the vehicle's high-voltage electrical system
checked by a qualified specialist workshop.
The components of the vehicle's high-voltage
electrical system are marked with yellow warn-
ing stickers. The cables of the vehicle's high-
voltage electrical system are orange in color.
Vehicles with an electric motor generate much
less driving noise than vehicles with internal
combustion engines. As a result, your vehicle
may not be heard by other road users in certain
situations. This can happen, for example, when
you are parking and your vehicle is not seen by
other road users. This requires you to adopt a
particularly anticipatory driving style, as it is
necessary to allow for the possibility that other
road users may behave erratically.
Declarations of conformity
Vehicle components which receive
and/or transmit radio waves
USA: "The wireless devices of this vehicle com-
ply with Part 15 of the FCC Rules. Operation is
subject to the two following two conditions: 1)
These devices may not cause harmful interfer-
ence, and 2) These devices must accept any
interference received, including interference
that may cause undesired operation. Changes
or modifications not expressly approved by the
party responsible for compliance could void the
user’s authority to operate the equipment."
Canada: "The wireless devices of this vehicle
comply with Industry Canada license-exempt
RSS standard(s). Operation is subject to the fol-
lowing two conditions: (1) These devices may
not cause interference, and (2) These devices
must accept any interference, including inter-
ference that may cause undesired operation of
the device."

Data stored in the vehicle
Data storage
A wide range of electronic components in your
vehicle contain data memories.
32Data stored in the vehicle
Introduction

These data can help provide a better under-
standing of the circumstances in which acci-
dents and injuries occur. NOTE: EDR data are
recorded by your vehicle only if a non-trivial
crash situation occurs; no data is recorded by
the EDR under normal driving conditions and no
personal data (e.g. name, gender, age and acci-dent location) are recorded. However, other par-
ties, such as law enforcement could combine
EDR data with the type of personally identifyingdata routinely acquired during a crash investi-
gation.
Access to the vehicle and/or the EDR is needed
to read data that is recorded by the 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 subsidiaries and affiliates; or,
as required by law.
Warning: The EDR is a component of the
Restraint System Module. Tampering with, alter-
ing, modifying or removing the EDR component
may result in a malfunction of the Restraint Sys-
tem Module and other systems.
State laws or regulations regarding EDRs that
conflict with federal regulation are pre-empted.
This means that in the event of such conflict, the federal regulation governs. As of February 2013,
13 states have enacted laws relating to EDRs.Information on copyright

Introduction

Hybrid vehicles
General notes
Hybrid technology combines a fuel efficient
internal combustion engine with a powerful
electric motor.
Important safety notes
Danger of electric shock
GDANGER
The vehicle's high-voltage electrical system is under high voltage. If you modify components
in the vehicle's high-voltage electrical system
or touch damaged components, you may be
electrocuted. The components in the vehi-
cle's high-voltage electrical system may be
damaged in an accident, although the damage
is not visible. There is a risk of fatal injury.
Following an accident, do not touch any high-
voltage components and never modify the
vehicle's high-voltage electrical system. Have
the vehicle towed away after an accident and
the vehicle's high-voltage electrical system
checked by a qualified specialist workshop.
When towing a vehicle after an accident, be sure
to observe the following sections:
RTransporting the vehicle (Ypage 356)
RTowing the vehicle with the rear axle raised
(Ypage 355)
RTowing a vehicle with both axles on the
ground (Ypage 356)
Read the safety instructions on towing and tow-
starting (
Ypage 354).
All components of the hybrid drive system are
marked with yellow warning stickers that warn
you of the danger of high voltage. The cables of
the vehicle's high-voltage electrical system are
orange in color.
The ignition must be switched off when carrying
out general tasks, such as changing bulbs or
checking the coolant level.
Automatic switching off of the hybrid
drive system
If components of the restraint system are acti-
vated during an accident, the hybrid drive sys-
tem is automatically deactivated.
The hybrid drive system is not activated when
the vehicle is started if:
Ran electrical short circuit is detected in the
hybrid drive system
Ran electrical connection in the hybrid drive
system is disconnected
This ensures that you do not come into contact
with high voltage.
Manual switching off of the hybrid drive
system
The hybrid drive system can be deactivated
manually using the high voltage switch-off
device.
!To prevent damage to the hybrid drive sys-
tem please observe the following instruc-
tions:
Ronly deactivate the hybrid drive system
manually in the following situations.
Rwork on the hybrid drive system may only
be carried out at a qualified specialist work-
shop, even when it has been deactivated
manually.
Deactivate the hybrid system manually if:
Rthe 6 restraint system warning lamp in the
instrument cluster lights up after an accident
Rthe vehicle is badly damaged, e.g. after an
accident, and the restraint system compo-
nents were not activated
Rthe vehicle is badly damaged and has to be
towed or transported
