yellowblue Keys CAUTION: Leaving children in a vehicle with the ignition key is dangerous for many reasons. A child or others could be badly injured or even killed. They could operate power windows or other controls or even make the vehicle move. If they turned the ignition to RUN and moved the shift lever out of PARK (P), that would release the parking brake. Don't leave the keys in a vehicle with children. 2-2
