Which button is the hill start assist?

[MacLouis]

Car hill start assist system is usually integrated with the Electronic Stability Program (ESP). When ESP is turned on, the hill start assist remains enabled by default. The button varies across different car models. Hill start assist, abbreviated as HAC, allows the vehicle to maintain braking for a few seconds when starting on a slope without using the handbrake, even after the driver's right foot leaves the brake pedal. This makes it easier for the driver to move their foot from the brake pedal to the accelerator pedal, preventing rollback and potential accidents. Below are the conditions and methods for using hill start assist: 1. The gear lever is in any position except neutral (for manual transmission models); the gear lever is in any position except P (for automatic transmission models). 2. The car is stationary. 3. The accelerator pedal is not pressed. 4. The handbrake is not engaged. When these basic conditions are met, and the driver further presses the brake pedal while the vehicle is stopped, the hill start assist control is activated.
