What does the 'service' light on the car dashboard mean?

The 'service' indicator on the car dashboard is a reminder for the driver that the vehicle requires maintenance. There are three types of maintenance services: 1. Regular maintenance: Every 5,000 kilometers, it's necessary to change the engine oil and oil filter, and inspect the air filter. Additionally, the brake discs and pads should be checked for replacement needs, as well as the brake fluid level and tire condition. 2. Periodic maintenance: Typically performed every 3 years or after 40,000 kilometers. Besides regular maintenance, this includes cleaning the fuel injectors, throttle body, and the vehicle's intake system. It also involves replacing transmission fluid, front and rear axle oil, coolant, brake fluid, etc. Tire wear should be inspected, and tires should be replaced if necessary. 3. Major maintenance: Usually occurs after the vehicle has traveled 100,000 kilometers. This involves a comprehensive inspection of the vehicle and replacement of parts as needed.

What is the function of fuel additive?

The function of fuel additive is to solve the carbon deposit problem in the fuel system of electronically controlled fuel injection vehicles, quickly restore the engine to its optimal working condition, and compensate for certain deficiencies in gasoline properties. It also imparts new superior characteristics to gasoline, such as improving atomization, reducing wear, protecting the engine, and lowering emissions. Fuel additive (also known as gasoline detergent or fuel additive) is a type of automotive chemical and a common name for the third generation of gasoline detergents. High-quality fuel additives contain purifying factors that can clean harmful substances like gum deposits in fuel and engine carbon deposits. Continuous use can eliminate carbon deposits in the fuel injectors, intake valves, and intake manifolds of the fuel system, restoring the vehicle's original power and maintaining optimal working conditions over the long term.

Where to Insert the USB Drive in the Enclave?

The USB port of the Enclave is located inside the center armrest. Disadvantages of the Enclave: The vehicle noise is somewhat noticeable during high-speed driving, the configuration is not very good, mainly the interior odor is quite noticeable, the chassis is not particularly comfortable, the internal storage space is somewhat insufficient, the loading capacity is average, and it cannot carry too many daily items. Advantages of the Enclave: The interior does not have many physical buttons, all are touch buttons, and the central control screen is not very large—larger screens in this price range would be more impressive. Not only is the fuel consumption low, but the power experience is also very smooth.
