System limits
The automatic driving lights control is no sub‐
stitute for your individual judgement of when it
is necessary to switch on the lights.
The sensors are unable, for instance, to recog‐
nise fog or hazy weather. In such situations,
switch on the lights manually to avoid any
safety risk.
Daytime driving lights Switch position:

The daytime driving lights illuminate with the
ignition switched on.
Activating/deactivating
In some countries daytime driving lights are
compulsory, which is why the daytime driving
lights cannot be deactivated.

Adaptive HeadlightsPrinciple
Adaptive Headlights is a variable headlight
control system that makes it possible to illumi‐
nate the road surface responsively.
The beams from the headlights follow the road
ahead on the basis of the steering angle and
other parameters.
Depending on the speed, the variable light dis‐
tribution ensures even better illumination of
the roadway.
The light distribution is automatically adapted
to the speed. The city light is switched on if the
speed of 50 km/h, approx. 30 mph is not ex‐
ceeded while accelerating or if the speed of
40 km/h, approx. 25 mph is undercut while
braking. The motorway light is switched on at a speed higher than 110 km/h, 68 mph after ap‐
proximately 30 seconds or as of a speed of
140 km/h, 87 mph.
Activating Switch position
with the ignition switched
on.
So as not to dazzle oncoming vehicles, the
adaptive cornering light does not swivel to the
driver's side when stationary.
A cornering light is activated automatically de‐
pending on the steering angle or use of the
turn indicators.
The cornering light may be switched on when
driving in reverse, irrespective of the steering
angle.
Malfunction
A Check Control message is displayed.
Adaptive Headlights are faulty or have failed.
Have the system checked as soon as possible.
High-beam assistance
Principle When low-beam headlights are switched on,this system automatically switches the high-
beam headlights on and off or fades out the
areas which dazzle oncoming vehicles. This
process is controlled by a camera on the front
of the rear-view mirror. It ensures that the
high-beam headlights are switched on when‐
ever the traffic situation allows. You can also
control the lights yourself at any time and
switch them on and off as usual. The high-
beam headlights are not switched on by the
system in the low speed range.

Notes on optimum protective effect of
the airbag
WARNING
If the seat position is wrong or the de‐
ployment area of the airbag is impaired, the air‐
bag system cannot provide the intended pro‐
tection, or may cause additional injuries when
it deploys. Danger of injury or life. Comply with
these notes for optimum protective effect.◀▷Keep your distance from the airbags.▷Make sure that vehicle occupants keep
their head away from the side airbag.▷Always grip the steering wheel on the
steering wheel rim. Keep you hands in the
3 o'clock and 9 o'clock positions to reduce
the risk of injury to hands or arms when the
airbag deploys.▷Make sure that the front-seat passenger is
sitting correctly, in other words with feet or
legs in the footwell, not resting on the
dashboard.▷Do not position any other persons, pets or
objects between the airbags and persons.▷Never attach any material to the airbag
covers with adhesive; never place material
over them or modify them in any way.▷Keep the dashboard and windscreen in the
area of the passenger's side free, for exam‐
ple do not attach adhesive foil or covers
and do not fit brackets for navigation devi‐
ces or mobile telephones.▷Do not use the front airbag cover on the
front passenger's side as a tray.▷Do not fit seat covers, cushions or other
objects not specifically suitable for seats
with integral side airbags to the front seats.▷Do not hang items of clothing such as
coats or jackets over the backrests.▷Do not modify individual components of
the system or its wiring in any way. This
also applies to the covers of the steering
wheel, the dashboard and seats.▷Do not dismantle the airbag system.
Even if all these notes are complied with, de‐
pending on the circumstances in which an ac‐
cident occurs, certain injuries as a result of
contact with the airbag cannot be entirely ruled
out.
The noise caused by the deployment of an air‐
bag may lead to temporary hearing loss for ve‐
hicle occupants sensitive to noise.
Operational readiness of the airbag
system
Notes WARNING
Individual components of the airbag sys‐
tem can be hot after triggering. Danger of in‐ jury. Do not touch individual components.◀
WARNING
Work carried out incorrectly can lead to a
failure, a malfunction or accidental triggering of
the airbag system. If there is a malfunction, the
airbag system might not trigger as intended in
an accident, in spite of the accident being of
the appropriate severity. Danger of injury or
life. Have the airbag system tested, repaired or
removed and scrapped by a Service Partner or a qualified specialist workshop.◀
Correct function When the ignition is switched on, the
warning light in the instrument cluster
briefly illuminates in order to show the
functional readiness of the entire airbag sys‐
tem and the belt tensioner.
Airbag system disrupted

cepted as target values. The reset is run auto‐
matically while the vehicle is in motion.
After a successfully concluded reset, the
wheels are shown in green on the Control Dis‐
play and "Tyre Pressure Monitor (RDC)
active." is shown.
You can interrupt your drive at any time. Reset
resumes automatically when you continue
your journey.
Message if tyre inflation pressure is
low
The yellow warning lamp is illuminated.
A Check Control message is shown.▷There is a flat tyre or substantial
loss of tyre pressure.▷No reset has been done to the system.
Consequently, the system warns of the
tyre pressures of the last reset.1.Reduce your speed and carefully stop the
vehicle. Avoid violent or sudden braking
and steering manoeuvres.2.Determine which wheel is damaged. Do
this by checking the tyre inflation pres‐
sures with the aid of the Mobility System.
Correcting the tyre inflation pressure3.Remedy the flat tyre with the Mobility Sys‐
tem or replace the damaged wheel.
When there is a message that the tyre inflation
pressure is low, the Dynamic Stability Control
DSC may be switched on.
Message with required tyre inflation
pressure test
In such situations, a check control message is
displayed:
▷System has detected a wheel change, but
no reset has been run.▷Filling was not performed according to the
regulations.▷The tyre inflation pressure has dropped
compared to the last confirmation.If that is the case:▷Check the tyre pressure and adjust as nec‐
essary.▷Reset the system after a wheel change.
System limits
The system is not working correctly if no reset
has been run, for example, a flat tyre is repor‐
ted in spite of the correct tyre inflation pres‐
sure.
Tyre inflation pressure depends on the tem‐
perature of the tyre. By increasing tyre temper‐
ature, for example, when driving or with solar
radiation, the tyre inflation pressure increases.
Tyre inflation pressure decreases if the tyre
temperature drops. Through this behaviour, a
warning may be triggered if there are major
temperature drops, due to the given warning
limits.
No warning can be given by the system of ex‐
treme, sudden tyre failure caused by external
factors.
Malfunction The yellow warning lamp flashes and is
then illuminated continuously. A Check
Control message is shown. No flat
tyres or loss of tyre pressure can be detected.
This may indicate one of the following:
▷Wheel without TPM electronics is fitted:
have the vehicle checked by a Service
Partner or a qualified specialist workshop if
necessary.▷Malfunction: have the system checked by a
Service Partner or a qualified specialist
workshop.▷TPM has not completed a reset. Run a re‐
set of the system again.▷Fault due to systems or devices with the
same frequency: the system is automati‐
cally reactivated upon leaving the field of
interference.Seite 108ControlsSecurity108

Runflat indicator RPA
Principle The system identifies a loss of tyre pressure
by comparing the speeds of rotation of the in‐
dividual wheels while the vehicle is in motion.
If a tyre loses pressure, its diameter changes.
This in turn alters the rotational speed of the
corresponding wheel. This is detected and re‐
ported as a flat tyre.
The system does not measure the tyre pres‐
sures as such.
Operating requirements
The system must have been initialised with
correct tyre inflation pressure, otherwise relia‐
ble signalling of a flat tyre cannot be assured.
Each time the tyre pressure is adjusted or a
tyre or wheel is changed, initialise the system
again.
Status display The current status of the runflat indicator can
be shown on the Control Display, for example
whether the runflat indicator is active.
On the Control Display:1."Vehicle information"2."Vehicle status"3. "Flat Tyre Monitor (RPA)"
The status is displayed.
Initialising
On initialisation, the current tyre pressures are
stored as a reference for detection of a flat tyre. The initialisation is started by confirming
the correct tyre inflation pressures.
When driving with snow chains fitted, do not
initialise the system.
On the Control Display:
1."Vehicle information"2."Vehicle status"3. "Perform reset"4.Start the engine – do not drive off.5.Start the initialisation with "Perform reset".6.Drive off.
Initialising is completed while the vehicle is in
motion; this process can be interrupted at any
time.
Initialising resumes automatically when you
continue your journey.
Message of a flat tyre The yellow warning lamp is illuminated.
A Check Control message is shown.
There is a flat tyre or substantial loss of
tyre pressure.
1.Reduce your speed and carefully stop the
vehicle. Avoid violent or sudden braking
and steering manoeuvres.2.Determine which wheel is damaged. Do
this by checking the tyre inflation pres‐
sures with the aid of the Mobility System. If
all tyres are inflated to the correct pres‐
sures, the runflat indicator might not have
been initialised. In this case initialise the
system.3.Remedy the flat tyre with the Mobility Sys‐
tem or replace the damaged wheel.
System limits
A natural, even loss of tyre pressurein all four
tyres that occurs over time is not detected.
Consequently, check the tyre inflation pres‐
sure at regular intervals.
No warning can be given in the event of sud‐
den tyre failure caused by external factors.
In the following situations, the system could be
slow to respond or operate incorrectly:
▷If the system has not been initialised.▷Journey on snow-covered or slippery sur‐
faces.Seite 109SecurityControls109

speed until it comes to a stop.
Manual gearbox: When brakes are engaged
until it comes to a stop, the engine may shut
off.
There will only be brake intervention if Dy‐
namic Stability Control, DSC is activated and
M Dynamic Mode MDM is not activated.
Braking can be discontinued either by pressing
the accelerator pedal or by actively moving the
steering wheel.
Detection of objects can be restricted. Limita‐
tions of the detection range and functional re‐
strictions are to be considered.

The detection ability of the system is limited.
For this reason, system responses may be
missing or delayed.
It is possible that the following are not detec‐
ted:▷Slow-moving vehicle when approaching at
high speed.▷Vehicles suddenly cutting in or decelerat‐
ing heavily.▷Vehicles with unusual rear view.▷Two-wheeled vehicles ahead.
Restrictions of the function
The function can be restricted, for example in
the following situations:
▷In thick fog, rain, spray or snowfall.▷On sharp bends.▷When restricting or deactivating vehicle
stability control systems, for example DSC
OFF.▷If the field of view of the camera in the mir‐
ror is soiled or covered.▷Up to 10 seconds after starting the engine
using the start/stop button.▷During the calibration process of the cam‐
era immediately after the vehicle is sup‐
plied.▷When there is sustained glare effect due to
light opposite, for example the sun low in
the sky.
Sensitivity of the warnings
The greater the sensitivity of the warning set‐
tings, for example warning time, the more
warnings will be displayed. As a result, there
may be an increased number of incorrect
warnings.
Person warning with city
braking function
Principle The system can help to avoid accidents with
pedestrians.
The system warns of the possible risk of colli‐
sion with pedestrians in the urban speed area
and also contains a braking function.
The system is controlled by the camera in the
area of the rear-view mirror.
General
The system warns with sufficient brightness
from approx. 10 km/h, approx. 6 mph up to ap‐
prox. 60 km/h, approx. 35 mph of any risk of
collision with pedestrians and supports this by
briefly applying the brakes before a collision.
Here, persons are taken into account if they
are located within the detection range of the
system.

Warning with braking function
Display
If there is a risk of collision with a detected per‐
son, a warning symbol is shown in the instru‐
ment cluster and in the head-up display.
Red symbol is displayed and an acous‐
tic warning sounds.
Take action yourself immediately, by braking
or swerving.
Brake intervention
The warning requires to take action yourself.
Maximum braking force is used during a warn‐
ing. In order for braking force support to be
used, it is necessary for the brake to be
pressed sufficiently quickly and powerfully. In
addition, the system may also support with a
small amount of braking if there is the risk of a
collision. The vehicle can be braked at low
speed until it comes to a stop.
Manual gearbox: When brakes are engaged
until it comes to a stop, the engine may shut
off.
There will only be brake intervention if Dy‐
namic Stability Control, DSC is activated and
M Dynamic Mode MDM is not activated.
Braking can be discontinued either by pressing
the accelerator pedal or by actively moving the
steering wheel.
Detection of objects can be restricted. Limita‐
tions of the detection range and functional re‐
strictions are to be considered.
System limits
Detection range
The detection capacity of the camera is limi‐
ted.

Lane departure warning
Principle This system warns if the vehicle leaves the
lane, when the vehicle is on roads with lane
markings and travelling above a given speed.
Depending on country version, this speed is
between 55 km/h, approximately 35 mph and
70 km/h, approximately 45 mph.
When switching on the system below this
speed, a message is displayed in the instru‐
ment cluster.
