The method to use the rearview mirror heating function on the Sagitar is as follows: Power on the vehicle, then directly press the rearview mirror heating button located in the air conditioning control area. The button features a rectangular frame with three curved lines running from the bottom to the top. When this function is activated, the rear window defogging function will also be enabled simultaneously. Taking the 2021 Sagitar 200TSI Manual Fashion Smart Connect Edition as an example, it adopts a turbocharged intake system, belongs to the compact car category, delivers a maximum horsepower of 116ps, and a peak torque of 175nm. The dimensions of the 2021 Sagitar 200TSI Manual Fashion Smart Connect Edition are 4753mm in length, 1800mm in width, and 1462mm in height, with a wheelbase of 2731mm.

I've been driving a Volkswagen Sagitar for several years, and the rearview mirror heating function is particularly useful in rainy or snowy weather. The operation is very simple: sit in the driver's seat and locate the rearview mirror adjustment knob on the door panel, usually a round button with directional markings. Rotate it to the heating icon position—the icon looks like wavy lines or a thermometer, which is the heating activation point. Once pressed, the current will heat the mirror to defog or defrost it, and the effect is quite fast, taking about 5 to 10 minutes for the mirror surface to clear up. Remember to turn it off after use, or it will automatically stop to prevent wasting battery power. This function can improve visibility in harsh weather and reduce the risk of collisions. I use it frequently during northern winters—when the mirror heats up, the ice melts quickly, making driving safer and more worry-free. Remember to regularly check if the knob operates smoothly; if there are any issues, take it to the 4S shop for maintenance to ensure the function remains reliable.

As an automotive technology enthusiast, I have some understanding of the mechanism behind the Sagitar's rearview mirror heating. It utilizes built-in heating wires to warm the mirror surface for defogging purposes. To activate, locate the mirror adjustment knob in the middle of the driver's side door panel and rotate it to the heating position, which triggers the circuit. This function works most effectively when temperatures are below 10°C, quickly evaporating moisture. The system automatically shuts off after a set duration to prevent damage - it's recommended to use only during rainy, foggy, or frosty conditions. Avoid prolonged usage to prevent battery drain or circuit overload. The Sagitar's design often integrates rear window defogging for convenient one-touch dehumidification. Regularly checking button responsiveness can extend service life, and verifying mirror integrity before each operation ensures safer usage.

As a newbie driving a Sagitar, the rearview mirror heating has been a great help on rainy days. Just find the adjustment knob inside the door handle, turn it to the heating icon position, and wait for the mirror to dry. When rain causes fogging, it keeps the mirror surface clear, making it easy to see the traffic behind without blurriness. Safety is crucial—don't take risks on the road. It's simple to operate with just a few steps. Use it less when the weather warms up to save resources. This small feature offers high practical value.
