21. Vehicle Security Light
If during starting, the key code is not correctly
recognized, the Vehicle Security Light comes
on in the instrument panel. In this case, turn
the key to OFF and then to ON/RUN; if it is
still locked, try again with the other keys that come with
the vehicle. Contact an authorized studio if you still
cannot start the engine.
If with the engine running the warning light flashes, this
means that the car is not protected by the engine inhibitor
device. Contact an authorized studio to have all the keys
programmed.
22. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system, called OBDII, that
monitors engine and Euro Twin Clutch Transmis-
sion control systems. The light will illuminate when the
key is in the ON/RUN position before engine start. If the
UNDERSTANDING YOUR INSTRUMENT PANEL 165
bulb does not come on when turning the key from
OFF/LOCK to ON/RUN, have the condition checked
promptly.
Certain conditions, such as poor fuel quality, etc., may
illuminate the MIL after engine start. The vehicle should
be serviced if the light stays on through several of your
typical driving cycles. In most situations, the vehicle will
drive normally and will not require towing.
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.
