This system improves driving stability, especially when accelerating and cornering.
Traction control ASC+T prevents wheel spin and ensures the best possible driving stability.
Sensors on the wheels determine from the angular velocity. On this basis, the control system concludes that the drive wheels are slipping. Depending on the road conditions, two adjustment mechanisms are used. With a large excess of power and. consequently, the slipping of the drive wheels reduces the engine torque. In addition to this, and without driver intervention, the slipping drive wheel is automatically braked. This achieves an effect comparable to that of an adjustable self-locking differential. Such braking is possible at speeds up to 40 km / h. At speeds above 40 km/h, but not more than 100 km/h, a lower intensity braking is used to increase traction.
The system is activated after each engine start.
The control lamp on the instrument panel goes out some time after the ignition is switched on (refer to Section 1).
System shutdown
Press a key. At the same time, the control lamp will light up.
Switching the system back on
Press the key again. The control lamp will go out.
Flashing control lamp
Flashing indicates that the system is adjusting traction based on the Actual Driving Mode.
If the control lamp does not go out after starting the engine or lights up on the go, then this is a signal of a system malfunction. However, a vehicle without ASC+T retains its suitability for normal use. For repairs, contact a BMW workshop.
