Light (MIL) is a part of an Onboard
Di
agnostic System called OBD II that
monitors engine and automatic
transmission control systems. This warning light
will illuminate when the ignition is in the ON/RUN
position before engine start. If the bulb does not
come on when turning the ignition switch from OFF
to ON/RUN, have the condition checked promptly.
Certain conditions, such as a loose or missing gas
c a

p, poor quality fuel, etc., may illuminate the light
after engine start. The vehicle should be serviced if
the light stays on through several typical driving
styles. In most situations, the vehicle will drive
normally and will not require towing.

GETTING TO KNOW YOUR INSTRUMENT PANEL 79
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
sy

stem 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.
ONBOARD DIAGNOSTIC SYSTEM
(OBD II) C
YBERSECURITY
Your vehicle is required to have an 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 121.
EMISSIONS INSPECTION AND
MAINTENANCE PROGRAMS
In some localities, it may be a legal requirement to
pass an inspection of your vehicle's emissions
control system. Failure to pass could prevent
vehicle registration.
For states that require an Inspection and
Maintenance (I/M), this check verifies
th

e 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.
Normally, the OBD II system will be ready. The
OBD II system may n
ot
be ready if your vehicle was
recently serviced, recently had a dead 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.
Your vehicle has a simple ignition actuated test,
w h

ich you can use prior to going to the test station.
To check if your vehicle's OBD II system is ready,
you must do the following:

1. Cycle the ignition switch to the ON position, b
ut do not crank or start the engine.

NOTE:
If you crank or start the engine, you will have to
s t
art this test over.
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.
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,
i n
cluding personal information.

This feature allows the driver to operate the
ignition switch with the push of a button, as long as
the Remote Start/Keyless Enter ‘n Go™ key fob is
in the passenger compartment.
NORMAL STARTING
To Turn On The Engine Using The ENGINE START/
STOP Button

1. The transmission must be in PARK.

2

. P ress and hold the brake pedal while pushing
t
he ENGINE START/STOP button once.
3. The system takes over and attempts to start t

WARNING!
When exiting the vehicle, always make sure
the ignition is in OFF mode, remove the key
fob from the vehicle and lock the vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving chil -
dren in a vehicle unattended is dangerous for
a

number of reasons. A child or others could
be seriously or fatally injured. Children should
be warned not to touch the parking brake,
brake pedal or the transmission gear selector.
Do not leave the key fob in or near the vehicle
(or in a location accessible to children), and do
not leave the ignition (of a vehicle equipped
with Keyless Enter ‘n Go™) in the ACC or ON/
RUN mode. A child could operate power
windows, other controls, or move the vehicle.
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat build-up
may cause serious injury or death.
CAUTION!
Shift into or out of PARK or REVERSE only after
the vehicle has come to a complete stop.
Do not shift between PARK, REVERSE,
NEUTRAL, or DRIVE when the engine is above
idle speed.
Before shifting into any gear, make sure your
foot is firmly pressing the brake pedal.

AUTOPARK
AutoPark is a supplemental feature to assist in
placing the vehicle in PARK should the situations
on the following pages occur. It is a back up system
and should not be relied upon as the primary
method by which the driver shifts the vehicle into
PARK.
The conditions under which AutoPark will engage
ar
e outlined on the following pages. If the vehicle is not in PARK and the driver turns off
t
h

e engine, the vehicle may AutoPark.
AutoPark will engage when all of these conditions
ar
e met:
Vehicle is equipped with a rotary selector and an
eight speed transmission
Vehicle is not in PARK
Vehicle speed is 1.2 mph (1.9 km/h) or less
Ignition switched from RUN to ACC
WARNING!
Driver inattention could lead to failure to place
the vehicle in PARK. ALWAYS DO A VISUAL
CHECK that your vehicle is in PARK by verifying
that a solid (not blinking) “P” is indicated in
the instrument cluster display and near the
gear selector. If the “P” indicator is blinking,
your vehicle is not in PARK. As an added
precaution, always apply the parking brake
when exiting the vehicle.
AutoPark is a supplemental feature. It is not
designed to replace the need to shift your
vehicle into PARK. It is a back up system and
should not be relied upon as the primary
method by which the driver shifts the vehicle
into PARK.
