When the car dashboard displays "normal-mode" and the vehicle cannot be started, it is usually due to the fact that the car's battery is 亏电.

The specific reason is:

The most common cause is using internal electrical appliances for a long time while the engine is off, such as listening to music or turning on the air conditioning. If the battery is frequently discharged, it will cause permanent damage to the battery and shorten its lifespan. There may also be problems such as ABS sensor failure or starter failure.

The solution is:

First, charge the battery using a jump start from another vehicle. If the battery is only discharged, this will solve the problem. If the battery is still not charged after using a jump start, it is recommended to seek assistance from a 4S store or a professional technician.
