: : All BMW 3 Series and Z3 models featuring DSC Dynamic Stability Control will also come with an integrated DBC and ADB function as of September 2000. In its operation and effects, the automatic differential lock acting on the rear wheels offers basically the same features as ADB-X on the all-wheel-drive models. But since in certain situations such as driving in deep snow or on loose ground, or when "rocking" the car out of deep soil or sand, intervention of the engine preventing the wheels from spinning may weaken the drive forces required, the driver is able in this case to deactivate the stabilising DSC function by briefly pressing the DSC button, switching over entirely to the ADB traction function. With road speed increasing, anti-spin control through engine management then helps to keep the car stable and under control. The driver is informed of this driving condition by the DSC telltale, and also has the option, as in the past, to de-activate the systems entirely by pressing the DSC button for a longer period.

: : DBC Dynamic Brake Control accelerates and reinforces the build-up of brake pressure when applying the brakes all-out, thus keeping stopping distances to a minimum even if the driver fails to press down the brake pedal with all his strength. Unlike other systems in the market, DBC uses a hydraulic brake pressure servo instead of a vacuum system. The big advantage of this hydraulic unit, which is part of the DSC system, is that full application of the brakes is much faster and better to control.
