Climate control
The 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 170).
Setting the temperature
Use temperature controls1 and7 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
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!
G
Follow the recommended settings for heat-
ing and cooling given on the following pag-
es. Otherwise the windows could fog up,
impairing visibility and endangering you and
others.iIf the vehicle interior is hot, ventilate
the interior before driving off.
Keep the air intake grille in front of the
windshield free of snow and debris.
Do not obstruct air flow by placing ob-
jects on the air flow-through exhaust
slots below the rear window.
