•  The hill launch assist (HLA) is a function which assists the driver in accelerating the vehicle on a slope by activating the linear control solenoid valve in the DSC HU/CM when the vehicle begins accelerating on a slope, and maintaining/reducing brake fluid pressure to prevent the vehicle from rolling for a specified time.

Note

•  The hill launch assist (HLA) operates on an up slope of approx. 3.5% or more (changes slightly depending on load and vehicle conditions such as tire wear and air pressure).

•  If the shift lever is in the R position, the hill launch assist (HLA) operates on a down slope of approx. 3.5% or more (changes slightly depending on load and vehicle conditions such as tire wear and air pressure).

•  The hill launch assist (HLA) operates constantly without affecting the DSC OFF switch operation.

•  When the parking brake is applied, the hill launch assist (HLA) does not operate.

•  When the DSC indicator light illuminates, the hill launch assist (HLA) does not operate.

•  The hill launch assist (HLA) constantly controls the brake fluid pressure in accelerating the vehicle on a slope by determining the hill launch assist (HLA) operation based on the signals input from each module via CAN communication, wheel speed signals from the ABS wheel-speed sensor, and the brake switch signal.
