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 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 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.
— Engine Check/Malfunction Indicator
Warning Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is
a part of an Onboard Diagnostic System called OBD II
that monitors engine and automatic transmission con-
trol systems. The light will illuminate when the ignition
is in the ON/RUN position before engine start. If the
bulb does not come on when turning the ignition switch
from OFF to ON/RUN, have the condition checked
promptly.
Certain conditions, such as a loose or missing gas cap,
poor quality fuel, etc., may illuminate the light after
engine start. The vehicle should be serviced if the light stays on through several typical driving styles. In most
situations, the vehicle will drive normally and will not
require towing.
When the engine is running, the MIL may flash to alert
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced as soon as possible if this occurs.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in nor-
mal operating conditions. This can cause a fire if
you drive slowly or park over flammable sub-
stances such as dry plants, wood, cardboard, etc.
This could result in death or serious injury to the
driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the vehicle
control system. It also could affect fuel economy
and driveability. If the MIL is flashing, severe

catalytic converter damage and power loss will soon
occur. Immediate service is required.
— Generic Warning Light
The Generic Warning Light will illuminate if there is an
Engine Oil Pressure Sensor Failure.
— Passenger Air Bag Indicator Light
This light should come and remain on for four to eight
seconds as a bulb check when the ignition is first turned
to the AVV/START or MAR/ON/RUN position. If the
light stays on, or comes on while driving it may indicate
a problem with a passenger air bag system, if the light
flickers it may indicate an air bag warning light failure.
Have an authorized dealer service the air bag system
immediately.
Green Indicator Lights
— Turn Signal Indicator Lights
The turn signal arrows will flash independently when
left or right turn signals are selected. Turn signals can be
activated when the multifunction lever is moved down
(left) or up (right).
— Park/Headlight On Indicator Light
This indicator will illuminate when the park lights or
headlights are turned on.
— Cruise Control Set Indicator Light — If
Equipped
This light will turn on when the speed control is set to
the desired speed. Refer to “Speed Control” in “Starting
And Operating” for further information.
— Door Mirror Defrost Indicator Light
This indicator will illuminate when the Door Mirror
Defrost button on the instrument panel is pushed to the
on position.
Blue Indicator Lights
— High Beam Indicator Light
This indicator shows that the high beam headlights are
on. With the low beams activated, push the multifunc-
tion lever forward (toward the front of the vehicle) to
turn on the high beams. Pull the multifunction lever
rearward (toward the rear of the vehicle) to turn off the
high beams. If the high beams are off, pull the lever
toward you for a temporary high beam on, flash to

ONBOARD DIAGNOSTIC SYSTEM — OBD II
Your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors the
performance of the emissions, engine, and Alfa Twin
Clutch Transmission control systems. When these systems
are operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine emis-
sions well within current government regulations.
If any of these systems require service, the OBD II
system will turn on the “Malfunction Indicator Light
(MIL)”. It will also store diagnostic codes and other
information to assist your service technician in making
repairs. Although your vehicle will usually be drivable
and not need towing, see your authorized dealer for
service as soon as possible.
CAUTION!
•Prolonged driving with the MIL on could cause
further damage to the emission control system. It
could also affect fuel economy and driveability.
The vehicle must be serviced before any emis-
sions tests can be performed.
(Continued)
CAUTION! (Continued)
•If the MIL is flashing while the vehicle is run-
ning, severe catalytic converter damage and
power loss will soon occur. Immediate service is
required.
Onboard Diagnostic System (OBD II)
Cybersecurity
Your vehicle is required to have an Onboard Diagnostic
system (OBD II) and a connection port to allow access to
information related to the performance of your emis-
sions controls. Authorized service technicians may need
to access this information to assist with the diagnosis
and service of your vehicle and emissions system.
WARNING!
• ONLY an authorized service technician should
connect equipment to the OBD II connection port
in order to diagnose or service your vehicle.
• If unauthorized equipment is connected to the
OBD II connection port, such as a driver-behavior
tracking device, it may:

WARNING!(Continued)
•Be possible that vehicle systems, including
safety related systems, could be impaired or a
loss of vehicle control could occur that may
result in an accident involving serious injury or
death.
• Access, or allow others to access, information
stored in your vehicle systems, including per-
sonal information.
For further information, refer to “Cybersecurity” in the
“Multimedia” section.
EMISSIONS INSPECTION AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle’s emissions control sys-
tem. Failure to pass could prevent vehicle registration. For states that require an Inspection and Main-
tenance (I/M), this check verifies the “Malfunc-
tion Indicator Light (MIL)” is functioning and is
not on when the engine is running, and that the OBD II
system is ready for testing. Normally, the OBD II system will be ready. The OBD II
system may
notbe ready if your vehicle was recently
serviced, recently had a dead battery or a battery
replacement. If the OBD II system should be deter-
mined not ready for the I/M test, your vehicle may fail
the test.
Your vehicle has a simple ignition actuated test, which
you can use prior to going to the test station. To check
if your vehicle’s OBD II system is ready, you must do
the following:
1. Cycle the ignition switch to the ON position, but do not crank or start the engine.
NOTE: If you crank or start the engine, you will have to
start this test over.
2. As soon as you cycle the ignition switch to the ON position, you will see the “Malfunction Indicator
Light (MIL)” symbol come on as part of a normal
bulb check.

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 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
(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.
(Continued)
82 SAFETY

WARNING!(Continued)
•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.
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

SAFETY 83

WARNING!(Continued)
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.
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.
