Occupant safety
Emergency tensioning device (ETD), 
seat belt force limiter
The seat belts are equipped with emergen-
cy tensioning devices and belt force 
limiters.
The ETD is designed to activate in the fol-
lowing cases: 
in frontal or rear-end impacts exceed-
ing the system deployment threshold
if the restraint systems are operational 
and functioning correctly, see 
1 in-
dicator lamp (
in certain vehicle rollovers if the sys-
tem determines an additional degree of 
protection
When activated, emergency tensioning de-
vices 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.
Automatic comfort-fit feature seat belt
The automatic comfort-fit feature reduces 
the retracting force of the seat belts when 
they are in normal use.

The ETDs will only activate if the seat belts 
are fastened (latch plate properly inserted into 
buckle).
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
This vehicle is a two occupant vehicle. The 
rear storage area is not intended for use by 
occupants and is not equipped for properly 
seating or restraining occupants. Thus this 
area should never be used by any persons.
Before operating the roll bar switch make 
sure that the roll bar’s path is clear and no 
persons are injured by the moving roll bar 
due to inattention. Raising or lowering of the 
roll bar could injure someone in it’s proximi-
ty.
For your own safety, we recommend to drive 
with the roll bar raised if the outside temper-
ature is below +5°F (-15°C).
!
If the outside temperature falls below +5°F 
(-15°C), the roll bar must be raised manually us-
ing the buttons provided to avoid damaging the 
hydraulics.
