If the coolant light is on, it indicates a lack of coolant or a malfunction in the cooling system. If there are no signs of engine overheating, you may continue driving for a short distance, but for safety reasons, it is best to stop and inspect the issue before continuing. Below are the reasons why the coolant light may illuminate: 1. Insufficient coolant. The engine coolant is consumed to ensure normal operating temperatures for all internal engine components. When the coolant level falls below the Min (minimum) mark, it indicates a shortage of coolant, triggering the warning light. In this case, simply refilling the coolant will turn off the warning light. 2. Overheating. After prolonged high-speed operation, the engine may experience slow heat dissipation, leading to overheating. This can also cause the coolant light to illuminate. The solution is to stop the vehicle and let it cool down naturally. 3. System malfunction. Vehicles are equipped with numerous sensors, and a system failure may cause some sensors to malfunction, resulting in the coolant light turning on. In this situation, further inspection at a repair shop or 4S store is required. 4. Engine failure. Engine malfunctions can also trigger the coolant light. In such cases, stop the vehicle immediately and wait for assistance.

Does Turning the Steering Wheel While the Car is Stationary Damage the Vehicle?

Turning the steering wheel while the car is stationary can damage the vehicle. Rotating the steering wheel when the car is not moving not only places a significant load on the steering system but also causes considerable wear and tear on the tires, making it a behavior that is considered harmful to the car. Below is an introduction to relevant content about steering wheel usage: Precautions for Turning the Steering Wheel: When turning the steering wheel, it's advisable to turn more and return more, or turn less and return less; the speed of returning the steering wheel should be quick and accurately back to position. Avoid applying excessive force when the steering wheel is about to reach its limit, as this can easily damage mechanical components. When driving in hazardous mountainous areas or on poor road surfaces, always grip the steering wheel with both hands to prevent accidents. Try to avoid turning the steering wheel while the vehicle is stationary. Reasons to Avoid Turning the Steering Wheel While Stationary: Turning the steering wheel while the car is stationary means that part of the tire tread is in direct friction with the ground. Due to the camber angle set for the front wheels, the inner side of the tire tilts inward when the steering wheel is turned (the outer side forms a negative camber angle, and the inner side forms a positive camber angle). In such conditions, the tires alone bear the weight of the vehicle, which can also cause significant damage to the tires.

What does the fault code 84 for Buick Excelle mean?

Engine power reduction, it is recommended to check the spark plugs. Here are the relevant introductions: 1. Carbon deposit issue: Carbon deposits here include cylinder carbon deposits, throttle carbon deposits, spark plug carbon deposits, intake carbon deposits, etc. These areas are closely related to the engine's power output. When there is excessive carbon deposit inside the engine, the car's ignition energy decreases, intake efficiency drops, ultimately leading to reduced engine power and idle weakness. 2. Engine maintenance precautions: The air filter needs to be replaced regularly. If the engine's output power still seems lower than before after replacing the air filter, then it is necessary to check whether the intake pipe is too dirty. Dust and particles entering the engine can wear down engine components.

Does the ETC need to be reactivated if it was removed during window tinting?

ETC needs to be reactivated if it was removed during window tinting. Methods to reactivate ETC: Insert and remove the ETC card twice consecutively until the electronic tag screen displays "Bluetooth is on". If "Tag invalid" appears when inserting and removing twice without the electronic tag attached, this is normal and does not affect activation. Alternatively, you can directly press the button on top of the electronic tag to enable Bluetooth. Turn on your phone's Bluetooth, open the corresponding mobile app (usually there is a download QR code on the electronic tag), and enter the device activation interface. Click "Device Connection" and wait patiently for the "Connection successful" prompt. Once connected successfully, upload a photo of the vehicle's front to complete activation. ETC installation positions: For small vehicles like cars and minivans, the ETC card and OBU device should be installed on the upper middle part of the front windshield. For large vehicles like trucks and buses, the installation position is on the lower middle part.

What to Do If Your Car Is Struck by Lightning While Driving?

If your car is struck by lightning while driving, there is no need to panic. Cars are equipped with lightning protection features. After being struck, you should promptly find a safe place to pull over, avoid hastily exiting the vehicle, and inspect the car's condition once the rain stops. Below is an introduction to the relevant details: 1. Faraday Cage: The metal shell of the car provides excellent protection for its interior, completely shielding it from external electric field changes. This means the car is not afraid of lightning strikes, and the occupants inside are very safe. 2. Lightning Strike Damage: Despite the protection, a lightning strike can still cause significant damage. When a car is struck by lightning, the instantaneous high voltage can potentially damage the electronic components inside, leading to malfunctioning electrical equipment and, in severe cases, even causing a fire.

What number should I call if my vehicle breaks down on the road?

If your vehicle breaks down and you have insurance, simply call your insurance company. If uninsured, you can call 122 for road assistance. Below are solutions for vehicle malfunctions: 1. Steering wheel vibration: Pay attention to daily tire maintenance. If aging causes vibration, consider replacing the tires. If noticeable vibration occurs at specific speeds, rebalancing the tires is recommended. 2. Brake failure or complete loss: Maintain the brake system thoroughly by regularly checking wear on components like brake discs and pads, replacing them if necessary. During daily driving, avoid prolonged brake application. For long downhill sections, use lower gears with engine braking to prevent brake pad overheating.
