Audi A6 Typ 4G: Audi pre sense
Preventative passenger protection
Applies to: vehicles with Audi pre sense
Pre sense can initiate steps to protect vehicle occupants
in certain dangerous situations. The
functions described are available depending on
vehicle equipment:
Pre sense basic
The following functions can be triggered in certain
driving situations:
- Tensioning of the safety belts (for example,
during heavy braking): the front safety belts
have reversible belt tensioners. If a collision
does not occur, the safety belts loosen slightly
and are ready to trigger again.
- Closing the windows and the sunroof (for example,
when over- or understeering): the windows
and the sunroof close until there is only
a small gap open.
The function of the pre sense basic is activated at
a speed of 20 mph (30 km/h) or higher.
Drive select: the deployment time is adapted in
Dynamic mode.
Pre sense front (vehicles with adaptive cruise
control)
Pre sense front contains the functions of pre
sense basic. In addition, the likelihood of a rear-end
collision with the vehicle ahead is also calculated,
within the limits of the system. If the risk
of a collision is detected, the following functions
can trigger:
- Braking guard
- Tensioning of the safety belts
- Closing the windows and the sunroof
Pre sense rear (vehicles with side assist)
Pre sense rear contains the functions of pre sense
basic. In addition, the likelihood of a rear-end
collision from the vehicle behind is also calculated,
within the limits of the system. If the risk of a
collision is detected, the following functions can
trigger:
- Tensioning of the safety belts
- Closing the windows and the sunroof
Pre sense plus
Pre sense plus contains the functions of pre
sense front and pre sense rear.
Error message
Audi pre sense: Unavailable
Preventative passenger protection is not available.
Drive to your authorized Audi dealer or authorized
Audi Service Facility immediately to have
the malfunction corrected.
WARNING
Pre sense cannot overcome natural physical
laws. It is a system designed to assist and it
cannot prevent a collision. Do not let the increased
safety provided tempt you into taking
risks. This could increase your risk of a collision.
- The system can deploy incorrectly.
- Please note that the sensors do not always
detect all objects. This increases the risk of
a collision.
- Pre sense does not react to people or animals
or objects that are crossing the vehicle's
path or are difficult to detect.
- Reflective objects such as guard rails or the
entrance to a tunnel, heavy rain and ice can
affect the function of the radar sensors and
the system's ability to detect a collision risk.
Note
The sensors can be displaced by impacts or
damage to the bumper, wheel housing and
underbody. Pre sense can be impaired by this.
Have an authorized Audi dealer or authorized
Audi Service Facility check their function.
Tips
- Certain pre sense front functions switch off
when sport mode is switched off or when
driving in reverse.
- The pre sense functions may not be available
if there is a malfunction in the ESC
system or the airbag control module.
- The pre sense front/plus functions are not
available if there is a malfunction in the
adaptive cruise control system.
- The pre sense rear/plus functions are not
available if there is a malfunction in the side
assist system.
