In an impact, emergency tensioning devic-
es remove slack from the seat belts. Seat
belt force limiters reduce the peak force
exerted by the seat belts on occupants
during a crash.
Automatic comfort-fit feature seat belt
An automatic comfort-fit feature for front
seats reduces the retracting force of the
seat belts when they are in normal use.
Preventive occupant safety
(PRE-SAFE
®
)
Your vehicle automatically takes preven-
tive measures to better protect the occu-
pants in the following hazardous
situations:
ț You execute an emergency braking ma-
neuver and the Brake Assist System
(
୴ page 99) is activated.
ț The PRE-SAFE
®
system detects a criti-
cal driving dynamics situation.

The ETDs for the front seats will only acti-
vate if the front seat belts are fastened (latch
plate properly inserted into buckle).
The ETDs for the rear outer seats will activate
with or without the respective seat belts fas-
tened.
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.
Warning! G
The PRE-SAFE
®
system is intended to re-
duce the effects of a crash on properly
seat-belted vehicle occupants. Despite hav-
ing the PRE-SAFE
®
system in your vehicle,
the possibility of injuries occurring as a re-
sult of an accident cannot be eliminated.
Therefore, you should always drive carefully
and adjust your driving to the prevailing
road, weather, and traffic conditions.
