It indicates slow traffic. Red represents congestion, yellow indicates slow traffic, and green signifies smooth flow. When using navigation, it informs drivers about real-time traffic conditions (congested, slow-moving, or unimpeded). This feature allows for advance knowledge of road conditions ahead, helping to avoid unexpected traffic accidents causing congestion, roads under construction that cannot be passed, or local traffic restrictions. Below is relevant content introduction: 1. Car navigation system: The car navigation system has GPS global satellite positioning functionality, allowing drivers to know their exact location anytime while driving. Some car navigation systems also integrate office and entertainment features for easy driving and efficient travel. 2. The car GPS navigation system consists of two parts: one part includes the GPS receiver and display device installed in the car; the other part is the computer control center, with both parts connected via positioning satellites.

Which is Suitable, 12V or 24V Car Battery Charger?

A 12V 24AH car battery charger using a 1.5A current can fully charge the battery within 16 hours. Common knowledge about battery charging and lifespan: The smaller the charging current (trickle charging), the longer the battery's lifespan. This is because a larger charging current leads to more intense chemical reactions inside the battery, which directly affects its lifespan. CCA parameter of the battery: There is a CCA parameter in the performance specifications of a car battery, which stands for the maximum discharge current value of the battery. When charging the battery, the charging current must never exceed the CCA current value. Otherwise, forced charging is no different from destroying the battery.

Is a Tire Temperature of 40 Degrees Normal?

Tire temperature of 40 degrees is normal. Tire maintenance tips: 1. Normal temperature: The normal operating temperature of dry tires ranges between 90 to 110 degrees Celsius. When the temperature exceeds 100 degrees, it's necessary to check the tires. 2. Normal tire pressure: Tire temperature varies depending on driving conditions and weather. If the tire pressure can be maintained between 2.4-2.6, it is considered normal. 3. Summer driving tips: Due to temperature effects, the gas inside the tires will automatically expand, causing tire pressure to rise from 2.3 kg to over 3 kg. To ensure proper tire pressure, it is recommended to fill tires with nitrogen in summer, and the filling pressure should be reduced by 10%.
