Audipresensecity is a "camera based" system. To use Audi
pre sensecity, therefore, Driver Assistance Systems Front
Camera R242 must be installed. The front camera continu-
ously monitors the trac ahead of the vehicle. Among
other things, it makes allowance for the distance to and
speed of other objects relative to one's own vehicle.
Response to vehicles Response to pedestrians
The following preconditions must be met in order to acti-
vate the system:
• presensecity can respond to vehicles which are travel-
ling in the same direction and which have stopped or are
stationary.
• presensecity does not respond to crossing or oncoming
trac.
• presensecity is active upwards of a speed of about
6.2 mph (10 km/h).
Response to vehicles
• presensecity can warn against vehicles up to a speed of
155.3 mph (250 km/h).
• presensecity can initiate braking up to a speed of
52.8 mph (85 km/h).
Collision warning phase
If the vehicle approaches another vehicle which is traveling in
the same direction (up to a speed of 155.3 mph [250 km/h])
or has stopped, resulting in a critical driving situation, the
instrument cluster gives the driver audible and visual early
warnings when set limits are exceeded.

• Automatic braking up to emergency braking intensity.
• Activation of the hazard warning ashers (emergency
braking warning)

.
Depending on the severity of the critical driving situations,
Audi pre sense city can warn the driver rst and then, if
necessary, initiate braking. The system can, under certain
conditions, detect the following scenarios:
• Vehicle ahead.
• Pedestrians standing in the same lane or approaching
the same lane as the vehicle.
