Occupant safety OCS Self-test After turning the SmartKey in the starter switch to position 1 or 2 or pressing the KEYLESS-GO start/stop button once or twice, the 42 indicator lamp illuminates. If an adult occupant is properly sitting on the front passenger seat and the system classifies the occupant as an adult, the 42 indicator lamp will illuminate and go out after approximately 6 seconds. If the seat is not occupied and the system classifies the front passenger seat as being empty, the 42 indicator lamp will illuminate and not go out. 49 Seat belts Safety notes The use of seat belts and infant and child restraint systems is required by law in all 50 states, the District of Columbia, the U.S. territories and all Canadian provinces. Even where this is not the case, all vehicle occupants should have their seat belts fastened whenever the vehicle is in motion. G Warning! i See "Children in the vehicle" (Y page 56) for information on Rinfants and children traveling with you in the vehicle Rrestraint systems for infants and children G Warning! Always fasten your seat belt before driving off. Always make sure all of your passengers are properly restrained. You and your passengers should always wear seat belts. Failure to wear and properly fasten and position your seat belt greatly increases your risk of injuries and their likely severity in an accident. If you are ever in an accident, your injuries can be considerably more severe without your seat belt properly buckled. Without your seat belt buckled, you are much more likely to hit the interior of the vehicle or be ejected from it. You can be seriously injured or killed. In the same crash, the possibility of injury or death is lessened if you are properly wearing your seat belt. The air bags can only protect as intended if the occupants are properly wearing their seat belts. If the 42 indicator lamp does not illuminate, the system is not functioning. You must contact an authorized Mercedes-Benz Center before seating any child on the front passenger seat. For more information, see the "Practical hints" section (Y page 498). G Warning! Never place anything between seat cushion and child seat (e.g. pillow), since it reduces the effectiveness of the OCS. The bottom and back of the child seat must make full contact with the passenger seat cushion and backrest. If necessary, adjust the tilt of the passenger seat backrest. An incorrectly mounted child seat could cause injuries to the child in case of an accident, instead of increasing protection for the child. Follow the manufacturer's instructions for installation of child seats. G Warning! Never ride in a moving vehicle with the seat backrest in an excessively reclined position as this can be dangerous. You could slide under the seat belt in a collision. If you slide under it, the seat belt would apply force at the abdomen or neck. That could cause serious or even fatal injuries.
