PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lamp:and
PASSENGER AIR BAG OFF indicator lamp ;are
part of the Occupant Classification System
(OCS).
The indicator lamps display the status of the
front-passenger front air bag.
RPASSENGER AIR BAG ON lights up: the front-
passenger front air bag is enabled. If, in the
event of an accident, all deployment criteria
are met, the front-passenger front air bag is
deployed.
RPASSENGER AIR BAG OFF lights up: the front-
passenger front air bag is deactivated. It will
then not be deployed in the event of an acci-
dent.
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 53) and on "Chil-
dren in the vehicle" (Ypage 61). 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 53). Be sure to
observe the notes on "Seat
belts“ (
Ypage 46) and "Air bags"
(Ypage 50). 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 for the front seat belts
and the outer seat belts in the rear
RBelt bags for the outer seat belts in the rear,
depending on the vehicle's equipment
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 seats 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.
46Occupant safety
Safety 

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 47).
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.
RThe seat belt is not routed over sharp, pointed
or fragile objects.
If these item s a
re 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 the
seat 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 325).
Rear beltbags
iObserve the "Important safety notes" sec-
tion (Ypage 50).
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 belt bag may damage a
non-approved child restraint system. 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, a child restraint system with
an integrated seat belt should always be
installed using LATCH-type (ISOFIX). In a vehi- cle with optional belt bags for the rear seats,
you should only ever use a booster seat with
integrated backrest that has been tested and
approved by Mercedes-Benz in conjunction
with a belt bag. Never use a seat belt equipped
with a belt bag to secure a forward or rear-
ward-facing child restraint system or a boos-
ter seat that has not been approved. For infor-
mation on approved child restraint systems,
48Occupant safety

please contact an authorized Mercedes-BenzCenter.
Further information on child restraint systems
(
Ypage 61).
When triggered, belt bags :open, increasing
the protected area of the occupants' ribcages.
The belt bags 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 47) and the notes on correct use of seat
belts (Ypage 48).
Basic illustration
XAdjust the seat (Ypage 104).
The seat backrest must be in an almost ver-
tical position.
XPull the seat belt smoothly from the belt out- let.
The seat belt on the driver’s seat and the
front-passenger seat may be tightened auto-
matically, see "Belt adjustment"
(
Ypage 50).
XIf necessary, pull upwards on the shoulder
section of the seat belt to tighten the belt
across your body.
The shoulder section of the seat belt must
always be routed across the center of the shoul-
der. Adjust the belt outlet if necessary.
XTo raise: slide the belt outlet upwards.
The belt outlet will engage in various posi-
tions.
XTo lower: hold belt outlet release =and slide
belt outlet downwards.
XLet go of belt outlet release =in the desired
position and make sure that the belt outlet

All seat belts except the driver's seat belt are
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 62).
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.
