These include, for example:
Rmultimedia data such as music, films or pho-
tos for playback in an integrated multimedia
system
Raddress book data for use in conjunction withan integrated hands-free system or an inte-
grated navigation system
Rnavigation destinations that have been
entered
Rdata about using Internet services
This data can be saved locally in the vehicle or is
located on a device that you have connected to
the vehicle. If this data is saved in the vehicle,
you can delete it at any time. This data is sent to third parties only at your request, particularly
when you use online services in accordance with
the settings that you have selected.
You can save and change comfort settings/
customizations in the vehicle at any time.
Depending on the piece of equipment in ques-
tion, these can include, for example:
Rsettings for the seat and steering wheel posi- tions
Rsuspension and climate control settings
Rcustomizations such as interior lighting
If your vehicle is equipped appropriately, you
can connect your smartphone or another mobile
terminal 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, for example:
Rgeneral vehicle status
Rposition 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.
Service provider
Wireless network connection
If your vehicle has a wireless network connec-
tion, it enables data to be exchanged between
your vehicle and other systems. The wireless
network connection is made possible by the
vehicle's own transmitter and receiver or by
mobile end devices that you have brought into
the vehicle (e.g. smartphones). Online functions
can be used via this wireless network connec-
tion. These include online services and applica-
tions/apps provided by the manufacturer or
other providers.
Services provided by the manufacturer
In the case of the manufacturer's online serv-
ices, the manufacturer describes the functions
in a suitable place and the associated informa-
tion subject to data protection legislation. Per-
sonal data can be used in order to provide online
services. The data exchange for this takes place
via a secure connection, e.g. with the manufac- turer's IT systems intended for the purpose. Col-
lecting, processing and using personal data
beyond the provision of services is permitted
only on the basis of a statutory permit or decla-
ration of consent.
You can usually activate and deactivate the serv-
ices and functions (sometimes subject to a fee).
In many cases, this also applies to the vehicle's
entire data connection. This does not include
legally prescribed functions and services such
as the "E-Call" emergency call system.
Services from third parties
If it is possible to use online services from other
providers, these services are the responsibility
of the provider in question and subject to that
provider's data protection conditions and terms
of use. The manufacturer has no influence over
the content exchanged here.
For this reason, please ask the service providerfor information about the type, extent and pur-
pose of the collection and use of personal data
when services are provided by third parties.

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
only parts which are relatively easily deformed
are affected and the rate of deceleration is not
high. Conversely, air bags may be deployed eventhough the vehicle suffers only minor deforma-
tion. This is the case if, for example, very rigid
vehicle parts such as longitudinal body mem-
bers are hit, and sufficient deceleration occurs
as a result.
If the restraint system control unit detects a side
impact or if the vehicle rolls over, the applicable
components of the restraint system are
deployed independently of each other depend-
ing on the apparent type of accident.
RSide impact air bag and pelvis air bag on the
side on which an impact occurs, independent
from the Emergency Tensioning Device and
seat belt usage
The side impact air bag on the front-
passenger side deploys under the following
conditions:
-the OCS system detects that the front-
passenger seat is occupied or
-the seat belt buckle tongue is engaged in
the belt buckle of the front-passenger seat
RWindow curtain air bag on the side of impact,
independently of the use of the seat belt and
independently of whether the front-
passenger seat is occupied
REmergency Tensioning Devices, if the system
determines that deployment can offer addi-
tional protection in this situation
RWindow curtain air bags on the driver's and
front-passenger side in certain situations
when the vehicle rolls over, if the system
determines that deployment can offer addi-
tional protection to that provided by the seat
belt
iNot all air bags are deployed in an accident.
The different air bag systems work independ- ently of each other.
How the air bag system works is determined
by the severity of the accident detected,
especially the vehicle deceleration or accel-
eration and the apparent type of accident:
RFrontal collision
RSide impact
RRollover
Automatic measures after an acci-
dent
Immediately after an accident, the following
measures are implemented, depending on the
type and severity of the impact:
Rthe hazard warning lamps are activated
Rthe emergency lighting in the interior is acti-
vated
Rthe vehicle doors are unlocked
Rthe front side windows are lowered
Rair-recirculation mode is activated
Rclimate control is switched off
Rthe engine is switched off and the fuel supply
is cut off
Children in the vehicle
Important safety notes
Accident statistics show that children secured
in the rear seats are safer than children secured
in the front-passenger seat. For this reason,
Mercedes-Benz strongly advises that you install
a child restraint system on a rear seat. Children
are generally better protected there.
If a child younger than twelve years old and
under 5 ft (1.50 m) in height istraveling in the
vehicle:
Ralways secure the child in a child restraint
system suitable for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
Rbe sure to observe the instructions and safety
notes in this section in addition to the child
restraint system manufacturer's installation
instructions.
Ralways observe the instructions and safety
notes on the "Occupant classification system (OCS)". (
Ypage 52)
GWARNING
If you leave children unsupervised in the vehi-
cle, they could set it in motion by, for example:
Rrelease the parking brake.
Rshift the automatic transmission out of the
parking position P.
Rstart the engine.

Useful information
This Operator's Manual describes all models as
well as standard and optional equipment of your
vehicle that were available at the time of going
to print. Country-specific variations are possi-
ble. Note that your vehicle may not be equipped
with all of the described functions. This also
applies to systems and functions relevant to
safety.
Read the information on qualified specialist
workshops (
Ypage 31).
Overview of climate control systems
Important safety notes
Observe the recommended settings on the fol-
lowing pages. Otherwise, the windows could fog
up.
To prevent the windows from fogging up:
Ronly switch off climate control briefly
Ronly switch on air-recirculation mode briefly
Rfor vehicles with air-conditioning system or
dual-zone automatic climate control, switch
on the "Cooling with air dehumidification"
function
Rfor vehicles with dual-zone automatic climate
control, switch on the windshield defrosting
function briefly, if requiredClimate control regulates the temperature and
the humidity in the vehicle interior and filters
undesirable substances from the air.
Climate control is only operational when the
engine is running. The system only functions
optimally when the side windows are closed.
Ventilate the vehicle for a brief period during
warm weather. In order to cool the vehicle more
rapidly, switch climate control to air-recircula-
tion mode briefly. This will speed up the cooling
process and the desired interior temperature
will be reached more quickly.
The integrated filter can filter out most particles
of dust and completely filters out pollen. In vehi-
cles with dual-zone automatic climate control,
gaseous pollutants and odors will also be
reduced. A clogged filter reduces the airflow into
the vehicle interior. For this reason, you should
always observe the interval for replacing the fil- ter, which is specified in the Maintenance Book-
let. As the interval between changes depends on
environmental conditions, e.g. heavy air pollu-
tion, the interval may be shorter than stated in
the Maintenance Booklet.

ROnly use air-recirculation mode briefly, e.g. if
there are unpleasant outside odors or when in a tunnel. The windows could otherwise fog up
as no fresh air is drawn into the vehicle in air-
recirculation mode. The indicator lamp in the

switch comes on when the function is
switched on.
During automatic engine switch-off, the climate
control system only operates at a reduced capa-
city. Further information on the automatic
engine switch-off can be found under "ECO
start/stop function" (
Ypage 125).
