The HLA prevents the vehicle from rolling backward or forward, such as when releasing the brake pedal while on a slope.
The HLA may not operate on a gentle slope or depending on the vehicle’s load.
The HLA does not operate if the parking brake is applied or the vehicle has not stopped completely.
When the TCS/DSC operation indicator light turns on, the HLA may not operate.
The HLA does not turn off even if the TCS is turned off.
