MODEL3's hazard warning button is located on the ceiling of the front cabin, between the main driver's illumination light and the co-driver's illumination light. In fact, Tesla's design is very scientific, because if the hazard warning light is also integrated into the central control screen, in case the central control screen fails or the vehicle runs out of power, the hazard warning light function will undoubtedly be unusable. Placing the hazard warning button on the ceiling is both aesthetically pleasing and convenient. Here is an introduction to Model3: 1. Model3's timeline: Model3 is a new car launched by Tesla in 2017, not a scaled-down version of ModelS, but built on a brand-new platform. 2. Model3's specifications: Model3 belongs to the Tesla ModelX series, with a body length of 4694mm, standard seating capacity of 5, luggage compartment volume of 396 liters, and available body colors: silver, black, and blue, equipped with Ludicrous mode.

I've been driving the Model 3 for two years, and the hazard light switch is placed in the most prominent spot right overhead. Just look above the interior rearview mirror, and you'll find a physical button with a red triangle symbol that works regardless of whether the screen freezes. I remember last year during heavy rain on the highway when Autopilot suddenly disengaged—I instantly pressed that triangle button, and the trailing vehicles could see the warning from far away. It's also super convenient for temporary roadside parking; a light tap turns the lights on, and another press turns them off. Compared to searching for a tiny button on the dashboard in old gas cars, this design is genuinely intuitive and safe.

When learning to drive, the instructor taught: in any dangerous situation, turn on the hazard lights first. The Model 3's hazard light button is located directly above the rearview mirror inside the car, with a red label that is very eye-catching. Last week, while accompanying a friend to pick up a new car, I noticed a detail: the start button requires pressing the brake, but the hazard light button can be used at any time, operating on a completely independent circuit. Once, when the car in front suddenly braked at an intersection, I almost hit the hazard lights by muscle memory. It's recommended for new car owners to set their parking contact number and hazard light location as their phone's lock screen wallpaper—it could be a lifesaver in an emergency.

As a product experience specialist, I must say that placing the hazard lights in the overhead light panel of the Model 3 was a well-considered decision. The hazard lights automatically activate when airbags deploy, and the manual button features raised texture to prevent accidental presses. During one test, we discovered that even with the vehicle completely powered off, the hazard lights could still be activated using the emergency power supply. Although there's a virtual button on the central touchscreen, the physical button responds 0.3 seconds faster – this is what truly constitutes a safety redundancy design.

Having repaired electric vehicles for ten years, Tesla's hazard light circuit is the most reliable. The Model 3's physical button is directly connected to the fuse box, bypassing the mainboard. Here are two tips: ① If trapped in the car during heavy rain, long-pressing the hazard light can trigger an SOS call for help. ② Do not turn off the hazard lights after a rear-end collision, as repair shops need to read the fault codes. The recent facelift increased the button backlight brightness by 25%, making it easier to locate at night.

Model 3 veteran owner shares cool tips: The hazard light button serves more than just warning purposes. When camping, double-clicking it can up the low-voltage system to charge external devices; when the car key runs out of battery, pressing the key against it can wake up the vehicle; even when system updates fail, pressing it five times in a row enters engineering mode. That red triangle icon hides more functions than the manual, though its most frequent daily use remains instantly activating warnings during sudden tire blowouts.
