ABS The Anti-Lock Brake System (ABS) controls the hydraulic brake pressure of all four wheels during sudden braking and braking on hazardous road surfaces, preventing the wheels from locking. The ABS provides the following benefits: (1) Enables steering around obstacles with a greater degree of certainty during panic braking. (2) Enables stopping during panic braking while allowing stability and control, even on curves. In case a malfunction occurs in the anti-lock brake system, the system will operate as a normal brake (fail safe mode). A diagnosis function and fail-safe system have been included for serviceability.
