Engine Check/Malfunction Indicator Light (MIL)
Yellow TelltaleLight What It Means
Engine Check/Malfunction Indicator 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 control systems. The
light will illuminate when the ignition is in the MAR/ON/RUN position before engine start.
If the bulb does not come on when turning the key from STOP/OFF/LOCK to MAR/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 sev-
eral 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 ser-
viced 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 engine
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.

engine fails 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” proce-
dure.
Cold Weather Operation
Your engine is designed to operate at temperatures as
low as 0°F (-18°C).
CAUTION!
Use of the recommended SAE 5W-40 Synthetic oil
and adhering to the prescribed oil change intervals
is important to prevent 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.

Designated TOP TIER Detergent
Gasoline contains a higher level of
detergents to further aide in minimiz-
ing engine and fuel system deposits.
When available, the usage of Top Tier
Detergent gasoline is recommended.
Visit www.toptiergas.com for a list of
TOP TIER Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning agents
should be avoided. Many of these materials intended
for gum and varnish removal may contain active sol-
vents or similar ingredients. These can harm fuel sys-
tem gasket and diaphragm materials.
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.
(Continued)
CAUTION! (Continued)
•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
service. Contact your authorized dealer for service
assistance.
• The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
Most of these products contain high concentra-
tions of methanol. Fuel system damage or vehicle
performance problems resulting from the use of
such fuels or additives is not the responsibility of
the manufacturer and may void or not be covered
under the New Vehicle Limited Warranty.
NOTE: Intentional tampering with the emissions con-
trol system can result in civil penalties being assessed
against you.
186 STARTING AND OPERATING

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 pro-
vide excellent performance and fuel economy, as well as
engine emissions well within current government regu-
lations.
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.
• If the MIL is flashing while the engine is running,
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.
210 MAINTAINING YOUR VEHICLE

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/Exhaust Gas” in
“Things To Know Before Starting Your Vehicle”
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.
(Continued)
CAUTION! (Continued)
•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 dam-
age:
•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.
