How to Turn on the Heater in Nissan Sylphy?
2 Answers
Here are the steps to turn on the heater in Nissan Sylphy: 1. After starting the Dongfeng Nissan Sylphy, wait for about 5-6 minutes until the water temperature reaches the normal level, then you can turn on the heater. 2. Adjust the air conditioning circulation mode to internal circulation. 3. Switch to the heater mode, which is indicated by the red zone. 4. When using the heater, there is no need to press the air conditioning button. Pressing the air conditioning button activates the compressor, which means turning on the cold air, but the heater is not required as it transfers part of the heat initially dissipated by the radiator to the cabin. Therefore, turning on the cold air consumes some engine power, while the heater does not affect the power at all. 5. Adjust the air conditioning to a suitable level and set the direction of the air vents.
I've been driving a Nissan Sylphy for several years, and using the heater is quite simple yet practical. In winter, start the engine first but don't drive off immediately—wait a minute or two to let the coolant warm up a bit. The climate control panel is usually on the center console; locate the temperature knob and turn it clockwise to raise the temperature above, say, 25°C. Simultaneously, check the A/C button—if it's lit, press it to turn off since the heater relies on engine heat, and running the compressor wastes fuel. I usually set the fan speed to medium or high for faster airflow and quicker warming. For air direction, aim it at the feet or windshield to defog without drowsy face blasts. Heat may take ~5 minutes of driving to kick in. Fuel-saving tips: avoid max fan speed (higher RPM increases consumption) and keep windows closed for better insulation. Replace the cabin air filter regularly—clogging reduces airflow. Ultimately, heating enhances safety, especially in low-light conditions for clearer visibility.
