Applies to: vehicles with Audi pre sense
The pre sense functions can take action to protect the vehicle occupants and other road users in certain hazardous conditions within the system limits.
- Pre sense basic uses a network of different on-board systems, such as the ESC, to initiate measures to protect the vehicle occupants if it detects an unstable driving condition.
- Pre sense front uses the data from the radar sensors for the adaptive cruise control* and from the camera to calculate the likelihood of a collision with the vehicle in front. An impending collision with other vehicles can be detected within the limits of the system at various speeds both in town and on country roads. In this case, the system warns the driver visually, acoustically and, if necessary, with a short, sharp brake application. If necessary, it can initiate a partial or full brake application in order to reduce the impact speed or, in certain circumstances, to avoid a collision. In conjunction with pre sense basic/rear, the reversible tensioners on the front seat belts are also applied if necessary. Pre sense front is active even when the adaptive cruise control* is switched off.
- Pre sense rear includes the functions of pre sense basic. It uses the data from the radar sensors for the side assist* to calculate the likelihood of a collision with the vehicle behind, within certain system limits. Pre sense rear is active even when the side assist* is switched off.
- Pre sense city uses the data from the camera to detect an impending collision with other vehicles or pedestrians, within certain system limits. In this case, the system warns the driver visually, acoustically and, if necessary, with a short, sharp brake application. If necessary, it can initiate a full brake application in order to reduce the impact speed or, in certain circumstances, to avoid a collision. In conjunction with pre sense basic/rear, the reversible tensioners on the front seat belts are also applied if necessary.
Note
- Certain pre sense functions are deactivated 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.
- Please note that, if the front passenger s airbag has been deactivated, the reversible belt tensioner on the passenger s side will be deactivated as well.
- Switch off pre sense on private roads and while the vehicle is being loaded onto a car transporter, train or ferry, etc. This prevents the pre sense system from taking action in an inappropriate situation.
