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 second row outer seats will ac-
tivate with or without the respective seat belts
fastened.
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.
