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.Fuels in Foreign
Countries
If you plan on driving in another
country outside the United States or
Canada, the proper fuel might be
hard to nd. Never use leaded
gasoline or any other fuel not
recommended in the previous text
on fuel. Costly repairs caused
by use of improper fuel would not
be covered by the vehicle warranty.
To check the fuel availability, ask
an auto club, or contact a major oil
company that does business in
the country where you will be
driving.

Checking Things
Under the Hood
{CAUTION
An electric fan under the hood can
start up and injure you even when
the engine is not running. Keep
hands, clothing, and tools away
from any underhood electric fan.
{CAUTION
Things that burn can get on hot
engine parts and start a re.
These include liquids like fuel, oil,
coolant, brake uid, windshield
washer and other uids, and
plastic or rubber. You or others
could be burned. Be careful not to
drop or spill things that will burn
onto a hot engine.
Hood Release

Engine Oil
Checking Engine Oil
It is a good idea to check the
engine oil level at each fuel ll. In
order to get an accurate reading, the
oil must be warm and the vehicle
must be on level ground.The engine oil dipstick handle is a
yellow loop. SeeEngine
Compartment Overview on
page 5-10for the location of the
engine oil dipstick.
1. Turn off the engine and give the
oil several minutes to drain back
into the oil pan. If this is not
done, the oil dipstick might not
show the actual level.
2. Pull the dipstick and clean it with
a paper towel or cloth, then push
it back in all the way. Remove
it again, keeping the tip down and
check the level.

When to Add Engine Oil
If the oil is below the MIN (minimum)
mark, add at least one quart/liter
of the recommended oil. This
section explains what kind of oil to
use. For engine oil crankcase
capacity, seeCapacities and
Specifications on page 5-81.Notice:Do not add too much oil.
If the engine has so much oil
that the oil level gets above the
upper mark that shows the proper
operating range, the engine
could be damaged.
SeeEngine Compartment Overview
on page 5-10for the location of
the engine oil ll cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the
way back in when through.
What Kind of Engine Oil to Use
Look for three things:
5-12 Service and Appearance Care
ProCarManuals.com
GM6094M
Use only an oil that meets GM
Standard GM6094M.
SAE 5W-30
SAE 5W-30 is best for the
vehicle. These numbers on an oil
container show its viscosity, or
thickness. Do not use other
viscosity oils such as
SAE 20W-50.
American Petroleum Institute
(API) starburst symbol
Oils meeting these requirements
should have the starburst
symbol on the container. This
symbol indicates that the oil has
been certi ed by the American
Petroleum Institute (API).Notice:Use only engine oil
identi ed as meeting GM
Standard GM6094M and showing
the American Petroleum
Institute Certi ed For Gasoline
Engines starburst symbol. Failure
to use the recommended oil
can result in engine damage not
covered by the vehicle warranty.
Cold Temperature Operation
If in an area of extreme cold, where
the temperature falls below−20°F
(−29°C), use either an SAE 5W-30
synthetic oil or an SAE 0W-30
engine oil. Both provide easier cold
starting for the engine at extremely
low temperatures. Always use
an oil that meets the required
speci cation, GM6094M. See “What
Kind of Engine Oil to Use” for
more information.
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.
