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.
