These vehicles are equipped with an Antilock Brake System (ABS). The system employs a single valve per channel, 4-channel system to reduce the tendency of any wheel to lock-up. This improves driver control of the vehicle during braking. The purpose of the ABS is to minimize wheel lockup during heavy braking on most road surfaces. The ABS performs this function by monitoring the speed of each wheel and the ABS performs this function by controlling the brake fluid pressure to each wheel independently during a braking maneuver. This allows the driver to retain directional stability and allows the driver better steering capability.The purpose of the Antilock Brake System (ABS) is to minimize wheel slipping during braking, thus improving vehicle stability and steerability. The ABS accomplishes this objective by controlling the hydraulic pressure applied at each front wheel brake and both rear wheel brakes as a pair.The ABS operation is available from approximately 6.3 km/h (4 mph) to the maximum vehicle speed. During braking the ABS is available from the maximum vehicle speed to 5 km/h (3 mph).
