Climate Control System
On models with navigation system
In AUTO mode, the vehicle's
temperature is independently
regulated, based on the driver's and
passenger's side setting. The system
also regulates each temperature
based on the information of the sun
light sensor and the sun's position
which is updated automatically by
the navigation's global positioning
system (GPS). For example, if the
driver's side of the vehicle is getting
too much sun, the system will adjust
to a lower temperature.

press the ON/OFF button.
Keep the system completely off
for short periods only.
To keep stale air and mustiness
from collecting, you should have
the fan running at all times.
Semi-automatic Operation
You can manually select various
functions of the climate control
system when it is in fully automatic
mode. All other features remain
automatically controlled. Making any
manual selection causes the word
AUTO in the display to go out.

the fan speed and airflow. Press the
button to decrease it.
Air Conditioning (A/C) Button
This button turns the air
conditioning on and off. You will see
A/C ON or A/C OFF in the display.
When you turn the A/C off, the
system cannot regulate the inside
temperature if you set the
temperature control below the
outside temperature.
