Pre sense side (to be introduced at a later date)
Audi pre sense side can initiate measures for the protection of the vehicle occupants in the event of a side-on collision
with another vehicle.
In models equipped with Audi pre sense side, the following actions can be initiated:
› Raising of the vehicle ride-height in the event of an
imminent side-on impact on the collision-facing side. In
this way, the forces occurring during a collision can be
redirected toward crash-active body structures.
› Full tensioning of the electrically reversible seat belt
tensioners.
› Closing of the side windows apart from a residual gap.
› Closing the panoramic sunroof.
