What Does the Exemption Clause in the Three Guarantees for Imported Cars Mean?

Import car three guarantees exemption refers to a waiver agreement where dealers require car owners to relinquish their right to claim compensation when quality issues arise with the vehicle. Currently, parallel imported cars mainly fall into two categories: narrowly defined parallel imported cars and modified cars (also known as large trade cars). According to national regulations, narrowly defined parallel imported cars are subject to the three guarantees and recall responsibilities borne by the importer. Key provisions in the automobile three guarantees policy that consumers should be aware of include: 1. Unauthorized modifications to the vehicle are prohibited. The automobile three guarantees policy stipulates that if the user manual explicitly states that modifications, adjustments, or disassembly are not allowed, and the consumer performs such actions resulting in damage, the dealer may not be held responsible under the three guarantees. 2. Maintenance must be performed at designated service stations. The automobile three guarantees policy also states that if the consumer fails to use, maintain, or repair the product correctly as required by the user manual, resulting in damage, the dealer may not be held responsible under the three guarantees. 3. The warranty period for household automobiles shall not be less than 3 years or 60,000 kilometers, whichever comes first. The three guarantees validity period for household automobiles shall not be less than 2 years or 50,000 kilometers, whichever comes first. The warranty period and three guarantees validity period for household automobiles are calculated from the date the seller issues the purchase invoice.

Is the engine of the Honda URV370 an Earth Dreams engine?

The engine of the Honda URV370 is an Earth Dreams engine, which is a type of engine produced by Honda. This engine is manufactured domestically. The engine model used in the Honda URV370 is the Earth Dreams K20C3, with a maximum horsepower of 272 HP, a maximum power output of 200 KW, a maximum power speed of 6500 rpm, and a peak torque of 370 N.m. For daily maintenance of the Honda URV370's engine, the following methods can be used: Use lubricating oil of the appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional equipment of the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, with the selection standard not lower than the manufacturer's specified requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, leading to various engine issues. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and sticky substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication area, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal particles from component wear to form sludge. Small amounts remain suspended in the oil, while larger amounts precipitate, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures the engine operates properly but also extends the overall lifespan of the radiator and engine.

How to Open the Porsche Sunroof?

Porsche sunroof opening method: By long-pressing or short-pressing, the sunroof can be opened to the desired position or fully opened; pressing the switch upward can tilt the sunroof; approximately 10 minutes after turning off the ignition switch, the sunroof and sunshade can still be opened or closed. The car sunroof is installed on the roof, effectively promoting air circulation inside the vehicle, allowing fresh air to enter, and providing the owner with a healthy and comfortable experience. At the same time, the car sunroof can also broaden the view and is often used for mobile photography and videography needs. Advantages of car sunroofs: 1. Cooling: Utilizing the negative pressure formed on the roof during vehicle movement to extract hot air can achieve rapid air exchange and cooling. This method is 2-3 times faster than using the car air conditioning for cooling; 2. Air exchange: When the car is driving at high speed, air flows rapidly around the vehicle. When the sunroof is opened, a negative pressure area forms outside the car. Due to the difference in air pressure inside and outside the car, the polluted air inside can be extracted, achieving the purpose of air exchange and keeping the cabin filled with fresh air; 3. Auxiliary defogging: If the side windows are tightly closed during driving, the temperature difference inside and outside the car increases, making the front windshield prone to fogging. Although most cars are equipped with anti-fog devices, some are not very effective. Drivers only need to open the sunroof to the rear-tilt ventilation position to easily eliminate fogging on the front windshield, ensuring driving safety; 4. Escape route: In the event of a traffic accident, if the doors are squeezed and deformed and cannot be opened, as long as it is not a rollover accident, the sunroof can serve as an effective escape route. News reports such as 'a driver drove into a river due to improper operation and finally escaped through the sunroof' can be seen, which should be described as 'being prepared for any eventuality.'

How to Overtake?

Before overtaking, always observe the condition of the lane you intend to use and the driving situation of the vehicles ahead of the car you want to overtake. Reduce your own speed. Turn on the turn signal of the lane you intend to use to signal your intention to overtake. Avoid continuous lane changes during the overtaking process. After completing the lane change, accelerate in a straight line, observe the rear to ensure safety, and then return to the original lane.

How to Determine if Wheels are Interchangeable?

Tire types have international standard tire codes, expressed in millimeters to indicate the section width and the percentage of the aspect ratio. Under the same size conditions, different categories may still vary. In such cases, it is necessary to compare the number of bolts to determine if they match. If the bolt pattern matches, it generally means the wheels are compatible.

Audi Q5 Sunshade Matching Method

Insert the vehicle key into the ignition slot to power on the vehicle; otherwise, the sunroof cannot be matched. Locate the sunroof control knob on the vehicle's roof to initiate the matching process. Rotate the sunroof control knob clockwise to its maximum position. Press and hold the button indicated on the sunroof knob for five seconds, then release it upon hearing a beep.
