Occupant safety
ț and if the vehicle speed once exceeds
15 mph (25 km/h), the seat belt
telltale < starts flashing and a
warning chime sounds with increasing
intensity for a maximum of 60 seconds
or until the driver’s and passenger’s
seat belts are fastened.
If the driver’s or the passenger’s seat
belt remain unfastened after
60 seconds, the warning chime stops
sounding. The seat belt telltale <
stops flashing but continues to be
illuminated.
The seat belt telltale < will only go out
if both the driver’s and the passenger’s
seat belt (with the passenger seat
occupied) are fastened, or the vehicle is
standing still and a door is opened.
For more information, see the “Practical
hints” section (
୴ page 312).
Emergency Tensioning Device (ETD),
seat belt force limiter
The seat belts are equipped with
emergency tensioning devices and seat
belt force limiters.
The ETD is designed to activate in the
following cases:
ț in frontal or rear-end impacts exceed-
ing the system deployment threshold
ț in side collisions exceeding the deploy-
ment threshold on the far side of the
impact
ț if the restraint systems are operational
and functioning correctly, see 1 in-
dicator lamp (
୴ page 60)
ț in certain vehicle rollovers if the
system determines an additional
degree of protection
The ETDs will only activate if the seat belts
are fastened (latch plate properly inserted
into buckle).
In an impact, 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 reduce the force exerted by
the seat belts on occupants during a crash.
Warning! G
An ETD that was activated must be replaced.
When disposing of the ETD, our safety in-
structions must be followed. These are avail-
able at any authorized Mercedes-Benz
Center.
