Downloaded from www.Manualslib.com manuals search engine 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, and 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.
Trailer Light Wiring
See “Trailer Wiring Harness” in the Index.
Power Winches
If you wish to use a power winch on your vehicle, only use it when your
vehicle
is stationary or anchored.
! NOTICE:
~ When operating a power winch on your vehicle always leave the \
l transmission in the neutral position. Do not leave an automatic
transmission in
P (Park) or a manual transmission in gear or the
transmission may be damaged.
Use the regular brakes, set the parking brake or block the wheels to keep
your vehicle from rolling.

If you carry reflective triangles, you can set one up at the side of the road
about
300 feet (100 m) behind your vehicle.
Jump Starting
If your battery has run down, you may want to use another vehicle and some
jumper cables to start your vehicle. But please follow the steps below to
do
it safely.
NOTICE:
Ignoring these steps could result in costly damage to your
vehicle that wouldn’t be covered by your warranty.
Trying to start your vehicle by pushing or pulling it could damage
your vehicle, even
if you have a manual transmission. And if you
~ have an automatic transmission, it won’t start that way.
To Jump Start Your Vehicle:
1. Check the other vehicle. It must have a 12-volt battery with a negative
ground system.
NOTICE:
If the other system isn’t a 12-volt system with a negative
ground, both vehicles can be damaged.

3.
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
ground connection you don’t want. You wouldn’t be able to start you1
vehicle, and the bad grounding could damage the electrical systems.
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
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).
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
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.
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

Your use of gasoline with deposit control additives will help prevent
deposits from forming in your engine and fuel system. That helps 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 (VIN).

If you need a new cap, be sure to get the right type. Your dealer
can get one for you. If you get the wrong type, it may not fit or
have proper venting, and your fuel tank and emissions system
might be damaged.
Checking Things Under the Hood
Then go to the front of
the vehicle and release
the secondary hood
release.

Downloaded from www.Manualslib.com manuals search engine Remove the hood prop
from
the slot in the
hood and return the
prop to its retainer.
Then just pull the
hood down and close
it firmly.
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.
I 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 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.
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.

Downloaded from www.Manualslib.com manuals search engine 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.
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, starting
a fire. Be sure to get
an accurate reading if you check your transmission fluid.
6-15

Downloaded from www.Manualslib.com manuals search engine Wait at least 30 minutes before checking the transmission fluid level if you
have been driving:
0 When outside temperatures are above 90°F (32°C).
At high speed for quite a while.
0 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).
To check transmission fluid 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 “D” (3rd Gear) 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 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.
To check the fluid hot or cold
0 Park your vehicle on a level place.
0 With the parking brake applied, place the shift lever in “P’ (Park).
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 “P” (Park).
Let the engine run at idle for three minutes or more.
