OF91.60-P-1000-01A
Disconnecting airbag, certificate
After the front passenger airbag or emergency tensioning retractor
has been deactivated it must be ensured that the declaration is
signed by the customer.
Reconnection should be stamped and signed on the declaration by
the Mercedes-Benz service station performing the work.
a mb
Declaration
after disconnecting front passenger airbag on request by customer
I have explicitly requested the operation of the passenger airbag and
the passenger emergency tensioning retractor with belt force limiter
to be deactivated.
I have been informed that due to this measure the additional passive
safety guaranteed by the front passenger airbag as well as the front
passenger emergency tensioning retractor with belt force limiter is no
longer available and thereby increases the injury hazard for the
passenger.
Particularly body regions such as head, neck and chest can be
affected by reduced restraint. Direct contact with passenger
compartment components can occur more probably.
I hereby forego all claims against DaimlerChrysler AG that arise from
the deactivation of the passenger airbag and the passenger
emergency tensioning retractor with belt force limiter, whatever the
legal reason for the claim.
Moreover, I acknowledge that I am obligated to indicate to
passengers, any subsequent owner of the vehicle or any person
using the vehicle that this protective function has been deactivated
as well as the associated hazards.
A sticker has been attached to the passenger airbag which may be
removed only when the passenger airbag is reactivated by a
Mercedes-Benz service station.
Disconnection is to be noted in the registration papers.
