Tunnels do not allow overtaking or lane changing. Tunnels are special sections of highways. Compared to regular road sections, tunnels have poor lighting and limited space. If drivers do not comply with traffic regulations and change lanes or overtake at will, it can easily interfere with other vehicles and cause accidents, leading to traffic congestion, delays, or even secondary accidents. Precautions for driving in tunnels: 1. Do not use high beams: Most tunnels nowadays are equipped with lighting, which, although not very bright, is sufficient with low beams. High beams should never be used because tunnels are inherently narrow, making oncoming traffic stressful. High beams can instantly blind drivers of oncoming vehicles in this confined space. If an accident occurs in one vehicle, it could potentially disrupt the entire tunnel traffic. 2. Pay attention to light changes: When entering a tunnel, the surrounding space becomes darker, causing the pupils to contract to adapt to the dark environment. After driving in a tunnel for an extended period and approaching the exit, the bright light at the exit may appear as a blinding white light, temporarily impairing vision. During this brief adaptation period, remain calm and continue driving normally. As long as you stay composed, accidents can generally be avoided.

When the parking indicator light on the car is illuminated, it means the parking brake is engaged, and the color of the parking brake indicator is red. 2. Simply put, the parking brake is the handbrake of the car. The function of the handbrake is to provide resistance to the car when parking, applying the brake to prevent the car from rolling. Additional information: When performing parking brake operation, you need to press down on the brake pedal, then pull up the handbrake on the car, and finally release the brake pedal to secure the car in place.

What does engine SCR mean?

SCR stands for "Selective Catalytic Reduction" technology, which is a method for diesel engine exhaust treatment. The technical approach involves first addressing the particulate emissions of diesel engines through internal purification techniques such as optimizing in-cylinder combustion and reducing oil consumption. Subsequently, an SCR aftertreatment device is employed to reduce NOx emissions from the engine. Relevant information about the catalyst is as follows: 1. Currently, the catalysts used internationally mainly include V2O5/WO3(MoO3)/TiO2 and other vanadium-containing and metal-based zeolite catalysts. 2. Zeolite catalysts exhibit excellent low-temperature characteristics and high conversion efficiency at high space velocities. Vanadium-based catalysts have become commonly used due to their internationally recognized high conversion activity and certain resistance to SO2 poisoning.

How to Handle a Tire Blowout While Driving?

A sudden tire blowout while driving is a terrifying experience. If not handled correctly, it can easily lead to more severe consequences. So, how should one deal with a sudden tire blowout while driving to ensure maximum personal safety? After discovering a tire blowout, never slam on the brakes. It's important to focus on prevention in daily life to eliminate the hidden dangers of tire blowouts. Driving with underinflated tires is one of the main causes of blowouts. Driving with underinflated tires leads to a significant increase in friction between the tire and the road as the tire pressure drops, causing the tire temperature to rise, the tire to soften, and its strength to decrease. In such conditions, high-speed driving can result in a blowout. Even at low speeds, it can damage the tire, creating a potential blowout hazard for future high-speed driving. Of course, having excessively high tire pressure is also unsafe. It's crucial to pay attention to tire protection in daily life, regularly check tire pressure, and maintain standard tire pressure. If a tire is punctured by a nail or is slowly losing air, it is recommended to repair it promptly.

What are the reasons for the car headlight low beam not working?

There are mainly the following situations when the car headlight low beam is not working, which are: 1. The low beam bulb may be faulty. 2. The low beam control switch may be faulty. 3. There may be a fault in some circuits. Extended content: Troubleshooting methods for car headlights not working: 1. Check if the fuse is blown: Use a screwdriver to connect the dimmer switch live wire to the high and low beam terminals respectively, and observe the following situations: (1) If all lights are on, it indicates a fault with the dimmer switch. (2) If the high beam is on but the low beam is off when connected, the fault lies between the dimmer switch and the headlight or between the dimmer switch and the low beam. (3) If the high beam is not working, check if the high beam indicator is on. If it is, the fault is between the terminal block and the headlight; if not, the fault is between the terminal block and the dimmer switch. (4) If only one headlight is working and the other is not, it may be due to a burnt filament, an open circuit, or poor grounding. 2. The car light bulb is burnt out (1) The voltage regulator is faulty, causing excessive voltage. (2) Poor contact of the battery terminals, resulting in excessive no-load voltage from the generator. (3) There is a short circuit between the generator armature and the field coil.

What are the parking steps for the all-new Magotan B8?

The detailed parking steps for the all-new Magotan B8 are as follows: 1. Press the brake and shift the gear to N (Neutral) position. This will secure the vehicle's position. Then press the brake again and shift to the parking gear (P), which will release the stress between the hook and the gear. 2. Pull up the handbrake, release the brake, and finally shift to P (Park) position. This avoids putting stress on the parking lock mechanism and prevents damage. Additional information: The all-new Magotan B8 has a length, width, and height of 4866/1832/1464 mm respectively. The wheelbase is 2871 mm, which is 80 mm longer than the overseas model and 59 mm longer than the current model, providing a very spacious interior.
