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.

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 status is displayed.
Status control display The tyre and system status is denoted by the
wheel colour and some text on the Control Dis‐
play.
All wheels green
System is active and is warning about the tyre
inflation pressures stored during the last reset.
One wheel yellow
A flat tyre or major loss of tyre inflation pres‐
sure in the tyre shown.
All wheels yellow
A flat tyre or major loss of tyre inflation pres‐
sure in several tyres.
Wheels grey
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.
Running reset Reset the system after adjusting the tyre pres‐
sure to a new value and after a tyre or wheel
change.
On the Control Display and on the vehicle:
1."Vehicle information"2."Vehicle status"3. "Perform reset"4.Start the engine – do not drive off.5.Resetting tyre pressure: "Perform reset".6.Drive off.
The wheels are shown grey and the status ap‐
pears on the display.
After driving for a short time over 30 km/h,
19 mph the set tyre inflation pressures are ac‐

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
