Brake Assist (BAS) can protect against accidents by identifying emergency braking situations based on the speed the brake pedal is depressed and then automatically building up full braking power.

The anti-lock braking system (ABS) then meters the braking power up to the slip threshold, which is how steering control is maintained. Once the driver releases the brake pedal, automatic brake boosting is immediately terminated.

The electronic parking aid PARKTRONIC monitors the front and rear of the vehicle during manoeuvring and warns the driver when it detects a potential collision.

Operating at speeds between 30 and 250 km/h, Active Blind Spot Assist monitors the area behind the vehicle as well as to the left and right. If a vehicle is detected in the monitored area, a warning signal appears in the relevant exterior mirror.

If the driver then operates the indicator, an additional audible warning is sounded. This also happens if vehicles move from two lanes away into the lane alongside the driver.
