How to Start the Car in Driving Test Subject 3?

The method to start the car in Driving Test Subject 3 is: 1. After hearing the voice prompt to start, depress the clutch; 2. Shift the gear into first gear; 3. Turn on the left turn signal, which will be displayed on the dashboard; 4. Simultaneously observe the left rearview mirror, confirm safety, and honk the horn; 5. Release the parking brake, start smoothly, and turn off the turn signal. Before starting, observe first. When the conditions are suitable for starting, release the clutch. At this time, you won't be nervous due to incoming and outgoing vehicles affecting your operation, and you can start slowly. The method of using gears in a manual transmission is: 1. Start in 1st gear; 2. Use 2nd gear between 20 to 40 km/h; 3. Use 3rd gear between 40 to 60 km/h; 4. Use 4th gear between 60 to 75 km/h; 5. Use 5th gear above 75 km/h; 6. Reverse gear is used for backing up.

Is It Good to Step on the Gas Pedal Hard When Starting a Car?

Stepping on the gas pedal hard when starting a car can cause significant damage to the vehicle. Frequently accelerating aggressively from a standstill does more harm than good, especially to the car's engine and transmission. Here are the relevant details: 1. During rapid acceleration, the engine's RPM suddenly increases, causing the engine pistons to operate at high speeds. Theoretically, this also generates substantial impact on components such as the engine crankshaft and cylinder walls. 2. The transmission interacts with the engine, and its interior consists of various gears and components. During rapid acceleration, the sudden generation of high torque places greater pressure on parts like the steel belt gears and clutch. Friction between transmission components can easily produce fine metal shavings, leading to impurities in the engine oil. This is why new cars require an oil change during their first maintenance.

How to Turn Off a Mercedes-Benz Car?

There are four steps to turn off a Mercedes-Benz car: 1. Shift the gear to N (Neutral) and engage the electronic parking brake. 2. Continue to press the foot brake and shift the gear from N to P (Park). 3. Release the foot brake and press the one-touch start button. 4. The power turns off, completing the shutdown process. Before turning off a Mercedes-Benz car, pay attention to the following four points: 1. Ensure the vehicle is safely and steadily stopped before turning it off, and make sure the car won't slide before shifting the gear lever. 2. Straighten the steering wheel before turning off the car. A misaligned steering wheel keeps the car's steering system under stress, which can cause deviations in wheel alignment. 3. Choose an appropriate parking location before turning off the car. 4. Turn off the air conditioning before shutting down the car. If the air conditioning is left on when turning off the car, the car's power will surge when starting, affecting the startup process.

What does 10w-40 mean for engine oil?

10w-40 refers to the SAE standard viscosity value of the engine oil. Here are the relevant explanations: 1. The number after W represents the kinematic viscosity of the oil at 100℃. The higher the number, the higher the viscosity. 2. The oil grade includes two parts: classification and viscosity specification. The oil grade usually indicates viscosity and quality. 3. W stands for winter. The smaller the number before it, the better the low-temperature fluidity of the oil, indicating a lower usable environmental temperature and better protection for the engine during cold starts. The number after "W" (after the hyphen) is an indicator of the oil's high-temperature resistance. The larger the number, the better the oil's protective performance at high temperatures.

How to Clear a Clogged Exhaust Pipe?

From a design perspective, exhaust pipes cannot be cleaned; severe blockages require complete replacement. Effects of a clogged exhaust pipe: 1. Insufficient power, slow acceleration: Exhaust gases cannot exit, and fresh air cannot enter, leading to inadequate combustion and reduced power. 2. Increased forced downshifts in automatic transmission vehicles: A clogged exhaust pipe reduces engine power, prompting the driver to press the accelerator. However, the ECU will automatically force the transmission to downshift based on the throttle position. 3. Difficulty starting the engine: Even with a charged battery, proper fuel injection, and normal compression pressure, the engine may fail to start because fresh air struggles to enter. 4. Rattling noises from the exhaust system during hard acceleration or emergency braking. In most cases, the primary cause of exhaust pipe blockage is a neglected catalytic converter. Maintenance of the catalytic converter: 1. Use unleaded gasoline: The catalytic converter is highly sensitive to lead. Leaded gasoline can cause blockages. 2. Regular maintenance: Clean the throttle body every 10,000 kilometers. If performance remains poor after cleaning, the catalytic converter may need cleaning.

What causes the car to shake when accelerating?

The reasons why the car shakes when accelerating are as follows: 1. It may be due to unstable engine operation, and carbon deposits should be cleaned. 2. If the steering wheel shakes, check whether the cooling fan is loose or has other issues, as well as the ball joints and tie rod ends. After inspection and replacement, a four-wheel alignment should be performed; otherwise, the gear may not engage. 3. Check the engine mounts: Inspect the engine mounts and the installation of the air conditioning compressor for any looseness. 4. Low idle speed may also be caused by the engine not receiving the air conditioning activation signal, or the air conditioning activation signal voltage may be too weak to increase the engine speed, leading to engine shaking under heavy load.
