大众朗逸仪表盘故障灯出现一个圆圈,旁边还有个叹号是什么意思?
推荐回答(2个)
仪表盘故障灯出现一个圆圈,旁边还有个叹号可能是汽车制动系统故障灯,亮的原因可能是:
1、ABS功能失效。
2、刹车片磨损严重,已经失效。
3、刹车油不符合要求。
制动系统出现异常,表现在制动不良或失灵、制动单边跑偏、制动噪音、制动拖滞引起的制动鼓发热、驻车制动器失灵。

故障的判断与排除
1、连续踩下制动踏板,如踏板逐渐升高且有弹性感觉,但稍停一会后再踩踏板时仍然很低,即为制动系统内有空气,这时应对制动系统进行排气
2、一脚制动不灵,但连续踩几次踏板时制动效果很好,一般为制动踏板自由行程过大或制动间隙过大。应调整踏板自由行程,而后检查制动器间隙,必要时进行制动器解体修理。
3、踩下制动踏板时,不软弱不沉,但就是制动效果不良,这一现象为车轮制动器故障,如制动蹄片有油或接触不良、摩擦片老化、磨损、制动鼓磨损不均。应对制动技术状况进行检查,必要时进行调整和修复。

手刹车灯或缺制动液报警灯,如果手刹车拉起亮是正常的,松开手刹车仪表盘内灯熄灭;缺制动液报警灯,制动液加注口有个常开的传感器,当制动液油面下降到指定位置传感器接通,仪表盘指示灯点亮需要补加制动液。
该指示灯常亮代表发动机以及电子系统出现了故障,如在点火后或行驶过程中该灯常亮不灭或闪动,则代表管理系统检测到了发动机或是汽车仪表故障指示灯,请立即与服务站联系。
车辆启动以后故障灯如果一直亮表示发动机电控系统出现故障了。一般原因可能是发动机传感器故障,或者执行器损坏导致的。
仪表盘开发过程远比它表面看起来困难。仪表盘必须提供丰富信息,但又不能让用户太分心。它需支持用户快速浏览信息并能深入了解详细信息,还得是恰当的信息。
手刹,发动机,安全带,电池,epc,还有气囊灯,侧滑灯,胎压灯,ABS等,打开开关后,某些系统在5秒没自检完毕,功能正常的情况下,自行熄灭。有些灯要在启动车辆才能自检的,所以不着车,它就一直亮着,一般情况启动车辆后还常亮的时候就是该系统存在异常。
手刹的标志, 拉起手刹 灯亮,放下灯灭,如果灯还亮那就考虑刹车油是否缺少了,如果真是这种情况,需要到汽车修理店买一瓶汽车制动液加上就好了。
起停功能,就是在你正常行驶时踩住刹车停车会自动熄火,松开刹车又会自动启动。
