Buick car showing ESC maintenance indicates a malfunction in the vehicle's Electronic Stability Control system, which may lead to accidents during turns or on rough roads. The ESC system consists of: 1. Steering sensor; 2. Wheel speed sensor; 3. Yaw rate sensor; 4. Lateral acceleration sensor. The function of ESC is: When the vehicle experiences understeer causing outward skidding or oversteer causing the vehicle to cross the centerline or even spin during quick turns, evasive maneuvers, or avoiding suddenly appearing cars or animals, the system uses computer-controlled engine output and individual wheel braking to eliminate understeer or oversteer, thereby improving driving dynamic stability.

How to Solve the Problem When a Car Battery Won't Charge?

Check if the battery is lacking electrolyte. If the electrolyte has dried up, first add distilled water. After adding enough, do not cover the battery's filler caps. Find a regular 220-volt incandescent bulb and connect it in series with the battery, then connect it to a 220-volt AC power source at home to see if the bulb can light up normally. If the bulb lights up normally, continue supplying power for about 1 minute before disconnecting. Wait a few minutes, then reconnect for another minute. Repeat the previous step three to five times, then connect the battery to the charger and charge it normally for 15 hours.

How to Safely Transport a Gas Cylinder in a Car?

After using the gas cylinder, the valve must be tightly closed to ensure it is completely secured. Never be careless, as safety is no trivial matter. Gas cylinders should not be placed inside the passenger compartment. As hazardous materials, the consequences of an accident during transportation would be unimaginable. Private cars are not recommended for transporting gas cylinders. If it is absolutely necessary, the cylinder must be kept upright and transported only over short distances. To prevent the gas cylinder from shaking during transportation, it can be wrapped and secured with soft materials. While driving, do not exceed the speed limit, avoid crowded public places, and ensure the gas cylinder does not roll around to maintain safety.
