When the water temperature gauge lights up, it indicates a malfunction in the engine's cooling system, which fails to ensure proper engine cooling. Here are the reasons for high car temperature: 1. Insufficient coolant: A decrease in coolant due to leakage can cause the water temperature to rise. In this case, check for any coolant leakage. If there is a leak, repair the leaking component as soon as possible. If there is no leakage, promptly add the appropriate coolant. 2. Problem with the cooling fan: A malfunctioning cooling fan can lead to increased water temperature. During high-speed operation, the heat generated cannot be effectively transferred to the antifreeze, affecting heat dissipation and causing the antifreeze temperature to rise, potentially leading to boiling over.

How to Control Speed When Turning?

When turning, the speed should not be too fast. You should slow down in advance before entering the curve and take the turn at a slow speed. Try to avoid using emergency braking and meeting other vehicles in the curve. The steering angle should be determined according to the actual situation, otherwise it is easy to lose control and cause an accident, and it is also not conducive to the driver observing the oncoming traffic in the curve. Extended information: 1. Turning at intersections: When turning left, the driver should signal in advance and keep as close to the center of the road as possible to facilitate vehicles behind and those turning right. When turning right, also signal first, turn slowly, and pay attention to the influence of the inner wheel difference to prevent the right rear wheel from going off the road and colliding with pedestrians or obstacles. 2. Turning on streets or at gate entrances: The driver should pay special attention to debris piled on the roadside, slow down and honk, and use turn signals or gestures to indicate the direction of travel. Follow the principle of 'slow down, look around, and then pass.' Pay close attention to the inside of the turn to guard against pedestrians, bicycles, or motorcycles that may be traveling alongside without clear direction. 3. Turning on narrow roads: The driver should honk and slow down before starting the turn, depending on the road conditions. When the view is obstructed in the curve, the vehicle should be driven to the right side of the road to avoid hindering the normal passage of other vehicles.

How much fuel can a Volkswagen Tharu's tank hold?

There are a total of 16 models of Volkswagen Tharu currently on sale. The fuel tank capacity of the two-wheel-drive version is 51 liters, while that of the four-wheel-drive version is 56.5 liters. These figures are officially released data. The recommended fuel grade for the Volkswagen Tharu is 95. The two-wheel-drive version has a fuel consumption of 5.9 to 6.5L per 100 kilometers, allowing a driving range of 785 to 864km on a full tank. The four-wheel-drive version has a fuel consumption of 7 to 7.2L per 100 kilometers, with a full-tank driving range of 784 to 807km. During daily driving, it is necessary to always pay attention to the remaining fuel level in the tank. This is usually observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments. Generally, when only 2 segments remain, it's time to refuel to avoid running out of fuel midway. During the actual refueling process, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity specified by the car manufacturer is measured from the bottom of the tank to the safety limit. There is additional space from the safety limit to the tank opening, which is designed to accommodate fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the calibrated tank capacity.

What does it mean when the EPC light in a vehicle is on?

The EPC indicator light can illuminate in two scenarios: during the power-on self-test and under other circumstances. The power-on self-test is an indicator that checks the status of all vehicle sensors before driving. Typically, if the vehicle is not started after powering on, the light will turn off by itself after about 3 seconds. If the EPC light stays on after starting the vehicle or illuminates under other conditions, the possible causes include faults in the engine intake system, throttle body, fuel system, engine, ECU control unit, or brake lights. Below is a detailed explanation of the reasons for the EPC light illuminating under other circumstances: Engine intake system fault: The EPC light will activate if the engine intake is obstructed or insufficient. Throttle body fault: Carbon buildup is a common issue with the throttle body. Additionally, dirt accumulation can affect intake and trigger the indicator light. Fuel system fault: This includes situations like substandard fuel, deteriorated fuel, or poor fuel atomization. Engine fault: Insufficient engine pressure or issues with components like the intake valve in the powertrain can also cause the EPC light to illuminate. ECU control unit fault: Examples include interference with the vehicle computer signals or false alarms from the vehicle computer. Brake light fault: This includes scenarios like non-functional brake lights, faulty brake switches, or brake circuit issues. Solutions for when the EPC light illuminates: Troubleshoot the intake system, use fuel with the appropriate octane rating, clean the throttle body, etc. Remove carbon buildup from relevant components. Re-flash the ECU with the correct data. If the EPC light comes on, the driver can first try turning off the engine and restarting it to see if the light remains off. If it does not illuminate again, there may be no issue, and the light might have been triggered by a temporary influence. If the EPC light stays on or frequently illuminates, it is advisable to drive to the nearest service center for professional diagnosis and repair to eliminate potential safety hazards. The full English name of EPC is Electronic-Power-Control, which translates to electronic power control. Most people refer to it as the engine electronic stability system. The EPC system primarily includes controllers and sensors related to the powertrain. When sensor data in the system is abnormal, the EPC system will take predefined actions on the powertrain. Common EPC indicator lights are usually displayed in two colors: yellow and red. A yellow EPC fault light indicates that the vehicle can still be driven, but it should be driven cautiously to a repair facility for inspection. A red EPC fault light signifies a more severe issue, and the vehicle should be pulled over immediately, with professional repair services contacted. Continuing to drive under such conditions could severely damage the vehicle's core components or compromise safety.

What transmission does the Beijing X3 use?

The transmission brand used in the Beijing X3 is Aisin. Established in 1969, Aisin is a world-renowned professional research and manufacturer of automotive automatic transmissions, holding the top global market share in the automotive automatic transmission sector. The Beijing X3 is equipped with a 6-speed manual transmission. A 6-speed manual transmission refers to a manual gearbox that includes 6 forward gears and 1 reverse gear. Manual transmission vehicles use a manual shift mechanical gearbox to regulate speed, meaning that shifting the gear lever changes the gear engagement inside the transmission, altering the gear ratio to achieve speed variation. The clutch must be depressed to move the gear lever. When using the Beijing X3's transmission daily, the following points should be noted: Do not delay transmission fluid changes for extended periods. Prolonged failure to change the transmission fluid can damage internal components such as bearings and the housing. Avoid coasting in neutral for long durations. While driving manual transmission vehicles, many experienced drivers may coast in neutral, but for automatic transmission models, this can cause the transmission to overheat and may result in a noticeable jolt when shifting back into Drive (D). Never shift into Drive (D) or Reverse (R) before the vehicle comes to a complete stop. Some drivers, aiming to demonstrate smooth operation, may shift into the opposite gear before the vehicle stops, which can severely damage the transmission gears and lead to issues like gear grinding over time. Avoid frequently climbing steep slopes in Drive (D). On steep inclines, automatic transmission vehicles may overheat due to high load or shift prematurely, causing a lack of power. In such cases, using manual mode to lock in lower gears or switching to sport mode can help protect the transmission. Do not tow over long distances. If an automatic transmission vehicle breaks down, it should be transported using a flatbed tow truck with the transmission in Neutral (N), rather than being towed directly with a tow rope or similar method.
