vehicles) - Occupant safety - Safety - Mercedes-Benz C-Class Owners ManualMercedes-Benz C-Class: NECK-PRO head restraints/NECKPRO luxury head restraints (except AMG vehicles)

NECK-PRO head restraints/NECK-PRO luxury head restraints increase protection of the driver's and front-passenger's head and neck. In the event of a rear collision of a certain severity, the NECK-PRO head restraints/NECK-PRO luxury head restraints on the driver's and front-passenger seats are moved forwards and upwards. This provides better head support.

WARNING
Do not attach any objects (e.g. a coat hanger) to the NECK-PRO head restraints/NECK-PRO luxury head restraints. Otherwise, the NECK-PRO head restraints/NECK-PRO luxury head restraints may not function properly and in the event of a rear-end collision may not offer the protection they are designed to provide.

WARNING
Seat or head restraint covers can cause a malfunction when the NECK-PRO head restraints/NECK PRO luxury head restraints are activated or when the side impact air bags or pelvis air bags are deployed, or they can prevent this completely. The NECK-PRO head restraints/NECK PRO luxury head restraints or side impact air bags/pelvis air bags can therefore not provide the intended protection.
Do not use any seat or head restraint covers.

If the NECK-PRO head restraints/NECK-PRO luxury head restraints have been triggered in an accident, reset the NECK-PRO head restraints/NECK-PRO luxury 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. NECK-PRO head restraints/NECK-PRO luxury head restraints that have been triggered are moved forwards and can no longer be adjusted.

WARNING
For your protection, drive only with properly positioned head restraints.
Adjust the head restraint so that it is as close to the head as possible and the center of the head restraint supports the back of the head at eye level. This will reduce the potential for injury to the head and neck in the event of an accident or similar situation.
