or flash depending on the nature of the problem. Cycle
the ignition when the vehicle is safely and completely
stopped and the transmission is placed in the PARK
position. The light should turn off. If the light remains
on with the vehicle running, your vehicle will usually
be drivable; however, see an authorized dealer for
service as soon as possible.
If the light continues to flash when the vehicle is
running, immediate service is required and you may
experience reduced performance, an elevated/rough
idle, or engine stall and your vehicle may require
towing. The light will come on when the ignition is
placed in the ON/RUN or MAR/ON/RUN position
and remain on briefly as a bulb check. If the light does
not come on during starting, have the system checked
by an authorized dealer.
— Air Bag Warning Light
This light will turn on for four to eight seconds as a bulb
check when the ignition is placed in the ON/RUN or
MAR/ON/RUN position. If the light is either not on
during startup, stays on, or turns on while driving, have
the system inspected at an authorized dealer as soon as
possible. This light will illuminate with a single chime
when a fault with the Air Bag Warning Light has beendetected, it will stay on until the fault is cleared. If the
light comes on intermittently or remains on while
driving, have an authorized dealer service the vehicle
immediately.
— Seat Belt Reminder Warning Light
When the ignition is first placed in the ON/RUN or
MAR/ON/RUN position, if the driver ’s seat belt is
unbuckled, a chime will sound and the light will turn
on. When driving, if the driver or front passenger seat
belt remains unbuckled, the Seat Belt Reminder Light
will flash or remain on continuously and a chime will
sound. Refer to “Occupant Restraints Systems” in

may be a malfunction with the charging system. Con-
tact your authorized dealer as soon as possible. This
indicates a possible problem with the electrical system
or a related component.
— Engine Coolant Temperature Warning Light
This light warns of an overheated engine condition. If
the engine coolant temperature is too high, this indica-
tor will illuminate and a single chime will sound. If the
temperature reaches the upper limit, a continuous
chime will be sound for four minutes or until the engine
is able to cool: whichever comes first.
If the light turns on while driving, safely pull over and
stop the vehicle. If the A/C system is on, turn it off.
Also, shift the transmission into NEUTRAL and idle the
vehicle. If the temperature reading does not return to
normal, turn the engine off immediately and call for
service. Refer to “If Your Engine Overheats” in “In Case
Of Emergency” for further information.
Yellow Warning Lights
— Tire Pressure Monitoring System (TPMS)
Warning Light
The warning light switches on and a message is dis-
played to indicate that the tire pressure is lower than the recommended value and/or that slow pressure loss
is occurring. In these cases, optimal tire duration and
fuel consumption may not be guaranteed.
Should one or more tires be in the condition mentioned
above, the display will show the indications corre-
sponding to each tire in sequence.
CAUTION!
Do not continue driving with one or more flat tires
as handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. If a tire punc-
ture occurs, repair immediately using the dedicated
tire repair kit and contact your authorized dealer as
soon as possible.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on
the vehicle placard or tire inflation pressure label. (If
your vehicle has tires of a different size than the size
indicated on the vehicle placard or tire inflation pres-
sure label, you should determine the proper tire infla-
tion pressure for those tires.)
72 GETTING TO KNOW YOUR INSTRUMENT PANEL

As an added safety feature, your vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly under-
inflated. Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible, and inflate them to the proper pres-
sure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation
has not reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is
not operating properly. The TPMS malfunction indica-
tor is combined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will flash
for approximately one minute and then remain continu-
ously illuminated. This sequence will continue uponsubsequent vehicle start-ups as long as the malfunction
exists. When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may occur for
a variety of reasons, including the installation of re-
placement or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning properly. Al-
ways check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function prop-
erly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)

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 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.
74 GETTING TO KNOW YOUR INSTRUMENT PANEL

•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

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.

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.
