How to Use Lights When Driving on Sharp Curves?

Use high beams on sharp curves. According to relevant regulations: When a motor vehicle passes through a sharp curve, slope, arch bridge, crosswalk, or an intersection without traffic signal control at night, it should alternately use high and low beams to signal. When a motor vehicle approaches sections with limited visibility due to sharp curves, the top of slopes, or other safety concerns, or when overtaking or encountering emergencies, it should slow down and sound the horn to signal. Motor vehicles traveling in the same lane should maintain a safe distance from the vehicle ahead to allow for emergency braking. Overtaking is prohibited under the following circumstances: 1. The vehicle ahead is making a left turn, U-turn, or overtaking; 2. There is a possibility of encountering an oncoming vehicle; 3. The vehicle ahead is a police car, fire truck, ambulance, or engineering rescue vehicle performing emergency duties; 4. Passing through sections such as railway crossings, intersections, narrow bridges, curves, steep slopes, tunnels, crosswalks, or urban areas with heavy traffic where overtaking conditions are not met.

Under What Circumstances Is a U-Turn Not Allowed?

Under what circumstances is a U-turn not allowed? 1. Intersections with a no U-turn sign prohibit U-turns. If a U-turn is made at such an intersection and is captured by cameras or caught by traffic police, you will lose 3 points on your license. 2. Intersections with a no left turn sign also prohibit U-turns. If there is a 'no left turn' sign, it means U-turns are not allowed either, unless there is an additional explicit 'U-turn permitted' sign at the intersection, in which case you may perform a U-turn as indicated. 3. If the leftmost lane has a straight arrow, U-turns are not allowed. Traffic regulations state that U-turns are permitted at locations without no U-turn or no left turn signs or markings. However, you must check whether the center line on the ground in the U-turn lane is dashed. If it is solid, U-turns are not allowed; if it is dashed, U-turns are permitted. If it is a double yellow line, check whether your side is dashed. If it is dashed, U-turns are allowed; otherwise, they are not permitted.

How to Check Tire Pressure on the Buick Excelle?

The tire pressure of the Buick Excelle can be viewed on the small screen in the instrument cluster. Press the "MENU" button on the turn signal lever to switch the small screen to the "Vehicle Information Menu," where you can check the tire pressure monitoring and overspeed alarm pages. It should be noted that the base model does not have the tire pressure monitoring function. The tire pressure monitoring indicator is a yellow symbol, an irregular circle with no seal on top and four small spikes at the bottom, containing an exclamation mark inside. The illumination of the tire pressure monitoring indicator indicates abnormal tire pressure. Abnormal tire pressure is generally caused by one of the following three reasons: Abnormal tire pressure: The system usually alarms when the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator to illuminate. In this case, simply perform a tire pressure reset. Damaged tire pressure sensor: The tire pressure sensor, which is used to monitor tire pressure, is installed directly inside the tire and connected to the tire inflation port. If the sensor is damaged during driving, it can also cause the tire pressure warning light to illuminate. For sensor damage issues, only replacement with a new part is possible.

What is the maximum speed of the Highlander?

185 km/h is the maximum speed of the Highlander. The maximum speed refers to the highest driving speed that a car can achieve on a road with good horizontal conditions. It is the speed at which the driving resistance and driving force are balanced under windless conditions on a flat road surface. The Highlander is equipped with a 2.0T turbocharged engine with a maximum power of 162 kW and a maximum torque of 350 Nm. There are many factors that affect the maximum speed of a car, such as the power of the car's engine, the maximum torque of the engine, the speed at maximum torque, the transmission ratio of the drivetrain, and driving resistance. The maximum speed is obtained on a flat and windless road surface with zero acceleration, so the gradient resistance and acceleration resistance are zero. Therefore, the main resistance factors affecting the maximum speed are air resistance and rolling resistance. Automotive air resistance refers to the component of the air force acting on a car moving in a straight line in the direction of travel. Air resistance is directly proportional to the square of the speed. Therefore, high-speed driving has a very obvious impact on air resistance. At high speeds, the engine must use a considerable part of its power, or fuel energy, to overcome air resistance. Automotive rolling resistance refers to the resistance opposite to the direction of rolling when an inflated tire rolls in a straight line on an ideal road surface (usually a flat, dry, and hard road surface), with the central symmetrical plane of its outer edge aligned with the direction of wheel rolling.

Why is the fuel consumption of Geely Vision X6 so high?

The reasons for the high fuel consumption of Geely Vision X6 are as follows: 1. Poor driving skills: The same car driven by different people will have different fuel consumption. Vehicles driven aggressively for a long time will have significantly higher fuel consumption. Sudden braking or acceleration can increase fuel consumption by up to half compared to smooth driving, and the difference between city roads and highways is also very noticeable. 2. Low tire pressure: If the car is not inflated for a long time, it will increase the friction between the car and the ground. Greater friction requires more power to move the vehicle, thus increasing fuel consumption. The simplest way to check tire pressure, besides the onboard pressure monitoring system, is to feel the heaviness of the steering wheel. 3. Excessive engine carbon deposits: Carbon deposits caused by the chemical reactions of car fuel are almost unavoidable for all fuels. If not addressed for a long time, it will not only increase fuel consumption but also degrade engine performance, leading to various issues such as rough idling, poor acceleration, and excessive exhaust emissions. Adding a cleaning agent to the gasoline can help, but it is recommended to go to a 4S shop for a thorough cleaning. 4. Oxygen sensor failure: Once the oxygen sensor fails, the electronic fuel injection system and other computer systems will not receive the oxygen concentration information from the exhaust pipe, damaging the engine and significantly increasing fuel consumption. Aging of the oxygen sensor is inevitable, so it is recommended to check and replace it around 80,000 km. 5. Spark plug failure: If the spark plug fails to ignite the fuel effectively, it will lead to incomplete combustion, increasing unnecessary fuel consumption and causing adverse effects such as carbon deposits. The recommended solution is to go directly to a 4S shop for replacement.

What is the fuel consumption per 100 kilometers of the Geely Xingrui?

The actual fuel consumption of the Geely Xingrui is 8.4-8.7L/100km. The currently available Geely Xingrui models include the 2021 Luxury+ Edition, Space-Time Edition Star, Elite Edition, Space-Time Edition Moon, Premium Edition, Flagship Edition, and Luxury Edition, totaling 7 models. The official NEDC combined fuel consumption is 6.7L/100km. Among vehicles in the same class, the Jingyi S50 has an NEDC combined fuel consumption of 6.4L/100km, the Emgrand has 5.8-6.1L/100km, the Excelle has 4.7-5.0L/100km, the Corolla has 4.0-5.6L/100km, and the Excelle (Buick) has 5.3-5.9L/100km. The fuel consumption of a car is directly influenced by five major factors: driving habits, the car itself, road conditions, natural wind, and environmental temperature. Details are as follows: Driving habits: Aggressive driving behaviors such as sudden acceleration, frequent overtaking, and not easing off the throttle before stopping at red lights can increase fuel consumption. The car itself: Cars with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power output, requiring more gasoline for combustion. Heavier cars also have higher fuel consumption due to the greater driving torque needed. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance, leading to higher fuel consumption. Natural wind: Driving against the wind or on windy days increases the car's resistance, thereby increasing fuel consumption. Low environmental temperatures: When the engine block is cold, the injected gasoline does not atomize easily during cold starts, requiring more gasoline for combustion, which increases fuel consumption. Additionally, at low temperatures, the engine's computer may control the engine to run at higher RPMs to warm up, further increasing fuel consumption.
