Sliding Door Lock
If your vehicle is facing downward on a steep
grade (15 percent or more), the door may not
stay open and could slam shut, possibly
injuring someone. To make sure the door
does not slam shut be sure to hold
it
open
until everyone is clear of the door,'and only
then allow it to slowly close.
