The Automatic Stability Regulation (ASR) system is a component of the Electronic Stability Program (ESP). In unfavourable road conditions, the Automatic Stability Regulation (ASR) system makes starting off, accelerating and driving uphill much easier, or even possible, in general.
ASR operates automatically, i.e. without driver intervention. Using ABS sensors, the device monitors the rotation speed of the drive wheels. When the wheels slip, the engine speed is reduced, thereby adjusting the traction force to the road conditions. The device operates in the entire speed range.
ASR works together with ABS. If ABS fails, ASR will not work either.
Note: A prerequisite for the smooth operation of ASR is the installation of identical tires on all four wheels of the vehicle. Different tires may lead to an undesirable reduction in engine power.
