Audi Q7 - Audi Pre Sense Rear

22
Audipresenserear now initiates the following actions, which can
be subdivided into two phases.
Phase1
1. Initially, the indicators flash rapidly for about 3seconds
1)
. This
flashing cycle is known as the RECAS warning, RECAS being the
abbreviation for Rear End Collision Avoidance System. Due to
the high frequency at which the indicators are activated,
humans see these signals as flashes of light. The flashing of
the indicators alerts the drivers in following vehicles to a
critical situation ahead and animates them to take appropriate
action, e.g. initiate braking. The time of activation of the RECAS
warning depends on the severity of the critical situation and
the relative speed
3)
of the following vehicles. The onboard
power supply control unit J519 activates the RECAS warning.
If the driver in the following vehicle reacts during this phase, e.g.
brakes or takes evasive action, and Audi lane assist control units
J769 and J770 no longer detect a critical situation, then no further
action, e.g. closing of the side windows, is taken.
1)
Not available in all countries.
2)
Optional equipment.
3)
The relative speed is the dierence in speed between one's own vehicle and the following vehicle.

panoramic glass sunroof
2)

with pneumatic front sport seats
2)
or with individual contour

cates that Audipresense is active.
