BMW 7 Series: Antilock Braking System ABS

Vehicle features and options

This chapter describes all standard, country-specific and optional features offered with the series.

It also describes features and functions that are not necessarily available in your vehicle, e.g., due to the selected options or country versions. This also applies to safety-related functions and systems.

When using these functions and systems, the applicable laws and regulations must be observed.

Antilock Braking System ABS

ABS prevents locking of the wheels during braking.

The vehicle maintains its steering power even during full brake applications, which increases the active safety.

ABS is operational every time you start the engine.

Brake assistant

When you apply the brakes rapidly, this system automatically boosts the vehicle braking capability to the furthest possible extent. It reduces the braking distance to a minimum during an emergency stop. This system utilizes all of the capabilities provided by the Antilock Brake System ABS.

Do not reduce the pressure on the brake pedal for the duration of the emergency stop.

Adaptive brake assistant

In combination with Active Cruise Control ACC, this system ensures that the brakes respond even more rapidly when braking in critical situations.

Drive-off assistant

Concept

This system supports driving off on uphill grades.

Driving off

  1. Hold the vehicle in place with the foot brake.
  2. Release the foot brake and drive off without delay.

After the foot brake is released, the vehicle is held in place for approx. 2 seconds.

Depending on the vehicle loading, the vehicle may roll back slightly.

DSC Dynamic Stability Control

Concept

Within the physical limits, the system helps to keep the vehicle on a steady course by reducing engine speed and by braking the individual wheels.

General information

DSC detects the following unstable driving conditions, for instance:

  • Fishtailing, which can lead to oversteering.
  • Loss of traction of the front wheels, which can lead to understeering.

Safety information

Warning


The system cannot serve as a substitute for the driver's personal judgment in assessing the traffic conditions. Based on the limits of the system, it cannot independently react to all traffic situations. There is a risk of accident. Adjust driving style to traffic conditions. Watch traffic closely and actively intervene where appropriate.

Warning


When driving with a roof load, for instance with roof-mounted luggage rack, the vehicle's center of gravity is higher, which increases the risk of the vehicle tipping in critical driving situations.

There may be a risk of accident or risk of damage to property. Do not deactivate DSC Dynamic Stability Control when driving with roof load.
