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.
Gages can indicate when there may be or is a problem
with one of your vehicle's functions. Often gages and
warning lights work together to let you know when
there's a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it.
Please follow this manual's advice. Waiting to do repairs
--
can be costly and even dangerous. So please get to
know your warning lights and gages. They're a big help.

Low Coolant Warning Light

3500HD
Your vehicle has a LOW COOLANT light. As a check
to show you it's working, this light comes on for a few
seconds after the ignition is turned on.
If this light comes on anytime the engine is running,
your system is low on coolant and the engine may
overheat. See "Engine Coolant" in the Index.
Have your vehicle serviced as soon as you can.
