If the seat belts are not released:
X Move the backrest or seat back slightly, but
only when the vehicle is stationary.
Seat belt pre-tensioning is reduced and the locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE ®

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.

culty resetting the NECK-PRO head
restraints, have this work carried out at a
qualified specialist workshop. Seat belts

If indicator lamp :lights up red: repeat the
programming process for the correspond-
ing button on the rear-view mirror. When
doing so, vary the distance between remote
control Aand the rear-view mirror.
The required distance between remote
control Aand the integrated garage door
opener depends on the garage door drive
system. Several attempts may be required.
You should test every position for at least
25 seconds before trying another position.
Synchronising the rolling code
Pay attention to the "Important safety notes"
(Y page 553).
If the garage door system uses a rolling code, you will also have to synchronise the garage
door system with the integrated garage door
opener in the rear-view mirror. To do this you
will need to use the programming button on
the door drive control panel. Depending on
the manufacturer, the location of the pro-
gramming button may vary. It is usually loca-
ted on the door drive unit on the garage ceil-
ing.
Familiarise yourself with the garage door
drive operating instructions, e.g. under "Pro-
gramming of additional remote controls",
before carrying out the following steps. Your vehicle must be within range of the
garage door or exterior gate drive. Make sure
that neither your vehicle nor any persons/
objects are present within the sweep of the
door or gate.
X Turn the key to position 2in the ignition
lock (Y page 155).
X Get out of the vehicle.
X Press the programming button on the door
drive unit.
Usually, you now have 30 seconds to ini-
tiate the next step.
X Get into the vehicle.
X Press previously programmed button ;,
= or? of the integrated garage door
opener until the door closes.
The rolling code synchronisation is then
complete.
Problems when programming
If you have problems when programming the
integrated garage door opener, please note
the following:
R Check the transmitter frequency used by
garage door drive remote control Aand
whether it is supported. The transmitter
frequency can usually be found on the back
of the garage door drive remote control.
R Replace the batteries in garage door
remote control A. This increases the like-
lihood that garage door remote control A
will transmit a strong and precise signal to the integrated garage door opener in the
rear-view mirror.
R When programming, hold remote control
A at varying distances and angles from the
button which you are programming. Try var- ious angles at a distance between 5and
30 cm or at the same angle but at varying
distances.
R If there is another remote control for the
same garage door drive, perform the pro-
gramming steps again using this remote
control. Before performing these steps,
make sure that new batteries have been 554
