What does the i warning light indicate?

i light is the brake system warning light. The introduction of the brake system and the conditions that the brake system must meet when the vehicle is in motion are as follows: Basic introduction to the brake system: A series of specialized devices that can forcibly reduce the vehicle's speed. The brake system mainly consists of four parts: the energy supply device, control device, transmission device, and brake. The main functions of the brake system are to decelerate or even stop a moving vehicle, maintain a stable speed for a vehicle going downhill, and keep a stationary vehicle from moving. When the vehicle is in motion, the brake system must meet the following conditions: Good braking performance; indicators for evaluating vehicle braking performance include: braking distance, braking deceleration, and braking time. Easy to operate with good directional stability during braking. During braking, the braking force should be reasonably distributed between the front and rear wheels, and the braking force on the left and right wheels should be basically equal to avoid deviation and skidding during braking. Good braking smoothness; braking should be gentle and stable, and release should be quick and thorough. Good heat dissipation and easy adjustment. This requires the brake shoe friction lining to have strong high-temperature resistance, quick recovery ability when wet, adjustable clearance after wear, and be dust-proof and oil-proof. When towing a trailer, the trailer should brake before the main vehicle and release braking after the main vehicle. If the trailer becomes detached, it should brake automatically.
When I first bought my car, I was also puzzled by the circled 'i' light. Later, I figured out it's the vehicle information system indicator. When it lights up, it means there's an important message stored in the central display waiting for you to check—it could be a reminder to replace the key battery due to low power, or a need to restart the vehicle if the smart key isn't detected. Some high-end models even use this light to indicate maintenance due dates, and occasionally it might flash if a door isn't properly closed. Last week, this light came on in my car, and a quick glance at the dashboard showed the trunk wasn't securely locked. After closing it properly, the light turned off. Most of the time, it's not a serious issue, but it's best to get into the habit of checking the central display for alerts.
