How to Use Hazard Lights in a Car?

When the water level reaches above 20 centimeters, there is a risk of water entering the engine. For ordinary sedans, when the water level exceeds 20 centimeters (for SUVs with higher ground clearance, this threshold increases to 30 centimeters), the risk of engine water ingress arises. Water can enter the engine through two main pathways: 1. Low air intake inlet: Due to the low position of the engine's air intake inlet, water can be sucked into the engine when driving through flooded areas. 2. Exhaust outlet below the waterline: If the exhaust pipe outlet is submerged below the waterline, water can be drawn into the engine through the exhaust. Here is relevant information: 1. Engine stalling is inevitable after water ingress: Since water entering the cylinders lacks lubrication, attempting to restart the engine blindly after stalling may cause severe damage (e.g., cylinder scoring), potentially leading to engine failure. The correct approach is to push the car to a higher, non-flooded area, contact your insurance company, and have the vehicle towed to a repair shop for inspection. 2. Check all fluid systems in the vehicle: After water exposure, fluids may foam or become contaminated, losing their lubricating properties. Additionally, water may carry sand particles, accelerating engine wear. Therefore, prompt cleaning and fluid replacement are necessary. After inspection, thoroughly clean electrical connectors in the engine compartment to prevent corrosion and sand residue. Key areas to clean include the fuse box, sensor connectors, and areas where water may accumulate in the body. Once these components are cleaned, conduct a road test at moderate speeds while carefully listening for abnormal engine noises. If unusual sounds are detected, inspect engine bearings and rotating components again to prevent damage from excessive wear.
The car hazard lights are the red triangle button on the dashboard. In emergency situations, pressing it once will activate them, causing all turn signals to flash simultaneously to alert vehicles in front and behind. After use, press the same button again to turn them off. I often use them in specific scenarios while driving, such as when the car breaks down and is parked on the roadside or during minor accidents, turning them on immediately to protect myself and others. In low-visibility conditions, such as heavy fog or rainstorms, turning on the hazard lights allows other drivers to spot your position from a distance, reducing the risk of rear-end collisions. Remember, after activating the hazard lights, avoid moving the car too far, as this constitutes abnormal driving behavior and may lead to traffic violations. Regularly check the button's responsiveness and ensure the lights function properly to maintain driving reliability.
