Methods to control speed when driving an automatic transmission car are: 1. Shift to a low gear and use the engine to control speed; 2. Gently press the accelerator; 3. Apply the brakes. The correct parking method for an automatic transmission car is to shift the gear to N after the car comes to a complete stop, engage the handbrake and turn off the engine, then shift the gear to P. The function of an automatic transmission is to use planetary gear mechanisms for shifting, which can automatically change gears based on the degree of accelerator pedal pressure and changes in vehicle speed. The driver only needs to operate the accelerator pedal to control the speed. The gears on an automatic transmission car are: P for Parking, also the starting gear; R for Reverse; N for Neutral; D for Drive, also known as the driving gear; S for Sport mode; L for Low gear.

The functions of the Auto Hold system are: 1. Replacing the driver's manual pulling of the parking brake lever with a button, making it simple and effortless, reducing the driver's operational intensity; 2. Achieving basic functions such as static parking, static release (off), and automatic release (off).

How to Check the Brand of a Tire?

The method to check the brand of a tire is to look at the sidewall rubber of the tire. The functions of a tire are: 1. To bear the weight of the entire vehicle; 2. To transmit traction and braking torque, improving the adhesion between the wheel and the ground; 3. To prevent severe vibrations and damage to vehicle components; 4. To adapt to the high-speed performance of the vehicle and reduce noise during driving. The maintenance methods for tires include: 1. Ensuring the tire pressure is within the correct range; 2. Regularly inspecting the appearance of the tires; 3. Keeping the tire surface clean; 4. Periodically checking the alignment and balance of the tires; 5. Controlling driving speed; 6. Ensuring the tires are used within their lifespan.

What is the normal range of tire pressure for an SUV?

The normal range of tire pressure for an SUV is approximately 2.2 to 2.5 bar. Tire pressure refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and engine damage can lead to the end of the car's life. Tire pressure is like the blood pressure of the car, and its level plays a crucial role in the car's performance and power. An SUV, or Sport Utility Vehicle, is different from an ORV (Off-Road Vehicle), which is designed for rough terrain. The full name of an SUV is Sport Utility Vehicle, meaning it is a suburban utility vehicle that combines the space functionality of a station wagon with the off-road capability of a pickup truck.

What are the reasons for a car alarm continuously sounding?

There are several reasons why a car alarm may continuously sound: 1. The vehicle's alarm system is overly sensitive; 2. A faulty door switch; 3. The anti-theft sensor's sensitivity is set too high. A car alarm system consists of one or more sensors connected to switches, pressure sensors, and motion detectors. The car alarm is a security device installed in vehicles that triggers when someone strikes, impacts, or moves the car. The sensors send signals to the controller indicating the intensity of the vibration. Based on the vibration intensity, the controller will emit a warning sound or activate a full alarm to deter thieves and alert the vehicle owner.

What are the main causes of engine shaking?

Engine shaking causes: 1. Ignition system issues: Faults in the vehicle's ignition system can cause shaking during idling. Typically, inspect the spark plugs and replace any faulty ones promptly. 2. Poor fuel quality: This is the most common issue during daily driving. Low-quality fuel can affect engine performance, causing shaking at idle. Always refuel at reputable gas stations using guaranteed-quality fuel. 3. Engine carbon buildup: Severe carbon deposits will naturally cause shaking and may also reduce power output. Timely carbon cleaning can resolve these issues. 4. Unstable oil pressure: Fluctuating oil pressure leads to poor fuel delivery, resulting in engine shaking. In such cases, promptly check and maintain oil pressure within normal operating range.
