Total Weight on Your Vehicle’s Tires
Be sure your vehicle’s tires are inflated to the limit for
cold tires. You’ll find these numbers on the Certification
label at the rear edge
of the driver’s doqr (or see “Tire
Loading” in the Index). Then be sure you don’t go over
the
GVW limit for your vehicle.
Hitches
It’s important to have the correct hitch equipment.
Crosswinds, large trucks going by, and rough roads are
a
few reasons why you’ll need the right hitch. Here are
some rules to follow:
0
0
If you’ll be pulling a trailer that, when loaded, will
weigh more than
2,000 pounds (900 kg), be sure to
use a properly mounted, weight-distributing hitch
and sway control of the proper size. This equipment
is very important for proper vehicle loading and
good handling when you’re driving.
Will you have to make any holes in the body of your
vehicle when you install
a trailer hitch? If you do,
then be sure to seal the holes later when you remove
the hitch. If you don’t seal them, deadly carbon
monoxide (CO) from your exhaust can get into your
vehicle (see “Carbon Monoxide” in the Index). Dirt
and water can, too.
The bumpers on your vehicle are not intended for
hitches.
Do not attach rental hitches or other
bumper-type hitches to them. Use only a
frame-mounted hitch that does not attach to the
bumper.
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
If your trailer weighs more than 1,000 pounds (450 kg)
loaded, then it needs its own brakes
- and they must be
adequate. 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.
If you do, both brake systems won’t work well,
or at all.

Towing Your Car
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.
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.
Before you do anything, turn on the hazard warning
flashers.
When you call, tell.the towing service:
That your vehicle has rear-wheel drive.
The make, model, and year of- your vehicle.
Whether you can still move the shift lever.
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.

When to Check: Check your tires once .a month or
more.
Don’t forget
your compact spare-tire (if SO equipped). It
should be at 60 psi (420 Pa).
How to 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.
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.

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 nu-mber will be followed. by a “MS”
(for mad 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.
‘t
A CAUTION:
Mixing tires could cause you to lose control
while driving. If you mix tires of different siz
or types (radial and bias-belted tires), the
vehicle may not handle properly, and you
cows
have a crash. Be sure to use the same size and
type tires
on all four wheels.

you have one). It

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 govement test course. For
