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.
