warning stickers. The cables of the vehicle's
high-voltage electrical system are orange.
Vehicles with an electric motor generate sig-
nificantly less noise than vehicles with inter-
nal combustion engines. As a result, in certain situations your vehicle may not be heard by
other road users. This can happen, for exam-
ple, 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 pos-
sibility that other road users may behave
unpredictably. Declarations of conformity
Wireless vehicle components The following information applies to all com-
ponents of the vehicle and the information
systems and communication devices integra-
ted into the vehicle which receive and/or
transmit radio waves:
The components of this vehicle that receive
and/or transmit radio waves are compliant
with the basic requirements and all other rel- evant conditions of Directive 1999/5/E C.
You can obtain further information from any
Mercedes-Benz Service Centre.
Electromagnetic compatibility The electromagnetic compatibility of the vehi-
cle components has been checked and certi-fied according to the currently valid version of
Regulation ECE-R 10. Diagnostics connection
The diagnostics connection is only intended
for the connection of diagnostic equipment at a qualified specialist workshop. G
WARNING
If you connect equipment to a diagnostics
connection in the vehicle, it can affect the
operation of the vehicle systems. This may affect the operating safety of the vehicle.
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 may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor-mats 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
A qualified specialist workshop has the nec-
essary special skills, tools and qualifications
to correctly carry out any necessary work on
your vehicle. This particularly applies to work
relevant to safety.
Observe the notes in the Service Booklet.
Always have the following work carried out at a qualified specialist workshop:
R work relevant to safety
R service and maintenance work
R repair work
R modifications, installations and conver-
sions Introduction

Important safety notes
G
WARNING
While opening the side windows, body parts
could become trapped between the side win- dow and the door frame as the side window
moves. There is a risk of injury.
Make sure that nobody touches the side win-
dow during the opening procedure. If some-
body becomes trapped, release the switch or pull the switch to close the side window again. G
WARNING
While closing the side windows, body parts in the closing area could become trapped. There is a risk of injury.
When closing make sure that no parts of the
body are in the closing area. If somebody
becomes trapped, release the switch or press
the switch to open the side window again. G
WARNING
If children operate the side windows they
could become trapped, particularly if they are left unsupervised. There is a risk of injury.
Activate the override feature for the rear side
windows. When leaving the vehicle, always
take the key with you and lock the vehicle.
Never leave children unattended in the vehi-
cle. Side window reversing feature
The side windows are equipped with an auto-
matic reversing feature. If a solid object
blocks or restricts a side window from trav-
elling upwards during the automatic closing
process, the side window opens again auto-
matically. During the manual closing process, the side window only opens again automati-
cally after the corresponding switch is
released. The automatic reversing feature is
only an aid and is no substitute for your atten-
tion when closing a side window. G
WARNING
The reversing function does not react:
R to soft, light and thin objects, e.g. small fin-
gers
R while resetting
This means that the reversing feature cannot
prevent someone being trapped in these sit-
uations. There is a risk of injury.
When closing, make sure that no parts of the
body are in the closing area. If someone
becomes trapped, press the switch to open
the side window again. Opening and closing the side win-
dows
The switches for all side windows are located
on the driver's door. There is also a switch on
each door for the corresponding side window.
