Coasting in neutral is bad for the car. For example, when going downhill for a long time in neutral, the vehicle's own weight will cause the speed to increase continuously, requiring frequent use of the brakes. As the brakes are applied repeatedly, the temperature of the braking system will rise, potentially causing the brake fluid to vaporize. When coasting in neutral, the engine and transmission are disconnected, which eliminates the internal braking effect of the car. If the distance between two cars is short and the leading car stops suddenly, the trailing car, if coasting in neutral, will rely solely on the wheel braking system, increasing the risk of a rear-end collision. To facilitate driving and reduce physical effort for the driver, cars are equipped with power steering and brake assist systems, which require engine power to function properly.

What to Do When the Car Steering Wheel Locks and the Engine Won't Start?

When the vehicle's steering wheel is locked and the engine won't start, you can insert the key, press the brake pedal, then turn the steering wheel left and right while simultaneously turning the car key to complete the steering wheel unlocking procedure. Note that the key won't turn if you don't rotate the steering wheel during this process. The steering wheel lock is a simple anti-theft feature. Parking precautions: 1. Actively check if the vehicle is properly parked: After parking, you should actively observe whether the vehicle is properly positioned. If you forget the number of steering wheel turns, you can check the wheel rotation by looking outside; 2. Do not forcibly straighten the steering wheel: If you notice the tires aren't straight after turning off the engine, remember not to force the steering wheel back to center. You must restart the vehicle before straightening the steering wheel to avoid direct damage to the steering mechanism.

What Causes the Start-Stop Function to Fail?

Here are the reasons why the automatic start-stop function may fail: 1. The battery temperature is too high or too low. 2. The battery charge is too low. 3. The vehicle is on a steep slope. 4. The cabin is being heated or cooled and has not yet reached an acceptable temperature. 5. The engine has not reached its normal operating temperature, or the transmission is not in drive mode. Below is additional information about the engine automatic start-stop system: 1. Definition of automatic start-stop: It is a system that automatically shuts off the engine when the vehicle comes to a temporary stop (e.g., at a red light) and automatically restarts the engine when it's time to move forward. 2. Function: During red lights or traffic jams, the system minimizes engine idling time to reduce unnecessary fuel consumption. Turning off the engine while stopped effectively reduces noise and vibration, providing a better driving experience.

Should You Replace 2 or 4 Tires at a Time?

Tires can be replaced either 2 or 4 at a time. When replacing 2 tires, it's essential to replace the pair on the same axle. Tires are the only components of a car that make direct contact with the ground. Some car owners choose to replace only the tires on the drive wheels. For instance, in front-wheel-drive vehicles, owners might replace only the two front tires, while rear-wheel-drive vehicle owners might replace only the two rear tires. In fact, this practice is acceptable. More details are as follows: 1. Tires are made of rubber and will age over time. It is recommended that car owners replace their tires every four years, even if the mileage is low during this period. 2. Tires can also age when not in use for extended periods, so it's important to check the production date when purchasing new tires.

What lights should be used when passing through an arched bridge slope?

When passing through an arched bridge slope, you should use the high and low beams alternately. According to the Implementation Regulations of the Road Traffic Safety Law of the People's Republic of China, when a motor vehicle passes through sharp curves, slopes, arched bridges, crosswalks, or intersections without traffic signal control at night, it should alternately flash the high and low beams twice as a signal. When a motor vehicle approaches sections such as sharp curves or the top of slopes that affect safe sight distance, or when overtaking or encountering emergencies, it should slow down and sound the horn as a signal. The main challenge of driving at night is poor visibility, so lights must be used. Generally, low beams are sufficient for normal nighttime driving. Turn signals must be used when turning. If you encounter a poorly lit road with insufficient lighting ahead, you should switch to high beams.
