What are the parking steps for an automatic transmission car?

Automatic transmission car parking steps are: 1. Press the brake and shift the gear to N; 2. Pull up the handbrake and shift to P; 3. Release the brake and turn the key to turn off the engine. Notes for shifting gears in automatic transmission cars: 1. Do not press the accelerator pedal when shifting gears; 2. Do not immediately press the accelerator pedal hard after shifting to a gear; 3. The vehicle can only be started in P or N gear; 4. The gear lever must be pressed with the brake when removing it from P gear; 5. Do not shift to N gear while driving; 6. Do not push into P gear while the car is moving; 7. When changing the direction of travel, switching between D and R gears must be done after the vehicle has come to a complete stop; 8. Placing the gear in N while driving prevents the oil pump from supplying oil normally for lubrication, which can cause the temperature of internal transmission components to rise and result in damage.

How is the compensation amount calculated for motor vehicle loss insurance?

There are two specific scenarios: 1. If the insured amount is higher than the actual value of the vehicle at the time of the incident, the compensation should be calculated based on the actual value at the time of the incident. The specific calculation formula is: Actual compensation amount = (Actual value at the time of the incident - Residual value) × (1 - Deductible rate). 2. If the insured vehicle suffers a total loss and the insured amount is equal to or lower than the actual value of the vehicle at the time of the incident, the compensation should be calculated based on the insured amount. The specific formula is: Actual compensation amount = (Insured amount - Residual value) × (1 - Deductible rate). Partial loss refers to local damage to the insured vehicle that does not reach the level of total destruction or presumed total loss. Compensation for partial loss is also divided into two scenarios: 1. For vehicles with the insured amount determined based on the new vehicle purchase price, the compensation should be calculated based on the actual repair costs and necessary, reasonable rescue expenses. The formula is: Compensation amount = (Actual repair and rescue costs - Residual value) × (1 - Deductible rate).

Can You Drive to a Repair Shop with a Flat Tire?

Tire pressure is too low, it is not advisable to continue driving; forcing the vehicle to move in this condition can lead to the tread being crushed, the wheel rim coming into contact with hard objects on the road, causing damage or deformation, and in severe cases, damaging the car's suspension. If you discover a flat tire while driving, you should immediately pull over to the side of the road, replace it with the spare tire, and then proceed to a repair shop as soon as possible to have the tire patched or replaced. Hazards of over-inflated tires: Reduced friction and adhesion of the tire, affecting braking performance, causing steering wheel vibration and deviation, decreased ride comfort, accelerated wear of the tread center pattern, increased risk of tire bulging and stone trapping, excessive stretching and deformation of tire cords, reduced tire elasticity, increased impact during driving, louder driving noise, and higher susceptibility to punctures from sharp objects like nails or glass on the road, which can lead to internal cracks and blowouts. Hazards of under-inflated tires: Increased friction coefficient with the road surface, higher fuel consumption, multiplied friction between the tire and the ground, rapid rise in tire temperature, softening of the tire, sharp decrease in strength, potential blowouts during high-speed driving, increased tire body deformation, prone to cracking on the sidewalls, flexing movements leading to excessive heat, accelerated rubber aging, fatigue of the cord layers, cord breakage, increased tire contact area, accelerated shoulder wear, heavier steering wheel, tendency to deviate, poorer handling, and louder tire noise.

What does the white exclamation mark on the BMW dashboard mean?

The white exclamation mark on the BMW dashboard is a normal fault indicator light. Common reasons for the fault indicator light to illuminate: Overheating of the power shift dry clutch, fuel cut-off system intervention or failure, parking sensor failure, external light failure, oil pressure sensor failure, warning or driving acceleration slip regulation failure. The appearance of an exclamation mark on the car dashboard indicates an abnormality or fault in the corresponding system. There are many indicator lights on the car dashboard with exclamation marks, such as tire pressure indicator light, lighting fault indicator light, steering system fault indicator light, brake system fault light, transmission fault indicator light, and wiper fault indicator light. The following is a detailed introduction to the exclamation mark fault light: General fault: A triangle with an exclamation mark inside. If this symbol lights up, it means that the car's general performance or components and functions have failed. Mainly includes parking sensor failure, fuel cut-off system intervention or failure, external light failure, engine oil pressure sensor failure, etc. You need to go to a 4S shop for inspection to find out the source of the fault. Automatic transmission fault: A yellow gear with an exclamation mark inside. This is the automatic transmission fault warning light, indicating that there is a fault in the transmission or the transmission lubricating oil is below the normal range. The transmission oil needs to be replaced in time. Brake system fault: A circle with parentheses and an exclamation mark in the middle. This represents a warning of the brake system, mainly including brake system failure and low brake fluid level. The brake system needs to be repaired immediately to avoid accidents. Tire pressure abnormality: A horizontal line with parentheses and an exclamation mark in the middle. This represents the tire pressure monitoring warning light. When the car's tire pressure is too low, this warning light will illuminate. You need to check the car's tire pressure and restore it to the normal range. Lighting fault: A yellow bulb with an exclamation mark. This is the lighting fault indicator light, indicating that a car light has failed. Solution: Go to a 4S shop for inspection and treatment as soon as possible, or you can check it yourself. Focus on checking commonly used bulbs such as turn signals, fog lights, and interior lights to find out where the problem is. In addition, during the daily use of the vehicle, the fault lights displayed on the vehicle dashboard will be divided into two different colors: yellow and red: Yellow indicates that there is a fault in the corresponding system, but the problem is not very serious. You need to slow down and proceed to the corresponding repair point for maintenance to eliminate potential safety hazards in time. Red indicates that there is a very serious problem in the corresponding system. If this happens, do not continue driving. You should pull over immediately and call for professional help to prevent unpredictable dangers to the vehicle and personal safety caused by forced driving. It should be noted that when the car is started, all lights will light up, and the system will perform an automatic test. After the test is completed, they will automatically go out. If a light does not light up when the ignition is turned on, or stays on and does not go out, or lights up while driving, it means that the related system has failed. In such cases, you should seek professional help in time to inspect the car and eliminate potential safety hazards.

What brand is the FAW-Volkswagen dedicated engine oil?

FAW-Volkswagen's original engine oil uses brands such as Shell and Castrol. The original engine oil options are as follows: Gray bucket D4-5W40 mineral oil, suitable for EA111, EA211, and MPI engines, not for TSI engines; White bucket Z4-5W40 semi-synthetic oil, suitable for TSI engines, EA888G2, EA888G3, EA211, EA111 full series SVW, TSI, MPI engines, the original engine uses this oil; Brown bucket premium 5W40 semi-synthetic oil, not for TSI engines, an upgrade of the gray bucket, suitable for EA111, EA211, and MPI engines; Gray bucket premium 5W30 full synthetic original oil, reportedly Valvoline oil repackaged, suitable for TSI, MPI, EA111, EA211, EA888G3 engines, with lower viscosity than the white bucket, not suitable for EA888-G2 series engines; Mobil 1 5W30 full synthetic oil, suitable for TSI, MPI, EA111, EA211 engines, with lower viscosity than the white bucket, not suitable for EA888-G2 series engines; Castrol Edge 5W30 full synthetic oil, suitable for TSI, MPI, EA111, EA211 engines, with lower viscosity than the white bucket, not suitable for EA888-G2 series engines. The viscosity of engine oil changes with temperature, so special attention is needed to its performance under low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity, with 5W representing the ability to withstand -30°C, where a smaller number means better low-temperature fluidity, making cold starts smoother. The latter number represents the kinematic viscosity at 100°C, with higher values indicating better viscosity retention at high temperatures, meaning better lubrication performance under high temperatures. The method for changing FAW-Volkswagen's engine oil is as follows: Wait for the engine temperature to drop and for the oil to flow back to the oil pan; Use a wrench to loosen the oil drain plug, collect the old oil in a pan until no more oil flows, then start the engine for 30 seconds to allow oil in the main oil passage to drain; Use a special wrench to remove the oil filter; Apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add new oil through the engine valve cover's oil filler, usually filling about three-quarters of the oil bucket; Start the engine and let it run for 5 minutes, checking for leaks at the oil drain plug and oil filter, and repair if necessary; After stopping the engine, pull out the oil dipstick to check if the engine oil level is within the standard range.
