the operating safety of the vehicle could be
affected. There is a risk of an accident.
Do not connect any equipment to a diagnos-
tics connection in the vehicle. 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 equip-
ment on the diagnostics connection is
used, the starter battery may discharge.
Connecting equipment to the diagnostics
connection can lead to emissions monitoring information being reset, for example. This
may lead to the vehicle failing to meet the
requirements of the next emissions test dur-
ing the main inspection. Qualified specialist workshop

Federal Regulations, Part 575 pursuant to the "National Traffic and Motor Vehicle Safety Actof 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 notify-
ing Mercedes-Benz USA, LLC.
If NHTSA receives similar complaints, it may
open an investigation, and if it finds that a

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:

! Follow the instructions in this manual

Data recording
This vehicle is capable of recording diagnostic information relating to vehicle operation, mal-functions, and user settings. This may include information about the performance or status
of various systems, including but not limited
to, engine, throttle, steering or brake sys-
tems, that is stored and can be read out with
suitable devices, particularly when the vehi-
cle is serviced. The data obtained is used to
properly diagnose and service your vehicle or to further optimize and develop vehicle func-
tions. COMAND/mbrace (Canada: TELEAID)
If the vehicle is equipped with COMAND or
mbrace, additional data about the vehicle’s
operation, the use of the vehicle in certain
situations, and the location of the vehicle may be compiled through COMAND or the mbrace
system.
For additional information please refer to the COMAND User Manual and/or the mbrace
Terms and Conditions. Event data recorders
This vehicle is equipped with an event data
recorder (EDR). The main purpose of an EDR
is to record data that will assist in under-
standing how a vehicle’s systems performed
in certain crash or near crash-like situations,
such as during air bag deployment or when
hitting a road obstacle. 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 are
operating
R whether or not the driver and passenger
seat belts are fastened
R how far (if at all) the driver is depressing the
accelerator and/or brake pedal and
R how fast the vehicle is traveling
This data can help provide a better under-
standing of the circumstances in which 30
Introduction

crashes and injuries occur. NOTE: EDR data is
recorded by your vehicle only if a non-trivial
crash situation occurs; no data is recorded by the EDR under normal driving conditions andno personal data (e.g., name, gender, age,
and crash location) are recorded. However,
other parties, such as law enforcement, can
combine the EDR data with the type of per-
sonal identification data routinely acquired
during a crash investigation.
Access to the vehicle and/or the EDR is nee-
ded 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 enforcement, can read the information by
accessing the vehicle or the EDR.
EDR data may be used in civil and criminal
matters as a tool in accident reconstruction,
accident 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 lia- bility arising from the extraction of this infor-
mation by unauthorized Mercedes-Benz per-
sonnel.
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
enforcement; by federal, state or local gov-
ernment; in connection with or arising out of
litigation involving MBUSA or its subsidiaries
and affiliates; or, as required by law.
Warning: The EDR is a component of the Sup-
plemental Restraint System ("SRS") Module.
Tampering with, altering, modifying or remov- ing the EDR component may result in a mal-
function of the SRS Module and other sys-
tems.
State laws or regulations regarding EDRs that
conflict with federal regulation are pre-emp-
ted. This means that in the event of such con- flict, the federal regulation governs. As of February 2013, 13 states have enacted laws
relating to EDRs. Information on copyright
