During heavy rainstorms, it is advisable to turn on the hazard lights. The correct method to activate hazard lights is to press the red triangle button located on the vehicle's dashboard. The purposes of hazard lights are: 1. To alert other vehicles in case of breakdowns, accidents, or emergencies; 2. To prevent rear-end collisions when parking on the roadside. Situations where hazard lights should be used include: 1. Vehicle breakdown or traffic accident on the road; 2. Parking on the roadside; 3. Driving in foggy conditions; 4. When towing a malfunctioning vehicle, both the towing vehicle and the towed vehicle should turn on hazard lights; 5. Temporary parking on the road; 6. Visibility less than 100 meters; 7. Transporting critically ill patients; 8. Reversing or making U-turns on complex road sections.

During heavy rainstorms while driving, I believe it's best not to use hazard lights (double flashing lights), because hazard lights are originally meant to warn others of vehicle breakdowns or parking. Using hazard lights while moving may make other drivers mistakenly think you've stopped, which can more easily lead to rear-end collisions. In extremely low visibility conditions, using fog lights or low beams is actually more effective, as they can penetrate the rain and fog to help other vehicles see you. At the same time, be sure to slow down to a safe speed, maintain at least three times the normal following distance, and ensure your windshield wipers are on the fastest setting to clear water from the windshield. I've seen too many cars on the road using hazard lights, resulting in a confusing sea of flashing lights where it's hard to tell who's moving, actually increasing the risk. Safety first - if the rain is too heavy and visibility is really poor, it's better to find a place to pull over and rest until the rain lightens up before continuing your journey.

Turning on hazard lights during heavy rain sounds like a good idea, but I once had a close call. Visibility was less than 20 meters, and I turned on my hazards to alert cars behind me. However, others had their hazards on too, and the entire road was filled with flashing lights, making it hard to see the movements of the car ahead. Suddenly, a car thought I had stopped and nearly rear-ended me. Since then, I've switched to using front fog lights and rear tail lights instead, while reducing my speed to around 30 km/h and maintaining an extra-long following distance. It's also crucial to check if the windshield wipers are worn out, as water streaks can impair vision, and to ensure the tires have good traction. The combination of wipers and lights is key. Using hazard lights not only didn't help but also distracted others. It's far better to focus on driving safely.

What to Do When the Front Wheels of a Vehicle Lock Up During Braking?

The solutions for front wheel brake lock-up in a vehicle: 1. Clean or replace the brake caliper; 2. Replace with a qualified brake disc; 3. Conduct a computer diagnosis and repair at a 4S shop based on the fault code. When the brakes lock up, if the tracks of the front and rear wheels are in a straight line, the vehicle moves forward in a straight line. If the tracks of the front and rear wheels are not aligned, the vehicle will skid. To address brake lock-up issues, ABS (Anti-lock Braking System) technology is used. The main feature of this technology is that during emergency braking, the wheels do not stop rotating, ensuring that the vehicle does not experience sliding friction with the ground. This helps maintain control of the vehicle and prevents tire blowouts caused by sliding friction.

What to Do When the Car Takes Several Attempts to Start?

Solutions for when a car takes several attempts to start: 1. Check the battery; if the battery performance is poor, it can cause difficulty in starting. Replace the battery when the voltage difference exceeds two volts. 2. Inspect the spark plugs; spark plugs are wear-and-tear components that need regular replacement. When the electrode gap widens, it affects spark plug ignition, necessitating timely replacement. 3. Check the cleanliness of the throttle valve and clean it promptly. 4. Inspect the carbon canister solenoid valve for cleanliness and clean it if necessary. 5. Replace the fuel filter; it is recommended to change it every 15,000 kilometers. 6. Improve the quality of the fuel used.

What to Do When the Car Maintenance Warning Light Comes On?

When the car maintenance warning light comes on, it indicates that there may be a fault with the vehicle, requiring inspection and repair. Check whether the water temperature and oil pressure are normal, and look for any oil or water leaks, unstable idling, abnormal acceleration, or unusual noises. If a fault is detected, stop the vehicle promptly. If no abnormalities are found, proceed to the nearest repair shop for inspection. Introduction to vehicle maintenance warning lights: 1. Tire Pressure Warning Light: Indicates abnormal tire pressure, requiring immediate tire inspection; 2. Water Temperature Indicator Light: Typically stays on when the car is first started, especially in winter. It features a blue thermometer icon and lights up if the water temperature is too high or too low. If the water temperature is too high, stop the vehicle immediately and wait for it to normalize before heading to the nearest 4S shop or auto repair shop for inspection; 3. Oil Pressure Warning Light: Lights up when oil pressure is abnormal. The oil pressure warning light illuminates when the vehicle starts. If the oil pressure is normal, it will turn off shortly after. However, if the oil pressure remains abnormal, the light will stay on.

When does the car engine fan turn on?

The car engine fan operates based on coolant temperature. Generally, when the coolant temperature reaches approximately 80 to 90 degrees Celsius, the fan starts working. The computer controls its operation upon detecting elevated temperatures to achieve engine cooling. When the coolant temperature returns to standard levels, the fan stops working to maintain normal engine operating temperature. Specifically, when the coolant reaches 95°C, the fan activates and runs at about 1,600 RPM. At 105°C, the fan speed increases to approximately 2,400 RPM to enhance cooling efficiency. Whether the fan operates at idle depends on coolant temperature - it doesn't immediately activate upon cold start idling since the coolant hasn't warmed up yet. Typically, it takes about five minutes for the fan to start running at idle.
