The system allows you to better control the car during extreme driving and adapt it to your individual driving style.
However, this system does not replace the driver. It does not enhance the capabilities of the vehicle and should not encourage the driver to drive at a higher speed.
Even with this system, when driving a car, the driver must be careful and be attentive (the driver must be constantly prepared for any surprises that may arise while driving).
Operating principle
With the help of sensors installed on the wheels of the car, the system constantly measures and compares the speed of rotation of the drive wheels and monitors its sharp increase.
If the wheel begins to spin, the system brakes it, reducing the torque to a level that maintains wheel traction.
The system also controls the engine speed, maintaining it at a level that provides traction, regardless of the position of the accelerator pedal.

When the system is turned on, the control lamp starts flashing (see fig. 1.88).
System shutdown
In some cases (driving on very soft ground, snow, mud, and if snow chains are fitted) to reduce slippage, the system can reduce engine power. If it is not necessary to use the system, turn it off by pressing the switch.

Message «Traction control disabled» flashes and control lamps are on (pic. 1.89).
Disabling this feature also disables the ESP function.
As soon as possible, turn on the system by pressing the switch again.
The function will automatically turn on when the ignition is turned on or when the speed increases above 50 km/h (approximately).
At speeds above 50 km/h, this function cannot be disabled.
