Nissan Sentra Owners Manual: Automatic operation

Heating (A/C OFF)

The air conditioner does not activate. When you need to heat only, use this mode.

1. Press the A/C button. (A/C OFF will be displayed and A/C indicator will turn off.)
2. Use the temperature control buttons to set the desired temperature.

• The temperature of the passenger compartment will be maintained automatically. Air flow distribution and fan speed are also controlled automatically.
• Do not set the temperature lower than the outside air temperature or the system may not work properly.
• Not recommended if windows fog up

Dehumidified defrosting or defogging

1. Press the front defroster
   button on.

   (The indicator light on the button will remain in Off.)

2. Use the temperature control buttons to set the desired temperature.

• To quickly remove ice from the outside of the windows, use the fan speed control dial to set the fan speed to maximum.
• As soon as possible after the windshield is clean, press the AUTO button to return to the automatic mode.
• When the front defroster
  button is pressed, the air conditioner will automatically be turned on at outside temperatures above 36°F (2°C) (The indicator light may not illuminate). The air recirculate mode automatically turns off, allowing outside air to be drawn into the passenger compartment to further improve the defogging performance.

Cooling and/or dehumidified heating (AUTO)

This mode may be used all year round as the system automatically works to keep a constant temperature. Air flow distribution and fan speed are also controlled automatically.

1. Press the AUTObutton on. (The indicator on the button will illuminate and AUTO will be displayed.)
2. Use the temperature control buttons to set the desired temperature.

• Adjust the temperature display to about 75°F (24°C) for normal operation.
• The temperature of the passenger compartment will be maintained automatically. Air flow distribution and fan speed are also controlled automatically.
• A visible mist may be seen coming from the vents in hot, humid conditions as the air is cooled rapidly. This does not indicate a malfunction.

3. You can individually set driver’s and front passenger’s side temperature using each set of temperature control buttons. When the DUAL button or passenger’s side temperature control buttons are pressed, the DUAL indicator will come on. To turn off the passenger’s side temperature control, press the DUAL button.
