If
the
Light
Is
Flashing
Are you
low
on
fuel?
The
following may prevent more serious
damage
to
your vehicle:
0
Reduce vehicle speed.
0
Avoid hard accelerations.
0
Avoid steep uphill grades.
If towing
a trailer, reduce the amount of cargo
being
hauled as
soon as
it
is possible.
If the light
stops
flashing and remains on steady, see
--IT
the Light
Is
On Steady”
following.
If the light continues to flash, when
it
is
safe to do
so,
stop
the
vehicle.
Put your vehicle in PARK (P). Turn the
key off, wait at least
10
seconds and restart the
engine.
If the light
remains on steady, see “If the Light
Is
On
Steady”
following. If the light is still flashing
follow the
previous
steps,
and
drive
the vehicle to your dealer
or
qualified
service
center
for
service.
If
the
Light
Is
On
Steady
You
may
be able
to
correct
the emission system
malfunction by considering
the
following:
Did
you
just drive through a
deep
puddle
of water?
If
so,
your electrical system may
be wet. The
condition
will usually be corrected when
the
electrical
system
dries
out.
A few driving trips should turn the light off.
As your engine starts
to
run out of
fuel,
your engine may
not
run
as
efficiently
as
designed since
small
amounts of
air
are
sucked
into
the
fuel
line causing
a misfire.
The
system
can
detect
this. Adding
fuel
should correct
this
condition. Make sure to install the fuel cap properly.
It
will take a
few
driving
trips
to
turn the light off.
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
this
condition,
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.
