How Often Should a Car Be Started If Not Driven for a Long Time?

If a car is not driven for a long time, it should be started approximately once a week. The reasons are as follows: 1. When the car is not used for an extended period, the lubricating oil will flow back to the oil pan due to gravity, reducing the lubrication effect on various moving parts; 2. Without the protection of an oil film, metal parts are prone to react with oxygen, forming an oxide film, which increases friction and makes starting difficult; 3. If the battery does not receive a charge for a long time, the sulfation process of the battery plates will accelerate, increasing the internal resistance of the battery and reducing its lifespan; 4. The battery will undergo self-discharge, lowering the terminal voltage to below 85%, which can render the battery irreparable.

Where is the USB port located in the Trumpchi GA4?

The USB port is located inside the center armrest, where you can insert and use it. Inserting a USB drive to play music is just selecting the audio source. If you were listening to music from the USB drive during your last drive, it will continue to play from the USB drive when you start the car again, and the song name will be displayed in a message window on the central control screen. Here is some relevant information about the Trumpchi GA4: 1. System Configuration: The Trumpchi GA4 is equipped with the Bosch 9.1 version ESP (Electronic Stability Program) vehicle electronic stability control system, HHC (Hill Hold Control) hill start assist system, EPB (Electric Parking Brake) electronic parking brake, and Auto Hold automatic parking function, among other intelligent safety driving assistance systems. These systems help maintain stable control of the vehicle during driving, significantly reducing the likelihood of wheel slippage on slippery roads. They provide timely feedback and take measures to address obstacles ahead, proactively eliminating potential safety hazards and ensuring vehicle safety at all times. The 360° panoramic parking imaging system, unique in its class, provides comprehensive monitoring of driving conditions, displaying a bird's-eye view of the 360° environment on the central control screen. This solves the problem of poor visibility in rainy weather, allowing for clear vision and safe driving even in the rain. 2. Safety Configuration: The Trumpchi GA4 also features comprehensive and robust passive safety configurations: it adopts the GAC high-strength body design and is built to meet the C-NCAP 5-star collision standard. The proportion of high-strength steel above 600MPa reaches 55%, with the passenger compartment strength reaching 1500MPa, far surpassing domestic models in the same class. It is also equipped with six airbags, rare in its class, along with front and rear pre-tensioned force-limiting seat belts, doubling driving safety.

What engine does the GAC Trumpchi GS4 use?

The engine of the GAC Trumpchi GS4 is independently developed and produced by GAC Motor Co., Ltd., and is a domestically manufactured engine. The engine model of the GAC Trumpchi GS4 is A415J1, with a maximum power of 124 kW, maximum torque of 265 Nm, and maximum horsepower of 169. For daily maintenance of the GAC Trumpchi GS4 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 devices in the intake and exhaust systems and usage conditions; for diesel engines, choose CB--CD grade diesel engine oil according to the mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance deteriorates, leading to various engine problems. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is clogged and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution. 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 powder from component wear to form sludge. In small amounts, it remains suspended in the oil; in large amounts, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

Subject One exam precautions: Candidates should dress appropriately, no slippers are allowed, electronic devices and bags are not permitted in the exam room. Bring your ID card and queue to enter the waiting hall. Observe the precautions and procedures on the large screen and store personal belongings in lockers before entering the exam room. Upon entering the exam room, the identity verification station will assign a seat. After finding your seat, begin the exam. Ensure the camera is aligned with you and adhere to exam discipline. If you fail the first attempt, a retake is available on the same day. If you fail again, you must pay to reschedule. After the exam, queue to collect your score report and sign it. Unsigned reports are considered invalid. There is no limit to the number of times you can reschedule Subject One. Each subject can be taken once, and if you fail, you can retake it once. If you do not attend the retake or fail it again, the exam process ends, and you must reschedule. Subjects Two and Three, however, allow only five exam attempts. Subjects Two and Three can be rescheduled after ten days. If you fail the Subject Three safe and civilized driving knowledge test, the previously passed road driving skills test results remain valid. The driver's license exam consists of three subjects: Subject One, Subject Two, and Subject Three. Subject One refers to the road traffic safety laws, regulations, and related knowledge exam; Subject Two refers to the field driving skills exam; Subject Three is divided into two parts: road driving skills and safe and civilized driving knowledge exam. The safe and civilized driving knowledge test is conducted after Subject Three, so it is commonly referred to as Subject Four. However, the official term (as per the Ministry of Public Security Order No. 123) does not include "Subject Four."
