What does the N gear mean in driving?

Driving in N gear means neutral gear, which only exists in automatic transmission models. When the car is in N gear, it loses traction and braking force, and is used when briefly waiting at a red light. Introduction to automatic transmission car gears: 1. P gear: When parking the car, the gear lever must be shifted into P position; 2. R gear: Reverse gear; 3. N gear: Neutral gear, which can be used when starting or towing; 4. D gear: Forward gear, place the gear lever in D position during normal driving; 5. S gear: Sport mode, in this gear the transmission can shift freely, but the shifting timing is delayed to keep the engine at high RPM for a longer time, increasing the vehicle's power; 6. L gear: Low gear, in this gear the transmission stays in 1st gear without shifting up, and can be used on slopes, etc., also providing some braking function when going downhill.

Can the car be driven when the water temperature is too high?

When the car's water temperature is too high, it should not be driven, as this can cause engine damage or even greater losses. Solutions for high water temperature: 1. Pull over to the side of the road, do not turn off the engine immediately, let it idle for a few minutes, and then open the engine hood. 2. Check if the cooling fan is running. If it is not, inspect whether the fan belt is intact and check the belt tension. Both too loose or too tight can cause high water temperature. 3. After the water temperature has dropped, open the radiator cap. It is important to first place a cloth over the radiator cap, slowly unscrew it, and wait until you hear a hissing sound before fully opening it to prevent hot steam or water from spraying out and causing burns. Once the radiator pressure has decreased, add cold water or antifreeze.

What Causes the Squeaking Sound in New Car Brakes?

New car brakes may squeak because the brake pads and discs are new and need to wear in. During this period, the brakes may produce unusual noises, but these will disappear after a few hundred kilometers of driving. In the initial usage phase, the brake discs and pads have not yet fully matched, so during sudden or heavy braking, the brake discs may emit sharp squeaking sounds. This is actually an occasional occurrence and does not affect braking performance. With patient break-in over time, the situation will improve. Brake discs play a crucial role in the braking system. As wear components, brake discs typically need to be replaced along with the brake pads after two sets of pad replacements. Due to differences in manufacturing costs and performance orientations among different car models, the wear rate of brake discs also varies.

What Could Be the Reason for a Car Not Starting?

Reasons why a car may not start: 1. Severe carbon buildup inside the vehicle's engine, leading to difficulty in starting and causing idle vibration; 2. Issues with the vehicle's ignition system—it's necessary to check the spark plugs and high-voltage wires. Abnormal operation of the ignition system can result in such situations, causing idle vibration or difficulty in starting; 3. Unstable fuel pressure in the vehicle's fuel system, where the fuel pump fails to supply fuel properly to the vehicle, leading to poor fuel atomization by the engine or inability to open the fuel injectors, resulting in cylinder misfire vibration or failure to start; 4. Faults caused by insufficient engine cylinder pressure—the vehicle's engine has exceeded its service life and thus cannot continue to operate, leading to intermittent idle vibration. In such cases, prompt repair at a service center is necessary.

Where to Place the Spare Car Key?

Spare car keys are placed in a small shelf on top of the car. This location is very safe and prevents the keys from falling out, making it a good practice for those who prefer to keep spare keys inside the car. This method avoids potential troubles when the keys are forgotten at home or in the car, offering both convenience and safety. Steps to use the spare key: 1. Locate a small rectangular hole at the end of the car handle, pull the handle outward with your left hand, and insert the spare key into the rectangular hole to remove the lock cover; 2. After removing the lock cover, you will see the keyhole—use the spare key to unlock the car door; 3. Pull the door handle outward and align it with the lock cover interface to insert the lock cover.
