How to Modify the Registered Mobile Phone Number for Motor Vehicle Filing?

To modify the registered mobile phone number for motor vehicle filing, the vehicle owner needs to bring their original ID card. For company vehicles, the original organization code certificate, company seal, and the agent's original ID card are required. The modification must be done at the internet service window of the vehicle management office. Below is relevant information regarding the modification of the registered mobile phone number for motor vehicles: 1. Pay attention to the registration time: Some vehicle owners may have registered their phone numbers a long time ago, and the phone numbers registered for their driver's license or vehicle may no longer be in use but have not been updated at the vehicle management office in time. Even if they want to change the information on the "12123" app, they cannot register successfully if the phone number used for registration is not the one previously registered. 2. Update the registered phone number promptly: If the phone number used for registering the driver's license or vehicle was used to register for the traffic management app "12123", the owner can log in directly and make changes on the business hall page of the app. Failing to update the registered phone number promptly can have consequences. If the driver's mobile phone number or other information changes and is not updated at the vehicle management office in time, they may not receive SMS reminders, leading to overdue renewal or inspection of the driver's license. Exceeding the time limit may result in point deductions, fines, or even revocation of the driver's license, causing inconvenience to daily life and travel.

How Long Is the Break-in Period for New Drivers?

New drivers should observe a break-in period of approximately 1,000 kilometers. Here are some tips to extend your vehicle's lifespan: 1. Avoid emergency braking: Emergency braking not only shocks the braking system during break-in but also increases impact loads on the chassis and engine. Therefore, it's recommended to avoid emergency braking within the first 300 kilometers of driving. 2. Don't overload the vehicle: Overloading a new car during break-in can damage mechanical components. During the first 1,000 kilometers, keep the load below 75%-80% of the rated capacity. 3. Minimize long-distance trips: Overloading a new car during break-in can damage mechanical components. During the first 1,000 kilometers, keep the load below 75%-80% of the rated capacity. 4. Avoid high-speed driving: New drivers should prioritize stability over speed. There are speed limits during break-in: domestic cars should stay between 40-70 km/h, while imported cars should stay below 100 km/h. When fully accelerating, speed shouldn't exceed 80% of maximum speed. Monitor the tachometer and speedometer to maintain moderate engine speeds. Typically, keep engine RPM between 2,000-4,000 during break-in. If these numbers are hard to remember, maintaining a steady 60 km/h is always safe.

What Causes the RPM Gauge to Fluctuate While Driving?

Here are the reasons why the RPM fluctuates while driving: 1. Charging circuit malfunction: The charging circuit issue could be caused by a faulty alternator, battery voltage sensor failure, or loose battery terminals. While driving, the alternator needs to charge the battery. If the battery fails to charge or receives insufficient charge, the engine ECU will increase the engine RPM to allow the alternator to charge the battery, resulting in fluctuating RPM readings. 2. Throttle malfunction: Throttle issues may stem from a faulty throttle position sensor or throttle control motor. The throttle position sensor detects the throttle opening to regulate fuel injection, while the throttle control motor adjusts the throttle angle based on accelerator pedal input. If these components fail, the engine's air intake changes, causing the RPM gauge to fluctuate. 3. PCV valve or charcoal canister solenoid valve failure: The PCV (Positive Crankcase Ventilation) valve recirculates combustible gases from the crankcase back into the intake manifold for combustion. The charcoal canister solenoid valve directs fuel vapors from the fuel tank to the intake manifold. When these valves malfunction, the fuel mixture entering the cylinders deviates from the ECU's settings, leading to RPM fluctuations. 4. Engine carbon buildup: Carbon deposits in the throttle body and combustion chamber severely affect air-fuel mixture combustion. Throttle carbon buildup restricts airflow, while combustion chamber deposits interfere with fuel injection and ignition, potentially causing pre-ignition or knocking. This results in unstable engine RPM.

How to Use a Car Charger?

Instructions for using a car charger: Prepare the car charger, with the bottom of the car charger being the positive pole and the contacts on both sides being the negative poles. Insert the bottom of the car charger directly into the cigarette lighter and secure it. When inserted correctly, the LED indicator on the cigarette lighter will light up, and you can then connect a USB charging cable to charge your phone as usual. Note: For safety, remove the car charger promptly after charging. Principle of the car charger: It converts the 12-volt voltage from the car's cigarette lighter socket into a 5-volt USB voltage and charges electronic devices via the charging cable. Precautions for using a car charger: 1. Avoid throwing, dropping, hitting, or vibrating the charger during use. Especially in summer when the car is exposed to the sun and the interior temperature exceeds 45 degrees Celsius, temporarily stop using the charger, as this can severely damage the internal circuit board of the car charger. 2. A car charger is an electronic device. Owners should avoid leaving it in a humid environment for extended periods to prevent corrosion or oxidation of its internal electronic components. When charging an electric vehicle, try to do so outdoors with good ventilation and heat dissipation conditions to avoid overheating the charger. If water is accidentally spilled on the charger while driving, remove and dry it immediately. 3. After turning off the vehicle, remove the car charger and store it. If left plugged into the power interface for a long time, the contact parts may corrode and become difficult to clean. Also, continuing to use the cigarette lighter for charging after the car is turned off may drain the battery. Although 80% of cars cut off power to the cigarette lighter after removing the key, the cigarette lighter will draw power directly from the battery after the engine stops supplying power. If the car charger's power consumption exceeds the battery's capacity, the battery can easily be depleted.

What is the maintenance interval for BMW?

BMW's maintenance interval is 5,000KM for the first service, followed by a service every 10,000KM. Details of the mileage that can still be driven after the maintenance period are as follows: 1. Primary maintenance: Approximately 5,000 kilometers, focusing on tightening and lubricating components for vehicles that have traveled a certain distance. Includes inspecting and tightening bolts and nuts on the exterior of the vehicle; lubricating specified parts; checking and topping up oil levels in various assemblies; cleaning air filters, etc. The goal is to maintain the vehicle's optimal technical condition and ensure smooth operation. 2. Secondary maintenance: Approximately 10,000 kilometers, focusing on inspection and adjustment for vehicles that have traveled a certain distance. In addition to primary maintenance tasks, it involves checking and adjusting the engine and electrical equipment, dismantling and cleaning the oil pan and oil filter, inspecting and adjusting steering and braking mechanisms, and dismantling and cleaning front and rear wheel hub bearings. Lubricant is added, tires are dismantled and inspected, and rotation is performed. The aim is to ensure all components, mechanisms, and assemblies maintain good working performance and operate normally between two secondary maintenance periods. 3. Tertiary maintenance: Approximately 20,000 kilometers, focusing on disassembly, cleaning, inspection, adjustment, and hazard elimination for vehicle assemblies. In addition to primary and secondary maintenance tasks, it involves dismantling and inspecting the engine to remove carbon deposits, gum, and cooling system contaminants; dismantling, cleaning, inspecting, and adjusting the chassis assembly to eliminate hazards; inspecting the frame and body for rust removal and touch-up painting.

Can ETC vehicles use manual lanes when exiting the highway?

ETC vehicles can use manual lanes when exiting the highway. When entering the highway, the ETC system records the vehicle's information. Upon exiting, the system deducts the fee based on the recorded data. If the vehicle enters a manual lane, the driver can remove the ETC card and hand it to the staff for manual scanning, which still allows the information to be read and the fee deducted, after which the barrier will lift for normal passage. ETC (Electronic Toll Collection) is a non-stop electronic toll collection system, also known as an automatic road tolling system. It is specifically designed for toll roads, commonly found on highways, toll bridges or tunnels, and certain urban sections to alleviate traffic congestion. ETC Deduction Principle: Highways have one or more ETC lanes. Communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane enables backend settlement with banks via computer networking technology. This allows vehicles to pay tolls without stopping at toll booths, operating on a "pass first, deduct later" principle. Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues. Green and eco-friendly: Reduces noise and exhaust emissions by enabling non-stop passage through toll booths. Cost and wear reduction: Lowers fuel consumption and wear by reducing frequent starts and stops. Improved efficiency: ETC lanes theoretically increase vehicle throughput by 2-3 times, making traditional ETC faster and more advanced. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council's "13th Five-Year Plan for the Development of a Modern Integrated Transportation System" explicitly states goals such as achieving interoperability of transportation cards in key city clusters by 2020 and significantly increasing ETC adoption rates, targeting 50% ETC usage for road passenger vehicles by 2020. Future possibilities: Beyond improving ETC installation convenience and passenger vehicle usage, future efforts will promote ETC adoption for trucks and explore deeper integration with smart transportation initiatives like vehicle-to-vehicle communication and vehicle-infrastructure coordination, offering comprehensive travel services and expanding ETC application scenarios. ETC Usage Notes: The ETC transaction sensing range is 8 meters. To avoid mistakenly paying for the vehicle ahead (due to ETC device failure or absence), maintain a distance of over 10 meters. The ETC lane recognition speed limit is 20 km/h. Exceeding this speed may result in failed fee deductions. Unauthorized removal or movement of the OBU device, or loosening/detachment of the ETC tag, will deactivate the tag. Non-deliberate cases can be reactivated after inspection at the issuing bank or highway service center. Insufficient balance on debit cards linked to ETC may cause deduction failures. Follow staff guidance to use manual MTC lanes with cash or card payments. Thick or replaced windshields (e.g., after accidents or modifications) may impair ETC signal reception. ETC Working Principle: Via short-range communication between the vehicle's windshield-mounted electronic tag and the toll station's microwave antenna, backend banking settlement is processed through computer networking, enabling toll payment without stopping at highway or bridge toll booths. Benefits of Installing ETC: Saves time by eliminating queues. Reduces pollution via non-stop passage, lowering noise and emissions. Cuts costs by minimizing frequent starts/stops, reducing wear and fuel consumption. Boosts efficiency with 2-3 times higher lane throughput, offering more advanced technology than license plate payment.
