You may temporarily disable the passive door locking feature by pressing the door unlock switch for three seconds on an open door. Passive door locking will then remain disabled until a door lock switch is pressed or until the power mode transitions from the off power mode. You can select to not have the horn sound when the passive lock occurs. If you choose this setting, the doors will automatically lock eight seconds after you turn the ignition off, remove a keyless access transmitter from the interior of the vehicle, and close both doors. You can also select to have the horn sound once when the passive lock occurs. If you choose this setting, the doors will automatically lock and the horn will chirp eight seconds after you turn the ignition off, remove a keyless access transmitter from the interior of the vehicle, and close both doors. If you are parking in a quiet area and do not want the horn to sound when the doors lock, press the lock button on the keyless access transmitter immediately after removing it from the interior and closing the doors. This will lock the doors and cancel the passive locking for this ignition cycle. The DIC will display PASSIVE LOCKING OFF, SILENT PASSIVE LOCK, or HORN AT PASSIVE LOCK. Press the OPTIONS button to change the setting. Passive Unlocking This feature allows you to select which doors will automatically unlock when you approach and open the driver's door with your keyless access transmitter. You can choose to have the driver's door unlock or both doors unlock. See Door Locks on page 2-10 for more information. The DIC will display PASSIVE UNLK DRIVER or PASSIVE UNLK BOTH. Press the OPTIONS button to change this setting. Auto Unlock This feature automatically unlocks either the driver's door or both doors, depending on the setting, when the shift lever is moved to PARK (P). The DIC will display AUTO UNLOCK OFF, AUTO UNLOCK DRIVER, or AUTO UNLOCK BOTH. Press the OPTIONS button to change the setting. Park Assist This feature tilts the passenger's side mirror downward when the shifter is moved to REVERSE (R). This can help you to see the curb while backing up. If you adjust the mirror while in REVERSE (R), the new position will be saved as the park assist position. The DIC will display PARK ASSIST OFF or PARK ASSIST ON. 3-79
