How to Turn on the Heater in a Nissan Sylphy?
3 Answers
The method to turn on the heater in a Nissan Sylphy is as follows: 1. Press the knob with red and blue color buttons; 2. Wait for 5 to 10 minutes after ignition; 3. When the water temperature rises to the normal level, you can turn on the heater. Precautions for using the heater: 1. Wait for 8 to 15 minutes after the car starts until the water temperature reaches the normal level before turning on the heater; 2. Adjust the air conditioning circulation mode to internal circulation and set it to the heater mode, which is the red zone; 3. Do not turn on the air conditioning. The heater utilizes the car's own heat cycle to save energy. Adjust the fan speed and set the air conditioning to a suitable level to direct the airflow; 4. When parking for a long time, turn off the heater in time or roll down the window slightly to prevent carbon monoxide poisoning.
As a Sylphy owner who has studied its AC system, let me tell you that turning on the heater is simple: First start the engine and wait for the coolant temperature to rise slightly, since the heating relies on engine heat. Then locate the temperature knob on the center console – it typically has red (warm) and blue (cool) ends – just turn the knob toward the red side to a higher setting, like above 25°C. If you want quicker heating, adjust the fan speed knob from low to high as preferred. For automatic AC versions, it's even easier – just press the AUTO button and the system will automatically regulate temperature and airflow; manual adjustment is needed for non-AUTO versions. When using the heater, remember to set the vent direction, such as toward footwells or windshield defrosting. Avoid pressing the A/C button in winter as it increases fuel consumption. Regularly check the cabin air filter to prevent clogging that might affect heating efficiency. Overall it takes just minutes – the Sylphy's heating system is quite reliable.
I use the heater in my Sylphy every day, especially when picking up my kids from school in winter: After starting the car, I wait for the engine to warm up, usually for a minute or two until the temperature gauge rises. Then, I turn the temperature knob to a warm setting. The fan button also needs to be turned on, selecting an appropriate fan speed—not too high. If using automatic air conditioning, pressing the AUTO button makes things much easier as it adjusts the temperature automatically, requiring less attention. It's important to set the air vents so they don't blow directly at the face to avoid dryness and discomfort. Turn off the A/C light, as it's only used for cooling in summer. Use the external circulation for fresh air in warm weather and the internal circulation for faster heating in cold weather. Turning on the heater too quickly might cause the windows to fog up, so remember to switch to the front windshield defrost mode—just turn the knob. The Sylphy's heater works well and is easy to maintain.
