How to Heat the Rearview Mirror on the Envision?
4 Answers
The rearview mirror heating button on the Envision shares the same button with the rear window defogger. Press it once to turn it on or off. The principle is actually very simple: an electric heating element (heating film) is installed inside the mirror lenses on both sides, which heats the rearview mirrors to evaporate moisture on the surface. Here is an introduction to rearview mirror heating: 1. The rearview mirror heating on the Envision is generally more practical in winter. In the morning during winter, you may notice frost on almost all the car's windows, which is difficult to wipe off with a towel. When the front windshield is frosted, you can turn on the heater after starting the car to blow warm air onto the glass to remove it. The frost on the rear windshield can be removed by turning on the rear window heating switch, which activates the heating wires inside the rear windshield. 2. During rainy or snowy weather, when the owner turns on the rearview mirror heating function, the heating element will quickly heat up to a fixed temperature within a few minutes, usually between 35-60 degrees Celsius, thereby heating the mirror and achieving the effect of defogging and defrosting.
As an average daily driver, I find the rearview mirror heating feature on the Envision incredibly simple and effective. Driving in the rain with foggy mirrors is downright dangerous, so I always remember the steps. After settling into the driver's seat, start the engine first, then locate the button with wavy lines or raindrop symbols on the center console—it's usually near the climate controls, next to the rear window defroster. A gentle press activates the indicator light, confirming the heating is on. Within minutes, fog or raindrops on the mirrors clear up completely. Pro tip: Use it with the engine running to avoid battery drain; the system typically auto-shuts to prevent damage if left on. I also test it before snowy winter days to ensure reliability. Remember not to use it unnecessarily on clear days to save power. This feature significantly boosts driving safety, especially on nighttime highways where clear visibility is critical.
I've been driving the Envision for several years, and the heated rearview mirror is one of my must-have features. On foggy days or after rain, activating it quickly clears the fog from the mirror: just press the button with the heat symbol on the control panel, usually located at the bottom left. Make sure the engine is running when operating it, otherwise the battery might struggle. The indicator light turning on confirms it's working properly, and the fog clears within minutes. Some models combine this button with rear window defrosting, but the Envision's dedicated button is much more convenient. I've also noticed it works better in cold weather. If it doesn't respond, first check the fuse or if the button has poor contact. Safety first—I always remind myself to turn it on before bad weather hits, adding an extra layer of security while driving. This feature is designed to be practical, requiring no complicated setup, making it perfect for lazy drivers.
When I take my kids to school in the Envision, the heated rearview mirror provides great peace of mind. On rainy days when the mirror fogs up, I just find the heating button on the console - the icon looks like a mirror with wavy lines. After starting the engine, I press it once until the light comes on. The whole process only takes a few seconds, and the kids don't even get fussy before the view clears up. I recommend using it only when needed, like on rainy or cold days, to avoid wasting electricity by leaving it on long-term. If the effect isn't noticeable, the button might be dirty or there could be a wiring issue - try a simple cleaning first. This feature is really thoughtful, saving the trouble of wiping the mirror.
