There’s something else about drinking and driving that
many people don’t know. Medical research shows that
alcohol in a person’s system can make crash injuries worse. That’s especially true for brain, spinal cord and
heart injuries. That means that
if anyone who has been
drinking
- driver or passenger - is in a crash, the
chance of being killed or permanently disabled is higher
than
if that person had not been drinking. And we’ve
already-seen that the chance
of a crash itself is higher for
drinking drivers.

/q CAUTION:
Drinking and then driving is very dangerous.
Your reflexes, perceptions, and judgment
will be
affected by even a small amount
04 alcohol. You
could have a serious - or even fatall - accident
if you drive after drinking. Please don’t drink
and drive or ride with a driver who has been
drinking. Ride home
in a cab; or if you’re with a
group, designate a driver who will not drink.
Control of a Vehicle
You have three systems that make your vehicle go where
you want it to
go. They are the brakes, the steering and
the accelerator. All three systems have to
do their work
at the places where the tires meet the road.
Sometimes, as
when you’re driving on snow or ice, it’s
easy to ask more of those control systems than the tires
and road
can provide. That means you can lose control
of your vehicle.

If your brake pedal goes down farther man normal, your
rear drum brakes may need adjustment. Adjust them by
backing
up and firmly applying the brakes a few times.

Braking in Emergencies I
Use your anti-lock braking sysKem 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.
Steering
Power Steering
If you lose power steering a ssist becau Lse
the engine
stops or the system fails to function, 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 driviqg on curves. The
traction
of the tires agairist the road s.urface makes it

Hydroplaning Some Other Rainy Weather Tips
Hydroplaning is dangerous. So much water can build up
under your tires that they can actually ride
on the water.
This can happen if the road is wet enough and you’re
going fast enough. When your vehicle’ is hydroplaning,
it has little or no contact with the road.
You might not be aware of hydroplaning. You. could
drive along for some time without realizing your tires
aren’t in constant- contact with the road. You could find
out the hard way: when you have to slow, turn, move out
to pass - or if y-ou get hit by a gust of wind. You could
suddenly find yourself out of control.
Hydroplaning doe.sn’t happen. often. But it can if your
tires haven’t much tread
or if the pressure in one or
more is low.
It- can happen if a lot of water is standing
on the road. If you can see reflections from trees,
telephone poles, or other vehicles, and raindrops
a
“dimple” the water’s surface, there could-be
hydroplaning.
Hydroplaning usually happens at higher speeds. There
just isn’t a hard and fast rule about hydroplaning. The
best advice is to slow down when it is raining, and be
careful.

PBrkiBg .. Hi&$ You can turn your front wheels to keep your vehicle
from rolling downhill or out into traffic.
Here’s how:
.,
Parking Downhill
Turn your wheels to the right.
You don’t have to jam your tires against the curb, if
there is a curb. A gentle contact is all you need.

Winter Driving
Here are some tips for winter driving:
Have your Buick in good shape for winter. Be sure
your engine coolant mix is co-rrect.
Snow tires. can help in loose snow, but they may give
you less traction on ice than regular tires. If you do
not expect to be driving
in deep snow, but may have
to travel over ice,
you may not want to switch to
snow tires at all.
You may want to put winter emergency supplies in
your vehicle.
I
I
.. . ..
Include an.ice:scrapGq a small brush .or broom, a supply
of'windshield washer fluid,
a rag, some winter outer
clothing,
a small shovel, a flashlight, a, red. cloth,. and a
couple
.of reflective warning triangles. And, if you will
be driving under:severe conditions, include a small bag
of sand, a piece of ,old carpel .or a couple of burlap. bags
to help provide traction. Be sure y.ou properly secure
these items in your vehicle.

D.riving on Snow or Ice What’s the worst time for this? “Wet ice.” Very cold
snow or ice c.an be slick and hard to drive
on, But wet
ice can be even more’trouble because it may offer
the.
leait traction of all. You can get “wet ice” when’ it’s , ’
about freezing (3ZoF..O0C) and freezing rain begins to
fail. Try to avoid driving on we1 ice until salt and sand
crews can get there.
,.
Whatever the conditio,n - smooth ice, packed, blowing
or loose. snow
.- drive with caution. Accelerate gently.
Try .not
to break the fragile traction. If you accelerate,,
too fast, the drive wheels will spin and polish the surface
under the tires even more.
Your anti-lock brakes improve your ability to make. a
hard stop on a slippery road. Even though you have the
anti-lock braking system, you’ll want to begin-stopping
sooner than you would on dry pavement. See “Anti-lock” in the Index.
Allow greater following distance on any slippery
road.

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.

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 biakes, start
your yehicle 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 turris.
.
Passing
You’ll need. more passing distance up ahead when
you’re towing a trailer. And, because you’re a good deal \
longer, you’ll need to go much farther beyond the
.
passed vehicle before you can return to your lane.
Backing Up
Hold the bottom of the steering wheel with one hand.
Then, to move the trailer
to the left, just move that hand
to the left.
To mo.ve the trailer to the right, move your
hand to the right. Always back up slowly and, if
possible, have someone guide
you.
Making Turns
When you’re turning with a trailer, make wider turns
than normal.
Do this so your trailer won’t strike soft
shoulders, curbs, road signs, trees, or other objects.
Avoid jerky or sudden maneuvers. Signal well in
advance.
Turn Signals When Towing a Trailer
When you tow a trailer, your vehicle has to have .a
different turn signal flasher and extra wiring. The green
arrows on your instrument panel will
flash whenever
you signal a
turn or lane change. Properly hooked up,
199

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.

Compact Spare T,ire
Although the compact spare was fully inflated when
your vehicle -was new, it can lose air after a time. Check
the inflation pressure regularly. It should be
60 psi (420
Pa). The compact spare is made to g6 up to 3,000 miles
(50,OO km), so you can finish your trip and have. your
full-size tire repaired
or replaced where you want. Of
course, it’s best to replace your spare with a full-size ti\
re
as soon as you can. Your spare will last longer and be in
good shape in case you need it again.
Your anti-1ock.brake system warning light -may come on
when you are driving with a compact spare. See
“Anti-Lock Brake System Waming Light”
in the Index.
Don’t-use
your compact spare on some other vehicle. And don’t mix your compact spare or wheel
with other
wheels or tires. They. won’t
fit.. Keep your spare and its
wheel together.
