If you have the dual sliding
doors, your vehicle has
these switches. The
left switch is for the driver's
side power sliding door
and the right switch is for
the passenger's side
sliding door. The power
sliding door and the power
sliding door override is
one switch.
Notice: If you leave the power sliding door on when
you go through an automatic car wash, the door may
accidentally open. Be sure the power sliding door is
turned off when going through a car wash.
The power sliding door override switch(es) will also stop
the door(s) immediately, while the door(s) is opening
or closing, when the override switch(es) is turned on.
The power sliding door(s) will only open if the transaxle
is in PARK (P). The transaxle does not have to be in
PARK (P) to close the door(s).
This switch is in front of the
driver's or the passenger's
side sliding door.
