nection in the vehicle, which is approved for
your vehicle by Mercedes-Benz. G
WARNING
Objects in the driver's footwell can restrict the pedal travel or obstruct a depressed pedal.
The operating and road safety of the vehicle is
jeopardized. There is a risk of an accident.
Make sure that all objects in the vehicle are
stowed correctly, and that they cannot enter
the driver's footwell. Install the floormats
securely and as specified in order to ensure
sufficient clearance for the pedals. Do not use loose floormats and do not place floormats on
top of one another.
! If the engine is switched off and equipment
on the diagnostics connection is used, the
starter battery may discharge.
Connecting equipment to the diagnostics con-
nection can lead to emissions monitoring infor-
mation being reset, for example. This may lead
to the vehicle failing to meet the requirements of the next emissions test during the main inspec-
tion. Qualified specialist workshop

! Observe the notes in this Operator's Manual
regarding the correct operation of your vehi-
cle and possible damage to the vehicle. Dam-
age to the vehicle which is caused by violation
of these notes is not covered by the
Mercedes-Benz implied warranty or the new

The QR codes are secured in the fuel filler flap
and on the opposite side on the B-pillar. In the
event of an accident, rescue services can use
the QR code to quickly find the appropriate res-
cue card for your vehicle. The current rescue
card contains the most important information
about your vehicle in a compact form, e.g. the
routing of the electric cables.
You can find more information at
www.mercedes-benz.de/qr-code. Data stored in the vehicle
Electronic control units
There are electronic control units installed in
your vehicle. Some of these are necessary for
your vehicle to operate safely, while some offer
support during driving (driver assistance sys-
tems). In addition, your vehicle offers comfort
and entertainment functions that are also made possible by electronic control units. Electronic control units contain data storage
systems that can temporarily or permanently
save technical information concerning the vehi-
cle's condition, component stress and mainte-
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 manufacturer
needs 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. Data stored in the vehicle
29Introduction Z

For your own safety and that of your front
passenger, it is important that you have
deployed air bags replaced and faulty air bags
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 41)
R the seat belt buckle tongue has engaged in
the belt buckle of the respective seat
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 as well as driver's and front-
passenger knee bags
R Side impact air bag and head bag, if the sys-
tem determines 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
disabled or enabled. 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 41).
Your vehicle has two-stage front air bags. At the
first deployment threshold the front air bag fills with gas. If the second deployment threshold isthen reached within a few milliseconds, the front
air bag is filled with the maximum quantity of
gas.
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- Occupant safety

Information regarding technical data
i The data stated here specifically refers to a
vehicle with standard equipment. Consult an
authorized Mercedes-Benz Center for the
data for all vehicle variants and trim levels. Vehicle electronics
Tampering with the engine electron-
ics
! Have the engine electronics and associated
parts, such as control units, sensors, actuat-
ing components or electric cables serviced
only at a qualified specialist workshop. Vehi-
cle components may otherwise wear more
quickly and the vehicle's operating permit
may be invalidated. Installing wireless devices and mobile
phones G
WARNING
The electromagnetic radiation from two-way
radios can interfere with the vehicle electron-
ics if two-way radios are manipulated or ret-
rofitted incorrectly. This could jeopardize the
operating safety of the vehicle. There is a risk of an accident.
You should have all work on electrical and
electronic components carried out at a quali-
fied specialist workshop. G
WARNING
If you incorrectly operate two-way radios in
the vehicle, the electromagnetic radiation
may interfere with the vehicle electronics, for example if:
R the two-way radio is not connected to an
exterior antenna
R the exterior antenna is not correctly moun-
ted or is not low-reflection
This could jeopardize the operating safety of
the vehicle. There is a risk of an accident. Have the low-reflection exterior antenna
installed at a qualified specialist workshop.
Always connect two-way radios to the low-
reflection exterior antenna when operating in the vehicle.
! The operating permit may be invalidated if
the instructions for installation and use of
two-way radios are not observed.
In particular, the following conditions must be
complied with:
R only approved wavebands may be used.
R observe the maximum permissible output
in these wavebands.
R only approved antenna positions may be
used.
Excessive levels of electromagnetic radiation
may cause damage to your health and the health
of others. Using an exterior antenna takes into
account current scientific discussions relating
to the possible health hazards that may result
from electromagnetic fields.
The following can be used in the vehicle without restrictions:
R two-way radios with a maximum transmission
output of up to 100 mW
