belt MERCEDES-BENZ G-CLASS SUV 2012 User Guide

R
Only one person should use each seat belt
at any one time. Children must never travel
sitting on the lap of another occupant. The
child will not be secured in the event of an
accident, heavy braking or sudden change
of direction. This may result in the child or
other occupants being seriously or fatally
injured.
R Persons under 1.50 mtall cannot wear the
seat belts correctly. For this reason secure
persons less than 1.50 m tall in specially
designed, suitable restraint systems.
R Children unde r1.50 mtall and younger
than twelve years of age canno twear the
seat belts correctly. For this reason secure
them in special suitable child restraint sys-
tems installed on a suitable seat. Additional
information can be found in the Operating
Instructions in the chapter "Safety", "Chil-
dren in the Vehicle". Observe the installa-
tion instructions of the child restraint sys-
tem manufacturer.
R Do not secure an object with a seat belt if
the seat belt is also being used by one of
the vehicle's occupants. G
WARNING
The seat belt does not offer the intended level
of protection unless the backrest is almost
vertical. Under certain circumstances, this
could cause severe or even fatal injuries in the
event of an accident.
Before starting a journey, make sure that the
seat is properly adjusted and that the back-
rest is almost vertical. G
WARNING
Ad irty or damaged seat belt or one that has
been modified or subjected to a load in an
accident no longer offers the intended level of
protection. Under certain circumstances, this
could cause severe or even fatal injuries in the
event of an accident.
For this reason, chec kregularly that the seat
belts are not damaged or dirty. Always have damaged seat belts or seat belts
that have been subjected to a load in an acci-
dent replaced at a qualified specialist work-
shop.
For safety reasons, Mercedes-Benz recom-
mends that you only use seat belts which have
been approved by Mercedes-Benz for your
vehicle.
Seat belts are the most effective means of
restraining the movement of vehicle occu-
pants in the event of an accident. This
reduces the risk of vehicle occupants coming
into contact with parts of the vehicle interior.

Belt warning for the driver and front
passenger
The
7 seatbelt warning lamp in the instru-
ment cluster is a reminder for all occupants
to fasten their seat belts. It may light up con-
tinuously or flash. In addition, there may be a
warning tone.
The 7 seat belt warning lamp goes out and
the warning tone ceases when the driver and
the fron tpassenger have fastened their seat
belt.
For certain countries only: regardless of
whether the driver and th efront passenger
have fastened their seat belts, the 7seat
beltw arning lamp lights up for six seconds
after the engine is started. It then goes out if
the driver and the fron tpassenger have fas-
tened their seat belts.
i Further information about the 7seat
belt warning lamp (Y page 252).
Rear seat belt status indicator The rear-compartmen
tseat belt status indi-
cator tells you if the rear passengers have
their seat belts fastened.
The rear-compartment seat belt status indi-
cator indicates the rear seat on which the belt
is fastened. The üsymbol in the multi-
function display indicates afastened seat
belt .Ifaseat belt is not fastened or if a seat
is not occupied, the ýsymbol is displayed.
The rear-compartments eat belt status indi-
cator appears in the multifunction display for
around 30 seconds if:
R you drive off and reach a speed of approx-
imately 10 km/h.
R the rear passengers fasten or unfasten
their seat belts while the vehicle is in
motion.
R someone gets in or out of the vehicle and
the vehicle drives off again.
You can also cancel the rear seat belt status
indicator immediately (Y page 228).i
The status indicator for the rear-compart-
ment seat belts is only available for certain
countries.
Belt tensioners, belt force limiters G
WARNING
The belt tensioners in the rear only function if
the belt buckles can be pulled down unob-
structed. They must not be restricted in any
way. Therefore, do not grab the belt buckles
and do not place any objects under the belt
buckles. Otherwise, the tensioning of the belt
by the buckle is restricted or will not function,
and will not provide any additional protection. G
WARNING
If the seat belt tensioners have been trig-
gered, they provide no additional protection
in the event of another accident. Therefore,
have belt tensioners which have been trig-
gered replaced at a qualified specialist work-
shop.
Comply with safety regulations when 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.
X In order to ensure that the pyrotechnic seat
belt tensioners have not been triggered,
always have the seat belts checked after an
accident.
If the belt tensioners have been triggered,
they must be replaced.
The fron tseat belts and the outer seat belts
in the rear are equipped with belt tensioners
and belt force limiters.
The belt tensioners tighten the seat belts in
an accident, pulling them close against the
body. Occupant safety
47Safety Z

Belt tensioners do not correct incorrect seat
positions or incorrectly fastened sea
tbelts.
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 occupan tis
reduced.
The front beltf orce limiters are synchronised
with the front airbags, which take on a part of
the deceleration force. Thus, the force exer-
ted on the occupant is distributed over a
greater area.
The belt tensioners can only be activated if:
R the key is in position 1or 2in the ignition
lock.
R the restraint systems are operational; see
"SRS warning lamp" (Y page 39).
R for each three-point seat belt in front and
for the outer rear seats, the seat belt
tongue is engaged in the belt buckle.
R the front-passenger seat is occupied and
the belt tongue is engaged in the buckle on
the front-passenger side.
The belt tensioners 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 in certain situations where the vehicle over-
turns 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. 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 secure children less than 1.50 m tall
and under twelve years of age on the front-
passenger seat. Exception: if the vehicle is
equipped with automatic child seat recog-
nition on the front-passenger seat 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 children must never travel sitting on the lap
of another occupant. Due to the forces
which occur in the event of a sudden
change of direction, heavy braking or an
accident, it would not be possible to
restrain the 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- 48

Signals from electronic equipment can cause
interference in the automatic child seat rec-
ognition sensor system. This can lead to a
system malfunction. This may cause the
4 PASSENGER AIRBAG OFF indicator
lamp to light up withou tthere being a child
seat with transponders for automatic child
seat recognition fitted. The front-passenger
airbag will not then deploy during an accident.
It is also possible that the 6SRS warning
lamp lights up and/or the 4PASSENGER
AIRBAG OFF indicator lamp does not light up
briefly when you turn the key in the ignition
lock to position 2. If the front-passenger seat of your vehicle
does not have automatic child seat recogni-
tion, this is indicated by a special sticker. The
sticker is affixed to the side of the dashboard
on the front-passenger side. The sticker is
visible when you open the front-passenger
door.
Vehicles without automatic child seat
recognition on the front-passenger seat: if
you turn the key to position 2inthe ignition
lock, the 4PASSENGER AIRBAG OFF indi-
cator lamp lights up briefly but has no func-
tion. It does not indicate that there is auto-
matic child seat recognition on the front-
passenger seat. The automatic child seat recognition sensor
system on the front-passenger seat detects
whether a special Mercedes-Ben
zchild seat
with automatic child seat recognition has
been fitted there. In such cases, 4

ISOFIX child seat securing system for
the rear seats G
WARNING
Ac hild restraint system secured by the ISOFIX
child seat securing system does not provide
sufficient protection for children weighing
more than 22 kg. For this reason, do not
secure children weighing more than 22 kg in
a child restraint system secured by the ISOFIX
child seat securing system. If the child weighs
more than 22 kg, secure the child restraint
system with the vehicle seat belt as well. In
addition, when fitting a child restraint system,
be sure to observe the manufacturer's instal-
lation instructions and the instructions for
correct use of the child restraint system. Children in the vehicle

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, be sure to observe the manufactur-
er's installation instructions and the instruc-
tions for correct use of the child restraint sys-
tem.
For safety reasons, when installing child
restraint systems on the rear seats, only use
child restraint systems with the ISOFIX child
seat securing system, which are specially tes-
ted and approved for Mercedes-Benz vehi-
cles.
An incorrectly fitted child restraint system
could come loose and seriously or even fatally
injure the child or other vehicle occupants.
When fitting the child restraint system, always
make sure that it is engaged correctly in the
securing rings on both sides. G
WARNING
Please note that if child restraint systems, or
their retaining systems, are damaged or sub-
jected to a load in an accident, they may not
be able to provide their protective function.
This could result in serious or even fatal inju-
ries to the secured child in the event of an
accident, heavy braking or a sudden change
in direction.
For this reason, have child restraint systems
and their anchorages which have been dam-
aged or subjected to a loadinana ccident
checked immediately at a qualified specialist
workshop.
! Whe nfitting the child restraint system,
make sure that the seat belt for the centre
seat does not get trapped. Otherwise, the
seat belt could be damaged.
ISOFIX is a standardised securing system for
specially designed child restraint systems on the rear seats. Securing rings for two ISOFIX
child restraint systems are fitted on the left
and right of the rear seats.
