time. A green arrow means you may drive in that lane.
Look for the signs posted to warn drivers what hours
and days these systems are in effect.
Pavement Markings
NO
PASSING
ZONE
Pavement markings add to traffic signs and signals.
They give information to drivers without taking
attention from the roadway. A solid yellow line
on your
side of the road
or lane means “don’t cross.”
Your Own Signals
Drivers signal to others, too. It’s not only more polite,
it’s safer to let other drivers know what you are doing.
And in some places the law requires driver signals.
Turn and lane change signals. Always signal when you
plan to turn or change lanes.
If necessary, you can use hand signals out the window:
Left arm straight
out for a left turn, down for slow or
about-to-stop, and up for a right turn.
Slowing down. If time allows, tap the brake pedal once
or twice in advance of slowing or stopping. This warns
the driver behind you.
Disabled. Your four-way flashers signal that your
vehicle
is disabled or is a hazard. See “Hazard Warning
Flashers” in the Index.
Traffic Officer
The traffic police officer is also a source of important
information. The officer’s signals govern, no matter
what the traffic lights or other signs say.
The next section discusses some of the road conditions
you may encounter.
Defensive Driving
The best advice anyone can give about driving is: Drive
defensively.
Please start with a very important safety device in your
Buick: Buckle up. (See “Safety Belts” in the Index.)
ProCarManuals.com

When you drive into a curve at night, it’s harder to see
the road ahead of you because it bends away from the
straight beams of your lights. This is one good reason to
drive slower.
Steering in Emergencies
There are timi% when steering can be more effective
than braking. For example,
you come over a hill and
find a truck stopped in your lane, or a car suddenly pulls
out from nowhere, or a child darts out from between
parked cars and stops right
in front of you. You can
avoid these problems by braking
-- if you can stop in
time. But sometimes you can’t; there isn’t room. That’s
the time for evasive action
-- steering around the
problem.
Your Buick can perform very well
in emergencies like
these. First apply your brakes. It is better to remove as
much speed as you can from a possible collision. Then
steer around the problem, to the left or right depending
on the space available.
An emergency like this requires close attention and a
quick decision. If you are holding the steering wheel at
the recommended 9 and 3 o’clock positions, you can
turn it a full 180 degrees very quickly without removing
either hand. But you have
to act fast, steer quickly, and just as
quickly straighten the wheel once you have
avoided the object. You must then be prepared to steer
back
to your original lane and then brake to a controlled
stop.
Depending on your speed, this can be rather violent for
an unprepared driver. This is one of the reasons driving
experts recommend
that you use your safety belts and
keep both hands on the steering wheel.
I
D
The fact that such emergency situations are always
possible
is a good reason to practice defensive driving at
all times.

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;
0 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, 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 these sections before
you start
your trip.
Check periodically to see that all hitch nuts and bolts are
tight.

A CAUTION:
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
I underhood electric fan. I
A CAUTION:

Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber.
You or others
could be burned. Be careful not to drop or spill
things that will burn onto
a hot engine.

Before closing the hood, be sure all the filler caps are on
properly. Then just pull the hood down and close it
firmly.
3800 V6 Supercharged Engine
Your Park Avenue Ultra has a 3800 V6 Supercharged
engine. Buick chose supercharging rather than
turbocharging because Buick emphasizes smooth,
refined power.
The Supercharger is a device which is designed
to pump
more air into the engine than it would normally use.
This air mixed with fuel, creates increased engine
power. Since the Supercharger is a pump and
is driven
from an engine accessory drive belt, increased pressure
is available at all driving conditions.
250
ProCarManuals.com

The powertrain control module (PCM), works with a
vacuum control to regulate the increased pressure
required during specific driving conditions. When this
increased pressure or boost, is not desired such as during
idling and light throttle cruising, the excess air that the
Supercharger is pumping is routed through a bypass. All
of these controls, working together provide high
performance character and fuel efficiency in the
3800
V6 Supercharged Buick engine.
The power steering pump uses a remote reservoir
mounted on the throttle and cruise control cable bracket.
See “Maintenance Schedule’’ in the Index for when you
should check the fluid.
The supercharged
3800 engine uses two accessory drive
belts. One belt drives the generator and the power
steering pump. The second belt drives the supercharger,
coolant pump and air conditioning compressor. Each
belt has
its own tensioner and idler pulley. See
“Maintenance Schedule’’ in the Index for when you
should check the accessory drive belts and supercharger
oil level. Have your dealer check the oil level in the
supercharger.
Engine Oil
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 engine oil dipstick is
directly behind the engine
fan. Turn
off the engine and
give the oil a few minutes
to get back down into the
oil pan. If you don’t, the oil
dipstick might not &ow the
actual level.

The tire has a puncture, cut, or other damage that
can’t be repaired well because
of the size or location
of the damage.
Buying New Tires
To find out what kind and size of tires you need, look at
the Tire-Loading Information label.
The tires installed
on your vehicle when it was new had
a Tire Performance Criteria Specification (TPC Spec)
number on each tire’s sidewall. When you get
new tires,
get ones with that same TPC Spec number. That way,
your vehicle will continue to have tires that are designed
to give proper endurance, handling, speed rating,
traction, ride and other things during normal service on
your vehicle.
If your tires have an all-season tread
design, the TPC number will be followed by a
“MS”
(for mud and snow).
If you ever replace your tires with those not having a
TPC Spec number, make sure
they are the same size,
load range, speed rating and construction type (bias,
bias-belted or radial) as your original tires.
. CAUTION:
Xing tires could cause you to lose control
hile driving. If you mix tires ob different sizes or
types (radial and bias-betted tires;), the vehicle
may not handle properly, and you coutd have a
crash.
Be sure to use the same size and type
tires on all wheels.

Uniform Tire Quality Grading
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration which grades tires by
treadwear, traction and temperature performance. (This
applies only to vehicles sold
in the United States.)
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded
150 would wear one and a half (1

Cleaning Speaker Covers
Vacuum around a Delco-Bose speaker cover gently, so
that the speaker won’t be damaged. If something gets on
one
of them, follow the steps earlier under “Using
Solvent-Type Cleaner on Fabric.” Use as little solvent as
you can.
Care of Safety Belts
Keep belts clean and dry. Don’t
use abrasive cleaners on glass, because they may
caus.e scratches. Avoid placing decals on the inside rear
window, since they may have to be scraped
off later. If
abrasive cleaners are used on the inside of the rear
window, an electric defogger element may be damaged.
Any temporary license should not be attached across the
defogger grid.
Cleaning .the Outside of the
Windshield and Wiper Blades
A CAUTION:
Do not bleach or dye safety belts. If you do, it
may severely weaken them. In a crash they might
not be able to provide adequate protection. Clean
safety belts only with mild soap and lukewarm
I I
Glass
Glass should be cleaned often. GM Glass ueaner (GM
Part
No. 1050427) or a liquid household glass cleaner
will remove normal tobacco smoke and dust films. If
the windshield is not clear after using the windshield
washer, or if the wiper blade chatters when running, wax
or other material may be
on the blade or windshield.
Clean the outside of the windshield with GM
Windshield Cleaner, Bon-Ami Powders (GM Part
No.
105001 1). The windshield is clean if beads do not form
when you rinse it with water.
Clean the blade by wiping vigorously with a cloth
soaked in
full strength windshield washer solvent. Then
rinse the blade with water.
Wiper blades should be checked on
a regular basis and
replaced when worn.
