Night Vision Warning System status is
Suppressed Ú page 178.
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
transmission control systems. When these systems are
operating properly, your vehicle will provide excellent
performance and fuel economy, as well as engine
emissions 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 driveable 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.
If the MIL is flashing while the vehicle is

running, severe catalytic converter damage
and power loss will soon occur. Immediate
service is required.

NBOARD IAGNOSTIC YSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have 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 Ú page 202.
WARNING!
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:
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, infor-

mation stored in your vehicle systems,
including personal information.
