What is the reason for the vehicle displaying a brake failure warning and failing to start?

[FrankFitz]

It may be due to lack of fuel or a dead battery. If the shape of this warning light is the same as or similar to the handbrake light, and it remains on after releasing the handbrake, it indicates that the vehicle's brake pads have worn to the point of needing replacement. It is recommended to replace the brake pads at a 4S shop as soon as possible. If the warning light is shaped like a circle with a foot stepping on the brake, it means the vehicle is reminding you to press the brake before shifting from P to D gear. Below is additional information: Precautions: Check if the battery is dead. Prolonged use of electrical devices can drain the battery, leading to a failure to start. This situation often occurs in older cars that have been idle for a long time. Also, check if the gear is not properly set. Unlike manual transmission vehicles, automatic transmission vehicles cannot start if the gear is not in P or N but in R or D. Additionally, automatic transmissions cannot start if the steering wheel is locked.
