The Roewe i5 is equipped with a heated rearview mirror function. The switch for the heated rearview mirror is located on the center console, next to the front windshield defogger switch, and is marked with an icon featuring three curved upward arrows alongside a rectangle. The heated rearview mirror is particularly useful during rainy or snowy weather. When activated, the heater behind the mirror quickly warms the mirror surface, gradually removing rain or fog, eliminating the need for the driver to manually wipe the mirror frequently, thereby reducing driving hazards. How to use the heated rearview mirror function: There are generally two ways to activate the heated rearview mirror function. One is combined with the electric rearview mirror adjustment button—simply rotate the knob to turn it on. The other is located on the air conditioning control panel—press the heating button to activate it. No manual angle adjustment is needed, as there is an adjustment button on the driver's side. Principle of the heated rearview mirror function: After pressing the button, the electric heater behind the rearview mirror glass rapidly heats up to a fixed temperature within minutes, typically between 35-60 degrees Celsius. Heat is then emitted from both left and right rearview mirrors. Simultaneously, as the temperature rises and evaporation occurs, water droplets on the mirror surface become smaller, and fog gradually dissipates, effectively heating the mirror and removing frost. However, if the rain is particularly heavy, the effect may diminish and become less noticeable. Precautions for using the heated rearview mirror function: The principle of the heated rearview mirror involves adding electric heating wires to the mirror, which consume a significant amount of power. When using this function, ensure the car is in an active state (engine running). Avoid activating the heated rearview mirror when the car is stationary to prevent draining the car , which could then fail to provide sufficient power for starting the vehicle. Other methods for defogging the rearview mirror include: Opening windows for air circulation: Crack open the side windows slightly to create airflow between the inside and outside of the car, reducing the temperature difference and allowing the fog to dissipate gradually. Adjusting the car's air conditioning to the appropriate setting can also help defog the mirror by blowing warm air.

I drive a 2021 Roewe i5 Automatic Diamond Edition, which indeed comes with heated mirrors. However, this feature might not be available in lower trim models. Last week during rain, I experienced its practicality firsthand—just press that rectangular button with wavy arrows on the center console, and within five minutes, the water droplets on the mirrors evaporated completely. Much safer than wiping with tissues! I heard it works on the principle of electric heating wires and can even prevent frost in winter. If a used car, always verify if it's an original factory feature—retrofitting can easily lead to water leakage. My friend’s aftermarket modification caused fogging in just three months. If your budget allows, go for the higher trim with heating pre-installed—rainy-day driving safety is too crucial.

Recently, while studying the Roewe i5 configuration manual, I noticed that the rearview mirror heating is only available on certain higher-end models, such as the 1.5L automatic Langhao version and above, where it comes as standard. The activation method is very simple: after starting the engine, press the square icon button on the central control panel, and the indicator light will turn on, signaling that it's working. This feature is especially suitable for the rainy season in southern regions, as it defogs faster than the air conditioning. It also works in conjunction with the rear window defogger, and the manual states that it performs best when the temperature is below 15 degrees Celsius. It's important to check whether the window anti-pinch and electric folding functions are fully equipped, as these are all part of the same wiring system as the heating module.

The heated mirrors on the Roewe i5 are achieved through heating wires on the back of the mirror glass, and this feature is indeed available in higher trim models. Tests show that it can melt ice in just ten minutes when activated at zero degrees, making it safer than pouring hot water. It's important to note that using the heating function during rainy seasons can accelerate drain, so it's recommended to use it in conjunction with the engine start-stop system. The original factory-coated mirror glass is less prone to yellowing when heated, whereas aftermarket parts from modification shops may become blurry after just six months. This feature is particularly worth opting for by owners in northern regions, as the clarity of mirrors on icy roads directly impacts lane-changing safety.

When accompanying my friend for a test drive of the Roewe i5, we specifically tested the rearview mirror heating function. The salesperson mentioned that versions with a panoramic sunroof generally come equipped with it. The operation is quite intuitive—just locate the square button with a steam-like pattern in the middle of the air conditioning panel. On a cloudy day, it took about three minutes to noticeably remove water mist, but for rainy conditions, it's recommended to use rain repellent for longer-lasting effects. A handy tip: closing the windows while using the heating function can reduce moisture condensation. The modification cost is approximately 800 yuan, but it might affect the vehicle's electrical circuit warranty.

Driving the Roewe i5 in rainy days, I'm most satisfied with its rearview mirror heating function. My luxury version comes with automatic wipers and this feature. After pressing the button, the mirror temperature can rise to about 50 degrees, quickly turning water droplets into steam. I remember one time during a heavy rainstorm on the highway, without heating, the rearview mirror was completely unclear—now there's no need to worry at all. It's recommended to tell the car wash staff not to directly spray high-pressure water at the heating area during cleaning, as it can easily cause the sealing strip to age and leak. In winter, wait two minutes after starting the vehicle before turning on the heating, which is more -friendly.
