The following restrictions may apply if the  
weather or lighting conditions are unfavourable:  
Impaired detection of vehicles.  
Brief interruptions when vehicles have already  
been detected.  
Examples of unfavourable weather or lighting  
conditions:  
Wet roads.  
Snowfall.  
Slush.  
If the desired speed is too high for cornering, it  
will be reduced slightly in the bend. However, the  
system may not detect bends in advance, so  
moderate your speed when cornering.  
Fog.  
The system has a limited detection range. Situa‐  
tions can arise on tight bends where a vehicle  
driving in front will not be detected or will be de‐  
tected very late.  
Oncoming light.  
Pay attention when driving and respond to the  
prevailing traffic conditions. If necessary, inter‐  
vene actively, for example by braking, steering or  
taking evasive action.  
Engine power  
The desired speed is also maintained when driv‐  
ing downhill. The vehicle may drive slower than  
the desired speed on uphill gradients if there is  
not enough engine power.  
In ECO PRO drive mode, it is possible that the  
vehicle will intentionally drive faster or slower  
than the desired speed setting in some situa‐  
tions, for example on downward or upward gradi‐  
ents.  
When your vehicle is approaching a bend, the  
angle of the bend may cause the system to re‐  
spond temporarily to vehicles in the other lane. If  
the system responds by decelerating the vehicle,  
you may compensate for this by accelerating  
briefly. When the accelerator pedal is released  
again, the system will resume control of the vehi‐  
cle's speed.  
Malfunction  
Radar sensor  
The system cannot be activated if the radar sen‐  
sor is not correctly aligned, for example if it is  
damaged while parking.

Warning  
Acoustic signals  
General  
An intermittent sound indicates that the vehicle  
is approaching an object. For instance, if an ob‐  
ject is identified to the rear left of the vehicle, the  
acoustic signal is emitted from the rear left loud‐  
speaker.  
The vehicle's approach to an object is shown on  
the Control Display. Objects that are further away  
are already displayed before an acoustic signal is  
given.  
The shorter the distance to an object, the shorter  
the intervals become.  
The display appears as soon as PDC is activated.  
The recording range of the sensors is shown in  
green, yellow and red.  
A continuous tone sounds if the distance to a  
detected object is less than approximately  
20 cm, 8 in.  
Driving path lines are displayed for better estima‐  
tion of the space required.  
If there are objects in front of and behind the ve‐  
hicle at the same time, and they are at a distance  
of less than approximately 20 cm, 8 in, an alter‐  
nating continuous tone sounds.  
If the rear-view camera image is shown, it is pos‐  
sible to change over to PDC or, if required, to an‐  
other view with obstacle markings:

Safety notes  
WARNING  
The system does not relieve you of your per‐  
sonal responsibility to assess the traffic situa‐  
tion correctly. Due to system limitations, it can‐  
not respond independently and appropriately in  
all traffic conditions. There is a risk of accident.  
Adapt your driving style to the traffic conditions.  
Observe the traffic situation and intervene ac‐  
tively if the situation warrants it.  
Low objects already indicated, for example  
kerbs, may enter the sensors' blind areas be‐  
fore or after a continuous tone is given.  
The system does not take into account loads  
projecting beyond the outline of the vehicle.  
In some cases, parking spaces may be detec‐  
ted that are not suitable or suitable parking  
spaces may not be detected.  
WARNING  
Malfunction  
A Check Control message is shown.  
When the trailer tow hitch is in use, the driver  
assistance system could cause damage if its  
sensors are obstructed. There is a risk of acci‐  
dent or material damage. Do not use the driver  
assistance system during trailer operation or  
when using the trailer tow hitch, for example  
with a bicycle carrier.  
Park Assistant has failed. Have the system  
checked by a Service Partner of the manufac‐  
turer or another qualified Service Partner or a  
specialist workshop.  
The Safety Information for the Park Distance  
Control PDC, see page 207, and Park Assist, see  
page 215, also applies.  
Reversing assistant  
Principle  
The system supports the driver when reversing,  
for example when driving out of tight or blind  
parking spaces or narrow roads.  
Operating requirements  
To save the stretch of road, drive forwards  
without interruption.  
The vehicle saves the driving movements for the  
last stretch of road. The vehicle can reverse  
along this saved stretch with automated steering.  
A maximum of 50 metres/ 55 yards can be  
saved.  
To save the stretch of road, do not drive  
faster than 36 km/h/ 22 mph.  
The system takes over the steering when revers‐  
ing along the saved stretch.  
The stretch of road that is to be reversed  
along must be at least 30 cm/12 in wider than  
the vehicle.  
The driver is responsible for operating the accel‐  
erator pedal and the brake.  
General  
The reversing assistant uses the control func‐  
tions and the sensors of the Park Distance Con‐

CONTROLS  
Reversing with automated  
steering  
1. When the vehicle is stationary and the drive-  
ready state is switched on, engage reverse  
gear or press the Park Assistant button.  
System limits  
When you reach normal road traffic or if you  
suddenly encounter an obstacle, stop imme‐  
diately and take over control of the vehicle.  
The maximum speed when reversing is limi‐  
ted to approximately 9 km/h/ 6 mph.  
2. Tilt the Controller to the right.  
3. "Reversing Assistant"  
Manual transmission: if the maximum speed  
is exceeded, a warning is issued and the  
function may be cancelled.  
The system takes over the steering.  
4. Follow the instructions on the Control Display  
as applicable.  
The system limits for Park Assist and the  
Park Distance Control PDC also apply.  
5. Take your hands off the steering wheel and  
carefully drive off using the accelerator pedal  
and brake.  
Crossing traffic warning  
When reversing, pay attention to the vehicle  
surroundings and observe the Park Distance  
Control PDC information. Brake if necessary.  
Principle  
At blind exits or when leaving bay parking  
spaces, the system detects other road users ap‐  
proaching from the side earlier than is possible  
from the driver's seat.  
6. Stop when you reach normal road traffic at  
the latest and take over control of the vehicle,  
for example by engaging a forward gear.  
At the end of the saved stretch of road, a sig‐  
nal sounds and a message appears prompt‐  
ing you to take over control of the vehicle.  
General  
Cancelling the system  
The system automatically cancels in situations  
such as the following:  
If the driver grips the steering wheel or steers  
the vehicle.  
When a forward gear is engaged.  
When drive control systems or Driver Assis‐  
tance Systems are activated or intervening.  
Two radar sensors in the rear bumper monitor  
the area behind the vehicle.  
If the vehicle is stationary for several minutes.  
The system indicates when other road users are  
approaching.  
If the vehicle leaves the stored lane during re‐  
versing; for example, at the maximum steer‐  
ing angle.  
When the display on the Control Display is  
hidden by messages, for example due to in‐  
coming calls.
