While the vehicle is moving, always

Before you close the moon roof,
always make sure there is nobody
around the moon roof. You must
also make sure nobody places his
or her head, hands and other parts
of the body in the roof opening. If
someone’s neck, head or hands get
caught in the closing roof, it could
result in a serious injury. When
anyone closes the moon roof, first
make sure it is safe to do so.
Never leave small children alone in
the vehicle, especially with the igni-
tion key still inserted. They could
use the moon roof switches and get
trapped in the roof opening. Unat-
tended children can be involved in
serious accidents.
Never sit on top of the vehicle
around the roof opening.
