If
your
vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label),
it
is designed to operate on fuels that meet California
specifications.
If
such fuels are
not
available
in
states
adopting California emissions standards,
your
vehicle
will operate satisfactorily
on
fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may
turn
on and/or
your
vehicle
may fail a smog-check test.
If
this
occurs, return to your
authorized GM dealer for diagnosis
to
determine the
cause
of
failure.
In
the event
it
is
determined that the
cause
of
the condition is the type
of
fuels used, repairs
may not be covered by
your
warranty.
In
Canada. some gasolines contain an octane-enhancing
additive called
MMT.
If
you
use such fuels,
your
emission control system performance
may
deteriorate
and the tnalfunction indicator lamp
on
your
instrument
panel
may
turn
on.
If
this
happens,
return
to
your
authorized
CM
dealer for service.
To
provide cleaner air, all gasolines are
now
required
to
contain additives that
will
help prevent deposits from
forming
in
your
engine and fuel system, allowing your
emission control system
to
function properly. Therefore,
you
should
not
have to
add
anything
to
the
fuel.
In
addition, gasolines containing oxygenates, such
as
ethers
and ethanol, and reformulated gasolines may be
available
in
your area
to
help clean the air. General
Motors recommends that
you
use these gasolines
if
they
comply with the specifications described earlier.
NOTICE:
Your vehicle was
not
designed for fuel that
contains methanol. Don’t use it.
It
can corrode
metal parts
in
your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
