What is the recommended tire pressure for 21-inch Cayenne tires?

First, check the manufacturer's recommended tire pressure, which is generally around 2.3 bar. Here is some relevant information: Seasonal factors: In winter, it is advisable to increase the standard tire pressure by approximately 0.2 bar. In summer, follow the lower limit of the standard tire pressure. If the car is parked outdoors in summer, the pressure can generally be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures. Load capacity: When the vehicle is empty, follow the lower limit of the standard tire pressure (the tire pressure indicated on the vehicle's sticker can serve as a reference for the minimum tire pressure). When fully loaded, follow the upper limit of the standard tire pressure (the maximum tire pressure indicated on the tire can serve as a reference for the theoretical maximum tire pressure). Tire pressure measurement environment: The tire pressure of a cold tire differs from that of a hot tire, so be mindful when measuring. The difference between the two is approximately 0.2 bar. Measure the tire pressure at least three hours after parking or if the tire has been driven for no more than 2 kilometers. If you can only measure the tire pressure when the tire is hot, subtract approximately 0.2 bar from the measured value to get the tire's cold inflation pressure.

Why Shift to a Lower Gear When Climbing a Slope?

1. Because the lower the gear, the greater the torque output from the drive wheels, resulting in greater traction. Here are the relevant explanations: 1. Climbing a slope: When going uphill, the car is subjected to downward gravity while also needing to overcome road resistance. 2. Power: If the gear is too high, the drive wheels will have insufficient power, naturally requiring the car to shift to a lower gear when climbing. 3. High gear: If the gear is too high, you should shift to a lower gear when climbing a slope. 2. Here are situations where D1, D2, and D3 can be used: 1. When climbing a slope: D1 and D2 can be used when going uphill, especially on steep slopes, manually setting the gear to first or second, similar to driving a manual transmission on a steep slope. Using a lower gear achieves greater torque, making it easier to climb the slope. 2. When overtaking: The advantage of D3 is faster response when overtaking. At a speed of 80 km/h, the gear is usually in 5th or 6th. If you want to overtake quickly, the automatic transmission will gradually shift down from 6th to 5th, then to 4th, and finally to 3rd, a process that takes time.

What's Inside a Used Car Archive Bag?

Used car archive bags contain the vehicle's records, including the vehicle inspection results, vehicle conformity certificate, vehicle invoice, purchase tax payment certificate, vehicle mortgage records, transfer records, and initial records. Each transaction adds a new record. Here are methods to check if a used car has been in an accident: 1. Check the glass production date: Normally, glass isn't replaced, so checking its production date can be revealing. The date is usually in the format of numbers + dots, where numbers represent the year and dots represent the month. 2. Examine the frame's wear: If the car was in a major accident, the frame would show dents or misalignment. 3. Inspect the screws: Look at the screws on the hood, radiator support, and doors. If any of these screws show abnormalities, it's likely the car was in a major accident. 4. Check maintenance records: Visit a 4S shop to review maintenance records. Any accident repairs done at a 4S shop would be systematically recorded.

Can a second-hand car be driven on the road if the insurance is not transferred after ownership transfer?

Compulsory traffic insurance allows driving on the road if it is still valid. It is recommended that the owner promptly completes the insurance transfer after the second-hand car ownership transfer. Otherwise, if the vehicle is involved in an accident, the insurance company has the right to refuse claims, and even if a claim is made, the cooperation of the original owner is required, making the process quite troublesome. Below is an introduction to vehicle insurance: 1. Compulsory Traffic Insurance: This is a mandatory insurance required by the state. If not purchased, traffic police can impose fines upon inspection. This insurance offers limited compensation, mainly covering others, and does not compensate for damage to the owner's own vehicle. 2. Third-party Liability Insurance: This is used to compensate for losses caused by the owner to third parties in terms of personal injury or death. This must be purchased as it provides protection for both the owner and others. 3. Vehicle Damage Insurance: This compensates for losses to the vehicle itself caused by natural disasters and accidents. It is recommended for new drivers. 4. No-deductible Insurance: An additional insurance that transfers the responsibility the owner would otherwise bear to the insurance company, reducing the owner's losses. If both Vehicle Damage Insurance and Third-party Liability Insurance are purchased, it is advisable to also purchase No-deductible Insurance.

What Does It Mean to Turn the Steering Wheel to Full Lock?

It means turning the steering wheel to its limit, where it can't turn any further. For example, turning fully to the left means rotating it all the way to the left, typically about two and a half turns. This is usually done when the vehicle needs to make a large turn, such as during a U-turn or a sharp corner. When turning the steering wheel, if the turn exceeds half a rotation, you should alternate your hands to complete the turn. The same applies when straightening the wheel—if it exceeds half a rotation, switch hands alternately to return it. Below is an introduction to the steering wheel: 1. Steering Wheel Overview: The steering wheel is a wheel-shaped device used to control the direction of cars, ships, airplanes, etc. 2. Steering Wheel Function: Its function is to convert the force applied by the driver on the edge of the wheel into torque, which is then transmitted to the steering shaft.

Can Gas Stations Refuel Generators?

Gas stations do not refuel generators. Generally, only vehicles can be refueled at gas stations. Vehicle owners can draw some fuel from their own tanks and add it themselves. A gas station is a service station for cars and other motor vehicles, retailing gasoline and engine oil, typically providing fuel oil, lubricants, etc. Here are some parking precautions: 1. No parking in areas with no-parking signs: No-parking signs indicate that within the specified range, all vehicles are prohibited from parking temporarily or for an extended period. 2. No parking within yellow grid lines: Yellow grid lines indicate that parking is prohibited in this area for any reason. They are commonly seen at intersections, entrances, and exits. 3. Yellow solid lines: Roads with yellow solid lines prohibit parking. The length of the yellow solid line indicates the size of the no-parking zone. 4. No parking near bus stops: Parking is prohibited in areas such as bus stops, gas stations, emergency stations, fire hydrants, etc.

Dare to Drive the Courtesy Car Provided by a 4S Store?

4S stores provide courtesy cars that can be driven, but in the event of a traffic accident, the responsible party must bear the liability. Article 19 of the "Regulations on the Repair, Replacement, and Return of Household Automotive Products" stipulates: During the warranty period of household automotive products, if the repair time (including waiting time for spare parts) exceeds 5 days due to quality issues, the consumer should be provided with a courtesy car or reasonable compensation for transportation expenses. Below is an introduction to 4S stores: 1. Introduction to 4S stores: A 4S store, fully known as an automobile sales service 4S store, is a car sales enterprise that integrates vehicle sales, spare parts, after-sales service, and information feedback. 2. Services of 4S stores: The core competitiveness of a 4S store lies in winning customers with high-quality services. At a 4S store, consumers can access all value-added services related to car information, market trends, after-sales service, maintenance guidelines, and spare parts supply. Whether for vehicles or parts, authenticity and quality are guaranteed, eliminating consumers' concerns about after-sales service, repairs, and maintenance.
