NOTE:Driving with a hot engine cooling system could
damage your vehicle. The digital warning light may
switch on (together with a message on the display) to
indicate that the coolant temperature is too high; in this
case, stop the engine and contact a dedicated autho-
rized dealership.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer
for service if your vehicle overheats. If you decide
to look under the hood yourself, see “Servicing And
Maintenance.” Follow the warnings under the
Cooling System Pressure Cap paragraph.

•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

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:

to start within 10 seconds, turn the ignition switch to
the STOP (OFF/LOCK) position, wait 10 to 15 seconds,
then repeat the “Normal Starting” procedure.
Cold Weather Operation
Your engine is designed to operate at temperatures as
low as 0°F (-18°C).
CAUTION!
Use of the recommended oil and adhering to the
prescribed oil change intervals is important to pre-
vent engine damage and ensure satisfactory starting
in cold conditions.
If Engine Fails To Start
WARNING!
Never pour fuel or other flammable liquids into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in a flash fire causing
serious personal injury.
CAUTION!
•Do not attempt to push or tow your vehicle to get
it started. Vehicles equipped with a Alfa Twin
Clutch Transmission cannot be started this way.
Unburned fuel could enter the catalytic converter
and once the engine has started, ignite and dam-
age the converter and vehicle.
• To prevent damage to the starter, do not continu-
ously crank the engine for more than 15 seconds
at a time. Wait 10 to 15 seconds before trying
again.
After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
Turbo Charger “Cool Down”
This vehicle is equipped with an after-run pump to cool
the turbocharger after the engine is shut off. Depending
on the type of driving and the amount of cargo, the
pump will run for up to five minutes after the engine
has been shut off to circulate coolant through the
turbocharger.
130 STARTING AND OPERATING

If there is not a jet of fluid, first check that there is fluid
in the washer reservoir. Refer to “Adding Washer
Solvent” in this chapter for further information.
Then check that the nozzle holes are not clogged; use a
suitable tool such as a needle to unblock them if
necessary.
Exhaust System
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine ex-
haust system.
If you notice a change in the sound of the exhaust
system; or if the exhaust fumes can be detected inside
the vehicle; or when the underside or rear of the vehicle
is damaged; have an authorized technician inspect the
complete exhaust system and adjacent body areas for
broken, damaged, deteriorated, or mispositioned parts.
Open seams or loose connections could permit exhaust
fumes to seep into the passenger compartment. In
addition, have the exhaust system inspected each time
the vehicle is raised for lubrication or oil change.
Replace as required.
WARNING!
•Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you unconscious
and can eventually poison you. To avoid breath-
ing CO, refer to “Safety Tips” in “Safety” for
further information.
• A hot exhaust system can start a fire if you park
over materials that can burn. Such materials
might be grass or leaves coming into contact with
your exhaust system. Do not park or operate your
vehicle in areas where your exhaust system can
contact anything that can burn.
CAUTION!
• The catalytic converter requires the use of un-
leaded fuel only. Leaded gasoline will destroy the
effectiveness of the catalyst as an emissions con-
trol device and may seriously reduce engine per-
formance and cause serious damage to the engine.
• Damage to the catalytic converter can result if
your vehicle is not kept in proper operating

condition. In the event of engine malfunction,
particularly involving engine misfire or other
apparent loss of performance, have your vehicle
serviced promptly. Continued operation of your
vehicle with a severe malfunction could cause the
converter to overheat, resulting in possible dam-
age to the converter and vehicle.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is
important to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
NOTE: Intentional tampering with emissions control
systems can result in civil penalties being assessed
against you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe
and abnormal catalyst overheating. If this occurs, stop
the vehicle, turn off the engine and allow it to cool.
Service, including a tune-up to manufacturer’s specifi-
cations, should be obtained immediately.
To minimize the possibility of catalytic converter damage:
• Do not shut off the engine or interrupt the ignition,
when the transmission is in gear and the vehicle is in
motion.
• Do not try to start the engine by pushing or towing
the vehicle.
• Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough
idle or malfunctioning operating conditions.
Cooling System
WARNING!
• Turn vehicle off and disconnect the fan motor
lead before working near the radiator cooling fan.
•
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had
time to cool. Never open a cooling system pressure
cap when the radiator or coolant bottle is hot.

SERVICING AND MAINTENANCE 207

If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symp-
toms:
•Operate in a lean mode.
• OBD II “Malfunction Indicator Light” on.
• Poor engine performance.
• Poor cold start and cold drivability.
• Increased risk for fuel system component corrosion.
CNG And LP Fuel System Modifications
Modifications that allow the engine to run on com-
pressed natural gas (CNG) or liquid propane (LP) may
result in damage to the engine, emissions, and fuel
system components. Problems that result from running
CNG or LP are not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl
(MMT) is a manganese-containing metallic additive
that is blended into some gasoline to increase octane.
Gasoline blended with MMT provides no performance
advantage beyond gasoline of the same octane number without MMT. Gasoline blended with MMT reduces
spark plug life and reduces emissions system perfor-
mance in some vehicles. The manufacturer recom-
mends that gasoline without MMT be used in your
vehicle. The MMT content of gasoline may not be
indicated on the gasoline pump; therefore, you should
ask your gasoline retailer whether the gasoline contains
MMT. MMT is prohibited in Federal and California
reformulated gasoline.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•
The use of leaded gasoline is prohibited by Fed-
eral law. Using leaded gasoline can impair engine
performance and damage the emissions control
system.
• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate
