Ilokhi yokuqala yesicabha semoto iyingidi yesicabha eyimishini, esanda kusetshenziswa ukuvimbela isicabha semoto ukuthi sivuleke ngokuzenzakalelayo lapho kwenzeka ingozi, dlala indima yokuphepha ekushayeleni kuphela, hhayi indima emelene nobugebengu.Ngokuthuthuka komphakathi, ukuthuthukiswa kwesayensi nobuchwepheshe kanye nokwanda okuqhubekayo kobunikazi bezimoto, iminyango yezimoto namaloli akhiqizwa kamuva afakwe isikhiye somnyango esinokhiye.Lo khiye wesicabha ulawula isicabha kuphela, kanti ezinye izicabha zivulwa noma zihluthulwe ngenkinobho yokukhiya isicabha ngaphakathi emotweni.Ukuze udlale kangcono indima yokulwa nobugebengu, ezinye izimoto zifakwe ingidi yokuqondisa.Isingidi sokuqondisa sisetshenziselwa ukukhiya umshini wokuqondisa imoto.Ilokhi yesiteringi itholakala nesikhiya sokushisa ngaphansi kwesiteringi, esilawulwa ukhiye.Okusho ukuthi, ngemuva kokuthi i-ignition lock inqamule i-ignition circuit ukuze ucime injini, vula ukhiye wokushisa kwesokunxele futhi endaweni elinganiselwe, futhi ulimi lokukhiya luzodlulela ku-slot shaft yokuqondisa ukuze ukhiye umshini wokushayela imoto.Ngisho noma umuntu evula isicabha ngokungemthetho aqhumise injini, isiteringi siyakhiywa futhi imoto ayikwazi ukujika, ngakho ayikwazi ukuhamba, ngaleyo ndlela idlala indima yokulwa nobugebengu.Ezinye izimoto zakhiwe futhi zakhiwe ngaphandle kwengidi yokuqondisa, kodwa zisebenzisa enye ebizwa ngokuthi i-crutch lock ukukhiya isiteringi, ukuze isiteringi singajiki, sikwazi ukudlala indima yokulwa nobugebengu.
I-point switch isetshenziselwa ukuvula noma ukuvala isekethe yokuthungela injini, ngokusho kokhiye wokuvula ilokhi, kodwa futhi idlala indima ethile ekulweni nobugebengu.
