查(cha)(cha)詢汽車前擋(dang)風玻(bo)璃的(de)生產日期(qi)，可通過查(cha)(cha)看擋(dang)風玻(bo)璃上的(de)編碼，依(yi)據數(shu)字(zi)和黑(hei)點位置、數(shu)量來(lai)判斷 。

編(bian)(bian)碼(ma)(ma)(ma)一般位(wei)于前(qian)(qian)擋風玻璃左下方或(huo)右下方，其(qi)中(zhong)數(shu)字(zi)代(dai)表(biao)生(sheng)(sheng)(sheng)產年(nian)份(fen)的(de)(de)末尾一位(wei)數(shu)，要(yao)注意玻璃與(yu)車輛出產日(ri)期不會相(xiang)差10年(nian)。而小(xiao)(xiao)黑(hei)(hei)(hei)(hei)點(dian)(dian)(dian)(dian)(dian)的(de)(de)位(wei)置和數(shu)量則(ze)決定了(le)生(sheng)(sheng)(sheng)產月份(fen)，若(ruo)小(xiao)(xiao)黑(hei)(hei)(hei)(hei)點(dian)(dian)(dian)(dian)(dian)在(zai)數(shu)字(zi)前(qian)(qian)面(mian)，用(yong)7減(jian)去(qu)黑(hei)(hei)(hei)(hei)點(dian)(dian)(dian)(dian)(dian)個(ge)數(shu)；若(ruo)在(zai)數(shu)字(zi)后(hou)面(mian)，就(jiu)用(yong)13減(jian)去(qu)黑(hei)(hei)(hei)(hei)點(dian)(dian)(dian)(dian)(dian)個(ge)數(shu)。部(bu)分(fen)編(bian)(bian)碼(ma)(ma)(ma)后(hou)面(mian)還會有粗小(xiao)(xiao)黑(hei)(hei)(hei)(hei)點(dian)(dian)(dian)(dian)(dian)，這些(xie)粗小(xiao)(xiao)黑(hei)(hei)(hei)(hei)點(dian)(dian)(dian)(dian)(dian)表(biao)示生(sheng)(sheng)(sheng)產周(zhou)(zhou)(zhou)數(shu)，例如(ru)5個(ge)黑(hei)(hei)(hei)(hei)點(dian)(dian)(dian)(dian)(dian)代(dai)表(biao)第一周(zhou)(zhou)(zhou)，4個(ge)黑(hei)(hei)(hei)(hei)點(dian)(dian)(dian)(dian)(dian)代(dai)表(biao)第二(er)周(zhou)(zhou)(zhou)，三(san)(san)個(ge)黑(hei)(hei)(hei)(hei)點(dian)(dian)(dian)(dian)(dian)代(dai)表(biao)第三(san)(san)周(zhou)(zhou)(zhou)。另外，有些(xie)編(bian)(bian)碼(ma)(ma)(ma)形式較為特(te)殊，單排(pai)(pai)編(bian)(bian)碼(ma)(ma)(ma)的(de)(de)，小(xiao)(xiao)黑(hei)(hei)(hei)(hei)點(dian)(dian)(dian)(dian)(dian)分(fen)大、小(xiao)(xiao)，小(xiao)(xiao)黑(hei)(hei)(hei)(hei)點(dian)(dian)(dian)(dian)(dian)表(biao)示季(ji)度，大黑(hei)(hei)(hei)(hei)點(dian)(dian)(dian)(dian)(dian)表(biao)示該季(ji)度的(de)(de)第幾(ji)個(ge)月；兩排(pai)(pai)編(bian)(bian)碼(ma)(ma)(ma)的(de)(de)，第一排(pai)(pai)數(shu)字(zi)代(dai)表(biao)年(nian)份(fen)，小(xiao)(xiao)黑(hei)(hei)(hei)(hei)點(dian)(dian)(dian)(dian)(dian)代(dai)表(biao)月份(fen)，第二(er)排(pai)(pai)大黑(hei)(hei)(hei)(hei)點(dian)(dian)(dian)(dian)(dian)代(dai)表(biao)10天，小(xiao)(xiao)黑(hei)(hei)(hei)(hei)點(dian)(dian)(dian)(dian)(dian)代(dai)表(biao)1天。對于等特(te)殊車型，若(ruo)玻璃編(bian)(bian)碼(ma)(ma)(ma)沒有黑(hei)(hei)(hei)(hei)點(dian)(dian)(dian)(dian)(dian)，需輸(shu)入玻璃串碼(ma)(ma)(ma)到專(zhuan)門網站(zhan)查(cha)詢。

了(le)解前擋風玻璃(li)生產日期(qi)的查(cha)詢方法很(hen)有用，在(zai)購車尤其是買二手車時，能據此判斷(duan)玻璃(li)是否被(bei)更(geng)換，也能更(geng)好地了(le)解車輛零部件信息。
