NECK-PRO head restraints
Important safety notes
G
WARNING
Only use head restraint covers which have
been tested and approved by Mercedes-Benz
for your vehicle model.
The use of non-approved head restraint cov-
ers may prevent NECK-PRO head restraints
from triggering properly. Consequently, the
NECK-PRO head restraints cannot provide the
intended level of protection.
Consult a Mercedes-Benz Service Centre
regarding availability.
NECK-PRO head restraints reduce the likeli-
hood of head and chest injuries. The NECK-
PRO head restraints on the driver's and front-
passenger seats are moved forwards and
upwards in the event of a rear-end collision of
a certain severity. This provides better head
support.
If the NECK-PRO head restraints have been
triggered in an accident, reset the NECK-PRO
head restraints on the driver's and front-
passenger seat (
page 57). Otherwise, the
Y
additional protection will not be available in
the event of another rear-end collision. You
can recognise when NECK-PRO head
restraints have been triggered by the fact that
they have moved forwards and can no longer
be adjusted.
Mercedes-Benz recommends that you have
the NECK-PRO head restraints checked at a
Occupant safety
qualified specialist workshop after a rear-end
collision.

restraints

X

Repeat this procedure for the second
X

culty resetting the NECK-PRO head
restraints, have this work carried out at a
qualified specialist workshop.
