(Y page 59). NECK-PRO head restraints
Important safety notes 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.
NECK-PRO head restraints reduce the likeli-
hood of head and chest injuries. 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.
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 57). 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 longerbe adjusted.
Mercedes-Benz recommends that you have
the NECK-PRO head restraints checked at a qualified specialist workshop after a rear-end
collision.
Resetting triggered NECK-PRO head
restraints X
Tilt the top of the NECK-PRO head restraint
cushion forwards in the direction of
arrow :.
X Push the NECK-PRO head restraint cushion
down in the direction of arrow ;as far as
it will go.
X Firmly push the NECK-PRO head restraint
cushion back in the direction of arrow =
until the cushion engages.
X Repeat this procedure for the second
NECK-PRO head restraint.
i Resetting the NECK-PRO head restraints
requires a lot of strength. If you have diffi-
culty resetting the NECK-PRO head
restraints, have this work carried out at a
qualified specialist workshop. Seat belts
Important safety notes G
WARNING
A seat belt which is not worn correctly, or
which has not been engaged in the seat belt
buckle correctly, cannot provide the intended level of protection. Under certain circumstan-
ces, this could cause severe or even fatal inju- ries in the event of an accident. Occupant safety

reduces the risk of vehicle occupants coming
into contact with parts of the vehicle interior.
Fastening seat belts X
Adjust the seat and move the backrest to
an almost vertical position (Y page 112).
X Pull the seat belt smoothly through seat
belt guide :.
X Without twisting it, guide the shoulder sec-
tion of the seat belt across the middle of
your shoulder and the lap section across
your pelvis.
X Engage belt tongue ;in buckle =.
Seat belt adjustment: if necessary, the driv- er's and front-passenger seat belts auto-
matically adjust to the upper body
(Y page 59).
X If necessary, pull upwards on the shoulder
section of the seat belt to tighten the belt
across your body.
Information about releasing the seat belt with
release button ?(Ypage 59).
Seat belt adjustment The seat-belt adjustment function adjusts the
driver's and front-passenger seat belt to the
upper body of the occupants. The belt strap is tightened slightly when:
R you engage the belt tongue in the belt
buckle and you then turn the key to position
2 in the ignition lock.
R the key is in position 2in the ignition lock
and you then engage the belt tongue in the buckle.
The seat-belt adjustment will apply a certain
tightening force if any slack is detected
between the occupant and the seat belt. Do
not hold on to the seat belt tightly while it is
adjusting. You can switch the belt adjustment
on and off using the on-board computer
(Y page 243).
The seat belt adjustment is a convenience
function integrated in PRE-SAFE ®
(preventa-
tive occupant protection). More information
on PRE-SAFE ®
(Y page 56).
Releasing the seat belts !
Make sure that the seat belt is fully rolled
up. Otherwise, the seat belt or belt tongue
will be trapped in the door or in the seat
mechanism. This could damage the door,
the door trim panel and the seat belt. Dam-
aged seat belts can no longer fulfil their
protective function and must be replaced.
Visit a qualified specialist workshop. Occupant safety
