System of automatic stabilization of stability with the regulator of torque of the ASC+T/engine System of dynamic control of stability of DSC *


These systems increase stability of the movement, especially at start-off from the place, at accelerations, at change of conditions of coupling of tires with the road and on turns.
The DSC system expands advantages of ASC+T when passing turns. But the system is not able to ensure the safety which is going beyond physically possible.

The system joins after each start of the engine.

Special sensors determine angular speeds of wheels, and in the presence of the DSC system - also turn of wheels, cross accelerations, pressure of braking and the movement of the car of rather vertical axis.

If sensors define distinction in angular speeds of wheels, then the system draws a conclusion about emergence of danger of pro-slipping and reduces the moment directed to wheels. In addition to it if necessary the podtormazhivaniye of back wheels is made.

At recognition of unstable position of the car equipped with the DSC system for the purpose of stabilization perhaps also podtormazhivany forward wheels.

It is necessary to get used to such interventions of system. However similar intervention guarantees preservation of optimum traction effort at the best trajectory stability.

Podtormazhivaniye of wheels can be followed by noise.

Control lamp

The control lamp on the control panel dies away almost right after inclusion of ignition

Blinking of a control lamp:

The blinking means that the system regulates traction efforts, proceeding from the actual mode of the movement.

If the control lamp does not die away after start of the engine or lights up on the run, then it is a signal of malfunction of system if it, of course, was not disconnected earlier. However the car and without ASC+T/DSC * keeps the suitability to normal operation. Address the Section Diagnostics of Malfunctions.

Switching off of system

Press a key. The control lamp burns.

Depending on a car complete set the key has the inscription ASC+T or DSC. On an illustration the key arrangement at a full complete set is shown.
Depending on car complete set volume the arrangement can be other.

At the disconnected ASC+T/DSC system you move in the usual mode.

It is in exceptional cases expedient to disconnect system:

- at departure "vraskachka" or at start-off from the place in deep snow or on a friable surface.
- at the movement with antisliding chains, address the Section of Feature of driving of the car.

Repeated inclusion of system

Again press a key, the control lamp will go out.

The ASC+T/DSC systems cannot cancel operation of laws of physics. Therefore at excess of maximum permissible speed, a consequence of weak coupling of tires with a paving and influence of force of side withdrawal remain on conscience of the driver. Therefore avoid excessive risk, despite the increased safety potential.

For ensuring normal operability of system use tires only of one producer and with the identical drawing of a protector.
