collision with resulting death or serious in jury to you, your occupants or others.
■General precaution regarding children’s safety

Children may be able to start the vehicle or sh ift the vehicle into neutral. There is also a
danger that children may injure themselves by playing with the windows, the moon
roof, or other features of the vehicle. In addition, heat build-up or extremely cold tem-
peratures inside the vehicl e can be fatal to children.
