The seat belts for the following seats are
equipped with ETDs and seat belt force
limiters:
R
front seats
R
outboard second-row seats
R
third-row seats
The ETDs are designed to activate in the
following cases:
R
in frontal or rear-end impacts exceeding
the system’s preset deployment threshold
R
in side impacts exceeding the system’s
preset deployment threshold on the far
side of the impact
R
in certain vehicle rollovers
R
if the restraint systems are operational and
functioning correctly, see “SRS indicator
lamp” (
The ETDs for the front seats will only activate
if the front seat belts are fastened (latch plate
properly inserted into buckle).
The ETDs for the rear outer seats (second-row
seats) or rear seats (third-row seats) will
activate with or without the respective seat
belts fastened.
In an impact, the ETDs remove slack from the
seat belts in such a way that the seat belts fit
more snugly against the body. Seat belt force
limiters, when activated, are employed to
help reduce the peak force exerted by the
seat belts on occupants during a crash.
i
The ETDs do not correct an incorrect seat
position or incorrectly worn seat belts.
The ETDs do not pull occupants back
toward the seat backrest.
Pyrotechnic ETDs that were activated must be
replaced.
For your safety, when disposing of the
pyrotechnic ETDs always follow our safety
instructions. These are available at any
authorized Mercedes-Benz Center.
The PRE-SAFE
®
system has electrically
operated reversible pre-tensioners that do
not require replacement after activation.
The PRE-SAFE
®
system is intended to reduce
the effects of an accident on vehicle
occupants who are wearing their seat belt
properly. Despite your vehicle being equipped
with the PRE-SAFE
®
system, the possibility of
personal injuries occurring as a result of an
accident cannot be eliminated. Therefore,
always drive carefully and adjust your driving
to the prevailing road, weather, and traffic
conditions.
The PRE-SAFE
®
system takes preventive
measures to better protect the occupants
from the possibility of personal injuries in the
following hazardous situations:
R
emergency braking maneuvers with the
Brake Assist System (BAS) (
activated
R
critical dynamic driving situations, e.g.
when the vehicle has been caused to
understeer or oversteer because it has
exceeded its physical limitations or in case
of evasive steering maneuvers at speeds
above approximately 85 mph (140 km/h)
PRE-SAFE
®
takes the following measures
when it is activated:
R
The front seat belts are pre-tensioned
automatically.
R
Vehicles with front passenger seat memory
function: If the passenger seat is in an
unfavorable position, the seat will be
adjusted to a position that seeks to better
protect the occupant.
