Changing the batteries
304 Resetting triggered NECK-PRO head
restraints
If the NECK-PRO head restraints are triggered
in an accident, you must reset the head
restraints on the driver's and front-passenger
seats. Otherwise, the additional protection
will not be available in the event of another
rear-end collision. You can recognise when
head restraints have been triggered by the
fact that they have been moved forwards and
can no longer be adjusted.
Mercedes-Benz recommends that you have
NECK-PRO head restraints checked at a quali-
fied specialist workshop, e.g. a Mercedes-
Benz Service Centre, following a rear-end
collision.
i This work requires a lot of strength. If you
have difficulty resetting the head
restraints, have this work carried out at a
qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre. 1
