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:
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 41)
R have adjusted their seat and head restraint
properly (Y page 79). 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 (Y page 79).
You also have to make sure that an air bag can
inflate properly if deployed (Y page 43).
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" (Y page 50).
For information on children traveling with you in
the vehicle and on child restraint systems, see
"Children in the vehicle" (Y page 52). Important safety notes
G
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.
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. 38
Occupant safetySafety
Restraint system warning lamp
The functions of the restraint system are
checked after the ignition is switched on and at
regular intervals while the drive system is run-
ning. Therefore, malfunctions can be detected in good time.
The 0075 restraint system warning lamp in the
instrument cluster lights up when the ignition is
switched on. It goes out no later than a few sec- onds after the vehicle is started. The compo-
nents of the restraint system are in operational
readiness.
A malfunction has occurred if the 0075restraint
system warning lamp:
R does not light up after the ignition is switched
on
R does not go out after a few seconds with the
drive system running
R lights up again while the drive system is run-
ning G
DANGER
If the restraint system is malfunctioning,
restraint system components may be trig-
gered unintentionally or may not deploy as
intended during an accident. This can affect
for example the Emergency Tensioning
Device or the air bag. Furthermore, in the
event of an accident, the vehicle's high-volt-
age electrical system may not be deactivated as intended. You may be electrocuted if you
touch the damaged components of the vehi-
cle's high-voltage electrical system. This
poses an increased risk of injury or even fatal
injury.
Have the restraint system checked and
repaired in a qualified specialist workshop as soon as possible. After an accident, switch offthe ignition immediately and remove the key
from the ignition lock. PASSENGER AIR BAG indicator lamp
PASSENGER AIR BAG ON indicator lamp
0043and
PASSENGER AIR BAG OFF indicator lamp 0044are
part of the Occupant Classification System
(OCS).
The indicator lamps display the status of the
front-passenger front air bag.
R PASSENGER AIR BAG ON lights up for 60 sec-
onds, subsequently both indicator lamps are
off (PASSENGER AIR BAG ON and OFF): the
front-passenger front air bag is able to deploy in the event of an accident.
R PASSENGER 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.
If the PASSENGER AIR BAG ON indicator lamp is
off, only the PASSENGER AIR BAG OFF indicator lamp shows the status of the front-passenger
front air bag. The PASSENGER AIR BAG OFF
indicator lamp may be lit continuously or be off.
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.
R Children 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)" (Y page 45) and on "Chil-
dren in the vehicle" (Y page 52). There you
will also find instructions on rearward and
forward-facing child restraint systems on the
front-passenger seat.
R All other persons: depending on the classi-
fication of the person in the front-passenger
seat, the front-passenger front air bag is ena- Occupant safety

bled or deactivated (Y
page 45). Be sure to
observe the notes on "Seat
belts“ (Y page 40) and "Air bags"
(Y page 43). 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:
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
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. Important safety notes The use of seat belts and child restraint systems
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. G
WARNING
If the seat belt is not worn correctly, it cannot perform its intended protective function. An
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 injury
or even fatal injury.
Always ensure that all vehicle occupants have their seat belts fastened correctly and are sit- ting properly. 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
Persons less than 5 ft (1.50 m) tall cannot
wear the seat belt correctly without an addi-
tional and suitable restraint system. If the
seat belt is not worn correctly, it cannot per-
form its intended protective function. An
incorrectly fastened seat belt can also cause
injuries, for example, in the event of an acci-
dent or when braking or changing direction 40
Occupant safetySafety
Seat belts are only intended to secure and
restrain vehicle occupants. Always observe the
"Loading guidelines" for securing objects, lug-
gage or loads (Y page 207).
Fastening and adjusting the seat belts Observe the safety notes on the seat belt
(Y
page 40 )and the notes on correct use of seat
belts (Y page 41).
If the center rear seat belt is being used, also
observe the information about the seat belt for
the center rear seat (Y page 42).Basic illustration

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" (Y page 53).Seat belt for the center rear seat If the left-hand rear seat backrest is folded down
and back up again, the rear center seat belt may lock. The seat belt can then not be pulled out.
X To release the rear center seat belt: pull
the seat belt out approximately 1 in (25 mm)
at the belt outlet on the backrest and then
release it again.
The seat belt is retracted and released.
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.
X Press the release button in the belt buckle,
hold the belt tongue firmly and guide the belt
back.
Belt warning for the driver and front
passenger The
0076 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 0076seat belt warn-
ing lamp lights up for six seconds each time the
drive system is started. If the front doors are
closed and the driver or front-passenger seat
belt has not been fastened, the 0076seat belt
warning lamp lights up again after the
six seconds. As soon as the driver's and front-
passenger seat belts are fastened or a front door is opened again, the 0076seat belt warning
lamp goes out.
If the driver's seat belt is not fastened after the drive system is started, an additional warning
tone will sound. The warning tone switches off
after six seconds or once 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 42
