Introduction Z

Operating safety
Important safety notes
G WARNING
If you do not have the prescribed service/
maintenance work or any required repairs
carried out, this can result in malfunctions or
system failures. There is a risk of an accident.
Always have the prescribed service/mainte-
nance work as well as any required repairs
carried out at a qualified specialist workshop.
G WARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system. There is a risk
of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
G WARNING
Modifications to electronic components, their
software as well as wiring can impair their
function and/or the function of other net-
worked components. In particular, systems
relevant to safety could also be affected. As a
result, these may no longer function as inten-
ded and/or jeopardize the operating safety of
the vehicle. There is an increased risk of an
accident and injury.
Never tamper with the wiring as well as elec-
tronic components or their software. You
should have all work to electrical and elec-
tronic equipment carried out at a qualified
specialist workshop. ! There is a risk of damage to the vehicle if: R
the vehicle becomes stuck, e.g. on a high
curb or an unpaved road R
you drive too fast over an obstacle, e.g. a
curb, speed bumps or a pothole in the road R
a heavy object strikes the underbody or
parts of the chassis
In situations like this, the body, the under-
body, chassis parts, wheels or tires could be
damaged without the damage being visible.
Components damaged in this way can unex-
pectedly fail or, in the case of an accident, no
longer withstand the strain they are designed
to.
If the underbody paneling is damaged, com-
bustible materials such as leaves, grass or
twigs can gather between the underbody and
the underbody paneling. If these materials
come in contact with hot parts of the exhaust
system, they can catch fire.
In such situations, have the vehicle checked
and repaired immediately at a qualified spe-
cialist workshop. If on continuing your jour-
ney you notice that driving safety is impaired,
pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult a qualified spe-
cialist workshop.

The following text is reproduced as required of
all manufacturers under Title 49, Code of U.S.
Federal Regulations, Part 575 pursuant to the
National Traffic and Motor Vehicle Safety Act of
1966.
If you believe that your vehicle has a defect
which could cause a crash or could cause injury
or death, you should immediately inform the
National Highway Traffic Safety Administration
(NHTSA) in addition to notifying Mercedes-Benz
USA, LLC.
If NHTSA receives similar complaints, it may
open an investigation, and if it finds that a safety
defect exists in a group of vehicles, it may order
a recall and remedy campaign. However, NHTSA
cannot become involved in individual problems
between you, your dealer, or Mercedes-Benz
USA, LLC.
To contact NHTSA, you may call the Vehicle
Safety Hotline toll-free at 1-888-327-4236
(TTY: 1-800-424-9153 ); go to http://
www.safercar.gov ; or write to: Administrator,

QR codes for the rescue card
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 under
www.mercedes-benz.de/qr-code. Data stored in the vehicle
Data storage A wide range of electronic components in your
vehicle contain data memories.
These data memories temporarily or perma-
nently store technical information about: R
the vehicle's operating state R
incidents R
malfunctions
In general, this technical information docu-
ments the state of a component, a module, a
system or the surroundings.
These include, for example: R
operating conditions of system components,
e.g. fluid levels R
the vehicle's status messages and those of its
individual components, e.g. number of wheel
revolutions/speed, deceleration in move-
ment, lateral acceleration, accelerator pedal
position R
malfunctions and defects in important system
components, e.g. lights, brakes R
vehicle reactions and operating conditions in
special driving situations, e.g. air bag deploy-
ment, intervention of stability control sys-
tems R
ambient conditions, e.g. outside temperature
This data is of an exclusively technical nature
and can be used to: R
assist in recognizing and rectifying malfunc-
tions and defects R
analyze vehicle functions, e.g. after an acci-
dent R
optimize vehicle functions
The data cannot be used to trace the vehicle's
movements.
When your vehicle is serviced, technical infor-
mation can be read from the event data memory
and malfunction data memory.
Services include, for example: R
repair services R
service processes R
warranties R
quality assurance
The vehicle is read out by employees of the ser-
vice network (including the manufacturer) using
special diagnostic testers. More detailed infor-
mation is obtained from it, if required.Data stored in the vehicle 31
Introduction Z

After a malfunction has been rectified, the infor-
mation is deleted from the malfunction memory
or is continually overwritten.
When operating the vehicle, situations are con-
ceivable in which this technical data, in connec-
tion with other information (if necessary, under
consultation with an authorized expert), could
be traced to a person.
Examples include: R
accident reports R
damage to the vehicle R
witness statements
Further additional functions that have been con-
tractually agreed upon with the customer allow
certain vehicle data to be conveyed by the vehi-
cle as well. The additional functions include, for
example, vehicle location in case of an emer-
gency.
COMAND/mbrace If the vehicle is equipped with COMAND or
mbrace, additional data about the vehicle's
operation, the use of the vehicle in certain sit-
uations, and the location of the vehicle may be
compiled through COMAND or the mbrace sys-
tem.
For additional information please refer to the
COMAND User Manual or the Digital Owners
Manual and/or the mbrace Terms and Condi-
tions.
Event data recorders This vehicle is equipped with an event data
recorder (EDR). This vehicle is equipped with an
event data recorder (EDR). The main purpose of
an EDR is to record, in certain crash or near
crash-like situations, such as an air bag deploy-
ment or hitting a road obstacle, data that will
assist in understanding how a vehicle's systems
performed. The EDR is designed to record data
related to vehicle dynamics and safety systems
for a short period of time, typically 30 seconds
or less.
The EDR in this vehicle is designed to record
such data as: R
How various systems in your vehicle were
operating R
Whether or not the driver and passenger
safety belts were buckled/fastened R
How far (if at all) the driver was depressing the
accelerator and/or brake pedal and R
How fast the vehicle was traveling.
These data can help provide a better under-
standing of the circumstances in which crashes
and injuries occur. NOTE: EDR data are recorded
by your vehicle only if a non-trivial crash situa-
tion occurs; no data are recorded by the EDR
under normal driving conditions and no personal
data (e.g. name, gender, age and crash location)
are recorde d. Ho wever, other parties, such as
l aw enforcement could combine the EDR data
with the type of personally identifying data rou-
tinely acquired during a crash investigation.
Access to the vehicle and/or the EDR is needed
to read data that is recorded by an EDR, and
special equipment is required. In addition to the
vehicle manufacturer, other parties that have
the special equipment, such as law enforce-
ment, can read the information by accessing the
vehicle or the EDR.
EDR data may be used in civil and criminal mat-
ters as a tool in accident reconstruction, acci-
dent claims and vehicle safety. Since the Crash
Data Retrieval CDR tool that is used to extract
data from the EDR is commercially available,
Mercedes-Benz USA, LLC ("MBUSA") expressly
disclaims any and all liability arising from the
extraction of this information by unauthorized
Mercedes-Benz personnel.
MBUSA will not share EDR data with others
without the consent of the vehicle owners or, if
the vehicle is leased, without the consent of the
lessee. Exceptions to this representation
include responses to subpoenas by law enforce-
ment; by federal, state or local government; in
connection with or arising out of litigation involv-
ing MBUSA or its subsid iaries and affiliates; or,
a s required by law.
Warning: The EDR is a component of the
Restraint System Module. Tampering with, alter-
ing, modifying or removing the EDR component

Introduction

Side impact air bags
G WARNING
Unsuitable seat covers can obstruct or pre-
vent deployment of the air bags integrated
into the seats. Consequently, the air bags
cannot protect vehicle occupants as they are
designed to do. In addition, the operation of
the occupant classification system (OCS)
could be adversely affected. This poses an
increased risk of injury or even fatal injury.
You should only use seat covers that have
been approved for the respective seat by
Mercedes-Benz.
Front side impact air bags C and rear side
impact air bags D deploy next to the outer bol-
ster of the seat backrest.
When deployed, the side impact air bag offers
additional thorax protection. It also offers addi-
tional pelvis protection for occupants in the
front seats. However, it does not protect the: R
head R
neck R
arms
In the event of a side impact, the side impact air
bag is deployed on the side on which the impact
occurs.
The side impact air bag on the front-passenger
side deploys under the following conditions: R
the OCS system detects that the front-
passenger seat is occupied or R
the belt tongue is engaged in the belt buckle
of the front-passenger seat
If the belt tongue is engaged in the belt buckle,
the side impact air bag on the front-passenger
side deploys if an appropriate accident situation
occurs. In this case, deployment is independent of whether the front-passenger seat is occupied
or not.
Window curtain air bags
Window curtain air bags C are integrated into
the side of the roof frame and deployed in the
area from the A-pillar to the C-pillar.
When deployed, the window curtain air bag
enhances the level of protection for the head.
However, it does not protect the chest or arms.
In the event of a side impact, the window curtain
air bag is deployed on the side on which the
impact occurs.
If the system determines that they can offer
additional protection to that provided by the
seat belt, a window curtain air bag may be
deployed in other accident situations
( Y
page 55).
Cushion air bags
i Observe the "Important safety notes" sec-
tion ( Y
page 48).
The rear reclining seat is equipped with a cush-
ion air bag. If the seat backrest is reclined, the
cushion air bag can provide additional occupant
protection in the event of frontal collision situa-
tions. When triggered, the cushion air bag
deploys under the seat cushion. This helps pre-
vent the occupant from slipping off the seat
cushion.
G WARNING
If a child restraint system is installed and the
seat backrest is reclined too far backwards,
the cushion air bag may deploy by mistake in
the event of an accident. There is an increased
risk of injury.50
