Mercedes-Benz S-Sedan 2015 Owners Manual - Manual (Page 48)

Depending on the person in the front-
passenger seat, the front-passenger front air
bag is either enabled or disabled. You must
make sure of this both before and during a
journey.
R
Children in a child restraint system:
whether the front-passenger front air bag is
enabled or disabled depends on the instal-
led child restraint system, and the age and
size of the child. Therefore, be sure to
observe the notes on the "Occupant clas-
sification system (OCS)" (
Y
page 54) and
on "Children in the vehicle" (
Y
page 63).
There you will also find instructions on
backwards- and forwards-facing child
restraint systems on the front-passenger
seat.
R
All other persons: depending on the clas-
sification of the person in the front-
passenger seat, the front-passenger front
air bag is enabled or disabled
(
Y
page 54). Be sure to observe the notes
on "Seat belts“ (
Y
page 46) and "Air bags"
(
Y
page 51). There you can also find infor-
mation on the correct seat position.
Seat belts
Introduction
A correctly fastened seat belt is the most
effective means of restraining the movement
of vehicle occupants in the event of an acci-
dent or if the vehicle rolls over. This reduces
the risk of vehicle occupants coming into con-
tact with parts of the vehicle interior or being
thrown from the vehicle. The seat belt also
helps to keep the vehicle occupants in the
best position in relation to the deploying air
bag.
The seat belt system consists of:
R Seat belts
R
Emergency Tensioning Devices for the
front seat belts and the outer seat belts in
the rear
R Seat belt force limiter for the front seat
belts and the outer seat belts in the rear
R
Belt bags for the outer seat belts in the rear
compartment depending on the vehicle's
equipment
If the seat belt is pulled quickly or sharply
from the belt sash guide, the inertia reel
locks. The belt strap cannot be pulled out fur-
ther.
The Emergency Tensioning Device tightens
the seat belt to lie close against your body in
the event of a collision. However, it does not
pull the vehicle occupants back towards the
seat backrest.
The Emergency Tensioning Device also does
not correct an incorrect seat position or the
belt path of a seat belt that is worn incor-
rectly.
When triggered, seat belt force limiters help
to reduce the force exerted by the seat belt on
the vehicle occupant.
The seat belt force limiters for the front seats
are synchronized with the front air bags,
which absorb part of the deceleration force.
This makes it possible to reduce the forces to
which vehicle occupants are subjected during
an accident.
! If the front-passenger seat is unoccupied,
do not insert the belt tongue into the buckle
of the front-passenger seat. This may oth-
erwise lead to the triggering of the Emer-
gency Tensioning Device in the event of an
accident, which will then need to be
replaced.
Important safety notes
The use of seat belts and infant and child
restraint systems is required by law in:
R
all 50 states

R the District of Columbia
R all Canadian provinces
