查看汽(qi)車(che)玻璃生產日期，可(ke)通過(guo)觀(guan)察(cha)玻璃上的標識來(lai)判斷，常見位置(zhi)在左(zuo)下角(jiao)或右(you)下角(jiao)。

汽車玻璃的生(sheng)產(chan)(chan)日(ri)期標識(shi)有(you)(you)多種形(xing)式。較為常見的是(shi)數(shu)字(zi)(zi)(zi)加(jia)圓(yuan)(yuan)(yuan)(yuan)點(dian)(dian)(dian)，數(shu)字(zi)(zi)(zi)代(dai)表(biao)(biao)年(nian)(nian)份(fen)(fen)(fen)(fen)(fen)，當圓(yuan)(yuan)(yuan)(yuan)點(dian)(dian)(dian)在數(shu)字(zi)(zi)(zi)前，用(yong)(yong)7減(jian)去點(dian)(dian)(dian)數(shu)可得(de)出(chu)上半年(nian)(nian)的生(sheng)產(chan)(chan)月(yue)份(fen)(fen)(fen)(fen)(fen)；若圓(yuan)(yuan)(yuan)(yuan)點(dian)(dian)(dian)在數(shu)字(zi)(zi)(zi)后，則用(yong)(yong)13減(jian)去點(dian)(dian)(dian)數(shu)，得(de)出(chu)下半年(nian)(nian)的生(sheng)產(chan)(chan)月(yue)份(fen)(fen)(fen)(fen)(fen)。還有(you)(you)數(shu)字(zi)(zi)(zi)加(jia)小圓(yuan)(yuan)(yuan)(yuan)點(dian)(dian)(dian)、大圓(yuan)(yuan)(yuan)(yuan)點(dian)(dian)(dian)等(deng)標識(shi)方式，其中數(shu)字(zi)(zi)(zi)代(dai)表(biao)(biao)年(nian)(nian)份(fen)(fen)(fen)(fen)(fen)，小圓(yuan)(yuan)(yuan)(yuan)點(dian)(dian)(dian)代(dai)表(biao)(biao)季度(du)(du)，大圓(yuan)(yuan)(yuan)(yuan)點(dian)(dian)(dian)代(dai)表(biao)(biao)季度(du)(du)對應的月(yue)份(fen)(fen)(fen)(fen)(fen)。另外(wai)，部分玻璃的生(sheng)產(chan)(chan)日(ri)期標識(shi)是(shi)兩行數(shu)字(zi)(zi)(zi)加(jia)圓(yuan)(yuan)(yuan)(yuan)點(dian)(dian)(dian)，第一行數(shu)字(zi)(zi)(zi)代(dai)表(biao)(biao)年(nian)(nian)份(fen)(fen)(fen)(fen)(fen)、小圓(yuan)(yuan)(yuan)(yuan)點(dian)(dian)(dian)代(dai)表(biao)(biao)月(yue)份(fen)(fen)(fen)(fen)(fen)，第二行大圓(yuan)(yuan)(yuan)(yuan)點(dian)(dian)(dian)代(dai)表(biao)(biao)10天(tian)、小圓(yuan)(yuan)(yuan)(yuan)點(dian)(dian)(dian)代(dai)表(biao)(biao)1天(tian)。

了解汽車玻璃生產日期(qi)十(shi)分重要。對(dui)于購(gou)車者(zhe)而言，能(neng)輔助判斷車輛是否因事故更(geng)換過玻璃；對(dui)于車主來說，可據(ju)此(ci)評估玻璃的(de)使用年限，保(bao)障行車安全；在(zai)售后(hou)服務時，還(huan)能(neng)追溯產品的(de)來源(yuan)和(he)品質。掌握這些(xie)查看方(fang)法，有助于我們更(geng)好(hao)地了解汽車狀況。
