What do you mean the car warning light is on?

When the car alarm light is on, it means that there is something wrong with one of the car systems. For example, when the oil pressure warning light is on, it means that the oil pressure or liquid level is too low; The water temperature indicator is on, indicating that the coolant temperature is too high or the liquid level is too low; The battery light is on, indicating that the battery voltage is low, and the engine generates insufficient or no power; When the engine fault light is on, it may be a mechanical fault or a circuit fault, which requires immediate measures. Brake system fault light: when the parking brake is pulled up, this light is yellow; If the light lights up in red while driving, it means that the brake fluid level in the reservoir is too low or the brake device is out of order. Check it as soon as possible. Low oil pressure indicator: If this indicator is on, it is likely that the oil pressure is too low to continue driving. Please turn off the engine and check the oil level. If the oil level is normal, but the indicator light is still on or flashing, do not start the engine rashly, otherwise it will damage the engine. Brake system fault indicator light: When this light is on, it is likely that the brake system is faulty and the brake system liquid level is too low. At this time, you should drive at a low speed, brake ahead of time and increase the pedal strength.
