Attention! When checking the towing of a car with one of the axles off the ground, as well as when checking the effectiveness of the parking brake on the test stand, the engine must be turned off to avoid damage to the brake system as a result of the traction control system!
The operation of the ETS system provides increased directional stability of the car at any speed and, in addition, prevents slipping of the drive wheels when starting off and sharp accelerations on slippery road surfaces.
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, 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, control lamps and indicator lights).
By activating the LOW mode of the transfer case, the 4-ETS system is put into a special mode of operation that improves the reliability of traction control.
The maximum efficiency of 4-ETS in the winter season is achieved when using M + S class 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.
Note. In the event of a failure of the anti-lock brake system (ABS) the traction control system is also disabled, when the anti-skid system is disabled (see Section Electronic anti-skid system (ESP)) 4-ETS continues to function.
