What are the functions of the GL8 interior rearview mirror?

The Buick GL8 interior rearview mirror is primarily designed to facilitate observation of the rear seats and the area behind the vehicle. The adjustment controls for the GL8 rearview mirror are located on the door armrest. To adjust the left and right rearview mirrors, first press the corresponding mirror selection control button, after which you can adjust the mirrors up, down, left, or right. Buick GL8 rearview mirror heating: The rearview mirror heating function shares the same button with the rear window defroster. Pressing this button activates the heating function for the rearview mirrors. Typically, during rainy or foggy weather, heating the mirrors can improve their clarity. Buick GL8 rearview mirror folding: The rearview mirror folding button is located on the door armrest. Pressing this switch automatically retracts the mirrors. Additionally, some models can be configured to automatically fold the mirrors when the vehicle is locked. Correct adjustment angles for rearview mirrors: Adjust the center rearview mirror so that it is parallel to the horizon, with the horizon positioned at the center of the mirror's surface, occupying the middle 1/2 of the mirror. To ensure a clear view of the road behind, the mirror can be slightly angled toward the driver. For the left rearview mirror, which is particularly important due to the driver's position on the left side of the cabin, it is recommended to adjust the mirror so that the car's body occupies 1/4 of the mirror's surface and the horizon occupies 1/2. This adjustment allows the driver to see the following vehicle closely behind, as well as vehicles in adjacent lanes, aiding in driving judgment.

I often use the GL8 to pick up and drop off my kids at school. Its interior rearview mirror actually has some thoughtful features. The most commonly used one is the auto-dimming function, which prevents glare from bright headlights behind at night. The built-in dashcam is also quite practical—just press a button to record road conditions. I particularly like its compass design, which helps me avoid getting lost in unfamiliar places. There's a small button below the mirror to control the reading light, so I don’t have to fumble around the ceiling. I’ve heard that higher trim levels come with a streaming media feature, allowing rear passengers to view navigation, but my model doesn’t have it. The mirror adjusts angles very smoothly, providing a stable view of the rear during turns, though the plastic frame tends to collect fingerprints and requires frequent cleaning.

The anti-glare function of the rearview mirror in the GL8 has genuinely saved me several times during long-distance drives. It automatically dims when sensing strong light from vehicles behind, unlike older cars that require manual adjustment. Once during heavy rain, ordinary mirrors couldn't clearly show the vehicles behind, but its hydrophobic coating prevented water droplets from forming, maintaining a clear view. The built-in dashcam hidden below is essential for highway driving, providing evidence in case of accidents and supporting loop recording without consuming too much memory. The rearview mirror also displays a height reminder for the trunk, eliminating worries about hitting objects while reversing. However, prolonged use of this function can cause overheating, so ventilation is necessary in summer. These designs truly enhance the driving experience.

The GL8's rearview mirror is more than just a mirror; it integrates numerous smart features. Anti-glare is a standard configuration, where the mirror automatically darkens in strong light to ensure clear visibility. It also comes with a hidden dashcam that can be operated directly on the mirror for recording. The built-in temperature and compass display is particularly suitable for camping trips, allowing you to navigate without checking your phone. Some owners have modified it with a streaming rearview mirror, which significantly improves nighttime visibility. However, cleaning this mirror can be troublesome, as dust tends to accumulate in the corners and requires frequent maintenance.
