their seat belts or not wearing them properly
may be thrown out of the opening. Such an
opening also presents a potential for injury
for occupants wearing their seat belts
properly as entire body parts or portions of
them may protrude from the passenger
compartment.

sition of the tilt/sliding sunroof or open a side
window slightly.

sunroof using the SmartKey, see “Summer open-
ing feature” (
