To Use the Engine Coolant  Heater 
1.  Turn off the engine. 
2. Open the hood and unwrap the  electrical  cord.  The 
cord  is  attached to the underside 
of the diagonal 
brace  located behind  the  air cleaner. 
3. Plug it  into  a  normal,  grounded 1 10-volt AC outlet. 
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  AC  outlet. 
If the  cord  won’t  reach,  use a 
heavy-duty  three-prong  extension 
cord rated  for 
at  least 
15 amps. 
4. Before starting  the engine,  be  sure  to unplug 
and store the cord 
as it was before  to keep  it away 
from moving  engine parts. 
If you don’t, it could 
be  damaged. 
How  long should 
you keep  the coolant heater plugged 
in?  The  answer depends 
on the outside  temperature, the 
kind of oil you have, and some other things. Instead of 
trying to  list everything  here,  we ask that you contact 
your dealer in the area  where you’ll be parking your 
vehicle.  The dealer  can give 
you the best  advice  for  that 
particular  area.

Battery  Rundown  Protection 
Your vehicle has a feature  to  help  prevent you from 
draining the battery in case you accidentally leave  the 
interior courtesy lamps, reading/map  lamps,  visor vanity 
lamps,  trunk lamp,  underhood lamp  or  glove box lamps 
on. 
If you  leave  any of these lamps on, they will 
automatically  turn 
off after 20 minutes, if the ignition  is 
in 
OFF. The lamps  won’t come back on again until you: 
Turn the ignition  on, 
0 Turn the lamp switch off, then on; or 
Open a door. 
Note that  if your vehicle has  less than 
15 miles (25 km) 
on the odometer, 
the battery  saver will turn off the lamps 
after only three minutes. 
Retained Accessory Power 
With  retained accessory power, your power windows, 
audio  system and sunroof will  continue  to work up to 
10 
minutes after the ignition key is turned to OFF and none 
of the doors  are opened.

2. 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 vehicle, and the bad grounding  could 
damage the electrical  systems. 
To avoid the possibility of the vehicles rolling, set 
the parking brake firmly on both vehicles involved  in 
the  jump 
start procedure. Put your automatic 
transaxle  in 
PARK (P) before setting the 
parking brake. 
3. Turn off the ignition  on both vehicles. Unplug 
unnecessary accessories plugged into the cigarette 
lighter 
or accessory power outlet.  Turn off all lamps 
that  aren’t  needed as well 
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.  (Your 
vehicle’s battery is located toward the  front 
of the 
passenger’s side 
of the vehicle’s  engine, underneath 
a  diagonal  brace.) 
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.

Engine  Overheating 
You will find a coolant  temperature  gage and a hot 
engine  warning  light on 
your instrument  panel. See 
“Engine Coolant Temperature Gage” and “Engine 
Coolant Temperature Warning  Light”  in  the  Index. 
You 
also have a low coolant  light  on your instrument  panel. 
See “Low Coolant  Light” in the Index. 
If Steam Is Coming  From 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  you 
open  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. 
I 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.

If No Steam Is Coming From Your Engine 
If  you get the  overheat warning but  see  or  hear no 
steam, the problem  may not be too  serious. Sometimes 
the  engine  can get  a little too hot when you: 
Climb  a long  hill on a hot day. 
Stop  after high-speed  driving. 
0 Idle  for  long periods in traffic. 
Tow  a trailer. 
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  NEUTRAL (N); 
otherwise, shift  to the highest gear while 
driving 
-- AUTOMATIC OVERDRIVE (a). 
If  you  no longer  have the overheat warning,  you 
can  drive.  Just to  be safe,  drive  slower  for about 
10 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 und 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.

At a minimum, the  gasoline you use should meet 
specifications  ASTM 
D4814 in the United States and 
CGSB 3.5-M93  in Canada. Improved gasoline 
specifications have  been developed  by the American 
Automobile Manufacturers Association (AAMA)  for 
better  vehicle  performance and  engine protection. 
Gasolines meeting the  AAMA specification  could 
provide  improved driveability and emission control 
system protection compared 
to other gasolines. 
Be  sure  the posted  octane  for premium is at  least 91 (at 
least  89  for  middle grade and 
87 for regular).  If the 
octane  is  less  than 
87, you  may get  a heavy knocking 
noise when  you drive. 
If it’s bad enough,  it can damage 
your  engine. 
If  your vehicle is certified to meet California Emission 
Standards  (indicated on the underhood  emission control 
label),  it  is designed 
to operate on fuels  that meet 
California specifications.  If such 
fuels are  not  available 
in states adopting California  emissions standards, your 
vehicle will  operate satisfactorily 
on fuels meeting 
federal specifications, but  emission control system  performance 
may  be affected.  The malfunction  indicator 
lamp on your instrument panel  may turn on and/or your 
vehicle  may fail a smog-check test.  If this occurs, return 
to your authorized Buick dealer  for diagnosis  to 
determine the  cause of failure.  In the event  it  is 
determined that the  cause of the condition is the type 
of 
fuels used,  repairs  may  not  be  covered by your warranty. 
Some  gasolines that  are not reformulated for low 
emissions contain an  octane-enhancing additive called 
methylcyclopentadienyl manganese tricarbonyl (MMT); 
ask your service station operator whether  or not  his fuel 
contains  MMT. General Motors does 
not recommend the 
use  of such gasolines. 
If fuels  containing  MMT are used, 
spark plug  life may  be reduced and your emission 
control system performance  may be affected. The 
malfunction indicator lamp  on your instrument panel 
may  turn on. If this occurs, return  to your authorized 
Buick dealer  for service.

Filling a Portable Fuel Container  Checking Things 
Under  the Hood 
Never  fill a portable fuel container  while it is in 
your  vehicle.  Static electricity  discharge  from the 
container  can  ignite  the gasoline  vapor.  You can 
be  badly  burned and your  vehicle  damaged 
if this 
occurs.  To help  avoid  injury to you  and others: 
0 Dispense  gasoline  only  into approved 
containers. 
0 Do  not  fill  a  container  while it is  inside a 
vehicle,  in  a  vehicle's  trunk, pickup  bed  or 
on  any  surface other  than the ground.

Things that  burn  can  get  on  hot engine  parts and 
start  a  fire.  These  include  liquids  like  gasoline, 
oil,  coolant,  brake fluid,  windshield  washer  and 
other  fluids,  and plastic  or rubber.  You or others 
could  be  burned. Be careful  not  to drop or spill 
things  that will burn  onto a hot  engine.
