Two-year-old Mirancan crashed the car at around 10am on Sunday in the Lichtenrade area of Berlin.
He not only took the keys while his father was sleeping, but took a stool with him to the lift - so he could reach the buttons.
Unlocking his father’s Mercedes with the remote control key fob was no problem, and he soon started up the vehicle, which had been left in first gear.
Witnesses reported seeing the silver Mercedes estate shoot out from its parking space and hit a post.
A police spokesman told the BZ newspaper: “Only when witnesses looked into the car did they saw the little boy squatting on the driver’s seat.”
Nobody was injured in the crash.
