What Causes Strange Noises While Driving?

Why Do I Always Feel Sleepy While Driving?

Here are the specific reasons for feeling sleepy while driving: 1. Poor air circulation in summer: Drowsiness while driving is more likely to occur in summer due to high temperatures and poor air circulation inside the car, especially in the afternoon when the human body is prone to drowsiness. Driving on monotonous highways can further enhance the hypnotic effect, increasing the driver's sleepiness. 2. Biological clock: Drivers who are accustomed to taking naps are more likely to feel sleepy at their usual nap time after lunch due to their biological clock. Additionally, after eating, the digestive system requires more blood, diverting it from other parts of the body, including the brain, leading to reduced blood flow and oxygen supply to the brain, which results in drowsiness.

Can the car recorder see inside the car?

Dual-lens dash cams can record the interior of the car, while single-lens dash cams cannot. Here are the specific steps to use a dash cam: 1. Insert the memory card: Insert the memory card while the dash cam is turned off, then restart it. 2. Install the app: Install the app on your phone by scanning the QR code provided by the seller or following the software name indicated in the manual. 3. Connect via password: Before opening the app, go to the WiFi settings interface and select the dash cam's WiFi (the WiFi name is usually specified in the manual and often appears at the top of the WiFi list). Enter the password to connect. After entering the app, you can modify the WiFi access password—proceed with caution. 4. Successful connection: Once connected, you can perform real-time functions such as recording, taking photos, playback, downloading, sharing, and system settings on your phone. This method applies to all Android and iOS devices.

What are the common causes of high car water temperature and their solutions?

Common causes of high car water temperature include coolant leakage or insufficient coolant, radiator fan failure, water pump failure, thermostat failure, and poor radiator heat dissipation. Below are the methods to address high engine water temperature: 1. Park in a shaded area: If you notice high engine water temperature while driving, find a safe and shaded place to pull over. Let the vehicle idle without turning off the engine, as shutting it down will stop the cooling fan and coolant circulation, leading to even higher engine temperatures. 2. Check the radiator fluid: Inspect the fan for any abnormalities, check for leaks in the radiator hoses, and ensure the coolant level is sufficient.

What are the protection methods for cars parked outdoors?

For vehicles parked outdoors, it is best to wax them every 2-3 months. The following are the advantages and disadvantages of car waxing: 1. Advantages: (1) Heat resistance. Car wax can effectively protect the cleanliness of the car paint surface, prevent UV rays, and extend the lifespan of the paint. (2) Anti-static. While driving, the friction between the car body paint and dust in the air generates static electricity. Car wax can effectively block the friction between airborne dust and the car paint surface, providing protection. 2. Disadvantages: (1) Prone to oxidation. Car wax uses petroleum as a solvent, which is prone to oxidation. The longer the time, the more obvious the oxidation. After the car wax and glaze are completely oxidized, they can no longer protect the paint surface. (2) Can wear the paint surface. Car wax contains abrasive particles. If the waxing technique is incorrect, it can wear the paint surface.

How to Remove a Car Headrest?

To remove the headrest, you need to loosen the seat back lining and the buckle, then release the headrest lock. Below is relevant information about car headrests: 1. Function: A car headrest is a comfort and safety accessory designed for driving. In the event of a rear-end collision, the human body tends to jerk backward due to inertia. At this moment, the pressure from vehicle acceleration or deceleration concentrates on the vulnerable neck and head areas. The headrest serves as a cushion, protecting the head. 2. Classification: Car headrests are mainly divided into two categories: non-adjustable and adjustable. Adjustable car headrests can be further categorized into manually adjustable and automatically adjustable types. Manually adjustable headrests only allow for one-way height adjustment, while automatically adjustable ones can adjust in two dimensions automatically.

How does ETC charge?

ETC charging method: Through the on-board electronic tag installed on the vehicle's windshield, dedicated short-range communication is established with the microwave antenna in the ETC lane at the toll station, and background settlement processing is carried out using computer networking technology with the bank. Precautions for using ETC: The ETC transaction sensing area is 8 meters. When encountering a vehicle in front that has stopped, to prevent the ETC device of the front vehicle from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters from the front vehicle to avoid automatic sensing and paying for the front vehicle. The recognition speed for ETC lane passage is 20km/h. If the speed is too fast, the vehicle device information cannot be read, which will also result in a failed charge. Unauthorized disassembly or movement of the OBU device, detachment or loosening of the ETC electronic tag, etc., will cause the electronic tag to fail. It can be sent to the bank where the ETC card was processed or the highway service office for testing. If the loosening or detachment is not man-made, it only needs to be reactivated. When using a debit card to bind with ETC, insufficient balance will also lead to a failed charge. Follow the guidance of on-site staff to go to the manual MTC lane and use cash or card for passage. Poor sensing due to the vehicle's windshield being too thick. Especially for vehicles that have had their windshields replaced after an accident or those with modified front windshields, extra attention is needed.
