Air  Conditioning 
On  very  hot  days,  open  the  windows long enough  to’let 
hot,  inside  air  escape.  This  reduces  the time  the 
compressor  has to  run,  which  should  help  fuel economy. 
For  quick  cool-down  on very  hot days,  use 
MAX with 
the  temperature  knob  all 
the way  in  the blue area.  If  this 
setting  is used  for long  periods  of  time,  the  air in  your 
vehicle  may  become too 
dry. 
For normal  cooling  on hot  days,  use  VENT  with  the 
temperature  knob  in  the  blue  area and  the  A/C button 
pushed  in.  The system  will  bring  in outside  air  and 
cool  it. 
On  cool  but  sunny  days,  the  sun  may  warm  your  upper 
body,  but  your  lower body  may  not  be  warm  enough. 
You  can  use  BI-LEVEL  with  the temperature  knob  set 
for  comfort  and  the  A/C button  pushed  in. The  system 
will  bring  in  outside  air and  direct  it to  your  upper  body, 
while  sending  slightly  warmed  air 
to your  lower  body. 
You  may  notice  this  temperature  difference  more at 
some  times  than  others. 
Heating 
On  cold  days,  use  FLOOR  with  the  temperature  knob  all 
the  way  in  the  red  area.  The system  will  bring  in  outside 
air,  heat  it and  send  it to the  floor  ducts. 
If  your  vehicle  has  an engine  coolant  heater,  you  can  use 
it  to  help  your  system  provide  warm  air  faster  when  it’s 
cold  outside  (0°F (-18°C)  or lower).  An  engine  coolant 
heater  warms  the  coolant  your  engine  and  heating 
system  use  to  provide  heat.  See “Engine  Coolant 
Heater”  in the  Index. 
Ventilation 
For  mild  outside  temperatures  when  little  heating  or 
cooling  is needed,  use  VENT  to  direct  outside  air 
through  your  vehicle.  Your vehicle  also  has  the 
flow-through  ventilation  system  described  later  in 
this  section. 
Defogging  and  Defrosting 
Your  system  has  two  settings  for  clearing  the  front  and 
side  windows.  To defrost  the windows  quickly,  use 
DEFROST  with  the  temperature  knob  all  the  way  in  the 
red  area.  To warm  passengers  while  keeping  the 
windows  clean,  use  DEFOG.

Air  Conditioning  with  Automatic  and 
-Auxiliary  Temperature  Control 
With  this  system, you set  a  temperature. You can  then 
either let  the  system  adjust  airflow  and  force  to  maintain 
. the temperature,  or you can  manually  adjust  the  flow 
and  force.  The system  works  best  if  you  keep  your 
windows  closed  while  using  it. 
Fan Knob 
The left knob selects  the  force of air you  want  when  the 
system 
is not  in AUTO.  The display  will  show  the 
speed.  To turn  the  system  off,'push the 
knob. , 
Driver  Temperature Knob 
The right knob sets  the  temperature  for the  entire  system 
when  the  light  on the  PASS  button  isn't  lit. If  the  light  is 
lit,  the  knob  sets  the  temperature  for the  driver.  Turn  the 
knob  toward  red  (clockwise)  to raise  the temperature. 
Turn  it toward  blue  (counterclockwise)  to lower  the 
temperature. 
The display  will  show  your  selection  for a 
few  seconds,  then  the  outside  temperature  will  show.  If 
you  push  the knob,  the  system  will  control  the  fan  speed 
and  airflow.  AUTO  will  show  on the display.

Passenger  Temperature Knob 
The knob  on the 
passenger's  door adjusts 
the  air temperature 
on 
the passenger's  side so 
it is  warmer  or colder 
than  the temperature  set. 
by  the  driver. 
Push the  PASS button  on the  system  face 
so the light 
on  it is lit.  Turn the knob  on the door  toward  red 
(clockwise) to raise the temperature.  Turn it toward  blue 
(counterclockwise) to lower the temperature. 
Mode  Buttons 
The  center  panel  has  several  settings  to  control  the  direction \
of  airflow  when  the  system  is  not  in  AUTO.  The  indicator 
light  on  the  button  will  glow  when  the  button  is  pressed. 
RECIRC: This setting can recirculate  either the air 
inside  of your  vehicle  or outside air  and  send  it  through 
the  instrument panel outlets. Press  this button once  and 
it will recirculate outside  air.  Press it again  and  it will 
recirculate  the air inside 
of your  vehicle. This setting  is 
available  in  LOWER,  DEFOG,  UPPER  and  BI-LEV. 
UPPER: This setting brings  in outside  air and  directs it 
through  the instrument panel outlets. 
BI-LEV: This setting  brings in the outside air  and 
directs it  two  ways.  Half  of  the air is directed  through 
the  instrument  panel outlets.  Most of the remaining  air is 
directed  through the floor  ducts  and 
a little to the defrost 
and  side  window  vents. 
LOWER: This setting sends  most of the air through  the 
ducts  near  the floor.  The rest comes out  of the defrost 
and  side  window  vents. 
DEFOG: This setting  allows  half  of  the air to  go  to  the 
floor  ducts  and  half  to  the  defrost  and  side  window  vents. 
DEF: This setting directs  most of the air through  the 
defrost  and side  window  vents.  Some of the air goes  to 
the floor ducts.  The air conditioning  compressor  will  run 
automatically  in this setting  unless the outside 
temperature is  below 40°F (4.5"C). 
Automatic Control 
For  the  most  efficient  operation,  you  should  press  the knob 
and  set  the  system  temperature.  The  system  will  select  the 
best  fan  speed  and  airflow  settings  to  keep  you  comfortable. 
The 
air conditioning  compressor  will  run if the  outside 
temperature  is  above  40°F 
(4.5 "C). You  may  notice  a delay 
of  three  to  four  minutes  before  the  fan  comes  on.

Manual Control 
If  you  prefer  to  manually  control  the  heating,  cooling and  ventilation  in  your  vehicle,  set  the  system  to  the 
temperature  and  fan  speed  you  want.  Next,  push  the 
desired  airflow  direction  pushbutton.  The system  will 
try to  maintain  the  temperature  you set using  the  mode 
you  select.  The following  suggestions  will  help  the 
system  run  more  efficiently  in  manual  mode. 
Air  Conditioning 
On  very  hot  days,  open  the  windows  long  enough  to

If  this  setting  is used  for long  periods  of  time,  the air 
in 
your  vehicle  may  become  too  dry. 
For  normal  cooling  on hot days,  use  UPPER  with  the 
A/C button  pushed  in.  The system  will  bring  in  outside 
air  and  cool 
it. 
Heating 
On  cold  days,  use  LOWER.  The system  will  bring in 
outside  air,  heat it and  send  it to  the  floor  ducts. 
If  your  vehicle  has  an  engine  coolant  heater,  you  can use 
it to  help  your  system  provide  warm  air faster  when  it’s

Ventilation  System Ventilation Tips 
Adjust the direction  of airflow  by moving  the 
louvered vents. 0 
Your  vehicle’s  flow-through ventilation  system supplies 
outside air  into the vehicle  when it is  moving. Outside 
air  will  also enter  the vehicle  when the air conditioning 
0 
fan  is running. 
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  far better,  reducing the chance 
of 
fogging  the inside  of your  windows. 
When  you  enter a vehicle  in  cold  weather,  set the 
mode  to 
FLOOR or  LOWER  and  the  fan  to  the 
highest  speed 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.

Rear Window Defogger Do not  'attach  anything like a  temporary  vehicle  license 
or decal  across  the  defogger  grid. 
The  rear  window  defogger  uses  a  warming  grid to 
remove  fog  from  the  rear window.  Press  the  button  to 
turn  the  defogger  on. It will  turn  itself  off  after  about 
10 minutes.  If  you  turn  it on  again,  the  defogger  will 
only  run  for about  five minutes  before  turning  off.  You 
can also  turn it 
off by  turning off the  ignition  or  pressing 
the  button  again.
