Open the driver's door, engage the Porsche Cayenne's handbrake to prevent the vehicle from rolling, pull the fuel tank cap switch located on the left side of the driver's leg area, lift the Porsche Cayenne's fuel tank cap outward, and unscrew the plastic cap of the fuel tank. Precautions for cleaning the fuel tank are as follows: 1. Note 1: After using the car for a period of time, perform a thorough cleaning and inspection of the fuel tank. When cleaning the fuel tank, rinse the interior with hot water, then dry it with compressed air to remove gasoline vapors inside the fuel tank. 2. Note 2: Then immerse the fuel tank in a 10% sodium hydroxide aqueous solution for cleaning. After soaking, rinse the interior and exterior of the fuel tank with running water. Alternatively, you can clean it with a 5% boiling caustic soda solution, followed by rinsing with hot water. 3. Note 3: If there is rust on the exterior of the fuel tank, clean it with a steel wire brush and then apply paint. After cleaning the fuel tank, perform a leak test by sealing all openings with rubber plugs and submerging the tank in water. Introduce compressed air through the fuel pipe connector hole. If bubbles emerge from any part, it indicates a leak. Mark the leak, remove the paint, and weld the area.

What are the size and interface type of the Volkswagen Santana wiper blades?

The Volkswagen Santana wiper blades are sized at 24+16 inches and use a U-shaped interface. There is no fixed replacement cycle, but they should be promptly repaired or replaced if there is abnormal noise or poor wiping performance. The steps to replace the Volkswagen Santana wiper blades are as follows: 1. After turning off the vehicle, do not remove the key. Within 3 seconds, pull the wiper control lever inward, and the wipers will stop in the maintenance position. 2. Push the wiper blade in the direction of the front of the vehicle until it locks into a specific position. Press the button on the wiper blade downward while shaking and pulling the blade upward to successfully remove the old rubber strip. 3. Release the two securing clips and remove the original rubber strip. (When removing the middle connecting device and the clips on both sides, be mindful of the force applied—the plastic ends on both sides should not be detached.) 4. Once the new rubber strip is successfully installed, follow the reverse order of the disassembly steps to reinstall the wiper blade.

How to Replace the Transmission Oil for a New Sail?

New Sail transmission oil replacement method is as follows: 1. First, unscrew the drain plug and fill plug of the transmission to completely drain the old gear oil. 2. Then, add the prepared oil through the fill tube. More information about transmission oil: 1. Regularly check whether the automatic transmission fluid level is normal. The transmission oil needs to be preheated to about 50°C, then shift the gear lever through each position for 2 seconds before placing it in park. 2. Vehicle transmissions are roughly divided into manual transmissions, manual-automatic transmissions, CVT transmissions, and dual-clutch transmissions. No matter what type of transmission, its fluid has a service life.

What does 'TC' mean when displayed on a Buick sedan?

When 'TC' is displayed on a Buick car, it indicates a malfunction in the Traction Control System. In such cases, it is advisable to visit a Buick 4S dealership to have a technician read the fault codes, identify the cause and location of the fault, and proceed with immediate repairs. More information about the Traction Control System is as follows: 1. The Traction Control System is a driving assistance system in vehicles that controls the power to the drive wheels. 2. The Traction Control System only activates when the drive wheels slip. If the drive wheels slip, the system will limit the engine's power output and apply brakes to the slipping drive wheels, thereby preventing excessive wheel slip.

When Can You Turn on the Heater After Starting the Car?

You need to wait until the engine's coolant temperature reaches the standard level before turning on the heater after starting the car. This usually takes about five to ten minutes. More details are as follows: 1. Do not turn on the heater immediately after entering the car. Wait until the car is started and the coolant temperature reaches the normal level. 2. The car's heating system relies on the engine, especially in winter. If the car is started cold, the engine temperature is very low. Turning on the heater before the engine warms up will not only blow out cold air but also hinder the engine's temperature rise. 3. If the engine's coolant temperature hasn't risen, the low temperature can reduce the performance of the engine and other components, increasing the car's driving burden and naturally raising fuel consumption. 4. Most cars today use a water-based heating system, while some high-end models combine water heating with a PTC heater. The heater temperature should not be too high; around 20°C is the most comfortable for the human body.

What to Do When the Service Brake Fails While Driving Downhill?

When driving downhill, if the service brake (foot brake) fails, you can use engine braking to slow the vehicle down to a stop. In emergency situations, you can also bring the car to a halt by scraping against roadside obstacles to prevent more serious accidents. More details are as follows: 1. If the service brake fails, you can use the parking brake. It is best to use engine braking when going downhill. Parking brake braking refers to stopping the car using the handbrake. Here, it does not necessarily mean pulling the handbrake all the way; you can also slowly apply the handbrake to decelerate appropriately. 2. Engine braking involves lifting the accelerator pedal without depressing the clutch, utilizing the compression resistance, internal friction, and intake/exhaust resistance generated by the engine's compression stroke to create a braking effect on the drive wheels. Engine braking uses the engine's drag effect to slow the vehicle. The lower the gear, the more noticeable the drag effect and the stronger the braking. 3. When driving on long downhill roads, shifting to a lower gear and using the engine's drag effect can reduce the burden on the brakes and minimize the number of brake applications, preventing brake overheating and subsequent thermal fade. When driving on icy, snowy, or muddy roads, using engine drag braking can help prevent skidding.
