Occupant safety
Introduction to the restraint system
The restraint system can reduce the risk of vehi- cle occupants coming into contact with parts of
the vehicle's interior in the event of an accident.
The restraint system can also reduce the forces to which vehicle occupants are subjected during
an accident.
The restraint system comprises:
Rseat belt system
Rair bags
Rchild restraint system
Rchild seat securing systems
The components of the restraint system work in
conjunction with each other. They can only
deploy their protective function if, at all times, all vehicle occupants:
Rhave fastened their seat belts correctly
(Ypage 45)
Rhave adjusted their seat and head restraint
properly (Ypage 100). As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the correct
driver's seat position (
Ypage 100).
You also have to make sure that an air bag can
inflate properly if deployed (
Ypage 48).
An air bag supplements a correctly worn seat
belt. As an additional safety device, the air bag
increases the level of protection for vehicle
occupants in the event of an accident. For exam-
ple, if, in the event of an accident, the protection
offered by the seat belt is sufficient, the air bags are not deployed. When an accident occurs, only
the air bags that increase protection in that par-ticular accident situation are deployed. How-
ever, seat belts and air bags generally do not
protect against objects penetrating the vehicle
from the outside.
Information on restraint system operation can
be found under "Triggering of the Emergency
Tensioning Devices and air bags" (
Ypage 55).
For information on children traveling with you in
the vehicle and on child restraint systems, see
"Children in the vehicle" (
Ypage 59).
Important safety notes
GWARNING
Modifications to the restraint system may
cause it to no longer work as intended. The
restraint system may then not perform its
intended protective function and may fail in an
accident or trigger unexpectedly, for example.
This poses an increased risk of injury or even fatal injury.
Never modify parts of the restraint system.
Never tamper with the wiring, the electronic
components or their software.
If it is necessary to modify components of the
restraint system to accommodate a person
with disabilities, contact an authorized
Mercedes-Benz Center for details. USA only:
for further information contact our Customer
Assistance Center at 1-800-FOR-MERCedes
(1‑800‑367‑6372).
Mercedes-Benz recommends that you only use
driving aids which have been approved specifi-
cally for your vehicle by Mercedes-Benz.
42Occupant safety
Safety

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 injuryor 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:
Ralways secure the child in a child restraint
system suitable for this Mercedes-Benz vehi-
cle. The child restraint system must be appro-
priate to the age, weight and size of the child
Ralways observe the instructions and safety
notes on the belt bags for the outer seat belts
in the rear (
Ypage 46)
Ralways observe the instructions and safety
notes on "Children in the vehicle"
(
Ypage 59) in addition to the child restraint
system manufacturer's installation and oper-
ating instructions
Rbe sure to observe the instructions and safety
notes on the "Occupant classification system
(OCS)" (
Ypage 51)
GWARNING
The seat belts may not perform their intended protective function if:
Rthey are damaged, modified, extremely
dirty, bleached or dyed
Rthe seat belt buckle is damaged or
extremely dirty
Rthe Emergency Tensioning Devices, belt
anchorages or inertia reels have been modi-
fied.
Seat belts may be damaged in an accident,
although the damage may not be visible, e.g.
due to splinters of glass. Modified or damaged
seat belts may tear or fail, e.g. in an accident.
Modified Emergency Tensioning 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 and 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.
Proper use of the seat belts
Observe the safety notes on the seat belt
(Ypage 44).
All vehicle occupants must be wearing the seat
belt correctly before beginning the journey. Also
make sure that all vehicle occupants are always
wearing the seat belt correctly while the vehicle
is in motion.
When fastening the seat belt, always make sure
that:
Rthe seat belt tongue is only inserted to the belt
buckle belonging to that seat.
Rthe seat belt is tight across your body.
Avoid wearing bulky clothing, e.g. a winter
coat.
Rthe seat belt is not twisted.
Only then can the forces which occur be dis-
tributed over the area of the belt.
Rthe shoulder section of the belt is always
routed across the center of your shoulder.
The shoulder section of the belt must not
come into contact with your neck or be routed
under your arm. Where possible, adjust the
seat belt to the appropriate height.
Rthe lap belt passes tightly and as low down as possible across your lap.
The lap belt must always be routed across
your hip joints and not across your abdomen.
This applies particularly to pregnant women.
If necessary, push the lap belt down to your
hip joint and pull it tight using the shoulder
section of the belt.
Rthe seat belt is not routed across sharp, poin-
ted or fragile objects.
If you have such items located on or in your
clothing, e.g. pens, keys or eyeglasses, store
these in a suitable place.
Ronly one person is using a seat belt at a time.
Infants and children must never travel sitting
on the lap of a vehicle occupant. In the event
Occupant safety45
Safety
Z

of an accident, they could be crushed
between the vehicle occupant and seat belt.
Robjects are never secured with a seat belt if
the seat belt is also being used by one of the
vehicle's occupants.
Also ensure that there are never objects
between a person and the seat, e.g. cushions.
Seat belts are only intended to secure and
restrain vehicle occupants. Always observe the
"Loading guidelines" for securing objects, lug-
gage or loads (
Ypage 281).
Rear beltbags
iObserve the "Important safety notes" sec-
tion (Ypage 48).
Depending on the vehicle's equipment, the
outer rear seat belts are equipped with a belt
bag. This can be seen from the BELTBAG iden-
tification on the rear seat belt.
GWARNING
In an accident, the beltbag may damage a
child restraint system that is not permitted or
that has not been approved for a beltbag. As a result, the child restraint system may not be
able to provide the intended level of protec-
tion. This poses an increased risk of injury or
even fatal injury.
For this reason, always secure a child
restraint system with an integrated seat belt
with LATCH-type (ISOFIX). On vehicles with
optional beltbags for the rear seats, only use a
booster seat with an integrated backrest,
which has been tested and approved by
Mercedes-Benz in combination with a belt-
bag. Never use a seat belt equipped with a
beltbag to secure a forward or rearward-
facing child restraint system or a non-
approved booster seat. Contact an authorized
Mercedes-Benz Center for information on
approved child restraint systems.
Further information on child restraint systems
(
Ypage 59).
When triggered, belt bags :open, increasing
the protected area of the occupants' ribcages.
The beltbags are triggered depending on the
type and severity of the accident.
Fastening and adjusting the seat belts
Observe the safety notes on the seat belt
(Ypage 44) and the notes on correct use of seat
belts (Ypage 45).

equipped with a special seat belt retractor to
securely fasten child restraint systems in the
vehicle. Further information can be found under
"Special seat belt retractor" (
Ypage 59).
Rear seat belt buckle extenders
The seat belt extender is an integral part of the
PRE-SAFE®convenience function. It is used on
the outer rear seats.
Always ensure that it is possible to move the belt
buckle freely. Always stow objects in the vehicle
correctly.
To assist you in finding the seat belt buckle and
fastening the seat belt:
Rthe belt buckle moves forwards to a conven-
ient position
Rthe belt buckle is illuminated
After the seat belt is fastened, the belt buckle
returns to its normal position. The seat belt then
lies tight across the lap and thorax areas.
Incorporation into the PRE-SAFE
®system:
the belt buckle is lowered quickly in certain haz-
ardous situations. This pre-tensions the seat
belt.
Incorporation into the automatic measures
after the accident: in this situation, the belt
buckle is illuminated and extended after a rear
door is opened.
Releasing seat belts
!Make sure that the seat belt is fully rolled up.
Otherwise, the seat belt or belt tongue will be
trapped in the door or in the seat mechanism.
This could damage the door, the door trim
panel and the seat belt. Damaged seat belts
can no longer fulfill their protective function
and must be replaced. Visit a qualified spe-
cialist workshop.
XPress the release button in the belt buckle,
hold the belt tongue firmly and guide the belt
back.
Seat belt adjustment
The seat-belt adjustment is an integral part of
the PRE-SAFE®convenience function. This func-
tion adjusts the driver's and front-passenger
seat belt to the upper body of the occupants.
The belt strap is tightened slightly when:
Rthe belt tongue is engaged in the buckle and
Rthe ignition is switched on
The seat-belt adjustment will apply a certain
retraction force if any slack is detected between
the vehicle occupant and the seat belt. Do not
hold on to the seat belt tightly while it is adjust-
ing.
You can activate and deactivate the seat-belt
adjustment function using the multimedia sys-
tem. Information on activating and deactivating
the seat-belt adjustment function can be found
in the Digital Operator's Manual.
Belt warning for the driver and front
passenger
The 7 seat belt warning lamp in the instru-
ment cluster is a reminder that all vehicle occu- pants must wear their seat belts. It may light up
continuously or flash. In addition, there may be
a warning tone.
Regardless of whether the driver's seat belt has
already been fastened, the 7seat belt warn-
ing lamp lights up for six seconds each time the engine is started. If, after six seconds, the driver
or front-passenger seat belt has not been fas-
tened and the doors are closed, the 7seat
belt warning lamp lights up. As soon as the driv-
er's and front-passenger seat belts are fastened
or a front door is opened again, the 7seat
belt warning lamp goes out.
If the driver's seat belt is not fastened after the
engine is started, an additional warning tone will
sound. The warning tone switches off after six
seconds or once the driver's seat belt is fas-
tened.
If the vehicle's speed exceeds 15 mph
(25 km/h) once and the driver's and front-
passenger seat belts are not fastened, a warning
tone sounds. A warning tone also sounds with
increasing intensity for 60 seconds or until the
