9. Malfunction Indicator Light
This light is part of an onboard diagnostic system
called OBD that monitors emissions, engine, and
automatic transmission control systems. The light
will illuminate when the key 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 condi-
tion checked promptly.
Certain conditions such as a loose or missing gas cap,
poor fuel quality, etc. may illuminate the light 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.
If the Malfunction Indicator Light flashes when the
engine is running, serious conditions may exist that
could lead to immediate loss of power or severe catalytic
converter damage. The vehicle should be serviced as
soon as possible if this occurs. (See page 360 for more
10. Turn Signal Indicators
The arrows will flash in unison with the exterior
turn signal, when using the turn signal lever.
NOTE: Turn signal bulbs are located in the Instrument
Panel. (See page 181 for more information.)
11. Electronic Stability Program (ESP) Indicator
Light/Traction Control System (TCS) Indicator Light
If Equipped
If this indicator light flashes during accelera-
tion, apply as little throttle as possible. While
driving, ease up on the accelerator. Adapt your
speed and driving to the prevailing road con-
ditions, and do not switch off the ESP, or TCS if
equipped. (See page 298 for more information.)
