Electric adjustment of the rearview mirrors is accomplished through the motor inside the mirror. This function is operated via buttons inside the car, and prolonged use will not cause damage to the mirrors. After adjusting the driver's seat, the ratio of sky to ground in the mirror is 1:1, allowing the rearview mirror to provide the widest possible field of vision. In narrow sections of the road, this can help avoid scratches, improving the vehicle's passability, and also reducing the space needed for parking.

I remember when driving my Volvo S90, adjusting the mirrors while on the move wasn't actually difficult, but extra caution was needed since distraction could easily lead to accidents. There's a dedicated adjustment area on the door panel, usually featuring a selector switch marked L and R—press it to choose the left or right mirror, then use the adjacent joystick to gently push and adjust the angle. After trying a few times, I found it quite user-friendly, though I never fiddle with it on highways—slowing down to a safe stretch before making adjustments is wiser. It's best to set them up before departure; the S90's mirrors are smartly designed with anti-glare features, so they don't need frequent adjustments during normal driving. If you must adjust while driving, pick an open road and don't take your eyes off the road for too long.

As a frequent driver, I find the mirror adjustment on the Volvo S90 very user-friendly. If you need to adjust while driving, there's a button system on the inner door: first press L for the left mirror or R for the right, then use the small knob to adjust the angle. But be careful – keep the movements quick and don't stare too closely while adjusting, as road conditions can change rapidly, and distraction could be dangerous. Personally, I recommend adjusting while parked for maximum safety, especially during the break-in period of a new car to familiarize yourself with the button locations. The S90's automatic adjustment feature is powerful—once set, it memorizes the position, making it hassle-free. Develop good driving habits by checking mirror positions before setting off to avoid last-minute adjustments.

Adjusting the rearview mirror while driving does pose risks, so I would prioritize finding a safe place to pull over first. The operation in the Volvo S90 is straightforward: use the door panel switch to select the left or right mirror, then adjust with the joystick. Making adjustments at high speeds increases the chance of errors—safety comes first. Once adjusted, visibility improves, but staying focused on driving is essential.
