The Certificatioflire label is found on the driver’s door lock pillar. The
label shows the size of your original tires and the inflation pressures needed
to obtain the gross weight capacity of your vehicle. This is called the
GVWR (Gross Vehicle Weight Rating). The GVWR includes the weight of
the vehicle, all occupants, fuel, cargo and trailer tongue weight, if pulling a
trailer.

NOTICE:
Pulling a trailer improperly can damage your vehicle and result\

in costly repairs not covered by your warranty.
To pull a trailer
correctly, follow the advice in this part, and see your
GM dealer
for important information about towing a trailer with your
vehicle.
Most vehicles are ready for some trailer towing. If yours was built with
trailering options, as many are, it’s ready for heavier trailers. But trailering
is different than just driving your vehicle by itself. Trailering means changes
in handling, durability, and fuel economy. Successful, safe trailering takes
correct equipment, and it has
to be used properly.
That’s the reason for this part. In it are many time-tested, important
trailering tips and safety rules. Many of these are important for your safety
and that
of your passengers. So please read this section carefully before you
pull a trailer.
If You Do Decide To Pull A Trailer
If you do, here are some important points.
There are many different laws, including speed limit restrictions,
having to do with trailering. Make sure your rig will be legal, not only
where you live but also where you’ll be driving.
A good source for this
information can be state or provincial police.
Consider using a sway control if your trailer will weigh 2,000 pounds
(900 kg) or less. You should always use a sway control if your trailer
will weigh more than
2,000 pounds (900 kg). You can ask a hitch
dealer about sway controls.

This vehicle has a clutched engine cooling fan. When the clutch is engaged,
the fan spins faster to provide more air to cool the engine. In most every day
driving conditions the clutch is not engaged. This improves fuel economy
and reduces fan noise. Under heavy vehicle loading, trailer towing and/or
high outside temperatures, the fan speed increases when
the clutch engages.
So you may hear an increase in fan noise. This is normal and should not be
mistaken as the transmission slipping or making extra shifts. It is merely the
cooling system functioning properly. The fan will slow down when
additional cooling is not required and the clutch disengages.
You may also hear this fan noise when you start the engine. It will go away
as the fan clutch disengages.
if a Tire Goes Flat
It’s unusual for a tire to “blow out” while you’re driving, especially if you
maintain your tires properly. If air goes out of
a tire, it’s much more likely to
leak out slowly. But if you should ever have a “blowout,” here are a few tips
about what to expect and
what to do:
If a front tire fails, the flat tire
will create a drag that pulls the vehicle
toward that side. Take your foot off the accelerator pedal and grip the
steering wheel firmly. Steer to maintain lane position, then gently brake to a
stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like a skid and may
require the same correction you’d use in a skid. In any rear blowout, remove
your foot from
the accelerator pedal. Get the vehicle under control by
steering the way you want the vehicle to go. It may be very bumpy and
noisy, but you can still steer. Gently brake to a stop, well off the road if
possible.
If a tire goes flat, the next part shows how to use your jacking equipment to
change a flat tire safely.

Doing Your Own Service Work
If you want to do some of your own service work, you’ll want to get the
proper
GM Service Manual. It tells you much more about how to service
your vehicle than this manual can.
To order the proper service manual, see
“Service Publications” in the Index.

Downloaded from www.Manualslib.com manuals search engine You should keep a record with all parts receipts and list the mileage and the
date
of any service work you perform. See “Maintenance Record” in the
Index.
NOTICE:
If you try to do your own service work without knowing enough
about it, your vehicle could be damaged.
Fuel
The 8th digit of your vehicle identification number (VIN) shows the code
letter for your engine. You will find the VIN at the top left
of your
instrument panel. (See “Vehicle Identification Number”
in the Index.)
Use regular unleaded gasoline rated at 87 octane or higher. With the
4.3L
(Code W) engine, use premium unleaded gasoline rated at 9 1 octane or
higher for high power performance, when towing
a trailer or with a high
payload requirement. But when operating with a light load
as a normal
condition, you may use middle grade or regular unleaded gasolines.
The gasoline you use should meet specifications
ASTM D48 14 in the
United States and CGSB
3.5-92 in Canada. These fuels should have the
proper additives,
so you should not have to add anything to the fuel.
In the United States and Canada, it’s easy to be sure you get the right kind
of gasoline (unleaded). You’ll see UNLEADED right on the pump. And
only unleaded nozzles will fit into your vehicle’s filler neck.
Be sure the posted octane
is at least 91 for premium, 89 for middle grade
and 87 for regular. If the octane
is less than 87, you may get a heavy

Downloaded from www.Manualslib.com manuals search engine knocking noise when you drive. If it’s bad enough, it can damage your
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 normal,
and
you don’t have to buy a higher octane fuel to get rid of it. It’s the heavy,
constant knock that means
you have a problem.
What about gasoline with blending materials that contain oxygen
(oxygenates), such as MTBE or alcohol?
MTBE is “methyl tertiary-butyl ether.” Fuel that is no more than 1 5%
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.
NOTICE:
Fuel that is more than 5% methanol is bad for your vehicle.
Don’t use it. It can corrode metal parts in your fuel syst\
em and also damage plastic and rubber parts. That damage wouldn’t b\
e
covered under your warranty. And even at
5% or less, there
must be “cosolvents” and corrosion preventers in this fuel\

to
help avoid these problems.
Gasolines for Cleaner Air
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.

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.

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.
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.
