The steps to turn on the heater in a Lexus ES are: 1. Turn the temperature control switch to the red zone; 2. Turn on the external circulation and fan. Taking the 2020 Lexus ES as an example, it belongs to the mid-to-large-sized car category, with body dimensions of: length 4975mm, width 1866mm, height 1447mm, wheelbase of 2870mm, fuel tank capacity of 49.3l, and curb weight of 1720kg. The 2020 Lexus ES features a front MacPherson independent suspension and a rear multi-link independent suspension. It is equipped with a 2.5L naturally aspirated engine, delivering a maximum horsepower of 178ps, maximum power of 131kw, maximum torque of 221nm, paired with an electronic continuously variable transmission.
Starting the Lexus ES and turning on the heating is simple and enjoyable for me. After ignition, I press the AUTO button on the climate control panel to let the system operate automatically. Then, I rotate the temperature adjustment knob to the red zone or set it above 24°C, and warm air starts blowing immediately. If it's not warm enough, I increase the fan speed, but the ES's automatic climate control responds super quickly—usually, the cabin warms up within a minute or two. Remember to adjust the vent direction to avoid blowing directly at your face; pointing it toward your legs or the windshield ensures more even temperature distribution. During winter drives, I always prefer this setup—warm and comfortable, while also reducing fogging for safer long-distance trips. The heating works even better once the engine warms up, and operating it right after starting the car doesn’t affect fuel consumption over time. Once you get used to it, the ES's heating system becomes incredibly convenient to use.
To turn on the heating in a Lexus ES, here's what I do every time: Start the engine and ensure the car is running, then directly rotate the temperature knob in the air conditioning control area to around 28 degrees. Most ES models have an AUTO mode—just press it to automatically adjust the airflow, making it effortless. For more precise control, manually adjust the fan speed to a medium setting, and hot air will start blowing from the vents within minutes. On cold days, before using the heater, check that the engine temperature gauge has risen to normal levels—this ensures more effective heating and protects the AC components. Select recirculation mode to allow warm air to circulate quickly inside the cabin and prevent cold outside air from entering. These steps are simple and easy to learn. Once they become a habit, the ES heating system performs excellently with minimal energy consumption, ensuring a comfortable drive under your control.
