There are two solutions when the BYD Song battery runs out and fails to start: 1. Jump-starting: Contact a rescue vehicle, connect the jumper cables, and temporarily charge the battery through the rescue vehicle to start the engine. This is the correct approach. To avoid being unable to charge when the car battery is dead, always keep a set of jumper cables in the car. When connecting the jumper cables, it is crucial not to mix up the connection sequence. First, connect the positive terminal of the dead battery to the positive terminal of the rescue vehicle's battery. Then, connect the negative terminal of the rescue vehicle's battery to a metal part (ground) in the engine compartment of the dead car. After connecting the jumper cables, start the rescue vehicle's engine and slightly increase its RPM. After about 5 minutes, the dead car can be temporarily charged. Once charging is complete, remove the jumper cables in the reverse order of connection. 2. Push-starting or Towing-starting: In the absence of jumper cables, push-starting or towing-starting is the most familiar and effective emergency starting method. However, this should not be used frequently as it may cause some damage to the engine and clutch, especially for automatic transmission vehicles, which should avoid using this method to start.

Can Traffic Violation Cameras See People Inside the Car?

Traffic violation cameras can capture people sitting in the rear seats of the vehicle. Here is some information about traffic violation monitoring: 1. Definition: Violation photography refers to the process where vehicles breaking traffic laws are recorded by camera equipment. 2.
