sure there is nobody around the power windows. You
must also make sure the heads, hands and other
parts of the bodies of all occupants are kept
completely inside the vehicle. If someone’s neck,
head or hands get caught in a closing window, it
could result in death or serious injury. When anyone
closes the power windows, make sure he or she
operates the windows safely.

use the power window switches without supervision.

switch to the “LOCK” position when you leave your
vehicle.
Never leave anyone (particularly a small child) alone
in your vehicle, especially with the ignition key still
inserted or with the ignition switch in a position other
than “LOCK”. Otherwise, he/she could use the power
window switches and get trapped in a window.
Unattended persons (particularly a small child) can
be involved in a serious accident.
