1、直接打開主界面，點擊城市服務進入。

2、下壹步，需要在車主那裏選擇ETC服務跳轉。
/iknow-pic.cdn.bcebos.com/dbb44aed2e738bd4a31a7560ae8b87d6277ff9ac"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/dbb44aed2e738bd4a31a7560ae8b87d6277ff9ac?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/dbb44aed2e738bd4a31a7560ae8b87d6277ff9ac"/>
3、如果沒問題，就繼續點擊三秦通的ETC充值。

4、這個時候，根據實際情況填寫相關資料並選擇提交信息。
/iknow-pic.cdn.bcebos.com/2e2eb9389b504fc2501e7454eadde71190ef6d1a"target="_blank"title=""class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/2e2eb9389b504fc2501e7454eadde71190ef6d1a?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="/2e2eb9389b504fc2501e7454eadde71190ef6d1a"/>
5、這樣壹來會提示etc卡網上充值成功，即可達到目的了。
