Restraint system: introduction
The restraint system reduces 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:
R Seat belt system
R Air bags
R Child restraint system
R Child 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:
R have fastened their seat belts correctly
(Y page 53)
R have adjusted their seat and head restraint
properly (Y page 121).
As the driver, you also have to make sure that
the steering wheel is adjusted correctly.
Observe the information relating to the cor-
rect driver's seat position (Y page 120).
You also have to make sure that an air bag can inflate properly if deployed (Y page 56).
An air bag supplements a correctly worn seat
belt. As an additional safety device, the air
bag increases the level of protection for vehi-
cle occupants in the event of an accident. For example, if, in the event of an accident, the
protection offered by the seat belt is suffi-
cient, the air bags are not deployed. When an
accident occurs, only the air bags that
increase protection in that particular accident
situation are deployed. However, seat belts
and air bags generally do not protect against objects penetrating the vehicle from the out-
side.
Information on restraint system operation
can be found under "Deployment of Emer-
gency Tensioning Devices and air bags"
(Y page 65).
For more information about children traveling
with you in the vehicle and on child restraint
systems, see "Children in the vehicle"
(Y page 69). Important safety notes

WARNING
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. Occupant safety

ted. It will then not be deployed in the event
of an accident.
R PASSENGER 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.
Depending on the person in the front-
passenger seat, the front-passenger front air
bag must either be deactivated or enabled;
see the following points. You must make sure
of this both before and during a journey.
R Children in a child restraint system:
whether the front-passenger front air bag is
enabled or deactivated depends on the
installed child restraint system, and the age and size of the child. Therefore, be sure to
observe the notes on the "Occupant Clas-
sification System (OCS)" (Y page 59) and
on "Children in the vehicle" (Y page 69).
There you will also find instructions on rear-
ward and forward-facing child restraint sys- tems on the front-passenger seat.
R All other persons: depending on the clas-
sification of the person in the front-
passenger seat, the front-passenger front
air bag is enabled or deactivated
(Y page 59). Be sure to observe the notes
on "Seat belts“ (Y page 51) and "Air bags"
(Y page 56). 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 occu-
pants in the event of an accident or the vehi-
cle rolling over. This reduces the risk of vehi- cle occupants coming into contact with parts
of the vehicle interior or being ejected from
the vehicle. Furthermore, the seat belt helps
to keep the vehicle occupant in the best posi- tion in relation to the air bag. The seat belt system comprises:
R Seat belts
R Emergency Tensioning Devices for the
front seat belts and the outer seat belts in
the rear
R Seat belt force limiters for the front seat
belts and the outer seat belts in the rear
R Belt 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
extracted 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
correct an incorrect seat position or the rout-
ing of an incorrectly fastened seat belt.
When triggered, seat belt force limiters help
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 vehi-
cle occupants 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 oth-
erwise lead to the triggering of the Emer-
gency Tensioning 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 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 Occupant safety
51Safety Z

Even where this is not required by law, all
vehicle occupants should correctly fasten
their seat belts before starting the journey. G
WARNING
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. 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
Objects next to the front seat that block the
belt buckle or the moving belt anchorage on
the front seat impair the function of the Emer- gency Tensioning Devices. The Emergency
Tensioning Devices may not function as inten-
ded and the seat belt may no longer provide
the intended protection. This poses an
increased risk of injury or even fatal injury.
Before starting the journey, make sure that
there are no objects around the belt buckle or between the front seat and door. G
WARNING
Persons under 5 ft (1.50 m) in heightcannot
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 12 years 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 always observe the instructions and safety
notes on the belt bags for the outer seat
belts in the rear (Y page 53)
R always observe the instructions and safety
notes in the "Children in the vehicle" sec-
tion of this Operator's Manual
(Y page 69) in addition to the child
restraint system manufacturer's installa-
tion instructions
R be sure to observe the instructions and
safety notes on the "Occupant classifica-
tion system (OCS)" (Y page 59) 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 52
Occupant safetySafety

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
modifications could invalidate the vehicle's
general operating permit.
Proper use of the seat belts Observe the safety notes on the seat belt
(Y page 51).
All vehicle occupants must be wearing the
seat belt correctly before beginning the jour-
ney. Also make sure that all vehicle occu-
pants are always wearing the seat belt cor-
rectly while the vehicle is in motion.
When fastening the seat belt, always make
sure that:
R the seat belt tongue is only inserted to the
belt buckle belonging to that seat.
R the seat belt is tight across your body.
Avoid wearing bulky clothing, e.g. a winter
coat.
R the seat belt is not twisted.
Only then can the forces which occur be
distributed over the area of the belt.
R the 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.
R the 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 abdo-
men. 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.
R the seat belt is not routed across sharp,
pointed 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.
R only one person is using a seat belt at a
time.
Infants and children must never travel sit-
ting on the lap of a vehicle occupant. In the
event of an accident, they could be crushed
between the vehicle occupant and seat
belt.
R objects are never secured with a seat belt if
the seat belt is also being used by one of the vehicle's occupants.
Seat belts are only intended to secure and
restrain vehicle occupants. Always observe
the "Loading guidelines" for securing objects,
luggage or loads (Y page 372).
Rear beltbags i
Observe the "Important safety notes" sec-
tion (Y page 56).
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. G
WARNING
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 Occupant safety

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,
please contact an authorized Mercedes-Benz Center.
Further information on child restraint sys-
tems (Y page 69). When triggered, belt bags
:open, increas-
ing the protected area of the occupants' ribc-
ages. The beltbags are triggered depending
on the type and severity of the accident.

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:
R the belt buckle moves forwards to a con-
venient position
R the 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
hazardous situations. This pre-tensions the
seat belt.
Incorporation into the automatic meas-
ures 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. Dam- aged seat belts can no longer fulfill their
protective function and must be replaced.
Visit a qualified specialist workshop. X

Seat belt adjustment The seat-belt adjustment is an integral part of
the PRE-SAFE ®
convenience function. This
function adjusts the driver's and front-
passenger seat belt to the upper body of the
occupants.
The belt strap is tightened slightly when:
R the belt tongue is engaged in the buckle
and
R the 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 adjusting.
You can switch the seat-belt adjustment on
and off using COMAND. Information on
switching the belt adjustment function on and off can be found in the Digital Operator's

Belt warning for the driver and front
passenger The
7 seat belt warning lamp in the instru-
ment cluster is a reminder that all occupants
must fasten 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
warning 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 fastened and the doors
are closed, the 7seat belt warning lamp
lights up. As soon as the driver'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. This warning tone stops after six seconds or when the driver's seat belt is
fastened.
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 driver or front
passenger have fastened their seat belts.
If the driver or front passenger unfasten their seat belts during the journey, the seat belt
warning is activated again.

7seat
belt warning lamp, see "Warning and indi-
cator lamps in the instrument cluster, seat
belts" (Y page 355). Air bags
Introduction The installation point of an air bag can be rec-
ognized by the AIR BAG symbol.
An air bag complements the correctly fas-
tened seat belt. It is no substitute for the seat belt. The air bag provides additional protec-
tion in applicable accident situations.
Not all air bags are deployed in an accident.
The different air bag systems function inde-
pendently from one another (Y page 65).
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 air bag due to the high speed at which the air bag must be deployed.
Important safety notes G
WARNING
If you do not sit in the correct seat position,
the air bag cannot protect as intended and
could even cause additional injury when
deployed. This poses an increased risk of
injury or even fatal injury.
To avoid hazardous situations, always make
sure that all of the vehicle's occupants:
R have fastened their seat belts correctly,
including pregnant women
R are sitting correctly and maintain the great-
est possible distance to the air bags
R follow the following instructions
Always make sure that there are no objects
between the air bag and the vehicle's occu-
pants.
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 out-
side. This allows the air bag to be fully
deployed.
R Always lean against the backrest while driv-
ing. Do not lean forwards or lean against
the door or side window. You may other- 56
