Power Windows
The windows can be opened/closed by
operating the power window switches.
WA R N I N G
Make sure the opening is clear before
closing a window:
Closing a power window is dangerous. A
person's hands, head, or even neck could
be caught by the window and result in
serious injury or even death. This warning
applies especially to children.
Never allow children to play with power
window switches:
Power window switches that are not locked
with the power window lock switch would
allow children to operate power windows
unintentionally, which could result in
serious injury if a child's hands, head or
neck becomes caught by the window.
Make sure nothing bloc ks the w indow just
before it reaches the fully closed position or
while holding up the power window switch:
Blocking the power window just before it
reaches the fully closed position or while
holding up the power window switch is
dangerous.
In this case, the jam-safe function cannot
prevent the window from closing all the
way. If fingers are caught, serious injuries
could occur.
NOTE
When driving with only 1 of the rear
windows open, your ears might experience
a resonating sound. However, this does not
indicate a problem. The sound can be
reduced by slightly opening a front
window or by changing the size of the rear
window opening.
