For customers who do not use TOP
TIER Detergent Gasoline regularly,
one bottle of GM Fuel System
Treatment PLUS, added to the fuel
tank at every engine oil change,
can help clean deposits from fuel
injectors and intake valves. GM Fuel
System Treatment PLUS is the only
gasoline additive recommended by
General Motors.
Also, your dealer/retailer has
additives that will help correct and
prevent most deposit-related
problems.
Gasolines containing oxygenates,
such as ethers and ethanol, and
reformulated gasolines might
be available in your area. We
recommend that you use these
gasolines, if they comply with the
speci cations described earlier.However, E85 (85% ethanol) and
other fuels containing more than
10% ethanol must not be used in
vehicles that were not designed for
those fuels.
Notice:This vehicle was not
designed for fuel that contains
methanol. Do not use fuel
containing methanol. It can
corrode metal parts in the fuel
system and also damage plastic
and rubber parts. That damage
would not be covered under
the vehicle warranty.
Some gasolines that are
not reformulated for low
emissions can contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT); ask the
attendant where you buy gasoline
whether the fuel contains MMT.We recommend against the use of
such gasolines. Fuels containing
MMT can reduce the life of spark
plugs and the performance of the
emission control system could be
affected. The malfunction indicator
lamp might turn on. If this occurs,
return to your dealer/retailer for
service.

Engine Oil Additives / Engine
Oil Flushes
Do not add anything to the oil.
The recommended oils with the
starburst symbol that meet GM
Standard GM6094M are all that is
needed for good performance and
engine protection.
Engine oil system ushes are not
recommended and could cause
engine damage not covered by the
vehicle warranty.
Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and lter. This is based
on engine revolutions and engine
temperature, and not on mileage.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably. For
the oil life system to work properly,
the system must be reset every time
the oil is changed.When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A change engine oil light
comes on. SeeChange Engine Oil
Light on page 3-38. Change the oil
as soon as possible within the next
600 miles (1 000 km). It is possible
that, if driving under the best
conditions, the oil life system might
not indicate that an oil change is
necessary for over a year. However,
the engine oil and lter must be
changed at least once a year and at
this time the system must be reset.
Your dealer/retailer has trained
service people who will perform this
work using genuine parts and reset
the system. It is also important to
check the oil regularly and keep it at
the proper level.
If the system is ever reset
accidentally, the oil must be
changed at 3,000 miles (5 000 km)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
The Engine Oil Life System
calculates when to change the
engine oil and lter based on vehicle
use. Whenever the oil is changed,
reset the system so it can calculate
when the next oil change is required.
If a situation occurs where the oil is
changed prior to a change engine
oil light being turned on, reset the
system.
After changing the engine oil, reset
the system:
1. Turn the ignition key to ON/RUN
with the engine off.
2. Fully press and release the
accelerator pedal three times
within ve seconds.
If the change engine oil light is
not on, the system is reset.
If the light comes on again and stays
on for 30 seconds at the next ignition
cycle, it did not reset. The system
needs to be reset again.

What to Do with Used Oil
Used engine oil contains certain
elements that can be unhealthy for
your skin and could even cause
cancer. Do not let used oil stay on
your skin for very long. Clean your
skin and nails with soap and water,
or a good hand cleaner. Wash or
properly dispose of clothing or rags
containing used engine oil. See the
manufacturer’s warnings about the
use and disposal of oil products.
Used oil can be a threat to the
environment. If you change your own
oil, be sure to drain all the oil from the
lter before disposal. Never dispose
of oil by putting it in the trash, pouring
it on the ground, into sewers, or into
streams or bodies of water. Recycle
it by taking it to a place that collects
used oil.
Engine Air Cleaner/Filter
SeeEngine Compartment Overview
on page 5-12for the location of the
engine air cleaner/ lter.
When to Inspect the Engine
Air Cleaner/Filter
Inspect the air cleaner/ lter at the
MaintenanceIIintervals and replace
it at the rst oil change after each
50,000 mile (80 000 km) interval.
SeeScheduled Maintenance on
page 6-3for more information. If you
are driving in dusty/dirty conditions,
inspect the lter at each engine oil
change.
How to Inspect the Engine Air
Cleaner/Filter
To inspect the air cleaner/ lter
remove the lter from the vehicle
and lightly shake the lter to release
loose dust and dirt. If the lter
remains caked with dirt, a new lter
is required.To inspect or replace the engine air
cleaner/ lter, do the following:
1. Remove the clamp on the air
duct hose.
2. Disconnect the hose.
3. Remove the four bolts on the
side of the air cleaner assembly.
4. Turn the cover upward to
disengage the cover hinges.
5. Remove the air cleaner cover
assembly and air lter element.

Requirements
Notice:Maintenance intervals,
checks, inspections, replacement
parts, and recommended uids
and lubricants as prescribed
in this manual are necessary to
keep this vehicle in good working
condition. Any damage caused
by failure to follow scheduled
maintenance might not be

Your Vehicle and the
Environment
Proper vehicle maintenance not only
helps to keep the vehicle in good
working condition, but also helps the
environment. All recommended
maintenance is important. Improper
vehicle maintenance can even
affect the quality of the air we
breathe. Improper uid levels or the
wrong tire in ation can increase
the level of emissions from the
vehicle. To help protect the
environment, and to keep the
vehicle in good condition, be sure to
maintain the vehicle properly.
