MERCEDES-BENZ G-CLASS SUV 2012 Workshop Manual

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
Children in the vehicleSafety

tion instructions and the correct use of the
child restraint system.
Child restraint systems shoul dbe 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-Benz vehicles. G
WARNING
When leaving the vehicle, it can still roll away
despite being braked by the HOLD function if:
R there is a malfunction in the system or in
the voltage supply
R the HOLD function is deactivated by the
accelerator pedal being depressed, e.g. by
a vehicle occupant
R the electrical system in the engine com-
partment, the battery or the fuses are tam-
pered with
R the battery is disconnected
There is a risk of an accident.
Before leaving the vehicle, always deactivate
the HOLD function and secure the vehicle
from rolling away. 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 a braking manoeuvre
R a sudden change of direction
Do not carry heavy or hard objects in the vehi-
cle interior unless they are secured. You will find further information under "Loading guide-
lines" in the index.
If a child is travelling in your vehicle, secure
the child using a child restraint system which
is appropriate to the size, age and weight of
the child and recommended for Mercedes-
Benz vehicles. You should preferably fit the
restraint system to a suitable rear seat. Make
sure that the child is secured in a child
restraint system throughout the trip.
Mercedes-Benz recommends that you only
use the child restraint systems listed under
(Y page 56).
You can obtain information about the correct
child restraint system 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.
Child restraint system on the front-
passenger seat G
WARNING
If the front-passenger airbag is not disabled:
R a child secured in a child restraint system
on the front-passenger seat could be seri-
ously and even fatally injured by the front-
passenger airbag deploying. This is espe-
cially a risk if the child is in the immediate
vicinity of the front-passenger airbag when
it deploys.
R never secure a child on the front-passenger
seat in a rearward-facing child restraint sys-
tem. Only secure a rearward-facing child
restraint system on a suitable rear seat.
R always move the front-passenger seat to
the rearmost position if you secure a child
in a forward-facing child restraint system
on the front-passenger seat. Children in the vehicle

WARNING
If the 4 PASSENGER AIRBAG OFF indica-
to rlamp does no tlight up when the child
restraint system is fitted, the front-passenger
airbag has not been disabled. If the front-
passenger airbag deploys, the child could be
seriously or even fatally injured.
Proceed as follows:
R do not use a rearward-facing child restraint
system on the front-passenge rseat.
R fit a rearward-facing child restraint system
on a suitable rear seat.
or
R only use a forward-facing child restraint
system on the front-passenger seat and
move the front-passenger seat to the rear-
most position.
R have the automatic child seat recognition
checked at a qualified specialist workshop.
To ensure that the automatic child seat rec-
ognition on the front-passenger seat func-
tions/communicates correctly, never place
objects, e.g. a cushion, under the child
restraint system. The entire base of the child
restraint system must always rest on the seat
cushion. An incorrectly fitted child restraint
system cannot perform its intended protec-
tive function in the event of an accident, and
could lead to injuries. G
WARNING
Do not place electronic devices on the front-
passenger seat, e.g.:
R laptops, when switched on
R mobile phones
R cards with transponders, e.g. ski passes or
access cards 50
Children in the vehicleSafety

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
PASSENGER AIRBAG OFF indicator lamp :
lights up. The front-passenger front airbag is
disabled.

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
