DRIVING AND OPERATING 213
Caution
Do not use fuels with any of the
following conditions; doing so may
damage the vehicle and void its
warranty:. Fuel with any amount of
methanol, methylal, and
aniline. These fuels can
corrode metal fuel system
parts or damage plastic and
rubber parts.
. Fuel containing metals such
as methylcyclopentadienyl
manganese tricarbonyl
(MMT), which can damage
the emissions control system
and spark plugs.
. Fuel with a posted octane
rating of less than the
recommended fuel. Using this
fuel will lower fuel economy
and performance, and may
decrease the life of the
emissions catalyst.
Fuel Additives
Gasoline should contain detergent
additives that help prevent engine and
fuel system deposits from forming.
Clean fuel injectors and intake valves
will allow the emission control system
to work properly. Some gasoline does
not contain sufficient quantities of
additives to keep fuel injectors and
intake valves clean. To make up for
this lack of detergency, consult your
dealer for the GM approved additive
treatment. Add this additive to the
fuel tank at every engine oil change or
every 15 000 km (9,000 mi), whichever
occurs first.
Filling the Tank
{Warning
Fuel vapors and fuel fires burn
violently and can cause injury or
death.

Warning (Continued)
.To help avoid injuries to you
and others, read and follow
all the instructions on the
fuel pump island.
. Turn off the engine when
refueling.
. Keep sparks, flames, and
smoking materials away
from fuel.
. Do not leave the fuel pump
unattended.
. Do not use a cell phone while
refueling.
. Do not reenter the vehicle
while pumping fuel.
. Keep children away from the
fuel pump and never let
children pump fuel.
. Fuel can spray out if the
refueling nozzle is inserted
too quickly. This spray can
happen if the tank is nearly
full, and is more likely in hot

294 SERVICE AND MAINTENANCE
‐Any vehicle consistently
operated in a high sand or dust
environment such as those used
on oil pipelines and similar
applications.
. Vehicles that are regularly used for
short trips of 6 kilometers or less
If your vehicle has an Oil Life
Indicator, the indicator will show
you when to change the oil and
filter. Under severe conditions the
indicator may come on before
10 000 km/6,000 mi. The indicator
won't detect dust in the oil, so if
you drive in a dusty area you may
have to change the oil and filter
sooner than every 10 000 km/
6,000 mi. Note: All vehicles with rear-wheel
drive
—change driveline axle oil
every 30 000 km/19,000 mi if
vehicle is used for towing
purposes.
* Footnote: Under extreme driving
conditions listed above, it may be
necessary to replace your spark
plugs at more frequent intervals.
For further assistance in
determining the most suitable
service maintenance intervals for
your vehicle, please contact your
authorized GM Dealer.
