ABS General System Description

This vehicle is equipped with the following systems:
- The Delco ABS VI Antilock Brake System (ABS)
- A Traction Control System (TCS) (if equipped) The ABS VI regulates the brake pressure as follows: Each of the front wheels
- Both rear wheels as a pair
The ABS VI regulates the brake pressure in order to reduce wheel lock-ups. Reduced wheel lock-ups improve the driver's control of the vehicle during braking.

Improved stability and steering enable greater control of the vehicle in the case of an abrupt stop.
The ABS operation is available from 5 km/h (3 mph) to the maximum vehicle speed.
The TCS is optional on the following models:
- The Chevrolet Venture
- The Pontiac Trans Sport
- The Oldsmobile Silhouette
The ABS and the TCS are part of the same hydraulic and electric system. The two systems use many of the same components. A problem in one of the two systems may disable the other system until the problem is repaired.
The antilock braking controls wheel slip during braking.
The Traction Control System (TCS) helps to control wheel spin at the driven wheels. Control of the wheel spin assists in maintaining vehicle stability and acceleration (drive traction) under changing road and vehicle load conditions.
