WARNING
If you connect equipment to a diagnostics
connection in the vehicle, it can affect the
operation of the vehicle systems. This may
affect the operating safety of the vehicle.
There is a risk of an accident.
Do not connect any equipment to a diagnos-
tics connection in the vehicle. G
WARNING
Objects in the driver's footwell may restrict
the clearance around the pedals or block a
depressed pedal. This jeopardises the oper-
ating and road safety of the vehicle. There is a risk of an accident.
Stow all objects securely in the vehicle so that
they do not get into the driver's footwell.
Always fit the floormats securely and as pre-
scribed in order to ensure that there is always sufficient room for the pedals. Do not use
loose floormats and do not place several floor- mats on top of one another.
! If the engine is switched off and equip-
ment on the diagnostics connection is
used, the starter battery may discharge.
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
A qualified 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
relevant to safety.
Observe the notes in the Service Booklet.
Always have the following work carried out at a qualified specialist workshop:
R work relevant to safety
R service and maintenance work R
repair work
R modifications, installations and conver-
sions
R work on electronic components
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.
It is possible that your vehicle has not yet
been registered in your name in the following
cases:
R if your vehicle was not purchased at an
authorised specialist dealer.
R if your vehicle has not yet been examined at
a Mercedes-Benz Service Centre.
It is advisable to register your vehicle with a
Mercedes-Benz Service Centre.
Inform Mercedes-Benz as soon as possible
about any change in address or vehicle own-
ership. You can do this at a Mercedes-Benz
Service Centre, for example. Correct use
If you remove any warning stickers, you or
others could fail to recognise certain dangers.
Leave warning stickers in position.
Observe the following information when driv- ing your vehicle:
R the safety notes in this manual
R the technical data in this manual
R traffic rules and regulations
R laws and safety standards pertaining to
motor vehicles 26
Introduction

Useful information

els, series and optional equipment for your
vehicle that were available at the time of
going to press. National variations are pos- sible. Note that your vehicle may not be
equipped with all of the functions descri-
bed. This is also the case for systems and
functions relevant to safety.

ist workshops: (Y page 26). Panic alarm

Introduction to the restraint system
The restraint system reduces the risk of vehi- cle occupants coming into contact with parts
of the vehicle's interior in the event of an
accident. Furthermore, the restraint system
can also reduce the forces to which vehicle
occupants are subjected during an accident.
The restraint system includes:
R Seat belt system
R Airbags
R Child restraint system
R Child seat securing system
The various components of the restraint sys-
tem work complementary to one another. It
can only provide maximum protection if all
vehicle occupants:
R have their seat belt correctly fastened
(Y page 45)
R have correctly adjusted their seat and head
restraint (Y page 105).
As the driver, you must also ensure that the
steering wheel is correctly adjusted. Observe
the information relating to the correct driver's
seat position (Y page 104).
Additionally, you must ensure that an airbag
can deploy freely (Y page 48).
An airbag is supplementary to a correctly fas- tened seatbelt and, as an additional safety
device, provides greater protection for vehi-
cle occupants in an accident situation. If the
protection provided by the seat belt is suffi-
cient, the airbags do not deploy. Furthermore,
in the event of an accident, only airbags which
provide greater protection in the given acci-
dent situation deploy. However, seat belts
and airbags generally do not protect against
objects penetrating the vehicle from the out- side.
Information on how the restraint system
operates can be found in "Deployment of the
seat belt tensioner and airbags"
(Y page 51). 42
Occupant safetySafety

tional restraint system. The seat belt cannot
perform its intended protective function if it is not fastened correctly. Also, an improperly
fastened seat belt can cause additional inju-
ries in the event of an accident, sudden brak-
ing or abrupt changes of direction. There is an increased risk of injury, possibly even fatal.
Secure persons less than 1.50 mtall in a suit-
able restraint system.
If you are travelling with a child younger than
12 years of age and under 1.50 m tall in the
vehicle:
R always secure the child in a child restraint
system suitable for this Mercedes-Benz
vehicle. The child restraint system must be
appropriate to the age, weight and size of
the child.
R ensure that you observe the instructions
and safety notes on "Children in the vehi-
cle" in these Operating Instructions
(Y page 55) in addition to the child
restraint system manufacturer's instruc-
tions G
WARNING
Seat belts cannot protect as intended, if:
R they are damaged, have been modified, are
extremely dirty, bleached or dyed
R the seat belt buckle is damaged or
extremely dirty
R modifications have been made to the belt
tensioners, belt anchorages or inertia reels
Damage caused to safety belts in an accident may not be visible, e.g. by splinters of glass.
Modified or damaged seat belts can tear or
fail, for example in the event of an accident.
Modified seat belt tensioners may be
deployed unintentionally or fail to be deployed
when required. There is an increased risk of
injury, possibly even fatal.
Never modify safety belts, seat belt tension-
ers, seat belt anchorages and inertia reels.
Ensure that seat belts are not damaged or
worn and are clean. After an accident, have the seat belts checked immediately at a quali-
fied specialist workshop.
Mercedes-Benz recommends that you only
use seat belts which have been approved
specifically for your vehicle by Mercedes-
Benz.
Correct seat belt use Observe the safety notes on the seat belt
(Y
page 44).
All vehicle occupants must be wearing the
seat belt correctly before beginning the jour- ney. Also make sure that all vehicle occu-
pants are always wearing the seat belt cor-
rectly while the vehicle is in motion.
When fastening the seat belt, always make
sure that:
R the seat belt tongue is only inserted to the
belt buckle belonging to that seat.
R the seat belt is tight across your body.
Avoid wearing bulky clothing, e.g. a winter
coat.
R the seat belt is not twisted.
Only then can forces which occur be dis-
tributed across the surface of the seat belt.
R the shoulder section of the belt is always
routed across the centre of your shoulder.
The shoulder section of the seat belt should
not touch your neck nor be routed under
your arm. If possible, adjust the seat belt to the appropriate height.
R the lap belt passes across your lap as
tightly and as low down as possible.
The lap must always be routed across your
hip joints and never across your abdomen.This applies particularly to pregnant
women. If necessary, press the lap belt
down into your hip joints and pull tight withthe shoulder section of the belt.
R the seat belt is not routed across sharp,
pointed or fragile objects.
If you have such items located on or in your
clothing, e.g. pens, keys or spectacles,
store these in a suitable place. Occupant safety
