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:
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.
Hill and Mountain Roads
Driving on steep hills or mountains is different from
driving in flat or rolling terrain.

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 to
THIRD (3) and
reduce your speed to around
45 mph (70 km/h) to reduce
the possibility of engine and transaxle overheating.
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
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 PARK (P).
5. Release the regular brakes.
PARK (P) yet.
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.

10. 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.
11. Now start the vehicle with the good battery and run
12. Try to start the vehicle with the dead battery.
the engine for a
while.
If it won’t start after a few tries, it probably needs
service.
13. Remove the cables in reverse order to prevent
electrical shorting. Take care that they don’t touch
each other or any other metal.

Towing Your Vehicle
Try to have a Buick dealer or a professional towing
service tow your Park Avenue. See “Roadside
Assistance’’ in the Index.
If your vehicle has been changed or modified since it
was factory-new by adding after-market 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 can only be towed with certain
equipment, as described later in this section.
0 That your vehicle has front-wheel drive.
The make, model and year of your vehicle.
0 Whether you can still move the shift lever.
0 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.
I
To help avoid injury to you or others:
Never let passengers ride in a vehicle that is
0 Never tow faster than safe or posted speeds.
Never tow with damaged parts not
fully secured.
Never get under your vehicle after it has
been lifted by the tow truck.
Always secure the vehicle on each side with
separate safety chains when towing it.
Never use J-hooks. Use T-hooks instead.
being towed.

ProCarManuals.com

A vehicle can fall from a car carrier if it isn’t
adequately secured. This can cause a collision,
serious personal injury and vehicle 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
edges underneath the towed vehicle. Always use
T-hooks inserted in the T-hook slots. Never use
J-hooks. They will damage drivetrain and
suspension components.
When your vehicle is being towed, have the ignition
key in the
OFF position. 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 (N) 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, be sure to follow the speed and distance
restrictions later in
this section .or your transaxle will be
damaged.
If these limits must be exceeded, then the
front wheels have to be supported on a dolly.

If No Steam Is Coming From Your Engine
If you get the overheat warning but see or hear no
steam, the problem may not be too serious. Sometimes
the engine can get a little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no sign of steam,
try this for
a minute or so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to NEUTRAL (N);
otherwise, shift to the highest gear while
driving
-- AUTOMATIC OVERDRIVE (0)
or THIRD (3).
If you no longer have the overheat warning, you
can drive. Just to be safe, drive slower for about
10 minutes. If the warning doesn’t come back on,
you can drive normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see if
the warning stops.
But then, if you still have the
warning,
turn ofthe engine and get everyone out of the
vehicle
until it cools down.
You may decide not to lift the hood but to get service
help right away.

The coolant level should be at or above the FULL
COLD mark.
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water pump or somewhere else in
the cooling system.
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine if there is
a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
I NOTICE:
Engine damage from running your engine
without coolant isn’t covered by your warranty.
If there seems to be no leak, with the engine on, check to
see
if the electric engine fans are running. If the engine
is overheating, both fans should be running.
If they
aren’t, your vehicle needs service.

Doing Your Own Service Work
If you want to do some of your own service work, you’ll
want to get the proper Buick Service Manual. It tells you
much more about how to service your Buick than this
manual can.
To order the proper service manual, see
“Service and Owner Publications” in the Index.
Your vehicle has an air bag system. Before attempting to
do your own service work,
see “Servicing Your Air
Bag-Equipped Buick” in the Index.
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.

You can be injured and your vehicle could be
damaged if you
try to do service work on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, the proper replacement parts
and tools before you attempt any vehicle
maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused.
If you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.
Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your Buick dealer before adding equipment to the
outside of your vehicle.
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.)
If you have the 3800 engine
(VJN Code K), use regular
unleaded gasoline rated at 87 octane or higher.
If you’re
using fuel rated at the recommended 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.
