How to judge left and right distances for novice drivers?

Novice drivers can judge left and right distances by using the positions of the left and right wipers as reference points. When the protruding node of the left wiper aligns with an object on the ground, the left wheel will run over that object while moving. Similarly, when the line of sight intersects the right wiper and a target, the right wheel will run over that target. More details on judging distances are as follows: 1. Judging the position of the left wheel: It is necessary to know where the left wheel will run over to avoid the tire pressing on solid lines or dodging potholes and stones on the road. When the driver's line of sight aligns the protruding node of the left wiper with an object on the ground, the left wheel will run over that object while moving. 2. Judging the position of the right wheel: When the driver's line of sight intersects the right wiper and a target, the tire will run over that target. Driving 60 cm from the roadside on the right: When the right washer nozzle overlaps with the target on the roadside, the body of the car is still 60 cm away from the roadside. Parking on the right side: When the node of the right wiper aligns with the roadside, slightly pulling the steering wheel to the left can achieve the effect of parking 10 cm away from the roadside.

What Happens If Spark Plugs Are Never Replaced?

Effects of not replacing spark plugs: If spark plugs are damaged, it can directly cause issues such as leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most importantly, difficulty in ignition, affecting the normal operation of the vehicle. Severe erosion of spark plugs, including scarring at the top, damage, or melting and erosion of electrodes, indicates that the spark plugs are already damaged and should be replaced. Methods to determine if spark plugs are damaged: Remove the spark plugs and observe them to assess their condition based on the following appearance colors. Normal spark plugs have insulator skirts and electrodes that appear gray-white, gray-yellow, or light brown. A properly functioning spark plug has a reddish-brown insulator skirt, an electrode gap between 0.8-0.9mm, and no signs of electrode burn. If the spark plug is covered with oil or deposits but is not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged, with signs such as scarring, black streaks, cracks, or melted electrodes at the top, the cause of the damage should be identified. After troubleshooting, replace the spark plug with a new one. Additionally, if the spark plug appears black as if smoked, it indicates that the wrong heat range was selected or that the air-fuel mixture is too rich, with oil seeping up.

What is the fuel tank capacity of the JMC Transit in liters?

The 2021 JMC Transit comes in 12 models, all of which have a fuel tank capacity of 68 liters. All models are equipped with a 2.8-liter turbocharged engine, paired with a 5-speed manual transmission (MT), and feature a front-engine, rear-wheel-drive layout. Among vehicles in the same class, the 2021 Dragon W5 has a fuel tank capacity of 70 liters, while the 2020 Ruitu has an 80-liter fuel tank. If owners wish to check the remaining fuel level, they can observe the fuel gauge on the right side of the instrument panel, which is marked with E and F. When the needle is close to E, it indicates that the fuel is running low, and when it is near F, it means the fuel level is sufficient. Fuel tank maintenance includes the following: Drain any accumulated water and sediment from the fuel tank, and check for oil leaks at the fuel pipe joints and switches. For fuel tank caps equipped with air valves and vapor valves, also check if the vent holes are clear. The filter screen at the fuel filler inlet should remain intact to prevent impurities from entering the tank during refueling and clogging the fuel lines. The sealing gasket on the fuel filler cap should also be in good condition to prevent fuel from spilling out while driving.

How to Classify A, B, and C-Class Cars?

Distinguishing between A, B, and C-class cars primarily involves three key points, as detailed below: 1. A-Class Cars: Typically, these have a wheelbase ranging from approximately 2.0 meters to 2.45 meters and an engine displacement of about 1.3 to 1.6 liters. A-class cars are generally divided into A00, A0, and A levels. The A00 level refers to microcars, such as the Alto or Benben, which feature smaller displacements and are notably fuel-efficient, making them ideal for commuting. 2. B-Class Cars: These usually have a wheelbase of around 2.7 to 2.8 meters and an engine displacement of about 1.8 to 2.4 liters. Common models include the Volkswagen Passat, Toyota Camry, Honda Accord, and Nissan Teana. Luxury brand models like the Audi A4, BMW 3 Series, and Mercedes-Benz C-Class, which are relatively compact but have wheelbases generally exceeding 2.7 meters, are also categorized as mid-size cars. 3. C-Class Cars: Vehicles in this category have a wheelbase of approximately 2.8 to 3.0 meters and an engine displacement exceeding 2.4 liters. Representative large-sized cars include the Audi A6L, Mercedes-Benz E-Class, and Toyota Crown. Other examples are the BMW 5 Series and similar models.

Where is the trunk switch of Changan CS55PLUS?

Here are the methods to open the trunk of Changan CS55PLUS: 1. On the driver's door panel, press the trunk button to open it. 2. Alternatively, use the trunk button on the key, press and hold for 2-3 seconds to open. 3. If the smart key is not nearby and remote opening is not possible, press and hold the trunk button on the key for 2 seconds to open it. Additional Information: There are several ways to open a car trunk: 1. Mechanical key opening. Insert the key into the tailgate lock to open or close the tailgate, which is the most mechanical method. Nowadays, this method is almost obsolete. 2. Direct opening with remote key. Opening the car trunk with a remote key is the most direct and simplest method. It is quite straightforward—just press the trunk opening button on the remote key. 3. Pressing the unlock button directly. Some car models may not have a dedicated trunk opening button on the remote key. In such cases, pressing the unlock button will also unlock the tailgate. 4. Smart sensing key + tailgate switch. Another method involves car models equipped with a smart sensing key. As long as the remote key is within a certain range (usually about 1 meter), pressing the switch on the tailgate will directly open the trunk.

What does the teapot symbol on the car dashboard mean?

The teapot symbol displayed on the car dashboard is the engine oil pressure warning light, usually red with a droplet graphic at the spout. This indicator serves to monitor whether the oil pressure is normal. When starting the car, dashboard indicators briefly illuminate as the system performs a self-check. If no issues are detected, all indicators will turn off. Reasons for the oil pressure warning light activation: 1. Insufficient oil level reduces pump efficiency or causes air ingestion, leading to pressure drop; 2. Overheating engine thins the oil, increasing leakage through component gaps; 3. Clogged oil filter or suction screen restricts oil flow; 4. Using incorrect oil grade or viscosity results in excessive leakage during engine operation.
