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
less 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:
a 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. Driving
on steep hills or mountains is different from
driving in flat or rolling terrain.
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.

If you drive regularly in steep country, or if you’re
planning
to visit there, here are some tips that can make
your trips safer and more enjoyable.
0 Keep your vehicle in good shape. Check all fluid
levels and also the brakes, tires, cooling system
and transaxle. These parts can work hard
on
mountain roads.
Know how to go down hills. The most important
thing
to know is this: let your engine do some of the
slowing down. Shift to a lower gear when you
go
down a steep or long hill.
7-
If you don’t shift down, your brakes could
get
so hot that they wouldn’t work well. You
would then have poor braking or even none going
down
a hill. You could crash. Shift down to let
your engine assist your brakes on a steep
downhill slope.
U
Coasting downhill in NEUTRAL (N) or with the
ignition
off is dangerous. Your brakes will have to
do all the work of slowing down. They could get
so
hot that they wouldn’t work well. You would then
have poor braking
or even none going down a hill.
You could crash. Always have your engine running
and your vehicle in gear when you go downhill.

Know how to go uphill. You may want to shift down
to a lower gear. The lower gears help cool your engine
and transaxle, and you can climb the hill better.
Stay in your own lane when driving on two-lane
roads in hills or mountains. Don’t swing wide or cut
across the center
of the road. Drive at speeds that let
you stay in your own lane.
As you go over the top of a hill, be alert. There could be
something in your lane, like a stalled car or
an accident.
You may see highway signs
on mountains that warn of
special problems. Examples are long grades, passing or
no-passing zones,
a falling rocks area or winding
roads. Be alert to these and take appropriate action.

Tie a red cloth to your vehicle to alert police that
you’ve been stopped by the snow.
Put on extra clothing or wrap a blanket around you.
If you have no blankets or extra clothing, make body
insulators
from newspapers, burlap bags, rags, floor
mats
-- anything you can wrap around yourself or
tuck under your clothing to keep warm. Snow can
trap exhaust gases under your vehicle.
This can cause deadly
CO (carbon monoxide) gas
to get inside.
CO could overcome you and kill
you. You can’t see it or smell
it, so you might not
know it is in your vehicle. Clear
away snow from
around the base
of your vehicle, especially any
that
is blocking your exhaust pipe. And check
around again from time to time to be sure snow
doesn’t collect there.
Open
a window just a little on the side of the
vehicle that’s away from the wind. This will help
keep CO out.
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 headlamps. Let the heater run for a while.
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.
Loading Your Vehicle
Two labels on your vehicle show how much weight it
may properly calry. The Tire-Loading Information label
is inside the trunk lid. The label tells you the proper size,
speed rating and recommended inflation pressures for
the tires
on your vehicle. It also gives you important
information about the number of people that can be in
your vehicle and the total weight you can carry. This
weight is called the vehicle capacity weight and includes
the weight of all occupants, cargo and all
nonfactory-installed options.

Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or in
a crash.
Put things in the trunk of your vehicle. In a
trunk, put them as far forward as you can.
Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle
so that some of them are
above the tops of the seats.
Don’t leave an unsecured child restraint in
your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Don’t leave a seat folded down unless you
need to.
Towing a Trailer
I
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.
You may also damage your vehicle; the resulting
repairs would not be covered by your warranty.
Pull a trailer only if you have followed all the
steps in this section. Ask your dealer for advice
and information about towing a trailer with
your vehicle.
Do not tow a trailer if your vehicle is equipped with the
3800 L67 Supercharged engine.

Your vehicle can tow a trailer if it is equipped with the
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 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.
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
trailer adds considerably to wind resistance, increasing
the pulling requirements.
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. You can ask a hitch
dealer about sway controls.
Don’t tow a trailer at all during
the first 1,000 miles
(1 600 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 kdh) and
don’t make starts at full throttle. This helps your
engine and other parts of your vehicle wear
in at the
heavier loads.
Obey speed limit restrictions when towing a trailer.
Don’t drive faster than the maximum posted speed
for trailers (or no more than
55 mph (90 kmh)) to
save wear on your vehicle’s parts.

Making Thns
I NOTICE:
Making very sharp turns while trailering could
cause the trailer
to come in contact with the
vehicle. Your vehicle could be damaged. Avoid
making very
sharp turns while trailering.
When you’re turning with a trailer, make wider
turns than normal.
Do this so your trailer won’t strike
soft shoulders, curbs, road signs, trees or other objects.
Avoid jerky or sudden maneuvers. Signal well
in advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle may need a
different turn signal flasher and/or extra wiring. Check
with your Buick dealer. The green arrows on your
instrument panel will flash whenever you signal a turn
or lane change. Properly hooked up, the trailer lamps
will also flash, telling other drivers you’re about to turn,
change lanes
or stop.
When towing
a trailer, the green arrows on your
instrument panel will flash for turns even
if the bulbs on
the trailer are burned out. Thus, you may think drivers
behind you are seeing your signal when they are not. It’s
important to check occasionally to be sure the trailer
bulbs are still working.
Driving On Grades
Reduce speed and shift to a lower gear before you start
down
a long or steep downgrade. If you don‘t shift
down, you might have to use your brakes
so much that
they would get hot and no longer work well.
On
a long uphill grade, shift down and reduce your
speed to around
45 mph (70 km/h) to reduce the
possibility
of engine and transaxle overheating.

Parking on Hills 0 Shift into a gear; and
0 Release the parking brake.
You really should not park your vehicle, with a trailer
attached, on
a hill. If something goes wrong, your rig
could start to move. People can be injured, and both
your vehicle and the trailer can be damaged.
But if you ever have to park your rig on a hill, here’s
how to do it:
1. Apply your regular brakes, but don’t shift into
PARK (P) yet.
2. Have someone place chocks under the
trailer’s wheels.
3. When the wheel chocks are in place, release the
regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then apply your parking
brake, and shift to
PARK (P).
5. Release the regular brakes.
When You Are Ready to Leave After
Parking
on a Hill
1. Apply your regular brakes and hold the pedal down
while you:
Start your engine;
2. Let up on the brake pedal.
3. Drive slowly until the trailer is clear of the chocks.
4. Stop and have someone pick up and store the chocks.
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 transaxle fluid (don’t overfill),
engine oil, drive 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 this information
before you start your trip.
Check periodically
to see that all hitch nuts and bolts
are tight.
Engine Cooling When Trailer Towing
Your cooling system may temporarily overheat during
severe operating conditions. See “Engine Overheating”
in the Index.

2. 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
a ground
connection you don’t want. You wouldn’t be able to
start your vehicle, and the bad grounding could
damage the electrical systems.
To avoid the possibility of the vehicles rolling, set
the parking brake firmly on both vehicles involved in
the jump
start procedure. Put your automatic
transaxle in
PARK (P) before setting the
parking brake.
3. Turn off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter
or accessory power outlet. Turn off all lamps
that aren’t needed as well
as radios. This will avoid
sparks and help save both batteries. In addition, 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. (Your
vehicle’s battery is located toward the front
of the
passenger’s side
of the vehicle’s engine, underneath
a diagonal brace.)
An electric fan can start up even when the engine
is not running and can injure you. Keep hands, clothing and tools away
from any underhood
electric fan.
