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.

4

GETTING TO KNOW YOUR INSTRUMENT PANEL 69

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

70 GETTING TO KNOW YOUR INSTRUMENT PANEL

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 been

detected, 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

“Safety” for further information.

— Transmission Fault Warning Light

This light will illuminate (together with a message in

the instrument cluster display and a buzzer) to indicate

a transmission fault. Contact your authorized dealer if

the message remains after restarting the engine.

— Battery Charge Warning Light — If

Equipped
This light illuminates when the battery is not charging

properly. If it stays on while the engine is running, there

4

GETTING TO KNOW YOUR INSTRUMENT PANEL 71

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 upon

subsequent 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

(Continued)

CAUTION! (Continued)

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.

76 GETTING TO KNOW YOUR INSTRUMENT PANEL

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:

GETTING TO KNOW YOUR INSTRUMENT PANEL 77

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 not be 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.

78 GETTING TO KNOW YOUR INSTRUMENT PANEL

3. Approximately 15 seconds later, one of two things

will happen:

• The MIL will flash for about ten seconds and then

return to being fully illuminated until you turn OFF

the ignition or start the engine. This means that your

vehicle’s OBD II system is not ready and you should

not

proceed to the I/M station.

• The MIL will not flash at all and will remain fully

illuminated until you place the ignition in the off

position or start the engine. This means that your

vehicle’s OBD II system is ready and you can proceed

to the I/M station.

If your OBD II system is not ready, you should see your

authorized dealer or repair facility. If your vehicle was

recently serviced or had a battery failure or replace-

ment, you may need to do nothing more than drive

your vehicle as you normally would in order for your

OBD II system to update. A recheck with the above test

routine may then indicate that the system is now ready.
Regardless of whether your vehicle’s OBD II system is

ready or not, if the MIL is illuminated during normal

vehicle operation you should have your vehicle ser-

viced before going to the I/M station. The I/M station

can fail your vehicle because the MIL is on with the

engine running.

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

(Continued)

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.
