  • Press button briefly (vehicles with Sport Chrono package: Press button for at least two seconds).
    PSM is switched off after a brief delay.
    The light indicator on the button and the PSM OFF warning light in the instrument panel come on.
    A warning appears on the multifunction display indicating that PSM is switched off.

Information
When braking in the ABS control range, the vehicle is stabilized even when PSM is switched off. Onesided spinning of the wheels is prevented even when PSM is switched off.


However, in exceptional situations it can be advantageous to temporarily switch off PSM:

  1. On loose ground and deep snow.
  2. When "rocking the vehicle free".

Information
When PSM Sport mode is active, it is only possible to switch to PSM OFF mode if the PSM was activated beforehand.


Switching PSM back on

  • Press button .
    PSM is immediately active.
    The light indicator on the button and the PSM OFF warning light on the instrument panel go out.
    A message appears on the multifunction display indicating that PSM is switched on.

ABS brake system (anti-lock braking system)

Loss of control of the vehicle
Despite the advantages of ABS, it is still the driver’s responsibility to adapt his driving style and driving maneuvers to the prevailing road and weather conditions, as well as the traffic situation.

The increased safety provided should not induce you to take greater risks with your safety. The limits set by the laws of driving physics cannot be overcome, even with ABS.

ABS does not reduce the risk of accidents owing to an inappropriate driving speed.


ABS ensures:

  1. Full steering control: Vehicle remains steerable.
  2. Good driving stability: No skidding due to locked wheels.
  3. Optimal braking distance: Shortening of braking distance in most cases.
  4. Prevention of wheel locking: No flat spots on the tires.

Function
The decisive advantage of ABS lies in the driving stability and maneuverability of the vehicle in hazardous situations.

ABS prevents the wheels from locking during full braking on virtually all road surfaces until just before the vehicles come to a standstill.

ABS begins to take control as soon as one wheel shows a tendency to lock.

The controlled braking process is comparable to cadence braking in very rapid succession.

The driver is warned to adapt the driving speed to the road conditions by a pulsing brake pedal and a "juddering noise".

Full braking is necessary:

  • Fully depress the brake pedal during the entire braking operation, despite the pulsing pedal. Do not reduce the braking pressure.

Multi-collision braking

During an accident, multi-collision braking can help the driver reduce the risk of skidding and further collisions during the accident through automatically initiated braking.

Prerequisites
Multi-collision braking works exclusively:

  1. During front, side, and rear-end collisions.
  2. When the airbag control unit detects an appropriate activation threshold during an accident.
  3. During an accident at a driving speed above approx. 5 mph (10 km/h).
