Engine Block Heater (Canada Only)
In very cold weather, 0 " F (- 18 "C) or colder, the engine
block heater can help. You'll get easier starting and
better fuel economy during engine warm-up.
To use the block heater:
1. Turn off the engine.
2. Open the hood and unwrap the electrical cord.
3. Plug it into a normal, grounded 110-volt outlet.
ProCarManuals.com

A CAUTION:
I
Plugging the cord into an ungrounded outlet
could cause an electrical shock.
Also, the wrong
kind of extension cord could overheat and cause
a fire. You could be seriously injured. Plug the
cord into a properly grounded three-prong
110-volt outlet. If the cord won’t reach, use
a
heavy-duty three-prong extension cord rated for
at least
15 amps.
I
I NOTICE:
After you’ve used the block heater, be sure to
store the cord as
it was before, to keep it away
from moving engine parts. If you
don’t, it could
be damaged.

I
How long should you keep the block heater plugged in?
The answer depends on the weather, the kind
of oil you
have, and some other things. Instead
of trying to list
everything here, we ask that
you contact a Buick dealer
in the area where you’ll be parking your vehicle. The dealer
can give you the
best advice for that particular
area.

Defrost Rear Window Defogger
This setting will direct most
of the air flow toward the
windshield. Use
DEFROST
when there is fog or ice on
the-windshield.
Defrost will work better if any ice and snow is cleared
from the hood and the air inlet area between the hood
and the windshield.
Blower speed will be controlled automatically, but
you
can choose another speed by pushing the HI or LO
buttons. The
lines
you see on the
rear window will warm the
glass. Press the button to
start warming your
window.
After
10 minutes, it will go
off by itself, or pressing the
button again during the
heating cycle will shut it
off. If you need additional
warming time, push the
button again.
c. i
If you have the heated outside rearview mirror option,
the mirror will be warmed when the rear defogger is on.

ProCarManuals.com

The Bi-level setting directs outside air into your vehicle
in two ways. Cool air is directed toward your upper
body through instrument panel outlets, while slightly
warmed air is directed through the heater outlet at your
feet.
The air conditioner compress& operates in all Air
Conditioning positions and the Defrost position when
the outside temperature is above
48 OF (9 “C).
When you don’t need to cool the outside air, use the
VENT, HEAT and
DEFROST settings. Adjust the
temperature control for comfort. You’ll get better fuel
economy (gas mileage) if you’re not cooling the outside
air. When you cool the air, your engine runs a
refrigeration compressor, and it has to work harder.
Vent
For mild outside temperature, when little heating or
cooling is needed, use the
VENT setting. Air will flow
thought the instrument panel outlets. Use the air outlets
to turn on, adjust and turn
off the air flow. Adjust the
temperature lever
to the desired temperature.
Heater
When outside temperatures are cold, pressing the HTR
setting and adjusting the temperature lever will send
warm air through the floor outlets and some through the
defroster vents.
Defrost
The DEFROST setting directs most of the air flow
toward the windshield. Use defrost when you want to
remove
fog or ice from the windshield. When it’s 48OF
(9 * C) or warmer, you’ll get cooled air.
Defog
Air entering the vehicle will be evenly split between the
floor outlets and the outlets near the windshield. You
can control the temperature of the air and the fan speed
to clear the foggy windows.

Rear Window Defogger
The lines you see on the
rear window warm the
glass. Press the button to
start warming your
window. After 10 minutes,
it will
go off by itself, or
pressing the button again
during the heating cycle will shut it off. If
you need
additional warming time,
push the button again.
NOTICE:
Scraping the inside of your rear window could
cut and damage the heater. Your warranty would
not cover this damage. And don’t put decals
there, you might have to scrape them
off.
Audio Systems
Your Delco@ audio system has been designed to operate
easily and give years
of listening pleasure. But you will
get the most enjoyment out
of it if you acquaint yourself
with
it first. Find out what your DelcoB system can do
and how to operate all its controls, to be sure you’re
getting
the most out of the advanced engineering that
went into
it.
FM Stereo
FM stereo will give you the best sound. But FM signals
will reach only about 10 to
40 miles (16 to 65 km). And,
tall buildings or hills can interfere with FM signals,
causing the sound to come and go.
AM
The range for most AM stations 1s greater than for FM,
especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise.

A CAUTION:
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.
CAUTION: (Continued)
LCAUTION:
Run your engine 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 headlights. Let the heater run for awhile.
ProCarManuals.com

If you get the overheat warning with no sign of steam,
try this for a minute or
so:
1. Turn off your air conditioner.
2. Turn on your heater to full hot at the highest fan
speed and open the window as necessary.
3. If you’re in a traffic jam, shift to “N” (Neutral).
If
you no longer have the overheat warning, you can
drive. Just
to be safe, drive slower for about ten minutes.
If the warning doesn’t come back on,
you can drive
normally.
If the warning continues, pull over, stop, and park your
vehicle right away.
If there’s still no sign of steam, you can idle the engine
for two or three minutes while you’re parked, to see if
the warning stops. But then, if
you still have the
warning, TURN
OFF THE ENGINE AND GET
EVERYONE OUT
OF THE VEHICLE until it cools
down. You
may decide not to lift the hood but to get service
help right away.
e

,
When you decide it’s safe to lift the hood, here’s what
you’ll see:
Coolant recovery tank
* Radiator pressure cap
Electric engine fans
ProCarManuals.com

I A CAUTION:
An electric fan under the hood 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.
If the coolant inside the coolant recovery tank is boiling,
don’t do anything else until it cools down.
. .” P
The coolant level should be at or above “FULL COLD.”
If it isn’t, you may have a leak in the radiator hoses,
heater hoses, radiator, water pump
or somewhere else in
the cooling system.
I I
A CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Don’t touch them.
If you
do, you can be burned.
Don’t run the engine
if there is a leak. If you run
the engine, it could lose all coolant. That could
cause an engine fire, and you could be burned.
Get any leak fixed before you drive the vehicle.
I
Engine damage? Il’onl I mning bUrlr engine

If there seems to be no leak, check to see if the electric
engine fans are running. If the engine
is overheating,
both fans should be running. If they aren’t, your vehicle
needs service.

0 SAE low-30
As shown in this chart, SAE 1OW-30 is best for your
vehicle. However, you can use
SAE 5W-30 if it’s
going to be colder than
60 OF (1 6 ” C) before your
next oil change. When it’s very cold, below
0°F
(- 18 ” C), you should use SAE 5W-30.
These numbers on an oil container show
its viscosity, or
thickness. Do not use other viscosity oils such as SAE
low-40 or SAE 20W-50.

to advise if you think
something should be added.

Most trips are through dusty places.
If any one of these is true for your vehicle, then
you
need to change your oil and filter every 3,000 miles
(5 000 km) or 3 months -- whichever comes first. (See
“Change Oil Soon” in the Index.)
If none of them is true, change the oil every 7,500 miles
(12 500 km) or 12 months -- whichever comes first.
Change
the filter at the first oil change and at every
other oil change after that. (See “Change
Oil Soon” in
the Index.)

big help

weather,

this option, see “Engine Block Heater.”
