These buttons  control climate control ON/OFF, air 
intake,  front defrost,  rear defrost and the air 
conditioning  operation. 
FRONT Press  the  FRONT defrost button  to 
quickly  remove  fog  or frost from the windshield. This 
setting  directs  most  of the airflow  to the windshield and 
a  small  amount  toward 
the lower and side window 
outlets.  The light  on  the button  will come on and the 
digital  display  will  show  the defrost mode symbol and 
fan  speed  when  the  front defrost mode  is being used. 
Pressing  FRONT defrost again will return the system to 
the last operating  mode. 
If the system  is in  FRONT defrost  when you shut the 
engine 
off, it  will  restart  in FRONT  defrost unless  the 
engine  is off  for  longer  than 40 minutes.  If the engine  is 
off longer  than 40 minutes, the system  will restart in the 
operating  mode you  had  set prior to FRONT defrost. 
OFF: Press the OFF button  to turn  off  the climate 
control  system. This is  the only setting that fully shuts 
off the fan. The digital display  will show only the 
outside  temperature.  You can still adjust the driver-set 
temperature,  the  passenger temperature offset and the  air 
intake  mode while  in 
OFF. 
a NC: This button turns the air conditioning 
compressor  on  or 
off, except  in the FRONT defrost  mode. 
The  light  on  the  A/C button  will  come  on when 
the 
compressor  is  operating  in  either  the  automatic or manual 
mode.  The 
air conditioning  may also be forced off at  high 
engine  speeds.  The light  on  the  A/C  button  will  flash  if 
pressed  when 
air conditioning  operation  is not  allowed. 
The air conditioning  cools and dehumidifies 
air coming 
into  the vehicle.  It also  operates in defrost  to  help 
remove moisture from the  vehicle. The  air conditioning 
does  not operate  at temperatures below approximately 
35°F  to 40°F  (2°C  to 4°C).  If the  system  is  operating  in 
the  AUTO  mode, turning the air conditioning  off will 
delete  AUTO  from the digital display and show current 
mode and fan settings.  The AUTO  button  must  be 
pressed  to return to the automatic mode operation. 
from  the  outside.  The light  on 
this air intake  button 
will  come  on  to  show  when  it is operating.  When  in 
the 
AUTO mode,  the  system  automatically  selects FRESH 
AIR instead  of  RECIRCULATE,  as  required,  to  control 
the  temperature 
in the  vehicle. By pressing FRESH AIR, 
the  system  will  lock  into  the  fresh air mode . Any 
adjustment  to  the air intake  must  then  be made  manually. 
FRESH AIR should  be used  when  trying  to defrost or 
defog  windows  to  help  reduce  moisture  inside the vehicle.

Downloaded from www.Manualslib.com manuals search engine Outside  Air  Temperature  Sensor 
This sensor is  located  in  the air intake under the front 
bumper  of the  vehicle.  Information from this sensor 
is  used  for the  outside  air temperature readings 
shown  on  the  digital display  for the automatic 
climate  control system. 
If the outside temperature goes  up, the displayed 
temperature  will  not  change until: 
0 The vehicle’s  speed  is above 20 mph (32 km/h) 
for one and  a  half  minutes. 
The vehicle’s  speed  is above 45 mph (72 km/h) 
for one  minute. 
These  delays  help  prevent  false readings. 
If the 
temperature  goes  down, the outside temperature 
display  is updated  immediately. 
If  your  vehicle  has  been  turned off for more  than three 
hours,  the  current outside temperature  will be shown 
when  you  start  the vehicle. 
If it has been turned  off for 
less  than  three  hours,  the  temperature will be recalled 
from  the  previous  vehicle operation. 
Inside  Temperature  Sensor 
This sensor is located  just left of the ignition  switch. 
The  automatic climate control system uses this sensor 
to  receive information 
so if  you  block or cover it,  the 
system  will  not  function  properly. 
Air  Conditioning 
On very  hot days, your vehicle  will cool  down more 
quickly and economically  if you open the windows 
long enough to let hot inside air escape.  Then keep your 
windows closed  in order to allow the  air conditioning 
to  work best.  Maximum cooling will occur when the 
RECIRCULATE setting  is operating, airflow direction  is 
in  the upper mode, and the temperature control knob (on 
a  manual climate control system)  is turned  all the  way to 
the blue area. These settings  will be selected by  the 
Automatic Electronic Dual Climate Control  System if 
operating  in AUTO when  maximum cooling is required. 
When  the 
air conditioning  is on, you  may sometimes 
notice slight changes  in your  vehicle’s  engine 
performance and power.  This  is normal.  The system 
is 
designed to help  fuel economy while maintaining the 
desired cooling level. 
The 
air conditioning  removes  moisture  from the air, so you 
may  notice  water  dripping  from under  your  vehicle  when 
it  is  idling  or  after  it has  been  turned 
off. This is  normal.

Downloaded from www.Manualslib.com manuals search engine Heating 
The  heater works best if  you  keep your windows closed. 
Maximum  heating will occur when airflow  direction 
is  in  the  lower mode  and the temperature  control knob 
(on  a  manual  climate  control  system) is  all  the  way in 
the  red  area.  These  settings  will  be selected  by the 
Automatic  Electronic Dual Climate Control  System if 
operating  in AUTO  when maximum heating  is  required. 
The  BI-LEVEL  setting is designed  for use  on  sunny 
days  when  the air is only moderately warm  or  cool. 
On  days  like  these, the sun  may  adequately  warm 
your  upper  body, but your lower body  may not be 
warm  enough.  The  BI-LEVEL setting will direct 
cooler  airflow  to your  upper  body  and  warmer air 
to  the  floor  area. 
If  you  have  the optional  engine coolant heater  and  use 
it  during  cold  weather 
0°F (- 18OC) or lower, your 
heating  system will provide heat more quickly because 
the  coolant  is already warmed.  See  “Engine  Coolant 
Heater”  in the  Index. 
Defogging  and  Defrosting 
To rapidly defrost  the windshield,  the  FRONT  defrost 
mode  (electronic dual climate control  system)  or  defrost 
mode (manual  control system)  should  be  used  and  the 
fan  speed  should  be adjusted  to  the  highest  speed.  With 
the manual  control system, 
turn the  temperature  control 
knob all the  way  to the red  area. 
To keep  the windshield clear  and  provide  heated  air  to 
the  floor  area of 
the vehicle,  use  the  DEFOG  setting. 
Your  vehicle  is equipped  with side window  defogger 
vents located  near the side  rearview  mirrors.
