BLUE INDICATOR LIGHTS
High Beam Indicator Light
This indicator light will illuminate to indicate
that the high beam headlights are on. With
the low beams activated, push the multifunc-
tion lever forward (toward the front of the
vehicle) to turn on the high beams. Pull the multifunc-
tion lever rearward (toward the rear of the vehicle) to
turn off the high beams. If the high beams are off, pull
the lever toward you for a temporary high beam on,
"flash to pass" scenario.
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 trans-
mission control systems. When these systems are oper-
ating properly, your vehicle will provide excellent perfor-
mance and fuel economy, as well as engine emissions
well within current government regulations.
If any of these systems require service, the OBD II sys-
tem 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.
CAUTION!
•
Prolonged driving with the MIL on could cause fur-
ther 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 OBD II and a connec-
tion port to allow access to information related to the
performance of your emissions controls. Authorized
service technicians may need to access this informa-
tion to assist with the diagnosis and service of your
vehicle and emissions system
page 181.
WARNING!
•
ONLY an authorized service technician should con-
nect equipment to the OBD II connection port in
order to read the VIN, diagnose, or service your
vehicle.
(Continued)
WARNING!
•
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, information
stored in your vehicle systems, including per-
sonal information.
EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal requirement to pass
an inspection of your vehicle's emissions control sys-
tem. Failure to pass could prevent vehicle registration.
For states and/or provinces that require an
Inspection and Maintenance (I/M), this
check verifies the Malfunction Indicator Light
(MIL) is functioning and is not on when the
engine is running, and that the OBD II system is ready
for testing.
The OBD II system may
not
be ready if your vehicle was
recently serviced, recently had a depleted battery or a
battery replacement. If the OBD II system should be
determined not ready for the I/M test, your vehicle may
fail the test.
