Cars with airbag
When removing the multi-function switch on vehicles equipped with an airbag, be careful and comply with the following conditions.
Warning! Do not disassemble any component of the SRS. Disassembly of components may disable the safety system.
Warning! Avoid contact with solvents or cleaning agents on the airbag.
Transport the airbag separately, bag side up.
Warning! If any SRS component has been dropped or has cracks, dents, or other defects in the housing, bracket, or connector, replace it with new ones.
Warning! When transporting, do not put your hands on the airbag.
Warning! Do not heat the airbag unit to temperatures above 93°C.
Warning! After deploying the airbag, replace the sensor coil spring with a new one.
Warning! Before installing the air bag sensor coil spring, align the mark and the sensor spring neutral pointer with the front wheels set to drive straight ahead. If the coil spring mark is not aligned properly, the steering wheel will not be able to turn fully or the coil spring wire will be damaged, preventing the SRS from working properly.
Order of execution
1. Disconnect the wire from the negative battery terminal.
Warning! Before servicing the airbag system, make sure that at least 30 seconds have passed after the ignition is turned off and the wire is disconnected from the negative terminal of the battery.
Warning! The airbag system is equipped with an emergency power source that allows the airbags to deploy if the battery wires are disconnected in an accident.
