In the owners manual:
The VDC system uses an Active Brake Limited Slip (ABLS) function to improve vehicle traction. The ABLS system works when one of the driving wheels is spinning on a slippery surface. The ABLS system brakes the spinning wheel, which distributes the driving power to the other drive wheel. If the vehicle is operated with the VDC system turned off, all VDC system and TCS functions will be turned off. The ABLS system and ABS will still operate with the VDC system off. If the ABLS system or ABS is activated, the SLIP indicator light will blink and you may hear a clunk noise and/or feel a pulsation in the brake pedal. This is normal and is not an indication of a malfunction.
