What is the function of turning on AC with car heater?

AC switch is the cooling switch of the car air conditioning. After pressing the AC switch, the compressor clutch of the car air conditioning will engage, and the engine can drive the compressor to operate. The following are the functions of AC: When the compressor is running, it can continuously compress the refrigerant and deliver it to the evaporator. The refrigerant can continuously expand and absorb heat in the evaporator, thereby cooling the evaporator. The cooled evaporator can cool the air blown by the blower, so that the car air conditioning vents can blow cold air. When using the car heater, there is no need to press the AC button, for the following reasons: The AC button controls the compressor switch, while the heater mainly uses the internal heat circulation of the car to maintain the temperature inside the car. During this process, the compressor does not work, and only the air volume needs to be adjusted. Turning on the AC button may cause unnecessary fuel consumption. There are four precautions for using the heater in winter. Do not use the heater immediately after a cold start: When the car is started cold, the temperature in the radiator is relatively low. If the heater is turned on, it will not only fail to increase the temperature inside the car but also increase the burden on the engine, slow down the engine temperature rise, affect normal use, and increase fuel consumption. It is recommended to wait 8-15 minutes after starting the car before turning on the heater. Control the heater system through the water temperature gauge: Do not turn on the heater when the water temperature gauge is at a low position. When the water temperature gauge reaches the middle position, you can use the heater. When using the heater, it is recommended to first use the external circulation to expel the cold air inside the car, which can quickly increase the temperature inside the car. Turn off the heater when parking for a long time: Especially when waiting for someone, if the time is too long, the heater should be turned off. Keeping the heater on for a long time can easily lead to carbon monoxide poisoning. If the heater needs to be used for a long time, you can leave a small gap in the window. Turn off the heater before turning off the engine: If the heater is not turned off, the next time you start the car, the heater will be turned on before the engine starts, which will affect the car air conditioning over time.

What is the function of the hazard lights automatically turning on during emergency braking?

Emergency braking hazard lights automatically turning on is a function of the emergency brake indicator. Reasons for hazard lights automatically turning on: Some higher-end vehicles are equipped with this feature, which is preset by the manufacturer. When the vehicle performs emergency braking, the hazard lights start flashing to warn vehicles behind that the front vehicle is encountering an issue, thereby preventing rear-end collisions. Conditions for hazard lights automatically turning on: Generally, this function activates when emergency braking occurs at speeds exceeding 60 kilometers per hour. Some vehicles may activate it at 80 kilometers per hour. The exact threshold varies slightly between different car models.

Can a car be inspected in a different location?

Vehicles can be inspected in different locations. Vehicle Annual Inspection Authorization: First, the vehicle owner needs to obtain an Authorization for Inspection Notice from the original registration vehicle management office. There are no restrictions on the owner themselves, so the owner can authorize a friend to act as an agent at the original registration location. Required documents for the authorization: the owner's ID card, vehicle license, vehicle insurance information, original vehicle and vessel tax receipt, application for out-of-town annual inspection, etc. If an agent is being used, an authorization certificate from the owner is required. The owner can then go to the current vehicle management office to inquire about the relevant vehicle information. After verifying the authorization for annual inspection, the normal out-of-town vehicle inspection can proceed. Relevant regulations: According to the registered address information on the vehicle license, the vehicle management branch can handle the authorization for annual inspection in a different location. Any unprocessed violations at the place of use must be resolved in advance. For an out-of-town authorization for annual inspection, the following must be submitted: the valid vehicle license, the original compulsory traffic liability insurance (CTPL) policy, and, if an agent is used, the agent's ID. The vehicle management branch will then issue an Authorization for Inspection certificate, after which the vehicle can be inspected at the place of use. Vehicles in other locations must be inspected separately; apply at the vehicle management office where the license was issued, and pay fines at the location where the violation occurred (if the violation occurred elsewhere and the record has been transferred to the local vehicle management office, then pay locally). Vehicles that cannot undergo inspection on schedule due to long-term assignments elsewhere must be authorized by the owner, who should apply to the original vehicle management office to entrust the inspection to the local vehicle management office at the place of residence. After inspection, the results should be reported to the original vehicle management office. Vehicles that cannot undergo annual inspection on schedule due to special circumstances should apply for an extension with the local vehicle management office in advance. The vehicle owner or user must fill out the annual inspection form and submit it to the designated location by the date specified by the local vehicle management office. If the vehicle passes inspection, the vehicle management authority will stamp the vehicle license and the annual inspection form (the vehicle management office marks the inspection as valid for the year ***). To apply for an out-of-town annual inspection, the vehicle owner must go to the vehicle management branch corresponding to the address listed on their ID (for corporate entities, the organization code certificate is required). Required documents: the vehicle registration certificate or license, and the agent can bring the original ID card. After the vehicle passes inspection at the inspection location, the vehicle owner (or agent) must fill out an application form and submit the vehicle license, compulsory traffic liability insurance certificate, Authorization for Inspection Notice, and vehicle safety technical inspection certificate to the authorized vehicle management office to apply for the inspection mark.

How is reverse driving on highways captured?

Reverse driving on highways is captured through electronic and manual cameras. Electronic cameras: Electronic cameras are generally installed at key sections of the highway, such as the entry and exit ramps, and some cameras may be hidden. The cameras take two photos, for example, one second apart, and then compare them to determine if a vehicle is reversing. Manual cameras: Some sections also employ manual cameras to capture reverse driving on highways. Manual capture typically involves monitoring the surveillance feed. If a vehicle reversing on the highway is spotted on the screen, the operator will control the camera to capture images of the reversing vehicle.
