eyes, skin, clothing, or respiratory system. 
In case it does, immediately flush the affect-
ed area with water, and seek medical help if 
necessary.

Warning!
G
An emergency tensioning device (ETD) that 
was activated must be replaced. 
When scrapping the emergency tensioning 
device, our safety instructions must be fol-
lowed. These are available at your autho-
rized Mercedes-Benz Center.!Do not place objects heavier than 20 
lbs (9 kg) on the front passenger seat. 
This could cause the front or side im-
pact airbag on the front passenger side 
to deploy in a crash which exceeds the 
system's deployment threshold.
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 inadvertently 
occupying the rear storage area.
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 using the buttons pro-
vided to avoid damaging the hydraulics.
iWhen the roll bar is raised automatical-
ly, you will hear a ratcheting sound.
