BMW ignition brake cannot be pressed down due to problems with the brake hydraulic system, causing excessive pressure; the newly replaced brake discs have not been adjusted, resulting in the inability to press down. Brake hydraulic system failure: The car's vacuum booster pump leaks or malfunctions. The force applied to the brake pedal is amplified by the brake booster pump. If it fails, the brake loses its assist, making it difficult to press down. Newly replaced brake discs: New brake pads require a break-in period of 200 kilometers to achieve optimal braking performance. Therefore, it is recommended to drive cautiously after replacing new brake pads.

Why does an automatic transmission car roll back when starting on a slope?

An automatic transmission car may roll back when starting on a slope due to insufficient idle speed. Detailed explanation of why an automatic transmission car rolls back when starting on a slope: If an automatic transmission car rolls back when starting on a slope, or if it stalls when only in D gear without giving throttle on a slope, it is likely because the idle speed is insufficient and cannot propel the car to start on the slope. Precautions for automatic transmission cars rolling back when starting on a slope: If the car rolls back, the only solution is to press the brake, engage the clutch, and restart the car after it has come to a complete stop. Other than this, any attempts to correct the situation during the rollback are generally ineffective.

What kind of engine oil should be used for Nissan Sylphy?

For Nissan Sylphy, the best choice is the original 5W30 engine oil. If you want to change the oil during later maintenance, you can choose from brands such as Shell and Castrol. 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. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, making cold starts smoother. The latter number represents the kinematic viscosity of the oil at 100°C. The higher the number, the better the oil maintains its viscosity index 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 Nissan Sylphy is as follows: Wait for the engine temperature to drop and allow the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan underneath to catch the old oil until it stops flowing. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out; Use a special wrench to remove the oil filter; Apply some oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the oil filler cap on the engine valve cover. Generally, about three-quarters of a bottle is sufficient; Start the engine and let it run for 5 minutes, then check for any leaks around the oil drain plug and oil filter. If there are leaks, perform necessary repairs; After stopping the engine, pull out the oil dipstick and check that the engine oil level is within the standard range.
