2013 MERCEDES-BENZ G-Class SRS

Your vehicle is equipped with a BabySmart™
system.
Special child restraint systems which are
compatible with BabySmart™ are necessary
for deactivating the front-passenger air bag.
When the special BabySmart™-compatible
child restraint system is installed correctly
and
is recognized by the sensor system in the
front-passenger seat, the front-passenger air
bag is deactivated. In this case, 45
indicator lamp : lights up. If you have any
questions regarding the special BabySmart™-
compatible child restraint systems, consult
an authorized Mercedes-Benz Center.
If the SmartKey has been removed from the
ignition lock or is in position 0, 45
indicator lamp : does not light up.
The system does not disable:
R the window curtain air bag
R the Emergency Tensioning Device
System self-test G
WARNING
Do not leave any switched on notebooks,
mobile phones, electronic tags (e.g. a ski
pass) or similar electronic devices on the
front-passenger seat. Signals emitted from
such devices can interfere with the
BabySmart™ air bag deactivation system.
Such interference can lead to the 45
indicator

lamp not lighting up during the self-
test.
If the + SRS warning lamp and the
4/ indicator lamp light up simultaneously in the instrument cluster, the
system is malfunctioning. The front-
passenger

air bag could deploy without cause,
or may fail to deploy in the event of an
accident.
Have the system checked as soon as possible
at an authorized Mercedes-Benz Center.
The 45 indicator lamp lights up when
the SmartKey is turned to position 1 or 2 in
the ignition lock.
The 45 indicator lamp goes out after
approximately six seconds.
If the 45 indicator lamp does not light
up or is always lit, then the system is
malfunctioning. Have the BabySmart™
system checked at an authorized Mercedes-
Benz Center before transporting a child on
the front-passenger seat.

air bag deactivation system" ( Y page 47).46

wearer is in a position that is as upright as
possible and the seat belt is properly
positioned on the body.
G
WARNING
Never let more people ride in the vehicle than
there are seat belts available. Make sure
everyone riding in the vehicle is correctly
restrained with a separate seat belt. Never
use
a seat belt for more than one person at a
time. G
WARNING
Always have damaged seat belts or seat belts
that have been subjected to a load in an
accident replaced and the anchorages
checked.
Only use seat belts that have been approved
by Mercedes-Benz.
Never tamper with seat belts. This can result
in the unintended deployment of the
Emergency Tensioning Devices or the failure
to deploy when necessary.
Do not bleach or dye seat belts, as this may
severely weaken them. In the event of a
collision, they may be unable to provide
adequate protection.
Have all work carried out only by qualified
technicians. Consult a qualified specialist
workshop.
The

use of infant or child restraints is required
by law in all 50 states, the District of
Columbia, all U.S. territories and all Canadian
provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts
fastened when the vehicle is in motion.
i See "Children in the vehicle"
(Y page 54) for further information on
infants and children traveling in the vehicle,
as well as on child restraint systems. Correct use of the seat belts G
WARNING
CORRECT USE OF SEAT BELTS
R Seat belts only work properly if they are
fastened

correctly. Never wear seat belts in
any other way than as described in this
section, as that could result in serious
injuries in the event of an accident.
R All occupants should wear their seat belt at
all times, because seat belts help reduce
the likelihood of and potential severity of
injuries in accidents, even if the vehicle
overturns. The restraint system installed is
equipped with SRS (driver's air bag, front-
passenger air bag, window curtain air
bags), belt tensioners and belt force
limiters.
The system is designed to enhance the
protection offered to occupants who are
wearing their seat belts correctly, in certain
frontal impacts (front air bags and belt
tensioners) and side impacts (window
curtain air bags and belt tensioners) which
exceed preset deployment thresholds.
R Never route the shoulder section of the
seat belt under your arm, across your neck
or anywhere other than across your
shoulder. In the event of a frontal impact,
your body would be moved too far forward.
This would increase the risk of head and
neck injuries. The seat belt would then
apply excessive force to the ribs or
abdomen which could cause severe
internal injuries to organs such as the liver
or spleen.
Adjust the seat belt so that the upper part
of the belt is as close as possible to the
center of the shoulder. It should not touch
the neck. Never route the belt under the
shoulder. The height of the belt outlet can
be altered to ensure correct usage.
R The lap belt should be routed as low as
possible across the hips, not across the
abdomen. If the lap belt is routed across the Occupant safety

!
If the front-passenger seat is not
occupied, do not engage the seat belt
tongue in the buckle on the front-
passenger
seat. Otherwise, the Emergency
Tensioning Device could be triggered in the
event of an accident.
X In order to ensure that the pyrotechnic
Emergency Tensioning Devices have not
been triggered, always have the seat belts
checked after an accident.
If the Emergency Tensioning Devices have
been triggered, they must be replaced.
The seat belts for the front seats and rear
outer
seats are equipped with ETDs and seat
belt force limiters.
The ETDs on the driver's and front-passenger
seat consist of pyrotechnic belt buckle
tensioners and belt anchor installation
tensioners that are triggered together. The
belt buckle tensioner is mounted on the B-
pillar and the belt anchor installation is
mounted on the side of the seat. After
deploying, both tensioners must always be
replaced.
The ETDs tighten the seat belts in an accident,
pulling them close against the body.
The ETDs do not correct incorrect seat
positions or incorrectly fastened seat belts.
The ETDs do not pull vehicle occupants back
towards the backrest.
When triggered, seat belt force limiters help
to reduce the peak force exerted by the seat
belt on the vehicle occupant.
The front seat belt force limiters are
synchronized with the front air bags, which
take on a part of the deceleration force. Thus,
the force exerted on the occupant is
distributed over a greater area.
The ETDs can only be activated when:
R the SmartKey is in position 1 or 2 in the
ignition lock.
R the restraint systems are operational; see
"SRS warning lamp" ( Y page 39). R
the
belt tongue is engaged in the buckle on
each of the lap-shoulder belts in the front.
R the front-passenger seat is occupied and
the belt tongue is engaged in the buckle on
the front-passenger side
The Emergency Tensioning Devices are
triggered depending on the type and severity
of an accident, if:
R in the event of a head-on or rear-end
collision, the vehicle decelerates or
accelerates rapidly in a longitudinal
direction during the initial stages of the
impact
R if, in the event of a side impact, on the side
opposite the impact the vehicle
decelerates or accelerates rapidly in a
lateral direction
R in certain situations where the vehicle
overturns and the system determines that
it can provide additional protection
If the ETDs 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 6 SRS warning lamp

Important safety notes G
WARNING
According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children

be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an appropriate
infant restraint, toddler restraint, or booster
seat recommended for the size and weight of
the child. 54
