on each vehicle. Put an automatic transmission in PARK (P) or a
manual transmission in NEUTRAL
(N). If you have a
four-wheel-drive vehicle with a manual transfer case shift lever, be
sure the transfer case
is not in NEUTRAL (N).
3. Turn off the ignition on both vehicles. Turn off all lights that aren’t
needed, and radios. This will avoid sparks and help save both batteries
And it could save your radio!
NOTICE:
If you leave your radio on, it could be badly damaged. The
repair wouldn’t be covered by your warranty.
~~
4. Open both hoods and locate the batteries. Find the positive (+) and
negative
(-) terminals on each battery.
5. Check that the jumper cables don’t have loose or missing insulation. If
they do, you could get a shock. The vehicles could be damaged too.
Before you connect the cables, here are some basic things you should
know. Positive (+) will go to positive (+) and negative (-) will go to
negative
(-) or a metal engine part. Don’t connect (+) to (-) or you’ll
get a
short that would damage the battery and maybe other parts too.

Downloaded from www.Manualslib.com manuals search engine Gasolines for Cleaner Air
Your use of gasoline with deposit control additives will help preven\
t
deposits from forming in your engine and fuel system. That hel\
ps 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 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
deposit control additives 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 (VI\
N).

NOTICE:
If you need a new cap, be sure to get the right type. Your dea\

might be damaged.
Checking Things Under the Hood

Remove the hood prop
from the slot in the
hood and return the
I
prop to its retainer.
Then just pull the hood down firmly to close.
It will latch when dropped
from 10
- 12 inches (25.5 - 30.48 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.
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 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 down.
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.\

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 pro\
per
operating range, your engine could be damaged.
The engine oil filler cap is located on the driver’s side engine valve cover.
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. \

Downloaded from www.Manualslib.com manuals search engine While reassembling the air cleaner assembly, ensure that the air cleaner
cover tabs are fully inserted into the slots in the air cleaner housing. On the
4.3L (VIN W) engine, also make certain that the PCV air tube is properly
seated in the left hand valve cover.
Refer to the Maintenance Schedule to determine
when to redace the air
filter.
See “Scheduled Maintenance Services” in the Index.
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 d\
amage
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. Refer to the Maintenance Schedule to determine
when to change your fluid. 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 dealership 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.

Downloaded from www.Manualslib.com manuals search engine 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 flui\
d.
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.
0 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).
To check transmissionfluid hot: 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 ( lO"C), drive the vehicle in THIRD GEAR (D) until
the engine temperature gage moves and then remains steady for ten minutes.
Then follow the hot check procedures.
To check transmissionfluid cold: A cold check is rnaae 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.
To check the fluid hot or cold
Park your vehicle on a level place. Keep the engine running.
0 With the parking brake applied, place the shift lever in Park (P).
With your foot on the brake pedal, move the shift lever through each
gear range, pausing
for about three seconds in each range. Then,
position the shift lever in Park (P).
Let the engine run at idle for three minutes or more.
