r
Fuel
Use regular unleaded gasoline rated at
87 octane or higher. It should meet
specifications, ASTM
D4814 in the U.S.
and CGSB 3.5-M92 in Canada. These
fuels should have the proper additives,
so you should not have to add anything
to the fuel.
In the U.S. and Canada, it’s easy to be
sure you get the right kind of gasoline
(unleaded). You’ll see
UNLEADED
right on the pump. And only unleaded
nozzles will fit into your vehicle’s filler
neck.
Be sure the posted octane is at least
87.
If the octane is less than 87, you may
get a heavy knocking noise when you drive.
If it’s bad enough, it can damage
your engine.
If you’re using fuel rated at
87 octane or
higher and you still hear heavy
knocking, your engine needs service.
But don’t worry if you hear a little
pinging noise when you’re accelerating or driving up a
hill. That’s normal, and
you don’t have to buy a higher octane
fuel to get rid of pinging. It’s the heavy,
constant knock that means you have a
problem.
What about gasoline with blending materials that contain oxygen, such as
MTBE or alcohol?

Gasolines for Cleaner Air
Your use of gasoline with detergent
additives will help prevent deposits from
forming in your engine and fuel system.
That helps keep your engine in tune and your emission control system working
properly. It’s
good for your vehicle, and
you’ll be doing your part for cleaner air.
Many gasolines are now blended with
materials called oxygenates. General
Motors recommends that you use
gasolines
with these blending materials,
such as MTBE and ethanol.
By doing
so, you can help clean the air, especially
in those parts of the country that have
high carbon monoxide levels.

In addition, some gasoline suppliers are
now producing reformulated gasolines.
These gasolines are specially designed to
reduce vehicle emissions. General
Motors recommends that you use
reformulated gasoline. By doing
so, you
can help clean the air, especially in
those parts of the country that have high
ozone levels,
You should ask your service station
operators
if their gasolines contain
detergents and oxygenates, and if they
have been reformulated
to reduce
vehicle emissions.
Fuels in Foreign Countries
If you plan on driving in another
country outside the
U.S. or Canada,
unleaded fuel may be hard to find.
Do
not use leaded gasoline. If you use even
one tankful, your emission controls
won’t work well or at
all. With
continuous use, spark plugs can get
fouled, the exhaust system can corrode,
and your engine oil
can deteriorate
quickly. Your vehicle’s oxygen sensor
will be damaged. All of that means costly repairs that wouldn’t be covered
by your warranty.
To check on fuel availability, ask an
auto club, or contact a major oil company that does business in
the
country where you’ll be
driving.
You can also write us at the following
address for advice. Just tell us where
you’re going and give your Vehicle
Identification Number
(VIN).

from the slot in the hood and return the
prop to its retainer. Then just let the
hood down and close it firmly.
Engine Oil
It’s a good idea to check your engine oil
level every time you get fuel.
In order
to get an accurate reading, the oil must
be warm and the vehicle must be on
level ground.
Turn
off the engine and give the oil a
few minutes to drain back into the oil
pan.
If you don’t, the oil dipstick might
not show the actual level.
To Check Engine Oil: Pull out 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
lower.

Loading Your Vehicle
Two labels on your vehicle show how
much weight
it may properly carry. The
Tire-Loading Information label found on
the driver’s door lock pillar tells you the
proper size, speed rating and
recommended inflation pressures for the
tires on your vehicle. It also gives you
important information about the number
of people that can be in your vehicle and
the total weight that you can carry. This
weight is called the Vehicle Capacity
Weight and includes the weight of all
occupants, cargo, and all
nonfactory-installed options. The other
label is the Certification label,
11
found on the rear edge of the driver’s
door. It tells you the gross weight
capacity of your vehicle, called the
GVWR (Gross Vehicle Weight Rating).
The GVWR includes the weight of the
vehicle, all occupants, fuel and cargo.
Never exceed the GVWR for your
vehicle, or the Gross Axle Weight
Rating (GAWR) for either the front or
rear axle.
And, if you do have a heavy load, you
should spread it out. Don’t carry more
than
900 pounds (408 kilograms) in your
rear area.
1
CAUTION
Do not load your vehicle any
heavier than the GVWR or
the
maximum front and rear I
GAWRs. If you do, parts on you]
vehicle can break, or it can chang
the way your vehicle handles.
These could cause you to lose
control. Also, overloading can
shorten the life of your vehicle.

Service & Appearance Care
Finish Damage
Any stone chips, fractures or deep
scratches in the finish should be repaired
right away. Bare metal will corrode
quickly and may develop into a major
repair expense.
Minor chips and scratches can be
repaired with touch-up materials
available from your dealer or other
service outlets. Larger areas of finish
damage can be corrected in your
dealer’s body and paint shop.
Underbody Maintenance
Chemicals used for ice and snow
removal and dust control can collect on
the underbody. If these are not removed,
accelerated corrosion (rust) can occur on
the underbody parts such as fuel lines,
frame, floor pan, and exhaust system
even though they have corrosion
protection.
At least every spring, flush these
materials from the underbody
with plain
water. Clean any areas where mud and
other debris can collect. Dirt packed in
closed areas of the frame should be
loosened before being flushed. Your
dealer or an underbody vehicle washing
system can do this for you.
Chemical Paint Spotting
Some weather and atmospheric
conditions can create a chemical fallout.
Airborne pollutants can
fall upon and
attack painted surfaces on your vehicle. This damage can take two forms:
blotchy, ringlet-shaped discolorations,
and small irregular dark spots etched
into the paint surface.
Although no defect in the paint job
causes this, Geo will repair, at no
charge to the owner, the surfaces of new
vehicles damaged by this fallout
condition within
12 months or 12,000
miles (20 OOO km) of purchase,
whichever comes first.
