Can Auto Start-Stop Be Permanently Disabled?

The engine start-stop function can be manually turned off via a switch in the car. However, it cannot be permanently disabled; it needs to be manually switched off each time the vehicle is started. Below is more information about the engine start-stop technology: 1. Engine start-stop technology automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) during driving. When it's time to move again, the system automatically restarts the engine. 2. The working principle of the start-stop system is that when the vehicle stops moving due to traffic congestion or at an intersection, the driver presses the brake pedal and shifts to neutral. Additional content: Below are the steps to disable the auto start-stop function: 1. The driver presses the brake pedal and shifts to neutral. 2. The Start/Stop system automatically detects: the engine is idling and not in gear. 3. The wheel speed sensors of the anti-lock braking system show zero. 4. The electronic battery sensor indicates there is enough energy for the next start. 5. Once these three conditions are met, the engine automatically stops.

How many kilometers should a new car drive before replacing the spark plugs?

Under normal maintenance conditions, a new car should have its spark plugs replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the instructions in the user manual for replacement. Maintenance replacement can be based on the following standards: Replace platinum spark plugs at 40,000 kilometers, replace ordinary nickel alloy spark plugs at 20,000 kilometers, and replace iridium spark plugs at 60,000 to 80,000 kilometers. Damaged spark plugs may exhibit the following symptoms: difficulty starting, reduced power, excessive exhaust emissions, and increased fuel consumption. If these symptoms occur, the spark plugs should also be replaced. Steps for replacing spark plugs: Open the engine hood, lift the plastic cover of the engine, remove the high-voltage branch lines, and mark each cylinder's position to avoid confusion. Remove the spark plugs one by one using a spark plug socket. During removal, check for any leaves, dust, or debris on the outside and ensure they are thoroughly cleaned. Insert the new spark plugs into the spark plug holes, rotate them a few times by hand, and then tighten them with the socket. Reinstall the removed high-voltage branch lines in the firing order and secure the cover plate.

What are the main maintenance items for a car?

The main maintenance items for a car include checking and replacing the engine oil, oil filter, fuel filter, air filter, cabin air filter, as well as inspecting and maintaining related systems such as spark plugs, transmission, throttle body, etc. The details of these maintenance items are as follows: 1. Engine oil and oil filter: Inspect and maintain the lubrication system to prevent excessive wear of components caused by deteriorated, insufficient, or contaminated oil. The oil filter should be replaced together with the engine oil. 2. Fuel filter: Maintain the fuel supply system to prevent clogged fuel lines due to excessive impurities, which may result in insufficient engine power or stalling. 3. Air filter: Maintain the intake system to prevent dust and impurities from entering the cylinders, which could cause wear in the compression system. The air filter should be cleaned regularly. 4. Cabin air filter: Inspect the cabin air filter to prevent excessive dust accumulation. If dust enters the evaporator, it may lead to insufficient cooling or malfunction of the air conditioning system. If the dust on the filter is not cleaned for a long time, it may produce odors and pollute the air inside the car. 5. Spark plugs: Maintain the ignition system to prevent excessive carbon buildup on the spark plugs, which could cause misfires, electrode leakage, or failure to spark, making the car unable to start. 6. Transmission: Check the transmission gear oil to prevent severe gear wear or breakage, which may cause abnormal noises, gear jumping, or sticking in the transmission. 7. Throttle body: Since the air filter may not completely remove impurities, the throttle body can easily become dirty. If the throttle plate is dirty, it may cause unstable idling, so it needs to be cleaned thoroughly. 8. Other components such as brake fluid, battery, fuel injectors, and brake pads should also be maintained to keep the car in good condition and prevent malfunctions while driving.

What Type of Engine Oil is Suitable for Volkswagen Santana?

Volkswagen Santana uses Volkswagen's original engine oil, with the oil model being 5w40, which is synthetic oil. If you wish to change the oil during later maintenance, you can choose international brands such as Shell, Mobil, or Castrol, or domestic brands like Great Wall, Tongyi, or Kunlun. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity, where 5W represents the ability to withstand -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother for the car. The latter number represents the kinematic viscosity of the oil at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in a Volkswagen Santana is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine for about 30 seconds to allow the oil in the main oil passage to drain; Use a specialized wrench to remove the oil filter; Apply oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add the new oil through the filler cap on the engine's valve cover, typically filling up to three-quarters of the oil container; Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. If leaks are found, repairs should be made; After stopping the engine, pull out the oil dipstick to check if the engine oil level is within the standard range.
