st arting the engine.
i If you depress the brake pedal when starting
the engine, the pedal tra vel is longer than usual

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
must be carried out at a qualified specialist
workshop. Starting the engine

tain poisonous carbon monoxide. Breathing
in exhaust fumes constitu tes a health haz-
ar dand could lead to unconscio usness and
death. 209en_d2.boo Seite

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

60 Safety
Occupant safety
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
ma y als obe ex tended. If a child
istravelling in the vehicle:
! 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

Risk of inju ry Mak
esure that the range of movement of
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

tion has been rectified.
