Have
you
recently changed brands
of
fuel?
If
so,
be sure to fuel your vehicle with quality fuel
(see
“Fuel”
in the Index). Poor fuel quality will cause your
engine not to run as efficiently as designed. You may
notice this as stalling after start-up, stalling when
you
put the vehicle into gear, misfiring, 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
problems that may have developed.
Oil Warning Light
If you have a problem with
your oil, this light may stay
on
after
you
start your
engine, or come on when
you are driving.
This indicates that oil is not going through your engine
quickly enough
to
keep it lubricated. The engine could
be low on oil or could have some other oil problem.
Have it fixed right away.
The oil light could also come on in the
following situations:
The light will come
on
briefly when you turn on the
ignition to show
you
that it is working properly. (If it
doesn’t come
on
with the ignition on, you may have
a problem with the fuse or bulb. Have it fixed
right away.)
Sometimes when the engine is idling at
a
stop, the
light may blink on and off. This is normal.
