Function
Rear Traffic Alert monitors the traffic crossing behind the vehicle when reversing out of a parking
space or manoeuvring. Rear Traffic Alert functions using radar sensors in the rear bumper.

Do not drive on!
Possible critical situation.
Detection of a critical situation can also take place acoustically:
• A warning signal will sound and a text message will be displayed in the instrument cluster for
vehicles without Park Distance Control.
• A warning signal will sound with the continuous Park Distance Control tone if Park Distance
Control is installed in the vehicle. If the Park Distance Control is deactivated, no warning can be
given to the driver and the Rear Traffic Alert system will also be switched off temporarily.
If there is a fault in the system's scanned area, the
yellow
indicator lamp lights up .
Automatic braking intervention to minimise damage
If Rear Traffic Alert detects an approaching road user and the driver has not pressed the brake, the
system can brake automatically.
The Rear Traffic Alert helps the driver to prevent damage by initiating an automatic braking
intervention. Automatic braking intervention takes place when reversing at speeds of between
1-12 km/h (1-7 mph). The vehicle is held stationary for up to two seconds after vehicle standstill has
been detected.
After automatic braking intervention is activated to prevent damage to the vehicle, the system
requires approximately ten seconds before it can activate another automatic braking intervention.
The automatic braking intervention can be interrupted by pressing the accelerator or brake pedal
sharply and taking control of the vehicle.
Troubleshooting

. The sensor visibility
may be impaired by dirt and snow or also residue from cleaning agents or coatings.
• The prerequisites for system operation must be met
⇒
System limits
.
• The radar sensors are covered by water.
• The vehicle is damaged in the area of the radar sensors, e.g. caused by parking collisions.
• The detection ranges of the radar sensors are blocked by add-on parts, e.g. bicycle carriers.
• Changes have been made to the paintwork in the area of the radar sensors or structural
modifications have been made, e.g. on the vehicle front end or the running gear.
• Tinting foils have been retrofitted on the side windows.
The intelligent technology of the lane change system including Rear Traffic Alert cannot
overcome the laws of physics, and functions only within the limits of the system. Do not
let the auxiliary function of the Rear Traffic Alert tempt you to take any risks while driving
– this can cause accidents. The system is not a substitute for the full concentration of the
driver.
• Never use the system with impaired vision or in unpredictable traffic situations, e.g. on
extremely busy roads or across several lanes.
• Always pay attention to the area around the vehicle – cyclists and pedestrians are
often not clearly detected.
• The Rear Traffic Alert will not always independently bring the vehicle to a complete
stop.
