What maintenance is needed for a new car at 25,000 kilometers?

Maintenance items required for a new car at 25,000 kilometers: 1. Air filter: After driving approximately 30,000 kilometers, the performance of the air filter can be significantly affected, becoming clogged with dust and oil; 2. Throttle body: A small portion of the combustion gases in the cylinders may pass through the intake valves and intake pipes, forming carbon deposits at the throttle body. Over time, this can create buildup, increasing the throttle's resistance and causing issues like unstable engine idling; 3. Cabin air filter: The cabin air filter contains activated carbon, which absorbs fine particles. The activated carbon gradually diminishes over time and with usage frequency; 4. Coolant: The coolant should be replaced every 20,000 kilometers or once a year to raise the boiling point, prevent scale and rust formation, and enhance cooling efficiency.

How to Use Light Signals?

The meanings of several commonly used light signals are as follows: 1. Flash headlights once: Nowadays, almost all roads are equipped with traffic lights to direct traffic. However, some intersections have longer red light durations, causing many drivers to lose focus while waiting. When the light turns green, they might not notice immediately. In such cases, flashing your headlights once can remind the driver in front to move. This method avoids creating noise. If the driver ahead still doesn’t respond, you can then use the horn. Additionally, when intending to overtake, flashing once can signal the driver ahead. 2. Flash headlights twice: One of the most annoying things when driving at night is encountering oncoming vehicles with high beams on. High beams make it difficult to see the road ahead, posing a significant safety hazard and increasing the risk of accidents. If you notice an oncoming car with high beams, flash your headlights twice to remind them to switch to low beams. 3. Flash headlights three times: While driving, you might notice other vehicles with potential safety issues, such as visibly low tire pressure or unclosed doors or trunks. In such cases, flashing your headlights three times can alert the other driver to the problem. This light signal could literally be lifesaving. If another driver uses this signal to alert you, be sure to pull over and check your vehicle. 4. Lane change signal: Changing lanes is often unavoidable while driving. If a neighboring car signals to merge into your lane ahead and you agree, flash your headlights once to indicate permission. 5. Intermittent brake light flashes: When driving, if the following vehicle is too close, sudden braking might cause the driver behind to react too late, leading to a rear-end collision. If you notice the following vehicle is too close while preparing to brake, you can lightly tap the brakes intermittently to remind the driver behind to maintain a safe distance.

What are the tips for car polishing?

Tips for car polishing: 1. Wash the entire vehicle with a paint cleaner that has strong decontamination power. When using the cleaner, avoid particles and dust causing new scratches during the grinding process; 2. Sand with water sandpaper: For defects such as coarse particles, fine sandpaper marks, or flow marks on the paint surface, use water sandpaper wrapped around a small rubber block with water to gently sand until smooth before polishing; 3. Coarse and fine grinding: Use a mechanical grinder with coarse grinding paste to coarsely grind the marks left by the water sandpaper, then add grinding paste for fine polishing; 4. Polishing: Use a mechanical polisher with a mirror-finish treatment agent to remove the swirl marks left by the coarse grinding paste, achieving a mirror-finish effect on the paint film; 5. Manual waxing: After grinding and polishing, clean off the grinding and polishing paste, immediately use a cotton cloth dipped in polishing wax to wipe the polished areas, then use a dry cotton cloth to remove any excess wax.

What is the actual fuel consumption of the KX1 automatic transmission?

The comprehensive fuel consumption of the KX1 is 5.7-5.8L/100km. There are currently 3 models of the 2021 KX1 available for sale. The CVT sunroof model and CVT Fun Edition have a comprehensive fuel consumption of 5.7L/100km. The manual Fun Edition has a comprehensive fuel consumption of 5.8L/100km. The above figures are the NEDC comprehensive fuel consumption, which is the data measured under the NEDC test procedure for combined driving conditions. The actual fuel consumption is higher than this value, ranging from 6.8-7.5L/100km. The level of a car's fuel consumption is directly related to five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Specific factors that can increase fuel consumption are as follows: Driving habits: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle before reaching traffic lights will increase fuel consumption. The car itself: Cars with larger displacement generally consume more fuel than those with smaller displacement because larger displacement usually means greater power output, requiring more gasoline for combustion. Heavier cars also have higher fuel consumption because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperature: When the engine block temperature is low during cold starts, the injected gasoline is harder to atomize, requiring more gasoline for combustion, which increases fuel consumption. Additionally, at low temperatures, the engine control unit will command higher idle speeds to warm up the engine, further increasing fuel consumption.
