Engine  Coolant  Heater (If Equipped) 
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. 
To Use  the  Engine  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 AC outlet. 
/1 CAUTION: 
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.

Your vehicle  has  air outlets  that  allow  you  to  adjust  the 
direction  and  amount  of airflow  inside  the  vehicle.  Push 
the  outlet  up  or  down  to  direct  airflow  to  your 
preference.  Increase  or  reduce  the  amount  of  airflow  by 
opening  and  closing  the louvers.  Opening  and  closing 
the  louvers 
will also direct  airflow  from  side-to-side. 
If you have  the  rear  seat  passenger  outlet,  it's  attached  to 
the  back 
of the  console.  You can  adjust  the airflow 
toward  either  seating  area,  the floor  or  upward.  Turn  the 
end 
knobs up  and  down  to  direct  airflow.  Increase  or 
reduce  the  amount  of airflow  by adjusting  the  lever 
between 
the two  rear  vents  up or  down.  Open  and  close 
the  louvers  to direct  airflow  from  side-to-side. 
Ventilation  Tips 
0 Keep  the  hood  and  front  air inlet  free of ice,  snow  or 
any other  obstruction such as  leaves.  The heater and 
defroster  will  work  better,  reducing  the chance  of 
fogging  your  windows. 
0 When  you  enter  a  vehicle  with  the standard system in 
cold  weather,  select  HEATER  to  supply air through  the 
floor outlets.  Then turn the  fan  on high for  a  few 
moments  before  driving  away. 
This will blow  moist air 
from  the  intake  outlets  toward  the floor, not  the 
windshield.  It reduces  the  chance 
of fogging your 
windows. If you have  the  electronic  system,  the AUTO 
setting will do this for you. Manual  operation of the 
electronic  system in the  HEAT mode will also supply 
air through  the  floor  outlets. 
Keep the air path  under the front  seats  clear  of  objects. 
This helps air to  circulate  throughout your vehicle. 
0 When  the  engine  idles  for a  long  time,  the  exterior 
temperature  sensor  may  cause  the  system  to  blow 
air 
that  is  too  cool.  Once  the vehicle  is moving  again  the 
system 
will try to  maintain  the  set  temperature  inside 
your  vehicle. 
When  you start your  vehicle  and  the EXT TEMP 
display  flashes  (electronic system only) for some  time, 
the  system  may 
need repair. See your  Pontiac  dealer.  

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 
fiiy on  both  vehicles  involved  in 
the  jump 
start procedure. Put an 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

If you  leave  your  radio on, it  could  be  badly 
damaged.  The  repairs  wouldn’t  be  covered  by

Engine Overheating 
You will  find  a  coolant  temperature  gage  or the  warning 
light  about  a  hot  engine  on  your  vehicle’s  instrument 
panel.  See  “Coolant  Temperature  Gage”  and  “Coolant  Temperature  Warning 
Light” in  the  Index. 
If Steam Is Coming From Your  Engine 
1 
A CAUTION: 
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  waming  but  see or hear no 
steam,  the  problem  may  not  be  too  serious.  Sometimes  the  engine  can  get  a  little  too  hot  when  you: 
0 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. 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 trafEc jam, shift to NEUTRAL (N); 
otherwise, shift to the  highest  gear  while 
driving 
-- AUTOMATIC OVERDRIVE (@) 
or DRIVE (D). 
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 oflthe 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.

If you  have  the 3800 Supercharged  engine (VIN Code 
l), use  premium  unleaded  gasoline  rated  at 91 octane 
or  higher.  With  the 
3800 Supercharged  engine,  in an 
emergency,  you  may  be  able  to  use  a  lower  octane -- as 
low  as 
87 -- if heavy  knocking  does  not  occur. If you 
are  using 
91 or  higher  octane  unleaded  gasoline  and 
you  hear  heavy  knocking,  your  engine  needs  service. 
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  fwels  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  Pontiac  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 
Pontiac  dealer  for  service.

Filling a Portable Fuel Container 
I 
1 A CAUTION: I 
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: 
Dispense  gasoline  only  into approved 
containers. 
Do not  fill a container  while it is  inside  a

Checking  Things  Under the Hood 
The  following  sections  tell you how  to  check fluids, 
lubricants  and  important  underhood parts. 
A CAUTION: 
I 
An electric  fan  under  the  hood  can start up  and 
injure  you  even  when  the  engine 
is not running. 
Keep  hands,  clothing  and tools  away from any 
underhood  electric  fan. 
A CAUTION: 
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.
