Driving Stability Control Systems

Vehicle features and options

This chapter describes all standard, country-specific and optional features offered with the series. It also describes features that are not necessarily available in your car, e.g., due to the selected options or country versions. This also applies to safety-related functions and systems. The respectively applicable country provisions must be observed when using the respective features and systems.

Antilock Brake System ABS

ABS prevents locking of the wheels during braking. The vehicle retains its steering power even during full brake applications, thus increasing active safety. ABS is operational every time you start the engine.

Brake assistant

When you apply the brakes rapidly, this system automatically produces the greatest possible braking force boost. It reduces the braking distance to a minimum during an emergency stop. This system utilizes all of the benefits provided by ABS. Do not reduce the pressure on the brake pedal for the duration of the emergency stop.

DSC Dynamic Stability Control

DSC prevents traction loss in the power wheels when driving off and accelerating. DSC also recognizes unstable vehicle conditions such as fishtailing or nose-diving. Within the physical limits, DSC helps to keep the vehicle on a steady course by reducing engine speed and applying brakes to individual wheels.

Note

Adjust your driving style to the situation. An appropriate driving style is always the responsibility of the driver. The laws of physics cannot be repealed, not even with DSC. Therefore, do not reduce the additional safety margin by driving in a risky manner.

Do not deactivate DSC when driving with roof load

Do not deactivate Dynamic Stability Control (DSC) when driving with roof load, e.g., roof-mounted luggage rack. Otherwise, driving safety is not ensured in driving-critical situations due to the elevated center of gravity.

Overview

Button in the vehicle: DSC OFF button

Indicator/warning lights

  • The indicator lamp flashes: DSC controls the drive and braking forces.
  • The indicator lamp lights up: DSC has failed.

Deactivating DSC: DSC OFF

When DSC is deactivated, driving stability is reduced during acceleration and when driving in curves. To increase vehicle stability, activate DSC again as soon as possible.

Press and hold the DSC OFF button for up to approx. 10 seconds until the indicator lamp for DSC OFF lights up in the instrument cluster. The DSC system is switched off, and the steering and, depending on the equipment, suspension are tuned for sporty driving.

Activating DSC

Press the DSC OFF button. DSC OFF and the DSC OFF indicator lamp go out.

DTC Dynamic Traction Control

The DTC system is a version of the DSC where forward momentum is optimized. The system ensures maximum headway on special road conditions or loose road surfaces, e.g., unplowed snowy roads, but with somewhat limited driving stability. Activating DTC provides maximum traction, but driving stability is limited during acceleration and when driving in curves.

When to use DTC

  • When driving in slush or on uncleared, snow-covered roads.
  • When freeing the vehicle from deep snow or driving off from loose grounds.
  • When driving with snow chains.

Activating/Deactivating DTC

Press the button to activate DTC. "TRACTION" is displayed in the instrument cluster, and the indicator lamp for DSC OFF lights up. Press the button again to deactivate DTC; "TRACTION" and the DSC OFF indicator lamp go out.

Performance Control

Performance Control enhances the agility of the vehicle. To increase maneuverability with a sporty driving style, wheels are braked individually. The resulting braking power is largely compensated simultaneously by an engine intervention.
