Two personalized exit positions can be set by first recalling the driver's position (by pressing 1 or 2), then positioning the seat in the desired exit position for that driver. Press and hold the button with the exit symbol for three seconds. A double chime will sound to let you know that the position has been stored. With the vehicle in PARK (P), the exit position for that driver can be recalled by pressing the exit button. The mirrors, power lumbar and recline positions will not be stored or recalled for the exit positions. If no exit position is stored, the default is all the way rearward. Further programming for automatic seat and mirror movement can be done through the Driver Information Center (DIC). You may choose to either select or not select the following: Automatic seat and mirror movement when the vehicle is unlocked with the remote keyless entry, automatic seat and mirror movement when a key is placed in the ignition, and automatic seat movement to the exit position when the vehicle is in PARK (P). 2-55
