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 automatic transmis-
sion control systems. When these systems are
operating properly, your vehicle will provide
excellent performance and fuel economy, as
well as emissions well within current govern-
ment regulations.
If any of these systems require service, the
OBD II system will turn on the Malfunction
Indicator Light (MIL). It will also store diag-
nostic codes and other information to assist
your service technician in making repairs.
Although your vehicle will usually be drivable
and not need towing, see an 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 emissions
tests can be performed.

CAUTION! (Continued)
If the MIL is flashing while the vehicle is
running,
severe
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 emissions controls.
Authorized service technicians may need to
access this information to assist with the
diagnosis and service of your vehicle and
emissions system.
ONLY an authorized service technician
should connect equipment to the OBD II
connection port in order to read the VIN,
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:

an accident involving serious injury or
death.

EMISSIONS INSPECTION
AND MAINTENANCE
PROGRAMS
In some localities, it may be a legal require-
ment to pass an inspection of your vehicle's
emissions control system. Failure to pass
could prevent vehicle registration.
For states that require an Inspec-
tion and Maintenance (I/M) test,
