Gray Indicator Lights

Cruise Control Ready Indicator Light — If Equipped With
Base Instrument Cluster
This light will turn on when the speed control has
been turned on, but not set. Refer to "Speed Control
— If Equipped" in "Starting And Operating" for
further information.
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 trans-
mission control systems. When these systems are operating
properly, your vehicle will provide excellent performance
and fuel economy, as well as 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 drivable and not need towing, see an
authorized dealer for service as soon as possible.
GETTING TO KNOW YOUR INSTRUMENT PANEL
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.

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.
