For the vehicles equipped with additional system of restriction of movement NPB (an inflatable safety cushion):

  • Service of components of an inflatable safety cushion (NPB) and near them or works with electroconducting should be carried out only by the authorized dealer of SUZUKI. Non-compliance with security measures can lead to inadvertent operation of system or put system out of action. Any of these two conditions can lead to a serious trauma.

It is necessary to replace them with details having the same number or equivalent if such replacement is necessary. Do not use for replacement of a detail of the worst quality or substitutes. It is necessary to observe the specified values of a torque of an inhaling at assembly to provide long service life of all details. It is not necessary to use welding as it can lead to extensive damages and weakening of metal.
