What is the correct way to start an automatic transmission car?

The correct way to start an automatic transmission car is: First, fasten your seat belt after getting in the car, start the engine while pressing the brake, release the handbrake, shift into D gear while pressing the brake, and then release the brake to start moving. Starting an automatic transmission car is very simple, and pressing the brake is for safety considerations. An automatic transmission eliminates the need for the driver to manually shift gears, as the vehicle automatically selects the appropriate gear based on driving speed and traffic conditions. There are six gear positions on an automatic transmission car, from top to bottom: P, R, N, D, S, L. Driving an automatic transmission car using only the parking gear P, reverse gear R, neutral gear N, and drive gear D can fully meet the needs of general driving. If you encounter some special driving conditions, you will need to use other functional gears.

Why is the car hard to start?

Difficulty in starting the car may be due to battery issues, or an inaccurate air-fuel mixture ratio, which can occur in both open-loop and closed-loop control systems. It could also be caused by unstable voltage in the ignition system's power supply. In colder weather, cars are more susceptible to weather conditions, with one of the more noticeable effects being difficulty in starting, especially for vehicles with high mileage. The car's ignition system is designed for spark-ignition engines to operate normally. It supplies the spark plugs with high-voltage electricity, approximately 15,000V to 30,000V, in the correct firing order for each cylinder, ensuring a strong enough spark to ignite the combustible mixture.

How often should the coolant in Lavida be replaced?

Lavida's coolant should be replaced every 40,000 kilometers. Coolant is an indispensable part of a car's engine, circulating within the engine cooling system to remove excess heat generated during engine operation and dissipate it into the atmosphere, ensuring the engine operates at an optimal temperature. Lavida's onboard navigation system combines touchscreen and knob controls, featuring MP3 playback capability, along with USB, AUX, and SD card expansion slots, making it user-friendly and highly functional. The LCD screen adopts a foldable design. Lavida not only maintains the superior quality of German design but also incorporates aesthetic concepts reflecting traditional Chinese culture and cutting-edge design elements of the era.

Where are the VIN and engine number located?

The engine number is generally found on the outer surface of the engine block, on the vehicle's nameplate, or on the nameplate in the engine compartment. The simplest and most direct method is to check the vehicle's administrative green book or the vehicle registration certificate. The engine number is like a person's ID number, representing each vehicle and containing very important information about the vehicle. The VIN (Vehicle Identification Number) is stamped on the vehicle's frame. The exact location varies by manufacturer, so you can refer to your vehicle's manual. Engine model numbers are identification codes assigned by engine manufacturers in accordance with regulations, industry or company conventions, and the attributes of the engine. These codes represent the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine, such as fuel type, number of cylinders, displacement, and static braking power. Engines installed in passenger cars or multi-purpose vehicles are required to display the manufacturer, model, and production number. The VIN, commonly referred to as the chassis number, is a professional term for the vehicle identification code. It is a unique set of characters assigned by the manufacturer to identify a vehicle. The VIN consists of 17 alphanumeric characters, also known as the 17-digit identification code, chassis number, or 17-digit number. The combination of these characters ensures that no two vehicles of the same model will have the same number within 30 years, making it a unique identifier for the vehicle—often referred to as the 'vehicle's ID card.' Common locations for the VIN include the vehicle registration certificate and the lower left side of the front windshield. It's important to note that the engine number is not the same as the engine model. The engine model refers to the specifications and size of the engine within the manufacturer's lineup, and multiple engines can share the same model. The engine number, however, is the production number assigned to each individual engine, and no two engines will have the same number. Engine number composition: Prefix: Includes the product series code, generation symbol, and regional or company code. Manufacturers may choose the appropriate letters, but these must be approved and registered by the relevant standardization authority. Middle section: Consists of symbols for the number of cylinders, cylinder arrangement, stroke, and bore diameter. Suffix: Includes symbols for structural features and intended use. Tail: A distinguishing symbol. Manufacturers may use appropriate symbols to differentiate between improved or modified versions of the same series. The suffix and tail may be separated by a hyphen. The VIN consists of 17 characters divided into three parts. Part 1: WMI—World Manufacturer Identifier (positions 1–3); Part 2: VDS—Vehicle Descriptor Section (positions 4–9); Part 3: VIS—Vehicle Identifier Section (positions 10–17).

What is the appropriate tire pressure for car tires?

Car tires should have the following appropriate tire pressure: 1. The front tires should have a pressure of 2.2 to 2.3 bar when unloaded and 2.4 to 2.5 bar when fully loaded; 2. The rear tires should have a pressure of 2.4 to 2.5 bar when unloaded and 2.6 to 2.8 bar when fully loaded. The recommended tire pressure range may vary depending on the tire model, and the standard tire pressure for the vehicle is usually indicated by the manufacturer. Tire pressure refers to the air pressure inside the tire. In car maintenance, the engine is the heart of the car, and its failure 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.

Why can't the remote key lock the car door?

The reason why the remote key cannot lock the car door is that insufficient battery power in the remote key can lead to unstable circuit performance and a shortened wireless communication distance, resulting in the phenomenon of the car door not locking. This issue can be resolved by replacing the battery. Both the infrared remote sensing and short-range wireless radio frequency circuits of the remote key are prone to failure, and these two methods are susceptible to interference from high-power devices, which can cause the key light to flash but fail to lock the door. The remote key utilizes the wireless remote control function of the central locking system, allowing the door to be opened or locked from a distance without inserting the key into the lock. The principle involves the key emitting a weak radio wave, which is received by the car's antenna. The electronic control unit then identifies the signal code, and the system's actuator performs the action of opening or closing the lock.
