NECK-PRO head restraints
The NECK-PRO head restraints increase protection 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.
 WARNING
 WARNING
 
Do not secure any objects (e.g. coat hangers) 
on the NECK-PRO head restraints. Otherwise, 
the NECK-PRO head restraints may not 
function properly, or in the event of a rear-end 
collision may not be able offer the level of 
protection they are designed to provide.
 WARNING
 WARNING
 
Seat or head restraint covers can cause a 
malfunction when the NECK-PRO 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 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 have been triggered in an accident, reset the NECK-PRO head restraints on the driver’s and frontpassenger seat (Y page 51). Otherwise, the additional protection will not be available in the event of another rear-end collision. You can recognize when NECK-PRO head restraints have been triggered by the fact that they have moved forwards and can no longer be adjusted.
 WARNING
 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.
