SUPPLEMENTARY RESTRAINT SYSTEM (SRS) 26 9. Pull out the roof liner assembly and disconnect the curtain air bag connection which is near “B- pillar”. 10.Loosen and remove seven mounting bolts of curtain air bag assembly and carefully remove the air bag assembly. Follow the same procedure for other end also. FITMENT For fitment follow reverse procedure of removal. NOTE After fitment connect the diagnostic tool and clear all fault codes. IV RPLL BELTS RETRACTOR PRETENSIONER LOAD LIMITOR: Seatbelt pre-tensioner is a device installed in vehicles to reduce slack that may exist in a seatbelt system at the moment of a frontal collision. Having the seatbelt system snug allows the supplemental restraint airbag system to work most effectively. A loose seatbelt system does not keep the occupant in the proper position during the forces of a crash. In order for airbags to reduce or eliminate injury, the occupant must be seated, belted and in the correct position in the vehicle. Pre tensioners in seat belts for Driver and Passenger should be fitted only in the vehicle fitted with both frontal airbags. Pre tensioner device is mounted in the retractor unit. The Pretensioner unit essentially consists of a ball cage comprising of a tube of steel balls surrounding a toothed wheel. The wheel is mounted on the belt-webbing spool. When the ECU senses a crash, depending on the crash severity, it sends a "fire" signal to the squib in the belt Pretensioner. The firing of the squib causes displacement of the balls in the tube. The movement of the balls causes rotation of the toothed wheel, which in turn rotates the webbing spool and removes the slack from the belt. LOAD LIMITOR In high speed frontal crashes, passenger moves forward due to inertia at a very high speed. If the seat belt gets locked during such crashes it may cause injuries to the passenger as he is forcibly held by the seatbelt against the inertia force. Load limiters are provided to limit the seat belt loads to a pre-defined value. Load Limiters in seat belts for Driver and Passenger should be fitted only in the
