Night Vision
No one can see as well at night as in the daytime. But as
we get older these differences increase.
A SO-year-old
driver may require at least twice as much light to see the
same thing at night as a 20-year-old.
What you do in the daytime can also affect your night
vision. For example, if you spend the day
in bright
sunshine you are wise to wear sunglasses. Your eyes will
have less trouble adjusting to night.
But if you’re driving, don’t wear sunglasses at night.
They may cut down on glare from headlights, but
they
also make a lot of things invisible that should remain
visible
- such as parked cars, obstacles, pedestrians, or
even trains blocking railway crossings. You may want to
put on your sunglasses after you have pulled into
a
brightly-lighted service or refreshment area. Eyes shielded from that glare may adjust more quickly to
darkness back on the road. But be sure to remove your sunglasses before you leave the service area.
You can be temporarily blinded by approaching lights. It
can take a second
or two, or even several seconds, for
your eyes to readjust to the dark. When you are faced
with severe glare (as from
a driver who doesn’t lower
the high beams, or a vehicle with misaimed headlights), slow down
a little. Avoid staring directly into the
approaching lights. If there is a line of opposing traffic,
make occasional glances over the line of headlights to
make certain that one of the vehicles isn’t starting to
move into your lane. Once you are past the bright lights,
give your eyes time to readjust before resuming speed.
High Beams
If the vehicle approaching you has its high beams on,
signal by flicking yours to high and then back
to low
beam. This is the usual signal to lower the headlight
beams. If the other driver still doesn’t lower the beams,
resist the temptation to put your high beams on. This only makes two half-blinded drivers.
On a freeway, use your high beams only in remote areas
where you won’t impair approaching drivers. In some
places, like cities, using high beams is illegal.
When you follow another vehicle on a freeway or
highway, use low beams. True, most vehicles now have day-night mirrors that enable the driver to reduce glare. But outside mirrors are not of this type and high beams
from behind can bother the driver ahead.

Driving a Long Distance
Although most long trips today are made on freeways,
there are still many made on regular highways. Long-distance driving on freeways and regular
highways is the same in some ways. The trip has to be
planned and the vehicle prepared, you drive at
higher-than-city speeds, and there are longer turns
behind the wheel. You’ll enjoy your trip more if you and
your vehicle are in good shape. Here are some tips for a
successful long trip.
Before Leaving on a Long Trip
Make sure you’re ready. Try to be well rested. If you
must start when you’re not fresh
-- such as after a day’s
work
-- don’t plan to make too many miles that first part
of the journey. Wear comfortable clothing and shoes you
can easily drive
in.
Is your vehicle ready for a long trip? If you keep it
serviced and maintained,
it’s ready to go. If it needs
service, have it done before starting out. Of course,
you’!! find experienced and able service experts in
Buick dealerships all across North America. They’ll be
ready and willing to help
if you need it.
Here are some things you can check before a trip:

Windshield Washer Fluid: Is the reservoir full? Are
all windows clean inside and outside?
Wiper Blades: Are they in good shape?
Fuel, Engine Oil. Other Fluids: Have
you checked
all levels?
Lights: Are they all working? Are the lenses clean?
- Tires: They are vitally important to a safe,
trouble-free trip.
Is the tread good enough for
long-distance driving? Are the tires all inflated to the
recommended pressure?
Weather Forecasts: What’s the weather outlook
along your route? Should you delay your trip
a short
time to avoid a major storm system?
Maps:
Do you have up-to-date maps?
On the Road
Unless you are the only driver, it is good to share the
driving task with others. Limit turns behind the wheel to
about
100 miles (160 km) or two hours at a sitting.
Then, either change drivers or stop for some refreshment
like coffee, tea
or soft drinks and some limbering up.
But do stop and move around. Eat lightly along the way.
Heavier meals tend to make some people sleepy.

On two-lane highways or undivided multilane highways
that do not have controlled access, you’ll want to watch for some situations not usually found on freeways.
Examples are: stop signs and signals, shopping centers with direct access to the highway, no passing zones and school zones, vehicles turning left and right off the road,
pedestrians, cyclists, parked vehicles, and even animals.
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.

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 frequently
and your instruments from time
to time. This can
help you avoid
a fixed stare.
Wear good sunglasses in bright light. Glare can
cause drowsiness. But don’t wear sunglasses at
night. They will drastically reduce your overall
vision
at the very time you need all the seeing power
you have.
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.
As in any driving situation, keep pace with traffic and
allow adequate following distances.

Parking on Hills
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 “P7’
(Park) yet.
2. Have someone place chocks under the trailer 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 then shift to
“P” (Park).
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;
Shift into a gear; and
0 Release the parking brake.
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, belts, 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 these sections before you
start
your trip.
Check periodically to see that all hitch nuts and bolts are
tight.

8. Now connect the black negative (-) cable to the good
battery’s negative
(-) terminal.
Don’t let the other end touch anything until the next
step. The other end
of the negative cable doesn’t go
to the dead battery. It goes to
a heavy unpainted
metal part on the engine
of the vehicle with the dead
battery.
9. Attach the cable at least 18 inches (45 cm) away
from the dead battery, but
not near engine parts that
move. The electrical connection is just
as good there,
but the chance of sparks getting back to the battery
is
much less.

If it won’t start after a few tries, it probably needs

electrical shorting. Take care that they don't touch
each other

Towing Your Car
Try to have a GM dealer or a professional towing
service tow your Buick. The usual towing equipment is
a sling-type
(A) or a wheel-lift (B) or car carrier (C) tow
truck.

If your vehicle has been changed or modified since it
was factory-new by adding aftermarket items like fog
lamps, aero skirting, or special tires and wheels, these
instructions and illustrations may not be correct.

Before you do anything, turn on the hazard warning
flashers.
When you call, tell the towing service:
That your vehicle has front-wheel drive.
The make, model, and year of your vehicle.
Whether you can still move the shift lever.
If there was an accident, what was damaged.
When the towing service arrives, let
the tow operator
know that this manual contains detailed towing instructions and illustrations. The operator may want to
see them.
A CAUTION:
To help avoid injury to you or others:

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 towing service.
Do not use the vehicle’s steering
column lock for this. The transaxle should be in Neutral
and the parking brake released.
Don’t have your vehicle towed on the front wheels,
unless
you must. If the vehicle must be towed on the
front wheels, don’t
go more than 55 mph (88 kph) or
farther than
500 miles (800 km) or your transaxle will
be damaged.
If these limits must be exceeded, then the
front wheels have to be supported on a dolly.

A CAUTION:
A vehicle can fall from a car carrier if it isn’t
properly secured, This can cause a collision,
serious personal injury and vehlcle damage. The
vehicle should be tightly secured with chains
or
steel cables before it is transported.
Don’t use substitutes (ropes, leather straps,
canvas webbing, etc.) that can be cut by sharp
zdges underneath the towed vehicle.
