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.
Key to ⇒ Fig. 150:
Critical situation. 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 mphyf 7 K H Y H K L F O H L V K H O G V W D W L R Q D U \ I R U X S W R W Z R V H F R Q G V D I W H U Y H K L F O H V W D Q G V W L O O K D V
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
First read and observe the introductoryinformation and safety warnings⇒
Introduction
No sensor visibility, error message, system switches itself off
•Clean the radar sensors or remove stickers or accessories from the radar sensors ⇒ Caring for
and cleaning the vehicle exterior.
•Check whether any damage is visible.
The system is not responding as expected
•The radar sensors are dirty ⇒ Caring for and cleaning the vehicle exterior. 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.

•Never leave children or people requiring assistance alone in the vehicle. They could
switch off the electronic parking brake, or move the selector lever or gearshift lever,
and thus set the vehicle in motion.
•Always take all vehicle keys with you every time you leave the vehicle. The engine can
be started and electrical equipment such as the window controls can be operated. This
can cause serious injury.
•Never leave children or people requiring assistance alone in the vehicle. They could
become trapped in the vehicle in an emergency and may not be able to get themselves
to safety. For example, locked vehicles may be subjected to very high or very low
temperatures depending on the season. This can cause serious injuries and illness or
fatalities, especially among small children.
WARNING
•Always take care when driving in car parks with protruding kerbstones or bollards.
Objects that protrude from the ground can damage the bumper and other components
when parking the vehicle or driving out of a parking space. Stop before the wheels
touch the fixed boundaries or kerbs.
•Drive carefully through dips in the road, over driveways, ramps, kerbstones and other

Park Assist
Introduction
This chapter contains information on the followingsubjects:
⇒ Prerequisites
⇒ Looking for a parking space
⇒ Driving into a parking space
⇒ Driving out of a parking space
⇒ Troubleshooting
Park Assist shows parking spaces
which are suitable for parking and
assists the driver when driving into and
out of parking spaces.
Park Assist is an extension of Park Distance Control ⇒ Park Distance Control.
Park Assist automatically steers the vehicle. The driver must control the accelerator, gear changes
and brake!
Driving into a parking space using Park Assist takes place in the following steps:
•Look for a parking space.
•Drive into a parking space.
System limits
The sensors may not always be able to detect objects such as trailer drawbars, thin rails, fences,
posts, trees and open or opening boot lids. This can result in damage to your vehicle.
In some cases, dirt and ice on the sensors could be registered as an obstacle.
Prerequisites
First read and observe the introductoryinformation and safety warnings⇒
Introduction
The following prerequisites must be met for driving into and out of parking spaces:
•The traction control system (TCSyf P X V W E H V Z L W F K H G R Q ⇒ Brake support systems.
•Distance: maintain a distance of 0.5 – -2.0 metres when driving past the parking space.
•The parking space must have at least the dimensions required by Park Assist.
•Speed when driving past the parking space (for parking spaces parallel to the roadyf Q R W D E R Y H
40 km/h (25 mphyf.
•Speed when driving past the parking space (for parking spaces perpendicular to the roadyf Q R W
above 20 km/h (12 mphyf.
•Maximum speed: 7 km/h (4 mphyf. An automatic braking intervention can take place when
driving into a parking space.
The parking manoeuvre can be continued after the automatic brake intervention.
Fast steering wheel movements can cause serious injury.
•During the manoeuvring operation, do not reach for the steering wheel until prompted
to do so by the system.
•Exception: if a dangerous situation occurs, intervene and take over the steering.
