Brake Assist System (BAS) and Anti-Slip Regulation (ASR) Fault Indicator

Brake Assist

Slip and Brake Fault IndicatorBrake Assist and Stability Control Fault IndicatorThe picture symbol, and the acronyms in the text fault symbol shown next to it, both mean Brake Assist System (BAS) and Electronic Anti-Slip Regulation (ASR), which is a Stability and Traction Control system. Any problem with the Brake Assist System shuts down the ASR, since ASR requires that all brake functions are operating properly for its own proper operation. The picture is of a tire with a double-ended arrow in it meant to suggest the tire and the vehicle it is attached to rolling or moving.

  • But first, is one of these truly your symbol?? If yes, then continue on below. 
  • Otherwise you can return to our main Picture Symbols page and scan again!

The Brake Assist system helps in emergency braking situations when the driver can’t push the brake pedal hard enough. A sensor recognizes the attempt at full braking and transmits the signal calling for full brake pressure from the hydraulic booster reducing the stopping distance.

Remember that these advanced systems come into play in extreme driving conditions, such as rounding a curve excessively fast. The brakes will continue to operate normally with the enhancements shut down. So, your vehicle is safe to drive under most normal conditions. Contact your dealer or authorized repair facility for repairs as soon as possible.

ESP / BAS IndicatorNote that BAS/ASR are essentially the same as ESP/BAS, but be aware of the acronyms. You can learn more about ESP/BAS here.
