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

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.
Cooling System

• Turn vehicle off and disconnect the fan motor
lead before working near the radiator cooling fan.

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.
• Keep hands, tools, clothing, and jewelry away
from the radiator cooling fan when the hood is
raised. The fan starts automatically and may start
at any time, whether the engine is running or not.
• When working near the radiator cooling fan,
disconnect the fan motor lead or turn the ignition
switch to the OFF position. The fan is temperature
controlled and can start at any time the ignition
switch is in the ON position.
• 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 try to open a cooling
system pressure cap when the radiator is hot.
