How to Correctly Use Hill Start Assist in Automatic Transmission Vehicles?

[DaisyLee]

Automatic transmission hill start assist is correctly used as follows: 1. The gearshift lever is in any position other than P (for automatic transmission models); the accelerator pedal is not depressed; the vehicle is stationary; the parking brake is not engaged. 2. When these conditions are met, the driver removes their foot from the brake pedal, and the hill start assist system will activate; in some vehicles, the system automatically activates after the driver further depresses the brake pedal; additionally, this system also functions when reversing on a slope. 3. Extension: The car hill start assist is designed to prevent difficulty when starting on a slope. The hill start assist control temporarily (for up to about 3 seconds) applies braking to all four wheels to prevent the vehicle from rolling backward.
