Audi A4: Rear cross-traffic assist
Description
Applies to: vehicles with rear cross-traffic assist
Fig. 130 Sensor
Fig. 131 Center display: rear cross-traffic assist display
General information
The rear cross-traffic assist monitors the area behind
and next to the vehicle using radar sensors
at the rear corners of the vehicle. The system can
detect moving objects that are approaching, such
as vehicles > fig. 130. A display in the MMI (1)
and various warnings provide assistance when exiting
a parking space.
Requirements for using the rear cross-traffic
assist:
- The parking aid is switched on or
reverse gear is selected.
- The speed when driving in reverse must not be
higher than approximately 9 mph (15 km/h).
Displays, warnings, and braking
- Display: the display (1) appears only when the
parking aid is active. In vehicles with peripheral
cameras, the display only appears in the Rear
and Rear corner camera views. Arrows show the
direction from which the cross traffic is approaching.
- Audible warnings: an audio signal may sound
as an additional warning when driving in reverse.
- Automatic brake activation: if you do not react
to a warning, a brief braking by the system can
warn you of a potential collision with an approaching
object.
The audible warning signal and the automatic
brake activation occur only when driving in reverse.
Switching the rear cross-traffic assist on and
off
- Applies to MMI: Select on the home screen: VEHICLE
> Parking aid > Rear cross-traffic assist.
Or
- Select > Rear
cross-traffic assist in the center
display when the parking system is active.
Messages
If or
is displayed when there is a
malfunction,
the rear cross traffic assist functions
may be unavailable or may be limited.
A message that indicates the cause and possible
solution may appear with some displays. The
weather conditions may be too poor or a sensor
may be covered. Clean the area of the sensors at
the rear corners of the vehicle
fig. 103 and try to turn the system on again later.
If the malfunction remains, drive to an authorized
Audi dealer or authorized Audi Service Facility
immediately to have the malfunction corrected.
WARNING
- Observe the safety precautions and note the
limits of the assist systems, sensors, and
cameras.
- The rear cross-traffic assist will not provide
alerts about people and cannot warn you
about every type of approaching objects,
such as cyclists. Always monitor the traffic
as well as the vehicle's surroundings with direct
eye contact.
- The system may not react at all or it may not
react on time when objects are approaching
very quickly.
- The rear cross-traffic assist will not provide
alerts if your vehicle is parallel or diagonally
parked or if your vehicle is pulled too far into
the parking space so that it is hidden by
adjacent vehicles.
Tips
- Once an automatic brake activation occurs,
the system cannot initiate another activation
for several seconds.
- System functions may not be available if the
ESC is limited or switched off, or if there is a
malfunction.
- If there is an audio warning signal from the
rear cross-traffic assist, then the parking aid
may not be able to provide audio warnings
about detected obstacles under certain circumstances.
- The system complies with United States FCC
regulations and ISED regulations.
- The coverage areas of the sensors > fig. 130
are diagrams and do not represent a true-to-
scale image of the sensor ranges.
