146 Controls in detailClimate controlThe climate control is operational whenev-
er the engine is running. You can operate
the climate control system in either the au-
tomatic or manual mode. The system cools
or heats the interior depending on the se-
lected interior temperature and the cur-
rent 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
(
page 150).
Setting the temperature
Use the temperature controls2 and3 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
Turn the control slightly to the right.
The climate control system will corre-
spondingly adjust the interior air tem-
perature.
Decreasing

Turn the control slightly to the left.
The climate control system will corre-
spondingly adjust the interior air tem-
perature.
Warning!
