CAUTION:
{
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, turn on the power sliding door
feature. Then if the door closes, it will close
under the control of the power door system.
If you want to close the power sliding door(s) when the
override switch(es) is turned off, pull the inside or outside
handle or the edge of the door. Move the door about
4 inches (10 cm) toward the closed position and release
it. The door will close completely and latch for you.
To close the power sliding door(s) when the override
switch(es) is turned on, pull the inside or outside handle
and slide the door all the way forward to the latched
position.
