Does Underbody Impact Affect New Energy Vehicles Significantly?

When a vehicle experiences underbody impact, a collision force is generated between the vehicle's chassis and the object it hits. Therefore, underbody impact will more or less cause certain damage to the impacted area of the vehicle's chassis. New Energy Vehicles: New energy vehicles are powered by electricity and carry large power batteries. Structurally, the interior of a power battery can be divided into positive electrode material, negative electrode material, electrolyte, and battery separator. Among these materials, except for the positive electrode material, the other three materials are combustible, and the electrolyte has a very low ignition point. The battery separator primarily functions to isolate the positive and negative electrodes of the battery, preventing short circuits. Precautions: Underbody impact commonly occurs when driving over potholes or speed bumps at high speeds, mounting curbs, or driving on rough roads. Therefore, when driving over potholes, speed bumps, or on roads with poor conditions, it is essential to reduce speed to avoid underbody impact, which could damage the battery or even cause a fire. If underbody impact has occurred, immediately contact a service center for assistance.

Why won't a manual transmission car move after starting and engaging the gear?

Manual transmission cars may not move after starting and engaging the gear due to issues such as problems with the brake caliper, rust bonding the brake pads and brake discs together, not wearing the seatbelt, or not releasing the handbrake. The specific reasons are as follows: Brake caliper issue: The piston ring of the brake caliper may be stuck, requiring replacement of the brake caliper. Alternatively, the metal plate fixing the brake pads in the brake caliper may be deformed, necessitating replacement of the brake pad's metal plate. Brake pads and brake discs rusted together: If the car owner lives in a relatively humid area, especially after rainy or overcast days with high humidity, the brake pads and brake discs may rust and stick together after parking for a while. This situation frequently occurs in winter after washing the car. The brake discs freezing is a normal phenomenon. Not wearing the seatbelt: Some car models will automatically shift back to P gear or activate the automatic parking function if the seatbelt is not fastened or the driver's door is not properly closed. In such cases, the car cannot be driven.

What lights should be used when following a car at close range at night?

When following a car at close range at night, you should turn on the low beam. Regulations for using lights when driving at night: When meeting a vehicle from the opposite direction on a road without central isolation facilities or a center line, you cannot use the high beam within 150 meters of the oncoming vehicle; when meeting a non-motorized vehicle on a narrow bridge or narrow road without central isolation facilities or a center line, you cannot use the high beam; when driving at night in conditions with no streetlights, poor lighting, or low visibility due to fog, rain, snow, or dust, you cannot use the high beam when following a car closely in the same direction; when passing sharp curves, slopes, arched bridges, crosswalks, or intersections without traffic signals, you should alternately use the high and low beams as a signal. Violators will be fined and penalized with demerit points. The following situations require the use of low beams: Driving in areas without streetlights after dark or during dusk when it is relatively dark or at dawn when light is just appearing requires the use of low beams; in heavy fog, snow, or rain when visibility is obstructed, low beams must be used even during the day; on some roads where lighting is available but insufficient, low beams should also be used.

Is It Normal for New Cars to Have Different Tire Brands on the Front and Rear?

Under normal circumstances, all four tires of a new car should be of the same brand unless there was an assembly error at the factory or the tires were replaced later. In such cases, it is recommended to contact the 4S store or manufacturer to confirm the specific reason. Potential impacts of having different tire brands: Different tread patterns can result in varying contact areas with the ground, leading to uneven wear and potential alignment issues over time. Tires from different manufacturers may have significant structural differences, and mixing them can increase the risk of accidents. Different tread patterns and brands can also severely affect braking performance, wear patterns, and high-speed performance. Necessity of rotating front and rear tires: Rotating the front and rear tires helps prevent uneven wear, also known as tire cupping. Causes of uneven wear include suspension design, parameters during wheel alignment, and driving style. Regular tire rotation can extend tire lifespan, and it is recommended to rotate them every 20,000 kilometers. Car tires are one of the most critical components of a vehicle.

Are 300-12 and 16X30 the Same?

300-12 and 16X30 are different and not interchangeable. Below is an introduction to tire models and their functions: Meaning of tire model numbers: Most car tire models are marked in a format like 215/70R15. The numbers represent the following: 215 indicates the tire section width in millimeters, typically ranging from 145 to 285mm in increments of 10mm; 70 is the aspect ratio, representing the percentage ratio of the tire sidewall height to the tire section width, with 70 meaning 70%. Functions of tires: To transmit traction and braking torque, ensuring good adhesion between the wheels and the road surface, thereby improving the vehicle's power, braking, and passability; to work with the vehicle suspension to cushion impacts during driving and dampen resulting vibrations. They prevent severe vibrations and premature damage to vehicle components, adapt to high-speed performance while reducing driving noise, and ensure safety, handling stability, comfort, and fuel efficiency.

Do you need to watch the traffic light when turning left?

You need to watch the traffic light when turning left. If the traffic light at the intersection you need to pass through is a circular light and there is no left-turn light, you must wait for the straight green light to turn on before you can turn left. If the traffic light on the road is an arrow light marked for a left turn, you need to wait for the left-turn traffic light to display green before you can turn left. The regulations for running a red light and precautions for crossing the stop line are as follows: Regulations for running a red light: According to the new regulations for running a red light, a vehicle must pass the stop line, then pass through the entire intersection to be considered as running a red light. Precautions for crossing the stop line: If you have already crossed the stop line, stop immediately and do not move further. Reversing can easily cause a collision with the vehicle behind or pedestrians crossing the road.
