67 Safety and Security
Occupant safety
Emergency tensioning device (ETD), 
seat belt force limiter
The seat belts for the front and rear seats 
are equipped with emergency tensioning 
devices and belt force limiters.
The ETD is designed to activate in the fol-
lowing cases when the seat belt are fas-
tened and:
in frontal or rear-end impacts 
exceeding a preset severity level
if the restraint systems are operational 
and functioning correctly. See 
1indicator lamp (
page 58)In an impact, emergency tensioning devic-
es remove slack from the belts in such a 
way that the seat belts fit more snugly 
against the body. Belt force limiters reduce 
the force exerted by the seat belts on oc-
cupants during a crash.
Never use a seat belt for more than one 
person at a time. Do not fasten a seat 
belt around a person and another per-
son or other objects.
Belts should not be worn twisted. In a 
crash, you wouldn’t have the full width 
of the belt to manage impact forces. The 
twisted belt against your body could 
cause injuries.
Pregnant women should also use a 
lap-shoulder belt. The lap belt portion 
should be positioned as low as possible 
on the hips to avoid any possible pres-
sure on the abdomen.
Never place your feet on the instrument 
panel or on the seat. Always keep both 
feet on the floor in front of the seat.
Warning!
G
An emergency tensioning device (ETD) that 
was activated must be replaced.
When disposing of the emergency tension-
ing device, our safety instructions must be 
followed. These are available at your autho-
rized Mercedes-Benz Center.
