NECK-PRO head restraints
The NECK-PRO head restraints increase pro-
tection to the driver's and front passenger's
head and neck. To this end, 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.
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.

sion of a certain severity. This provides better

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 ( Y page 55). Otherwise, the
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.
