進行保(bao)養燈歸(gui)零操作，有手動、電腦、按(an)鍵歸(gui)零以(yi)及(ji)重置保(bao)養周期等多種方(fang)式，且因車型(xing)不(bu)同而(er)存在差異。

手動歸(gui)(gui)(gui)零(ling)(ling)(ling)需按(an)(an)(an)(an)(an)下車輛(liang)(liang)儀(yi)表(biao)盤特(te)定按(an)(an)(an)(an)(an)鈕(niu)組合或按(an)(an)(an)(an)(an)車輛(liang)(liang)手冊指(zhi)導操作。例如東風（||），關(guan)(guan)閉(bi)點火開關(guan)(guan)，按(an)(an)(an)(an)(an)下組合儀(yi)表(biao)上單次(ci)計(ji)(ji)程(cheng)(cheng)(cheng)表(biao)歸(gui)(gui)(gui)零(ling)(ling)(ling)按(an)(an)(an)(an)(an)鈕(niu)并保(bao)(bao)持，打開點火開關(guan)(guan)，里程(cheng)(cheng)(cheng)表(biao)顯示屏(ping)倒(dao)計(ji)(ji)數到0000.0時松開按(an)(an)(an)(an)(an)鈕(niu)，保(bao)(bao)養(yang)(yang)(yang)燈(deng)(deng)即歸(gui)(gui)(gui)零(ling)(ling)(ling)。電腦歸(gui)(gui)(gui)零(ling)(ling)(ling)則是在4S店保(bao)(bao)養(yang)(yang)(yang)時，保(bao)(bao)養(yang)(yang)(yang)師傅用(yong)專業(ye)設備連(lian)接(jie)車輛(liang)(liang)OBD接(jie)口，使用(yong)診斷儀(yi)或掃(sao)描(miao)儀(yi)操作，這(zhe)種方式方便快捷(jie)且準(zhun)確(que)(que)。按(an)(an)(an)(an)(an)鍵歸(gui)(gui)(gui)零(ling)(ling)(ling)，部分車型(xing)儀(yi)表(biao)盤有(you)專門按(an)(an)(an)(an)(an)鍵，按(an)(an)(an)(an)(an)特(te)定按(an)(an)(an)(an)(an)鍵組合就能歸(gui)(gui)(gui)零(ling)(ling)(ling)，像上海通用(yong)別克（||），點火開關(guan)(guan)ON，5s內連(lian)續將加(jia)速踏(ta)板踩(cai)下3次(ci)，保(bao)(bao)養(yang)(yang)(yang)燈(deng)(deng)便可消除。至(zhi)于重置保(bao)(bao)養(yang)(yang)(yang)周期，適用(yong)于里程(cheng)(cheng)(cheng)計(ji)(ji)數器被清零(ling)(ling)(ling)的車型(xing)，手動重置里程(cheng)(cheng)(cheng)計(ji)(ji)數器可歸(gui)(gui)(gui)零(ling)(ling)(ling)保(bao)(bao)養(yang)(yang)(yang)燈(deng)(deng)，但可能影響保(bao)(bao)養(yang)(yang)(yang)記錄的準(zhun)確(que)(que)性。

不(bu)同車型的保(bao)(bao)養燈歸零(ling)(ling)(ling)方法各有(you)不(bu)同，車主在操作前(qian)應仔細查閱車輛手冊(ce)。若對操作仍有(you)疑慮，去4S店(dian)由專(zhuan)業(ye)人員進行歸零(ling)(ling)(ling)是更可靠(kao)的選擇，這樣能確保(bao)(bao)保(bao)(bao)養燈正確歸零(ling)(ling)(ling)，保(bao)(bao)障車輛的正常維護與使用。
