It also gave the Audi A4 the “Euro NCAP advanced” special award for its standard-fit multicollision brake assist system and for the Audi pre sense basic system, which is available as an option. Multicollision brake assist automatically brakes the Audi in the event of an accident, thus reducing the danger of skidding as well as the risk of further collisions. Audi pre sense basic tightens the seat belt in hazardous situations leading up to a collision, and closes the windows and sunroof.
Another key element of integral safety in the Audi A4 is the standard-fit assistance system Audi pre sense city – an anticipatory warning and emergency braking function. At speeds of up to 85 km/h (52.8 mph), the system checks whether there are other vehicles or pedestrians in the path of the car. If there is the risk of a collision it warns the driver according to a multi-stage concept: first visually and acoustically, then by a jolt of the brakes. Finally it triggers an automatic emergency brake application if need be.
There is also an array of other assistance systems to enhance safety in the Audi A4. These include collision avoidance assist, turn assist and the exit warning. While collision avoidance assist helps the driver to drive around an obstacle, turn assist monitors oncoming traffic when turning across the flow of traffic at low speed. In a dangerous situation, it brakes the A4 to a complete stop, if necessary, to prevent a turn when there is oncoming traffic. The exit warning minimizes the risk of injury when opening the doors. LEDs that light up red warn the occupants not to open the doors when other road users are approaching from behind.
