What does the blue P light on a Mercedes-Benz mean?

[AlexisLynn]

The blue P on a Mercedes-Benz stands for Parking-assistance, indicating the parking assist function. When it lights up, the reverse radar starts working. Generally, this function is automatically activated when the vehicle speed is below 35km/h. Notes about the P indicator are as follows: When the vehicle speed exceeds 35km/h: the blue P indicator will automatically disappear; When the speed is below 35km/h: if the automatic parking function is not turned off, the blue P will appear and the automatic parking space detection function will be activated; When a small triangular arrow appears next to the blue P: it means a suitable parking space has been detected. Simply shift into reverse, press the OK button on the steering wheel, and follow the prompts on the dashboard. Do not steer the wheel during the process—just shift gears as instructed.
