正確更換汽車后視鏡鏡片(pian)，要先拆(chai)舊鏡片(pian)，分清(qing)左右后連接金屬線，再安裝(zhuang)新(xin)鏡片(pian)并(bing)調整位(wei)置。

更換汽車后(hou)視(shi)鏡(jing)(jing)(jing)鏡(jing)(jing)(jing)片(pian)(pian)，首先要(yao)準備適合(he)車型的后(hou)視(shi)鏡(jing)(jing)(jing)片(pian)(pian)、尖(jian)嘴(zui)鉗(qian)、絕緣膠(jiao)布(bu)、帶(dai)接(jie)口的專用(yong)(yong)(yong)金(jin)屬加熱線(xian)等工(gong)具(ju)。拆舊鏡(jing)(jing)(jing)片(pian)(pian)時，用(yong)(yong)(yong)手壓鏡(jing)(jing)(jing)片(pian)(pian)頭部使尾(wei)部翹起，抓住(zhu)尾(wei)部用(yong)(yong)(yong)力往外(wai)拔，若有加熱接(jie)頭需及時拔掉。區分鏡(jing)(jing)(jing)片(pian)(pian)也很關鍵，左邊(bian)駕駛位鏡(jing)(jing)(jing)片(pian)(pian)帶(dai)L字母(mu)，右邊(bian)帶(dai)R字母(mu)。接(jie)著連接(jie)金(jin)屬線(xian)，用(yong)(yong)(yong)尖(jian)嘴(zui)鉗(qian)剝去后(hou)視(shi)鏡(jing)(jing)(jing)殘留金(jin)屬線(xian)外(wai)皮，與(yu)加熱線(xian)頭一(yi)端(duan)銅線(xian)擰合(he)，并用(yong)(yong)(yong)絕緣膠(jiao)布(bu)包(bao)好。隨后(hou)安(an)裝鏡(jing)(jing)(jing)片(pian)(pian)，手工(gong)接(jie)上(shang)加熱線(xian)頭一(yi)端(duan)金(jin)屬卡扣，與(yu)鏡(jing)(jing)(jing)片(pian)(pian)背面塑料卡托上(shang)方(fang)卡口卡住(zhu)，放入后(hou)視(shi)鏡(jing)(jing)(jing)外(wai)殼內。

整個過程(cheng)中，操作切勿使用蠻力，以免損壞鏡(jing)(jing)片(pian)。安(an)(an)裝完成(cheng)后，要(yao)檢查鏡(jing)(jing)片(pian)位置(zhi)是(shi)否正(zheng)確(que)并進行調整。只(zhi)有掌握正(zheng)確(que)的更(geng)換(huan)(huan)方法，注(zhu)意細節，才能安(an)(an)全(quan)、順(shun)利地(di)完成(cheng)汽車后視鏡(jing)(jing)鏡(jing)(jing)片(pian)的更(geng)換(huan)(huan)，為(wei)安(an)(an)全(quan)駕駛(shi)提(ti)供保(bao)障 。
