What does the ASR button on the VW jettas dashboard do?
The Anti Slip Regulator stops power to the wheels when they spin, The asr is designed to be turned off only when you require the wheels to spin at low speed EG: when you are on snow or ice – as the asr will stop the power to the wheels if they start spinning you would never get anywhere, Over 20mph the asr is not active and serves no function.
