Safety and Security Occupant safety In this section you will learn the most important facts about the restraint systems of the vehicle. The restraint systems are Seat belts ( page 72) Child restraints ( page 76) Additional protection potential provided by Supplemental Restraint System (SRS) with Air bags ( page 62) Air bag control unit (with crash sensors) Emergency Tensioning Device (ETD) for seat belts ( page 75) Seat belt force limiter ( page 75) Roll bars Air bag system components with Passenger front air bag off indicator lamp ( page 70) Passenger seat with Occupant Classification System (OCS) ( page 67) Although independent systems, their protective functions work in conjunction with each other. The SRS system conducts a self-test when the ignition is switched on and in regular intervals while the engine is running. This facilitates detection of malfunctions. The 1 indicator lamp in the instrument cluster comes on when the ignition is switched on and goes out no later than a few seconds after the engine has been started. The SRS components are in operational readiness if the 1 indicator lamp is not lit when the engine is running. A malfunction in the system has been detected if the 1 indicator lamp: fails to go out after approximately 4 seconds after the engine was started does not come on at all comes on after the engine was started or while driving For more information, see the "Practical hints" section ( page 314). i For information on infants and children traveling with you in the vehicle and restraint systems for infants and children, see "Children in the vehicle" ( page 76). 60
