When You Are Ready to Leave After Parking on a Hill
1. Apply your regular brakes and hold the pedal down while you:
Start your engine;
Shift into a gear; and
Release the parking brake.
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
Maintenance When Trailer Towing
Your vehicle will need service more often when you’re pulling a trailer. See
the Maintenance Schedule for more on this. Things that are especially
important in trailer operation are automatic transmission fluid (don’t
overfill), engine oil, axle lubricant, belt, cooling system, an\
d brake
adjustment. Each
of these is covered in this manual, and the Index will help
you find them quickly.
If you’re trailering, it’s a good idea to review these
sections before you
start your trip.
Check periodically to see that all hitch nuts and bolts are tight.

To Jump Start Your Vehicle:
1. Check the other vehicle. It must have a 12-volt battery wlm a\
negauve
ground system.
NOTICE:
If the other system isn’t a 12-volt system with a negative \
ground, both vehicles can be damaged.
2. Get the vehicles close enough so the jumper cables can reach, but be
sure the vehicles aren’t touching each other. If they are, it could cause
a
ground connection you don’t want. You wouldn’t be able to start your
vehicle, and the bad grounding could damage the electrical syst\
ems.
You could be injured if the vehicles roll, Set the parking brake
firmly
on each vehicle. Put an automatic transmission in “P” (Park)\
or a
manual transmission
in “N’ (Neutral). If you have a four-wheel drive
vehicle with
a manual transfer case shift lever, be sure the transfer case
is not in “N’ (Neutral).
3. Turn off the ignition on both vehicles. Turn off all lights t\
hat aren’t
needed, and radios. This will avoid sparks and help save both batteries.
And it could save your radio!
I NOTICE:
I
If you leave your radio on, it could be badly damaged. The
repairs wouldn’t be covered by your warranty.
4. Open the hoods and locate the batteries. Find the positive (+) and
negative
(-) terminals on each battery.

Before you connect the cables, here are some basic things you should \
how. Positive (+) will go to positive (+) and negative (-) will go to
negative
(-) or SL metal engine part. Don’t. connect (+) to (-) or you’ll

Your use of gasoline with deposit control additives will help prevent
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 Motc
recommends that you use gasolines with these blending niaterials,
sucn 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 vehi\
cle
emissions. General Motors recommends that you use reformulated g\
asoline.
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 ma\
jor oil
company that does business in the country where you’ll be d\
riving.
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).

have proper venting, and your fuel tank and emissions system
might be damaged.
Checking Things Under fhe Hood

Downloaded from www.Manualslib.com manuals search engine 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
rninutes 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.
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 section explains what kind of oil to use.
For crankcase capacity, see “Capacities and Specifications” in the Index.

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 and the
PCV air tube is properly seated in the left hand valve cover.
Refer to
the Maintenance Schedule to determine when to replace 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 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. 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 a
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.
