Mercedes Benz 2009 M-Class User Manual

You cannot remove the active head 
restraint on the driver’s and front 
passenger’s seats.
For removal of the active head restraints 
we recommend that you contact an 
authorized Mercedes-Benz Light Truck 
Center.

For information on head restraint adjust-
ment, see “Seats” (

컄

page 43).

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

컄

page 479).

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

the head restraints posts. Otherwise, the 

active head restraints may not be able to 

function properly or offer the intended 

degree of protection in the event of an 

accident.

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.

G

Do not drive the vehicle without the seat 

head restraints installed when the rear seats 

are occupied. Head restraints are intended 

to help reduce injuries during an accident.

With a rear seat occupied, make sure to 

move the respective head restraint up from 

the lowest non-use position and have the 

occupant adjust the head restraint properly.

For your protection, drive only with properly 

positioned head restraints.

Adjust the head restraint in such a way that 

it is as close to the head as possible and 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.
