1994 BUICK PARK AVENUE power steering

Power Windows
Your power window controls are on the armrest. The
switch for the driver’s window has an express-down
feature. Pull
the switch back all the way, release it and
the window will lower automatically.
To stop the
window from lowering, push the switch forward.
To
partially open the window, pull the switch back and
quickly release it.
You may also have a lock out button. Push
LOCK to
disable the power window switches. This
will prevent
passengers from opening and closing the windows. The driver
can still control all the windows
with the switch
in
the locked position. Push UNLOCK to allow your
passengers to use their window switches again.
Horn
To sound the horn, press a pad with the horn symbol on
either side of the steering wheel.
Tilt Wheel
A tilt steering wheel allows
you to adjust the steering
wheel before you drive.
You can also raise
it to the
highest level to give your
legs more room
when you
exit and enter
the vehicle.
To tilt the wheel, hold the steering wheel and pull the
lever toward
you. Move the steering wheel to a
comfortable position, then release the lever to lock the
wheel
in place.

Anti-Theft Feature
Delco-Loc I1 is a security feature for the compact disc

plays normally. If security system
is used, your player
won’t be usable
if it’s ever stolen, because it won’t turn
on.
The instructions below tell you how to enter your
personal secret code into the system. If your vehicle
loses battery power
for any reason, you must unlock
the system
with the secret code again before the system
will turn on.
Be sure to read through the entire procedure and become
familiar
with the appropriate buttons and knobs before
starting.
1. Write down any &digit number and keep it in a safe
place.
2. Turn the ignition to the ACC or RUN position.

Braking in Emergencies
Use your anti-lock braking system when you need to.
With anti-lock, you can steer and brake at the same
time. In many emergencies, steering can help you more
than even
the very best braking.

Power Steering
If you lose power steering assist because the engine
stops or the system is not functioning, you can steer but
it will take much more effort.
Steering Tips
Driving on Curves
It’s important to take curves at a reasonable speed.
A lot of the “driver lost control” accidents mentioned on
the news happen on curves. Here’s why:
Experienced driver or beginner, each of
us is subject to
the same laws of physics when driving on curves. The
traction of the tires against
the road surface makes it
possible for the vehicle to change its path when you turn
the front wheels. If there’s no traction, inertia will keep
the vehicle going
in the same direction. If you’ve ever
tried to steer a vehicle on wet ice, you’ll understand this. The
traction you can get in
a curve depends on the
condition of your tires and the road surface, the angle at
which the curve is banked, and your speed. While
you’re
in a curve, speed is the one factor you can
control.
Suppose you’re steering through a sharp curve.
Then
you suddenly accelerate. Both control systems --
steering and acceleration -- have to do their work where
the tires meet the road. Unless
you have traction control
and
the system is on, adding the sudden acceleration can
demand too much of those places.
You can lose control.
What should you do if this ever happens? Ease up on the
accelerator pedal, steer the vehicle the way you want it
to go, and slow down.
Speed limit signs near curves warn that you should
adjust your speed. Of course,
the posted speeds are
based on good weather and road conditions. Under less
favorable conditions you’ll want to
go slower.
If you need to reduce your speed
as you approach a
curve, do
it before you enter the curve, while your front
wheels are straight ahead.

3800 Supercharged (L67) Engine
(Option)
Your Park Avenue Ultra has a 3800 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.
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.
Engine Accessory Belt
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.

Power Steering Fluid
How To Check Power Steering Fluid
Unscrew the cap and wipe the dipstick with a clean rag.
Replace the cap and completely tighten it. Then remove
the cap again and look at the fluid level
on the dimtick.
When the engine compartment is hot, the level
should be at the
“HOT” mark.
0 When the engine compartment is cool, the level
should be at the
“FULL COLD” mark.
What to Add
Refer to the Maintenance Schedule to determine what
kind
of fluid to use. See “Recommended Fluids and
Lubricants” in the Index.
NOTICE:
When adding power steering fluid or making a
complete fluid change, always use the proper
fluid. Failure to use the proper fluid can cause
leaks and damage hoses and seals.

Section C: Periodic Maintenance
Inspections
Listed below are inspections and services which should
be performed at least twice a year (for instance, each
spring and fall). You should let your GM dealer’s
service department or other qualified service center
do
these jobs. Make sure any necessary repairs are
completed at once.
INSPECTION
OR SERVICE
Restraint System
WHAT SHOULD BE DONE
Now and then, make sure all your belts,
buckles, latch plates, retractors,
anchorages and reminder systems are
working properly. Look for any loose
parts or damage. If you see anything
that might keep a restraint system from
doing its job, have it repaired.
I
INSPECTION
OR SERVICE I WHAT SHOULD BE DONE I
Steering, Suspen-
sion and Front-
Wheel-Drive Axle Boot and Seal In-
spection Inspect the
front and rear suspension
and steering system for damaged, loose
or missing parts, signs of wear, or lack
of lubrication. Inspect the power steer-
ing lines and hoses for proper hookup,
binding, leaks, cracks, chafing, etc.
Clean and then inspect the drive axle
boot seals
for damage, tears or leakage.
Replace seals if necessary.
Exhaust System
Inspection Inspect
the complete exhaust system.
Inspect the body near the exhaust
system. Look for broken, damaged,
missing or out-of-position parts as
well
as open seams, holes, loose
connections, or other conditions which
could cause a heat build-up in the floor
pan or could let exhaust fumes into the
vehicle. See “Engine Exhaust” in the
Index.
Throttle Linkage Inspect the throttle linkage for
Inspection interference or binding, and for
damaged or missing parts. Replace
parts as needed.
