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.
Furthermore, the restraint system may also reduce the forces exerted on the vehicle occu-
pants when an accident occurs.
The restraint system includes:
RSeat belt system
RAir bags
RChild restraint system
RChild seat securing system
The components of the restraint system work in
conjunction with each other. They can only offer
the intended level of protection if all vehicle
occupants:
Rare correctly wearing their seat belts.
(Ypage 47)
Radjust their seat and head restraint properly
(Ypage 101).
The driver is also responsible for ensuring that
the steering wheel has been correctly posi-
tioned. Observe the information relating to the
correct driver's seat position (
Ypage 100).
Always ensure the air bag can inflate properly if
deployed (
Ypage 49).
An air bag supplements a correctly fastened
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 the protection already provided by a cor-
rectly fastened seat belt will suffice, the air bags
are not deployed. Furthermore, only the air bags that would increase the degree of protection
afforded to the vehicle occupants in the event of
an accident are deployed. 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 Emergency Ten-
sioning Devices and air bags" (
Ypage 56).
See “Children in the vehicle” for information on
children traveling with you as well as vehicle
restraint systems (
Ypage 60).
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.
44Occupant safety
Safety
Depending on the person in the front-passenger
seat, the front-passenger front air bag must
either be deactivated or enabled; see the fol-
lowing points. You must make sure of this both
before and during a journey.
RChildren in a child restraint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the instal-led child restraint system, and the age and
size of the child. Therefore, be sure to observe
the notes on the "Occupant Classification
System (OCS)" (
Ypage 52) and on "Chil-
dren in the vehicle" (Ypage 60). There you
will also find instructions on rearward and
forward-facing child restraint systems on the
front-passenger seat.
RAll other persons: depending on the classi-
fication of the person in the front-passenger
seat, the front-passenger front air bag is ena-
bled or deactivated (
Ypage 52). Be sure to
observe the notes on "Seat
belts“ (
Ypage 46) and "Air bags"
(Ypage 49). There you can also find infor-
mation on the correct seat position.
Seat belts
Introduction
Seat belts are the most effective means of
restricting the movement of vehicle occupants
in the event of an accident or the vehicle rolling over. This reduces the risk of vehicle occupants
coming into contact with parts of the vehicle
interior or being ejected from the vehicle. Fur-
thermore, the seat belt helps to keep the vehicle
occupant in the best position in relation to the
air bag.
The seat belt system comprises:
RSeat belts
REmergency Tensioning Devices for the front
seat belts and the outer seat belts in the rear
RSeat belt force limiters
If the seat belt is pulled out of the belt outlet
quickly or with a jerky movement, the belt
retractor locks. The belt strap cannot be extrac-
ted any further.
The Emergency Tensioning Device tightens the
seat belt in an accident, pulling the belt close
against the body. However it does not pull the
vehicle occupant back in the direction of the
backrest. The Emergency Tensioning Device does not cor-
rect an incorrect seat position or the routing of
an incorrectly fastened seat belt.
When triggered, a seat belt force limiter helps to
reduce the force exerted by the seat belt on the
vehicle occupant.
The seat belt force limiters for the
front s
eats are
synchronized with the front air bags, which
absorb part of the deceleration force. This can
reduce the force exerted on the vehicle occu-
pants during an accident.
!If the front-passenger seat is unoccupied,
do not insert the belt tongue into the buckle of
the front-passenger seat. This may otherwise
lead to the triggering of the Emergency Ten-
sioning Device in the event of an accident,
which will then need to be replaced.
Important safety notes
The use of seat belts and child restraint systems
is required by law in:
Rall 50 states
Rthe U.S. territories
Rthe District of Columbia
Rall Canadian provinces
Even where this is not required by law, all vehicle
occupants should correctly fasten their seat
belts before starting the journey.
GWARNING
If the seat belt is incorrectly fastened, it can-
not protect as intended. Furthermore, an
incorrectly fastened seat belt can cause addi-
tional injury, for example, in an accident, dur-
ing braking or when abruptly changing direc-
tion. This poses an increased risk of injury or
even fatal injury.
Make sure that all vehicle occupants are
seated properly with a correctly fastened seat belt.
GWARNING
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
46Occupant safety
Safety
poses an increased risk of injury or even fatalinjury.
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.
GWARNING
Persons under 5 ft (1.50 m) in height cannot
fasten the seat belt correctly without an addi- tional suitable restraint system. If the seat
belt is incorrectly fastened, it cannot protect
as intended. Furthermore, an incorrectly fas-
tened seat belt can cause additional injury, for
example, in an accident, during braking or an
abrupt change of direction. This poses an
increased risk of injury or even fatal injury.
For this reason, always secure persons under
5 ft (1.50 m) in height in suitable 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 "Children in the vehicle"
(
Ypage 60) 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 52)
GWARNING
The seat belts may not perform their intended protective function if:
Rthey are damaged, modified, extremely
dirty, bleach 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 sustain non-visible damage inan 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.
Proper use of the seat belts
Pay attention to the safety notes about the seat
belt (Ypage 46).
All vehicle occupants must fasten the seat belt
correctly before setting off. Make sure that all
occupants are wearing their seat belts correctly
for the entire journey.
When fastening the seat belt, make sure that:
RThe seat belt tongue is inserted into the belt
buckle that belongs to the seat.
RThe seat belt is tightened across your body.
Avoid wearing bulky clothing, e.g. a winter
coat.
RThe seat belt is not twisted.
Only then can the forces produced in the
event of an accident be evenly distributed
across the belt.
RThe shoulder section of the belt must always
be routed across the center of the shoulder.
The shoulder section of the belt should not
come into contact with your neck and must
not be routed under the arm. Where possible,
adjust the seat belt to the appropriate height.
RThe lap belt must be taut and as low as pos-
sible over your lap.
The lap belt must always pass across your hip
joints and never across your stomach or
abdomen. Pregnant women must take partic-
ular care. If necessary, the lap belt can be
pushed down across the hip joints and pulled
tight using the shoulder section.
Occupant safety47
Safety
Z
RThe seat belt is not routed over sharp, pointed
or fragile objects.
If these items are on or in your clothing, e.g.
eyeglasses, pens, keys, etc., stow these items
in a more suitable location.
ROnly one person should use each seat belt at
any one time.
On no account should babies or children
travel sitting on the lap of another vehicle
occupant. During an accident, they could be
crushed between the occupant and seat belt.
RObjects are not secured with a seat belt if theseat belt is being used by one of the vehicle’s
occupants.
Also make sure that there are no objects, e.g.
cushions, between the occupant and the seat.
Seat belts are solely intended for the protection
and restraint of the vehicle occupants. To
secure objects, luggage or loads, always
observe the "Loading guidelines" (
Ypage 329).
Fastening and adjusting the seat belts
Observe the safety notes on the seat belt
(Ypage 46) and the notes on correct use of seat
belts (Ypage 47).

securely fasten child restraint systems in the
vehicle. Further information can be found under
"Special seat belt retractor" (
Ypage 60).
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.
48Occupant safety
Safety
If a child is traveling in your vehicle, also
observe the following notes:
RAlways secure children under twelve years of
age and less than 5 ft (1.50m)tall in suitable
child restraint systems.
RChild restraint systems should be installed on
the rear seats.
ROnly secure a child in a rearward-facing child restraint system on the front-passenger seat
when the front-passenger front air bag is
deactivated. If the PASSENGER AIR BAG OFF
indicator lamp is permanently lit, the front-
passenger front air bag is deactivated
(
Ypage 45).
RAlways observe the instructions and safety
notes on the "Occupant Classification System
(OCS)" (
Ypage 52) and on "Children in the
vehicle" (Ypage 60) in addition to the child
restraint system manufacturer's installation
and operating instructions.
Objects in the vehicle interior may prevent
an air bag from functioning correctly. Before
starting your journey and to avoid risks resulting
from the speed of the air bag as it deploys, make sure that:
Rthere are no people, animals or objects
between the vehicle occupants and an air
bag.
Rthere are no objects between the seat, door
and B-pillar.
Rno hard objects, e.g. coat hangers, hang on
the grab handles or coat hooks.
Rno accessories, such as cup holders, are
attached to the vehicle within the deployment area of an air bag, e.g. to doors, side windows,
rear side trim or side walls.
Rno heavy, sharp-edged or fragile objects are in
the pockets of your clothing. Store such
objects in a suitable place.
GWARNING
If you modify the air bag cover or affix objects
such as stickers to it, the air bag can no longer
function correctly. There is an increased risk
of injury.
Never modify an air bag cover or affix objects
to it.
GWARNING
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 pan-
eling carried out at a qualified specialist work-
shop.
Front air bags
Driver's air bag :deploys in front of the steer-
ing wheel. Front-passenger front air bag ;
deploys in front of and above the glove box.
When deployed, the front air bags offer addi-
tional head and thorax protection for the occu-
pants in the front seats.
The PASSENGER AIR BAG OFF and PASSENGER AIR BAG ON indicator lamps inform you about
the status of the front-passenger air bag
(
Ypage 45).
The front-passenger front air bag will only
deploy if:
Rthe system, based on the OCS weight sensor
readings, detects that the front-passenger
seat is occupied (
Ypage 52). The
PASSENGER AIR BAG ON indicator lamp is lit
(
Ypage 52)
Rthe restraint system control unit predicts a
