Which Button is the Hill Start Assist?

The Hill Start Assist system in cars is typically integrated with the Electronic Stability Program (ESP). If the ESP on the vehicle remains activated, the Hill Start Assist function is also enabled by default. Below is an introduction to Hill Start Assist: 1. The Hill Start Assist system, abbreviated as HAC, is a function derived from the ESP system. It allows the vehicle to maintain braking for a few seconds after the driver's foot leaves the brake pedal when starting on a slope without using the handbrake. This enables the driver to easily move their foot from the brake pedal to the accelerator pedal, preventing the vehicle from rolling backward and causing an accident. 2. Hill Start Assist is specifically designed for starting on an uphill slope. Without Hill Start Assist, when starting on a slope and releasing the handbrake, the parking brake system disengages immediately. If the gear is not engaged, the vehicle may roll backward. Vehicles equipped with Hill Start Assist will delay the disengagement of the parking brake for about 2 seconds after releasing the handbrake, providing the driver with additional time to complete the starting process.
Hill Start Assist (HSA) doesn't usually have a dedicated button on most vehicles—it operates automatically via the car's sensors to detect gradients. For instance, after driving for over a decade, especially in mountainous areas, I've noticed that when stopping on a slope, the system automatically holds the brakes for 1-2 seconds after releasing the pedal. This allows smooth throttle application to start without rolling backward. The feature is typically integrated with the Electronic Stability Control (ESC) system, working alongside ABS and ESC modules without requiring any extra button presses. However, some models might have an optional toggle in the infotainment settings menu—Toyota or Ford SUVs occasionally offer standalone controls. It's wise to regularly inspect your brake system to ensure HSA functions properly; safety comes first, and this feature proves invaluable on steep inclines.
