How to Turn on the Heater in the Nissan Sylphy?

Dongfeng Nissan Sylphy heater activation method: After ignition and startup, wait for 5-10 minutes until the water temperature rises to normal operating temperature, then you can turn on the heater. Adjust the air conditioning circulation mode to internal circulation. Set it to heating mode (red zone). Here are some recommendations for using the car's air conditioning system: 1. It's recommended not to turn on the heating AC immediately when warming up the car in the morning. Wait until the engine coolant temperature rises before activating the AC. Avoid setting the temperature too high as prolonged driving with high heat may cause drowsiness. 2. If the airflow from the vents is weak, check if the cabin air filter is dirty. After prolonged use of internal circulation, it's advisable to switch to external circulation or open windows for ventilation. 3. After using AC cooling, don't turn off the AC immediately. Set the blower to maximum speed to dry out moisture in the AC ducts, which can also prevent bacterial growth in the cabin filter.
I usually drive a Nissan Sylphy to commute, and turning on the heater in winter is a must. After starting the engine, it's best to wait two or three minutes to let the engine warm up, so the heater can blow warm air faster. On the dashboard's air conditioning control panel, there's usually a knob: turn it to the red high-temperature mark to switch to heating mode. Then press the fan button to activate airflow and adjust the fan speed—I find medium speed the most comfortable. Airflow direction is also important; I prefer setting it to the windshield position to prevent fogging. If the heater blows cold air, don't panic—it might be due to insufficient coolant or the system not being fully warmed up. It's recommended to check if the coolant reservoir is at the normal level and inspect it every few months. Without the heater, the car can get damp and cold, increasing the risk of catching a cold and affecting driving comfort.
As a car enthusiast, I've done some research on the Sylphy's heating system. The heating actually works by using the engine coolant, which heats up and then warms the air through a heat exchanger. The operation is simple: turn the temperature knob on the center console to the maximum heat zone, then press the fan button to turn it on. In AUTO mode, the system automatically adjusts the airflow and temperature, making it worry-free and efficient. I've noticed that some people mistakenly set the airflow too low or the direction incorrectly; adjusting the vents to the upper position works best. If the heating doesn't work after operation, it may be due to coolant leakage or a thermostat failure; checking the fluid level during regular maintenance can prevent dry running. The heating system is related to engine temperature management, and a malfunctioning system may affect fuel consumption. For long-term use, it's recommended to perform maintenance every six months.
