Tyre Pressure Monitor TPM
Principle The system monitors the tyre pressure in the
four fitted tyres. The system warns if the infla‐
tion pressure in one or more tyres has fallen
considerably. To do this, the sensors in the
tyre valves measure the tyre pressure and tyre
temperatures.
Note
To operate the system, also follow the other
information and notes under tyre inflation pres‐
sure, see page 175.
Operating requirements For the system, a reset must have been made
with the correct tyre inflation pressure, other‐
wise reliable signalling of a flat tyre cannot be assured.
Reset the system after adjusting the tyre pres‐
sure to a new value and after a tyre or wheel
change.
Always use wheels with TPM electronics to
guarantee the system functions without errors.
Status display
The current status of the Tyre Pressure Moni‐
tor TPM can be shown on the Control Display,
for example whether the TPM is active.
On the Control Display:1."Vehicle information"2."Vehicle status"3. "Tyre Pressure Monitor (RDC)"

The system cannot detect a flat tyre. The rea‐
sons for this are:▷System reset is performed.▷Malfunction.
Additional information
The current tyre inflation pressures and, de‐
pending on the model, tyre temperatures are
also displayed in the status control display.
The values shown are current values and may
change due to the effect of driving mode or
weather conditions.

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

Front-end collision warning
with city braking function
Principle The system can help avoid accidents. If an ac‐
cident cannot be avoided, the system helps to
reduce the collision speed.
The system warns of the possible risk of colli‐
sion and brakes automatically, as necessary.
The automatic braking intervention is done
with limited force and duration.
The system is controlled by a camera in the
area of the rear-view mirror.
The front-end collision warning is also avail‐
able if the Cruise Control is disabled.
When deliberately approaching a vehicle, the
approach control warning and braking inter‐
vention are activated later to avoid unjustified
system responses.
General
The system warns from approximately 5 km/h,
approximately 3 mph in two stages of any risk
of collision with vehicles. The timing of these
warnings may vary depending on the current
driving situation.
Up to approximately 60km/h, 35 mph.
Detection range
Objects are taken into account if they are de‐
tected by the system.

Warning with braking function
Display
If there is a risk of collision with a detected ve‐
hicle, a warning symbol is shown in the instru‐
ment cluster and in the Head-Up Display.SymbolMeasureSymbol illuminates red: advance
warning.
Increase braking and distance.Symbol flashes red and an acoustic
signal sounds: acute warning.
System indicates that you must
brake and/or manoeuvre the vehicle
yourself.
Advance warning
An advance warning is shown, for example if a
danger of collision is anticipated or there is a very short distance to a vehicle ahead.
The driver must intervene personally if there is
an advance warning.
Acute warning with braking function
An acute warning is shown in the event of an
immediate collision if the vehicle approaches
an object with relatively high differential speed.
The driver must intervene personally if there is
an acute warning. If necessary, the driver is as‐
sisted by slight automatic brake intervention if
there is a risk of collision.
An acute warning can be triggered even with‐
out a previous advance warning.
Brake interventionThe 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 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.
Seite 113SecurityControls113

Detection range
The detection zone in front of the vehicle con‐
sists of two parts:
▷Central zone, arrow 1, directly in front of
the vehicle.▷Extended zone, arrow 2, at right and left.
There is a risk of collision if persons are in the
central zone. A warning is only given of per‐
sons in the extended zone if they are moving in
the direction of the central zone.

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.
