Controls in detail
Automatic climate control*
The automatic climate control is operation-
al whenever the engine is running. You can 
operate the climate control system in ei-
ther the automatic or manual mode. The 
system cools or heats the interior depend-
ing on the selected interior temperature 
and the current outside temperature.
Nearly all dust particles, pollutants and 
odors are filtered out before outside air en-
ters the passenger compartment through 
the air distribution system.
The air conditioning will not engage (no 
cooling) if the AC
OFF
 mode is selected 
Setting the temperature
Use temperature controls 1 and 14 for the 
left side or 6 and 7 for the right side to 
separately adjust the air temperature on 
each side of the passenger compartment. 
You should raise or lower the temperature 
setting in small increments, preferably 
starting at 72°F (22°C).
Increasing
Push temperature control 1 and/or 6.
The automatic climate control system 
will correspondingly adjust the interior 
air temperature.
Decreasing
Push temperature control 7 
and/or 14.
The automatic climate control system 
will correspondingly adjust the interior 
air temperature.
Adding outside air
Turn thumbwheel 3 in dashboard 
(
page 156) to increase airflow of out-
side air through air vents for center, left 
and right sides and rear passenger 
compartment.
Warning!
