Introduction
Op erating safety Operating safety
G
Risk of accident Work incorrectl
ycarrie dout on electronic
equipment an dits software could stop this
equipment working. Th eelectronic systems
are networked via int erfaces. Tampering
with these electronics systems could even
ca usema lfunctions in systems that have not
be en modif ied. Such malfunctions co uld
seriously impair the operating safety of your
vehicle, and thus your own safety.
Other work onormod ifications to the vehi-
cl e that have been carried out incorrectly
coul dalso jeopardise operating saf ety.
Som esafety syste ms onlyop era te when the
engine is running. For this reason, do not
switch off the engine while driving. G
Risk of accident Always
have maintenance work carried out
at a qualif ied specialist workshop which has
the necessary specia list knowledge and
tools to carry out the work re quired.
Merce des-Ben zrec ommends that you use a
Merc edes-Benz Service Centre for this pur-
pose.
In particular, work re levant to safety oron
safety-relat edsystems must be carried out
at a qualifie dsp ecialist workshop. G
Risk of accident A heavy impact against the vehicle under-
body, tyres or wheels could damage your
vehicl
eif, for example, the vehicle bottoms
out on rough terrain or is driven over an
ob stacle athig hspee d, for example. This
also applies to vehicles fitted with under-
body protection.
In this ca se,h aveyour ve hiclec hecked at a
qualified specialist workshop which has the
necessary specialist kn owledge and tools to
carry out the work requir ed. Mercedes-Benz
recommends that you use a Mercedes-Be nz
Servi ceCentre for this purpose.

6 Pull up on the shoulder belt to tighten
the belt across your lap if necessary.
!Do no tdepress the accelerator pedal when
st arting the engine.
i If you depress the brake pedal when starting
the engine, the pedal tra vel is longer than usual
and the pedal resistance is lo w.
If you depress the brake pedal after starting the
en gine, the pedal travel and resistance return to
normal. G
Riskof injury You could injure
yours elfin an accident if
you use seat belts which:
! aredamaged
! have been subjected to a loadin an acci-
dent
! have been modified
These seat belts can then nolong er function
or protect as intended.
Do not pass the seat belt strap over sharp
edges .It could tear.
Ma ke sure that th eseat belt isnot caught in
the door or seat adjustmen tmechanism. It
coul dbe damaged. G
Risk of injury Check the seat
belts regularly for damage.
You should never modify the seat belts your-
self. They might not function properly any
more.
Always have seat belts which are damaged
or have been subjected to a load in an
ac cident replaced ata qualifi edspecialist
workshop, which has the necessary special-
is t knowledge and tools to carry out the
required work. Mercede s-Benz recom mends
that you usea Merced es-Benz Service Cen-
tre for this purpose. In particular ,work rele-
vant to safety or on safety-related systems

50 Safety
Occupant safety
Triggering ofbelt tensioners, belt force limiters and
airbags
In the event ofa collision, the sensor in the
airbag contro lunit evaluates important
physical data, such as duration, direction
and rate of veh icle deceleration or acceler-
ation. Based on this evaluation and pre-
emptively, the belt tensioners are the first
to be triggered by the airb agcontrol unit in
a collis ion with longi tudinal deceleration as
a function of the rate of vehicle decelera-
tion.
The front airbags are not triggered unless a
second activation threshold is reached, i.e.
an even higher rate of vehicle deceleration
in the longitudinal direction is exceeded. i
Thefront airbag on the front-passenger side
is only tri ggered if:
! the front-passenger seat oc cupancy sensor
has detected that the seat is occupied
! the PASSENGER AIRBAG OFF warning lamp
onthe centre console is not lit (
=page 64)
The belt tensioners are only activated if the seat
belt buck le tongue is correctl yengaged in the
se at belt buckle.
Criteria for the activation of belt
tensioners and airbags
To determine whether it is necessary to
activ ate a belt tensioner or airbag, the air-
bag control unit evaluates the duration and
direction of vehicle deceleration or accel-
eration during the initial phase of the colli-
sion.
The activation thresholds for the belt ten-
sioners and the airbags are variable and
are adapted in accordance with the rate of
ve hicle deceleration. This process ispre-
emptive in nature as airbag deployment
must take place during the impact and not
at the end of the collision. G
Risk of inju ry A malfu
nction has occurred if the 1
warning lamp:
! doesnot com eon when yousw itchon
th eignition
! does not go out after a few seconds
when the engine is running
! comes on again
Individ ual systems could beactivated inad-
verte ntly or may not be triggered at all in the
event of an accident with a high rate of vehi-
cle deceleration. Ifthis happens, have the
SRS system checked and repaired immedi-
ately at a qualified specialist wor kshop
wh ich has the necessary specialist know-
ledg eand tools to carry out the work
require d.
Mercedes-Benz recomme nds that youuse a
Mercedes-Benz Service Centre for this pur-
pose. In particular, work relevant to safety
or on safety-re lated systems must be car-
ried out at a qualified specialist workshop. 209en_d2.boo Seite

Risk ofinjury If the belt tensi
onersha ve bee ntriggered,
have them replaced ata qualified specialist
workshop which has th eneces sary special-
ist knowledge and tools to carry out the
work required. Mercedes -Benz recommends
that you use a Mercedes-Be nzService

Ob serve the safety regulations for th edis-
posal of belt tensioners. Any Mercedes-B enz
Service Centre can provide detail sof these
regulations. G
Risk of injury To reduce the risk of serious or fata
linjury in
an accident with a high rate of deceleration,
e.g. injuries caused by an airbaginflating
within milliseconds or in the ev ent of abrupt
br aking, please observe the following
inst ructions:
! Allve hicle occupants must select a seat
position in which it is possible to wear
the seat belt correctl ybut which is as far
back from the airba gas possible. The
position of the driver's seat must allow
the driver to drive th evehicle safely. The
driver's arms shou ldbe slightly bent
when holding the steering wheel. The
distance from th edriver's seat to the
pedals must be such that the dr iver can
fully depress the pedals.
! Vehicle occupants should wear their
seat belt correctly at all times and lean
back against the bac krest, which should
be positioned almost vertically. The
head restraint should support the back
of yo urhead at abo uteye level. !
Move the front- passenger seat as far to
the rear as possible, especially if a child
is secured in a restraint system installed
on this sea t.
! Never secure a rearward-facing child
restraint system on the front-pass enger
seat if the front-passenger front airbag
is not deactivate d.In the CLK-Class, the
fr ont-passen ger fro ntairbag is deacti-
vated if a child restraint system with
automatic child seat recognition is
secured to a front-passenger seat and
the AIRBAG OFF lamp is lit. If the auto-
matic child seat rec ognition is defective,
children must be secured in a child
restraint system ins talled on a suitable
re ar seat. If you are using aforward-f ac-
in g child seat on the fro nt-pa ssen ger
seat, the front-passenger seat must be
moved as far to the rear as possibl e. 209en_d2.boo Seite

The roll-over bars are deployed automati-
cally if it is detected that there is a risk of
the vehicle overturning.
The roll-over bars are located below the
rear head restrain ts. You may ret ract the
extended roll-o ver bars manually when the
soft top is open ( =page 344).
i You cannot lower the rear head restrai nts if
the roll-over bars are deplo yed.
If the roll-over bars deplo yau tomatically, you will
hear a ra ttling noise and the rear head restraints

! secure the child us ing a child restraint
system which is appropriate to its age
and size and which has been approved
for Mercedes-Be nz, preferably on a
suitable rear seat
! make sure thatthe child is secured
throughout the trip
You can obtain child seats and informat ion
about the correct child restraint system
from any Mercedes-Benz Service Centre. Roll-over

the roll-over bars is not obstructed, other-
wise persons could be injured when the roll-
over bars are extended.
For this reason, always pu ll the rear seat
head restraints out to the st opif passengers
are travelling in the rear. G
Risk of injury If the
\ warning lamp inthe rev counter
remains lit for a long time after the engine
has been started, th ere is a fault.
The roll-over bars will then fail to deploy
automatically in the event ofan accident
even if the systemdetects that there is a
danger of the vehic leov erturning. Thi scould
result in serious or fata lin ju ry to yourself or
ot her vehicle occupan ts.For safety reasons,
therefore, alwa ysdrive with the roll-over

se nger side remain active even if the front -pas-
senger airb agis deactivat ed. ISOFIX
child seat secur ing system*
ISOFIX is a standardised securing system
for speci alchild seats in the rear. The
securing rings provided for two child seats
are located on the left andright-hand sid es
of the rear seats bet ween the seat cush-
ions and the ba ckrest. G
Risk ofinjury If the front-passenger front airbag warning
lamp does not light up when the child seat is
fitted, the front-passenger front airbag has
not been de
activated. The child could suffer
life-t hreatening injuries if the front-passen-
ger front airbag deploys. If the above warn-
ing lamp does not light up when the child
seat is fitted, proceed as follows:
! Do no tuse a rearward-facing child seat
on the fr ont-pass engerse at.
P68.10-3078-31 !
Fit the rearward-facing child seat on a
suitable rear seat.
or
! Use a forward-facing child seat onthe
fr ont-passen gers eat. In this case, you
must move the front-passenger seat to
its rearm ostp osition.
! Have the automatic child seat recogni-
tion checked at a qualified specialist
workshop which has th eneces sary spe-
cialist knowledge and tools to carry out
the work required. Merc edes-Benz rec-
om mends that you use a Mer cedes-
Benz Service Centre for this purpose.
In particular, work re levant to safety oron
safety-relat edsystems must be carried out
at a qualifie dsp ecialist workshop. G
Risk of inju ry A child restraint system secured by the
ISOFIX child seat securing system does not
pro
vide sufficient protection for children
weighing more than 22 kg. For this reason,
do not secure childre nweighing more than
22 kg in a chi ldrestra int system securedby
the ISOFIX child seat sec uring syste m.If the
child weighs more than 22 kg, you should
secure the child restraint system using a
lap-shoulder sea tbelt. 209en_d2.boo Seite
