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. This switch is in front of the driver's or the passenger's side sliding door. Pressing the part of the switch(es) with the don't symbol turns the power to the sliding door(s) off. When the power sliding door(s) is off, you will not be able to open the door(s) by using the power sliding door switch(es) located on the overhead console switchbank, using the switch in front of the driver's or the passenger's side sliding door, or using the remote keyless entry transmitter. 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). If the power sliding door(s) is open or in the process of closing when you shift out of PARK (P), a buzzer will sound. This is a warning that the sliding door(s) is not completely closed. If the power to the sliding door(s) is turned off, the buzzer will not sound indicating the door(s) is not completely closed. Notice: When your vehicle goes through an automatic car wash, be sure the power sliding door is turned off. If it isn't, the power sliding door may open accidentally. 2-16
