called OBD II that monitors engine and auto-
matic 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 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
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
immediate loss of power or severe catalytic
converter damage. The vehicle should be ser-
viced as soon as possible if this occurs.
WARNING!
A malfunctioning catalytic converter, as refer-
enced 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, occu-
pants or others.
CAUTION!
Prolonged driving with the Malfunction Indi-
cator 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.

not be guaranteed.
Should one or more tires be in the condition
mentioned above, the display will show the
indications corresponding to each tire in se-
quence.
CAUTION!
Do not continue driving with one or more flat
tires as handling may be compromised. Stop
the vehicle, avoiding sharp braking and
steering. If a tire puncture occurs, repair
immediately using the dedicated tire repair kit
and contact your authorized dealer 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 plac-
