NOTICE: 
Your engine  is  designed  to work  with the 
electronics in  your vehicle. 
If you add  electrical 
parts  or  accessories,  you  could change the 
way 
the fuel injection system operates.  Before adding 
electrical equipment,  check  with your retailer. 
If 
you  don’t,  your engine might not  perform 
properly. 
If you  ever have to have  your vehicle  towed,  see 
the  part  of this  manual  that tells  how  to do  it 
without damaging your  vehicle.  See  “Towing 
Your  Vehicle’’  in the  Index. 
Driving  Through  Deep Standing 
Water 
NOTICE: 
If you  drive  too quickly  through  deep puddles or 
standing  water, water can come  in through  your 
engine’s  air  intake  and  badly damage your 
engine. 
If you  can’t  avoid  deep puddles or 
standing  water, drive  through  them very slowly. 
Engine  Coolant  Heater (Option) 
In very  cold weather, 0” F (- 18 O C) or colder,  the  engine 
coolant  heater  can  help.  You’ll get  easier  starting  and 
better  fuel  economy  during  engine  warm-up.  Usually, 
the  coolant  heater  should be plugged  in a 
minimum of 
four hours prior to starting  your vehicle. 
2-17  

To use  the  coolant  heater: 
1. Turn off the  engine. 
2. Open  the  hood  and  unwrap  the  electrical  cord. 
3. Plug it into  a  normal,  grounded  1  10-volt  outlet. 
r 
NOTICE: 
After  you’ve  used  the  coolant  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. 
How  long  should  you  keep  the  coolant  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  your 
Oldsmobile  retailer  in  the  area  where  you’ll  be  parking 
your  vehicle.  The  retailer 
can give  you  the best  advice 
for  that  particular  area.

MODE CONTROL: The right control knob changes 
the functions 
of your  system. 
VENT: Use when  outside temperatures are mild,  and 
little heating or cooling  is needed.  Air flow  is through 
the instrument panel outlets. 
Set the center control knob 
to the temperature desired. 
BI-LEV: Use  on cool, but sunny days. This setting 
brings in the outside  air, but directs it  in two ways.  The 
cool air is directed to the upper portion  of your  body 
through the instrument panel outlets,  but slightly 
warmer  air  is directed through  the heater ducts and 
defroster  vents.  At times this temperature difference 
may  be  more apparent than others. 
HEAT This setting brings heated  air through the heater 
ducts,  and some through the windshield defroster  vents. 
If you have the optional engine coolant heater (engine 
block  heater)  and 
use it during cold  weather, 0°F 
(- 1 8’ C) or lower, your heating system  will  more quickly 
provide heat because the  engine coolant  is already 
warmed.  See “Engine Coolant Heater (Engine Block 
Heater)”  in the Index. 
DEFOG: This setting divides  air flow equally between 
the heater ducts and the windshield defroster vents. 
DEF: This setting directs air through the 
windshield defroster vents located on top 
of the 
instrument panel. 
Defogging  Windows 
To defog the windshield, turn all three control knobs  to 
the far right.

Air  Conditioning  System  (Option) 
The  air  conditioner and heater  work best  if you keep 
your  windows  closed  while  using them.  Your vehicle 
also  has  the  flow-through  ventilation system described 
later  in  this  section. 
Air Conditioning 
Your  system  has three  air  conditioner  settings  in 
addition  to  the  standard  climate  control  system.  Before  using 
your  air  conditioner 
on very hot  days, open the 
windows  long  enough  to  let hot inside  air  escape.  This 
reduces  the  amount  of work your  air  conditioner's 
compressor  will have 
to do, which should  help  fuel 
economy. 
MAX: Use for  maximum  cooling.  This  setting 
recirculates  much of the  air  inside  your  vehicle 
so it 
maximizes  your  air  conditioner's  performance  and your 
vehicle's  fuel economy. 
NORM: Use  for  normal cooling  on hot days.  This 
setting  cools  outside  air  and directs  it  through  the 
instrument  panel  outlets. 
BI-LEV: Use on cool, but sunny  days.  This  setting 
brings 
in the  outside  air, but  directs it in two ways.  The 
cool  air 
is directed to the upper portion  of your  body 
through  the  instrument  panel outlets, but slightly 
warmer  air  is directed  through the heater  ducts  and 
defroster  vents.  At  times  this  temperature  difference 
may  be  more  apparent than  others. 
The  air  conditioner  compressor  is enabled  in all  three  air 
conditioning  positions.

Rear  Window Defogger 
cl The  rear window defogger 
uses  a warming  grid 
remove  fog  from  the 
window.  to 
rear 
1 
Press  the defogger  switch.  The indicator light will glow. 
If  your vehicle  is traveling under 
45 mph (70 km/h), the 
rear  window defogger will turn  off automatically  after 
about 
10 minutes of use. If your vehicle  is traveling 
over 
45 mph (70 km/h), the  defogger will operate 
continuously.  You can turn the defogger  off  by turning 
off 
the ignition  or pressing the switch again. 
Do not attach  a temporary vehicle license across the 
defogger grid on the rear window. 
NOTICE: 
Don’t  use  a  razor  blade  or  something  else  sharp 
on  the  inside 
of the  rear  window. If you do, you 
could  cut  or damage  the  warming  grid,  and  the 
repairs  wouldn’t  be  covered  by 
your warranty. 
Flow-Through  Ventilation System 
Your  Oldsmobile’s  flow-through  ventilation  system  supplies 
outside 
air into the  vehicle  when  it is moving.  Outside air 
will also enter  the  vehicle  when  the  fan  is  running. 
Ventilation  Tips

Keep the hood  and front  air inlet  free of ice,  snow,  or 
any  other  obstruction (such 
as leaves).  The heater 
and defroster  will  work far better, reducing the 
chance  of fogging the inside  of your windows. 
When  you enter 
a vehicle  in cold weather,  turn the 
fan  control to 
HTGH for  a  few moments before 
driving 
off. This  helps  clear the intake  ducts of snow 
and moisture, and reduces the chance  of fogging  the 
inside 
of your windows. 
Keep  the  air  path  under  the  front  seats  clear 
of objects. 
This  helps  air  to  circulate  throughout  your  vehicle. 
3-4  

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 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. 
Recreational  Vehicle Towing 
There may  be  times when you want to  tow your 
Oldsmobile behind another vehicle  for use  at your 
destination.  Be sure  to use  the proper towing  equipment 
designed  for recreational towing. Follow the instructions 
for the towing equipment.

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. 
0 Stop  after  high  speed driving. 
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. If  you have an air  conditioner, turn it off. 
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 (03) or  DRIVE  (D)  for 
automatic  transaxles. 
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. 
5-13  

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. 
r 
NOTICE: 
Engine  damage  from  running  your  engine 
without  coolant  isn’t  covered  by  your  warranty. 
If there  seems  to  be  no  leak,  with the  engine  on  check  to 
see if the  electric  engine  fan  is running. If the  engine  is 
overheating,  the  fan  should  be  running. If it isn’t,  your 
vehicle  needs  service. 
How to Add Coolant  to  the  Coolant  Surge 
Tank 
If you haven’t  found a problem  yet,  but  the  coolant  level 
isn’t  at 
FULL COLD, add  a 50/50 mixture  of clean 
water (preferably  distilled)  and a  proper  antifreeze at the 
coolant  surge  tank, but be sure  the cooling  system, 
including  the  coolant  surge  tank  pressure  cap, 
is cool 
before  you do it. 
(See “Engine  Coolant”  in the  Index  for 
more  information  about  the proper  coolant  mix.)
