Automatic Operation
AUTO (Automatic): The system
automatically controls fan speed, air
delivery, and air conditioning in
order to heat or cool the vehicle to
the desired temperature. When the
indicator light is on, the system is in
full automatic operation. If the air
delivery mode or fan setting is
manually adjusted, the auto
indicator turns off and displays
will show the selected settings.
1. Press the AUTO button.
2. Adjust the temperature to a
comfortable setting between
21°C (70°F) and 27°C (80°F).
Choosing the coldest or warmest
temperature setting will not
cause the system to heat or
cool any faster.
To avoid blowing cold air in
cold weather, the system delays
turning on the fan until warm air
is available. The system starts
out blowing air at the floor,
but can automatically change
modes as the vehicle warms
up to maintain the chosen
temperature setting. The length
of time needed for warm up
depends on the outside
temperature and the length
of time that has elapsed since
the vehicle was last driven.
3. Wait for the system to regulate.
This may take from 10 to
30 minutes. Then adjust the
temperature, if necessary.

Q / R (Temperature Control):
The temperature can be adjusted
separately for the driver and the
passenger. Press to increase or
decrease the automatic temperature
settings.
PASS (Passenger Climate
Control): Press to set a different
temperature for the passenger.
Then adjust the passenger
temperature buttons to a
comfortable setting.
Pressing the PASS button again
automatically sets the passenger's
temperature to the driver's setting.
Turning the passenger's
temperature display off does
not shut the passenger's climate
control system off.
