occupant in the best position in relation to the
air bag.
The seat belt system comprises:
R Seat belts
R Emergency Tensioning Devices for the front
seat belts and the outer seat belts in the sec- ond row of seats as well as the seat belts in
the third row
R Seat belt force limiters for the front seat belts
and the outer seat belts in the second row of
seats as well as the seat belts in the third row
If the seat belt is pulled out of the belt outlet
quickly or with a jerky movement, the belt
retractor locks. The belt strap cannot be extrac-
ted any further.
The Emergency Tensioning Device tightens the
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 Tensioning Device does not cor- rect an incorrect seat position or the routing of
an incorrectly fastened seat belt.
When triggered, a seat 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 not occupied,
do not engage the seat belt tongue in the
buckle on the front-passenger seat. Other-
wise, in addition to other systems, the Emer-
gency Tensioning Device could also be trig-
gered in the event of an accident and would
need to be replaced.
Important safety notes The use of seat belts and child restraint systems
is required by law in:
R all 50 states
R the U.S. territories
R the District of Columbia
R all Canadian provinces
Even where this is not required by law, all vehicle occupants should correctly fasten their seat
belts before starting the journey. G
WARNING
If the seat belt is not worn correctly, it cannot perform its intended protective function. An
incorrectly fastened seat belt can also cause
injuries, for example, in the event of an acci-
dent or when braking or changing direction
abruptly. This poses an increased risk of injury
or even fatal injury.
Always ensure that all vehicle occupants have their seat belts fastened correctly and are sit- ting properly.
The components of the restraint system work in conjunction with each other. They can only
deploy their protective function if, at all times, all
vehicle occupants:
R have fastened their seat belts correctly
(Y page 47)
R have the seat and head restraint adjusted
properly (Y page 97) G
WARNING
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. G
WARNING
Persons less than 5 ft (1.50 m) tall cannot
wear the seat belt correctly without an addi-
tional and suitable restraint system. If the
seat belt is not worn correctly, it cannot per-
form its intended protective function. An
incorrectly fastened seat belt can also cause
injuries, for example, in the event of an acci-
dent or when braking or changing direction
abruptly. This poses an increased risk of injury or even fatal injury. 46
