{ CAUTION:
Leaving children unattended in a vehicle is
dangerous, but it is even more dangerous if
the keyless access transmitter is also left in
the vehicle. A child or others could be badly
injured or even killed.
They could operate the power windows or
other controls or even make the vehicle move.
Do not leave the keyless access transmitter in
a vehicle with children.
