If your vehicle is certified to meet California Emission Standards (indicated on the underhood emission control label), it is designed to operateon fuels that meet California specifications. If such fuels are not available in statesadopting California emissionsstandards, 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 Aurora retailer for diagnosis to determine the cause of failure. Inthe event it is determined that the cause of the condition is the type of fuels used, repairs may not becovered by your warranty. Some gasolines that arenot reformulated for low emissions contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask your service station operator whether or not his fuel contains MMT. General Motors does not recommend the use of such gasolines. If fuels containingMMT are used, spark plug life may be reduced and your emission control system performance may be affected. The malfunction indicator lamp on your instrument panel may turn on. If this occurs, return to your authorized Aurora retailer for service. To provide cleaner air, all gasolines in the United States 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 ethersand 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. I NOTICE: Your vehicle was not designed fuel that for contains methanol. Don't use It can corrode it. metal parts in your fuel system and also damage plastic and rubber parts. That damage wouldn't be covered under your warranty. 6-4

If your vehicle is certified to meet California Emission
Standards (indicated on the underhood emission control
label), it is designed to
operate
on
fuels that meet
California specifications.
If
such fuels
are
not available
in
statesadopting 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 Aurora retailer 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.
Some gasolines that
are not reformulated for low
emissions contain an octane-enhancing additive
called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask your service station operator whether or not his fuel
contains MMT. General Motors does not recommend the
use of such gasolines.
If
fuels
containing MMT are used,
spark plug life may be reduced and your emission
control system performance may
be
affected. The
malfunction indicator lamp on your instrument panel
may turn on.
If
this occurs, return to your authorized
Aurora retailer for service.
To provide cleaner air, all gasolines in the United States
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.
I
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.
