Car rearview mirrors do not open automatically. Here is detailed information about car rearview mirrors: 1. Overview: Car rearview mirrors are located on the left and right sides of the car's front and inside the car. They reflect the situation behind, beside, and below the car, allowing the driver to indirectly see these areas. They act as a "second pair of eyes," expanding the driver's field of vision. 2. Precautions: Car rearview mirrors are important safety components, and their mirror surface, shape, and operation are carefully designed. The quality and installation of rearview mirrors are subject to corresponding industry standards and cannot be altered arbitrarily.

The car I drive has the automatic folding and unfolding side mirror function. Every time I unlock it with the key, the side mirrors slowly unfold themselves, and they automatically retract when locking the car. This feature is called power-folding mirrors in the manual, and it's equipped in many mid-to-high-end vehicles. What I like most is its usefulness when parking in narrow spaces—folding the mirrors prevents them from being scraped by other cars. However, in winter, you need to be careful. If the mirrors are frozen, forcing them to unfold might damage the motor. I encountered this issue once, but it was fine after removing the ice before operation. Some cars can also be set to automatically tilt the right-side mirror when shifting into reverse gear, which works particularly well with the automatic unfolding feature.

My car has the auto-folding feature, but not all vehicles come with it. You can first check if there's a button with a folding icon on the driver's side door panel - if present, it indicates electric operation. Typically, holding the unlock button on the car key for 3 seconds will unfold the mirrors, and they'll automatically fold when locking the car. Retrofitting costs around 800 RMB, but I don't recommend aftermarket modifications since it involves wiring alterations. A friend's car once experienced window control failure after such installation - factory-equipped features are always more reliable. Also note that frequent automatic unfolding may shorten motor lifespan; manual operation is more economical when parking in spacious spots.

I was also curious about this when I first bought my car. With my current vehicle, as long as I enable the auto-folding feature in the vehicle settings, the mirrors automatically fold in when locking and unfold when unlocking. It's especially convenient in rainy weather since folded mirrors reduce water accumulation. However, once during a car wash, the automatic unfolding feature got a hose stuck, and the technician advised manually disabling this function before washing. If your car doesn't have this feature, you might try holding down the unlock button on the key fob—some cars have this as a hidden function.

As someone who frequently interacts with various car models, I've noticed that the automatic side mirror function comes in three tiers: entry-level cars require manual adjustment, mid-range models feature button controls, and only premium models support automatic folding/unfolding upon locking. The core of this function lies in the miniature motor at the base of the mirror, costing approximately 300 yuan per unit. Common malfunctions include unusual noises during folding or jamming, mostly caused by dust accumulation on the tracks or gear wear. Specialized lubricant must be used during repairs, as regular grease can corrode plastic components. Some owners also report automatic unfolding failures in winter, often due to short circuits caused by moisture in wiring connectors.
