China Naming Network - Eight-character fortune telling - How to return Cadillac to zero maintenance?

How to return Cadillac to zero maintenance?

After the engine of Pacific Auto Network is turned off, turn on the ignition switch, step on the accelerator pedal three times in five seconds and release it three times. What if? Change the oil as soon as possible? If the message does not appear, zeroing is successful.

What if? Change the oil as soon as possible? If this message is displayed again after the vehicle is started, the engine oil life system has not been reset and the above process should be repeated. Unless the oil is changed, be careful not to accidentally reset the oil life display. Only when the oil is changed next time can it be accurately reset.

Maintenance light is a reminder function set by the car factory for the owner according to a certain mileage or time. It reminds car owners to carry out vehicle maintenance in the form of instrument or screen information or indicator light. The maintenance light returns to zero, that is, after the maintenance is completed, the reminder information returns to zero, that is, the information is reset.

If you go to a 4S shop for maintenance, the oil life will be reset after maintenance, but if you go to a roadside shop for maintenance, few people will reset it. So some of them have just been repaired. Why does the maintenance reminder light come on after a few days? Was it badly maintained last time? In fact, whether the light is on or not has nothing to do with changing the oil. It is purely an electronic product program setting. Even if the oil is not changed, it will not be opened again after reset, and the oil life will be recalculated. If you do normal maintenance and change the oil, even if it is on, don't worry, just reset it, or leave it alone, just remember the mileage and time of the last maintenance and don't forget the next maintenance. The method of resetting the oil life of each car is different, and some cars need a decoder to reset successfully. Therefore, how to reset your car can consult the 4S after-sales service shop or check the maintenance manual yourself. (Photo/Text/Photo: Pacific Auto Network Chen Yalan)
