4 Answers
Here's how to turn on the heater in Dongfeng Nissan Sylphy: 1. When the A/C indicator light is on, press the A/C button to turn off the cooling switch. 2. Rotate the temperature control dial to the red zone. The temperature adjustment range is 18~32°C. Do not set the temperature lower than the outside temperature, as this may prevent proper temperature control. 3. Turn the fan speed switch to adjust the appropriate airflow speed. 4. The choice between internal and external air circulation depends on the driving environment: use external circulation when air quality is good, and internal circulation when it's poor. External circulation ensures better air quality inside the car, while internal circulation provides better heating efficiency.
As a long-time owner of a Nissan Sylphy, I often help friends with how to turn on the heater. After starting the engine, you'll see a temperature control knob on the center console. Turn it clockwise to the red zone to begin heating. If you want to warm up the car quickly, press the AUTO button on the AC, which automatically adjusts the fan speed and temperature, making it hassle-free and comfortable. Remember to warm up the engine for 1-2 minutes before driving in winter to ensure normal engine temperature and better heating performance. Don’t worry about fuel consumption—using the heater at steady speeds can actually save energy since it utilizes engine waste heat. If the airflow is weak, check if the vents are adjusted correctly; pointing them toward yourself and passengers will make it warmer. The heater is crucial in cold weather to prevent window fogging and ensure safer driving.
Having worked on cars for many years, I find it quite simple to turn on the heater in a Dongfeng Nissan Sylphy: after starting the engine, just turn the temperature knob to the high setting, which is marked with red. Then adjust the fan speed knob to your comfort level. Be careful not to turn the fan to maximum right away to avoid blowing cold air before the engine warms up. It's best to let the engine idle for a minute or two before adjusting. The heating system relies on the engine coolant for warmth, so regularly check the coolant level in the radiator—low levels mean no heat. If it never feels warm enough, check if the recirculation switch is off; keeping the air circulating inside the car is more efficient. This habit can save you money by reducing frequent trips to the repair shop.
A friend asked me how to turn on the heater in a Nissan Sylphy, and I said: Start the car, turn the temperature dial to the hot zone, choose a fan speed, and you're done. For the automatic version, just press the AUTO button and set the temperature. It's that simple, don't overthink it.
