Yellow Warning Lights
— Engine Check/Malfunction Indicator Warning
Light (MIL)
The Engine Check/Malfunction Indicator Light (MIL) is a
part of an Onboard Diagnostic System called OBD II that
monitors engine and automatic transmission control sys-
tems. 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 cap, 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 ve-
hicle will drive normally and will not require towing.
When the engine is running, the MIL may flash to alert
serious conditions that could lead to immediate loss of
power or severe catalytic converter damage. The vehicle
should be serviced by an authorized dealer as soon as
possible if this occurs.

WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal
operating conditions. This can cause a fire if you drive
slowly or park over flammable substances such as dry
plants, wood, cardboard, etc. This could result in death
or serious injury to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the vehicle
control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.
— Electronic Stability Control (ESC) Active
Warning Light — If Equipped
This warning light will indicate when the Electronic Sta-
bility Control system is Active. The “ESC Indicator Light”
in the instrument cluster will come on when the ignition is
placed in the ON/RUN or ACC/ON/RUN position, and
when ESC is activated. It should go out with the engine running. If the “ESC Indicator Light” comes on continu-
ously with the engine running, a malfunction has been
detected in the ESC system. If this warning light remains
on after several ignition cycles, and the vehicle has been
driven several miles (kilometers) at speeds greater than
30 mph (48 km/h), see an authorized dealer as soon as
possible to have the problem diagnosed and corrected.
•
The “ESC Off Indicator Light” and the “ESC Indicator
Light” come on momentarily each time the ignition is
placed in the ON/RUN or ACC/ON/RUN position.
• The ESC system will make buzzing or clicking sounds
when it is active. This is normal; the sounds will stop
when ESC becomes inactive.
• This light will come on when the vehicle is in an ESC
event.
— Electronic Stability Control (ESC) Off Warning
Light — If Equipped
This warning light indicates the Electronic Stability Control
(ESC) is off.
Each time the ignition is turned to ON/RUN or ACC/ON/
RUN, the ESC system will be on, even if it was turned off
previously.

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 prop-
erly, 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 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 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 ac-
cess this information to assist with the diagnosis and
service of your vehicle and emissions system.
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

Keyless Enter-N-Go — Ignition
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.
Cold Weather Operation (Below –22°F Or 30°C)
To ensure reliable starting at these temperatures, use of an
externally powered electric engine block heater (available
from your authorized dealer) is recommended.
If Engine Fails To Start
If the engine fails to start after you have followed the
Normal Starting orExtreme Cold Weather procedure it
may be flooded. Push the accelerator pedal all the way to
the floor and hold it there. Crank the engine for no more
than 15 seconds. This should clear any excess fuel in case
the engine is flooded. Leave the ignition key in the RUN
position, release the accelerator pedal and repeat the “Nor-
mal Starting” procedure.
WARNING!
• Never pour fuel or other flammable liquid into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in flash fire causing
serious personal injury.
• Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.

232 STARTING AND OPERATING

CAUTION!
•The catalytic converter requires the use of unleaded
fuel only. Leaded gasoline will destroy the effective-
ness of the catalyst as an emissions control device
and may seriously reduce engine performance and
cause serious damage to the engine.
•
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. In the
event of engine malfunction, particularly involving
engine misfire or other apparent loss of performance,
have your vehicle serviced promptly. Continued opera-
tion of your vehicle with a severe malfunction could
cause the converter to overheat, resulting in possible
damage to the converter and vehicle.
Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to assure proper catalyst
operation and prevent possible catalyst damage.
NOTE:
Intentional tampering with emissions control sys-
tems can result in civil penalties being assessed against you.
In unusual situations involving grossly malfunctioning
engine operation, a scorching odor may suggest severe and
abnormal catalyst overheating. If this occurs, stop the
vehicle, turn off the engine and allow it to cool. Service,
including a tune-up to manufacturer’s specifications,
should be obtained immediately.
To minimize the possibility of catalytic converter damage:
• Do not shut off the engine or interrupt the ignition when
the transmission is in gear and the vehicle is in motion.
• Do not try to start the engine by pushing or towing the
vehicle.
• Do not idle the engine with any spark plug wires
disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.
NOTE: Your vehicle’s exhaust system may be equipped
with an Electronic Exhaust Valve (EEV) system, if the
exhaust system is replaced with aftermarket products a
Malfunction Indicator Lamp (MIL) will illuminate.

Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gasoline is prohibited by Federal
law. Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system.
• An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune or
malfunctioning and may require immediate service.
Contact an authorized dealer for service assistance.
• The use of fuel additives, which are now being sold
as octane enhancers, is not recommended. Most of
these products contain high concentrations of metha-
nol. Fuel system damage or vehicle performance
problems resulting from the use of such fuels or
additives is not the responsibility of the manufac-
turer and may void or not be covered under the New
Vehicle Limited Warranty. NOTE:
Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon mon-
oxide poisoning:
• Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle
is stopped in an open area with the engine running
for more than a short period, adjust the ventilation
system to force fresh, outside air into the vehicle.
• Guard against carbon monoxide with proper main-
tenance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi-
tions repaired promptly. Until repaired, drive with
all side windows fully open.
