{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. 2-20
