Dual Automatic Climate Control
System
With this system, you can control the heating,
cooling and ventilation in your vehicle.
You can select different climate control settings for
the driver and passengers.

Driver's Side Temperature Knob
The driver's side knob is used to adjust the
temperature of the air coming through the system
on the driver's side. The temperature can be
adjusted even if the system is turned off. This is
possible since outside air will always flow through
the system as the vehicle is moving forward
unless it is set to recirculation mode. See
"Recirculation" later in this section.
Turn the knob counterclockwise or clockwise to
lower or increase the cabin temperature. The
display will show the temperature setting
decreasing or increasing and an arrow pointing to
the driver will be displayed under and to the
left of the temperature setting.
