152 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 157).

Use temperature controls2 and3 to sepa-
rately adjust the air temperature on each
side of the passenger compartment. You
should raise or lower the temperature set-
ting in small increments, preferably start-
ing at 72°F (22°C).Increasing
