Engine Check/Malfunction Indicator Light (MIL)
Yellow Telltale
Light 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.204 UNDERSTANDING YOUR INSTRUMENT PANEL

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. 4UNDERSTANDING YOUR INSTRUMENT PANEL 205

Tire Pressure Monitoring Indicator Light
Yellow Telltale
Light What It Means
Tire Pressure Monitoring Indicator Light
The warning light switches on and a message is displayed to indicate that the tire pressure is
lower than the recommended value and/or that slow pressure loss is occurring. In these cases,
optimal tire duration and fuel consumption may not be guaranteed.
Should one or more tires be in the condition mentioned above, the display will show the indica-
tions corresponding to each tire in sequence.
CAUTION!Do not continue driving with one or more flat tires as
handling may be compromised. Stop the vehicle,
avoiding sharp braking and steering. Repair immedi-
ately using the dedicated tire repair kit and contact
your authorized dealership as soon as possible.
Each tire, including the spare (if provided), should be
checked monthly when cold and inflated to the inflation
pressure recommended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure label. If your
vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label, you
should determine the proper tire inflation pressure for
those tires.
As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System (TPMS)
that illuminates a low tire pressure telltale when one or
more of your tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible and
inflate them to the proper pressure. Driving on a signifi-
cantly under-inflated tire causes the tire to overheat and
can lead to tire failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may affect the vehicle’s
handling and stopping ability.208 UNDERSTANDING YOUR INSTRUMENT PANEL

Low Fuel Indicator Light

Low Fuel Indicator Light
When the fuel level reaches approximately 3.0 gal (11.0 L) this light will turn on, and remain on
until fuel is added.
Anti-Lock Brake (ABS) Indicator Light
Yellow Telltale
Light What It Means
Anti-Lock Brake (ABS) Indicator Light
After the ignition is turned on, the Anti-Lock Brake System (ABS) light illuminates to indicate
function check at vehicle startup. If the light remains on after startup or comes on and stays on at
road speeds, it may indicate that the ABS has detected a malfunction or has become inoperative.
The system reverts to standard non-anti-lock brakes.
If both the Brake Warning Light and the ABS Warning Light are on, see an authorized dealer im-
mediately. Refer to “Anti-Lock Brake System” in “Starting And Operating” for further informa-
tion.210 UNDERSTANDING YOUR INSTRUMENT PANEL
