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 wl1e.n 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.

the cap. The diagnostic system can cleter~nine
if the fuel cap
has been left off
or improperly installed. A loose or
missing fuel cap
will allow fuel to evaporate into the

installed should turn
the light off,
Did you *just drive through a deep puddle of water’!

will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Have you recently changed brands of fuel?

the vehicle
into gear, mistlring, hesitation on acceleration
or
stumbling on acceleration. (These conditions may go
away once the engine is warmed up.) This will be detected
by the system and cause the light
to turn on.
If you experience one or more of these conditions,
change the fuel brand you use.
It will require at least one
full tank of the proper fuel to turn the light off.
If none of the above steps have made the light. turn off.
have your dealer or qualified service center check the
vehicle. Your dealer has the proper test equipment and
diagnostic
tools to fix any mechanical or electrical
problcnls that may have developed.
