OPTION Omv 
In very cold  weather, 0 F (-18 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 coolant  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. 
I NOTICE: 
I- 
I 
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  a  Cadillac - 
dealer  in the  area  where  you’ll  be parking  your  vehicle.  The dealer  can 
give  you  the best  advice  for that  particular  area.

A/C Purge 
If your  vehicle  is  sitting  out  on a hot day  and  you  have  it set  on  AUTO, 
the  air will  first  flow  out  the  floor air ducts  for a few  seconds.  That is 
normal.  This  is  to 
expel hot -air in the  air  ducts. As the  air is  cooled,  the 
flow  will  move  through the A/C  outlets. 
If you  start  your  vehicle  with  the 
fan  setting  on  “HI”  it will  skip  the A/C  Purge. 
Cold  Weather  Purge 
On cold  days  when  your  system  is  first  turnea on, in either  the  AUTO’br.. 
ECON setting  and the fan setting 
is not  on “HI”, a small  amount  of ah ::. 
will  flow  through the defroster  duct  while-  the system is waiting for the 
engine  coolant  to warm  up enough  to provide  heat. This  prevents  your 
breath  from  fogging  your  windshield.  As  the coolant  warms  up,  the 
blower  fan speed  will gradually  increase  and air will  flow  from the  heater 
outlets,  with  some  air bleed  to  the  windshield  to prevent  fogging  under 
most  normal  conditions.

Manually  Recirculate  Inside  Air 
There  may be times  when  you  don’t  want  air from  the outside. To 
recirculate  the air from  the inside  only  in  either “AUTO”  or  “ECON” 
setting,  just set  the  temperature  to 
60 F (16 C) and  adjust  your fan 
speed,  if the  air  quantity  is too  high. 
DEFOG 
Push  this  button  to  divide the  air  between  the windshield  and the  heater 
ducts. 
This is  useful  when  fog  appears on the  windshield  or side  glass  due 
to  a sudden rain  or snowy  conditions.
