Oldsmobile 2003 Silhouette Owner's Manual page 105

If your vehicle is facing c-- vnward 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.
