2017 MERCEDES-BENZ C-Class COUPE height

The seat belt system comprises:
RSeat belts
REmergency TensioningDevices and seat belt
force limiters
If the seat belt is pulled out of the belt outlet
quickly or with ajerk ym ovement, the belt
retractor locks. The belt strap cannot be extrac-
ted any further.
The Emergency TensioningD evice tightensthe
seat belt in an accident ,pulling the belt close
against the body. However it does not pull the
vehicle occupant back in the direction of the
backrest.
The Emergency TensioningD evice does not cor-
rect an incorrect seat position or the routing of
an incorrectly fastened seat belt.
When triggered, aseat belt force limiter helps 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 can
reduce the force exerted on the vehicle occu-
pants 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 otherwise
lead to the triggerin gofthe Emergency Ten-
sioning Device in the event of an accident,
which will then need to be replaced.
Important safety notes
The use of seat belts and child restraint systems
is required by law in:
Rall 50 states
Rthe U.S. territories
Rthe District of Columbia
Rall Canadian provinces
Even where this is not required by law, all vehicle
occupantss hould correctly fasten their seat

GWARNING
If the seat belt is incorrectly fastened, it can-
not protec tasintended. Furthermore, an
incorrectly fastened seat belt can cause addi-
tional injury, for example, in an accident ,dur-
ing braking or when abruptly changing direc-
tion. This poses an increased risk of injury or
even fatal injury.
Make sure that all vehicle occupantsa re
seated properly with acorrectly fastened seat
belt.
GWARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident ,you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seat belt is routed
across the center of your shoulder.
GWARNING
Persons under 5ft(1.50 m) in height cannot
fasten the seat belt correctly without an addi- tional suitable restraint system. If the seat
belt is incorrectly fastened, it cannot protect

tened seat belt can cause additional injury, for
example, in an accident ,during braking or an
abrupt change of direction .This poses an
increased risk of injury or even fatal injury.
For this reason, alwayss ecure persons under
5ft( 1.50 m) in height in suitable restraint
systems.
If ac hild younger than twelve years old and
under 5ft(1.50 m)in height is travelingint he
