For safety reasons, Mercedes-Benz recom-
mends that you only use seat accessories
that have been approved by Mercedes-Benz.
Both the driver and the front passenger
should always observe the PASSENGER AIR
BAG OFF indicator lamp as an indication of
whether or not the front passenger is posi-
tioned correctly. Observe also the air bag dis- play messages that can be displayed in the
instrument cluster (Y page 242).G
WARNING
If the 00730074 indicator lamp illuminates
when an adult or someone larger than a small individual is in the front-passenger seat, havethe front passenger reposition himself or her-
self in the seat until the 00730074indicator
lamp goes out.
In the event of a collision, the air bag control
unit will not allow front-passenger front air
bag deployment when the OCS has classified
the front-passenger seat occupant as weigh-
ing as much as or less than a typical 12-
month-old child in a standard child restraint or if the front-passenger seat is classified as
being empty.
When the OCS senses that the front-
passenger seat occupant is classified as
being up to or less than the weight of a typical
12-month-old child in a standard child
restraint, the 00730074indicator lamp will
illuminate when the engine is started and
remain illuminated, indicating that the front-
passenger front air bag is deactivated.
When the OCS senses that the front-
passenger seat is classified as being empty,
the 00730074 indicator lamp will illuminate
when the engine is started and remain illumi-
nated, indicating that the front-passenger
front air bag is deactivated.
When the OCS senses that the front-
passenger seat occupant is classified as
being heavier than the weight of a typical 12-
month-old child seated in a standard child
restraint or as being a small individual (such
as a young teenager or a small adult), the
00730074 indicator lamp will illuminate for approximately 6 seconds when the engine is
started and then, depending on occupant
weight sensor readings from the front-
passenger seat, remain illuminated or go out. With the 00730074 indicator lamp illumina-
ted, the front-passenger front air bag is deac-
tivated. With the 00730074indicator lamp
out, the front-passenger front air bag is acti-
vated.
When the OCS senses that the front-
passenger seat occupant is classified as an
adult or someone larger than a small individ-
ual, the 00730074 indicator lamp will illumi-
nate for approximately 6 seconds when the
engine is started and then go out, indicating
that the front-passenger front air bag is acti-
vated.
If the 00730074 indicator lamp is illuminated,
the front-passenger front air bag is deactiva-
ted and will not be deployed.
If the 00730074 indicator lamp is not illumi-
nated, the front-passenger front air bag is
activated and will be deployed:
R in the event of certain frontal impacts
R if impact exceeds a preset deployment
threshold
R independently of the side impact air bags
If the front-passenger front air bag is
deployed, the rate of inflation will be influ-
enced by:
R the rate of relevant vehicle deceleration as
assessed by the air bag control unit
R the front passenger's weight category as
identified by OCS G
WARNING
According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus, we strongly recommend that children be
placed in the rear seats whenever possible.
Regardless of seating position, children 12
years old and under must be seated and prop- erly secured in an appropriate infant restraint, 50

If you do so, the head restraints cannot fulfill
their intended protective function in the event of an accident. In addition, objects attached
to the head restraints could endanger other
vehicle occupants. There is an increased risk
of injury.
Do not attach any objects to the head
restraints and do not use head restraint cov-
ers.
NECK-PRO head restraints/NECK-PRO luxury
head restraints increase protection of the
driver's and front-passenger's head and
neck. In the 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.
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 seat and the front-passenger
seat (Y page 55). Otherwise, the additional
protection will not be available in the event of
another rear-end collision. You can see that a
NECK-PRO head restraint/NECK-PRO luxury
head restraint has been triggered if it is tilted forward and can no longer be adjusted.
Mercedes-Benz recommends that you have
the NECK-PRO head restraints/NECK-PRO
luxury head restraints checked at a qualified
specialist workshop after a rear-end collision. Resetting a triggered NECK-PRO head

Important safety notes The use of seat belts and child restraint sys-
tems is required by law in:
R all 50 states
R the U.S. territories
R the District of Columbia
R all Canadian provinces
Even where this is not required by law, all
vehicle occupants should correctly fasten
their seat belts before starting the journey. i
See "Children in the vehicle"
(Y page 61) for further information on
infants and children traveling in the vehicle
as well as on child restraint systems. G
WARNING
The seat belt does not offer the intended level of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
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
The seat belts may not perform their intended protective function if:
R they are damaged, modified, extremely
dirty, bleach or dyed
R the seat belt buckle is damaged or
extremely dirty
R the Emergency Tensioning Devices, belt
anchorages or inertia reels have been modi-
fied
Seat belts may sustain non-visible damage in an accident, e.g. due to glass splinters. Modi-
fied or damaged seat belts may tear or fail,
e.g. in an accident. Modified Emergency Ten-
sioning Devices could accidentally trigger or
fail to deploy when necessary. This poses an
increased risk of injury or even fatal injury.
Never modify the seat belts, Emergency Ten-
sioning Devices, belt anchorages or inertia
reels. Make sure that the seat belts are
undamaged, not worn out and clean. Follow-
ing an accident, have the seat belts checked
immediately at a qualified specialist work-
shop.
Only use seat belts that have been approved
for your vehicle by Mercedes-Benz. Any such 56

Proper use of the seat belts G
WARNING
USE SEAT BELTS PROPERLY
R Seat belts can only work when used prop-
erly. Never wear seat belts in any other way
than as described in this section, as that
could result in serious injuries in the event
of an accident.
R Each occupant should wear their seat belt
at all times, because seat belts help reduce the likelihood of and potential severity of
injuries in accidents, including rollovers.
The integrated restraint system includes
SRS (driver front air bag, driver's side knee
bag, front-passenger front air bag, side
impact air bags, pelvis air bags, window
curtain air bags for the side windows),
Emergency Tensioning Devices, seat belt
force limiters, and front seat knee bolsters.
The system is designed to enhance the pro-
tection offered to properly belted occu-
pants in certain frontal (front air bags, driv-
er's side knee bag and ETDs) and side (side
impact air bags, window curtain air bags,
and ETDs) impacts which exceed preset
deployment thresholds and in certain roll-
overs (window curtain air bags and ETDs). R
Never wear the shoulder belt under your
arm, across your neck or off your shoulder.
In a frontal crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The seat belt would also apply too much force to the
ribs or abdomen, which could severely
injure internal organs such as your liver or
spleen.
Adjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder. It should not
touch the neck. Never pass the shoulder
portion of the seat belt under your arm. For
this purpose, you can adjust the height of
the seat belt outlet.
R Position the lap belt as low as possible on
your hips and not across the abdomen. If
the lap belt is positioned across your abdo-
men, it could cause serious injuries in a
crash.
R Never wear seat belts over rigid or breaka-
ble objects in or on your clothing, such as
eyeglasses, pens, keys etc., as these might cause injuries.
R Make sure the seat belt is always fitted
snugly. Take special care of this when wear-
ing loose clothing.
R Never use a seat belt for more than one
person at a time. Do not fasten a seat belt
around a person and another person or
other objects at the same time.
R Seat belts should not be worn twisted. In a
crash, you would not have the full width of
the seat belt to distribute impact forces.
The twisted seat belt against your body
could cause injuries.
R Pregnant women should also always use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible on
the hips to avoid any possible pressure on
the abdomen.
R Place the seat backrest in a position that is
as upright as possible.
R Check your seat belt during travel to make
sure it is properly positioned. Occupant safety
