When the vehicle stops moving due to traffic congestion or at an intersection, the driver should press the brake pedal, come to a complete stop, and shift to neutral. The Start/Stop system automatically checks: the engine is idling and not in gear; the wheel speed sensor shows zero; the vehicle has sufficient battery power. Once these three conditions are met, the engine will automatically stop. When the traffic light turns green, the driver can press the clutch pedal to immediately activate the AOFF function.

The A OFF button in cars is actually the switch for the auto start-stop function! This feature automatically activates every time you start the car. When you brake at a red light, the engine shuts off to save fuel and reduce emissions. However, some drivers find the restarting motion uncomfortable or worry about potential issues when driving through water in rainy conditions. In such cases, pressing the button on the center console with the letter A inside a circle can completely deactivate it. Personally, I prefer to toggle it flexibly based on road conditions – keeping it on during congested commutes saves a lot on fuel costs, while turning it off on highways helps reduce wear and tear. Remember, if you choose to keep it off long-term, you'll need to manually disable it every time you start the car!

What are the causes of difficult engine starting and how to deal with it?

Reasons and solutions for difficult engine starting: 1. Overly rich air-fuel mixture: If the engine is difficult to start when hot, but can start normally when the accelerator pedal is fully depressed (no fuel injection when fully depressed), it indicates an overly rich mixture. In this case, remove the air filter element to release some of the accumulated rich mixture in the intake tract. 2. Excessive carbon deposits in the throttle system and bypass air passage: If the accelerator pedal feels much heavier than usual when first pressed each day, and the engine is difficult to start, but starts normally when the pedal is slightly depressed, it indicates excessive carbon deposits in the throttle. However, the engine may stall immediately when the accelerator pedal is released while driving. The throttle system and bypass air passage should be cleaned promptly, and recalibrated after cleaning to restore normal operation. 3. Excessive carbon deposits in the combustion chamber: During the first start each day, it may require 2-3 consecutive starts (as the initial fuel is absorbed by carbon deposits). In severe cases, sudden and intense shaking may occur, even causing the entire vehicle to shake. Clean the combustion chamber carbon deposits, and drive at high speed for 20 minutes after cleaning to resolve the issue.

What Causes Loud Tire Noise?

Tire noise is primarily caused by vibrations generated when the tire comes into contact with and rubs against the road surface. Below is a detailed explanation: On roads with varying degrees of roughness, the sources of vibration may differ. For instance, most daily driving roads are relatively rough. These rough surfaces are the main source of tire noise. When driving on smooth asphalt roads, the vibration produced by the contact between the tire tread blocks and the road surface becomes the primary source of noise, due to the various tread patterns on the tire surface. Additionally, tire noise is also related to the material of the tire. The harder the tire material, the louder the tire noise.

What is the purpose of the shark fin on the car roof?

The functions of the shark fin on the car roof are as follows: 1. Intercepting radio waves: The car antenna intercepts high-frequency radio waves, enabling the reception of radio signals. 2. Releasing static electricity: It can discharge static electricity from the small tail, preventing people from getting shocked, as the antenna has the function of discharging static electricity. 3. Enhancing signals: In many remote areas where the signal is poor and radio reception is not ideal, this antenna can improve radio signal reception, providing a better listening experience. 4. Aerodynamic spoiler: While driving, it helps overcome air resistance, reducing interference on the car, which results in lower fuel consumption.

What is the maximum tire size that can fit on 18-inch rims?

Normally, 18-inch rims have a width of 7.5 inches, and the most suitable tire width is 225mm, with a maximum usable width of 235mm. More information about car tire sizes is as follows: 1. The specifications and parameters of car tires are expressed in millimeters for the section width and the percentage of the aspect ratio. This is followed by: tire type code, rim diameter (in inches), load index (code for permissible load capacity), and permissible speed code. 2. Rims and tires with larger widths are not suitable for civilian vehicles. This is because wider tires create significant rolling resistance, requiring the vehicle to have sufficient horsepower to drive normally.
