especially with the windows
closed in warm or hot weather.

children. When there are children
in the rear seat, use the window
lockout button to prevent
operation of the windows. See

restraints that fold down, always
return them to the full upright
position whenever an occupant is
seated in the seat.

top of the restraint is at the same
height as the top of the occupant's
head. This position reduces the
chance of a neck injury in a crash.
