What Are the Reasons for the Sudden Loss of Sound in the Envision's Audio System?

Can the car window be opened if the car falls into water?

No, opening the window would allow water to rush in, and failing to escape in time could lead to drowning. Additionally, the pressure difference between the inside and outside increases the friction between the glass and the window frame, making it very difficult to open the window. 1. Correct approach: When the water levels inside and outside the car are unequal, the car door cannot and should not be opened immediately. You must wait until the water levels inside and outside the car equalize before opening the door. It is also advisable to keep a window-breaking hammer inside the car for emergencies. 2. Principle: When a car falls into water and the water levels inside and outside are unequal—meaning the water level outside is higher than inside—the difference in water pressure between the inside and outside will create immense force, pressing the door shut. This makes it impossible to open the door. Even if you manage to open it, water from outside would immediately flood the car, trapping the occupants and causing the vehicle to sink rapidly.

Can I eat before the driving school physical examination?

Yes, fasting is not required for the driver's license physical examination. The driver's license physical examination should comply with the requirements of the national and local management authorities, and actively complete the relevant inspections. Physical examination requirements: Height: According to the latest Ministry of Public Security Order No. 139, there is no height requirement for Class C driver's licenses. For large passenger vehicles, tractors, city buses, large trucks, and trolleybuses, the height requirement is above 155 cm. For medium-sized passenger vehicles, the height requirement is above 150 cm. Monocular vision impairment: If the better eye has a naked or corrected visual acuity of 5.0 or above on the logarithmic visual acuity chart and the horizontal visual field reaches 150 degrees, a Class C driver's license can be applied for. (Note: Previously, monocular vision was not allowed for a driver's license, but the latest Ministry of Public Security Order No. 139 allows application if the above requirements are met.) Hearing: The ability to distinguish the direction of sound sources with each ear at a distance of 50 cm from a tuning fork. Hearing aids are allowed for those with hearing impairments. Lower limbs: Both lower limbs must be sound and have normal motor function, with a length difference not exceeding 5 cm. However, if the left lower limb is missing or has lost motor function, a driver's license for small automatic transmission vehicles can be applied for. Right lower limb and both lower limbs: If the right lower limb or both lower limbs are missing or have lost motor function but the person can sit independently and the upper limbs meet the requirements of Item 6, a driver's license for small automatic transmission passenger vehicles for the disabled can be applied for. If one hand is missing but the other hand has a sound thumb and at least two other sound fingers, with normal upper limb and finger motor function, and the lower limbs meet the requirements of Item 7, a driver's license for small automatic transmission passenger vehicles for the disabled can be applied for. Vision: 1. For Class C driver's licenses, the naked or corrected visual acuity of both eyes must be 4.9 or above. Color vision: No red-green color blindness is allowed. Upper limbs: Both thumbs must be sound, and each hand must have at least three other sound fingers, with normal limb and finger motor function. However, if the fingers are missing at the distal segment or the left hand has three sound fingers and both palms are intact, a driver's license for small cars, small automatic transmission cars, low-speed trucks, or three-wheeled cars can be applied for. (Note: The upper limb requirements are also an important part of the latest reforms.) Torso and neck: No motor dysfunction is allowed. The following physical conditions disqualify an applicant from obtaining a driver's license: Having used or injected drugs within the past three years, or having been released from compulsory isolation detoxification for less than three years, or being addicted to long-term use of dependent psychotropic drugs and not yet having quit. Having organic heart disease, epilepsy, Meniere's disease, vertigo, hysteria, Parkinson's disease, mental illness, dementia, or other neurological diseases that affect limb movement and hinder safe driving.

Is the car okay if it didn't stall while wading through water?

Stalling or not is not an absolute indicator. It is recommended to conduct an inspection. If the car didn't stall, it indicates the water wading wasn't too severe. Check the air filter, fuel filter, and battery for any signs of water ingress or moisture. Replace them promptly if necessary. Also, inspect whether the transmission has taken in water. If so, replace all the lubricating oil. Additional information: 1. Do not restart immediately if the car stalls unexpectedly: If the car stalls unexpectedly in water, do not attempt to restart it immediately. Instead, take measures to tow the car to a safe location with less water as soon as possible. Water entering the engine is a very serious issue. Water can enter through the air filter into the intake valve and then into the cylinder block via the intake pipe. Under no circumstances should you try to restart the engine at this point. 2. Remove brake pad moisture promptly: After wading through water, it is essential to remove moisture from the brake pads promptly, especially for vehicles with drum brake systems. Failure to do so may result in loss of braking power after wading, leading to severe hazards or accidents.

What are the incorrect emergency measures when a tire suddenly bursts while driving?

Incorrect emergency measures when a tire suddenly bursts while driving: 1. Apply emergency braking to stop the vehicle in the shortest time possible. Avoid sharply turning the steering wheel or applying emergency braking when the tire bursts, as this can easily cause the vehicle to skid or roll over. Generally, when a tire bursts at high speed, the vehicle will rapidly veer toward the side of the burst tire. If not handled calmly with appropriate steering correction, the vehicle may lose control, swaying dangerously on the road. Correct operation is crucial: firmly grip the steering wheel and use intermittent braking (pump the brakes). 2. If a tire bursts while driving, do not leave the vehicle in the middle of the road. The correct procedure is to turn on the right turn signal, slowly move the vehicle to the roadside, set up a warning sign, and call for a tow truck or change to the spare tire. If the vehicle cannot be moved, turn on the hazard lights and set up a warning sign.

Why is the car air conditioning not heating?

There are two main reasons why the car air conditioning is not heating: 1. Engine cooling system failure; 2. Poor operation of the heating control mechanism. During maintenance, it is necessary to first determine which aspect is causing the problem before performing corresponding repairs. Car air conditioning refers to the air conditioning device installed in the vehicle, which can cool, heat, ventilate, and purify the air inside the cabin, providing a comfortable riding environment for passengers, reducing driver fatigue, and improving driving safety. Car air conditioning generally includes refrigeration devices, heating devices, and ventilation devices. This integrated system makes full use of the limited space inside the vehicle, with a simple structure and easy operation, making it an internationally popular modern car air conditioning system.
