What does it mean when the warning light comes on?

[VanNevaeh]

The reasons for the warning light coming on are: 1. Engine oil indicator light: If this light stays on, it indicates that the engine may have a fault; 2. Battery indicator light: This means there is an issue with the battery and it needs to be replaced; 3. Water temperature indicator light: This indicates that the coolant temperature is too high, and the vehicle should be stopped immediately until the temperature returns to normal and the light goes off; 4. Brake pad indicator light: If this light comes on, it means the brake pads are faulty or excessively worn. If any of these warning lights come on while driving, the owner should identify the problem and immediately go to an auto 4S shop for inspection and repair.
