BMW 3: Anti-lock Braking System ABS
ABS prevents locking of the wheels during braking.
The vehicle maintains 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 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, 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 or when a trailer is used, the vehicle may roll back slightly.
