Park Assist (hereinafter referred to as 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.
1)
The area behind the vehicle can be displayed for a few seconds more after disengaging the reverse gear.
144Driving
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 140 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.WARNING■ The general information relating to the use of assistance systems must
be observed » page 135, 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. Therefore, 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. 164 on page 146 or by a driver steering intervention.Functioning

Automatic brake assist when speeding
If a velocity of 7 km / h is exceeded during the parking manoeuvre for the first
time, the speed will be automatically reduced by the system to less than 7 km /
h. This prevents the parking manoeuvre from aborting.
Automatic emergency braking
If the system detects a risk of collision during parking, automatic emergency
braking takes place to prevent a collision.
The parking is terminated by the emergency braking.

The Cruise Control System (CCS) maintains a set speed without you having to
actuate the accelerator pedal.
The state where the CCS maintains the speed is referred to hereinafter as the
control .
WARNING■
The general information relating to the use of assistance systems must
be observed » page 135, in section Introduction .■
After pressing the clutch pedal, no interrupted control occurs! For exam-
ple, if a different gear is engaged and the clutch pedal is released, control is
continued.

If no speed is set, the current speed is used.
At the start of the control process, the CCS regulates the vehicle to the current
speed, and this speed is shown on the instrument cluster display. The warning
light illuminates in the instrument cluster.
Automatic control interruption
Automatic control interruption occurs if any of the following conditions are met. ▶ The brake pedal is operated.
▶ When one of the brake assist systems (e.g. ESC) intervenes.
▶ Through an airbag deployment.
WARNING■ Always deactivate the cruise control system after use to prevent uninten-
tional switching on of the system.■
Control may only be resumed if the set speed is not too high for the cur-
rent traffic conditions.

The automatic distance control (hereinafter referred to as ACC) maintains the
set speed or the distance to the vehicle ahead without the accelerator or
brake pedal being pressed.
The front of the vehicle and the distance to the vehicle ahead is monitored by
a radar sensor » page 135.
The state in which the ACC maintains the speed or the proximity is described
as control from here on.
WARNING■
The general information relating to the use of assistance systems must
be observed » page 135, in section Introduction .■
The driver must always be ready to take over steering of the vehicle him-
self (accelerate or brake).
■
The ACC does not react when approaching a stationary obstacle, such as
traffic jams, vehicle breakdowns or vehicles waiting at a traffic light.
■
The ACC does not respond to crossing or oncoming objects.
■
If the ACC does not decelerate fast enough, immediately apply the vehi-
cle's foot brake.
WARNINGFor safety reasons, do not use the ACC under the following conditions.■When driving in turning lanes, motorway exits or construction sites, to
avoid an unwanted acceleration to the stored speed.■
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
■
When road conditions are poor (e.g. ice, slippery road, gravel, dirt road).
■
When driving around “sharp” bends.
■
When riding on a steep gradient / high slope.
■
When driving through places where metal objects (such as metal build-
ings, railroad tracks, etc.) can be found.
■
When driving through very divided and enclosed spaces (such as large-ca-
pacity garages, car ferries, tunnels and the like.).
Note
■ The ACC is designed primarily for use on motorways.■The ACC reduces the speed by automatically releasing the accelerator or by
means of a braking procedure as appropriate. If the brakes are used for an au-
tomatic speed reduction at any moments, then the brake light illuminates.■
In case of failure of more than one brake light on the vehicle or on the con-
nected trailer, the ACC becomes unavailable.
■
The control automatically cancels the engagement of the brake supportive
assistance systems (e.g. ESC) or when the maximum permitted engine speed is
exceeded.

on page 150 first.
The ACC allows a speed of 30 - 160 km/h to be set or a distance to the preced- ing vehicle to be very short of very long to be set.
The ACC adjusts the set speed with respect to the detected vehicle ahead,
thus maintaining the selected proximity.
The ACC can detect a vehicle that is up to approx. 120 m ahead using the radar sensor.

instrument cluster, the warning light
lights up and the display shows the
following message.Apply the brake!
Note
Some ACC notifications in the display of the instrument cluster may be hidden
by notifications for other functions. An ACC notification automatically appears
for a brief moment when there is a change in status of the ACC.
Automatic stop-start
Read and observe
on page 150 first.
Vehicles with an automatic transmission can decelerate to a standstill and
start moving again using the ACC.
Decelerate to a standstill
If a vehicle ahead decelerates to a standstill, the ACC will also decelerate your
vehicle to a standstill.
Starting to drive again after a holding period
As soon as the vehicle ahead starts moving again after a holding period, your
vehicle will also move and the speed will continue to be regulated. Control is
automatically disconnected in case of longer holding periods.
Depress the brake pedal.
