nance requirements as well as technical events
and malfunctions.
This information generally documents the con-
dition of a component, a module, a system or the
surroundings, such as:
R Operating states of system components (e.g.
fill levels, battery status, tire pressure)
R Status messages concerning the vehicle or its
individual components (e.g. wheel rpm/
speed, deceleration, lateral acceleration, indi- cation of whether seat belts are fastened)
R Malfunctions and defects in important system
components (e.g. lights, brakes)
R Information about events leading to vehicle
damage
R System responses in special driving situa-
tions (e.g. air bag deployment, intervention of
stability control systems)
R Ambient conditions (e.g. temperature, rain
sensor)
In addition to performing the actual control unit
function, this data is used by manufacturers to
detect and rectify malfunctions and to optimize vehicle functions. Most of this data is volatile
and processed only in the vehicle itself. Only a
small part of the data is stored in event or mal-
function memories.
When you use services, the technical data from
the vehicle can be read out by service network
employees (e.g. workshops, manufacturers) or
third parties (e.g. breakdown services). Services
can include repair services, maintenance pro-
cesses, warranty cases and quality assurance
measures. The data are read out via the con-
nection for the diagnostics connection in the
vehicle, which is required by law. The relevant
offices in the service network or third parties
collect, process and use the data. This data
documents the vehicle's technical states, is
used to help in finding malfunctions and improv-
ing quality and is sent to the manufacturer
where necessary. In addition, the manufacturer is subject to product liability. The manufacturerneeds technical data from vehicles for this pur-
pose.
Malfunction memories in the vehicle can be
reset by a service center during repair or service
work.
You can incorporate data into the vehicle's com- fort and infotainment functions yourself as part
of the selected equipment. These include, for example:
R Multimedia data such as music, films or pho-
tos for playback in an integrated multimedia
system
R Address book data for use in conjunction with
an integrated hands-free system or an inte-
grated navigation system
R Navigation destinations that have been
entered
R Data about using Internet services
This data can be saved locally in the vehicle or
located on a device that you have connected to
the vehicle (e.g. smartphone, USB memory stick or MP3 player). If this data is saved in the vehi-
cle, you can delete it at any time. This data is
sent to third parties only at your request, par-
ticularly when you use online services in accord- ance with the settings that you have selected.
You can save and change comfort settings/
customizations in the vehicle at any time.
Depending on the equipment in question, these can include:
R Seat and steering wheel position settings
R Suspension and climate control settings
R Custom settings such as interior lighting
If your vehicle is equipped appropriately, you
can connect your smartphone or another mobile end device to the vehicle. You can control this by
means of the control elements integrated in the vehicle. The smartphone's picture and sound
can be output via the multimedia system. Spe-
cific items of information are also sent to your
smartphone.
Depending on the type of integration, this can
include:
R General vehicle information
R Position data
This allows the use of selected smartphone
apps, such as navigation or music player apps.
There is no additional interaction between the
smartphone and the vehicle, particularly active
access to vehicle data. The type of additional
data processing is determined by the provider of the app being used. Whether you can configure
settings for it and, if so, which ones, depends on
the app and your smartphone's operating sys-
tem. 32

repaired. This will help to make sure the air bags
continue to perform their protective function for the vehicle occupants in the event of a crash. G
WARNING
Emergency Tensioning Devices that have
deployed pyrotechnically are no longer opera- tional and are unable to perform their inten-
ded protective function. This poses an
increased risk of injury or even fatal injury.
Have pyrotechnically triggered Emergency
Tensioning Devices replaced immediately at a qualified specialist workshop.
An electric motor is used by PRE-SAFE ®
to trig-
ger the tightening of the seat belt in hazardous
situations. This procedure is reversible.
If Emergency Tensioning Devices are triggered
or air bags are deployed, you will hear a bang,
and some powder may also be released. The
0075 restraint system warning lamp lights up.
Only in rare cases will the bang affect your hear-
ing. The powder that is released generally does
not constitute a health hazard, but it may cause short-term breathing difficulties in people with
asthma or other respiratory problems. Provided
it is safe to do so, you should leave the vehicle
immediately or open the window in order to pre- vent breathing difficulties.
Air bags and pyrotechnic Emergency Tensioning
Devices (ETDs) contain perchlorate material,
which may require special handling and regard
for the environment. National guidelines must
be observed during disposal. In California, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm.
Method of operation During the first stage of a collision, the restraint
system control unit evaluates important physi-
cal data relating to vehicle deceleration or accel-
eration, such as:
R duration
R direction
R intensity
Based on the evaluation of this data, the
restraint system control unit triggers the Emer-
gency Tensioning Devices during a head-on or
rear-end collision. An Emergency Tensioning Device can only be
triggered, if:
R the ignition is switched on
R the components of the restraint system are
operational. You can find further information
under "Restraint system warning lamp"
(Y page 43)
R the seat belt buckle tongue has engaged in
the belt buckle of the respective front seat
The Emergency Tensioning Devices in the rear
passenger compartment are triggered inde-
pendently of the lock status of the seat belts.
If the restraint system control unit detects a
more severe accident, further components of
the restraint system are activated independ-
ently of each other in certain frontal collision
situations:
R Front air bags and driver's knee bag
R Window curtain air bag, if the system deter-
mines that deployment can offer additional
protection to that provided by the seat belt
Depending on the person in the front-passenger seat, the front-passenger front air bag is either
enabled or disabled. The front-passenger front
air bag can be deployed in an accident only if the PASSENGER AIR BAG OFF indicator lamp is off.
Observe the information on the PASSENGER AIR BAG indicator lamps (Y page 43).
Your vehicle has two-stage front air bags.
The activation threshold of the Emergency Ten- sioning Devices and the air bags is determined
by evaluating the rate of vehicle deceleration or
acceleration which occurs at various points in
the vehicle. This process is pre-emptive in
nature. Deployment should take place in good
time at the start of the collision.
The rate of vehicle deceleration or acceleration
and the direction of the force are essentially
determined by:
R the distribution of forces during the collision
R the collision angle
R the deformation characteristics of the vehicle
R the characteristics of the object with which
the vehicle has collided
Factors which can only be seen and measured
after a collision has occurred do not play a deci-
sive role in the deployment of an air bag. Nor do
they provide an indication of air bag deploy-
ment.
The vehicle can be deformed considerably, with- out an air bag being deployed. This is the case if Occupant safety

WARNING
Installing an unsuitable ball coupling may
overload the trailer tow hitch and the rear
axle. This is particularly likely in the case of
longer or differently angled ball couplings.
Consequently, the driving characteristics may
be significantly impaired and the trailer may
detach. This presents the risk of an accident
or even fatal injuries!
Install only a ball coupling that adheres to the permissible dimensions and is designed for
your intended purpose for towing a trailer. Do
not make any changes to the ball coupling or the trailer tow hitch.
You will find the values approved by the manu-
facturer on the vehicle identification plates and
those for the towing vehicle under "Technical
data" (Y page 367). G
WARNING
If the ball coupling is not installed correctly or not secured with the bolt provided and the
corresponding spring cotter, the trailer may
come loose. There is a risk of an accident.
Always install and secure the ball coupling as
described. Before every journey, ensure that
the ball coupling is secured with the bolt and
the corresponding spring cotter. G
WARNING
When the vehicle/trailer combination begins
to lurch, you could lose control of it. The vehi- cle/trailer combination could even rollover.
There is a risk of an accident.
On no account should you attempt to
straighten up the vehicle/trailer combination
