Fuel Gage
Your fuel gage tells you about how
much fuel you have left, when
the ignition is on.
When the indicator nears empty,
the low fuel warning light will come
on. You still have a little fuel left,
but you should get more soon.
SeeLow Fuel Warning Light
on page 4-24for more information.
The arrow on the fuel gage points
to the side of the vehicle with
the fuel door.Here are ve things that some
owners ask about. These are normal
and do not indicate a problem
with your fuel gage:
At the service station, the gas
pump shuts off before the
gage reads full.
It takes a little more or less fuel
to ll up than the gage indicated.
The indicator moves a little when
you turn a corner or speed up.
The gage goes back to empty
when you turn off the ignition.
The vehicle is driven or parked
on a grade.
Low Fuel Warning Light
This light, below the fuel gage,
should come on briey when the
ignition is turned on as a check to let
you know that the light is working.
This light also comes on when
the fuel tank is low on fuel. When
you add fuel the light should go off.
If it does not, have your vehicle
serviced.

Fuel
Use of the recommended fuel
is an important part of the proper
maintenance of this vehicle. To help
keep the engine clean and maintain
optimum vehicle performance, we
recommend the use of gasoline
advertised as TOP TIER Detergent
Gasoline.
Gasoline Octane
Use regular unleaded gasoline with a
posted octane rating of 87 or higher.
If the octane rating is less than 87,
you might notice an audible knocking
noise when you drive, commonly
referred to as spark knock. If this
occurs, use a gasoline rated at
87 octane or higher as soon as
possible. If you are using gasoline
rated at 87 octane or higher and you
hear heavy knocking, the engine
needs service.
Gasoline Specications
At a minimum, gasoline should
meet ASTM specication D 4814
in the United States or
CAN/CGSB-3.5 or 3.511 in Canada.
Some gasolines contain an
octane-enhancing additive called
methylcyclopentadienyl manganese
tricarbonyl (MMT). We recommend
against the use of gasolines
containing MMT. SeeAdditives on
page 8-34for additional information.
California Fuel
If the vehicle is certied to meet
California Emissions Standards, it is
designed to operate on fuels that
meet California specications. See
the underhood emission control
label. If this fuel is not available in
states adopting California emissions
standards, the vehicle will operate
satisfactorily on fuels meeting federal
specications, but emission control
system performance might be
affected. The malfunction indicator
lamp could turn on and the vehiclemight fail a smog-check test. See
Malfunction Indicator Lamp on
page 4-18. If this occurs, return to
your authorized dealer/retailer for
diagnosis. If it is determined that the
condition is caused by the type of
fuel used, repairs might not be
covered by the vehicle warranty.
Additives
To provide cleaner air, all gasolines
in the United States are now
required to contain additives that
help prevent engine and fuel system
deposits from forming, allowing
the emission control system to work
properly. In most cases, you
should not have to add anything to
the fuel. However, some gasolines
contain only the minimum amount of
additive required to meet U.S.
Environmental Protection Agency
regulations. To help keep fuel
injectors and intake valves clean, or
if the vehicle experiences problems
due to dirty injectors or valves,
look for gasoline that is advertised
as TOP TIER Detergent Gasoline.
8-34 Driving and Operating
ProCarManuals.com

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
specications 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.

What to Add
Use only new DOT-4 brake uid
from a sealed container. It is
recommended that the brake
hydraulic system be ushed and
relled with new DOT-4 uid
at a regular maintenance service
every two years. SeeAdditional
Required Services on page 11-6
andRecommended Fluids and
Lubricants on page 11-12.
Always clean the brake uid
reservoir cap and the area around
the cap before removing it.
This helps keep dirt from entering
the reservoir.
{CAUTION
With the wrong kind of uid in
the brake hydraulic system,
the brakes might not work well.
This could cause a crash.
Always use the proper brake uid.Notice:
Using the wrong uid can badly
damage brake hydraulic system
parts. For example, just a few
drops of mineral-based oil,
such as engine oil, in the brake
hydraulic system can damage
brake hydraulic system parts so
badly that they will have to be
replaced. Do not let someone
put in the wrong kind of uid.
If brake uid is spilled on the
vehicle’s painted surfaces, the
paint nish can be damaged.
Be careful not to spill brake
uid on the vehicle. If you do,
wash it off immediately. See
Exterior Cleaning on page 9-76.
Brake Wear
This vehicle has disc brakes.
Notice:Continuing to drive
with worn-out brake pads could
result in costly brake repair.
Front disc brake pads have built-in
brake pad wear indicators that
make a high-pitched warning sound
when the brake pads are worn
and new pads are needed.
The sound can come and go or be
heard all the time the vehicle is
moving, except when applying the
brake pedal rmly.
{CAUTION
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
an accident. When the brake wear
warning sound is heard, have the
vehicle serviced.
Vehicle Service and Care 9-23

Rear disc brake pads do not have
built-in brake pad wear indicators.
Periodic visual inspection of the rear
brake pads is required to determine
when to replace the pads. Visually
inspect the rear brake pads
whenever the rear wheels are
removed such as during tire rotation.
1. Set the parking brake and make
sure that the brakes have been
given enough time to cool.
2. Remove the rear wheels.
3. Visually inspect the rear brake
inner pads (C) at each rear
wheel through the inspection
window in the brake caliper (A).Brake pads should be replaced
when the inner pad (C) is
worn to 5/64 in (2 mm) of pad
thickness (B). New brake pads,
with no wear, are 25/64 of
an inch (10 mm) thick.
4. After brake pad inspection or
replacement, install the rear
wheels.
Some driving conditions or climates
can cause a brake squeal when
the brakes are rst applied or
lightly applied. This does not mean
something is wrong with the brakes.Properly torqued wheel bolts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear
and evenly tighten wheel bolts in
the proper sequence to torque
specications inCapacities
and Specifications on page 10-2.
Brake linings should always
be replaced as complete axle sets.
Brake Pedal Travel
See your dealer/retailer if the brake
pedal does not return to normal
height, or if there is a rapid increase
in pedal travel. This could be a
sign that brake service might
be required.
Brake Adjustment
Every brake stop, the disc brakes
adjust for wear.
