BI-LEV: Use  on  cool,  but sunny days.  This  setting 
brings  in the  outside  air, but directs  it  in  two  ways. The 
cool  air is directed  to  the  upper portion of your body 
through the  instrument  panel  outlets,  but slightly 
warmer  air  is  directed  through the heater  ducts and 
defroster  vents. At  times  this  temperature  difference 
may  be more  apparent  than others. 
The  air  conditioner  compressor is  enabled in all three 
air  conditioning  positions. 
VENT: Use  when  outside  temperatures  are  mild,  and 
little  heating  or  cooling  is needed.  Airflow comes 
through  the  instrument  panel  outlets.  Set  the center 
control  knob  to  the temperature  desired. 
HEAT This  setting  brings  heated air through the  heater 
ducts,  and some  through  the windshield  defroster vents. 
If you have the optional engine coolant heater (engine 
block heater) and  use it during cold  weather, 
0 “F (- 18 O C) 
or lower, your heating system will more quickly provide 
heat because  the engine coolant 
is already warmed.  See 
“Engine Coolant Heater” in the Index. 
DEFOG: This  setting  divides  airflow  equally  between 
the  heater  ducts  and the windshield  defroster  vents. 
DEF: This  setting  directs  air  through the 
windshield  defroster  vents  located 
on top of the 
instrument  panel. 
Air Conditioning 
The  air  conditioner  and heater  work best if you  keep 
your windows  closed while using  them. Your vehicle 
also has  the flow-through  ventilation system described 
later 
in this  section. 
Your  system has  three  air  conditioner  settings in 
addition  to the standard  climate control system. 
Before using your  air  conditioner 
on very hot days, 
open  the windows  long enough  to  let hot inside  air 
escape.  This  reduces  the amount of work your  air 
conditioner’s  compressor will have  to  do, which 
should  help  fuel  economy. 
Heating 
On cold  days,  use HEAT  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 
uses to  provide  heat.  See  “Engine Coolant 
Heater” 
in the  Index.
