If your car is equipped with a dual automatic temperature control system, it allows you to set a different temperature for the driver side and passenger side. Once you’ve set the temperature, the system will automatically maintain it until you change a setting. Here’s how the controls work:

  • Auto Driver Side: This activates the automatic temperature control system for the driver. If the passenger side is not on auto and programmed separately, it will have the same temp as the driver side. The system automatically controls most aspects to keep the car at the preset temp, including:

    • Fan speed
    • Temperature
    • Vent selection
    • Fresh or recirculated air
    • A/C on and off
    • Heating
  • Rear Defrost: Push this button to turn on the rear glass defroster.

  • Front Defrost: Push this to turn on the front defroster.

  • Defrost and Lower Vents: This turns on both the front defrost and the lower vents at your feet.

  • Power: This turns the system on and off. Turning it right and left adjusts the fan speed manually, as well.

    • Upper Vent: Push this to choose upper vent operation only.
  • Split Vent: Push this to direct air from both the upper and lower vents.

  • Lower Vents: Push this to have air directed only out of the lower vents.

  • Auto Passenger Side: Sets the temperature desired for the passenger side. If this is not set, the passenger side will default to the same temp as the driver side.

  • Heated Seats: You have two heated seat buttons (one for each front seat). Push them to turn the heated seats on or off.

  • Recirculated Air: Push this to change from fresh air to recirculated air and back again.

  • Max A/C: Turns on maximum air conditioning.

  • A/C: Turns on the normal air conditioning.

  • Outside Temp: This readout tells you what the temperature is outside the vehicle.
