Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something
is wrong before it becomes serious enough to cause an
expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there may be or is a
problem with one of the vehicle’s functions. Some
warning lights come on briey when the engine is
started to indicate they are working.
Gages can indicate when there may be or is a problem
with one of the vehicle’s functions. Often gages and
warning lights work together to indicate a problem with
the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there may
be a problem, check the section that explains what to do.
Follow this manual’s advice. Waiting to do repairs can be
costly and even dangerous.
