In summer, the normal tire pressure range is between 2.3 and 2.5. If the car is fully loaded with 5 passengers, it's recommended to adjust the tire pressure to around 2.5; for general use with two passengers, a tire pressure of 2.3 is normal. Hazards of overinflated tires: Reduced tire friction and adhesion, affecting braking performance; Causes steering wheel vibration and deviation, reducing driving comfort; Accelerates wear on the central tread pattern, shortening tire lifespan; Increases vehicle vibration, indirectly affecting the lifespan of other components; Overstretches tire cords, reducing elasticity and increasing load during driving; Decreases puncture resistance. Sharp objects like nails or glass can easily penetrate, causing internal cracks or blowouts. Hazards of underinflated tires: Increases friction with the road surface, leading to higher fuel consumption; Causes heavy steering and deviation, compromising driving safety; Increases movement of tire components, causing abnormal heat from excessive rolling; Reduces cord and rubber functionality, leading to delamination or cord breakage and excessive friction with the rim, causing bead damage and abnormal wear; Multiplies friction with the ground, rapidly increasing tire temperature, softening the tire, and drastically reducing strength. High-speed driving may cause blowouts; Increases tire deformation, causing sidewall cracks and flexing movements that generate excessive heat, accelerating rubber aging, cord fatigue, and breakage, while also increasing contact area and accelerating shoulder wear.

What is the license plate registration process at a 4S dealership?

The license plate registration process at a 4S dealership is as follows: 1. Bring your ID card, residence permit, vehicle certificate, and invoice, and pay the vehicle purchase tax; 2. Register and inspect the vehicle at the vehicle management office; 3. Select a vehicle license plate number; 4. After choosing the number, pay the fee and wait for the license plate, which usually takes three to five working days to receive. License plates, commonly known as tags, refer to vehicle registration plates, which are plates hung on the front and rear of the vehicle. They are typically made of aluminum, iron, plastic, or paper, and display the vehicle's registration number, registration region, and other relevant information. License plates serve as identification and information registration for vehicles, allowing authorities to identify the vehicle's region of registration and trace the owner and registration details of the vehicle through the plate number.

What are the precautions when changing car engine oil?

Precautions when changing car engine oil are: 1. Perform the operation when the engine is warm to ensure the old oil is drained as completely as possible; 2. Add the new oil and ensure the amount is appropriate; 3. After adding the oil, start the engine and check all components for any leaks. Run the engine for 3 minutes to confirm the oil level reaches the normal mark. Engine oil, also known as engine lubricant, serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and cushion shocks. The steps for changing engine oil are: 1. Lift the car, remove the undercover, and place a container of about 10 liters under the oil drain plug; 2. Unscrew the drain plug, use an air gun to blow into the oil filler port for two minutes, then tighten the drain plug and wipe it with a paper towel to check for leaks; 3. Reinstall the undercover, lower the car, and use a funnel to add the new oil through the filler port.

How much oil should be added to a Jetta car?

Jetta cars require 4 liters of oil, and 5W40 or higher grade oil is suitable. The amount of oil to be added varies depending on the level of emissions. Engine oil serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. Taking the Jetta VS5 as an example, it is positioned as a compact car with body dimensions of 4419mm in length, 1841mm in width, and 1616mm in height, with a wheelbase of 2630mm. In terms of power, the Jetta VS5 uses Volkswagen's 1.4T turbocharged engine, model EA211DJS, with a maximum power of 110kW and a maximum torque of 250Nm.

Why does the car still not start after jump-starting?

Jump-starting still failing to start the car is usually due to the battery being severely depleted or insufficient charging time. You can let the rescue vehicle run for a while, wait about 10 minutes, and then attempt to start the depleted vehicle. If successful, keep the depleted vehicle running for about 30 minutes to allow the alternator to charge the battery. If it still doesn't start, consider a possible starter motor failure. When performing a jump-start, it is recommended to use dedicated automotive jumper cables, avoiding makeshift or low-quality cables. Follow the correct connection sequence: connect the positive terminal first, then the negative. Ensure the clamps of the positive and negative cables do not touch each other, and the positive clamp does not contact any metal parts of the vehicle.
