The ABS is a brake system which controls the wheel cylinder hydraulic pressure of all four wheels during sudden braking and braking on slippery road surfaces, prevent the wheels from locking. This ABS provides the following benefits:
- Enables steering round an obstacle with a greater degree of certainty even when panic braking.
- Enables stopping in a panic brake while keeping effect upon stability and steerability to a minimum, even on curves.
The function of the ABS is to help maintain directional stability and vehicle steerabilty on most road surface conditions. However, the system cannot prevent the vehicle from skidding if the cornering speed limit is exceeded.
The ABS has a longitudinal sensor to match braking characteristics to the full-time four wheel drive on 4WD models.
In case a malfunction occurs, a diagnosis function and fail-safe system have been adopted for the ABS to increase serviceability.
