Mercedes Benz 2008 c300 Manuale Utente

The active head restraints are intended to 
offer the driver and front passenger in-
creased protection from whiplash type in-
juries. In the event of a rear-end collision, 
the active head restraints on the driver’s 
and front passenger’s seats are designed 
to move forward in the direction of travel, 
providing the head with increased support 
earlier on in the collision sequence. The ac-
tive head restraints move forward whether 
the seat is occupied or not.

If the active head restraints have been trig-
gered in an accident, the active head re-
straints must be reset. Otherwise, the 
active head restraints cannot offer any ad-
ditional protection in the event of another 
rear-end collision. 

For information on resetting the activated 
active head restraints, see “Resetting acti-
vated head restraints” (

page 427).

You cannot remove the active head re-
straint on the driver’s and front passen-
ger’s seats.
For removal contact an authorized 
Mercedes-Benz Center.

ment, see “Adjusting rear head restraints”

Do not attach any objects (e.g. hangers) to 

the head restraint posts. Otherwise, the ac-

tive head restraints may not function prop-

erly or offer the degree of protection they 

were designed for in the event of an acci-

dent.

G

Only use seat or head restraint covers which 

have been tested and approved by 

Mercedes-Benz for your vehicle model. 

Using other seat or head restraint covers 

may interfere with or prevent the activation 

of the active head restraints. Contact an 

authorized Mercedes-Benz Center for avail-

ability.

G

For your protection, drive only with properly 

positioned head restraints.

Adjust 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.
