How Long Can You Drive with the Maintenance Light On?

You can drive approximately 500 kilometers with the maintenance light on. The purpose of the maintenance light is to remind the car owner to perform maintenance in a timely manner. Maintenance refers to the preventive work of regularly inspecting, cleaning, supplying, lubricating, adjusting, or replacing certain parts of the car, also known as car servicing. The benefits of maintenance include: 1. Ensuring the vehicle is in excellent performance condition; 2. Improving the vehicle's efficiency and reducing the wear of its parts and tires; 3. Enhancing driving safety; 4. Preventing potential hazards caused by vehicle issues; 5. Reducing noise and environmental pollution; 6. Keeping the vehicle's appearance clean and preventing damage.

Where are the clutch, accelerator, and brake pedals located in a sedan?

Manual transmission vehicles have three pedals arranged from left to right as follows: clutch pedal, brake pedal, and accelerator pedal. In manual transmission cars, the driver's left foot operates the clutch, while the right foot controls both the brake and accelerator. To start the vehicle, first, the engine should be ignited. Press the clutch pedal fully with your left foot, shift into first gear, and release the handbrake. Gradually release the clutch to the half-clutch position with your left foot. When the tachometer shows slight fluctuations or the vehicle begins to move, gently press the accelerator with your right foot while continuing to steadily release the clutch with your left foot. Once the vehicle starts moving, quickly lift your left foot off the clutch. During driving, do not rest your left foot on the brake pedal. In manual transmission vehicles, the left foot should only be used to press the clutch pedal when shifting gears. Under normal driving conditions, the left foot should not rest on any pedal. The brake and accelerator are both controlled by the right foot. There are two main reasons why the left foot should not rest on the pedals: 1. During long drives, both feet can become fatigued, leading to unintentional pressing. If the left foot is on the brake pedal, accidentally pressing it can easily cause an accident. 2. Most people are right-handed, meaning the right foot reacts faster. In an emergency, the right foot can quickly lift off the accelerator and press the brake. If the left foot is on the brake pedal, the right foot would be suspended, increasing the risk of pressing both pedals simultaneously, which is dangerous. Additional information about car brakes and accelerators: The brake is a mechanical device that slows down the vehicle, also known as a decelerator. The brake pedal is located below the steering wheel. Pressing it activates the brake linkage, which applies pressure to the brake pads on the brake drum, slowing or stopping the vehicle. The accelerator controls the fuel supply in an internal combustion engine. In cars, the accelerator is typically controlled by a pedal, also known as the throttle, which regulates the engine's fuel supply. When pressing the brake or accelerator, the body needs support to maintain balance. The right foot operates the pedals while the left foot stabilizes the body on the floor. If both feet are on the pedals, they are semi-suspended, lacking a stable base, which can lead to unstable pressing of the accelerator or brake. Tips for novice drivers: 1. Always use turn signals when changing lanes or turning: Lights and horns are the language of driving. Communicate your intentions early, especially as a beginner. Develop the habit of signaling well in advance and avoid changing lanes or turning immediately after signaling. 2. Follow proper procedures when overtaking: When overtaking, activate the left turn signal in advance and use high beams or the horn if necessary. On roads without a centerline or with only one lane, the leading vehicle should slow down and move to the right to allow overtaking if safe. The overtaking vehicle should pass from the left, maintain a safe distance, and signal before returning to the original lane. 3. Check surroundings before reversing: Before reversing, inspect the area around the vehicle. Do not rely solely on mirrors, parking sensors, or rearview cameras. If someone is guiding you, they should stand beside the vehicle, not behind it, to avoid being hit. 4. Slow down and observe at intersections: Intersections are complex with vehicles, pedestrians, and cyclists from all directions. Regardless of traffic lights, always look around and slow down to check for crossing traffic before proceeding. 5. Check for tailgaters before braking hard: During emergency braking, be aware of vehicles behind you. Maintain a safe distance from the car ahead to avoid rear-end collisions. 6. Keep a safe distance from the vehicle ahead: Road conditions can change suddenly. Control your speed and avoid speeding. Maintain enough distance to react to sudden stops or lane changes by other vehicles. 7. Slow down and check surroundings when turning: Reduce speed when turning and use mirrors to check for pedestrians or cyclists on the road. Yield to them to prevent collisions. 8. Prefer the middle lane when driving: On roads without a central divider, the middle lane provides more time to react to oncoming traffic. With dividers, it allows time to respond if someone or a vehicle suddenly emerges. At night, the middle lane reduces glare from opposing headlights. 9. Slow down and honk in poor visibility: In low-visibility conditions or weather, honk and reduce speed to ensure safe passage. 10. Slow down near parked large vehicles: Large vehicles can block your view. Be cautious of pedestrians or vehicles suddenly appearing from behind them. Slow down and proceed only when safe.

What is a Continuously Variable Transmission?

Continuously Variable Transmission (CVT) refers to a type of automatic transmission system in vehicles that can continuously obtain any transmission ratio within the gear range. A CVT is a type of automotive transmission, also known as a continuously variable transmission. Its working principle is as follows: in a CVT transmission system, traditional gears are replaced by a pair of pulleys and a steel belt. Each pulley consists of two conical discs forming a V-shaped structure. The engine shaft is connected to the smaller pulley, which drives the larger pulley via the steel belt. The functions of the transmission are: 1. Changing the transmission ratio to meet the traction requirements under different driving conditions; 2. Enabling reverse driving to meet the needs of backward vehicle movement; 3. Interrupting power transmission; 4. Engaging neutral gear.

Can a vehicle run without engine oil?

Without engine oil, a vehicle cannot operate. The method for adding engine oil is as follows: 1. Lift the vehicle, remove the protective plate, and place a container capable of holding about 10 liters beneath the oil drain plug. 2. Loosen the oil drain plug, use an air gun to blow into the oil filler port for two minutes, then tighten the drain plug after the oil has completely drained and wipe it with a tissue to check for leaks. 3. Reinstall the protective plate, lower the vehicle, and use a funnel to add engine oil through the filler port. The functions of engine oil are: 1. To separate the surfaces of relatively sliding parts, thereby reducing wear. 2. To carry heat back to the oil tank and then dissipate it into the air, assisting the radiator in cooling the engine. 3. To circulate carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank, flushing away contaminants generated on the working surfaces of the parts through the flow of the lubricating oil.

What are the causes of car shaking during acceleration?

Car shaking during acceleration can be caused by: 1. Loose connection between the transmission and chassis; 2. Uneven engagement of the clutch pressure plate and clutch friction disc; 3. Insufficient throttle input or rapid clutch release; 4. Malfunctions in the intake system, ignition system, or fuel system; 5. Clogged fuel injectors. The hazards of car shaking during acceleration include: 1. Damage to the spark plugs, resulting in poor ignition; 2. Increased carbon buildup in the fuel injectors; 3. Blockage of the throttle valve and intake manifold; 4. Accelerated aging of engine components; 5. Damage to the clutch pressure plate; 6. Increased engine load.

What Do the Numbers and Letters on Car Tires Mean?

Car tire numbers and letters indicate: 1. The first number represents the tire's section width, which is the width of the contact surface between the tire and the road during normal driving; 2. The second number represents the aspect ratio, and 'R' indicates that the tire is a radial tire with steel belts; 3. The following number indicates the rim diameter. The functions of tires are: 1. To transmit driving force, braking force, and steering force for vehicle operation; 2. To support the vehicle's load; 3. To reduce and absorb vibrations and impacts during driving, preventing severe vibrations from damaging car components. Tire maintenance methods include: 1. Regularly removing stones stuck in tire treads; 2. Minimizing exposure to direct sunlight; 3. Promptly checking tire pressure; 4. Paying attention to suspension maintenance; 5. Regularly inspecting front wheel alignment; 6. Being mindful of driving habits.
