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.
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.
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.

Downloaded from www.Manualslib.com manuals search engine When to Add Oil
If the oil is at or below the ADD line. then you'll need
to add at least one quart of 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
cross-hatched area that shows the proper
operating range, your engine could be damaged.
Be sure to 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
Petroleunl 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 engines.
You should
also use the proper viscosity oil for your
vehicle. as
shown in the following chart:

LOOK

SYMBOL
DO NOT USE SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED
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.
I 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.
If you are in an area where the temperature falls below
-20°F (-29OC), consider using either an SAE 5W-30
synthetic oil or an SAE OW-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.

Don't add anything to your oil. Your GM dealer is ready
to advise if you think something should be added.
When to Change Engine Oil
If any one of these is true for you. use the short tripkity
. maintenance schedule:
a
a
a
0
a
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 currier 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
occllrs first.
If none of them is true, use the long trip/highway
maintenance schedule. Change the oil and filter every
7,500 miles ( 12 500 km) or 12 months -- whichever
occurs first. Driving
a vehicle with a fully warmed
engine under highway conditions causes engine oil
to
break down slower.
Remote Oil Filter (Four-wheel Drive)
The access door for the remote oil filter is in the steering
linkage shield assembly located under the radiator
support.
Twist the screw to unlock or lock the door.
Make sure
if you open the door. it is securely closed
when
~OLI are finished.

Downloaded from www.Manualslib.com manuals search engine 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
cr
To remove the air cleaner, remove the wing nuts that
hold
the cover on. Remove the cover and lift out the
air filter.
Insert
a new air filter, then replace the air cleaner cover.
Tighten the wing
nuts to hold the cover in place.

Downloaded from www.Manualslib.com manuals search engine A CAUTION:
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.
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.
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
(53 000 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.
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.

When to Check
A good time to have it checked is when the engine oil is
changed. However, the fluid in your manual
transmission doesn't require changing.
How to Check
Because this operation can be a little difficult. you
rnay choose to have this done at your GM dealership
Service Department.
If you do it yourself. be sure to follow all the
instructions here, or
you could get a false reading.
I NOTICE:
i Too much or too little fluid can damage your
1 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.
Check the fluid level only when your engine is off, the
vehicle
is parked on a level place and the transmission is
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 LIP to the bottom of
the filler plug hole.
3. If the fluid level is good. install the pl~~g md be sure
it is f~llly seated. If the fluid level is low. add more
fluid as described in the next steps.
