The system is activated automatically when the car is moving at speeds from 40 to 80 km/h.
The functioning of the ETS is monitored simultaneously with the state of the anti-skid system (ESP), - a dangerous decrease in the coefficient of adhesion of tires to the road surface is warned by the activation of a lamp in the flashing special control lamp 4-ETS / ESP (see Section Instrument cluster, meters and control lamps and indicator lights).
If malfunctions are detected in the traction control system, the 4-ETS warning lamp is activated (see Section Instrument cluster, meters and control lamps and indicator lights).
When the LOW RANGE mode is activated for off-road driving, the 4-ETS system is put into a special mode of operation, which provides increased reliability of traction control.
The maximum effectiveness of the ASR in the winter season is achieved with the use of class M + S tires (for mud and snow).
Attention! The use of tires of different sizes on the drive axle leads to a noticeable decrease in the effectiveness of the traction control system!
Note. In the event of a high brake load, the 4-ETS system is automatically switched off for a short time to prevent overheating of the brakes - this switch-off is accompanied by the activation of the warning lamp.
In the event of a failure of the anti-lock brake system (ABS) the traction control system is also disabled.
