Traction control system (ASR)

Functioning of the ASR system provides the increased course stability of the car at any high-speed modes and, besides, prevents pro-slipping of driving wheels at start-off from the place and sharp accelerations on a slippery paving.

The condition of ASR is controlled along with a condition of the amplifier of emergency brake application, the special control lamp of BAS/ASR warns about the revealed violations of the driver (see the Section Combination of Devices, measuring instruments and control lamps and light indicators).

In case of need the traction control system can be switched forcibly-off by means of the corresponding console switch (see the Section Governing bodies and the equipment of salon).

At the disconnected ASR system the precautionary control lamp which is built in assembly of a speedometer is activated (see the Section Combination of Devices, measuring instruments and control lamps and light indicators). Repeated activation of ASR is made by means of the same switch.

Maximum efficiency of action of ASR in winter season is reached at use of tires of the class M+S (for the movement on dirt and snow).

Use on the leading axis of tires of the different size leads to noticeable decrease in efficiency of return of the traction control system!

In case of refusal systems of anti-blocking of brakes (ABS) it is disconnected as well the traction control system.
