What does the LR button in the car mean?

[Margie]

LR button selects the left and right rearview mirrors. L stands for the left rearview mirror (first letter of 'left'), and R stands for the right rearview mirror (first letter of 'right'). The directional buttons adjust the rearview mirrors in four directions: up, down, left, and right. When in use, both left and right rearview mirrors will rotate simultaneously. The functions of the left and right rearview mirrors are introduced as follows: 1. Introduction one: The right rearview mirror can observe the vehicle and road conditions around the car body on one hand, and on the other hand, it can observe the situation of your own driving. 2. Introduction two: For left lane changing, just look at the left mirror. If you are overtaking a car on the left and merging in front of it, first look at your own side window, feel that you have passed the car on the left, then glance at the rearview mirror to confirm that the car appears in the mirror before changing lanes to the left. Right lane changing mainly also relies on the right rearview mirror to confirm the position of the car behind on the right. 3. Introduction three: Observing the rear when needing to change lanes to the right mainly also relies on the right rearview mirror to confirm the position of the car behind on the right. The specific position where the right rear car appears before changing lanes to the right may vary slightly for each car's rearview mirror, and can only be judged by habit. 4. Introduction four: Check the left and right rearview mirrors during emergency braking. When you see a situation ahead that requires emergency braking, while ensuring you can stop, observe if there is a car following closely behind in the rearview mirror. This way, you can appropriately ease the braking or consider changing lanes based on the distance ahead, leaving enough space for the car behind to avoid a chain-reaction collision.

I've always been fascinated by the little details in cars, like the LR button. This button, usually marked with the letters L and R, is specifically designed to control the position of the side mirrors. Pressing L adjusts the left mirror, and pressing R adjusts the right mirror. By turning the adjacent adjustment lever, you can change the angle of the mirrors. I always make it a habit to adjust them before driving to ensure clear visibility and avoid hidden blind spots. Thinking back to older cars without this feature, manually adjusting the mirrors was both laborious and imprecise. Now, electric controls make it so much easier. Especially on highways or in parking lots, precise visibility can prevent scrapes and collisions. I recommend that drivers check their side mirrors after adjusting their seats to ensure safe driving. Additionally, during rainy days or at night when visibility is poor, adjusting the mirrors properly can provide a fuller view of the lanes behind you. This small feature is worth paying attention to and learning how to use effectively.

After driving for so many years, I use that LR button every day. To put it simply, it's a selector—press L to lock the left mirror adjustment and R to lock the right, then use the directional buttons to adjust up, down, left, or right. This allows for quick adjustments before driving to ensure a clear view of blind spots when changing lanes or turning. I remember once at an intersection when I didn’t adjust it properly and almost missed a motorcycle coming from behind. Now, it’s a habit to press this button every time I start the car. Safety first—poor visibility can easily lead to accidents. Also, be careful not to let dust build up on the button, which could cause poor contact. Cleaning it occasionally can extend its lifespan. After replacing a mirror or adjusting the seat, always reset the angle. In short, small details matter—they can be a matter of life and death, so take them seriously.

As an ordinary car owner, I understand that the LR buttons on the car are switches for adjusting the rearview mirrors. Press the L button to select the left mirror for position adjustment, and press the R button for the right one, using the adjacent joystick to control the direction. This helps reduce blind spots and improves visibility of the surroundings when reversing or parallel parking. Personally, I find it simple and easy to use—just a quick adjustment before driving. If issues arise, such as button malfunction, it might be due to dirty wiring or a blown fuse, and a quick check by a technician should resolve it. Safe driving starts with the details.
