* NOTE Damage caused by trapping the
seat belt
If an unused seat belt is not fully retracted, it
may become trapped in the door or in the seat
mechanism.
Always ensure that an unused seat belt
#
is fully retracted.
Information on the belt airbag in the rear seat belt
The BELTBAG identification indicates that a rear
seat belt is equipped with a belt airbag.
When activated, the belt airbag increases the pro-
tected area of the vehicle occupant's ribcage.
& WARNING Risk of injury or death due to
use of a non-approved child restraint sys-
tem
In an accident, the belt airbag may damage a
non-approved child restraint system or a child
restraint system which has not been approved
for use in conjunction with the belt airbag.
For safety reasons, Mercedes-Benz recom-
mends that you only use a child restraint sys-
tem which has been tested and approved by
Mercedes-Benz in combination with a belt air-
bag.
