You should not continue driving when the coolant warning light comes on. The coolant warning indicates a lack of coolant, which can cause the engine to overheat. Continuing to drive under these conditions may damage the engine and reduce its lifespan. Another scenario is when the coolant warning light comes on right after starting the engine but disappears after the engine warms up. This happens because the coolant level is at the minimum threshold. It is recommended to check the coolant level in the reservoir every 20,000 kilometers and use a freeze point tester to verify if the coolant's freezing point is normal. If the freezing point is abnormal, the coolant should be replaced. Additionally, if visible flocculent particles are observed in the reservoir, it also indicates that the coolant needs to be replaced.

Is running a red light captured by photographing the vehicle or the person?

Running a red light will capture the license plate, but not the people inside the vehicle. The command center receives the images and compares the license plate information with the vehicle management office's data to retrieve comprehensive vehicle information, such as the owner, model, color, etc. This information is then entered by data processing personnel so that the offending vehicle owner can be notified. Criteria for determining a red light violation: The electronic eye captures three photos as evidence for determining a red light violation: the front wheels crossing the stop line, the rear wheels crossing the stop line, and the front wheels crossing the opposite stop line. Only when all three photos are present will it be considered a red light violation. Methods to avoid running a red light while driving: When there are arrow signal lights, follow the arrow lights; otherwise, follow the circular lights. When the red light is on, the front of the vehicle must not cross the stop line. When the yellow light is on, the front of the vehicle must not cross the stop line. When the green light starts flashing, if you are close and moving fast, you should proceed, as stopping might be difficult and you may cross the stop line. If you are far away, moving slowly, or the intersection is congested, you should stop. When driving in the city, develop the habit of looking for traffic lights whenever you see a crosswalk or stop line at an intersection.

What is the maximum wading depth of the Wuling Hongguang?

According to official specifications, the Wuling Hongguang has a maximum wading depth of 22 cm. Common tire specifications include 175/70R14 and 185/70R14, with body lengths of 4420mm and 4390mm. The vehicle features a front-engine, rear-wheel-drive layout paired with either a 6-speed or 5-speed manual transmission (MT). The maximum wading depth refers to the deepest water level a vehicle can safely pass through. Generally, sedans have a maximum wading depth not exceeding 30 cm, while SUVs can handle deeper water but should ideally not exceed 50 cm. Among common models, the GAC Trumpchi GS8 has a maximum wading depth of 30 cm, the Audi A4 32 cm, the Volkswagen Sagitar 30 cm, the Land Rover Range Rover 90 cm, the Jeep Compass 48 cm, and the Highlander 45 cm. SUVs clearly outperform sedans in wading capability. Generally, when driving through water, vehicle owners should take different precautions depending on the water depth and their car's specifications: When water reaches exhaust pipe level: This is relatively safe. Even if water enters the exhaust, the pressure inside can expel it. As long as the engine isn't turned off in the water, no backflow will occur. When water reaches door sill level: This becomes hazardous. Most electrical circuits, components and sensors are located at the vehicle's base, risking short circuits that could damage critical electronics and prevent normal startup. When water reaches air intake level: This is extremely dangerous. Driving through such conditions may cause immediate engine stall, resulting in permanent engine damage or complete failure.
