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:

• Seat belt system
• Air bags
• Child restraint system
• 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:
• have fastened their seat belts correctly (Y page 46)
• have the seat and head restraint adjusted properly (Y page 94)

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 94).
You also have to make sure that an air bag can inflate properly if deployed (Y page 49).
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. However, seat belts and airbags 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 56). See “Children in the vehicle” for information on children traveling with you in the vehicle as well as on child restraint systems (Y page 59).

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. 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 that have been approved specifically for your vehicle by Mercedes-Benz.

Restraint system warning lamp
The functions of the restraint system are checked after the ignition is switched on and at regular intervals while the engine is running. Therefore, malfunctions can be detected in good time.
The 6-restraint system warning lamp on the instrument cluster lights up when the ignition is switched on. It goes out no later than a few seconds after the vehicle is started. The compo-nents of the restraint system are in operational readiness.
A malfunction has occurred if the 6restraint system warning lamp:

• does not light up after the ignition is switched on
• does not go out after a few seconds with the engine running
• lights up again while the engine is running

WARNING
If the restraint system is malfunctioning, restraint system components may be triggered unintentionally or may not deploy as intended during an accident. This can affect for example the Emergency Tensioning Device or the air bag. 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.

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 airbag.

• PASSENGER AIR BAG ON lights up for 60 seconds, 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.
• PASSENGER AIR BAG OFF lights up: the front passenger’s front air bag is deactivated. It will then not be deployed in the event of an accident.
  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 following points. You must make sure of this both before and during a journey.

Children in a child restraint system:
whether the front-passenger front air bag is enabled or deactivated depends on the install-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 51) and on “Children in the vehicle” (Y page 59). There you will also find instructions on rearward and forward-facing child restraint systems on the front-passenger seat.

All other persons:
depending on the classification of the person in the front passenger seat, the front-passenger front air bag is ena-
bled or deactivated (Y page 51). Be sure to observe the notes on “Seat belts“ (Y page 44) and “Air bags”
(Y page 48). There you can also find information 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 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. Furthermore, the seat belt helps to keep the vehicle occupant in the best position in relation to the air bag.
The seat belt system comprises:
Seat belts
Emergency Tensioning Devices and seat 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 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 not occupied, do not engage the seat belt tongue in the buckle on the front-passenger seat. Other-wise, the Emergency Tensioning Device and side impact air bag could be triggered in the event of an accident and would need to be replaced.

Important safety notes
The use of seat belts and child restraint systems is required by law in:

• all 50 states
• the U.S. territories
• the District of Columbia
• all Canadian provinces
  Even where this is not required by law, all vehicle occupants should correctly fasten their seat belts before starting the journey.

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.

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 (Y page 46)
Rhave the seat and head restraint adjusted properly (Y page 94)

WARNING
The seat belt does not offer the intended level of protection if you have not moved the backrest 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.
Persons less than 5 ft (1.50 m) tall cannot wear the seat belt correctly without an additional 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 accident or when braking or changing direction abruptly. This poses an increased risk of injury or 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:

• 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
• always observe the instructions and safety notes on “Children in the vehicle”
  ( page 59) in addition to the child restraint system manufacturer’s installation and operating instructions
• always observe the instructions and safety notes on the “Occupant classification system (OCS)” (Y page 51)
