Declarations of conformity
Wireless vehicle components The following information applies to all com-
ponents of the vehicle and the COMAN
Dsys-
tem which receive and/or transmit radio
waves:
The components of this vehicle which receive
and/o rtransmit radio waves are compliant
with the basic requirements and other rele-
vant provisions of Directive 1999/5/EC. You
can obtain further information from any
Mercedes-Benz Service Centre.
Electromagnetic compatibility The electromagnetic compatibility of the vehi-
cle components has been tested and certified
in accordance with the current version of
Directive 72/245/EE Cor the equivalent
ECE-R 10 regulation. Diagnostics connection
G
WARNING
If you connect equipment to a diagnostics
connection, it can affect the operation of the
vehicle systems. This could compromise the
operating safety of your vehicle while driving.
There is a risk of an accident.
Do not connect any equipment to a diagnos-
tics connection. G
WARNING
Loose equipment or cables hanging from a
device which are connected to a diagnostic
connection could impede pedal clearance.
The equipment or cables could get caught
between the pedals when driving and braking
suddenly. This could impair the function of the
pedals. There is a risk of accident.
Do not attach any equipment or cables in the
driver's footwell. !
If the engine is switched off and equip-
ment on the diagnostics connection is
used, the starter battery may discharge.
The diagnostics connection is only intended
for the connection of diagnostic equipment at
a qualified specialist workshop.
Connecting equipment to the diagnostics
connection can lead to emissions monitoring
information being reset, for example. This
may lead to the vehicle failing to meet the
requirements of the next emissions test dur-
ing the main inspection. Qualified specialist workshop
Aq ualified specialist workshop has the nec-
essary special skills, tools and qualifications
to correctly carry out any necessary work on
your vehicle. This particularly applies to work
relevan tto safety.
Observe the notes in the Service Booklet.
Always have the following work carried out at
a qualified specialist workshop:

Mercedes-Benz recommends that you use a
Mercedes-Benz Service Centre. Vehicle registration
Mercedes-Benz may ask its Service Centres
to carry out technical inspections on certain
vehicles. The quality or safety of the vehicle
is improved as a result of the inspection.
Mercedes-Benz can only inform you about
vehicle checks if it has your registration data. 22
Introduction

cannot provide the intended level of protec-
tion. Do not use head restraint covers.
The NECK-PRO head restraints increase pro-
tectio nto the driver's and the front passeng-
er's head and neck.T he 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 43). Otherwise, the
additional protection will not be available in
the event of another rear-end collision. You
can recognise if NECK-PRO head restraints
have been triggered by the fact that they have
moved forwards and can no longer be adjus-
ted.
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 Repeatt his procedure for the second
NECK-PRO head restraint. Mercedes-Ben
zrecommends that you have
the NECK-PRO head restraints checked at a
qualified specialist workshop after a rear-end
collision.
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.
Therefore, make sure that all occupants —in
particular, pregnan twomen —wear their seat
belts correctly at all times.
R The seat belt must fit snugly on your body
and must not be twisted.Therefore, avoid
wearing bulky clothing, e.g. a winter coat.
The shoulder section of the belt must be
routed across the centre of your shoulder
—onn o account across your neck or under
your arm —and pulled tight against your
uppe rbody. The lap belt must always pass
across your lap as low down as possible, i.e.
over your hip joints —not across your abdo-
men. If necessary, push the seat belt
slightly downwards and adjust it by pulling
it in the direction the seat belt retracts.
R Do not route the seat belt strap over sharp
or fragile objects. Please make sure that
such objects are not on or in your clothing,
e.g. spectacles, pens or keys etc. The seat
belt strap could become damaged and tear
during an accident and you or other vehicle
occupants could be injured. Occupant safety

Rear seat head restraints Important safety notes
G
WARNING
Drive only with the head restraints fitted. This
reduces the risk of injury in the event of an
accident.
Occupants must only travel on seats with
head restraints fitted. Pull the head restraints
up into the upright position. This reduces the
risk of injury to occupants in the event of an
accident.
Ensure that the back of your head is suppor-
ted at eye level by the centre of the head
restraint. This reduces the risk of injury to your head or neck in the event of an accident
or a similar situation.

WARNING
If incident light from headlamps is prevented
from striking the sensor in the rear-view mir-
ror, for instance, by luggage piled too high in
the vehicle, the mirror's automatic anti-dazzle
function will not operate.
Incident light could then blind you. This may
distract you from the traffic conditions and,
as a result, you may cause an accident.
The rear-view mirror and the exterior mirror
on the driver's side automatically go into anti-
dazzle mode if:
R the ignition is switched on and
R incident light from headlamps strikes the
sensor in the rear-view mirror.
i The mirrors do not go into anti-dazzle
mode if reverse gear is engaged or if the
interior lighting is switched on. 100
