In the following situations, the indicator light in the outside mirror indicates avehicle in the “blind spot”.
▶ You vehicle

is being overtaken by vehicle
A
» Fig. 275 .
▶ Your vehicle
C
overtakes the vehicle
D
at a greater speed of max. 10
km » Fig. 276 . If the speed during the overtaking is even higher, then there is
no warning by the warning light.
The warning display is always in the exterior mirror on the side of the vehicle where a vehicle is detected in the “blind spot”.
The greater the speed difference between the two vehicles, the earlier the
warning (by means of the warning light) regarding the vehicle that is overtak-
ing you takes place.
Two warning levels
light up - a vehicle has been detected in the “blind spot”.
flash - a vehicle has been detected in the “blind spot” and the turn signal is
switched on .
An advanced warning for vehicles with Lane Assist
flash also if the steering wheel is turned in the direction of the vehicle in
the “blind spot” . Therefore the Lane Assist » page 254 must be enabled and
the boundary line between the vehicles detected.
If in this case your vehicle indicates crossing the boundary line, with a short vi-
bration of the steering wheel.
NoteThe brightness of the indicator light is dependent on the setting of the ve-
hicle lighting. With the low or high beam on the brightness of the light will be
lower.

WARNING (Continued)■During manoeuvring, always observe the movement of the trailer and if
neccesary cancel the manoeuvring autonomously to prevent accidents or
damage to the vehicle and the trailer.■
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 parking manoeuvres on loose or slippery surfaces (gravel, snow,
ice, etc.) it is possible to stray from the calculated road. Therefore, use the
system with extreme caution in such situations.
CAUTION
■ The trailer position is evaluated by the rear camera based on the bending an-
gle of the drawbar and the steering movement carried out by the system. For
this reason, the drawbar must not be obstructed by external influences.■
The rear camera lens must not be contaminated, otherwise the system may
be unavailable or the system function my be significantly impaired.
Note
■ We recommend performing the parking at a safe speed of up to about 5
km/h.■
The parking process can be terminated at any time by pressing the button
» Fig. 294 on page 238 or by a steering intervention.
■
The correct system function can only be ensured if a one- or two-axle trailer
is hitched without steered axle.
Operating principle

The system is activated.
The parking aid is activated.
The driver's door and the boot lid are fully closed.

The trailer is not veering too much.
Determining the drawbar length
The system must know the drawbar length in order that the driver is offered
the maximum possible setting angle with respect to the target position of the
trailer.
The system needs some turning manoeuvres or cornering with a hitched trailer
in order to determine the drawbar length.

238Driving
After starting the system, the current speed is set as the speed limit, the
warning light lights up in the instrument cluster.
Exceeding the speed limit during the regulation
If, during the control, it is necessary to exceed the speed limit (e.g. to over-
take), the accelerator pedal must be pressed fully.
When exceeding the speed limit (e.g. driving down a hill), an acoustic signal
sounds and the warning light
flashes in the instrument cluster.
The regulation is resumed once the speed has fallen below the set limit.

Regulation according to the vehicle in the adjacent lane
During regulation your vehicle may be regulated according to the vehicle in the
adjacent lane.
This could occur at speeds above about 80 km/h when your vehicle is moving
faster than the vehicle in the adjacent lane on the driver's side. The display
shows the detected vehicle is in the adjacent lane.

Adaptive Chassis Control (DCC)
Read and observe
on page 251 first.
The adaptive chassis control (following known as DCC) provides the ability toadjust the shock characteristics for the sporty, normal or comfortable driving
when the corresponding control mode is selected.
The DCC evaluates steering response and road conditions while driving contin-
uously and adjusts the suspension behaviour within the selected driving mode
accordingly.
Mode

ABCProactive passenger protection (Crew Protect Assist)
Introduction
This chapter contains information on the following subjects:
Function
253
ProActive passenger protection (following known as system) increases pas-
senger protection in the front seats in situations that could lead to vehicle im-
pact or overturning.
WARNINGPlease take note of the general points relating to the use of assistance
systems » page 215, in section Introduction .
Note
■
The system component service life is monitored electronically. Further infor-
mation » page 37 , Safety systems .■
If the front passenger front airbag is deactivated, the belt tensioning func-
tion for the front passenger seat is switched off.
Function
Read and observe
on page 253 first.
In critical driving situations (e.g. during emergency braking or a sudden changein direction), the following steps can be taken separately or combined in order
to reduce the risk of serious injury.
▶ The front passenger's and driver's seatbelts, if worn, are automatically ten-
sioned closely over the body.
▶ Opened door windows in the front doors are automatically closed up to a gap
of about 5 cm from the edge.
▶ The sliding/tilting roof is closed.
Once the critical driving situation has passed, the tension on the seatbelts will
be released again.
The system operates at two levels of protection.
The first level of protection
The system already intervenes in situations that may occur during dynamic
driving. As a result, this primarily helps to keep the driver and the passenger in
the correct seated position.

The system intervenes when approaching the right-hand boundary lane.
Adaptive tracking takes place.
The system can intervene when the following basic conditions are present. The system is activated.
The vehicle is travelling at more than around 65 km/h 1)
.
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 (e.g. when turning), no steering intervention takes place when the vehicle approaches the boundary line. The system re-
gards the situation as an intended lane change.
Warning lights in the instrument cluster The system is active, but not ready to intervene.
The system is active and ready to intervene or is currently intervening.
Adaptive lane assist
Adaptive tracking helps to keep the vehicle in the position between the boun-
dary lines selected by the driver, by means of steering intervention.
If the position within the lane is changed, the system quickly adapts and holds
the newly-selected position.
Steering wheel vibrations
In the following situations, it may occasionally be the case that due to the
steering wheel vibrations the syst4em indicates that a driver steering inter-
vention is required.
▶ The system is not able to keep the vehicle by a within the lane due to a
steering intervention.
▶ During an intense system-related steering intervention, the system suddenly
cannot recognize the boundary lines.WARNINGThe system function may be restricted if, for example there is danger due
to ruts on a downhill road or in a crosswind.1)
