9 FRONT This  setting brings in outside  air  and 
directs  most of the  air  through  the  defrost  vent. Some 
of 
the air also goes  to  the  floor  ducts  and the  side  window 
defogger  outlets.  The  indicator  on  the button will light 
and WINDSHIELD  will  be  lit  in  the display. 
The air 
conditioning  compressor will run automatically  in 
this  setting  unless the outside  temperature  is  below 
40°F (4°C). 
VENT: This pushbutton turns  the  air  conditioning 
compressor on and 
off. The  indicator  lights  when the 
compressor is turned  off.  Recirculation is not  permitted 
when  the compressor 
is off.  The  system will  try to 
control  the temperature  automatically,  but without 
the compressor. 
Vent  is not  permitted  in FRONT  defrost  mode. If the 
vent button is pushed  while  in FRONT  defrost  mode, 
the  indicator  will light for  one second and then turn off. 
RECIRC: This  setting  recirculates  much of the air 
inside  your vehicle.  This setting is not permitted in 
FRONT  defrost  mode  and is only permitted in 
WINDSHIELD/FLOOR  mode  if the compressor is 
turned 
on. The  indicator  light  will be lit when 
recirculation  is  engaged, but will light  for 
one second 
and  then  turn off  if  selected  when not  permitted. 
Air  Conditioning 
On very hot  days, open the windows  long enough  to  let 
hot,  inside  air  escape.  This  reduces the  time 
for the 
vehicle  to  cool  down. 
For  a  quick cool-down 
on very hot  days, use MAX with 
the  temperature  knobs 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 NORM with  the 
temperature  knobs in the  blue  area.  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-LEV and set  the  temperature  knob  to a 
comfortable  setting.  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 Ventilation  System 
On cold days, use HTR with  the temperature knobs 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 wm air  faster  when it’s 
cold  outside 
(0°F (-18°C) or  lower).  An engine  coolant 
heater  wms  the coolant  your engine  and heating 
system  use  to  provide  heat.  See  “Engine Coolant 
Heater”  in the  Index. 
Defogging  and  Defrosting 
Your  system has two settings  for  clearing the  front  and 
side  windows. 
To defrost  the  windows quickly, press the 
FRONT button; set the temperature to 90 OF (32”C), 
select  high fan speed and turn the DUAL button off. To 
warm passengers while keeping  the windows clear, push 
the  AIR 
FLOW button until  WINDSHIELDFLOOR 
appears  in the  display.  Select  fan  speed for comfort and 
windshield clearing performance.  Adjust the direction 
of  airflow  by moving 
the vents. 
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 
fan  is running. 
If  the airflow seems  very low when the  fan knob  is 
turned 
to the highest setting regardless  of the mode 
setting, your passenger compartment  air filter  may 
need 
to be replaced.  See “Maintenance  Schedule’’ 
in the Index.

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  far better,  reducing  the chance  of 
fogging  the inside 
of your windows. 
0 When you enter  a  vehicle  in cold  weather,  adjust the 
mode knob  or button 
to FLOOR and  the  fan  to  the 
highest  speed for  a few seconds before  driving  off. 
This  helps  clear  the intake  ducts  of snow and 
moisture  and reduces the chance  of fogging  the 
inside  of your windows. 
0 Keep  the air path under  the  front  seats  clear of 
objects.  This  helps  air to  circulate  throughout 
your vehicle. 
Rear Window Defogger 
@I 
REAR 1 
1 
The  rear window defogger uses a warming grid  to 
remove  fog  from  the rear  window. Press the button 
to 
turn the rear defogger on. It  will  turn itself off after 
about 
10 minutes. The  picture above on the left  refers to 
the  defogger  button that is found on  a Manual  Single 
Zone  Climate  Control  System  or  Dual ComforTemp 
Climate Control System;  the button 
on the right is found 
on  the Dual Automatic ComforTemp  System. 
If  you  turn it on  again, the rear  defogger  will only run 
for  about  five  minutes before  turning off. You  can also 
turn it  off  by pressing  the  button again.

I NOTICE: 
Do not  attach  anything  like  a  temporary  vehicle 
license  or  decal  across  the  defogger  grid. 
I NOTICE: 
Don’t  use  a  razor  blade  or  anything  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.
