This is the Shandong Weili brand. Below is relevant information about car navigation systems: 1. Concept: A car navigation system is a driving assistance device that can help users accurately locate their current position, calculate the route based on a set destination, and guide users to their destination through both map display and voice prompts. 2. Operating Principle: GPS consists of three main parts: space satellites, ground monitoring, and user receivers. In space, 24 satellites form a distribution network, distributed across 6 quasi-synchronous orbits around the Earth, each orbit 20,000 kilometers above the ground with an inclination angle of 55°, with 4 satellites in each orbit. GPS satellites orbit the Earth every 12 hours, enabling any location on Earth to simultaneously receive signals from 7 to 9 satellites.

How to use the warm air in Geely Vision X3?

The method to use the warm air in Geely Vision X3 is: 1. Start the car; 2. Turn off the AC; 3. Wait for the water temperature to rise to normal temperature; 4. Turn the knob to the red zone to activate the warm air mode. The warm air utilizes the car's internal heat circulation and does not require the AC compressor to be turned on. Adjusting the air conditioning controls is sufficient to activate the warm air. When the car is started, the engine begins to warm up. Once the engine temperature gauge reaches the middle position, first turn on the warm air, set the air circulation to external to expel the cold air inside the car, and then switch the air circulation to internal. When there is a significant temperature difference between the inside and outside of the car, the front windshield is prone to fogging. In this case, adjust the warm air outlet direction to the setting that blows air onto the front windshield.

Can You Drive with Low Engine Coolant?

Low engine coolant in a car depends on the situation: 1. If it is below the minimum level but there is still some remaining in the reservoir, you can still drive; 2. If it is so low that the reservoir is nearly empty, you should not drive. Continuing to drive in this condition will cause the engine temperature to rise rapidly, and without the cooling effect of the coolant, it can lead to engine damage. The primary function of engine coolant is to maintain the operating engine within a normal temperature range, cooling it down when it gets too hot. Additionally, engine coolant also has anti-freeze, anti-corrosion, and anti-scale properties. Regularly check the car's cooling system and the remaining engine coolant level. If you find the engine coolant is insufficient, replenish it promptly.

The functions of the car air conditioning system include: 1. Achieving a cooling effect through the continuous circulation of refrigerant; 2. Utilizing engine coolant, waste heat, or heat generated by a burner as a heating source, which is then distributed by the blower to warm the air inside or outside the car, raising the temperature at the air outlets for heating purposes; 3. Drawing in fresh external air for ventilation and air exchange, which also helps prevent windshield fogging; 4. Removing dust, odors, smoke, and toxic gases from the car's interior to freshen the air, as well as humidifying the air to increase its relative humidity.
