Should You Release the Handbrake or Shift to D Gear First When Starting an Automatic Transmission Car?

When starting an automatic transmission car, first shift to D gear and then release the handbrake. It is essential to keep the brake pedal pressed. The order can be reversed without major issues, but it is crucial not to forget to release the handbrake. Starting with the brake pedal pressed can easily burn out the brake pads. If you're a beginner and not yet accustomed to the process, you can release the handbrake first to avoid forgetting it after starting. Whether it's a manual or automatic transmission car, the most important step when starting is to shift into gear first and then release the handbrake. The handbrake serves as the final safety measure. Only after fully engaging the gear and before moving should you release the handbrake—this practice is very safe. When shifting gears, move quickly from P to D to avoid passing through R, which can cause a backlash and harm the transmission. If you engage the gear but do not release the handbrake, all the power output from the engine will be absorbed by the torque converter, causing its temperature to rise sharply. Prolonged exposure to this condition can burn out the torque converter. For dual-clutch transmissions, after engaging the gear, the clutch friction plates will remain in a semi-engaged state. Prolonged semi-engagement can lead to burning out the friction plates, so it's necessary to start moving as soon as possible. Generally, if you don't press the brake pedal before starting an automatic transmission car, it can negatively impact the vehicle's transmission and gear structure. This effect is even more pronounced when the car is parked on an incline.

How Often Should the Fuel System Be Cleaned?

Fuel system cleaning is generally recommended every 2 years or approximately 60,000 kilometers. The steps for cleaning the fuel system are as follows: 1. Clean the fuel tank: Turn off the power, unplug the fuel sensor connector, remove and take out the electric fuel pump or fuel sensor, open the fuel tank cap, remove the filter screen, use a hose to extract the fuel from the tank, leaving about 5~8cm of fuel, then add a certain amount of ethanol or cleaning agent. Connect one end of a plastic hose to an air pump and insert the other end into the bottom of the fuel tank through the fuel tank opening. Use 3MPa air pressure to blow and clean, so that various impurities accumulated at the bottom of the tank, such as dirt, rust, and gum particles, are washed away by the agitated cleaning oil. 2. Clean the electric fuel pump: Use a carburetor cleaner to remove various impurities attached to the fuel pump. For mechanical fuel pumps that can be disassembled, the main cleaning parts are the inlet valve, outlet valve, and oil cup. For aged fuel pump diaphragms, replace them with new ones. For non-disassembled mechanical fuel pumps, replace them with new ones as needed. Replace the fuel sensor float in the tank if it affects the accuracy of the sensor. 3. Clean the fuel injector: Use a specialized carburetor cleaner to clean the oil passages, metering holes, oil surface chamber, atomizing nozzle, needle valve, etc. Replace the polymer plastic fuel float with a copper or stainless steel one. After cleaning, the carburetor should be clean and free of attached impurities. After reassembly, perform operational performance debugging to ensure the engine maintains stable idle speed, smooth transitions between high and low speeds, and no backfire or popping. 4. Clean the fuel filter: For detachable filters, use specialized cleaning oil to clean the oil cup and filter element. Polymer plastic filter elements must be replaced with ceramic or steel mesh nylon fabric filter elements. Replace disposable fuel filters. 5. Clean the electronic fuel injector: The electronic fuel injector of an electronic fuel injection vehicle should be cleaned on a specialized cleaning bench. Use specialized cleaning agents or carbon removers to thoroughly remove carbon particles and stains from the injector. After cleaning, verify the fuel injection quality before reassembly. 6. Clean the fuel supply lines and various filters: Use specialized cleaning oil or a cleaning machine for cleaning. 7. Check the fuel tank breather valve: The fuel tank's intake and exhaust should be unobstructed. If not, the breather valve must be cleared or replaced. 8. Test drive inspection: After cleaning, add ethanol gasoline to the vehicle and start it. Inspect all components of the fuel system to ensure there are no leaks, and check and adjust the operational performance of each part.

Can the ETC card be replaced?

If the IC card is damaged, it can be replaced. You can go to the counter with your ID card to replace it. The first IC card is free, while the second one incurs a fee. If the bank supports keeping the same card number, you can get a new IC card with the same number. If not, each card will have a different number, but the password, SMS notifications, and balance will remain unchanged. ETC stands for Electronic Toll Collection, which is an electronic toll system. To apply for ETC, you need to provide the original and photocopies of the vehicle owner's valid ID card and vehicle registration certificate. If someone else is handling the application on behalf of the owner, they must also bring their own valid ID card. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. Additionally, you will need a bank card for deducting highway toll fees. Applicants must be between 18 and 60 years old, and the vehicle must be registered under their name. For company vehicles, the required documents include: An introduction letter from the vehicle owner (with official seal); a photocopy of the organization code certificate or business license (with official seal); the original ID card of the agent; the original vehicle registration certificate; and the vehicle that needs to have ETC installed. Here are some installation precautions for ETC: Do not obstruct the driver's view. It is best to install it behind the rearview mirror. Many car models have a steeply angled windshield, which can reduce the driver's field of vision. If ETC is installed without considering this, it may increase blind spots. Installing it on the right side behind the rearview mirror can help avoid obstructing the view. Do not interfere with charging. The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a solar panel on the back for self-charging. Therefore, during installation, avoid the blackened areas on the windshield and positions that might block the solar panel. Once installed, do not remove it arbitrarily. The adhesive in the middle has an anti-tamper rod connected to a switch. After installation, the windshield will press the anti-tamper rod in. If the tag is removed, the rod will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To avoid issues caused by the ETC device of the vehicle in front malfunctioning, maintain a distance of at least 10 meters from the vehicle ahead to prevent automatic toll deduction for the wrong vehicle. The ETC lane recognizes vehicles at a speed of 20 km/h. Driving too fast may result in failure to read the vehicle's device information, leading to toll deduction failure. If a debit card is linked to ETC, insufficient balance will also cause toll deduction to fail.

Does ETC have to be handled by the vehicle owner personally?

ETC can also be handled by non-owners. According to the "Implementation Plan for Accelerating the Application Service of Electronic Non-stop Toll Collection on Expressways" issued by the Ministry of Transport, the original valid ID card of the vehicle owner, the original and photocopy of the vehicle registration certificate (providing the page with the latest annual inspection stamp) are required. For handling on behalf of others, the original valid ID card of the agent is also needed. If applying for ETC through major bank branches, a debit card or credit card from the corresponding bank must be prepared. Some banks only support ETC binding with credit cards, while others may require freezing a portion of the amount as a deposit when binding ETC with a debit card. Documents required for company vehicles: Introduction letter from the vehicle owner (with official seal); Copy of the organization code certificate or business license (with official seal); Original ID card of the agent; Original vehicle registration certificate; Vehicle to be equipped with ETC. ETC deduction principle: There will be one or more ETC lanes on the expressway. Through dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane of the toll station, and using computer networking technology for backend settlement with the bank, the purpose of paying tolls without stopping at the toll station is achieved. All this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of queuing and waiting; Green and eco-friendly: 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, lowering wear and fuel consumption; Improved efficiency: The theoretical efficiency of ETC lanes can be increased by 2-3 times, making traditional ETC newer, 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," and explicitly set the goal in the main indicators of comprehensive transportation development during the "13th Five-Year Plan" period that "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 the development directions of smart transportation such as vehicle-to-vehicle communication and vehicle-road coordination, providing comprehensive travel services for vehicle owners. This means more application scenarios will support ETC applications. ETC usage precautions: The ETC transaction sensing area is 8 meters. When the vehicle in front stops, to prevent the ETC device failure of the vehicle in front or the absence of an ETC device, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the vehicle in front. The recognition speed for ETC lane passage is 20 km/h. If the speed is too fast, the vehicle device information cannot be read, leading to deduction failure. Unauthorized removal or movement of the OBU device, or detachment or loosening of the ETC electronic tag, will cause the electronic tag to fail. It can be sent to the bank where the ETC card was processed or the expressway service office for testing. If the loosening or detachment is not man-made, it only needs to be reactivated. When using a debit card bound to ETC, insufficient balance will also cause deduction failure. Follow the guidance of on-site staff to use the manual MTC lane and pass by cash or card. Poor sensing due to overly thick car windshields. Especially for vehicles that have had accidents and had their windshields replaced, or those who have modified their front windshields, need to pay attention.

How do motorcycles brake?

Motorcycle braking methods: First release the throttle and straighten the bike body, apply the rear brake first then the front brake. Never lock the brakes completely - allow the wheels to rotate slightly without sliding (maintain rolling motion). The best practice is simultaneous front and rear braking, as the front brake is primarily designed to assist the rear brake in achieving complete stopping power. Using either brake alone cannot achieve the shortest braking distance - optimal braking effect requires combined operation. Motorcycles are gasoline-powered vehicles with handlebar-controlled front wheel steering (two or three wheels), offering lightweight maneuverability and rapid movement. Widely used for patrol, passenger/cargo transport, and as sports equipment.
