What Does the Orange Exclamation Mark on the Car Mean?

The appearance of an exclamation mark on the car dashboard indicates an abnormality or malfunction in the corresponding system. Many indicator lights on the car dashboard feature an exclamation mark, such as the tire pressure indicator light, lighting fault indicator light, steering system fault indicator light, brake system fault light, transmission fault indicator light, and windshield wiper fault indicator light. Below is a detailed introduction to the exclamation mark warning lights: General Fault: A triangle with an exclamation mark inside indicates that the car's general performance, components, or functions have malfunctioned. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, and engine oil pressure sensor failure. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a fault in the transmission or that the transmission lubricant is below the normal range. The transmission fluid should be replaced promptly. Brake System Fault: An exclamation mark inside a circle with parentheses represents a warning for the brake system, mainly indicating a brake system malfunction or low brake fluid level. The brake system should be inspected immediately to avoid accidents. Tire Pressure Anomaly: An exclamation mark below a horizontal line with parentheses represents the tire pressure monitoring warning light, which illuminates when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator light, signaling a fault in the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lights to identify the issue. In addition, during daily vehicle use, the warning lights displayed on the dashboard are divided into two colors, yellow and red, indicating different levels of severity: Yellow indicates a fault in the corresponding system that is not very serious. Reduce speed and proceed to a repair shop to eliminate potential safety hazards. Red indicates a very serious problem in the corresponding system. In such cases, do not continue driving. Pull over safely and seek professional assistance to prevent unforeseen dangers to the vehicle and personal safety. It is important to note that when the car is started, all lights will illuminate for an automatic system check and will turn off after the check is completed. If a light does not turn on when the ignition is switched on, remains lit, or lights up while driving, it indicates a fault in the related system. In such cases, seek professional help promptly to inspect and eliminate safety hazards.

What to Do When the Car Engine Temperature Warning Light Comes On?

When the engine temperature warning light comes on, you should pull over and inspect the vehicle. Park in a safe area but do not turn off the engine—keep it running at idle to allow the engine to continue operating, and open the hood to dissipate heat. Note: If you see steam rising from the hood, observe carefully and avoid opening it hastily to prevent burns. Below are the relevant details: 1. Reasons for the engine temperature warning light coming on: insufficient coolant; engine overheating; cooling fan malfunction or failure; damaged thermostat. 2. Why you shouldn't turn off the engine: For most vehicle models, the cooling system's water pump is driven by the engine. Turning off the engine stops the water pump, halting coolant circulation. Meanwhile, the engine components remain at high temperatures. Without effective cooling, this could damage the engine. 3. Specific steps: After parking, first check if the coolant level in the auxiliary tank is too low. Open the engine hood and inspect the coolant level in the auxiliary tank. If the level is below the 'min' line, it indicates the coolant is insufficient. Then, check if the cooling fan is functioning properly. A faulty cooling fan can cause the coolant temperature to rise. If the fan is stuck, you can disconnect the power and resolve the issue yourself as soon as possible. If it's a wiring problem, you'll need to call for roadside assistance.

How to Deal with the UY125 Engine Light Staying On?

The methods to handle the engine light staying on are: 1. Find a safe place to stop and check if there are any abnormal noises from the engine, and check for oil leaks. If no abnormalities are found after inspection, it may be a false alarm from the fault sensor light. 2. If the engine fault light is on, there are no abnormal noises in the engine compartment, no other abnormal prompts on the dashboard, the vehicle's power is not affected, and the transmission shifting is unaffected, you can continue driving to a 4S shop for further inspection. Here is some related information: The yellow engine fault light is also called the EFI system fault light. As long as there are no special abnormalities in the engine power and sound, the vehicle can still continue to drive.

Can You Add Engine Oil Directly If It's Low?

You can add engine oil directly if it's low. The steps to add engine oil are: 1. Open the engine hood; 2. Locate the oil filler port; 3. Add engine oil and check the oil level or for any leaks. The functions of engine oil include: lubrication, auxiliary cooling, cleaning, sealing and leak prevention, rust and corrosion prevention, shock absorption, and anti-wear. The method for changing engine oil is: 1. Lift the car, remove the undercover, and place a container of about 10 liters under the oil drain plug; 2. Unscrew the oil drain plug, use an air gun to blow into the oil filler port for two minutes, then tighten the oil drain plug after draining and wipe it with a tissue to check for leaks; 3. Reinstall the undercover and lower the car, then use a funnel to add engine oil through the filler port.

What is the Chinese meaning of cruise on a car?

The Chinese meaning of cruise on a car is the automotive electronic cruise control system, which allows the driver to set the vehicle at a fixed speed, enabling the car to travel accurately at the preset speed. Cruise control should not be used in the following road conditions: 1. In principle, cruise control is used on highways or fully enclosed roads. On non-enclosed roads, complex road conditions are not conducive to traffic safety. 2. It is prohibited in rainy weather and snowy/icy conditions. 3. It should be disabled on winding mountain roads or roads with too many curves. Under normal circumstances when exiting a curve, appropriate acceleration is needed to provide greater steering force. In cruise control mode, the vehicle automatically maintains a constant speed, with the throttle controlled by the onboard computer, which often poses dangers when driving on curved roads. Under such conditions, the speed should be appropriately controlled. 4. Cruise control is also unsuitable on roads with heavy traffic.

Does Removing the Catalytic Converter Make the Car More Powerful?

The catalytic converter does affect the exhaust efficiency of the engine. After removing the catalytic converter, due to the reduction in exhaust backpressure (improved flow), the vehicle can deliver stronger power during high-speed driving. However, the issue is that the reduction in exhaust backpressure also impacts the exhaust backpressure balance, ultimately leading to a decrease in low-end torque. Below are the relevant details: 1. Definition of the catalytic converter: The catalytic converter is one of the most critical components in the exhaust emission purification system of gasoline vehicles. 2. Function of the catalytic converter: It is responsible for the catalytic reduction of harmful gases in vehicle exhaust, such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx). It converts CO, HC, and NOx into non-toxic and harmless substances like water (H₂O), carbon dioxide (CO2), nitrogen (N2), and oxygen (O2) before they are released. 3. Hazards of removing the catalytic converter: Illegally removing the catalytic converter not only violates national laws and regulations but also becomes a major contributor to damaging the Earth's ecological environment.
