What Is The Tab Under Rear View Mirror For?

The tab under the rearview mirror serves a crucial purpose in enhancing driving safety and comfort. While it may seem like an inconspicuous feature, this tab plays a significant role in various aspects of driving.

1. Adjusting the Day/Night Setting

The primary function of the tab is to adjust the rearview mirror's day and night settings. During the day, the mirror surface reflects light, providing a clear view behind the vehicle. However, at night, the headlights of following vehicles can create glare that hinders visibility.

The tab allows you to flip the mirror surface to a night-time setting. This reduces glare by directing the reflected light downwards, preventing it from reaching your eyes.

2. Detecting Concealed Vehicles

The tab also acts as a visual cue to detect concealed vehicles in your blind spots. When you glance at the mirror, the tab's position can provide information about cars that may be lurking in your blind spot.

If the tab is visible in the mirror's field of view, it indicates that there is no vehicle in your blind spot. However, if the tab is hidden by another vehicle, it serves as a warning that you should proceed with caution and check your blind spot before changing lanes.

3. Preventing Mirror Sway

The tab plays a role in preventing the rearview mirror from swaying excessively. The tab acts as a stabilizer, holding the mirror firmly in place and reducing vibrations that could cause it to move or shake.

This stability is particularly important when driving on rough roads or in windy conditions, as it ensures that you have a clear and uninterrupted view behind your vehicle.

4. Accessing Hidden Features

Some vehicles incorporate additional features into the tab, such as built-in sensors or cameras. These features can enhance safety and convenience while driving.

For example, some vehicles have a tab that houses a rear-facing camera, which provides a wider field of view and helps you see potential obstacles when reversing.

5. Enhancing Interior Aesthetics

While the tab's primary purpose is functional, it can also contribute to the aesthetic appeal of your vehicle's interior. The tab's design and finish can complement the overall design of the dashboard and create a more cohesive and stylish look.
