How to Activate the Hill Start Assist on the Buick Envision?
2 Answers
Buick Envision's hill start assist does not have a specific switch; the system automatically engages. After coming to a complete stop on a slope, firmly press the brake pedal for more than two seconds to activate the system. At this point, releasing the brake will prevent the vehicle from rolling back. The Buick Envision comes standard with the HSA (Hill Start Assist) system across all trims, which prevents the vehicle from rolling backward when parking or starting on an incline. When the vehicle is braked to a stop on a slope, the HSA system intelligently activates. The Buick Envision measures 4694mm in length, 1839mm in width, and 1686mm in height, with a wheelbase of 2750mm. It delivers a maximum power output of 124kw and a maximum torque of 250nm.
When driving the Enclave, hill starts are the most dreaded scenario for rolling back. The hill start assist on this car is really reassuring. As long as you press the brake to stop the car on a slope and then release the brake, the system automatically engages, holding the car steady for two to three seconds without rolling back. This gives you enough time to switch your foot to the accelerator. It's important to note that the slope must meet the system's required angle to trigger the feature—it won't work on flat ground. Also, the brake pedal must be fully depressed; if only half-pressed, the system might not recognize it. I usually check the slope indicator in advance to confirm the assist is active before releasing the brake. This feature is especially useful in steep parking lots like those at shopping malls. New owners should practice a few times on a safe slope to get the hang of it.
