Is Steering Wheel Shaking Due to Wheel Balancing or Four-Wheel Alignment?

What are all the lights on a car?

All vehicle lights include headlights, position lights, fog lights, license plate lights, reverse lights, turn signals, brake lights, clearance lights, and dome lights. In sedans, the headlights, front turn signals, and front position lights are assembled together, called the front combination lamp, while the rear turn signals, brake lights, rear position lights, rear fog lights, and reverse lights are assembled together, called the rear combination lamp. Related introduction: 1. Function of the front combination lamp: In situations with insufficient light (such as at night, in tunnels, underground garages, or rainy weather), to ensure driving safety, the sensor located above the dashboard on the inner side of the front windshield will automatically turn on the headlights, which will turn off when there is sufficient light. 2. Function of the rear combination lamp: To alert the behavior of the vehicle and remind the following vehicles to pay attention and avoid.

How to Use Reserve Fuel When the Car Runs Out of Gas?

Only vehicles equipped with primary and secondary fuel tanks can utilize a reserve fuel tank. Regular cars do not have a reserve fuel tank; in such cases, you can contact your insurance company for fuel delivery. Relevant information: 1. Fuel tank function: In addition to storing fuel, the fuel tank in a hydraulic system also serves to dissipate heat, separate air bubbles from the oil, and settle impurities. The fuel tank is equipped with many auxiliary components, such as coolers, heaters, air filters, and liquid level gauges. 2. Precautions: Try not to wait until the fuel gauge lights up with a yellow warning indicating low fuel before refueling. This is because the oil pump may not operate smoothly, potentially damaging the oil pump and also inconveniencing your travel plans.

Is the Vehicle Annual Inspection Calculated by Exact Date?

Vehicle annual inspections are calculated by exact date and cannot be overdue. Relevant information: 1. Regulations: According to the "Road Traffic Safety Law," passenger vehicles for commercial use must undergo annual inspections within the first 5 years; after 5 years, inspections are required every 6 months. Trucks and large/medium-sized non-commercial passenger vehicles must undergo annual inspections within the first 10 years; after 10 years, inspections are required every 6 months. 2. Other rules: Small and micro non-commercial passenger vehicles must undergo inspections every 2 years within the first 6 years; after 6 years, annual inspections are required; after 15 years, inspections are required every 6 months. After 20 years, vehicles must undergo 4 regular inspections annually starting from the 21st year. Therefore, vehicle inspections can only be conducted in advance, not delayed.

What position should the seat safety headrest be adjusted to?

The correct position for the safety headrest is as follows: 1. Headrest height: When your head rests on the headrest, the middle of the headrest should align with the middle of your head. 2. Method to adjust the headrest position: Adjust the headrest height to the top of the passenger's eyes or ears, keeping the distance between the back of the head and the headrest as close as possible, preferably no more than 10 cm, to maximize the safety of the driver's neck. 3. Function of the headrest: The headrest provides a comfortable feeling for the driver and passengers while protecting their neck and head from injury.

What is the Standard Height for Car Low Beam Headlights?

There is no standard regulation specifying the exact height in meters for car low beam headlights, only requirements for the luminous intensity and beam position of headlights. Generally, on level roads, car low beams should illuminate the area 25-35 meters ahead of the vehicle. Below are the regulations regarding car lighting: 1. On roads without central barriers or center lines, drivers should switch to low beams when meeting oncoming vehicles at a distance of 150 meters or more. Low beams should also be used when meeting non-motorized vehicles on narrow roads or bridges. 2. When driving at night on roads without streetlights, under poor lighting conditions, or in low visibility situations such as fog, rain, snow, dust, or hail, vehicles traveling in the same direction should use low beams when following closely behind another vehicle. 3. When passing through sharp curves, slopes, arched bridges, pedestrian crossings, or intersections without traffic signals at night, drivers should alternately switch between high and low beams as a signal. 4. When driving at night on unlit roads at speeds below 30 km/h, low beams may be used; when speeds exceed 30 km/h, high beams may be used. On well-lit roads at night, low beams should be used.

Can You Still Drive When the Engine Warning Light Is On?

The engine warning light comes in two colors: yellow and red. When the yellow warning light is on, you can continue driving. However, when the red warning light is on, you must stop driving immediately. When the yellow warning light is on, it serves as a caution, indicating that certain system parameters in the car may have exceeded the set range. The vehicle can still be driven, but some functions may be restricted. When the red warning light is on, it signifies a prohibition, meaning the issue is severe. The car must be stopped immediately, the engine turned off, and driving must not continue. The cause of the fault should be checked. There are seven main reasons why the engine warning light may illuminate: 1. Sensor malfunction: This includes sensors such as the coolant temperature sensor, crankshaft position sensor, mass airflow sensor, intake air temperature sensor, and oxygen sensor. If these sensors are damaged, have poor connections, or their signals are interrupted, the car's ECU cannot accurately obtain engine data, triggering the warning light. 2. Fuel or oil quality issues: Using fuel or engine oil that does not meet the manufacturer's specifications may cause engine wear and trigger the warning light. 3. Poor fuel mixture combustion: This can lead to engine carbon buildup or knocking. When detected by the oxygen sensor and reported to the ECU, the warning light will illuminate. Issues like faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can cause poor combustion. 4. Turbocharger problems: Issues with the intake boost system or turbocharger can also trigger the warning light. The most common problem is a damaged turbocharger, often accompanied by symptoms like oil leaks, excessive oil consumption, reduced power, metallic noises, or blue/black smoke from the exhaust. 5. Intake issues: Blockages in the engine's intake system can lead to the warning light turning on. A dirty or uncleaned air filter can cause intake problems. 6. Exhaust issues: Faults in the exhaust system, such as problems with the rear oxygen sensor, catalytic converter, exhaust camshaft, or bearings, can trigger the warning light. The catalytic converter is the most common culprit, often due to the use of leaded gasoline, lead- or silicon-containing oil additives, physical damage, or fuel system issues. 7. Anti-theft system malfunction: If the car's electronic anti-theft system fails or the anti-theft controller is incompatible with the engine's ECU, the engine may not function properly, and the warning light may illuminate. If the engine warning light is on, follow these steps: 1. First, check if the engine is running normally. Look for signs of shaking, smoke, etc. If these symptoms are present, avoid restarting the engine—especially if the red warning light is on. 2. If the engine can be started, turn it off and wait 5–10 minutes. Without pressing the brake, press the start button once or turn the key halfway to the 'ON' position (without pressing the clutch). The car will perform a self-check. After 5–10 seconds, check if the warning light turns off. 3. If the warning light remains on, visit a service center as soon as possible. Technicians can use a diagnostic tool to read the fault code, identify the issue, and perform targeted repairs.
