How to Change the Transmission Oil for Lavida?

What does the SE light mean?

This is the maintenance indicator light of the car. When this light comes on, the owner must immediately go to the 4S shop for maintenance. Regular maintenance is crucial for the car. If the car is not maintained on time, it will affect the performance of the car. Maintenance mainly involves replacing the wearing parts and fluids. Extended information: 1. The wearing parts of the car include engine oil, transmission oil, coolant, differential oil, power steering oil, and brake oil. Engine oil is called the blood of the engine. If there is no engine oil in the engine, the engine cannot run normally. Engine oil not only lubricates the engine but also cleans, seals, buffers, prevents rust, and dissipates heat. 2. When the engine is running, the engine oil forms an oil film on the surface of each part of the engine, which can prevent direct contact and friction between the parts. If the parts directly contact and cause friction, it will increase the wear of the engine and also cause a large amount of heat to be generated instantly in the engine, which is a fatal risk for the engine.

Can an Electric Vehicle with Lead-Acid Battery Use Lithium Battery?

It is not advisable to replace a lithium battery with a lead-acid battery. For electric vehicles, it is best to use the original lithium battery or lead-acid charger that comes with the vehicle. Using mismatched chargers can cause significant damage to the battery and may also lead to safety hazards. Additional Information: 1. When replacing a lithium battery with a lead-acid battery, it is essential to ensure that the voltage remains the same as the original lithium battery. Additionally, the charger must be replaced with a dedicated lead-acid battery charger. Improper installation or poor-quality lead-acid batteries may damage the controller. 2. When replacing a lithium battery with a lead-acid battery, the size of the battery compartment must also be considered. Generally, lithium battery compartments are relatively small, while lead-acid batteries are larger. This factor must be carefully considered before replacement. If the gap is too small after installation, the battery may not fit. If you decide to proceed with the replacement, it is recommended to consult an electric vehicle repair shop and have it installed by professionals.

Should New Cars Undergo Crystal Coating?

It is necessary. Once a new car leaves the production line, its paint surface begins to react with the air and oxidize. Over time, the paint deteriorates and loses its luster. Applying crystal coating to a new car can slow down the oxidation of the car's paint surface and help maintain its glossy appearance. Below are the benefits of crystal coating: 1. Enhanced corrosion resistance: After crystal coating, the car's surface is isolated from the external environment, making it less susceptible to oxidation by air and effectively preventing acid rain from corroding the paint surface. This significantly extends the lifespan of the car's paint. 2. Easier cleaning: The car's surface becomes as smooth as ceramic tiles after crystal coating. During routine car washes, simply rinsing with water can easily remove dust, mud, and other debris from the surface. 3. Scratch resistance: Crystal coating reduces damage from external forces to the car's surface. Any scratches will only affect the crystal layer, not the car's paint or primer, preventing severe damage.

How is the SAIC dry dual-clutch transmission?

SAIC's dry dual-clutch technology is quite mature, but there are some minor issues. The SAIC dry dual-clutch transmission may experience severe overheating when frequently shifting between first and second gears in traffic jams. The driving techniques for dry dual-clutch transmissions are as follows: 1. Light throttle and gentle start: The gentle start is because the original design allows the dual-clutch to output maximum torque in second gear, while first gear lacks sufficient power. Therefore, you should wait until the throttle smoothly transitions to second gear before pressing the accelerator further. 2. Shift to neutral when parking: The principle of the dual-clutch is similar to that of a manual transmission. When parking, the clutch is not completely disengaged. Due to the purely mechanical connection principle, when the brake is pressed for a long time with the gear engaged, the energy has nowhere to go, causing some wear on the clutch disc.

How to Determine VVT Pulley Abnormal Noise?

Here are the inspection and handling steps for determining VVT pulley abnormal noise: 1. Abnormal noise occurs when the car is idling or running at low speed. Possible causes include excessive clearance between the piston and cylinder wall; overly tight piston pin or connecting rod bearing assembly; wear of the camshaft profile, etc. 2. Abnormal noise appears during rapid acceleration of the engine. Possible reasons may include loose connecting rod bearings, melted or mismatched bearing shells causing rotation; loose crankshaft bearings or melted bearing shells; broken piston pin; broken crankshaft. Extended information: 1. VVT (Variable Valve Timing) technology is used in automotive piston engines. It refers to controlling the advance and delay of intake valve angles under specific conditions to adjust the intake/exhaust volume and valve overlap angle, thereby increasing intake impulse and efficiency, and improving engine power, torque, etc. 2. If the engine VVT pulley is damaged and produces abnormal noise, the car will experience unstable engine idling and increased fuel consumption, which can also cause certain damage to the engine. Therefore, timely repair is necessary to avoid accidents.

How soon can traffic violations be checked?

Violations captured by traffic cameras will be notified within one week, while those issued with on-site tickets will be notified within 15 days. Under special circumstances, the notification period may be extended. The specific timeframes are as follows: Electronic monitoring violations: 48 hours (normally not exceeding 1 week); On-site violations: within 15 days. Below is relevant information about vehicle violation inquiries: Inquiry methods: You can log in to the external service websites of the Public Security Traffic Management Bureau of each city: locate the vehicle violation inquiry section, enter the license plate number and vehicle engine number, then click to inquire. You can also call the inquiry hotline, send a text message to check violations, or download mobile applications such as Wheel Violation Check for mobile users. Input your vehicle information to check violations in real time. Driving suggestions: Drivers should familiarize themselves with traffic regulations and regularly check their violation records online to avoid failing the annual vehicle inspection.
