In situations like this, the body, the under-
carriage, chassis parts, wheels or tires
could be damaged without the damage
being visible. Components damaged in thisway can unexpectedly fail or, in the case of
an accident, no longer withstand the strain
they are designed to.
If the underbody paneling is damaged,
combustible 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 specialist workshop. If on con-
tinuing your journey you notice that driving
safety is impaired, pull over and stop the
vehicle immediately, paying attention to
road and traffic conditions. In such cases,
consult a qualified specialist workshop.
Declarations of conformity
Vehicle components which receive
and/or transmit radio waves
USA: "The wireless devices of this vehicle
comply with Part 15 of the FCC Rules. Oper-
ation is subject to the following two condi-
tions: 1) These devices may not cause harm-
ful interference, and 2) These devices must
accept any interference received, including
interference that may cause undesired oper-
ation. Changes or modifications not expressly approved by the party responsible for com-
pliance 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
following two conditions: (1) These devices
may not cause interference, and (2) These
devices must accept any interference, includ-
ing interference that may cause undesired
operation of the device."
Diagnostics connection
The diagnostics connection is only intended
for the connection of diagnostic equipment at
a qualified specialist workshop.
GWARNING
If you connect equipment to the diagnostics
connection in the vehicle, it may affect the
operation of the vehicle systems. As a result, 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.
GWARNING
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
An authorized Mercedes-Benz Center is a
qualified specialist workshop. It has the nec-
essary specialist knowledge, tools and quali-
fications to correctly carry out the work
required on your vehicle. This is especially the case for work relevant to safety.

NECK-PRO head restraints
Important safety notes
GWARNING
The function of the head restraint may be
impaired if you: R attach objects such as coat hangers to the
head restraints, for example
R use head restraint covers
If you do so, the head restraints cannot fulfill
their intended protective function in the event of an accident. In addition, objects attached
to the head restraints could endanger other
vehicle occupants. There is an increased risk
of injury.
Do not attach any objects to the head
restraints and do not use head restraint cov-
ers.
Method of operation
NECK-PRO head restraints reduce the likeli-
hood of head and chest injuries. The NECK-
PRO head restraints on the driver's and front-
passenger seats are moved forwards and
upwards in the event of a rear-end collision of
a certain severity. This provides better head
support.
If the NECK-PRO head restraints have been
triggered in an accident, you must reset the
NECK-PRO head restraints on the driver’s and
front-passenger seat ( Ypage 56). Other-
wise, the additional protection will not be
available in the event of another rear-end col- lision. You can recognize when NECK-PRO
head restraints have been triggered by the
fact that they have moved forwards and can
no longer be adjusted.
Mercedes-Benz recommends that you have
the NECK-PRO head restraints checked for
functionality at a qualified specialist work-
shop after a rear-end collision.
Resetting triggered NECK-PRO head
restraints
Do not insert your finger between the uphols- tery of the head restraint and the seat. Pay
particular attention while resetting the NECK-PRO head restraints.
X Tilt the top of the NECK-PRO head restraint
cushion forwards in the direction of
arrow :.
X Push the NECK-PRO head restraint cushion
down as far as it will go in the direction of
arrow ;.
X Firmly push the NECK-PRO head restraint
cushion back in the direction of arrow =
until the cushion engages.
X Repeat this procedure for the second
NECK-PRO head restraint.
iResetting the NECK-PRO head restraints
requires a lot of strength. If you have diffi-
culty resetting the NECK-PRO head
restraints, have this work carried out at a
qualified specialist workshop.

dows from traveling upwards during the auto-
matic closing process, the side window opensagain automatically. During the manual clos-
ing process, the side window only opens
again automatically after the corresponding
switch is released. However, the automatic
reversing feature is only an aid and does not
relieve you of the responsibility of paying
attention when closing a side window.
GWARNING
The reversing feature 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.
Make sure that no body parts are in close
proximity during the closing procedure. If
someone becomes trapped, press the switch
to open the side window again.
Opening and closing the side win-
dows in the front
The switches for the front side windows are
located on the driver's door. There is also a
switch for the front-passenger side window
on the front-passenger door.
The switches on the driver's door take prec-
edence.

Problems with the side windows
GWARNING
If you close a side window again immediately after it has been blocked or reset, the side window
closes with increased or maximum force. The reversing feature is then not active. Parts of the
body could be trapped in the closing area in the process. This poses an increased risk of injury oreven fatal injury.
Make sure that no parts of the body are in the closing area. To stop the closing process, releasethe switch or push the switch again to reopen the side window.
ProblemPossible causes/consequences and MSolutions
A side window cannot
be closed because it is
blocked by objects, e.g.
leaves in the windowguide.X Remove the objects.
X Close the side window.
A side window cannot
be closed and you can-
not see the cause.If a side window is obstructed during closing and reopens again slightly:
X Immediately after the window blocks, pull the corresponding
switch again until the side window has closed.
The side window is closed with increased force.
If a side window is obstructed again during closing and reopens
again slightly: X Immediately after the window blocks, pull the corresponding
switch again until the side window has closed.
The side window is closed without the anti-entrapment feature.
Roof
Important safety notes
GWARNING
If you do not fully open/close the soft top, the
soft-top hydraulics depressurize after a short
time. This causes the soft top to lower unex-
pectedly and may cause you or others to be
trapped. There is a risk of injury.
Always open or close the soft top completely.
GWARNING
Closing the roof manually is a complicated
and technically demanding procedure, which
requires a lot of strength. You or others can
become trapped. There is a risk of injury.
Only have the soft top closed manually at a
qualified specialist workshop.
!Never sit on the rear shelf or store heavy
objects there. You will otherwise damage
the roof and the rear shelf of your vehicle.
!Do not forget that the weather can
change abruptly. Make certain that the roof
is closed when you leave the vehicle. The
vehicle electronics can be damaged if
water enters the vehicle interior.
!When opening and closing the roof, make
sure that:
