Try not to pass more than one vehicle at a time on
two-lane roads. Reconsider before passing the next
vehicle.
Don’t overtake a slowly moving vehicle too rapidly.
Even though the brake lights are not flashing, it may
be slowing down or starting to turn.
If you’re being passed, make it easy for the
following driver to get ahead of you. Perhaps you
can ease a.little to the right.
Loss of Control
Let’s review what driving experts say about what
happens when the three control systems (brakes, steering and acceleration) don’t have enough friction where the
tires meet the road to do what the driver has asked.
In any emergency, don’t give up. Keep trying to steer
and constantly seek an escape route or area of less
danger.
Skidding
In a skid, a driver can lose control of the vehicle.
Defensive drivers avoid most skids by taking reasonable
care suited to existing conditions, and by not
“overdriving” those conditions. But skids are always
possible. The three types
of skids correspond
to your Buick’s
three control systems. In the braking skid your wheels
aren’t rolling.
In the steering or cornering skid, too
much speed or steering in a curve causes tires to slip and
lose cornering force. And in the acceleration skid too
much throttle causes the driving wheels to spin.
A cornering skid and an acceleration skid are best
handled by easing your foot off the accelerator pedal.
If your vehicle starts to slide (as when you- turn a corner
on a wet, snow- or ice-covered road), ease your foot
off
the accelerator pedal as soon as you feel the vehicle start
to slide. Quickly steer the way you want the vehicle to
go. If you start steering quickly enough, your vehicle
will straighten out. As it does, straighten the front
wheels.
Of course, traction is reduced when water, snow, ice,
gravel, or other material is on the road. For safety, you’l\
l
..
want to slow down and adjust your driving to these
conditions. It is important to slow down on slippery
surfaces because stopping distance will be longer and
vehicle control more limited.
While driving on a surface with reduced traction, try
your best to avoid sudden steering, acceleration, or
braking (including engine braking by shifting to a lower gear). Any sudden changes could cause the tires to slide.
You may not realize the surface is slippery until your
I

The bumpers on your vehicle are not intended for
hitches.
Do not attach rental hitches or other
bumper-type hitches to them.
Safety Chains
You should always attach chains between your vehicle
and. your trailer. Cross the safety chains under the
tongue of the trailer
so that the tongue will not drop to
the road if it becomes separated from the hitch.
Instructions about safety chains may be provided by the
hitch manufacturer or by the trailer manufacturer.
Follow the manufacturer’s recommendation for
attaching safety chains. Always leave just enough slack
so you can turn with your rig. And, never allow safety
chains to drag
on the ground.
Trailer Brakes
Does your trailer have its own brakes? Be sure to read
and follow the instructions for the trailer brakes
so
you’ll be able to install, adjust and maintain them
properly. Because you have anti-lock brakes, do not try
to tap into your vehicle’s brake system. ff you do, both
brake systems won’t work well, or at all.
Driving with a Trailer
Towing a trailer requires a certain amount of experience.
Before setting out for the open road, you’ll want to get
to know your rig. Acquaint yourself with the feel of
handling and braking with the added weight of the
trailer. And always keep in mind that the vehicle you are
driving is now a good deal longer and not.nearly
so
responsive as your vehicle is by itself.
Before you start, check the trailer hitch and platform,
safety chains, electrical connector, lights, tires and
mirror adjustment. If the trailer has electric brakes, start
your vehicle and trailer moving and then apply the
trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection
at the same time.
During your trip, check occasionally to be sure that the
load
is secure, and that the lights and any trailer brakes
are still working.
Following Distance
Stay at least twice as far behind the vehicle ahead as you
would when driving your vehicle without a trailer. This
can help you avoid situations that require heavy braking
and sudden turns.

Towing Your Buick
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. Before you do anything, turn on the hazard warning
flashers.
When you call, tell the towing service: That your vehicle has front-wheel drive.
0 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 wan.t to
see them.
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.

When to Check: Check your tires once a month or
more.
Don’t forget your compact spare tire. It should be at
60
psi (420 Pa).
How tco Check: Use a good quality pocket-type gage to
check tire pressure. Simply looking at the tires will not
tell you the pressure, especially if
you have radial tires --
which may look~properly inflated even if they’re
underinflated. 1
If your tires have valve caps, be sure to put them back
on. They help prevent leaks~ by keeping out dirt and
moisture.
Tire Inspection and Rotation
To make your tires last longer, have them, inspected and
rotated at the mileages recommended in the
Maintenance Schedule. See “Scheduled Maintenance
Services” in the Index. Use this rotation pattern.
After the tires have been rotated, adjust the
front and
rear inflation pressure as shown on the Tire-Loading
Information label. Make certain that all wheel nuts are
properly tightened. See “Wheel Nut Torque” in the
Index.

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.
A CAUTION:
Mixing tires could cause you to lose control
while driving.
If you mix tires of different sizes or
types (radial and bias-belted tires), the vehicle
may not handle properly, and you could have a
crash. Be sure to use the same size and type
tires on all wheels.
It’s all right to drive with your compact spare,
though. It was developed for limited use on your
vehicle.

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
245

(1 112) times as well on the government course as a tire
graded
100. The relative performance of tires depends
upon the actual conditions of their use, however, and
may depart significantly from the norm due to variations
in driving habits, service practices.and differences in
road characteristics and climate.
’Ikaction - A, B, C
The traction grades, from highest to lowest are: A, B,
and C. They represent the tire’s.ability to stop on wet
pavement
as measured under controlled conditions on
specified government test surfaces
of asphalt and
concrete. A tire marked
C may have poor traction
performance.
Warning: The traction grade assigned to this tire is based on braking (straight-ahead) traction tests and does not
include cornering (turning) traction.
Temperature - A, B, C
The temperature grades are A (the highest), B, and C,
representing the tire’s resistance to the generation of
heat and its ability to dissipate heat when tested under controlled conditions on a- specified indoor laboratory
test wheel. Sustained high temperature can cause the
material of the tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire failure. The
grade
C corresponds to a level of performance
Federal Motor Vehicle Safety Standard
No. 109. Grades
B and A represent higher levels of performance on the
laboratory test wheel than the minimum required by law.
Warning: The temperature grade for this tire is
established for a tire that is properly inflated and not
overloaded. Excessive speed, underinflation, or
excessive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
Those grades are molded on the sidewalls of passenger
car tires.
While the tires available as standard or optional
equipment on General Motors vehicles may vary with
respect to these grades, all such tires meet General
Motors performance standards and have been approved
for use on General Motors vehicles. All passenger type
(P Metric) tires must conform to Federal safety
requirements in addition to these grades.
Wheel Alignment and Tire Balance
The wheels on your vehicle were aligned and balanced
carefully at the factory to give you the longest tire life
and best overall performance.

1 e Use solvent-type cleaners in a well-ventilated area
only.
If you use them, don’t saturate the stained area.
If a ring forms after spot cleaning, clean the entire
area immediately or it will
set.
Using Foam-Type Cleaner on Fabric I
0 Vacuum and brush the area to remove any loose dirt.
0 Always clean a whole trim panel or section. Mask ’
surrounding trim along stitch or welt lines.
Mix Multi-Purpose Powdered Cleaner following the
directions on the container label.
0 Use suds only and apply with a clean sponge.
0 Don’t saturate the material.
Don’t rub it roughly.
As soon as you’ve cleaned the section, use a sponge
to remove the suds.
0 Rinse the section with a clean, wet sponge.
0 Wipe off what’s left with a slightly damp paper towel
or cloth.
0 Then dry it immediately with an air hose, a hair
dryer or a heat lamp.
1
0 Wipe *with a clean cloth.
Using Solvent-Type Cleaner on
Fabric
First, see if you have to use solvent-type cleaner at all.
Some spots and stains will clean
off better with just
water and mild soap.
If
you need to use it, then:
Gently scrape excess soil from the trim material with
a clean, dull knife or scraper. Use very little cleaner,
light pressure and clean cloths (preferably cheesecloth). Cleaning should start at the outside of
the stain, “feathering” toward the center. Keep
changing to a clean section of the cloth.
When you clean a stain from fabric, immediately dry
the area with an air hose, hair dryer, or heat lamp to
help prevent a cleaning ring. (See the previous
