What to Do When the Brake Light Malfunctions?

When the vehicle displays a brake light malfunction warning, it needs to be replaced promptly. Here are the detailed instructions: 1. Generally, vehicles are equipped with at least two brake lights, one on each side. Some vehicles also have an additional high-mounted brake light on the rear windshield. 2. Their function is to illuminate when the driver presses the brake pedal, alerting drivers behind to maintain a safe distance. 3. If the brake light malfunction is not addressed promptly, it will fail to alert drivers behind to keep a safe distance, significantly increasing the risk of rear-end collisions. 4. Brake lights are wear-prone components, as frequent braking in stop-and-go traffic or minor collisions can easily damage them. 5. Additionally, the vehicle's turn signals, reverse lights, and other lighting systems are also crucial. They not only serve for illumination but also provide warning and alert functions. Therefore, when the brake light or any other lighting system malfunctions, immediate repairs are necessary.

Why does engine oil leak from the exhaust pipe?

Engine oil leaks from the exhaust pipe due to the following reasons: 1. The crankcase ventilation valve is damaged, losing its sealing function and causing oil leakage. 2. Excessive exhaust gas. The piston rings lose their sealing function, allowing high-pressure gas from the cylinders to leak into the crankcase ventilation system, increasing pressure and forcing oil out through the exhaust pipe. 3. Overfilling of engine oil, which restricts air circulation in the crankcase ventilation system, forcing oil to be expelled through the exhaust pipe. Additional information about engine oil: 1. Engine oil serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption in the engine. 2. Engine oil consists of base oil and additives.

What is the correct way to buckle a seat belt?

Seat belts are designed for single-person use only, and sharing between two people is strictly prohibited. Whether you're the driver or a passenger, whether sitting in the front or back seat, the first thing to do after getting in the car is to fasten your seat belt. Here are some important points about seat belt usage: 1. Regularly inspect the technical condition of the seat belt, and replace it immediately if damaged. 2. Correctly wear the three-point lap belt. The lap belt should be positioned as low as possible, across the hips, not the waist; the shoulder belt should not be placed under the arm but should cross the chest diagonally. Seat belts are for single-person use only, and sharing between two people is strictly prohibited. Do not twist the seat belt when using it. 3. When using the seat belt, avoid letting it press against hard or fragile objects such as mobile phones, glasses, or pens in pockets. 4. Do not recline the seat back too far, as this may prevent the seat belt from retracting properly and affect its effectiveness.

Can Winter Engine Oil Be Used in Summer?

It is not recommended to use winter engine oil in summer. Here are the detailed explanations: 1. If winter engine oil is used in summer, due to its low viscosity, the formed oil film will be thinner and less stable. This will increase the friction and wear between engine components, potentially damaging the engine and shortening its lifespan. 2. Additionally, the weaker sealing performance may allow engine oil to seep into the combustion chamber, leading to oil burning and increasing maintenance costs. 3. Conversely, using summer engine oil in winter is also not advisable, as it may cause difficulties in starting the vehicle. As temperatures drop in winter, the viscosity of the oil increases, making it harder to flow and increasing engine resistance, which makes starting difficult. 4. When using single-grade viscosity oils like winter or summer engine oil, extra care is needed. Timely oil changes are essential to avoid potential damage to the engine. 5. Nowadays, more people opt for multi-grade (all-season) engine oil, which can be used year-round, offering greater convenience. If using full synthetic oil, it typically requires changing only once a year.

What Causes a 3-Cylinder Misfire in an Engine?

There are many reasons that can cause engine misfires, which can be mainly divided into the following two aspects. Below are the explanations of the causes: 1. Caused by the damage of external components, mainly including the components around the combustion chamber such as valves, valve seat rings, valve guides, spark plugs, etc. Typically, you should check the spark plugs, clean the carbon deposits on the intake and exhaust valves, and inspect whether the turbocharger has any issues, such as wear or ablation of the turbocharger impeller. 2. Misfires caused by the failure to ignite or delayed ignition of the air-fuel mixture in the cylinder. This is usually due to an abnormality in a certain component or part, causing the ECU to regulate the engine unstably, failing to meet the theoretical values calibrated by the ECU, resulting in misfires.

What brand is STRATA tires?

STRATA tires are a tire series under the Rui Lu brand. The brand has successively launched six tire models: RU06 ultra-high performance, RH07 focused on comfort, RA09 taxi wear-resistant type, RV08 urban SUV sports type, RL02 light truck type, and RW05 premium snow tires. Tires can be divided into bias-ply tires and radial tires based on their structure. Their main function is to transmit traction and braking torque, as well as to support vehicle loads, mitigate and absorb vibrations and impact forces during driving, preventing rapid damage to the vehicle caused by severe vibrations.
