Before closing the hood, be sure all the filler
caps are on.
Then lift the hood to relieve pressure on the hood prop.
Remove the hood prop from the slot in the hood and
return the prop
to its retainer. Then let the hood down

it firmly.
Engine Oil
If the engine oil
pressure light on the
instrument panel comes
on, it means
you need
to check
your engine oil level
right away.
For more information,
see “Engine Oil Pressure Light”
in the Index. You should check your engine oil level
regularly; this is an added reminder. It’s a good
idea
to check your engine oil 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
drain back into the oil
pan. If you don’t, the oil
dipstick might not show
the actual level.

Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
iApBrh, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
When to Add Oil
If the oil is at or below the ADD mark, then you’ll need
to
add some oil. But you must use the right kind. This
part explains what kind of oil to use. For crankcase
capacity, see “Capacities
and Specifications” in the Index.
NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.
Just fill it enough to put the level somewhere in the
proper operating range. Push the dipstick all the way
back in when you’re through.

What Kind of Oil to Use
Oils recommended for your vehicle can be identified by
looking for the “Starburst” symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute (API).
Do not use any oil which
does not carry this Starburst symbol.
If you change your own
oil, be sure you use oil that
has the Starburst symbol on the front
of the oil
container. If you have
your
oil changed for you,
be sure the oil put into
your engine
is American
Petroleum Institute certified
for gasoline en~es.

You should also use the proper viscosity oil for your
vehicle, as shown
in the following chart:

As shown in the chart, SAE 5W-30 is best for your
vehicle. However, you can use SAE
1OW-30 if it’s going
to be 0°F (-1 8 “C) or above. These numbers on an oil
container
show its viscosity, or thickness. Do not use
other viscosity oils, such
as SAE 20W-50.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst”
symbol. Failure to use the
recommended oil can result in engine damage
not covered by your warranty.
GM Goodwrench@ oil meets all the requirements for
your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your Geo dealer is ready
to advise if
you think something should‘be added.
When to Change Engine Oil
See if any one of these is true for you:

Most trips are less than 5 to 10 miles (8 to 16 km).
This is particularly important when outside
temperatures are below freezing.
Most trips include extensive idling (such as frequent
driving in stop-and-go traffic).
You operate your vehicle in dusty areas or
off-road frequently.
You frequently tow a trailer or use a carrier on top of
your vehicle.
The vehicle is used for delivery service, police, taxi
or other commercial application.
Driving under these conditions causes engine
oil to
break down sooner.
If any one of these is true for your
vehicle, then you need to change your
oil and filter
every
3,000 miles (5 000 km) or 3 months -- whichever
occurs first.
If none of them is true, change oil and filter every
7,500 miles (12 500 km) or 7.5 months -- whichever
occurs first.
Driving a vehicle with a fully warned
engine under highway conditions causes engine oil to
break down slower.

What to Do with Used Oil
Did you know that used engine oil contains certain
elements that may be unhealthy for your skin and could
even cause cancer? Don’t 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 throw
away 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 real threat to the environment. If you
change your own oil, be sure to drain all free-flowing oil
from the filter before disposal. Don’t ever dispose
of oil
by putting it in the trash, pouring it on the ground, into
sewers, or into streams or bodies of water. Instead,
recycle
it by taking it to a place that collects used oil. If
you have a problem properly disposing of your used oil,
ask your dealer, a service station or a local recycling
center for help.
Air Cleaner
Refer to the Maintenance Schedule to determine when to
replace the air filter and the crankcase ventilation filter.
See “Scheduled Maintenance Services” in the Index.

~ Operating the
engine with the air cleaner off can
~ cause you or others to be burned. The air cleaner
~ not only cleans the air, it stops flame if the engine
backfires.
If it isn’t there, and the engine
backfires,
you could be burned. Don’t drive with
it
off, and be careful working on the engine with
the air cleaner off.
I NOTICE:
If the air cleaner is off, a backfire can cause a
damaging engine fire. And, dirt can easily get
into your
engine, which will damage it. Always
have the
air cleaner in place when you’re driving.
Air Filter Replacement

3. Pull out the filter.
Automatic Transmission Fluid
When to Check and Change
A good time to check your automatic transmission fluid
level is when the engine oil is changed.
Change both the fluid and filter every
50,000 miles
(83 000 km) if the vehicle is mainly driven under one or
more of these conditions:
0 In heavy city traffic where the outside temperature
regularly reaches
90°F (32” C) or higher.
In hilly or mountainous terrain.
When doing frequent trailer towing.
Uses such as found in taxi, police or delivery service.
If you do not use your vehicle under any of these
conditions, the fluid and filter do not
require changing.
See “Scheduled Maintenance Services” in the Index.
