The red battery charger connects to the positive terminal, while the negative terminal is black. Car owners must ensure correct connection during wiring, as reversing the polarity may damage all electronic devices in the vehicle. The battery is a crucial automotive component that powers all electronic systems and starts the engine when it's off. After engine ignition, the alternator takes over powering the electronics while simultaneously recharging the battery. The starter motor draws substantial current during operation - inadequate battery performance will cause insufficient starter rotation, preventing proper engine startup. Battery capacity naturally degrades with charge/discharge cycles, making it a regularly replaced wear item.

Will the wheel hub deform after driving two kilometers with a flat tire?

Whether the wheel hub deforms after driving two kilometers with a flat tire depends on different situations: 1. If the driving speed is relatively slow and on a relatively flat road surface, it will not cause the wheel hub to deform; 2. If the driving speed is relatively fast and the road surface is uneven, it may cause the wheel hub to deform. The causes of a flat tire are: 1. Overloading; 2. Speeding; 3. Poor road conditions; 4. Unqualified tire pressure; 5. Internal damage to the tire or bubbles in the tire cord layer; 6. Excessive wear on the tire surface or corrosion by oil; 7. High temperatures. The methods to handle a flat tire while driving are: 1. Hold the steering wheel firmly with both hands and try to control the car; 2. Pay attention to the vehicles behind, brake slowly, and move away from the main road; 3. Do not brake suddenly to avoid the vehicle skidding or overturning due to uneven braking force; 4. Place the triangular parking board on the road behind the vehicle when parking; 5. Replace the spare tire as soon as possible.

Which Side is the Car Brake?

Car brake positions vary depending on the situation: 1. For manual transmission vehicles, the brake is in the middle; 2. For automatic transmission vehicles, the brake is on the left. The main functions of car brakes are: 1. To decelerate and stop the vehicle; 2. To keep a parked car stable on various road conditions; 3. To maintain a stable speed when driving downhill. Methods for using car brakes include: 1. Lightly tapping the brake on bumpy or complex road sections to avoid damaging the car chassis due to excessive speed; 2. Slightly releasing the brake before the vehicle comes to a complete stop, then gently pressing it again to bring the vehicle to a halt; 3. Using lower gears to utilize engine braking when going downhill for long distances to avoid continuous brake application; 4. Applying the brake before entering a curve to slow down and avoid losing balance and skidding.

How to Remove Cement Dust Stuck on the Car?

Methods to remove cement dust stuck on the car include: 1. If the cement has not hardened yet, it can be directly rinsed off with clean water; 2. If the cement has already hardened, white vinegar or a specialized cement cleaner can be sprayed onto the cement. After the cement softens, rinse it off with plenty of water; 3. If the cement cannot be rinsed off completely or the car paint has scratches, it can be handed over to an auto beauty shop for treatment; 4. Pour gasoline over the cement and wait for the paint to soften, then manually remove the cement; 5. Use a hairdryer to heat the area with cement. Due to the different thermal expansion rates of cement and plastic, the cement may fall off automatically; 6. Use sand wax and a polishing wheel for treatment.

What is the technique to completely disable the auto start-stop function?

The technique to completely disable the auto start-stop function is: 1. Expose the car to direct sunlight until the displayed temperature exceeds 35 degrees Celsius; 2. Open the interface for deactivating the engine auto start-stop function; 3. Manually turn on the switch and long-press the engine auto start-stop deactivation icon until the small yellow bar disappears. The auto start-stop system is a set of systems that automatically shuts off the engine when the vehicle comes to a temporary stop during driving and automatically restarts the engine when it's time to move forward again. Precautions for using the auto start-stop system include: 1. Turn off the auto start-stop system when using the air conditioning; 2. Turn off the auto start-stop system in heavy traffic; 3. Turn off the auto start-stop system during low-speed parking; 4. Turn off the auto start-stop system before wading through water; 5. Do not use the auto start-stop system when driving uphill.
