Location of the air conditioning relay in a Volkswagen Passat 1.8L: It is situated in the fuse box within the vehicle's engine compartment. On the box cover, there is a square position labeled A/C, which indicates the air conditioning relay. Below is relevant information about the air conditioning relay: 1. Function: A relay is an automatic switching component with isolation functionality, serving as an "automatic switch" that uses small currents to control the operation of larger currents. Therefore, it plays roles in automatic regulation, safety protection, and circuit conversion within electrical circuits. 2. Working principle: A relay is an electrical device that gradually alters the control quantity in a circuit when changes in the input quantity meet specified requirements. It interacts between the control system and the controlled system (also referred to as the output circuit).

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.

What Are the Impacts of Power Rationing on New Energy Vehicles?

New energy vehicle production has not been affected by power rationing. Detailed explanation on why new energy vehicles are not affected by power rationing: Economic Observer reporters reached out to multiple automakers including FAW-Volkswagen, JAC, BYD, Geely, NIO, and Li Auto. Most automakers responded that vehicle production has not been affected, though some suppliers have been impacted. Supplementary explanation on power supply and new energy vehicles: Regarding the current power supply shortage, the China Passenger Car Association pointed out that the electricity consumption of electric vehicles currently has no significant impact on the national power system. In the future, as the functions of electric vehicle batteries in power storage and regulating grid peak and off-peak become more prominent, electric vehicles will make greater contributions to the green development of society.
