Run your engine only as long as you must. This saves
fuel. When you run the engine, make
it go a little faster
than just idle. That
is, push the accelerator slightly. This
uses less fuel for the heat that you get and it keeps
the
battery charged. You will need a well-charged battery to
restart the vehicle, and possibly for signaling later on
with your headlights. Let the heater run for awhile.

Then, shut the engine off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this only when you
feel really uncomfortable
from the cold. But do it as little
as possible. Preserve the
fuel as long as you can.
To help keep warm, you can get
out
of the vehicle and do some fairly vigorous exercises
every half hour
or so until help comes.
If You’re Stuck in Deep Snow
This manual explains how to get the vehicle out of deep
snow without damaging it. See “Rocking Your Vehicle”
in the Index.
Towing a Trailer
(n CAUTION:
If you don’t use the correct equipment and drive
properly, you can
lose control when you pull a
trailer. For example,
if the trailer is too heavy, the
brakes may not work well
-- or even at all. You
and your passengers could be seriously injured.
Pull a trailer only if you have followed all the
steps
in this section.
I NOTICE:
Pulling a trailer improperly can damage your
vehicle and result
in costly repairs not covered
by your warranty.
To pull a trailer correctly, follov
the advice in this section. ‘I
Your vehicle can tow a trailer. To identify what the
vehicle trailering capacity is for your vehicle, you
should read the information in “Weight
of the Trailer”
that appears later in this section. 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 section. 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.
Load-pulling components such as the engine, transaxle,
wheel assemblies, and tires are forced to work harder
against the drag of the added weight. The engine is
required to operate at relatively higher speeds and under
greater loads, generating extra heat. What’s more, the
170

trailer adds considerably to wind resistance, increasing
the pulling requirements.
All of that means changes in:
Handling
Durability
0 Fuel economy
If
You Do Decide To Pull A Trailer
If you do, here are some important points.
There are many different laws 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.
0 Consider using a sway control.
You can ask a hitch dealer about sway controls.
Don’t tow a trailer at all during the first 500 miles
(800 km) your new vehicle is driven. Your engine,
axle or other parts could be damaged.
Then, during the first 500 miles (800 km) that you
tow a trailer, don’t drive over 50 mph (80 km/h) and
don’t make starts at full throttle. This helps your engine and other
i)a’rts of your
vehicle wear in at the
heavier loads.
Three important considerations have to do with weight:
Weight of the Trailer
How heavy can a trailer safely be?
It should never weigh more than
1,000 pounds (450 kg).
But even that can be too heavy.
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull
a
trailer are all important. And, it can also depend on any
special equipment that you have on your vehicle.
You can ask your dealer for our trailering information or
advice, or

Fuel
Use regular unleaded gasoline rated at 87 octane or
higher. It should meet specifications ASTM D4814 in
the
U.S. 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
U.S. 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
87. If the octane is
less than
87, you may get a heavy knocking noise when
you drive. If it’s bad enough, it can damage your engine.
If you’re using fuel rated at
87 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 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.
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 system and also damage
plastic and rubber parts. That damage wouldn’t
be 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.
I
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
215
ProCarManuals.com
Page 218 of 308

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 detergents 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).

A CAUTION:
If you get gasoline on you and then something
ignites it, you could be badly burned. Gasoline
can spray out on you if you open the fuel filler
cap too quickly, This spray can happen if your
tank is nearly full, and: is more likely in hot
weather. Open the fuel filler cap slowly and wait
for any “hiss” noise to stop. Then unscrew the
cap all the way.
When you put the cap back on, turn it to the right until
you hear a clicking noise.
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
Hood Release
To open the hood, first pull
the handle inside the
vehicle. It is located on the
floor next to the driver’s
seat.

Before closing the hood, be sure all the filler caps are on
properly.
Then just pull the hood down and close it firmly.
Engine Oil
If the “LOW OIL” light on the instrument panel comes
on, it means you need to check your engine oil level
right away.
You should check your engine oil level
regularly, the light
is an added reminder. 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.
The dipstick is located near the front and center
of the
engine compartment.
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.
