Multiple ignition attempts will lock the engine, also known as engine immobilizer. Classification of anti-theft system indicator lights: Anti-theft indicator lights are divided into original vehicle anti-theft indicators and aftermarket anti-theft device indicators. Function of anti-theft system indicator light: After pressing the lock button on the smart key, the car's anti-theft system activates, and the anti-theft light flashes to remind the owner that the vehicle's anti-theft system is activated and the vehicle is in armed state. Common icons on car dashboards: Door warning, handbrake warning, seatbelt warning, engine self-check, lubricant condition check, ABS system check, airbag check, battery warning and fuel level warning.

Are There Any Issues with Purchasing Stock Vehicles?

Purchasing stock vehicles is not problematic, but when buying vehicles that have been stored for an extended period, it is essential to carefully inspect the vehicle's condition. Engine oil and coolant need to be replaced, and it is also necessary to check for signs of weathering on the tires and wiper blades, whether the car's paint has oxidized, if the sealing strips and wiring harnesses have aged or cracked, if the battery is functioning normally, if various fluids need replacement, and if there are any oil leaks or damage to the chassis. Methods to Identify Stock Vehicles: Simply open the engine hood or the driver's side door to see the manufacturer's labeled vehicle model and production date, among other relevant information. The condition of a stock vehicle is not solely determined by the storage duration but more importantly by the dealer's storage environment and regular maintenance.

Should You Release the Throttle or Pull the Clutch First When Shifting Gears on a Motorcycle?

Whether to release the throttle or pull the clutch first when shifting gears on a motorcycle depends on the situation: When shifting from a lower gear to a higher gear, first close the throttle and then pull the clutch. When shifting from a higher gear to a lower gear, first pull the clutch and then close the throttle. Shifting from a low gear to a high gear: First accelerate, then reduce the throttle, quickly pull the clutch lever with your left hand to disengage the clutch, shift to the next higher gear, gently release the clutch lever, and then increase the throttle. Following these steps will allow you to gradually shift up to the highest speed gear. The key steps for shifting from a high gear to a low gear: First reduce the throttle to lower the speed, quickly pull the clutch lever, shift to the desired gear, then gradually release the clutch lever while increasing the throttle. When shifting from a high gear to a low gear, you must ensure the speed drops to match the speed range of the lower gear before shifting.

How Long Does It Take to Break in Newly Replaced Spark Plugs?

The normal break-in period is within 3,000 km, which typically takes about two months to reach under normal driving conditions. Spark plugs are critical components of a gasoline engine's ignition system. They introduce high voltage into the combustion chamber, creating a spark across the electrode gap to ignite the air-fuel mixture in the cylinder. Under high voltage, the air between the spark plug's center electrode and side electrode rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties and forming a discharge channel, resulting in a "breakdown" phenomenon. At this point, the gas becomes a luminous body, known as a "spark." Along with thermal expansion, a "crackling" sound is also produced. The temperature of this electric spark can reach 2,000–3,000°C, sufficient to ignite the air-fuel mixture in the cylinder's combustion chamber.

What procedures are required for selling imported cars?

Selling imported cars requires procedures such as transaction documentation, vehicle external inspection, license plate selection, and transfer deregistration. The associated costs are closely related to the vehicle's transaction price. Detailed introduction of relevant procedures: Transaction documentation: Pay the used car transaction tax. Private accounts are charged 1%, while corporate accounts are charged 3%. Vehicle external inspection: Drive the vehicle to the inspection station for external inspection, engine number tracing, license plate removal, and photography. Obtain vehicle photos and attach them to the inspection record form, then proceed to the transfer hall to complete the archiving procedures. License plate selection: After obtaining a number from the dispenser, queue with relevant materials to pay the transfer fees. Notes for selling imported cars: Parallel import vehicle general distributors will purchase a commercial after-sales triple warranty insurance for the vehicle, with consumers only needing to bear a small portion of this cost. Imported cars registered and filed at 4S dealerships have varying after-sales services depending on the brand, with specific details outlined in the warranty card.
