Is the Lexus ES rearview mirror heating automatically activated?

Lexus ES rearview mirror heating is automatically activated, but the owner must first set it to automatic mode. The setup method is as follows: 1. Start the car, then locate the rearview mirror heating module integration on the main driver's door panel; 2. Turn the rearview mirror heating switch downward for electric folding of the rearview mirror; 3. Turn the rearview mirror option to the heating position to set it to automatic mode for rearview mirror heating. Taking the Lexus ES 2020 300h Premium Edition as an example: The dimensions of this car are 4975mm in length, 1866mm in width, and 1447mm in height, with a wheelbase of 2870mm.
As an enthusiast who frequently researches new car technologies, I must say the Lexus ES's heated mirror function is typically not automatic. Many owners assume it activates automatically during rain, snow, or low temperatures, but it actually requires manual operation. For instance, while driving, there's a rear defroster button on the dashboard—pressing it not only clears the rear window fog but also activates the mirror heating. You need to remember this linked design. During my test drive of the latest ES model, I noticed the system only provides assistance in cold conditions, but core control remains manual. This is actually good because automatic modes sometimes misjudge situations and waste electricity. I recommend developing a habit of checking it after starting the car, especially during humid seasons, as keeping mirrors clear enhances lane-change safety and prevents blind-spot accidents. Additionally, consulting the owner's manual confirms specific operations, as different model years may vary—most post-2018 vehicles follow this manual setup. In short, don't rely on automation; proactive activation is key.
Having commuted with a Lexus ES for several years, my experience with the rearview mirror heating is that it's basically manual, not automatic. The most memorable moment was last winter during sleet when I forgot to press the button and could barely see the road conditions, almost causing an accident. Later, I learned my lesson and made it a habit to locate the wavy-line symbol control button (usually on the right side of the center console) every time I started the car. Pressing it activates heating for both the rearview mirror and rear window, clearing fog within minutes. This design is actually quite reasonable—it lets you fully balance energy efficiency and safety. If it were always automatic, the battery might be overused. Now when sharing with friends, I always remind them to develop this habit, especially during rainy season rush hours, as maintaining clear visibility reduces collision risks. Check your car—some driving mode settings might trigger semi-automatic activation, but most ES models require manual operation. Don’t slack off; practice a few times to get the hang of it.
