What is the difference between Hill Start Assist and Auto Hold?

[AlexanderFitz]

The differences between Hill Start Assist and Auto Hold: 1. Different functions: Hill Start Assist provides assistance when the vehicle is on an uphill slope; Auto Hold functions by automatically braking the vehicle when it comes to a stop without turning off the engine, allowing the vehicle to remain in a parked state. 2. Different usage methods: Hill Start Assist prevents the vehicle from rolling backward when the brake is released while in D gear on a slope, and it automatically disengages when the accelerator is pressed to move forward; Auto Hold activates when the vehicle is stopped and shifted into P gear, with the parking brake light automatically illuminating, eliminating the need to manually operate the handbrake button. Auto Hold essentially acts as if the brake is automatically engaged, maintaining parking brake force even after the brake pedal is released. This function is particularly useful on uphill and downhill slopes and during frequent starts and stops, such as when waiting at a traffic light, as it eliminates the need to use the handbrake or electronic parking brake, thereby simplifying operations.
