Parking
● Parking parallel to the road: Drive next to the gap at a speed of no more
than 40 km/h (25 mph) and at a distance of between 0.5 m and 2 m.
● Parking perpendicular to the road: Drive next to the gap at a speed of no
more than 20 km/h (12 mph) and at a distance of between 0.5 m and 2 m.
● The best parking results will be achieved if you position the vehicle as
parallel as possible to the line of parked cars or the kerb.
● When a suitable parking place is displayed on the instrument panel,
stop and select reverse gear.
● Follow the instructions given on the instrument panel display
● Then, release the steering wheel when the warning signal sounds ⇒
:
The system will move the steering wheel! Observe the surrounding area.
● Observe the surrounding area and accelerate carefully at a maximum of
up to 7 km/h (4 mph).
● The park assist system is only responsible for moving the steering wheel
during the manoeuvre. The driver applies the accelerator, the clutch, the
gears and the brake.
● Follow the instructions given by the park assist system until the ma-
noeuvre is completed.
● The park assist system steers the vehicle forwards and backwards until
it is in a straight position in the parking space.
● The manoeuvre is complete when the corresponding indication is given
on the instrument panel display.
Stopping the parking manoeuvre
The park assist system stops the manoeuvre in the event of one of the fol-
lowing:
● Press button
.
● When driving faster than 7 km/h (4 mph).
● The driver moves the steering wheel.
● The parking manoeuvre has not been completed after six minutes since
the park assist system was activated. ●
A sliding door is opened. To restart the manoeuvre, close the sliding
door and press the button
again.
● There is a system malfunction (system temporarily unavailable).
● The ASR system is switched off or the ASR or ESC is working.
WARNING
The steering wheel turns quickly by itself when parking using the park
assist system. Placing your hand between the steering wheel spokes
could lead to injuries.
Note
● The park assist system has its limitations. For example, it is not possible
to park on tight bends using the park assist system.
● Even if the park assist system recognises that there is not enough space
for parking the vehicle, the instrument panel display will still show this
place. In this case, the parking manoeuvre should not be requested.
● Changing gears between forward and reverse gears before indicated
(that is, before the signal from the parking sensor system) the parking re-
sults may not be ideal.
● For parallel parking (parallel to the road), a sound will tell the driver
when they must change from forward gears to reverse; the signal from the
parking sensor system does not indicate changes of direction.
● The park assist can also be activated afterwards, if you pass close to a
parallel parking space at a maximum of 40 km an hour (25 mph) or close to
a perpendicular parking space at about 20 km an hour (12 mph) and then
press the
button.
● The progress bar on the screen of the instrument panel shows a display
of the relative distance to be covered.
● When the Park Assist system is turning the steering wheel of the stop-
ped vehicle the symbol is also displayed. Press on the brake pedal so
that the steering can turn with the vehicle at a standstill and thus reduce
the number of manoeuvres.

207
Driving
● A suitable parking space length is at least 1.1 m greater than the length
of the vehicle.
● If the results of the park assist system are not as good after changing
the wheels, the system must memorise the perimeter of the new wheels.
This process is performed automatically while the vehicle is in motion. To
help this process, turn slowly (at less than 20 km/h (12 mph)), e.g. in an
empty car park.
Leaving a parking space using the Park Assist system
Driving off
● Switch on the engine.
● Press button
. When the function is enabled, the button
⇒ Fig. 146
will light up.
● Apply the turn signal for the side on which you want to leave the parking
space.
● Select reverse gear.
● Follow the instructions given by the park assist system.
● When the next indication appears, release the steering wheel ⇒
in
Parking using the park assist system on page 206: The system will move the
steering wheel! Observe the surrounding area.
● Observe the surrounding area and accelerate carefully at a maximum of
up to 7 km/h (4 mph).
● The park assist system is only responsible for moving the steering wheel
during the manoeuvre. The driver applies the accelerator, the clutch, the
gears and the brake.
● When it is possible to leave the parking space, the Park Assist system
will stop. Take control of the steering and when traffic conditions permit,
leave the parking space. Automatic stoppage of the manoeuvre
The park assist system stops the manoeuvre in the event of one of the fol-
lowing:
●
When driving faster than 7 km/h (4 mph).
● The driver moves the steering wheel.
● A sliding door is opened. To restart the manoeuvre, close the sliding
door and press the button
again.
● There is a system malfunction (system temporarily unavailable).
● The ASR system is switched off or the ASR or ESC is working.
WARNING
The steering wheel turns quickly automatically when leaving a parking
space using the park assist system. Placing your hand between the steer-
ing wheel spokes could lead to injuries.
Park Assist brake operation
The Park Assist system helps the driver by braking automatically. Automatic
braking does not relieve the driver of responsibility for controlling the accel-
erator, brake and clutch ⇒
.
Braking to avoid damage at excess speed
It is possible that the system operates the brakes to reduce excess speed.
The parking manoeuvre can then continue. The brakes will intervene during
each parking process.
Braking to minimise damage
When approaching an obstacle, the vehicle may brake automatically. In cer-
tain circumstances (for example, storm, detection of ultrasounds, vehicle
status, load, inclination), the Park Assist system may stop the vehicle com-
pletely before an object.

Rear Assist system*
Introduction
The camera fitted to the rear lid helps drivers during parking or reversing
manoeuvres. The camera image and certain orientation points generated by
the system are indicated on the factory-fitted radio or navigation system
screen.
Two types of location point (modes) can be selected:
● Mode 1: reverse parking perpendicular to the road (e.g. in a car park).
● Mode 2: reverse parking parallel to the curb.
The mode can be changed by pressing the button on the radio or navigation
system screen. Only the mode to which the points can be changed will be
displayed.
Additional information and warnings:
● Accessories, parts replacement, repairs and modifications ⇒ page 261
WARNING
Use of the camera to calculate the distance from obstacles (people, vehi-
cles, etc.) is inaccurate and may cause accidents and severe injuries.
● The camera lens expands and distorts the field of vision and displays
the objects on the screen in a different, vague manner.
● Some objects may not be displayed or may not be very clear (e.g. very
thin posts or fences), due to the resolution of the monitor or if the light is
dim.
● The camera has blind spots in which obstacles and people are not
registered.
● Keep the camera lens clean and clear of snow and ice. Do not cover it.
WARNING
The intelligent technology in the rear assist system cannot change the
limits imposed by the laws of physics and by the system itself. Careless
or uncontrolled use of the rear assist system may result in severe injuries
and accidents. The system is not a replacement for driver awareness.
● Adjust your speed and driving style to visibility, road, traffic and
weather conditions.
● Always keep a close eye on the area around the vehicle and always
look towards where you are parking. The display shows the path of the
rear end of the vehicle using the current steering angle. The front of the
vehicle turns more in comparison with the rear.
● Do not be distracted from the traffic when looking at the screen.
● Always observe the area around the vehicle, as the cameras do not al-
ways detect children, animals or objects.
● The system might not show all areas clearly.
● Only use the rear assist system when the rear lid is completely
closed.
CAUTION
● The camera only displays 2D images on the screen. Due to the lack of
depth, it might be difficult or impossible to recognise protruding objects or
cracks in the road.
● The cameras may not always be able to detect objects such as thin rails,
fences, posts and trees, etc. This could result in damage to your car.
