Climate Control System
Using Automatic Climate Control
The automatic climate control system maintains the interior temperature you select.
The system also selects the proper mix of heat ed or cooled air that raises or lowers
the interior temperature to your pr eference as quickly as possible.
Use the system when the engine is running.

2. Adjust the interior temperature using the driver’s side or passenger’s side
temperature control switch.
3. Press the ( ON/OFF) button to cancel.1Using Automatic Climate Control
If any buttons are presse d while using the climate
control system in auto, the function of the button
that was pressed will take priority.

controlled automatically.
To prevent cold air from bl owing in from outside, the
fan may operate at low speed for a while after the
AUTO button has been pressed.
During idle-stops, the climate control system may
have reduced cool ing performance.
To return it back to the original condition, press the
Auto Idle Stop system OFF button to cancel idle-stop.
If the interior is very warm, you can cool it down
more rapidly by partial ly opening the windows,
turning the system on auto, and setting the
temperature to low. Change the fresh mode to
recirculation mode until the temperature cools down.
When you set the temperat ure to the lower or upper
limit, Lo or Hi is displayed.
Pressing the ( ON/OFF) button switches the
climate control system be tween on and off. When
