Try to have a GM dealer or a professional towing service tow your vehicle.
They can provide the right equipment and know how to tow it without
damage.
If your vehicle has been changed since it was factory-new, by adding things
like fog lamps, aero skirting, or special tires and wheels, th\
ese things could
be damaged during towing.
Before you do anything, turn on the hazard warning flashers.
When you call, tell the towing service:

When your vehicle is being towed, have the ignition key off. The steering
wheel should be clamped in a straight-ahead position with a clamping device
designed for a towing service. Do not use the vehicle's steeri\
ng column
lock for this. The transmission (either automatic or manual) should\
be in
N (Neutral) and the transfer case (either manual shift or elec\
tronic shift), if
you have one, should be in 2 WHEEL (two-wheel drive). The parking brake
should be released.

If the vehicle must be towed on the rear wheels, don't go more than 35 mph
(56 km/h) or farther than 50 miles (80 km) or your transmission will be
damaged.
If these limits must be exceeded, then the rear drive wheels have\

to be supported on a dolly.
If your vehicle has the four-wheel-drive option, a dolly
MUST be used under
the rear wheels when towing from the front.

If No Steam Is Coming From Your Engine:
If you get the overheat warning but see or hear no steam, the problem may
not be too serious. Sometimes the engine can get a little
too hot when you:
Climb a long hill on a hot day.
Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam, try this for a minute
or so:
1. If you have an air conditioner, turn it off.
2. Turn your heater to full hot at the highest fan speed and open the

window as necessary.
If you no longer have the overheat warning, you can drive. Just to
be safe,
drive slower for about ten minutes. If the warning doesn't com\
e back on, you
can drive normally.
If the warning continues, pull over, stop, and park your vehicle \
right away.
If there's still no sign of steam, push the accelerator until the engine speed is
about twice as fast as normal idle speed. Bring the engine sp\
eed back to
normal idle speed after
two or three minutes. Now see if the warning stops.
But then,
if you still have the warning, TURN OFF THE ENGINE AND GET
EVERYONE
OUT OF THE VEHICLE until it cools down.
You may decide
not to lift the hood but to get service help right away.

Your General Motors dealer knows your vehicle best and wants you to\
be
happy with it. We hope you’ll go to your dealer for all your service needs.
You’ll get genuine GM parts and GM-trained and supported ser\

We hope you’ll want
to keep your GM vehicle all GM. GM parts have one of
these marks:
Doing Your Own Service Work
If you want to do some of your own service work, you’ll want to get the
proper General Motors Service Manual. It tells you much more a\
bout how to
service your vehicle than this manual can.
To order the proper service
manual, see “Service Publications” in the Index.
You should keep
a record with all parts receipts and list the mileage and
date of any service work you perform. See “Maintenance Record” \
in the
Index.
Yolu can be injured
if you try to do service work on a vehicle without
knowing enou’glh about it.
9 Be sure you have sufficient know18edge, experience, and the
proper replacement parts and tools before you attempt any
vehicle maintenance
task.
@~ Be sure to use th’e proper nuts, bolts and other fasteners.
“English” and “metric” fasEeners can be easily confused.
If you
use the wrong fasteners, parts can later break ‘ar fall
off. You
could be hurt.

Downloaded from www.Manualslib.com manuals search engine If you’re using fuel rated at 91 octane or higher and you still hear heavy
knocking, your engine needs service. But don’t worry
if you hear a little
pinging noise when you’re accelerating or driving up a hill. That’s nor\
mal, and
you don’t have to buy a higher octane fuel to get rid of pinging. It’s the
heavy, constant knock that means you have a problem.
What about gasoline with blending materials that contain oxygen,\
such as
MTBE or alcohol?
MTBE is “methyl tertiary-butyl ether.” Fuel that is no more than
15% MTBE is
fine for your vehicle.
Ethanol is ethyl or grain alcohol. Properly-blended fuel that is no more than
10% ethanol is fine for your vehicle.
Methanol is methyl or wood alcohol.

5% methanol is bad for your vehicle. Don’t use il

Gasolines for Cleaner Air
Your use of gasoline with detergent 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 materials called oxygenates. General
Motors recommends that you use gasolines with these blending ma\
terials,
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 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
detergents and oxygenates, and
if they have been reformulated to reduce
vehicle emissions.
