C60

With the C60 system, you can control the heating, cooling and ventilation in your vehicle. The system works best if you keep your windows closed while using it.

Fan Control

The knob on the left side of the control assembly controls the fan speed. To turn the fan off, turn the knob to the OFF position.

Temperature Control

The center knob on the control assembly changes the temperature of the air coming through the system. Turn this knob toward red area (clockwise) for warmer air. Turn it toward blue area (counterclockwise) for cooler air.

Mode Control

The right knob on the control assembly has several settings to control the direction of airflow.

Rear Window Defogger (REAR)

Press the button marked REAR to turn the defogger on. An indicator on the button will light. The rear window defogger uses a warming grid to remove fog from the rear window.

The rear window defogger will turn itself off after about 15 minutes. If you turn it on again, the defogger will only run for about 7.5 minutes before turning off. You can also turn the defogger off by turning the ignition off or by pressing the button again.

A/C

Press this button to turn the air conditioning on and off. The system will cool and dehumidify the air inside the vehicle when the A/C light is on
