When the Auto Start-Stop Light is On, Is the Auto Start-Stop Function Turned Off or On?

When the auto start-stop light is on, the auto start-stop function is turned off. Here are the relevant details: 1. The engine auto start-stop system automatically shuts off the engine when the vehicle comes to a temporary stop during driving and restarts it when it's time to move forward again. 2. When you first start the car, the auto start-stop function is enabled by default, and the light is off. Pressing the button turns on the light, indicating that the auto start-stop function is disabled. When auto start-stop is turned off, the dashboard will display a warning: a yellow light with the start-stop symbol (a circle with an 'A') and the letters 'OFF' below it, indicating that the auto start-stop is deactivated. The display may vary depending on the car model—some models show a circle with an 'A' and a slash through it. 3. Every time the car is restarted, the auto start-stop function defaults to being enabled; it is not permanently disabled with a single press.

How to Turn Off the Engine with Keyless Start?

Here are the steps to turn off the engine after keyless start: Step 1: Press the brake pedal and bring the vehicle to a complete stop; Step 2: Shift the gear from D (Drive) to N (Neutral); Step 3: Engage the parking brake (pull up the electronic parking brake if equipped); Step 4: Release the foot brake but do not turn off the power (this is to confirm the vehicle is completely stationary under the parking brake's effect and prevent P-gear lock); Step 5: Continue pressing the foot brake and shift the gear from N to P (Park); Step 6: Release the foot brake, press the engine start/stop button to turn off the power and complete engine shutdown.

What are the symptoms of shock absorber oil leakage in a car?

Oil leakage in car shock absorbers can cause symptoms such as bumpy rides and shock absorption failure. As one of the most vulnerable components during vehicle use, the performance of shock absorbers directly affects the smoothness of driving and the lifespan of other mechanical parts. Here are methods to check whether the shock absorber is functioning properly: 1. After driving the car for 10 kilometers on rough road conditions, stop and touch the shock absorber housing with your hand. If it's not hot enough, it indicates there's no internal resistance in the shock absorber, meaning it's not working. At this point, you can add appropriate lubricating oil and test again. If the housing becomes hot, it means there's insufficient oil inside the shock absorber; otherwise, it indicates the shock absorber has failed. 2. Press down hard on the bumper and then release it. If the car bounces 2-3 times, it shows the shock absorber is working well. 3. When performing an emergency brake during slow driving, if the car vibrates violently, it indicates there's a problem with the shock absorber.

What is the purpose of cleaning the car's three-way catalytic converter?

Cleaning the three-way catalytic converter not only helps improve the performance of the vehicle's engine but also reduces frequent alarms from the exhaust system's oxygen sensor. The cleaning cycle for the three-way catalytic converter: 1. Typically, it needs to be cleaned every 30,000 kilometers driven. 2. When you notice increased fuel consumption or reduced power in the vehicle, it's necessary to check and clean the three-way catalytic converter as needed. 3. Every time the vehicle undergoes cleaning of the fuel injectors, throttle valve, and intake tract maintenance, the three-way catalytic converter should also be cleaned. 4. It's best to clean the three-way catalytic converter before the annual exhaust emission test, otherwise, the vehicle may not pass.

What to Do When Car Tire Pressure is Too Low?

Tire pressure too low: If you have an onboard air pump, you can first inflate the tire a little and then slowly drive to the nearest repair shop for further handling, or replace it with a spare tire before going for repairs. Below are relevant explanations about low tire pressure: 1. When a car's tire pressure is too low, the most obvious phenomenon is an increase in the vehicle's fuel consumption. 2. Because low tire pressure increases the friction between the car's tires and the ground, the running resistance increases, leading to higher fuel consumption. At the same time, the tire's movement will also increase, as the increased friction will raise the tire's temperature, causing it to soften and thus reducing its usage strength. 3. If driving at high speeds for a long time, it may even lead to a tire blowout, threatening driving safety. 4. The reasons for low tire pressure can generally be divided into three categories: first, thermal expansion and contraction due to low temperatures; second, air leakage from the tire; and third, the tire may be improperly installed or the tire edge may not be properly fitted with the rim, resulting in poor tire sealing.

What Are the Routine Maintenance Items for Sedans?

Routine maintenance items for sedans are as follows: 1. Check tire pressure. If the pressure is too low, inflate the tires; if the pressure is too high, release some air. 2. Inspect the vehicle chassis for any oil leaks or loose screws. After long-distance driving, rubber bushings or oil seals under the vehicle may age, leading to oil leaks. Pay special attention to the rubber bushings on the half-shafts, suspension ball joints, and the edges of the transmission for any signs of oil seepage or aging. 3. Change the engine oil. After prolonged use, engine oil tends to degrade, losing its lubricating properties and becoming cloudy. Therefore, it's necessary to drain the old oil and replace it with fresh oil. 4. Clean or replace the air filter. The air filter ensures that only clean air enters the engine. Over time, dust and impurities in the air can clog the filter, reducing its efficiency. Decide whether to clean or replace the filter based on the amount of accumulated dust. 5. Check the brake fluid, coolant, windshield washer fluid, and antifreeze. These fluids may deplete over time due to driving and engine operation. If their levels are below normal during maintenance, they must be topped up. 6. Inspect the brake pads. Use a ruler or visually check for wear on the brake pads. If severe wear is detected, replace the brake pads promptly to avoid brake failure.
