First, eliminate the most suspected battery issue. For a car that cannot start, check if the battery voltage is too low to power on or if the battery is damaged. Next, check whether the car's fuel gauge is below the warning line. If the car is out of fuel, it will also fail to start. Then, consider whether the driver's operation is the problem, leading to failure in one-button start. Improper operation occurs more frequently for new cars or novice drivers. Finally, consider whether the driver has any bad parking habits. For example, if the driver only engages the handbrake but forgets to shift the gear lever to the P position when parking.

I remember that time when my electric car's 12V auxiliary battery suddenly died, mainly because I left it parked for too long without driving, and the battery automatically discharged. When this happened, I immediately pulled over to a safe spot and turned on the hazard lights. Then, I found jumper cables and got a friend's car to help connect the positive and negative terminals for charging. After about ten minutes of charging, I tried starting the car, and it worked fine. Afterward, I even bought a portable jump starter to keep on hand—super convenient. For prevention, I recommend driving at least a short distance every week to let the system automatically charge the battery, especially in winter when cold temperatures make it easier for the battery to drain. It’s also good to regularly check the battery health—just use a multimeter to test the voltage and keep it above 12V. Don’t wait until there’s a problem to regret it.

When I first drove an electric car, I ran into a depleted battery and was stranded on the roadside, feeling helpless. Safety first, I immediately pulled over, turned on the hazard lights, and called for roadside assistance. Experience taught me to keep a smart battery monitor at home—its app shows real-time battery levels and alerts when it drops below 10%. For daily driving, try to use energy recovery features, charge frequently, and avoid frequently turning on/off electrical appliances like air conditioning or headlights. Battery maintenance is simple: regularly clean the electrodes to prevent oxidation; if corroded, treat with baking soda solution. Don’t tamper with wiring yourself to avoid short-circuit risks. Have a professional technician perform a full inspection annually to ensure system reliability.

What Does It Mean When the Illumination Distance of Vehicle Lights Changes from Near to Far at Night?

When the illumination distance of vehicle lights changes from near to far at night, it indicates that the vehicle may have entered a downhill slope, or transitioned from a curved road to a straight road. It could also mean the slope has changed from a gentle downhill to a steep downhill, or the vehicle is moving from a downhill slope onto a flat road. Precautions for Nighttime Driving: Reduce speed. Visibility at night is not as good as during the day, so drive slowly and maintain an appropriate speed. Use high and low beams correctly. Use low beams during normal driving to avoid inconveniencing oncoming vehicles. Switch to high beams when turning or going uphill to signal the presence of your vehicle to others. Maintain a safe distance from the vehicle ahead. Poor visibility and slower reaction times at night increase the risk of rear-end collisions if following too closely, so keep an appropriate distance. Use the horn when necessary. Be alert for pedestrians crossing the road at night and use the horn or flash lights to warn them in advance. Avoid unnecessary overtaking. Overtaking at night should be done cautiously, ensuring sufficient straight-line distance and avoiding curves. Before overtaking, approach the vehicle ahead and use light signals to indicate your intention to pass, waiting for them to yield before accelerating.

What is the actual measured ground clearance of the Tiggo 8?

The ground clearance of the Tiggo 8 is 200mm. The correct term for chassis height should be minimum ground clearance, which refers to the distance between the lowest point of the car's chassis and the ground when the car is at its maximum load capacity. The passability of a car is largely reflected in the data of the minimum ground clearance. In previous standards, there were regulations for the minimum ground clearance, which usually had to be between 150mm and 160mm. The chassis height (minimum ground clearance) of family cars is usually in the range of 110mm to 150mm. For family cars, if the chassis height exceeds 130mm, the car can more easily pass through various complex road surfaces, but the high-speed stability is poorer. The smaller the ground clearance (below 110mm), the better the stability of the car at high speeds, but the passability is worse. Methods to increase car ground clearance: If you need to increase the ground clearance of the car, you can add spacers at a car modification shop. For better results, you can also replace the shock absorber. Impact of car ground clearance: The larger the ground clearance, the stronger the vehicle's ability to pass over obstacles or uneven ground, but the higher the center of gravity, which reduces stability. The minimum ground clearance refers to the distance between the lowest point of the car (excluding the wheels) and the supporting plane when the car is fully loaded and stationary, used to characterize the car's ability to pass over obstacles such as stones and tree stumps without collision.

Will driving below 60 km/h on an expressway result in penalty points?

Driving below 60 km/h on an expressway will not result in penalty points, but if the speed is too slow and causes traffic congestion, traffic police may impose on-the-spot penalties. Characteristics and regulations of expressways: An expressway refers to a dual-carriageway road with a central divider, fully controlled access via interchanges, designed to serve high-volume, long-distance, and rapid urban traffic. It features smooth alignment, separation from regular roads, allowing vehicles to travel safely and smoothly at higher speeds. Key characteristics include: a central barrier completely separating opposing traffic; prohibition of mixed traffic with non-motorized vehicles, motorcycles, or pedestrians; controlled spacing of access points to maintain relative independence from other arterial roads, collector roads, and local streets; minimal at-grade intersections (provided they don't affect overall traffic flow), with mandatory grade separation at crossings with other highways, railways, or major transportation lines. Speed limits on expressways: For expressways with four or more lanes in each direction, the speed limit ranges from 60 km/h to 100 km/h (with suburban sections of highways allowing up to 120 km/h). Penalties for violating speed limits: Current domestic laws and regulations primarily impose strict rules on speeding. For example, on highways with a 120 km/h limit, exceeding the speed by more than 10% results in varying penalties. Highways also have minimum speed requirements—driving at speeds more than 20% below the posted limit will incur a 3-point penalty. For other roads, there are fewer regulations regarding low-speed limits.

How to Replace the Manual Transmission Fluid for Buick Excelle?

Different models require varying amounts of fluid and have different replacement intervals. Please refer to the user manual and maintenance manual for specific instructions. Below is the replacement procedure for the 2008 Buick Excelle: 1. Prepare the following tools in advance: two sets of jacks and safety stands, a flat-head screwdriver, a ratchet wrench, an extension bar, a 17mm and a 13mm socket, a basin, a plastic funnel, cardboard, work clothes, an empty bottle, manual transmission lubricant, and sealant. 2. Park the car securely, engage the handbrake, and remove the key. Place a brick behind each rear wheel to prevent the car from rolling backward during the operation. 3. Use a jack to lift the front of the car and place safety stands behind the jack. 4. Lay cardboard under the car and place a basin to catch the draining fluid. 5. Use a ratchet wrench, extension bar, and 13mm socket to loosen the 10 bolts on the transmission oil pan counterclockwise. 6. Remove the transmission oil pan. 7. Clean the contact surface of the transmission oil pan and apply sealant to the pan. 8. Wait 5-10 minutes for the sealant to dry slightly, then reinstall the oil pan. Tighten the bolts gradually, starting from the middle and moving to the ends. 9. Open the hood and use a flat-head screwdriver to pry off the plastic cap on the pressure relief valve. 10. Use a ratchet wrench, extension bar, and 17mm socket to loosen the manual transmission pressure relief valve counterclockwise. 11. Pour the manual transmission lubricant into an empty bottle using a plastic funnel, then pour it into the manual transmission through the funnel. 12. Check for any leaks around the oil pan, which are generally uncommon. If everything is normal, reinstall the pressure relief valve and cap, then remove the safety stands and jack.

How many kilometers can a normal car drive before being scrapped?

Non-commercial vehicles and commercial vehicles have different scrapping periods, as detailed below: Scrapping regulations for non-commercial vehicles: For household 5-seat sedans and 7-seat SUVs, there is no usage period limit for non-commercial small and mini vehicles. When the normal mileage reaches 600,000 kilometers, the state will guide the scrapping. In addition to the above vehicles, small and mini non-commercial passenger cars, large non-commercial sedans, and wheeled special machinery vehicles also have no usage period limit. Common scrapping regulations for commercial vehicles: Small and mini taxi passenger cars have a scrapping period of 8 years, medium-sized taxi passenger cars have a scrapping period of 10 years, and large taxi passenger cars have a scrapping period of 12 years. Public transport passenger cars have a scrapping period of 13 years, other small and mini commercial passenger cars have a scrapping period of 10 years, and large and medium-sized commercial passenger cars have a scrapping period of 15 years. Mini commercial trucks have a scrapping period of 8 years, light and large commercial trucks have a scrapping period of 10 years. The vehicle scrapping process is as follows: The car owner applying for scrapping and renewal must fill out one copy of the "Application Form for Vehicle Change, Transfer, Modification, Suspension, and Scrapping Approval" and stamp the owner's seal. The registration office accepts the application and issues a "Vehicle Scrapping Notice" for vehicles that have reached the scrapping period. For vehicles that have not reached the scrapping period, after inspection by the vehicle inspection office, if they meet the scrapping standards, a "Vehicle Scrapping Notice" will be issued. The owner can choose a qualified recycling company to dismantle the vehicle with the "Notice". The recycling company will dismantle the vehicle and take photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The owner must submit the "Change Form", "XX Province Vehicle Renewal Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and photos of the dismantled vehicle to the vehicle inspection office for verification and signature. The license plates will be recycled, and the application will be submitted for approval according to regulations to complete the scrapping registration. Special notes: According to Article 30 of the "Motor Vehicle Registration Regulations", if the vehicle is damaged and cannot be driven back to the registration location, the owner can sell the scrapped vehicle to a local motor vehicle recycling company. If a commercial vehicle is converted to a non-commercial vehicle, it must be scrapped according to the original commercial vehicle's scrapping period. According to Article 43 of the "Motor Vehicle Registration Regulations", after completing the transfer or cancellation of motor vehicle registration, the original owner can apply to the vehicle management office to use the original license plate number when registering a newly purchased vehicle. The application to use the original license plate number must meet the following conditions: (1) The application must be submitted within six months after the transfer or cancellation registration; (2) The owner must have owned the original vehicle for more than three years.
