Snow can trap exhaust gases under your vehicle.
This can cause deadly CO (carbon monoxide) gas
to get inside. CO could overcome you and kill
you. You can’t see !it or smell it,
so you might not
know it
is in your vehicle. Clear away snow from
around the base of your vehicle, especially any
that is blocking ‘your exhaust pipe. And check
around again from time
to time to be sure snow
doesn’t collect there.
Open a window just a little on the side of the
vehicle that’s away from the wind.
This will help
keep
CO out.
Run your erigine only as long as you must. This saves
fuel. When you run the engine, make it go a little faster
than just idle. That is, push the accelerator slightly.
This
uses less fuel for the heat that you get and it keeps the
battery charged. You will need a well-charged battery
to
restart the vehicle, and possibly for signaling later on
with your headlamps. Let the heater run for awhile.
Then, shut the engine
off and close the window almost
all the way to preserve the heat. Start the engine again
and repeat this
only when you feel really uncomfortable
from the cold. But
do it as little as possible. Preserve the
fuel as long as you can.
To help keep warm, you can get
out of the vehicle and do some fairly vigorous exercises
every half hour
or so until help comes.

2.
3.
Get the vehicles close enough so the jumper cables
can reach, but be sure the vehicles aren’t touching
each other.
If they are, it could cause a ground
connection you don’t want. You wouldn’t be able to
start your Buick, and the bad grounding could
damage the electrical systems.
Turn
off the ignition on both vehicles. Unplug
unnecessary accessories plugged into the cigarette
lighter. Turn
off all lamps that aren’t needed as well
as as radios. This will avoid sparks and help save
both batteries. In addition, it could save your radio!
NOTICE:
If you leave your radio on, it could be badly
damaged. The repairs wouldn’t be covered by
your warranty.
4. Open the hoods and locate the batteries.
Find the positive
(+) and negative (-) terminals on
each battery.
A
I CAUTION:
An electric fan can start up even when the engine
is not running and can injure you. Keep hands, clothing and tools away from any underhood
electric fan.

Using a match near a battery can cause battery
gas to explode. People have been hurt doing this,
and some have been blinded. Use a flashlight if
you need more light.
Be sure the battery has enough water. You don’t
need
to add water to the Delco Freedom@ battery
installed in every new
GM vehicle. But if a
battery has filler caps, be sure the right amount
of fluid is there. If it is low, add water to take
care of that
first. If you don’t, explosive gas
could be present.
Battery fluid contains acid that can burn you.
Don’t get
it on you. If you accidentally get it in
your eyes or on your skin, flush the place with
water and get medical help immediately.
5. Check that the jumper cables don’t have loose or
missing insulation.
If they do, you could get a shock.
The vehicles could be damaged, too.
Before you connect the cables, here are some basic
things you should know. Positive
(+) will go to
positive
(+) and negative (-) will go to negative (-)
or a metal engine part. Don’t connect positive (+) to
negative (-) or you’ll get a short that would damage
the battery and maybe other parts, too.
Fans or other moving engine parts can injure you
badly. Keep your hands away from moving parts
once the engines are running.

Engine Overheating
You will find a coolant temperature gage or the
warning light about a hot engine on
your Buick’s
instrument panel.
If St1 .-m Is 1 - - ng Fro Your Engine
Steam from an overheated engine can burn you
badly, even if you just open the hood. Stay away
from the engine if you see or hear steam coming
from it. Just turn
it off and get everyone away
from the vehicle until
it cools down. Wait until
there is no sign of steam or coolant before
opening the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch fire. You or
others could be badly burned. Stop your engine if
it overheats, and get out of the vehicle until the
engine is cool.
NOTICE:
If your engine catches fire because you keep
driving with no coolant, your vehicle can be
badly damaged. The costly repairs would not be
covered by your warranty.

I NOTICE:
Spinning your wheels can destroy parts of your
vehicle
as well as the tires. If you spin the wheels
too fast while shifting your transaxle back and
forth, you can destroy your transaxle.
For information about using tire chains on your vehicle,
see “Tire Chains’’ in the Index.
Rocking your vehicle to get it out:
First, turn your steering wheel left and right. That will
clear
the area around your front wheels. Then shift back
and forth between REVERSE
(R) and a forward gear,
spinning the wheels
as little as possible. Release the
accelerator pedal while you shift, and press lightly
on
the accelerator pedal when the transaxle is in gear. If
that doesn’t get you
out after a few tries, you may need
to be towed out.
If you do need to be towed out, see
“Towing Your Vehicle” in the Index.

Engine Coolant
@ Protect ag- rust and corrosion.
@ Help.keep the proper engine temperature.
Let the whg lightd md gages work as
they shouicl.
NOTICE:
When adding coolant it is important that you use
DEX-COOL TM (orange-colored, silicate-free)
coolant meeting
GM Specification 6277M.
If silicated coolant is added to the system,
premature engine, heater core or radiator
corrosion may result. In addition, the engiue
coolant will
require change sooner -- at
30,000 miles (50 000 km) or 24 months,
whichever occurs first.

Brakes
Bra
Your brake master cylinder reservoir is here. It is filled
with
DOT-3 brake fluid.
There are
only two reasons why the brake fluid level in the
reservoir might go down. The first is that the brake fluid
goes down to an acceptable level during normal brake
lining wear. When new linings are put in, the fluid level goes
back up. The other reason is that fluid is leaking out
of the brake system. If it is, you should have your brake
system fixed, since a leak means that sooner or later your
brakes won’t work well, or won’t work at all.
So, it isn’t a good idea to “top off’ your brake fluid.
Adding brake fluid won’t correct a leak.
If you add fluid
when your linings are worn, then you’ll have too much
fluid when you get new brake linings.
You should add
(or remove) brake fluid,
as necessary, only when work is
done on the brake hydraulic system.
If you have too much brake fluid, it can spill on the
engine. The fluid
will burn if the engine is hot
enough. You or others could be burned, and your
vehicle could be damaged. Add brake fluid
only
when work is done on the brake hydraulic system.
When your brake fluid falls to a low level, your brake
warning light will come on.
See “Brake System Warning
Light”
in the Index.

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).
A CAUTION:
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.
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.
Fre’- -1ovement
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.
