Engine Check/Malfunction Indicator Light (MIL)
Yellow TelltaleLight What It Means
Engine Check/Malfunction Indicator 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 systems. The 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 key 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 vehicle 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 im-
mediate loss of power or severe catalytic converter damage. The vehicle should be serviced 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 engine
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.

If Engine Fails To Start
CAUTION!
To prevent damage to the starter, do not crank the
engine for more than 15 seconds at a time. Wait 10 to 15
seconds before trying again.
WARNING!
•Never pour fuel or other flammable liquids into the
throttle body air inlet opening in an attempt to start
the vehicle. This could result in a flash fire causing
serious personal injury.
• Do not attempt to push or tow your vehicle to get it
started. Unburned fuel could enter the catalytic con-
verter and once the engine has started, ignite and
damage the converter and vehicle. If the vehicle has
a discharged battery, booster cables may be used to
obtain a start from a booster battery or the battery in
another vehicle. This type of start can be dangerous
if done improperly, so follow this procedure care-
fully. Refer to “Jump-Starting” in “What To Do In
Emergencies” for further information. If the engine is flooded, it may start to run, but not have
enough power to continue running when the ENGINE
START button is released. If this occurs, continue cranking
up to 15 seconds with the accelerator pedal pushed all the
way to the floor. Release the accelerator pedal and the
ENGINE START button once the engine is running
smoothly.
If the engine shows no sign of starting after two 15 second
periods of cranking with the accelerator pedal held to the
floor, the “Normal Starting” procedure should be repeated.
After Starting
The idle speed is controlled automatically, and it will
decrease as the engine warms up.
MANUAL TRANSMISSION
NOTE:
The parking brake should be engaged and the gear
selector placed into REVERSE before leaving the vehicle,
especially when parked on an incline.
Your vehicle is equipped with a high torque capacity dual
disc clutch. The clutch pedal must be fully pressed to the
floor during each shift. As you release the clutch pedal,
lightly press the accelerator pedal.
192 STARTING AND OPERATING

Materials Added To Fuel
Besides using unleaded gasoline with the proper octane
rating, gasolines that contain detergents, corrosion, and
stability additives are recommended. Using gasolines that
have these additives will help improve fuel economy,
reduce emissions, and maintain vehicle performance.Designated TOP TIER Detergent Gaso-
line contains a higher level of detergents
to further aide in minimizing engine
and fuel system deposits. When avail-
able, the usage of Top Tier Detergent
gasoline is recommended. Visit
www.toptiergas.com for a list of TOP
TIER Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning agents should be
avoided. Many of these materials intended for gum and
varnish removal may contain active solvents or similar
ingredients. These can harm fuel system gasket and dia-
phragm materials.
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 your 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.

JUMP-STARTING PROCEDURES
WARNING!
•Take care to avoid the radiator cooling fan whenever
the hood is raised. It can start anytime the ignition
switch is ON. You can be hurt by the fan.
• Do not attempt to push or tow your vehicle to get it
started. Unburned fuel could enter the catalytic con-
verter and once the engine has started, ignite and
damage the converter and vehicle. If the vehicle has
a discharged battery, booster cables may be used to
obtain a start from another vehicle. This type of start
can be dangerous if done improperly, so follow this
procedure carefully.
• Wear eye protection and remove any metal jewelry
such as watch bands or bracelets that might make an
inadvertent electrical contact. You could be seriously
injured.
256 WHAT TO DO IN EMERGENCIES

ONBOARD DIAGNOSTIC SYSTEM (OBD II)
To meet new government regulations and promote cleaner
air, your vehicle is equipped with a sophisticated onboard
diagnostic system called OBD II. This system monitors the
performance of the emissions and engine 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. It will also
store diagnostic codes and other information to assist your
service technician in making repairs. Although your ve-
hicle will usually be drivable and not need towing, see
your authorized dealer for service as soon as possible.
CAUTION!
Prolonged driving with the light 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 state emissions tests can
be performed.If the light is flashing, 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 con-
nect equipment to the OBD II connection port in
order to 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.

264 MAINTAINING YOUR VEHICLE

Exhaust System
The best protection against carbon monoxide entry into the
vehicle body is a properly maintained engine exhaust
system.
If you notice a change in the sound of the exhaust system;
or if the exhaust fumes can be detected inside the vehicle;
or when the underside or rear of the vehicle is damaged;
have an authorized technician inspect the complete ex-
haust system and adjacent body areas for broken, dam-
aged, deteriorated, or mispositioned parts. Open seams or
loose connections could permit exhaust fumes to seep into
the passenger compartment. In addition, have the exhaust
system inspected each time the vehicle is raised for lubri-
cation or oil change. Replace as required.
WARNING!
•Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can even-
tually poison you. To avoid breathing CO, refer to
“Safety Tips/Exhaust Gas” in “Things To Know Before
Starting Your Vehicle” for further information.
(Continued)
WARNING! (Continued)
•A hot exhaust system can start a fire if you park over
materials that can burn. Such materials might be
grass or leaves coming into contact with your exhaust
system. Do not park or operate your vehicle in areas
where your exhaust system can contact anything that
can burn.
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 involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.
274 MAINTAINING YOUR 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.Cooling System
WARNING!
• When working near the radiator cooling fan, discon-
nect the fan motor lead or cycle the ignition switch to
the LOCK position. The fan is temperature con-
trolled and can start at any time the ignition switch is
in the ON position.
• You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If
you see or hear steam coming from under the hood,
do not open the hood until the radiator has had time
to cool. Never try to open a cooling system pressure
cap when the radiator is hot.
Coolant Checks
Check engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where appli-
cable). If the engine coolant (antifreeze) is dirty, the system
should be drained, flushed, and refilled with fresh OAT
coolant (conforming to MS.90032) by an authorized dealer.
Check the front of the A/C condenser/radiator for any
accumulation of bugs, leaves, etc. If dirty, clean by gently
spraying water from a garden hose vertically down the face
of the condenser/radiator.
