How to Properly Use the Car Air Conditioner on Rainy Days?

Is it okay to shift to N gear and step on the foot brake when waiting at a red light?

Whether to shift to N gear and step on the foot brake when waiting at a red light depends on the situation: Generally, red lights last around 20 to 100 seconds. If you need to wait for a red light for less than 30 seconds, you can stay in D gear without shifting, step on the brake, and release the brake to press the accelerator when the light turns green. If the red light lasts more than 30 seconds, it's better not to stay in D gear; shift from D to N gear and engage the handbrake without stepping on the brake. Temporarily stopping with the brake pressed in D gear won't harm the car because the torque converter in the transmission is equipped with a reaction wheel with a one-way clutch, which amplifies the torque from the engine crankshaft. It doesn't rotate at engine idle speed and only engages when the engine speed increases.

What Causes Severe Engine Vibration?

Generally, the symptoms of engine vibration include: idle vibration and poor acceleration. Severe engine vibration may be caused by 4 reasons: severe engine carbon buildup, ignition system issues, aging engine components, and unstable oil pressure. The specific explanations are as follows: 1. Severe engine carbon buildup causing car vibration: The most common cause is a dirty throttle body or excessive carbon deposits in the fuel injectors. When there is too much carbon buildup inside the engine, the gasoline sprayed by the cold-start injector will be largely absorbed by the carbon deposits, resulting in an overly lean air-fuel mixture during cold starts and making it difficult to start. In this situation, the engine will only start easily once the carbon deposits have absorbed enough gasoline to become saturated. After starting, the gasoline adsorbed on the carbon deposits will be drawn into the combustion chamber by the engine's vacuum suction, causing the air-fuel mixture to become too rich. This fluctuation between lean and rich mixtures leads to idle vibration after a cold start. In such cases, the fuel system should be cleaned, and the idle control valve should be checked for carbon buildup and cleaned immediately if necessary. 2. Ignition system issues: Check the condition of the spark plugs, high-voltage wires, and ignition coils. Poor performance of the ignition system or weak spark plug firing can also cause such issues. At this time, check if the spark plugs have excessive carbon buildup and replace them if necessary. 3. Aging engine components: Car engine vibration can also be related to aging engine mounts (also known as engine mounts). Engine mounts are essentially the engine's shock absorption system, responsible for absorbing minor vibrations during operation. If the engine mounts are faulty, these vibrations will be transmitted to the steering wheel and the cabin, causing idle vibration. In such cases, the components should be replaced. 4. Unstable oil pressure: If the fuel pump's supply pressure is abnormal or the intake pressure sensor's readings are incorrect or malfunctioning, it can lead to engine vibration. In this case, check the oil pressure and replace components if necessary.

What does 'auto' mean on Volkswagen cars?

Volkswagen cars' 'auto' refers to automatic air conditioning. In automobiles, 'auto' generally means automatic transmission shifting. Volkswagen vehicles have an 'auto' switch in the air conditioning control area, indicating automatic climate control - this allows drivers to set a comfortable temperature using the temperature adjustment knob. There's also an 'Autohold' function representing automatic parking brake, which eliminates the hassle of manual gear shifting and clutch operation from stationary position to acceleration. Volkswagen is an automobile manufacturer headquartered in Wolfsburg, Germany. The name 'Volkswagen' translates to 'the people's car'. The company's logo has undergone several changes throughout history, with the 'VW' letters representing the initials of its full name. The current emblem appears to consist of three 'V's formed by middle and index fingers.

Which One is the Brake and Which One is the Accelerator?

In automatic transmission models, the left pedal is the brake and the right pedal is the accelerator; in manual transmission models, the middle pedal is the brake and the right pedal is the accelerator. Since automatic transmission models do not require manual gear shifting and the car shifts gears automatically, there is no clutch pedal, only the accelerator and brake, both controlled by the right foot. During driving, the left foot should not be placed on the brake pedal. There are two main reasons for this: 1. During long drives, both feet can become quite tired, leading to unintentional pressing. If the left foot is on the brake pedal at this time, pressing it could easily cause an accident and pose a danger; 2. Most people are right-handed, and the right foot reacts faster. In case of an emergency, the right foot can quickly respond by lifting off the accelerator and pressing the brake pedal.
