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).
Setting the temperature
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

grees to the right.
The climate control system will corre-
spondingly adjust the interior air tem-
perature.

!Heavy accumulation of snow and ice
should be removed before activating
the defroster.
The defroster is automatically turned
off after approximately 6-17 minutes of
operation depending on the outside
temperature and vehicle speed.
If several power consumers are turned
on simultaneously, or the battery is
only partially charged, it is possible that
the defroster will automatically turn it-
self off.
When this happens, the indicator lamp
inside the switch starts blinking.
As soon as the battery has sufficient
voltage, the defroster turns itself back
on.
iThe rear window defroster uses a large
amount of power. To keep the battery
drain to a minimum, turn off the de-
froster as soon as the rear window is
clear.
