Park Assist (following referred to system) helps drivers park in suitable parallel
and perpendicular parking places or also to manoeuvre out of parallel parking
spaces.
The system takes over the steering movements when parking or leaving a
parking space. The driver operates the pedals and the shift lever or gear selec-
tor.
The state in which the steering wheel is operated by the system, is referred to
as parking operation.
The Park Assist is an extension of the parking aid » page 147 and operates on
the basis of data collected by the ultrasonic sensors.
For this reason, the chapter on the parking aid is to be read carefully and the safety notes are to be observed.
155Assist systems
WARNING■The general information relating to the use of assistance systems must
be observed » page 142, in section Introduction .■
During the parking process, the system automatically performs rapid
steering movements. While it is doing so, do not place your hands between
the steering wheel – risk of injury!
■
During a parking manoeuvre on loose or slippery surfaces (gravel, snow,
ice, etc.) you may stray from the calculated road. It is therefore recommen-
ded that you do not use the system in such situations.
CAUTION
The correct evaluation of the parking space and the parking procedure de-
pends on the circumference of the wheels on the vehicle.■
The system only works correctly if the vehicle is fitted with the wheel size
approved by the manufacturer.
■
Abstain from using the system when the vehicle is fitted with snow chains or
a temporary spare wheel.
■
If wheels other than those approved by the manufacturer are mounted, the
resulting position of the vehicle in the parking space can differ slightly. This
can be avoided by readjusting the system at a specialist garage.
CAUTION
If other vehicles are parked behind the kerb or on it, the system can also guide
your vehicle beyond the kerb or onto it. Ensure that the wheels or the wheel
rims of your vehicle are not damaged and if necessary intervene in time.
Note
■ We recommend performing the parking at a safe speed to about 5 km / h.■The driver can stop the parking process at any time by pressing the symbol
key » Fig. 191
on page 156 or by a driver steering intervention.FunctioningFig. 191
System button
Read and observe and on page 156 first.
The system support is provided in the following manner.
▶ While the parking space search is going on, a measurement and evaluation of
the parking space size is completed.
▶ The display of the instrument cluster (hereinafter only display) shows suita-
ble parking spaces and a parking mode is recommended.
▶ The display shows instructions and information before the start and during
the parking.
▶ The road way is calculated that the vehicle uses during the parking.
▶ The front wheels are automatically rotated during the parking.
Conditions for the system function
The system can look for a parking space only if the following basic conditions
are met.
The system is activated.
The vehicle speed is less than 40 km / h (parallel parking).
The vehicle speed is less than 20 km / h (transverse parking).
The distance to a number of parked vehicles is approximately 0.5 - 1.5 m.
The TCS is activated » page 143, Braking and stabilisation systems .
The system can only carry out the parking if the following basic conditions are
met.
The vehicle is travelling less than about 7 km/h.
The parking procedure takes less than 6 minutes.
There is no driver intervention in the automatic steering operation.
Activation/deactivation
The system can be enabled or disabled by pressing the symbol key » Fig. 191

, let go of the steering wheel. The steering will be taken over
by the system.

Observe the direct vicinity of the vehicle and reverse carefully.
If necessary, the parking procedure can be continued with further steps.
›
If the forward arrow flashes in the display - , engage 1st gear or move the
gear selector to position D / S.

›
Carefully move backwards.
You can repeat these steps several times in succession.
As soon as the parking procedure is completed, an audible signal sounds and
the following message appears in the display:
Park Assist stopped. Take over steer-ing!

158Driving
With automatic braking the symbol appears » Fig. 208 in the display.
Advance warning
If the system detects a risk of collision, the symbol
» Fig. 208 appears in the
display and you will hear an acoustic signal.
At the same time, the braking system is prepared for possible emergency brak- ing.
The pre-warning display can occur in the following situations.
▶ If there is a risk of collision with a moving obstacle in a driving speed range of
about 30 km/h to about 210 km/h.
▶ There is a risk of a collision with a stationary moving obstacle in a vehicle
speed range of approximately 30 km/h to about 85 km/h.
With a warning the brake pedal must be pressed or the moving obstacle is to
be avoided!
Acute alert
If the driver does not react to the advance warning, the system briefly applies
the brake automatically via an active brake intervention to draw attention to
the potential danger of a collision again.
Automatic Braking
If the driver fails to respond to the acute warning, the system starts to apply
the brakes automatically with increasing stopping power in several stages.
Brake assist
If the driver brakes inadequate with an impending collision, the system auto-
matically increases braking force.
The braking assistance only occurs as long as the brake pedal is being firmly
pressed down.
Note
■ If an automatic brake intervention is triggered by the system, the pressure in
the brake system increases and the brake pedal cannot be operated with the
normal pedal stroke.■
The automatic braking interventions can be cancelled by pressing the accel-
erator pedal or by steering intervention.

When the vehicle approaches a detected line between lanes, the system
makes a light movement of the steering wheel in the opposite direction to the
boundary line. This corrective steering intervention can be manually overrid-
den at any time.WARNING■ Please take note of the general points relating to the use of assistance
systems » page 142, in section Introduction .■
Lane Assist can help you keep the vehicle within the lane. However, it
does not steer the vehicle for you. The driver retains full responsibility for
steering at all times.
■
Some objects on the road may be incorrectly detected as lines. As a re-
sult, an incorrect steering intervention may take place.
WARNINGThe detection capability of the camera may be limited by various external
influences. In such cases, the assistant may not detect the line between
two lanes at all or not properly. The detection capability of the camera may
be restricted in the following situations, for example.■
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When driving around “sharp” bends.
■
The camera is blinded by the sun.
■
The camera is blinded by the oncoming traffic.
■
The viewing range of the camera is impeded by a vehicle travelling ahead.
■
The camera viewing range is obstructed by an obstacle.
CAUTION
Do not attach any stickers or similar objects to the windscreen to avoid impair-
ing the functions of the systems.
Note
■ The system is designed for driving on motorways and roads with adequate
longitudinal markings.■
The system can detect both continuous and broken lines.

The system can intervene when the following basic conditions are present.The system is activated.
The vehicle is travelling at more than about 65 km/h 1)
.
The boundary lines are clearly visible (appropriate longitudinal markings).
The boundary line of at least one side of the lane is detected.
The driver's hands are on the steering wheel.
The lane is more than 2.5 m in width.
If the turn signal is switched on prior to driving over the boundary line (e.g.
when making a turn), no steering intervention takes place when the vehicle
approaches the boundary line. The system regards the situation as an inten-
ded lane change.
Warning lights in the instrument clusterWarning lightMeaningThe system is active, but not ready to intervene.The system is active and ready to intervene or is currently
intervening.
Adaptive lane assist
Adaptive lane assist helps to keep the vehicle in the position between the
boundary lines selected by the driver, by means of steering intervention.
If the system detects only one boundary line, it will help to maintain the selec-
ted proximity from said boundary line.
If the proximity to the detected boundary line is changed, the system quickly
adapts and maintains the newly-selected position.
WARNINGThe system function may be restricted if, for example there is danger due
to ruts on a downhill road or in a crosswind.Activation / deactivation
