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. 113. A display in the MMI and 
various warnings provide assistance when exiting 
a parking space. 
Requirements for using the rear cross-traffic 
assist: 
— 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 system is active. In vehicles with pe- 
ripheral cameras, the display appears in the 
Rear and Rear corner camera views. Arrows 
show the direction from which the cross traffic 
is approaching. 
— Audible warnings: a continuous tone 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 ap- 
proaching object. 
The audible warning signal and the automatic 
brake activation occur only when driving in re- 
verse.

Assisted parking 
General information 
Applies to: vehicles with park assist 
If your vehicle is equipped with park assist, this 
system helps you find suitable parking spaces. 
Parking spaces are measured using ultrasonic 
sensors on the sides of the vehicle. 
If a parking space is found, the system helps you 
to park while the driver monitors the vehicle's 
surroundings with the parking aids, cameras”, 
and direct eye contact. The vehicle moves the 
steering wheel autonomously.

in the wheel hub clean and free of grease.

Loose wheel warning 
Applies to: vehicles with loose wheel warning 
       
Within the limits of the system, the loose wheel 
warning in the instrument cluster warns you if 
one or more wheels are loose. 
Using the ABS sensors, the loose wheel warning 
system compares the vibration characteristics of 
the individual tires. If one or more wheels are 
loose, it will be indicated in the instrument clus- 
ter display with the & indicator light and a mes- 
sage. If only one wheel is affected, the location 
of that wheel will be indicated.
