Tachometer
The tachometer displays the engine speed in revolutions
per minute (rpm).
If your engine speed equals or exceeds the safe limit for
operation, the message HOT...REDUCE ENG RPM is
displayed on the DIC.
NOTICE:
Do not operate the engine with the tachometer
in the shaded area, or when the message
HOT...REDUCE ENG RPM is displayed.
Engine damage may occur.
Warning Lights, Gages and Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
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
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they’re working. If you
are familiar with this section, you should not be alarmed
when this happens.
