In an automatic transmission, both the brake pedal and the accelerator pedal are controlled by the right foot. Here are the specific details about automatic transmissions: Regulation: Automatic transmission models only have two pedals—the brake pedal and the accelerator pedal—both controlled by the right foot. The left foot should rest on the left-side footrest to maintain body balance. However, in practice, some drivers use their left foot for the brake and their right foot for the accelerator, which is an incorrect driving habit. Requirement: Automatic transmissions are designed to be operated solely with the right foot. Yet, some drivers use their left foot for braking and right foot for acceleration, a habit that may lead to accidentally pressing both pedals simultaneously. The brake pedal and accelerator pedal differ in height, and experienced drivers on 58 Auto can quickly distinguish between them by feel.

Oh, this is a topic I often discuss with friends. In an automatic transmission car, the left foot pedal simply doesn't exist—really, because automatic cars simplify driving operations. Manual transmission cars have a clutch pedal that requires left foot operation, but in automatic cars, that function is taken over by the computer, leaving only two pedals on the right side: the brake and the accelerator. When I first learned to drive with a manual transmission, switching to automatic made my left foot feel oddly idle, but I got used to it quickly. For beginners driving automatic cars, I recommend focusing on right foot control and not mistakenly thinking the left side needs operation—that can lead to errors and is unsafe at high speeds. The biggest advantage of automatic transmission is the convenience for city commuting, avoiding the exhausting clutch pedal work in traffic jams, thus enhancing driving comfort. Overall, this design represents progress in the automotive industry, making daily travel easier and more carefree.

How Should the Driver Handle a Rear Tire Blowout?

Here are the steps to handle a tire blowout while driving: 1. Maintain straight-line driving. If the front tire bursts, the car body will suddenly tilt to one side, and the vehicle direction will deviate or sway. At this time, the driver should not panic but firmly hold the steering wheel with both hands to keep the car moving straight. 2. Adjust the car direction gently. When turning the steering wheel, the movements should be gentle, avoiding repeated sharp turns. 3. Slow down gradually. When decelerating, first release the throttle while keeping the gear engaged. When the car's posture is under control, downshift step by step and repeatedly apply light brake pressure to bring the car to a slow stop. 4. Turn on the warning lights. Once the situation stabilizes, activate the turn signals or parking warning lights and allow the car to come to a gentle stop.

Do You Need to Step on the Brake When Starting an Automatic Car?

When starting an automatic car in a stationary position, you do not need to step on the brake. However, if the car is about to move, you need to step on the brake. 1. Stationary Start In this state, the car is usually in the "P" gear, which provides braking force. Therefore, you don't need to step on the brake when starting the car. However, from a safety perspective, stepping on the brake while starting is a good habit. 2. Starting to Move When starting the car at a traffic light or preparing to move, you need to step on the brake. In this situation, the car requires power, and most automatic cars have a lock when shifting from "P" to "R" or "N" gear. You must step on the brake to successfully shift gears. Therefore, you need to step on the brake first when starting the car.

How to Deal with Paint Spots on a Car?

Methods for removing paint spots from a car are as follows: 1. Use banana oil for cleaning: Banana oil, also known as thinner. Banana oil can be used to dilute paint and has a good cleaning effect on paint spots. It is generally available at paint stores, but be aware of its flammable, explosive, toxic, and volatile properties. Banana oil can corrode the paint surface, so it must not be used on the paint surface, but it is safe to use on car glass. 2. Use gasoline for cleaning: Gasoline, a well-known cleaning agent, is essentially equivalent to banana oil in nature. It has a good cleaning effect and does not have the strong corrosive properties of banana oil. It can be applied by wiping with a damp towel. 3. Use essential balm for cleaning: Car owners can use essential balm to remove adhered paint. 4. Use fine sandpaper or a blade to remove: Fine sandpaper, blades, etc., can also remove paint spots with careful operation, but there is a risk of scratching the paint surface. If the scratches are minor, they can be repaired by waxing and polishing without affecting the appearance.

Should You Engage the Handbrake or Shift to P Gear First in an Automatic Transmission?

For automatic transmission vehicles, it is acceptable to either shift to P gear first or engage the handbrake first, as there is no strict sequence between the two actions. However, before shifting to P gear, it is crucial to ensure that the vehicle has come to a complete stop. Failing to do so may damage the automatic transmission, which is an important point to note. Automatic transmission vehicles are equipped with a P gear, which stands for Parking gear and is used when parking and turning off the engine. More details are as follows: 1. Before turning off the engine, you must shift to P gear; otherwise, the vehicle cannot be turned off normally. 2. After shifting to P gear, the locking mechanism inside the transmission can lock the transmission gears, effectively locking the wheels indirectly. Even if the handbrake is not engaged, the vehicle will not move after shifting to P gear, but this does not mean you can skip engaging the handbrake. 3. If the handbrake is not engaged, the P gear locking mechanism may bear excessive force, potentially damaging it. Therefore, after shifting to P gear, it is essential to firmly engage the handbrake.

What Causes Abnormal Car Starting Sounds?

Abnormal sounds during car startup may result from the following reasons: 1. Hydraulic lifters: Air entering the hydraulic lifters due to low oil pressure or wear in the lifter itself. 2. Valve clearance: Excessive valve clearance caused by wear in the valve rocker arm. 3. Dirty throttle body: Accumulation of sludge and carbon deposits leading to a dirty throttle body. 4. Carbon canister purge valve operation sound: This is a normal sound and the vehicle can continue to be used. If the sound is too loud, it's recommended to have it checked at a 4S shop. 5. Catalytic converter: A "clicking" sound within half a minute after a cold start, which usually disappears afterward. This is typically caused by the expansion of the catalytic converter when heated.

The serial number is not allowed to be altered privately, and any engine replacement must be reported and recorded promptly. 2. The vehicle identification number (VIN) is the frame number of the vehicle, composed of 17 letters or numbers. It is a unique number for the car, which can be used to identify the manufacturer, engine and chassis serial numbers, and other performance-related information. There are two formats for vehicle identification numbers: the first follows the LS3779 standard, while the second, mainly used in North America, is more stringent than the first.
