G
WARNING
All work on the vehicle and, in particular, work
relevant to safety or on safety-related sys-
tems must be carried out at a qualified spe-
cialist workshop. G
WARNING
Some safety systems only function when the
engine is running. You should therefore never
switch off the engine when driving. Otherwise,
the safety systems of your vehicle may not
function correctly and as a result will no lon-
ger protect you and other persons as inten-
ded. In addition, there is a risk that you may
lose control of your vehicle and thus cause an
accident. G
WARNING
Work carried out incorrectly, or alterations
made to the vehicle, e.g. re-routing of cables
under coverings, could cause the safety sys-
tems of your vehicle to stop working properly.
The safety systems would thus no longer pro-
tect you and other persons as intended. In
addition, there is a risk that you may lose con-
trol of your vehicle and thus cause an acci-
dent.
All work and alterations to the vehicle, e.g.
installations or modifications, should there- 22
Introduction

fore be carried out at
aqualified specialist
workshop. G
WARNING
If work on electronic equipment and its soft-
ware is carried out incorrectly, this equipment
could stop working .The electronic systems
are networked via interfaces. Tampering with
these electronic systems could cause mal-
functions in systems which have not been
modified. Malfunctions such as these can
seriously jeopardise the vehicle's operating
safety and therefore your own safety.
You should therefore have all work and mod-
ifications to electronic components carried
out at a qualified specialist workshop. Declarations of conformity
Wireless vehicle components The following information applies to all com-
ponents of the vehicle and the COMAND sys-
tem which receive and/or transmit radio
waves:
The components of this vehicle which receive
and/or transmit radio waves are compliant
with the basic requirements and other rele-
vant provisions of Directive 1999/5/EC. You
can obtain further information from any
Mercedes-Benz Service Centre.

G
WARNING
If you connect equipment to a diagnostics
connection, it can affect the operation of the
vehicle systems. This could compromise the operating safety of your vehicle while driving.
There is a risk of an accident.
Do not connect any equipment to a diagnos-
tics connection.
G
WARNING
Loose equipment or cables hanging from a
device which are connected to a diagnostic
connection could impede pedal clearance.
The equipment or cables could get caught
between the pedals when driving and braking
suddenly. This could impair the function of the
pedals. There is a risk of accident.
Do not attach any equipment or cables in the
driver's footwell.
! If the engine is switched off and equip-
ment on the diagnostics connection is
used, the starter battery may discharge.
The diagnostics connection is only intended
for the connection of diagnostic equipment at
a qualified specialist workshop.
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
Aq ualified 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
relevan tto safety.

WARNING
If service work is not carried out correctly, the
operating safety of your vehicle may be affec-
ted. This could cause you to lose control of
your vehicle and cause an accident. More-
over, the safety system smay no longer be
able to protect you or others as they are
designed to do.
Always have service work carried out at a
qualified specialist workshop. G
WARNING
Modifications to or work performed incor-
rectly on the following parts can result in the
restraint systems no tfunctioning as intended:
R the restraint system, consisting of seat
belts and their anchorage points, belt ten-
sioners, belt force limiters and airbags
R the wiring
R networked electronic systems
Airbags and belt tensioners could fail to
deploy or be triggered in an acciden tdespite
the deceleration force being sufficien tto trig-
ger the systems, or could be triggered unin-
tentionally. For this reason, never make any
modifications to the restraint systems.
Therefore, you must not tamper with elec-
tronic components or their software.
The seat belts, together with SRS (Supple-
mental Restraint System), are complemen-
tary, co-ordinated restraint systems
(Y page 41). They reduce the risk of injury
in specific, pre-defined types of accident sit-
uations and thereby increase occupant
safety. However, seat belts and airbags gen-
erally do not protect against objects pene-
trating the vehicle from the outside. 40

Driver's kneebag
Driver's kneebag
:deploys under the steer-
ing column .Itis deployed together with the
front airbags. The driver's kneebag is
designed to operate together with the front
airbags in frontal impacts if certain thresholds
are exceeded. The driver's kneebag operates
best in conjunction with correctly positioned
and fastened seat belts.
The driver's kneebag increases protection of
the driver against:
R knee injuries
R thigh injuries
R lower leg injuries
i The driver's kneebag is only available in
certain countries.
Sidebags G
WARNING
If you wish to use seat covers, Mercedes-Benz
recommends that, for safety reasons, you
only use seat covers that have been approved
for Mercedes-Benz vehicles.
The seat covers must have a special tear seam
for sidebags/pelvisbags. Otherwise, the side-
bag/pelvisbag cannot deploy correctly and
would fail to provide the intended protection
in the event of an accident. Appropriate seat
covers can be obtained, for example, from a
Mercedes-Benz Service Centre. Sidebags (example: Coupé)
Front sidebags
:and rear sidebags ;
deploy next to the outer seat cushions.
When deployed, the sidebags offer additional
protection for the thorax of the vehicle occu-
pants on the side of the vehicle on which the
impact occurs. However, they do not protect
the:
R head
R neck
R arms
The sidebags are deployed:
R on the side on which an impact occurs
R at the start of an accident with a high rate
of lateral vehicle deceleration or accelera-
tion, e.g. in a side impact
R independently of the use of the seat belt
R independently of the front airbags
R independently of the belt tensioners
Cabriolet: if the vehicle overturns, the side-
bags are generally not deployed. Sidebags
are deployed if the system detects high vehi-
cle deceleration or acceleration in a lateral
direction and determines that sidebag
deployment can offer additional protection to
that provided by the seat belt. Occupant safety

Headbags
Example
:headbag on the front-passenger side
Headbags are available in the Cabriolet.
Headbags enhance the level of protection for
the head, but not chest or arms, of the vehicle
occupants on the side of the vehicle on which
the impact occurs.
Headbags :deploy in the area of the side
windows at the front. They are deployed:
R at the start of an accident with a high rate
of lateral vehicle deceleration or accelera-
tion, e.g. in a side impact
R on the side on which an impact occurs
R on the driver's and the front passenger's
side if the vehicle overturns and the system
determines that windowbag deployment
can offer additional protection to that pro-
vided by the seat belt
R independently of the use of the seat belt
R regardless of whether the front-passenger
seat is occupied
R independently of the fron tairbags
Pelvisbags G

If you wish to use seat covers, Mercedes-Benz
recommends that, for safety reasons, you
only use seat covers that have been approved
for Mercedes-Ben zvehicles.
The seat covers must have a special tear seam

Windowbags
Windowbags are available in the Coupé
Windowbags :enhance the level of protec-
tion for the head, but not chest or arms, of the

The windowbags are integrated into the side
of the roof frame and deploy in the area
extending from the front door (A-pillar) to the
rear sidewall (C-pillar).
Windowbags are deployed:
R at the start of an accident with a high rate

G
DANGER
If the roll bar is malfunctioning, the AMal‐function Consult workshop message
appears in the multifunction display. The roll
bars will the npossibly not be extended in the
event of an accident .This could result in
severe or even fatal injuries to you and other
occupants. In this case, visit a qualified spe-
cialist workshop immediately and have the
roll bar checked. G
WARNING
Ensure that the area around the roll bars/rear
head restraints is kept clear. Otherwise,
someone could be injured by the roll bars
when they are triggered.
The roll bars are under the rear head
restraints. They are extended if systems
detect that the vehicle is in danger of over-
turning.
When the roll bars are extended, the rear
head restraints also extend automatically.
Once the roll bars are extended, you can no
longer lower the rear head restraints. The soft
top can no longer be closed. In this case, visit
the nearest qualified specialist workshop. NECK-PRO head restraints
Important safety notes G
WARNING
Only use head restraint covers which have
been tested and approved by Mercedes-Benz
for your vehicle model.
The use of non-approved head restraint cov-
ers may prevent NECK-PRO head restraints
from triggering properly. Consequently, the
NECK-PRO head restraints cannot provide the
intended level of protection.
Consult a Mercedes-Benz Service Centre
regarding availability.
The NECK-PRO head restraints reduce the
likelihood 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 colli-
sion 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 (Y page 48). Other-
wise, the additional protection will not be
available in the event of another rear-end col- Occupant safety

swhen dispos-
ing of belt tensioners. Any Mercedes-Benz
Service Centre can provide details of these
regulations.
! If the front-passenger seat is not occu-
pied, do not engage the seat belt tongue in
the buckle on the front-passenger seat.
Otherwise, the belt tensioner could be trig-
gered in the event of an accident.
The seat belts are fitted with belt tensioners.
The belt tensioners tighten the seat belts in
an accident, pulling them close against the
body.
Belt tensioners do not correct incorrect seat
positions or incorrectly fastened seat belts.
Belt tensioners do not pull vehicle occupants
back towards the backrest.
If the seat belt is also fitted with a belt force
limiter and this is triggered, the force exerted
by the seat belt on the vehicle occupant is
reduced.
The belt force limiters for the front seats are
synchronised with the front airbags, which
take on a part of the deceleration force. This
results in the force exerted on the occupant
being distributed over a greater area.
The belt tensioners can only be activated
when:
R the ignition is switched on.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 41).
R the belt tongue is engaged in the buckle on
each of the three-point seat belts in front.
R
The belt tensioners on the seats in the rear
compartmenta re triggered independently of
the lock status of the seat belts.
The beltt ensioners are triggered depending
on the type and severity of an accident:
R if, in the event of a head-on or rear-end col-
lision the vehicle decelerates or acceler- ates rapidly in a longitudinal direction dur-
ing the initial stages of the impact
R if, in the event of a side impact, on the side
opposite the impact the vehicle deceler-
ates or accelerates rapidly in a lateral direc-
tion
R Cabriolet: in certain situations if the vehicle
overturns and the system determines that
it can provide additional protection.
If the airbags are deployed, you will hear a
bang, and a small amount of powder may also
be released. Only in rare cases will the bang
affect your hearing. The powder that is
released generally does not constitute a
health hazard. The 6SRS warning lamp
lights up.
Automatic comfort-fit feature The fron
tseat belts have an automatic com-
fort-fit feature. The automatic comfort-fit fea-
ture reduces the retraction force of the seat
belts. This results in increased seat belt com-
fort. Children in the vehicle
Child restraint systems
Important safety notes G
WARNING
To reduce the risk of serious or even fatal
injury to the child in the event of a sudden
change in direction, braking or an accident:
R children less than 1.50 m tall and under
twelve years of age must always be secured
in special child restraint systems on a suit-
able vehicle seat. This is necessary
because the seat belts are not designed for
children.
R Do not drive with a child secured in a rear-
ward-facing child restraint system on the
front-passenger seat. Exception: if the vehi-
cle is equipped with automatic child seat
recognition on the front-passenger seat Children in the vehicle
53Safety
Z

and the child is secured in a child restraint
system with transponders for automatic
child seat recognition
R if you secure a forward-facing child
restraint system to the front-passenger
seat, you must move the front-passenger
seat as far back as possible.
R childre nmust never travel sitting on the lap
of another occupant. Due to the forces
which occur in the event of a sudden
change of direction, heav ybraking or an
accident, it would not be possible to
restrai nthe child. The child could be thrown
against parts of the vehicle interior and be
seriously or even fatally injured. G
WARNING
The child restraint system cannot perform its
protective function if it is not correctly fitted
to a suitable vehicle seat. The child cannot be
restrained in the event of an accident, heavy
braking or sudden changes of direction. The
child could be seriously or even fatally injured.
For this reason, when fitting a child restraint
system, observe the manufacturer's installa-
tion instructions and the correct use of the
child restraint system.
Child restraint systems should be fitted to the
rear seats. Children are generally better pro-
tected there.
The entire base of the child restraint system
must always rest on the seat cushion. There-
fore, never place objects, e.g. a cushion,
under the child restraint system.
Only use child restraint systems with the orig-
inal cover designed for them. Only replace
damaged covers with genuine Mercedes-Benz
covers.
We recommend the use of child restraint sys-
tems which have been approved for
Mercedes-Ben zvehicles. G
WARNING
Do not leave children unsupervised in the
vehicle, even if they are secured in a child
restraint system. They could injure them- selves on parts of the vehicle. They could also
be seriously or even fatally injured by pro-
longed exposure to extreme heat or cold.
Do not expose the child restraint system to
direct sunlight. Parts of the child restraint sys-
tem could heat up and the child could burn
herself/himself on them.
If a child opens a door, the child or other per-
sons could be injured as a result. They could
get out and injure themselves or be injured by
a passing vehicle.
Observe the general notes on the HOLD func-
tion, which can be found under the same key-
word. G
WARNING
Unsecured or incorrectly positioned loads
increase the risk of injury for children and all
other occupants in the event of:
R an accident
R sudden braking
R a sudden change of direction
Do not transport heavy or hard objects in the
vehicle interior unless they are secured. You
will find further information under "Loading
guidelines" in the index.
If a child is travelling in your vehicle, secure
the child using a child restraint system which
is recommended for Mercedes-Benz vehicles.
The child restraint system must be appropri-
ate to the age, weight and size of the child.
Ideally the child restraint system should be
installed on a suitable rear seat. Make sure
that the child is secured for the trip.
Mercedes-Benz recommends that you use
the listed child restraint systems
(Y page 62). You can obtain further infor-
mation about the correct child restraint sys-
tem from any Mercedes-Benz Service Centre.
i It is advisable to use Mercedes-Benz care
products to clean child restraint systems.
You can obtain information about this at
any Mercedes-Benz Service Centre. 54
