Collision response
Tip
Before
Before an impact, several driver support functions can work to avoid the collision or reduce its effects. If the car perceives a collision to be likely or unavoidable, it has the ability to pre-emptively activate protective systems, such as seatbelt pretensioning, before the impact occurs.
During
During the collision, sensors throughout the car continuously provide information about the states of the car and its occupants. The car uses the information to selectively time and activate protective functions such as airbag deployment and seatbelt pretensioning. Collisions are complex events that can unfold in several stages, where the first impact isn't necessarily the most severe. Good timing is essential for the best chance of effective protection.
The car's safety systems work in synergy with passive safety features. In the event of a collision, your car's construction distributes forces to specific structural components. It also takes advantage of crumple zones that absorb energy from the impact. Using similar principles, the exterior has been designed with the protection of pedestrians in mind.
After
After a collision, the car tries to stop in a controlled and safe manner. It can also make an automated call for emergency response.
Note
Safety mode
During a collision, the safety systems of the car may disconnect the high-voltage battery. This is to protect both the occupants and the car itself from potential damage caused by the battery. At the same time, the car enters safety mode. When safety mode is active, you cannot drive the car. However, depending on the severity of the collision, you can exit safety mode via the centre display if you need to move the car out of immediate danger. This in turn reconnects the high-voltage battery and enables short distance driving.
