What Does a Flashing Red Key on the Dashboard Mean?

There are two types of red key indicators on the dashboard: one without the KEY symbol, which is the engine immobilizer indicator light. Normally, it turns off after the car starts. If it doesn't turn off, there might be an issue with the anti-theft system. Here is relevant information: 1. Car Anti-Theft System: The car anti-theft system is designed to prevent the car from being stolen and to protect valuable items inside. It mainly consists of electronic control circuits, alarm devices, remote keys, mechanical keys, and actuators. Mechanical door locks prevent the doors from opening automatically while driving but do not provide anti-theft protection. 2. Principle: Without the car key, if the car door is forcibly opened and the ignition is started, the steering wheel will remain locked, making it impossible to drive the car away. Additionally, there are clutch/brake locks, wheel locks, etc., all part of the anti-theft system. Based on the principle of one lock per key, these measures ensure the car's safety.

Can the steering wheel still be turned if the power assist is lost?

It is not recommended to drive when the power steering fails. You should promptly reduce speed, stop the vehicle, and conduct a comprehensive maintenance inspection. The function of the automotive steering system is to control the driving direction according to the driver's intention. The steering system is crucial for driving safety, hence its components are referred to as safety-critical parts. Below is additional information: Power steering assist: Power steering assists the driver in reducing the effort required to turn the steering wheel, and it also plays a role in the safety and fuel efficiency of vehicle operation. When turning, the torque sensor detects the steering wheel's torque and intended turning direction. These signals are transmitted via the data bus to the electronic control unit (ECU). Based on the transmitted torque and intended direction data, the ECU sends commands to the motor controller, which then outputs the corresponding amount of torque as needed, thereby generating power steering assistance.

Is China 6 Emission Standard Mandatory for Shanghai License Plates?

Currently, China 6 emission standard is mandatory for obtaining Shanghai license plates. Below is extended information about China 6: 1. What is China 6 standard? For light gasoline vehicles, carbon monoxide emissions must not exceed 0.5 grams, nitrogen-hydrogen compounds must not exceed 0.035 grams, and particulate matter emissions must not exceed 0.003 grams; while under 'Euro 6' standard: carbon monoxide emissions must not exceed 1 gram, nitrogen oxides must not exceed 0.06 grams, and particulate matter must not exceed 0.005 grams. 2. Impact of China 6 Once China 6 is implemented, vehicles meeting China 5 emission standards will no longer be eligible for registration or transfer. Starting from July 1, 2020, all domestic automobile manufacturers are prohibited from producing 'China 5' models, and imported vehicles must also meet the 'China 6' standard for customs clearance.

Is It Safe to Place a Gas Cylinder in the Car Trunk?

Liquefied gas tanks should not be placed in the car trunk. According to Article 48 of the "Road Traffic Safety Law of the People's Republic of China," motor vehicles are prohibited from carrying flammable and explosive items. If it is necessary to transport flammable and explosive items, approval must be obtained from the public security authorities, and warning signs must be displayed while adhering to the designated route, time, and speed. If a liquefied gas tank is placed in the car trunk without following regulations, it may easily roll during driving. Additionally, bumps and jolts while driving can cause collisions with the tank. In the event of a severe impact, the gas cylinder may explode. The consequences can be imagined—extremely serious. Therefore, for your own safety and the lives of others, never place a liquefied gas tank in the trunk. If the car trunk is sealed during high summer temperatures, the temperature inside can rise significantly. Under such high-temperature conditions, placing flammable and explosive items in the trunk may lead to danger. For short-distance transportation, it is best to secure the liquefied gas tank to prevent movement.

What is the pressure for car refrigerant charging?

Car refrigerant charging pressure is 150 to 250kpa for low pressure and 1300 to 1500kpa for high pressure. Here are the relevant details: 1. Charging automotive refrigerant: It can be charged from either the high-pressure side or the low-pressure side. These two methods differ significantly due to the different states of the refrigerant being charged. High-pressure side charging involves liquid refrigerant, suitable for the initial charging after leak detection and vacuuming. Note that this method requires the engine to be off, and the refrigerant tank must be inverted. The other method, low-pressure side charging, involves gaseous refrigerant and is slower, typically used for refrigerant replenishment. 2. Precautions: When disconnecting, act quickly to avoid excessive refrigerant leakage.

Where is the transmission oil port located?

Transmission oil ports are located on the transmission housing of the vehicle. There are two bolts: the upper one serves as the oil filling port, while the lower one is the oil drain port - this applies to manual transmissions. For automatic transmissions, there are one or two bolts on the lower housing of the transmission, with the larger bolt being the oil drain port and the smaller one the oil filling port. Transmission fluid is crucial for vehicles and requires regular replacement, typically every two years or every 60,000 to 80,000 kilometers. However, this varies depending on the type of transmission, as vehicles have either automatic or manual transmissions. When replacing automatic transmission fluid, the process involves removing the transmission oil pan screw to drain the old fluid before adding new fluid, which only replaces about 70% of the old fluid. For a complete replacement, it's necessary to visit a specialized service center that uses a circulation machine for oil change, achieving over 90% replacement.
