NOTICE
Park Assist uses parked vehicles, the kerbs and other objects as guidance. Make sure that the tyres
and wheel rims are not damaged when parking the vehicle. If necessary, stop the parking procedure
in good time to prevent damage to the vehicle.
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 (TCS) must be switched on ⇒ 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 road): not above
40 km/h (25 mph).
Speed when driving past the parking space (for parking spaces perpendicular to the road): not above
20 km/h (12 mph).
Maximum speed: 7 km/h (4 mph). An automatic braking intervention can take place when driving
into a parking space.
No trailer is connected electrically with the factory-fitted towing bracket ⇒ Notes on towing a
trailer .
The parking manoeuvre can be continued after the automatic brake intervention.
The automatic braking intervention takes place a maximum of once per parking manoeuvre. The
parking manoeuvre will be cancelled if a speed of approximately 7 km/h (4 mph) is exceeded again.
WARNING
Do not let the automatic braking intervention triggered by Park Assist tempt you to take any risks
while driving. The system is not a substitute for the full concentration of the driver.
Park Assist has system-related limitations. In some situations, automatic braking intervention may
function only in a limited way or not at all.
You should always be prepared to brake the vehicle yourself.
The automatic braking intervention is ended after approximately 1.5 seconds. Depress the brake
pedal of the vehicle yourself following the automatic braking intervention.
Looking for a parking space

First read and observe the introductoryinformation and safety warnings⇒Introduction
Park Assist has three parking modes ⇒ Fig. 130 (illustration).
Reverse parallel parking.Reverse perpendicular parking.Forward perpendicular parking.
Drive slowly past a row of parked vehicles, paying attention to the traffic.
Press the button. Park Assist automatically searches for a suitable parking space on the front
passenger side.
Stop when Park Assist displays a recommended parking mode on the instrument cluster display.
Drive into the parking space when a corresponding prompt ⇒ Fig. 131⑤ is shown on the
instrument cluster display ⇒ Driving into a parking space .
If you want Park Assist to search for a parking space on the opposite side of the road, operate the
turn signal for the corresponding side.
Changing parking mode
If Park Assist has found other alternative parking modes, these will be displayed in a miniature view.
They can be selected in turn by repeatedly pressing the button. Park Assist will switch itself off
after selection of all found parking modes. The originally recommended parking mode is offered
when the button is pressed again.
If you wish to park in a perpendicular parking space in forward direction, select Forward
perpendicular parking ⇒ Fig. 130 . Otherwise the vehicle will reverse into the perpendicular
parking space.
Park Assist can be activated retrospectively. If the vehicle has previously driven past a suitable
parking space, it will be displayed.

Accelerate carefully.
Brake when an acoustic signal sounds, the display lights up or until the prompt to drive forward
appears on the instrument cluster display.
Depress the brake pedal until Park Assist has finished steering or until the display in the
instrument cluster display will go out.
Repeat reversing and driving forwards until a corresponding message is displayed on the instrument
cluster. A signal tone may also sound.
Take over steering with the steering angle set by Park Assist.
Drive the vehicle out of the parking space when permitted by the traffic situation.
Troubleshooting
First read and observe the introductoryinformation and safety warnings⇒Introduction
The system is not responding as expected
The 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 system requirements must be met ⇒ Prerequisites .
The sensors are covered by water.
The vehicle is damaged in the area of the sensors, e.g. caused by parking collisions.
The detection ranges of the sensors are blocked by add-on parts, e.g. bicycle carriers.
Changes have been made to the paintwork in the area of the sensors or structural modifications
have been made, e.g. on the vehicle front end or the running gear.
The ultrasound signal is subject to interference from external noise sources, e.g. rough tarmac
surface or cobblestones.
No sensor visibility, error message, system switches itself off
Park Assist is switched off if a sensor fails.
Clean the sensors or remove stickers or accessories from the sensors and cameras ⇒ Caring for and
cleaning the vehicle exterior .
Check whether any damage is visible.
Possible solution
Switch off the system temporarily.
Check whether any of the causes described apply.
You can switch the system back on again once you have rectified the cause of the problem.
If the system still fails to respond as expected, have the system checked by a qualified workshop.
Automatic cancellation of driving in/out of a parking space
Park Assist cancels parking or driving out of a parking space in the following situations:
The button is pressed.
The driver intervenes using the steering wheel.
The driver door is opened.
The parking operation is not completed within around six minutes.
There is a system fault.
TCS is switched off or is taking corrective action.
Automatic braking intervention to minimise damage
In some countries, Park Assist can assist the driver with an automatic braking intervention in certain
situations ⇒ .
Depending on the vehicle equipment and certain conditions, e.g. weather, load or inclination of the
vehicle, Park Assist can automatically brake the vehicle before an obstacle. Following this
intervention, the driver must depress the brake pedal.
The parking manoeuvre is ended if an automatic braking intervention occurs.
Rear Traffic Alert
Fig. 133 Illustration of Rear Traffic Alert: monitored area around the vehicle leaving the parking
space.
Fig. 134 Display in the Infotainment system: Rear Traffic Alert.
Rear Traffic Alert is part of the Blind Spot Monitor ⇒ Driving with the Blind Spot Monitor .
Switching on and off
By means of the Assist systems menu in the instrument cluster ⇒ Vehicle settings menu .
OR: with some equipment levels, by means of the button for the driver assist systems ⇒ Button for
driver assist systems .
OR: with some equipment levels, in the Driver assistance menu in the Infotainment system
⇒ Infotainment system controls and displays .
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. 134 :
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.
In vehicles with Park Distance Control, an acoustic signal will sound with the continuous tone of Park
Distance Control. 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 system fault in the scanned area, the indicator lamp will light up yellow on the
instrument cluster display.
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.
Automatic braking intervention is activated 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.
Automatic braking intervention can be interrupted by pressing the accelerator or brake pedal
sharply and taking control of the vehicle.
Automatic deactivation
Rear Traffic Alert is deactivated automatically and cannot be switched on if the factory-fitted towing
bracket is electrically connected to a trailer or similar ⇒ Notes on towing a trailer . Once a trailer is
electrically connected to the vehicle and the driver pulls away, a text message appears in the
instrument cluster display to inform the driver that Rear Traffic Alert has been deactivated. Rear
Traffic Alert will be automatically activated again when the trailer has been unhitched from the
vehicle. This applies if the functions were previously activated. Rear Traffic Alert must be switched
off manually for trailer towing if a non-factory-fitted towing bracket is used.
WARNING
The intelligent Rear Traffic Alert technology cannot overcome the laws of physics, and functions only
within the limits of the system. Do not let the assistance function of Rear Traffic Alert tempt you to
take any safety risks while driving. The system is not a substitute for the full concentration of the
driver.
