Buick Enclave: Hill Start Assist (HSA)
This vehicle has a Hill Start Assist (HSA) feature, which may be useful when
the vehicle is stopped on a grade. This feature is designed to prevent the vehicle
from rolling, either forward or rearward, during vehicle drive off. After the driver
completely stops and holds the vehicle in a complete standstill on a grade, HSA
will be automatically activated. During the transition period between when the driver
releases the brake pedal and starts to accelerate to drive off on a grade, HSA holds
the braking pressure to ensure that there is no rolling.
The brakes will automatically release when the accelerator pedal is applied within
the two-second window. It will not activate if the vehicle is in a drive gear and
facing downhill or if the vehicle is facing uphill and in R (Reverse).
