers, which change fluid level condi-
tions. The vehicle should have service performed, and
the brake fluid level checked.
If brake failure is indicated, immediate repair is neces-
sary.
WARNING!
Driving a vehicle with the red brake light on is
dangerous. Part of the brake system may have
failed. It will take longer to stop the vehicle. You
could have a collision. Have the vehicle checked
immediately.
Vehicles equipped with the Anti-Lock Brake System
(ABS) are also equipped with Electronic Brake Force
Distribution (EBD). In the event of an EBD failure, the
Brake Warning Light will turn on along with the ABS
Light. Immediate repair to the ABS system is required.
Operation of the Brake Warning Light can be checked
by turning the ignition switch from the OFF position to
the ON/RUN position. The light should illuminate for
approximately two seconds. The light should then turn
off unless the parking brake is applied or a brake fault is detected. If the light does not illuminate, have the
light inspected by your authorized dealer.
The light also will turn on when the parking brake is
applied with the ignition switch in the ON/RUN posi-
tion.
NOTE:
This light shows only that the parking brake is
applied. It does not show the degree of brake applica-
tion.— Oil Pressure Warning Light
This light indicates low engine oil pressure. If the light
turns on while driving, stop the vehicle and shut off the
engine as soon as possible. A chime will sound when
this light turns on.
Do not operate the vehicle until the cause is corrected.
This light does not indicate how much oil is in the
engine. The engine oil level must be checked under the
hood.
— Electronic Throttle Control (ETC) Warning
Light
This light informs you of a problem with the Electronic
Throttle Control (ETC) system. If a problem is detected
while the vehicle is running, the light will either stay on

sensor to become inoperable. After using an after-
market tire sealant it is recommended that you take
your vehicle to your authorized dealer to have your
sensor function checked.
— Anti-Lock Brake (ABS) Warning Light
This light monitors the Anti-Lock Brake System (ABS).
The light will turn on when the ignition is placed in the
ON/RUN or MAR/ON/RUN position and may stay
on for as long as four seconds.
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 Indicator
Light” come on momentarily each time the ignition 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.

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 condi-
tions. 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.
90 SAFETY

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

SAFETY 91

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.
92 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.
