Driving in heavy rain does not require turning on hazard lights. Here is the relevant information: 1. Hazard Lights: Hazard lights, also known as emergency flashers, are signal lights used to alert other vehicles and pedestrians that your car is experiencing a special situation. From this definition, it can be seen that hazard lights should be used in emergencies to signal approaching vehicles to slow down or stop. 2. When the Vehicle Breaks Down: If your vehicle breaks down on the road and cannot be moved to a safe area promptly, you should immediately turn on the hazard lights to alert passing vehicles and pedestrians for safety, call for help, and wait for rescue.

Turning on hazard lights is not a standard practice when driving in heavy rain. Unless you genuinely need to make an emergency stop or your vehicle has a malfunction, using hazard lights while driving normally can mislead other drivers about your intentions; they might think you're about to turn or stop, increasing the risk of rear-end collisions or side swipes. A more effective approach is to turn on your position lights, low beams, and fog lights—these are specifically designed for adverse weather conditions and help maintain visibility. I've experienced several heavy rainstorms and noticed that cars using hazard lights on the road often cause confusion; it's advisable to reduce speed to a safe limit, maintain a following distance at least twice the usual length, and keep at least 80 meters from the vehicle ahead when driving below 60 km/h. Checking tire pressure and ensuring wipers function properly can reduce skidding. Safety comes first—only use hazard lights as an emergency warning.

When driving in heavy rain, should you turn on the hazard lights? From a practical standpoint, I don't think using them necessarily increases safety. Hazard lights are meant to indicate a parked or malfunctioning vehicle. Using them while driving can confuse others—are you turning, braking, or just driving normally? This can actually divert attention and increase the risk of accidents. As someone familiar with vehicle operations, I recommend using the parking lights, low beams, or dedicated fog lights to enhance visibility. Additionally, control your speed—don’t exceed 80% of the road’s speed limit—and increase your following distance, such as maintaining a 100-meter gap in heavy rain. Don’t forget to set the car’s air conditioning to external circulation to defog the windows. Once, I tried using hazard lights in the rain and was misunderstood by a nearby driver, nearly causing an accident. The key is to only use hazard lights in genuine emergencies.

What to Do When the Manual Gear Shift Lever Has Excessive Play?

Manual gear shift lever has excessive play solution is: 1. If the gap between the shift lever and surrounding rubber is too large, you can add a nylon sleeve in the original position to reduce the gap to normal range; 2. If the excessive shift play is caused by severe wear of the handle ball head, first replace the entire handle shift mechanism, then adjust the length of the gear shift cable and shift cable. The shift lever, also known as the operating lever, is used in the car transmission, its main function is to support the car's gear shifting. The shift lever is a rod component, the five-speed shift lever generally integrates the reverse gear function, and the shift fork and shift shaft fork need to be installed on the shift lever to achieve its functional combination.

What Causes the Deafening Resonance Sound Inside a Car Cabin?

The causes of deafening resonance sound inside a car cabin include: 1. Some enclosed spaces within the cabin form resonant cavities at specific fixed frequencies, which can cause resonance phenomena at certain frequency points; 2. Certain panels in the vehicle have special resonance points, such as the roof steel plate and front/rear door panels. Due to their thin steel material, relatively large surface area, and particular shapes, they may form resonance points at specific frequencies; 3. Loose installation of certain items in the cabin, such as audio systems. Generally, noises in the cabin can be categorized into various types, including mechanical noise, tire noise, and wind noise. Additionally, noise within the limited space of a vehicle consists of both direct noise and reflected noise. Sound absorption involves using special passive materials to alter the direction of sound waves and absorb their energy. Managing resonance noise in vehicles primarily targets mechanical sounds in the engine compartment and rear-end resonance noise. Proper arrangement of sound-absorbing materials can effectively reduce the reflection of sound energy, achieving the purpose of sound absorption and noise reduction.

How to Get Rid of Cockroaches in a Car?

Solutions for cockroaches in a car: 1. Cockroach spray: Spray cockroach spray into the corners of the car, then close the windows and wait for a day to kill the cockroaches. However, this method is not long-lasting, and chemical products are somewhat harmful to the human body. Note that after using the spray, ensure proper ventilation before entering the car, and clean up the dead cockroaches. 2. Cockroach bait or gel bait: Place some cockroach bait or gel bait in areas where cockroaches might appear, such as door gaps, under seats, or in the trunk, to act as a lure. Be cautious to prevent children from touching or ingesting it.

The Corolla is a compact sedan under the Toyota brand, with the latest top model being the 2021 Hybrid 1.8L E-CVT Flagship Edition. Different sizes: The Vios measures 4435mm in length, 1700mm in width, and 1490mm in height, with a wheelbase of 2550mm. The Corolla measures 4635mm in length, 1780mm in width, and 1455mm in height, with a wheelbase of 2700mm. Different suspension systems: The Vios uses a torsion beam non-independent rear suspension. The Corolla uses an E-type multi-link independent rear suspension. Taking the Vios 2021 1.5L Manual Xing Edition as an example: it is a compact car under FAW Toyota, equipped with a 5-speed manual transmission. Different models: The Vios is classified as a compact sedan, while the Corolla is a compact sedan, one level higher than the Vios, offering advantages in space, power, and configuration. The Vios is positioned one level below the Corolla, with only 1.3L and 1.5L naturally aspirated engine options, paired with a 5-speed manual or CVT transmission, and is positioned as a compact sedan.

Is Coolant Overflow Related to the Thermostat?

Coolant overflow is not related to the thermostat. It is generally associated with blockages or poor flow in the upper water chamber of the radiator or the return hose from the upper part of the thermostat to the expansion tank. This happens because the coolant in the lower water chamber of the radiator and the water pump inlet pipe is in a negative pressure state. If the throttle is suddenly released or the engine is shut down, the water pump's efficiency decreases or stops working. There are two scenarios where the car does not overheat but the coolant reservoir overflows: 1. Coolant overflow occurs when the accelerator is pressed hard. This is mainly due to large gaps or cracks in the wet cylinder liners or cylinder head. During engine operation, the pressure of compressed air or combustion gases in the cylinders exceeds the pressure of the coolant in the cooling passages, allowing these combustible gases to enter the engine's cooling passages through the gaps, resulting in coolant overflow from the reservoir. 2. No air is present in the coolant during engine operation. Whether the coolant temperature is high or low, pressing the accelerator does not cause coolant to spray out from the filler cap, but releasing the accelerator causes coolant to spray out from the filler cap.

How to Solve Rearview Mirror Vibration?

There are two solutions for rearview mirror vibration: 1. Center rearview mirror: Adjust the left and right positions so that the left edge of the mirror just cuts off your right ear in the reflection, and adjust the up and down positions to place the distant horizon at the center of the mirror. 2. Adjust the side rearview mirrors: For the left mirror, position the distant horizon at the center for up and down adjustment, and adjust the left and right positions so that the car body occupies one-quarter of the mirror. For the right mirror, when adjusting the up and down positions, ensure a larger ground area, about two-thirds of the mirror, and similarly adjust the left and right positions so that the car body occupies one-quarter of the area.
