Adjusting
You can adjust your seats either manually
or electrically*, depending on your vehi-
cle's equipment. Ad
just ing Seats
G
Risk of accident Only adjust the driver's
seat when the vehi-
cle is stationary. Oth erwise, you may no
lon ger be able toobserve road and traffic
cond itions and you could lose control of the
ve hicle as a result ofthe seat movin g. G
Risk of accident and injury Make sure that nobody can become trapped
as
you adjus tthe seat.
To reduce the risk of seri ousor fatal inju ries
in the event of an acci dent or heavydeceler-
ation, e.g .by an airbag inflating within milli-
seconds, observe the following points:
! All occupants must selec ta se at
position that allows the seat belt to be
worn correctly and th at is asfaraw ay
fr om the fro ntairbags as possible.
The position of the driver's seat must
allow the driver to drive the vehicle
sa fely. The distanc efrom the driver's
seat to th epedals mu st be such tha tthe
driver can fully depress the pedals. The
distance between the driver's chest and
the centre of the airbag cover must be
more than 25cm. The dri ver's ar ms
should beslightly bent when holding the
steering wheel. !
Position the front-pa ssen gerse at as far
ba ck as possible, especially if a child is
sitting on this seat or if a child is secured
in a restraint system onthis seat.
! Occ upants must always wea rthe irseat
be ltco rrec tly and po sitio ntheir back-
rest as clo seto the vertical as possible.
The head restraint should support the
ba ck ofyour head at about eye level.
! Rearward-faci ngchild restraint systems
must not be fitted to th efront-passen-
ger seat unless the front passenger air-
bag has been deactivated. In Merc edes-
Benz vehi cles, the front passenger air-
ba g is deactivated and the AIRBAG OFF
warning lamp is lit when a child restraint
system with automatic child seat recog-
nition is fitted to a front-passenger seat
in a vehicl ewith automatic child seat
recognition. 209en_d2.boo Seite

iving G
Risk of accident Do not kee
panyobjects in the driver' sfoo t-
well. Make sure that floormats or car pets in
the driver's footwell:
! donot obstruct the pedals
! areproperl ysecured
The objects could otherwise get caught
between the pedal sif you accelerate or
brake suddenly. You would then not be able
to brake or accelerate. This coul dlead to
ac cident and injury. Wearing seat belts
G
Risk of injury A seat belt that is not worn correctl
y,or that
is not correctly engaged in the seat belt
buckle, cannot perform its intende dprotec-
tive function. It could even cause severe or
fatal injuries.
For this reason, make sure that all the occu-
pants – in particular, pregnant women –
always wear their seat belts correctly.
! The se atbelt must not be twisted and
must pass closely over your body. You
should therefore avoid wearing bulky
clot hing (e.g. winter coats). The shoul-
der section of the belt must be routed
over the middle of your shoulder – never
ar ound you rnec kor under your arm –
and must be pulled tight against the
upper body. The lap bel t must crossover
your lap as low down as possibl eat all
times, i.e. over your hip joints – not
across your stomach or lower abdom en.
If necessary, press the belt strap down a
bit and retighten bypulling the seat belt
upwards towards the belt reel. !
Do not route the belt strap over sharp or
fragile objects, especially if these are on
or inside your clothing, e.g. spectacles,
pens or keys. The belt strap could ot her-
wise be damaged and you could be
injured as a result.
! Only one person shou ld use each seat
belt at any one time. Do not allow chil-
dren to be carried on the lap of another
occupant since the child will then no
longer be secured in the event of an
accident, braking or a sudden change in
direction. This could result in severe or
fatal injuries to the child or other occu-
pants.
! Persons less than 1.50 m tall cannot
wear the seat belts correctly. Persons
less that 1.50 m tall therefore require
suitable restraint systems. 209en_d2.boo Seite

Getting started
Driving
The < seat belt warni ng lamp in the
instrument cluster reminds you to ensure
that all occupants are wearing their seat
belts.
If the driver has not fastened his seat belt,
the < seat belt warning lamp lights up
if the doors are closed and the engine is
running. In addition, an intermitten tsignal
sounds from a speed of 25 km /hupwards.
The intermittent signal ceases:
! as soon as the driver has fastened his
seat belt
! after a maximum of 93 seconds
! when the vehicle is stationary
The < seat belt warning lamp only goes
out once the driver has fastened his seat
belt. !
Children less than 1.50 m tall and
yo un ger than 12 years ofage cannot
wear the seat belts properly. Always
secure these children in suitable child
re straint systems on seats designe dfor
this purpose ( =pag e62). Please follow
the manufacturer's installation instruc-
tions when installing child restraint sys-
tems.
! Do not secure any objects with a seat
belt if it is also being used by one of the
vehicle 'soccupan ts. G
Risk ofinjury The seat belt only prov
ides its intended
degree of protection if the seat backrest is
positioned as close to the vertical as possi-
ble, allowing th eoccupant to sit upright.
Avoid sea tpositions which do not allow the
seat belt to be routed correctly ( =
pag e25).
Therefore, po sition the bac kres ts as close to
the vertical as possible. Never drive with the
backrest inclined too far backwards. G
Risk of injury Airbags are de
signed not to be triggered in
al lac cident situations, since aco rrectly fas-
tened seat belt will often besufficient for
providing an effective degree of protection.
Airbags are not a substitute for seat belts.
To reduce the risk of severe or eve nfatal
in jury, make sure that all occupants – in par-
ticular, pregnant women – always wear their
seat be lts correctly, are seated inan upright
positio nand have their seats positio ned
almost vertic ally ( =

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

The purpose of head/thorax airbag deploy-
ment is to enhance the protection for the
he ad and chest (but not the arms)of the
ve hicle occupants on the side of the vehi-
cle on whi chthe impact occurs. The head /
thorax airbags are fitte din the outer sides
of the front seat backrests and in the side-
wall in the rear. Th
e hea d/thor ax airbags are trigger ed:
! inthe first stages of an accident with
high lateral forces of vehicle decelera-
tion or acceleration
! on the side on which an impact occurs
! ifthe system foresees that airbag
deployment can offer additional pro-
tection to that provided by the seat belt
! ifthe seat belt is fas tened
! independently of the front airbags
The front-passenger head /thorax airbag
wi ll only be triggered ifthe front-passenger
seat has objects placed onit or if it is actu-
ally occupied.
On vehicles with automatic child seat rec-
ognition on the front-passenger seat, the
front-passenger head /tho rax airbag will
only be triggered if the PASSENGER
AIRBAG OFF warning lamp on the centre
console is lit, i.e. a child seat with auto-
matic child seat recognition transponder
is installed on th isseat. In an accident, the head
/thorax airbag
inflates in the area of the front side win-
dow.

Mercedes-Benz recommends that you only
use the child restraint systems listed
on ( =page 63). G
Riskof injury Do not leave children unsupervi
sedin the
vehicle, eve nif the yare secured in a child
restra int system. The children could:
! injure themselv es on parts of the vehicle
! press the central locking switch, thereby
releasing the child-pr ooflo ck s, and then
open the doors. This could result in
injury to themselves and other persons.
Or they could get out of the vehicle,
injuring themselves as they do so or
they could be injured by passing vehi-
cl es
! beser iously or even fatally harmed by
prolonged exposure to heat G
Risk of injury To reduce the risk of serio
us orfatal inj uryto
the child in the event of an accident, braking
or a sudden cha nge in direction:
! Always secure children less than 1.50 m
tall and under twelve years of age in spe-
cial child restraint systems installed on
a suitable vehicle seat, since they can-
not wear the seat belts correctly
! Do not secure children unde rtwelve
years ofage on the fro nt-passenger seat
unless the child is secured in a child
restraint system equipped wit hauto-
matic child seat rec ognition
! Onnoaccount should children travel sit-
tin gon the lap ofanother occupa nt. It
would not be possible torestrain the
children as a result of the forces acting
in the event of an accident, sudden
braking or abru ptchanges in direction.
They would be thrown ag ainst parts of
the vehic leinterior and be seriously or
fatally injured
! All vehic leoc cupants must wear their
seat belt correctly at all times G
Risk of inju ry If the child restraint system has not
been fit-
ted correctly to a suitable vehicle seat, the
child cannot be restrained in the event of an
accident or sudden braking and could there-
fore be seriously or fatally injured.
For this reason, observe the installation
instructions issued by the child restraint
syst em manufactu rer when fitting the child
restraint system.
It is preferable to fit the child restraint sys-
tem to the rear seats. The child is generally
better protected there.
For this reason, donot place objects (e.g. a
cushion) underneath the child restraint sys-
tem. The entir ebase of the child restraint
system must be in contact with the seat sur-
fa ce at all times. 209en_d2.boo Seite

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
