On-Board diagnostic interface
G
WARNING
If you connect equipment to the on-board
diagnostic interface, it can affect the opera-
tion of the vehicle systems. This can impair
the operating safety of your vehicle while driv-
ing. There is a risk of accident.
Do not connect any equipment to the on-
board diagnostic interface. G
WARNING
Loose equipment or equipment cables which
are connected to the on-board diagnostic
interface may infringe on the space around
the pedals. The equipment or the cables could
get between the pedals in the event of sudden
braking or acceleration. You may then no lon-
ger be able to brake, operate the clutch or
accelerate as intended. There is a risk of acci-
dent.
Do not attach any equipment or cables in the
driver footwell.
Connecting equipment to the on-board diag-
nostic interface can lead to emissions moni-
toring information being reset .This may lead
to the vehicle failing to meet the require-
ments at the next emissions control test or
main inspection.
If the engine is switched off and equipment
on the on-board diagnostic interface is used,
the starter battery may discharge.
The on-board diagnostic interface is intended
for the connection of diagnostic equipment at
a qualified specialist workshop. Qualified specialist workshop
Aq ualified specialist workshop has the nec-
essary specialist knowledge, tools and quali-
fications to correctl ycarry out the work
required on your vehicle .This is especially the
case for work relevant to safety.

WARNING
Various warning stickers are affixed to your
vehicle. Their purpose is to draw your atten-
tion, and the attention of others, to various
dangers. Therefore, do not remove any warn-
ing stickers unless the sticker clearly states
that you may do so.
If you remove the warning stickers, you or
others could be injured by failing to recognise
certain dangers. 28
Introduction

PRE-SAFE
®
takes the following measures
depending on the hazardous situation detec-
ted:
R the fronts eat belts are pre-tensioned.
R vehicles with the memory function :it
adjusts the front-passenger seat if it is in
an unfavourable position.
R if the vehicle skids, the sliding sunroof/
panorama sliding sunroo fand the side win-
dows are closed so tha tonly a small gap
remains.
If the hazardous situatio npasses without
resulting in an accident, PRE-SAFE ®
slackens
the belt pretensioning .The air pressure in the
side bolsters on the multicontour seat is
reduced again. All settings made by PRE-
SAFE ®
can then be reversed.
If the seat belts are not released:
X Move the backrest or seat back slightly, but
only when the vehicle is stationary.
The belt pretensioning is reduced and the
locking mechanism is released. G
WARNING
When adjusting the seat, make sure that
nobody can become trapped.
! Make sure that there are no objects in the
footwell or behind the seats when moving
the seat back. There is a risk that the seats
and/or the objects could be damaged.
More information about seat-belt adjust-
ment,ac onvenience function integrated into
PRE-SAFE ®
, can be found in the "Seat-belt
adjustment" section (Y page 55).NECK-PRO head restraint/NECK-PRO
luxury head restraint (except AMG
vehicles)
NECK-PRO head restraints/NECK-PRO luxury
head restraints increase protection of the
driver's and front-passenger's head and
neck.Int he event of a rear collision of a cer-
tain severity, the NECK-PRO head restraints/ NECK-PRO luxury head restraints on the driv-
er's and front-passenger seats are moved for-
wards and upwards. This provides better
head support. 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/
NECK-PRO luxury head restraints from trig-
gering properly. The NECK-PRO head
restraints/NECK-PRO luxury head restraints
can therefore not provide the intended pro-
tection.
Consult a Mercedes-Benz Service Centre
regarding availability.
If the NECK-PRO head restraints/NECK-PRO
luxury head restraints have been triggered in
an accident, reset the NECK-PRO head
restraints/NECK-PRO luxury head restraints
on the driver's and front-passenger seats
(Y page 52). Otherwise, the additional pro-
tection will not be available in the event of
another rear-end collision. NECK-PRO head
restraints/NECK-PRO luxury head restraints
that have been triggered are moved forwards
and can no longer be adjusted. Resetting
atriggered NECK-PRO head
restraint/NECK-PRO luxury head

Important safety notes Mercedes-Benz recommends tha
tyou have
NECK-PRO head restraints/NECK-PRO luxury
head restraints checked at a qualified spe-
cialist workshop, e.g. a Mercedes-Benz
Service Centre, if your vehicle is involved in a
rear-end collision. 52
