Air Conditioning
The air conditioning has three settings. On very hot
days, open

escape. This reduces the amount of work your

This provides maximum cooling with the least amount
of work. This setting recirculates much of the air inside
your vehicle
so it maximizes your air conditioner’s
performance and fuel economy.
Norm
Use for normal cooling on hot days. This setting cools
outside air and directs
it through the instrument panel
outlets.
Bi-Lv (Bi-Level)
This setting is designed for use on sunny days where the
air is only moderately warm or cool.
On days like these,
the sun may adequately warm your upper body, but your
lower body may not be warm enough.
The Bi-level setting directs outside air into your vehicle
in two ways. Cool air is directed toward your upper
body through the front instrument panel outlets, while
slightly warmed air is directed through the heater outlet
at your feet.

Tires: They are vitally important
to a safe,

long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s

Maps:
Do you have ur>-to-date maps?
Highway Hypnosis
Is there actually such a condition as “highway hypnosis”?
Or is
it just plain falling asleep at the wheel? Call it
highway hypnosis, lack of awareness, or whatever.
There is something about an easy stretch
of road with the
same scenery, along with the hum of the tires on the road,
the drone of the engine, and the rush of the wind against
the vehicle that can make you sleepy. Don’t let
it happen
to you! If
it does, your vehicle can leave the road in
than a second, and
you could crash and be injured.
What can you do about highway hypnosis? First, be
aware that
it can happen.
Then here are some tips:

Make sure your vehicle is well ventilated, with a
comfortably cool interior.
Keep your eyes moving. Scan the road ahead and to
the sides. Check your rearview mirrors and your
instruments frequently.
If you get sleepy,
pull off the road into a rest, service,
or parking area and take a nap, get some exercise, or
both. For safety, treat drowsiness on the highway as
an emergency.

bags, rags, floor mats -- anything you can wrap around
yourself or tuck under your clothing to keep warm.
You can run the engine to keep warm, but be careful.
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.
Towing a Trailer
I NOTICE: I
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 section, and see your Buick
dealer for important information about towing a
trailer with your vehicle.
Your car can tow a trailer if it is equipped with 3.1L or
3.8L V6 engine and proper trailer towing equipment. 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 carefullv
before
you pull a trailer.

Fuel
Use regular unleaded gasoline rated at 87 octane or
higher. It should meet specifications ASTM
D48 14 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 (oxygenates), 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.
I 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.
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.
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).
