What kind of engine oil is used for the first maintenance at a 4S shop?

Most first maintenance services use mineral oil or semi-synthetic oil provided for free during the initial service. Precautions for the first car maintenance: 1. Inquire about costs for items not covered in the first maintenance: Besides changing the engine oil and oil filter, the first maintenance includes a comprehensive inspection and diagnosis of the vehicle's condition and usage. Typically, these services are free. If the technician suggests services not included in the first maintenance, the owner must ask whether there will be charges before deciding to proceed. 2. Maintenance must be done at the designated 4S shop: As long as the first maintenance is performed at the 4S shop within the specified period, the warranty will remain valid even if subsequent maintenance is done elsewhere. However, if the owner fails to take the new car to the designated 4S shop or an authorized service station for the first maintenance within the specified mileage, any issues that arise, even within the warranty period, may require the owner to bear certain repair costs.

How to Open a Car Hood?

Method to open a car hood: For the vast majority of vehicles on the market, the hood release lever is located under the dashboard on the driver's side. Simply pull the latch lightly, and you will hear a click from the hood. Then, proceed to the front of the vehicle to locate a protruding switch to fully open the hood. The car engine, also known as the automobile engine, is the device that provides power to the car, serving as its power source. The car engine determines the vehicle's power performance, fuel economy, stability, and environmental friendliness. Depending on the power source, car engines can be categorized into diesel engines, gasoline engines, electric vehicle motors, and hybrid systems, among others.

What Are the Common Issues After Cleaning the Throttle Body?

Common issues after cleaning the throttle body include an increase in engine idle speed. This occurs because the removal of carbon deposits from the throttle body leads to an increased air intake. Solutions include adjusting the throttle opening size, performing throttle initialization settings, and adjusting the idle fuel supply. The throttle body is a controllable valve that regulates air entering the engine. After entering the intake pipe, the air mixes with gasoline to form a combustible mixture, which then burns to generate power. Connected to the air filter at the top and the engine block at the bottom, the throttle body is often referred to as the "throat" of the car engine. The responsiveness of the car's acceleration is closely related to the cleanliness of the throttle body.

How to Install a Car License Plate?

Method for installing a car license plate: 1. After receiving the license plate, take out the license plate screws and insert them into the anti-theft caps while rotating them; 2. Then, position the license plate correctly and align the screws with the four gaps on the bumper, securing them with a cross screwdriver; 3. After tightening, cover the anti-theft caps and press them in gently. Typically, the received license plate will come with a set of secure screws. According to relevant regulations, both the front and rear vehicle license plates must be installed with four screws each, totaling eight screw holes. The screws must be obtained from the vehicle management office and cannot be privately used for fixing. Failure to comply with the prescribed screw assembly for fixing will result in penalties.

Does ETC need to be reactivated if it falls off?

Yes, it is necessary because the ETC device has an anti-tamper function. There is a small switch on the back of the ETC electronic tag. Once it is peeled off from the windshield, the internal switch will automatically close. Therefore, you must take the vehicle's registration certificate to the ETC service provider for reactivation. ETC's deduction principle: There will be one or more ETC lanes on the highway. Through the dedicated short-range microwave communication between the on-board electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station, and using computer networking technology to settle accounts with the bank, the vehicle can pay the toll without stopping at the bridge or toll station. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: eliminates the hassle of waiting in line; Green and eco-friendly: green and low-carbon, vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear and tear: saves costs, reduces the frequency of vehicle starts and brakes, and lowers wear and fuel consumption; Improved efficiency: the theoretical efficiency of ETC lanes can be increased by 2-3 times, making traditional ETC updates faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key urban clusters will be basically achieved, and the proportion of vehicles equipped with ETC will be significantly increased." It also explicitly set the goal in the "13th Five-Year" comprehensive transportation development indicators: "by 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate for passenger vehicles, the future will also promote the use of ETC for trucks and explore the deep integration of the ETC system with smart transportation development directions such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for car owners. This means more application scenarios will support ETC applications. Here are the precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have a large rearward angle of the windshield, which reduces the driver's field of vision. If this is not considered during ETC installation, it will increase the driver's blind spots. Installing it behind the rearview mirror on the right side can avoid obstructing the view. Do not interfere with charging: The ETC electronic tag requires power, but generally, it does not need to be charged or have its battery replaced because there is a solar panel on the back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and do not place it where the solar panel might be obstructed. Do not remove it casually once installed: The button in the middle of the adhesive is an anti-tamper rod connected to a switch. After the electronic tag is installed, the windshield will press the anti-tamper rod in. If it is removed casually, the rod will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to go to an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. Things to note when using ETC: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the vehicle ahead. The recognition speed for ETC lane passage is 20 kilometers per hour. Driving too fast may prevent the vehicle's device information from being read, leading to a failed fee deduction. When using a debit card linked to ETC, insufficient balance will also result in a failed fee deduction.
