Pre sense can take action to protect the occupants in certain hazardous conditions. The equipment installed on your vehicle determines which of the described functions are available:
Pre sense basic*
The following functions can be activated automatically in certain situations:
- Seat belt tensioning (e.g. during hard braking): The seat belts on the front seats have reversible tensioners. Provided an accident does not occur, the belts are loosened again slightly and kept ready for activation.
- Windows and sun roof* automatic close function (e.g. during understeer or oversteer): A small gap is left when closing the windows and sun roof*.
- Activation of hazard warning lights 1)
Pre sense basic functions are activated at speeds above 30 km/h.
Drive select: the activation threshold is different in dynamic mode.
Pre sense front (vehicles with adaptive cruise control*)
Pre sense front includes the functions of pre sense basic. In addition, the probability of a collision with the vehicle in front is calculated (within the limits imposed by the system). The following functions can be activated if the system detects a collision risk:
- Braking guard ►Link
- Seat belt tensioning
- Automatic closing of windows and sun roof*
- Activation of hazard warning lights 1)
Pre sense rear (vehicles with side assist*)
Pre sense rear includes the functions of pre sense basic. In addition, the probability of a collision with the vehicle behind is calculated (within the limits imposed by the system). The following functions can be activated if the system detects a collision risk:
- Seat belt tensioning
- Automatic closing of windows and sun roof*
- Activation of hazard warning lights 1)
Pre sense plus*
Pre sense plus includes the functions of pre sense front and pre sense rear.
Fault warning
Audi pre sense not available
The preventive occupant protection system is not available. Drive to a qualified workshop without delay and have the fault rectified.
WARNING!
The protection provided by pre sense is still subject to the prevailing physical limits. It is a driver assist function and cannot prevent a collision on its own. Do not let the extra safety provided tempt you into taking any risks when driving – this can cause accidents.
- False activation of the systems is possible.
- Please note that the sensors are not always able to detect all objects which may represent a potential hazard - risk of accident!
- Pre sense does not react to people, animals, crossing traffic or objects that cannot be clearly recognised ►Link.
- Reflecting objects, such as crash barriers, the entrance to a tunnel, heavy rain or ice can impair the function of the radar sensors and the ability of the system to detect a collision risk.
Caution!
Impacts or damage to the bumper, wheel arches or underbody can cause misalignment of the sensors. This can impair the function of the pre sense system. Have the systems checked by a qualified workshop.
Note
- Certain pre sense functions are deactivated when the sport mode is switched on and when reversing.
- The functions of the pre sense system may also be unavailable if a fault develops in the ESC system or airbag control unit.
- The functions of pre sense front/plus will be unavailable if a fault develops in the adaptive cruise control* ►Link.
- The functions of pre sense rear/plus will be unavailable if a fault develops in the side assist* ►Link.
- If the front passenger's airbag has been deactivated, the reversible belt tensioner on the passenger's side will be deactivated as well.
