If the sensors detect an obstacle, audible and vis-
ual signals will warn you.
Visual warnings
The visual warnings in the upper display help you
to detect the critical vehicle area and to estimate
the distance to an obstacle.
Red segments (@) show detected obstacles that
are in your vehicle's path. The red lines 2) mark
the expected direction of travel based on the
steering angle. A white segment (8) indicates a
detected obstacle that is outside of the vehicle's
path. The closer your vehicle comes to the obsta-
cle, the closer the segments will move to the ve-
hicle. The collision area has been reached when
the next to last segment is displayed. Obstacles
in the collision area, including those outside of
the vehicle's path, are shown in red. Do not con-
tinue driving farther.
Audio signals
The closer your vehicle gets to a detected obsta-
cle, the shorter the time between the audible sig-
nals. A continuous tone sounds when an obstacle
is less than approximately 1 foot (0.30 m) away
from the front or rear of the vehicle. A continu-
ous tone sounds when an obstacle is less than

General information
The rear cross-traffic assist monitors the area be-
hind 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. 126. A display in the MMI and
various warnings provide assistance when exiting
a parking space.
Requirements for using the rear cross-traffic
assist:
— The parking system is switched on > page 166.
— Reverse gear must be engaged and the speed
while driving in reverse must not be higher than
6 mph (10 km/h).
Displays, warnings, and braking
— Display: the display @ 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 ap-
proaching.
— Audible warnings: an audio signal may sound
as an additional warning when driving in re-
verse.
— 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 ap-
proaching object.
The audible warning signal and the automatic
brake activation occur only when driving in re-
verse.
