contain additives that will help prevent deposits from
forming in your engine and fuel system, allowing your
emission control system
to function properly. Therefore,
you should not have
to add anything to the fuel. In
addition, gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines may be
available in your area to help clean the air. General
Motors recommends that
you use these gasolines if they
comply with
the specifications described earlier.
NOTICE:
~~~ ~
Your vehicle was not designed for fuel that
contains methanol. Don’t use it.
It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada,
the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended
in the previous text on fuel. Costly repairs
caused by use of improper
fuel 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

To open the hood, first pull
the handle inside the vehicle
on the lower driver's side of
the instrument panel.
Then go to the front of the vehicle and release the
secondary hood release. Lift the hood, release
the hood
prop from its retainer and
put the hood prop into the slot
in the hood. You may

Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, 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.

Downloaded from www.Manualslib.com manuals search engine Before closing the hood, be sure all the filler caps are on
properly. 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 just pull the hood down firmly
to close. It will
latch when dropped from
10 to12 inches (25 to 30 cm)
without pressing
on the hood.
Engine Oil
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.
The oil dipstick is
a
yellow ring.
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.
Checking 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 down, and check the level.
When to Add Oil
If the oil is at or below the ADD line, 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.

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:
In heavy city traffic where the outside temperature
regularly reaches
90°F (32°C) or higher.
0 In hilly or mountainous terrain.
When doing frequent trailer towing.
0 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.
How to Check
Because this operation can be a little difficult, you
may choose to have this done at your GM dealer
Service Department.
If you do it yourself, be sure to follow all the instructions
here, or you could get
a false reading on the dipstick.
I NOTICE:
Too much or too little fluid can damage your
transmission.
Too much can mean that some of
the fluid could come out and fall on hot engine
parts or exhaust system parts, starting a fire. Be
sure to get an accurate reading if you check your
transmission fluid.
Wait at least 30 minutes before checking the
transmission fluid level
if you have been driving:
When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
In heavy traffic -- especially in hot weather.
While pulling a trailer.
To get the right reading, the fluid should be at normal
operating temperature, which is
180°F to 200°F
(82°C to 93°C).

Get the vehicle warmed up by driving about 15 miles
(24 km) when outside temperatures are above 50°F
(10°C). If it's colder than 50°F ( 10°C), drive the
vehicle in
DRIVE (D) until the engine temperature gage
moves and
then remains steady for 10 minutes. Then
follow the
hot check procedures.
Checking Transmission Fluid Cold
A cold check is made after the vehicle has been sitting
for eight hours or more with the engine
off and is used
only as a reference. Let the engine run at idle for five
minutes if outside temperatures are
50°F (10°C) or
more. If it's colder than 50°F (lO"C), you may have to
idle the engine longer. Should
the fluid level be low
during a cold check, you
must perform a hot check
before adding fluid. This will give you
a more accurate
reading
of the fluid level.

then
pull it back out again,
3. Check both sides of the dipstick, and read the lower
level. The fluid level must be in the COLD area for a
cold check or in the HOT area or cross-hatched area
for a hot check.
4. If the fluid level is in the acceptable range, push the
dipstick back in all
the way; then flip the handle
down
to lock the dipstick in place.
How to Add Fluid
Refer to the Maintenance Schedule to determine what
kind
of transmission fluid to use. See “Recommended
Fluids and Lubricants”
in the Index.
Add fluid only after checking the transmission fluid
HOT. (A COLD check is used only as
a reference.) If
the fluid level is low, add only enough
of the proper
fluid to bring the level up
to the HOT area for a hot
check. It doesn’t take much fluid, generally less than a
pint. Don ’t overfill. We recommend you use only fluid
labeled DEXR0N’-111, because fluid with that label is
made especially
for your automatic transmission.
Damage caused by fluid other than DEXRON@-I11 is
not covered by your new vehicle warranty.
After adding fluid, recheck the fluid level as
described under “How to Check.”
When the correct fluid level is obtained, push the
dipstick back in all the way; then flip the handle
down to lock the dipstick in place.

cool enough for you to rest your fingers on the
transmission case.
Then, follow these steps:
1. Remove the filler plug.
2. Check that the lubricant level is up to the bottom of
the filler plug hole.
3. , If the fluid level is good, install the plug and be sure
it is fully seated. If the fluid level is low, add more
fluid as described in

you’ll need to
add some lubricant. Add enough lubricant
to raise the level to the bottom of the filler plug hole.
