How many liters of transmission fluid are needed for an Envision 28T transmission fluid change?

If it is a manual fluid change (gravity drain), four to six liters are required; if a fluid exchange machine is used, approximately nine to twelve liters are needed. The methods for changing transmission fluid are as follows: Loosen the drain plug at the bottom of the transmission to drain the fluid, then refill. Remove the transmission oil pan directly to drain and refill the fluid: This method is more thorough than the previous one, as it removes impurities from the bottom of the oil pan. Use a transmission fluid exchange machine for automatic transmission fluid changes: A smart exchange machine can perform dynamic fluid changes, filtering and cleaning sludge and impurities inside the automatic transmission. Hazards of not changing transmission fluid for a long time: 1. Damage to the transmission's shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Affects the normal operation of the transmission, leading to damage to the transmission valve body.

What does the 'lim' mean on a BMW?

The 'lim' button on a BMW is the speed limit button. It is used for the speed limit function. After setting the speed value, the speed will be limited to a certain value, and even if you press the accelerator, the speed will not increase. This can be used to prevent speeding. The usage method is: 1. Press the 'lim' button once to turn on the 'lim' function. 2. Press it again to turn off the 'lim' function. Additional information: If the vehicle speed exceeds the set speed limit, the system will issue a warning. When reaching or exceeding the set speed limit under conditions such as downhill driving, the active braking mode will not be activated. If a speed limit lower than the current speed is set during driving, the vehicle will coast until the speed is below the limit. Since the system allows exceeding the speed limit under certain special circumstances, the driver can exceed the speed limit as needed, and in this case, the system will not issue an audible warning.

Is It Necessary to Apply Film to a Car Sunroof?

Generally, it is not recommended to apply film to a car sunroof for the following reasons: 1. Sunroof glass usually already has UV protection and heat insulation functions. Applying film again would not only result in a certain degree of resource waste but could also affect the overall quality of the vehicle. For example, after applying film to the sunroof, the increased thickness of the glass might, if not installed properly, lead to difficulties in opening and closing the sunroof smoothly. 2. Large panoramic sunroofs have a greater heat absorption area, allowing two to three times more sunlight into the car compared to smaller sunroofs, which might necessitate applying film to control the interior temperature. However, not all panoramic sunroofs are suitable for film application. If the car's sunroof glass is already tinted, it is advisable to avoid colored films to maintain the vehicle's overall aesthetic appeal. 3. Additionally, whether to apply film to the vehicle's windows or sunroof should not only be based on the owner's preference but also involve consulting professionals for advice.

Why Won't the Car Start After Being Parked for a Long Time?

The reasons why a car won't start after being parked for a long time are as follows: 1. The battery is dead due to prolonged inactivity, preventing the car from starting. The car battery is a crucial component that powers all electronic devices in the vehicle and is responsible for starting the engine. When the engine is off, the battery supplies power to the car's electronic devices. Once the engine is running, the alternator takes over powering the electronic devices. 2. The battery is a wear-and-tear part, with a typical lifespan of 3 to 4 years. However, many car batteries fail before reaching this lifespan due to improper usage habits. Avoid listening to music for extended periods, turning on headlights, or using the air conditioning when the engine is off, as these actions can shorten the battery's life. 3. When the car is not in use for an extended period, you can disconnect the negative terminal of the battery to prevent it from discharging. If the battery remains in a discharged state for too long, its lifespan will be reduced.

How to Recycle and Dispose of New Energy Vehicle Batteries?

New energy vehicle batteries are typically handled through two methods after being scrapped: step utilization and dismantling for recycling. Here are the detailed explanations: 1. Step Utilization: Currently, common new energy vehicle batteries still retain over 60% of their energy storage capacity when scrapped. Direct dismantling for recycling would be wasteful. These power batteries can be repurposed for enterprises that do not require high battery performance, such as energy storage batteries for power stations, residential buildings, or emergency power supplies. This step-by-step reuse allows for the full lifecycle utilization of power batteries. 2. Dismantling and Recycling: After step utilization, power batteries need to be dismantled and recycled. Compared to the highly polluting lead-acid batteries of the past, the mainstream lithium iron phosphate batteries today are much more environmentally friendly. They do not contain highly toxic heavy metal elements like mercury, cadmium, or lead, and elements such as phosphorus, acid, iron, and lithium can all be recycled. However, the electrolyte in ternary lithium batteries is polluting and requires multiple rounds of harmless treatment before it can be discharged into rivers.

Why does Wuling Hongguang make abnormal noises at speeds between 60 and 80 km/h?

Wuling Hongguang making abnormal noises at speeds between 60 and 80 km/h may be due to transmission issues. The possible causes are as follows: 1. Excessive wear from prolonged use leading to abnormal noises, it is recommended to visit a 4S shop for inspection and repair. 2. Abnormal noises caused by insufficient or low oil levels, it is advised to add transmission oil. 3. Abnormal noises resulting from the use of fuel or engine oil that does not meet the original vehicle specifications, it is recommended to replace with original oil. 4. Abnormal noises due to improper use and maintenance, it is suggested to use the vehicle properly and adhere to maintenance schedules to ensure extended transmission life. 5. Abnormal noises caused by increased gaps, component damage, loose or stuck bearings due to wear, poor lubrication, or substandard parts quality. Inspect worn parts and replace if necessary. 6. For other potential causes, it is advisable to promptly visit a repair shop for inspection and repair.
