The maintenance light is a reminder for the owner to perform maintenance. The wrench icon displayed on the car's dashboard is set by the manufacturer to remind the owner to perform maintenance based on mileage. When this light stays on for a long time, it is time to go to the 4S shop for maintenance. Different car models from different companies have different maintenance intervals, so please refer to the car's user manual. Car maintenance cycle: Car maintenance should be performed between 5,000 and 10,000 kilometers. The car maintenance cycle is not determined by the length of usage time but by the mileage driven. Based on the wear and tear from long-distance driving, it is determined whether maintenance is needed. Maintenance can be performed after 5,000 kilometers, and not performing maintenance beyond 10,000 kilometers will be detrimental to the car. Purpose of car maintenance: The purpose of car maintenance is to keep the car clean and in good technical condition, eliminate potential hazards, prevent faults, slow down the deterioration process, and extend the service life. Car maintenance refers to the preventive work of regularly checking, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. Car maintenance items: Replace engine oil and oil filter, replace oil filter element, air filter element, gasoline filter element, air conditioning filter element, transmission oil filter element, add windshield washer fluid, antifreeze, air conditioning refrigerant, check if the drive belt is worn, clean the throttle valve, remove carbon deposits from the cylinders, check for damage to the chassis, inspect the body and tires.

What are the penalties for out-of-town vehicles without a Beijing entry permit?

Out-of-town vehicles without a Beijing entry permit driving within the Sixth Ring Road (excluding the road itself) commit the traffic violation of "motor vehicle violating prohibition sign instructions," punishable by a 100 yuan fine and 3 penalty points. A Beijing entry permit is a temporary pass required for non-Beijing licensed vehicles to enter within the Sixth Ring Road (excluding the road itself) and certain sections outside the Sixth Ring Road in Beijing, valid for 7 days. For out-of-town passenger vehicles with a Beijing entry permit, driving within the Fifth Ring Road (including the road itself) during weekdays from 7:00 to 9:00 and 17:00 to 20:00 constitutes the violation of "motor vehicle violating prohibition sign instructions," punishable by a 100 yuan fine and 3 penalty points. Violating the tail number restriction during off-peak hours is considered "violating traffic restriction regulations," punishable by a 100 yuan fine. For out-of-town cargo vehicles with a Beijing entry permit, driving within the Sixth Ring Road (excluding the road itself) from 6:00 to 24:00 constitutes the violation of "motor vehicle violating prohibition sign instructions," punishable by a 100 yuan fine and 3 penalty points. For local cargo vehicles, yellow-label vehicles, and yellow-label vehicles from other provinces, autonomous regions, or municipalities violating the "Notice" by entering restricted areas, it constitutes the violation of "motor vehicle violating prohibition sign instructions," punishable by a 100 yuan fine and 3 penalty points.

What are the reasons for ignition shaking in GAC Trumpchi GS4?

The main reasons for ignition shaking in Trumpchi GS4 are car tire failure, severe engine carbon buildup, and unstable oil pressure. Car tire failure: During driving, if the car tire is punctured and leaks air, or if the tire pressure is too high or too low, or if the four wheels are unbalanced, these can all cause shaking in the driver's compartment while driving. Solution: The owner should get out of the car to check the tire condition. If there is no puncture, it is advisable to perform a four-wheel alignment and dynamic balance as soon as possible. Severe engine carbon buildup: The most common cause of car shaking while driving is a dirty throttle or excessive carbon buildup in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold start injector is largely absorbed by the carbon deposits, resulting in a lean mixture during cold starts, making the engine difficult to operate and causing idle shaking. Solution: Clean the engine and check the fuel system for carbon buildup, then clean if necessary. Unstable oil pressure: If the engine carbon has been cleaned, the throttle has been washed, the oil pads and spark plugs have been replaced, but the driver's compartment still shakes during driving, it is recommended to go to a 4S shop to check the fuel supply pressure and the intake pressure sensor for normal operation. If the fuel pump supply pressure is abnormal or the intake pressure sensor values are incorrect or malfunctioning, it can cause body shaking. Solution: Check the oil pressure and replace parts if necessary.

Can I Drive to Get a Tire Repair with 130 kPa Tire Pressure?

Tire pressure at 130 kPa is acceptable for driving to get a repair. When the dashboard shows tire pressure not lower than 130 kPa, you can drive slowly to the nearest service point for inflation or repair. However, if the tire pressure is below 130 kPa, driving is not recommended, and you should switch to a spare tire. Hazards of Low Tire Pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Heavier steering wheel and increased risk of veering, compromising driving safety; Excessive movement of tire components, causing abnormal heat due to over-compression; Reduced functionality of cords and rubber, leading to delamination or cord breakage, excessive friction with the rim, and damage to the bead area, resulting in abnormal wear; Multiplied friction between the tire and the ground, rapid temperature rise, softening of the tire, and a sharp drop in strength. High-speed driving may cause a blowout; Increased tire body deformation, prone to sidewall cracks, and flexing motion, leading to excessive heat, accelerated rubber aging, cord fatigue, and breakage, as well as increased tire contact area, accelerating shoulder wear. Solutions for Insufficient Tire Pressure: If no visible damage is found, simply inflate to normal pressure and reset the tire pressure system; If a puncture is detected during inspection, drive promptly to a tire shop for repair and reinflation; If the low-pressure warning reappears after inflation without a puncture, it may be due to air leakage from a deformed rim. It is recommended to inspect and replace the rim.

What noise does a broken bearing make?

A humming sound. Below are specific explanations about damage to the rear wheel bearing of a car: 1. Method to determine if it's damaged: After accelerating the car, let it coast in neutral. If the humming sound remains unchanged, it indicates a damaged rear wheel bearing. 2. Causes of rear wheel bearing damage: Broken or rusted components, entry of foreign objects, or tilting of the roller can cause damage. Prolonged exposure to acidic liquids and moisture can also lead to rusting of components; poor lubrication, if there's insufficient grease between the roller and raceway, dry friction may occur, producing abnormal metallic friction noises; clearance issues, there should be appropriate gaps between car parts, and when the distance between the roller and raceway decreases, it can easily cause friction heat, leading to bearing sintering.

What Are the Effects of a Damaged Oxygen Sensor on a Car?

Excessive emissions, deterioration of engine performance, stalling at idle, inaccurate engine operation, and reduced power are all symptoms of a faulty oxygen sensor. The role of the oxygen sensor is to control vehicle exhaust emissions, reduce environmental pollution caused by the vehicle, and improve the fuel combustion quality of the car's engine. The method for inspecting an oxygen sensor is: By observing the amplitude and frequency of the oxygen sensor's voltage changes, one can determine whether the oxygen sensor is functioning properly. To check if the oxygen sensor is working correctly, a diagnostic scanner can be used. After starting the engine and allowing it to reach normal operating temperature, the oxygen sensor's voltage should fluctuate rapidly within a range of 0.1V to 0.9V, indicating that the oxygen sensor is functioning properly. This voltage is the feedback voltage of the oxygen sensor. Common faults of the oxygen sensor include: oxygen sensor poisoning, carbon buildup, ceramic cracking in the oxygen sensor, heater resistor wire burnout, and internal wiring disconnection. Cars have both a front and a rear oxygen sensor: The front oxygen sensor's role is feedback, detecting the oxygen content in the exhaust gases produced after the combustion of the air-fuel mixture in the cylinders. A high oxygen content indicates a lean mixture, while a low oxygen content indicates a rich mixture. The rear oxygen sensor's role is to check the purification effectiveness of the catalytic converter, detecting the oxygen content in the exhaust gases after purification. Every car is equipped with an oxygen sensor, and typically, a car has two oxygen sensors—one located behind the exhaust manifold and another behind the catalytic converter. The oxygen sensor can detect the oxygen content in the exhaust, allowing the ECU to adjust the air-fuel ratio and also determine whether the catalytic converter is functioning properly.
