The button on the top of the turn signal lever is used to activate the driving assistance system. Here is a detailed introduction to the driving assistance system: Overview: The driving assistance system includes the lane keeping assist system, automatic parking assist system, brake assist system, reverse assist system, and driving assist system. The lane keeping assist system provides support for maintaining the lane while driving. It uses a camera to identify the lane markings. Others: The reverse assist system informs the driver of the relative position between the car and obstacles in an intuitive form of images and sounds, eliminating the trouble caused by blind spots in the rearview mirror, thus providing convenience for the driver when reversing and parking, and eliminating potential safety hazards.
When I first started driving, I was particularly curious about the small button at the top of the turn signal stalk. Later, I learned that it was the switch button controlling the turn signals. Pressing it activates the left or right turn signals or the hazard warning lights, which is especially crucial when changing lanes or making turns. Once during practice, I accidentally pressed it too late and almost forgot to signal, but thankfully corrected it in time. This design is simple and easy to operate, with most modern cars integrating it into the stalk—just a light press is needed, avoiding complex operations that could distract. I recommend new drivers practice using it more to develop the habit, as light signals are particularly important for alerting vehicles behind in rainy or foggy conditions. If the button isn’t responsive, it might be due to aging wiring or contact point issues, so a visit to the repair shop is necessary—don’t ignore it. In short, this is a daily small tool that ensures driving safety, and everyone should take it seriously.
