1996 BUICK PARK AVENUE service indicator

Voltage Indicator (Option)
If you have the optional
gage cluster, this gage
shows voltage in the
electrical system. The
8
normal range is I 1 to
18 15 volts.
W
If the reading stays outside the normal range, or the
battery warning light comes on, have your Buick dealer
check the electrical system.
Brake System Warning Light
If the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
This light should come
on
when you turn the ignition
key to
START. If it doesn’t
come on then, have it fixed
so it will be ready to warn
you if there’s a problem.
If the light and chime come on while you are driving,
pull off the road and stop carefully. You may notice that
the pedal is harder to push. Or, the pedal may go closer
to the floor. It may take longer
to stop. If the light is still
on, have the vehicle towed for service. (See “Towing
Your Vehicle” in the Index.)

Low Coolant Warning Light
COOLANT
LOW
When this light comes on,
the cooling system is
low on
coolant. As a bulb check, it
will come on when the
ignition in the
RUN
position and then go off.
Malfunction Indicator Lamp
(Check Engine Light)
CHECK
Your Buick is equipped
with a computer which
monitors operation
of the
fuel, ignition and emission
control systems.
If the coolant level is low, the light will come back on. If
this happens, see “Engine Coolant” in the Index for
proper cooling system fill.
After the coolant level
is returned to its proper level, the
LOW COOLANT light will go off after
20 seconds or
remain
off on the next ignition cycle. This system
is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended
to assure that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment. (In Canada, OBD I1 is replaced by
Enhanced Diagnostics.) The CHECK ENGINE light
comes on to indicate that there is a problem and service
is required. Malfunctions often will be indicated by the
system before any problem is apparent, which may
prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.

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 don’t have the 3800 Supercharged engine (VIN
Code l), use regular unleaded gasoline rated at 87 octane
or higher.
If you have the 3800 Supercharged engine, use premium
unleaded gasoline rated at 91 octane or higher.
At a minimum, the gasoline you use should meet
specifications ASTM D4814 in the United States and
CGSB 3.5-M93 in Canada. Improved gasoline
specifications have- been developed by the American
Automobile Manufacturers Association (AAMA) for
’ better vehicle performance and engine protection.
Gasolines meeting ihe AAMA specification could
, ’ provide improved driveability and emission control
system protection compared to other gasolines.
Be sure the posted octane for premium is at least 91
(at least 89 for middle grade and
87 for regular). If the
i octane is, less than 87, you may get a heavy knocking
noise when you drive.
If it’s bad enough, it can damage
your engine.
,
If you have the 3800 Supercharged engine, in an
emergency, you may be able to use .a lower octane
-- as
low as 87
-- if heavy knocking does not occur. If you
are using 91 or higher octane unleaded gasoline and you
still heq heavy knocking, your engine needs service.
,
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.
If your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label), it
is designed to operate’on fuels that meet California
specifications. If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may turn on and/or your vehicle
may fail a smog-check test.
If this occurs, return to your
authorized Buick dealer for diagnosis to determine,the
cause of failure.
In the event it is determined that the
cause of the condition is the type of
fuels used, repairs
may not be covered by your warranty.

In Canada, some gasolines contain an octane-enhancing
additive called
MMT. If you use such fuels, your
emission control system performance may deteriorate
and the malfunction indicator lamp on your instrument
panel may turn on. If this happens, return to your
authorized Buick dealer for service.
To provide cleaner air, all gasolines are now required to
contain additives that will help prevent deposits from
forming in your engine and fuel system, allowing your
emission control system to function properly. Therefore,
you should not have to add anything to the fuel. In
addition, gasolines containing oxygenates, such as ethers
and ethanol, and reformulated gasolines may be
available in your area to help clean the air. General
Motors recommends that
you use these gasolines if they
comply with the specifications described earlier.
I NOTICE:
Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t be covered under your warranty.
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline or any other fuel not
recommended in the previous text
on fuel. Costly repairs
caused by use
of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company that does business in the
country where you’ll be driving.
You can also write us at the following address for
advice. Just tell
us where you’re going and give your
Vehicle Identification Number (VIN).

Brake Wear
Your Buick has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and
go
or be heard all the time your vehicle is moving (except
when you are pushing on the brake pedal firmly).
The brake wear warning sound means that sooner
or later your brakes won’t work well. That could
lead to an accident. When
you hear the brake
wear warning sound, have your vehicle serviced.
I NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something
is wrong with
your brakes.
Free movement of brake calipers and properly torqued
wheel nuts are necessary
to help prevent brake
pulsation. When tires are rotated, inspect brake calipers
for movement, brake pads for wear, and evenly torque
wheel nuts in the proper sequence to
GM specifications.
Your rear drum brakes don’t have wear indicators, but
if
you ever hear a rear brake rubbing noise, have the rear
brake linings inspected. Also, the rear brake drums
should be removed and inspected each time the tires
are
removed for rotation or changing. When you have the
front brakes replaced, have the rear brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.
Brake Pedal Travel
See your dealer if the brake pedal does not return to
normal height, or if there is a rapid increase
in pedal
travel. This could be a sign of brake trouble.
Brake Adjustment
Every time you apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.

0 The tire has a bump, bulge or split.
0 The tire has a puncture, cut or other darnage that
can’t be repaired well because of the size or location
of the damage. 7 One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires have
only
1/16 inch (1.6 mm) or
less of tread remaining.
You need a new tire if any of the following statements
are true:
0 You can see the indicators at three or more places
around the
tire.
0 You can see cord or fabric showing through the
tire’s rubber.
The tread or sidewall is cracked, cut or snagged deep
enough to show cord
or fabric.
uying New Til
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 an
“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.
