vehicle. This also includes labeling and docu-
mentation affected by their modifications.
It is their responsibility to certify that:
R the altered vehicle conforms to all applica-
ble standards and regulations affected by
the vehicle alteration
R the altered vehicle continues to comply with
the motor vehicle safety standards and
emissions regulations
R the changes or installation of accessories do
not impair the safety of the vehicle
We are not responsible for any final certifica-
tion or claims regarding product liability or
warranty claims that arise as a result of such
changes. This applies to:
R components, assemblies or systems which
have been altered
R non-compliance with emissions laws and
regulations or with vehicle safety standards
arising as a result of the alterations
R all consequences resulting form the
changed, less safe or even defective vehicle
We do not assume responsibility as the final
stage manufacturer or the consequential prod-
uct liability.
Notes on the engine radiator Even seemingly small changes to the vehicle,
such as attaching a radiator trim for winter
driving or as protection against insects, are
not permitted. Do not cover the radiator. Do
not use thermal mats, insect protection covers
or anything similar.
Doing so can cause the diagnostics system to
display inaccurate values. Some of these val-
ues are legally required and must always be
correct.
Notes for commercial vehicles without
partitions Vehicles, which are approved as commercial
vehicles (N1), do not comply with the
ISO 27956
standard in the respective current
valid version unless equipped with a partition.
The ISO 27956 Standard details the equip-
ment for correct load securing in delivery vehi-
cles. Retrofitting the partition is strongly rec-
ommended when using the vehicle for the
transport of goods, as correct load securing in
vehicles without the partition is difficult to
achieve. Genuine Mercedes-Benz parts
! Air bags and Emergency Tensioning Devi-
ces, as well as control units and sensors for
these restraint systems, may be installed in
the following areas of your vehicle:
R doors
R door pillars
R door sills
R seats
R cockpit
R instrument cluster
R center console
Do not install accessories such as audio sys-
tems in these areas. Do not carry out
repairs or welding. You could impair the
operating efficiency of the restraint sys-
tems.
Have aftermarket accessories installed at a
qualified specialist workshop. H
Environmental note
We supply reconditioned assemblies and
parts which are of the same quality as new
parts. The same New Vehicle Limited War-
ranty applies as for new parts.
The operating safety of the vehicle could be
jeopardized if you use parts, tires and wheels
as well as accessories relevant to safety which
have not been approved by Mercedes-Benz.
This could lead to malfunctions in safety-rele-
vant systems, e.g. the brake system. Only use
genuine Mercedes-Benz parts or parts of equal
quality. Only use tires, wheels and accessories
that have been specifically approved for your
vehicle.
Mercedes-Benz tests genuine Mercedes-Benz
parts, conversion parts and accessories that
have been specifically approved for the type of
vehicle for:
R Reliability
R Safety
R Suitability
Despite ongoing market research, Mercedes-
Benz is unable to assess other parts. Even if
an independent or official approval has been
provided in exceptional cases, Mercedes-Benz
accepts no responsibility for the use of such
parts in Mercedes-Benz vehicles. 34
Introduction

back in the direction of the seat backrest,
however.
In addition, the Emergency Tensioning Device
cannot compensate for the seat position being
incorrect or for an incorrectly worn seat belt.
When triggered, seat belt force limiters help to
reduce the peak force exerted by the seat belt
on the vehicle occupant.
The belt force limiters on the front seats are
synchronized with the front air bags, which
take on a part of the deceleration force. This
helps to reduce the forces to which vehicle
occupants are subjected during an accident.
! If the front-passenger seat is not occupied,
do not engage the seat belt tongue in the
buckle on the front-passenger seat. Other-
wise, in addition to other systems, the Emer-
gency Tensioning Device could also be trig-
gered in the event of an accident and would
need to be replaced.
Important safety notes The use of seat belts and child restraint sys-
tems is required by law in:
R all 50 states
R the US territories
R the District of Columbia
R all Canadian provinces
Even where this is not required by law, all vehi-
cle occupants should correctly fasten their
seat belts before starting the journey. G
WARNING
If the seat belt is not worn correctly, it can-
not perform its intended protective function.
An incorrectly fastened seat belt can also
cause injuries, for example, in the event of
an accident or when braking or changing
direction abruptly. This poses an increased
risk of injury or even fatal injury.
Always ensure that all vehicle occupants
have their seat belts fastened correctly and
are sitting properly. The various components of the restraint sys-
tem work complementary to one another. They
can only perform their intended protective
function if all vehicle occupants:
R have correctly fastened their seat belt
(Y page
49)
R have correctly adjusted their seat and head
restraint ( Y page 87) G
WARNING
The seat belt does not offer the intended
level of protection if you have not moved the
backrest to an almost vertical position.
When braking or in the event of an accident,
you could slide underneath the seat belt and
sustain abdomen or neck injuries, for exam-
ple. This poses an increased risk of injury or
even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the back-
rest is in an almost vertical position and that
the shoulder section of your seat belt is
routed across the center of your shoulder. G
WARNING
Persons less than 5 ft (1.50 m) tall cannot
wear the seat belt correctly without an addi-
tional and suitable restraint system. If the
seat belt is not worn correctly, it cannot per-
form its intended protective function. An
incorrectly fastened seat belt can also cause
injuries, for example, in the event of an acci-
dent or when braking or changing direction
abruptly. This poses an increased risk of
injury or even fatal injury.
For this reason, always secure persons
under 5 ft

(1.50 m) tall in suitable additional
restraint systems.
If a child younger than twelve years old and
under 5 ft (1.50 m) in height is traveling 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 in the "Children in the vehi- 48
Occupant safety
Safety

Air bags
Introduction The installation point of an airbag can be rec-
ognized by the AIRBAG marking.
An airbag complements the correctly fastened
seat belt. It is no substitute for the seat belt.
When deployed, an airbag can increase the
protection provided for the respective vehicle
occupant.
Not all airbags are deployed in an accident.
The various airbags work independently of
each other (Y page
58).
However, no system available today can com-
pletely eliminate injuries and fatalities.
It is also not possible to rule out a risk of injury
caused by an airbag due to the high speed at
which the airbag must be deployed.
Important safety notes G
WARNING
If the front passenger air bag has been acti-
vated, a child on the front passenger seat
may be hit by the front passenger air bag in
the event of an accident. There is a risk of
injury or fatal injury.
NEVER use a rearward-facing child restraint
system on a seat protected by an ACTIVE
FRONT AIRBAG; DEATH or SERIOUS INJURY
to the CHILD can occur.
When installing a child restraint system on the
front-passenger seat observe the vehicle-spe-
cific notes

(Y page 64). You must observe
the notes on rearward and forward-facing child
restraint systems on the front-passenger seat. G
WARNING
If you deviate from the correct seat position,
the air bag cannot perform its intended pro-
tective function and deployment may even
cause further injuries. This poses an
increased risk of injury or even fatal injury.
To avoid any risks, each vehicle occupant
must always make sure of the following:
R Fasten the seat belt correctly. In the case
of pregnant women in particular, make sure that the lap belt is never routed
across the stomach or abdomen.
R Adopt the correct seat position and keep
as far away as possible from the air bags.
R Observe the following notes.
Always make sure that there are no objects
between the air bag and vehicle occupant.
All vehicle occupants must observe the follow-
ing notes to avoid risks posed by the air bag
when it deploys.
R Adjust the seats properly before beginning
your journey. Always make sure that the
seat is in an almost upright position. The
center of the head restraint must support
the head at about eye level.
R Move the driver's and front-passenger seats
as far back as possible. The driver's seat
position must allow the vehicle to be driven
safely.
R Only hold the steering wheel on the outside.
This allows the air bag to be fully deployed.
R Always lean against the backrest while driv-
ing. Do not lean forward or lean against the
door or side window. You may otherwise be
in the deployment area of the air bags.
R Always keep your feet in the footwell in
front of the seat. Do not put your feet on the
dashboard, for example. Your feet may oth-
erwise be in the deployment area of the air
bag.
R For this reason, always secure persons less
than 5 ft

(1.50 m) tall in suitable restraint
systems. Up to this height, the seat belt
cannot be worn correctly.
If a child is traveling in your vehicle, also
observe the following notes:
R Always secure children under twelve years
of age and less than 5 ft (1.50 m) tall in suit-
able child restraint systems.
R Child restraint systems should preferably be
installed on the rear seats.
R Secure a child to the front-passenger seat
only when the front-passenger front air bag
is deactivated, and then only in a rearward-
facing child restraint system. The front-
passenger front air bag is deactivated when
the PASSENGER AIR BAG OFF indicator
lamp is lit continuously (Y page 47).
R Always observe the instructions and safety
notes on the "Occupant Classification Sys- Occupant safety
51
Safety Z

tem (OCS)" (Y page
54) and on "Children
in the vehicle" ( Y page 60) in addition to
the child restraint system manufacturer's
installation and operating instructions.
Objects in the vehicle interior may restrict
the air bag from functioning correctly. To
avoid risks resulting from the speed of the air
bag as it deploys, vehicle occupants must
ensure the following points.
Before commencing your journey, ensure that:
R there are no people, animals or objects
between the vehicle occupants and an air
bag
R there are no objects between the seat, door
and B-pillar
R there are no hard objects, e.g. coat hangers,
hanging on the grab handles or coat hooks
R no accessories, such as cup holders, are
attached to the vehicle within the deploy-
ment area of an air bag, e.g. to doors or side
windows
R no heavy, sharp-edged or fragile objects are
in the pockets of your clothing. Store such
objects in a suitable place G
WARNING
If you modify the cover of an air bag or affix
objects such as stickers to it, the air bag
can no longer perform its intended function.
There is an increased risk of injury.
Never modify the cover of an air bag or affix
objects to it.
Vehicles with window curtain air bags for
all seat rows: G
WARNING
Sensors to control the air bags are located
in the doors. Modifications or work not per-
formed correctly to the doors or door panel-
ing, as well as damaged doors, can lead to
the function of the sensors being impaired.
The air bags might therefore not function
properly anymore. Consequently, the air
bags cannot protect vehicle occupants as
they are designed to do. There is an
increased risk of injury.
Never modify the doors or parts of the
doors. Always have work on the doors or door paneling carried out at a qualified spe-
cialist workshop.
Front air bags !
Do not place heavy objects on the front-
passenger seat. This could cause the sys-
tem to identify the seat as being occupied.
In the event of an accident, the restraint
systems on the front-passenger side may be
triggered and have to be replaced. The driver's air bag
: deploys in front of the
steering wheel. The co-driver's air bag ;
deploys in front of and above the glove box
and center console.
When deployed, the front air bags offer addi-
tional head and thorax protection on the front
seats.
The PASSENGER AIR BAG OFF indicator lamp
informs you about the status of the co-driver's
air bag

(Y page 47).
The co-driver's air bag will deploy only if:
R the Occupant Classification System (OCS)
has detected that the co-driver's seat is
occupied ( Y page 54). The PASSENGER
AIR BAG OFF indicator lamp is not lit
( Y page 54)
R the restraint system control unit predicts a
high accident severity
Side impact air bags G
WARNING
Unsuitable seat covers can obstruct or pre-
vent deployment of the air bags integrated
into the seats. Consequently, the air bags
cannot protect vehicle occupants as they
are designed to do. In addition, the opera- 52
