Instruments and controls Operation Driving Instrument cluster display 92 Practical hints Car care Technical data Index Restraint systems come on at all or if it fails to extinguish after approximately 4 seconds or if it comes on thereafter, a malfunction in the system has been detected. The following system components are monitored or undergo a self-check: crash-sensor(s), airbag ignition circuits, front seat belt buckles, emergency tensioning retractors, seat sensor. Initially, when the electronic key is turned from starter switch position 0 to position 1 or 2, malfunctions in the crash sensor are detected and indicated (the "SRS" indicator lamp stays on longer than 4 seconds or does not come on). Have the system checked at your authorized Mercedes-Benz Center immediately. In the operational mode, after the indicator lamp has gone out following the initial check, interruptions or short circuits in the airbag ignition circuit and in the driver and front passenger seat belt buckle harnesses, and low voltage in the entire system are detected and indicated. Warning! In the event a malfunction of the "SRS" is indicated as outlined above, the "SRS" may not be operational. For your safety, we strongly recommend that you visit an authorized Mercedes-Benz Center immediately to have the system checked; otherwise the "SRS" may not be activated when needed in an accident, which could result in serious or fatal injury, or it might deploy unexpectedly and unnecessarily which could also result in injury. Note: See page 305 for information on the Supplemental Restraint System (SRS) indicator lamp. The driver and passenger front airbags are designed to activate only in certain frontal impacts exceeding a preset threshold. The front passenger airbag deploys only if the front passenger seat is occupied and the 7 indicator lamp on the center console is not illuminated. Note: Heavy objects on the front passenger seat can appear to the "SRS" to indicate the presence of an occupant in that seat which causes the passenger front airbag to deploy in a crash exceeding the appropriate threshold.
