Remote Keyless Entry

The rear compartment lid opens under the following conditions:

    • The transaxle is in PARK
    • The ignition switch is in OFF

The courtesy lamps turn on for 15 seconds or until one of the following conditions occur:

    • A door is opened
    • The LOCK switch is pressed
    • The UNLOCK switch is pressed

Theft Deterrent

The horn and the park lamps activate if the door is opened without the theft deterrent system being deactivated.

The theft deterrent system is deactivated by using:

    • The front door key cylinders
    • The unlock button on the transmitter

Lock-Out Prevention

The power door locks are disable under the following conditions:

    • The key is in the ignition.
    • The driver's door is open.

You may override the lock-out prevention feature by pressing and holding the driver side power door lock switch for more than 3 seconds.

Auto Door Locks (ADL)

The auto door lock (ADL) feature is activated by the shift lever. The ADL is programmable by the owner for 4 different lock and unlock modes for each transmitter. The vehicle default is ADL Mode 3.

    • ADL Mode 0:
        No automatic door lock or unlock.
    • ADL Mode 1:
        All of the doors lock when the transaxle shifts out of PARK. None of the doors unlock automatically.
    • ADL Mode 2:
        All of the doors lock when the transaxle shifts out of PARK. The driver's door unlocks automatically when the transaxle shifts into PARK.
    • ADL Mode 3:
        All of the doors lock when the transaxle shifts out of PARK. All of the doors unlock automatically when the transaxle shifts into PARK.

In order to change the mode, refer to the following procedure:

  1. Turn the ignition switch to RUN
  2. Put the transaxle in PARK
  3. Close all of the doors
  4. Press and hold the door lock switch in the lock position
  5. While holding the power door lock switch, press the LOCK button on the transmitter.

After the initial activation of the transmitter LOCK button, each additional activation will increment the ADL mode by one, starting from the current ADL mode. If cycled beyond ADL Mode 3, the RFA module enters ADL Mode 0.

Delayed Locking

Delayed locking allows the driver to delay the locking of the vehicle after the power door lock switch is pressed. A chime sounds 3  times in order to let the driver know that the vehicle is in delayed locking mode. The following conditions must be present in order to activate the locking mode:

    • The lock switch is activated.
    • The driver door is open.
    • The key is out of the ignition switch.

After the doors have been closed for 5 seconds, the doors lock automatically. Opening any door before the 5 seconds elapse resets the timer. The timer restarts once all of the doors close again.

The delayed locking program may be programmed ON or OFF for each transmitter.

The following procedure turns off the delayed locking feature (if currently enabled):

  1. Hold the lock switch on
  2. Press the transmitter UNLOCK button:
  3.  - All of the doors unlock
     - The delayed locking remains enabled
  4. Press the transmitter UNLOCK again:
  5.  - All of the doors lock
     - The delayed locking is disabled

The following procedure turns on the delayed locking feature (if currently disabled):

  1. Hold the lock switch on
  2. Press the transmitter UNLOCK button:
  3.  - All of the doors lock
     - The delayed locking remains disabled
  4. Press the transmitter UNLOCK again:
  5.  - All of the doors unlock
     - The delayed locking is enabled

Personalization

Personalization allows the driver to customize the following features to each transmitter:

    • The auto door lock preference
    • The delayed locking preference
    • The perimeter lighting preference
    • The remote activation verification
    • The memory seat and mirror presets
    • The radio presets
    • The climate control presets

Perimeter Lighting

Perimeter lighting is a feature that allows the following components to illuminate when the vehicle is unlocked using the transmitter:

    • The headlamps
    • The park lamps
    • The backup lamps

Program the ON or the OFF function for each transmitter by holding the power door lock switch and pressing the panic button on the transmitter. The first press maintains the current status. The second press, while the power door lock switch is pressed, toggles the status.

The horn chirps feedback while in the programming mode. One chirp means that the perimeter is disabled. Two chirps means that the perimeter lighting is enabled. In order to enable perimeter lighting, the remote activation verification (RAV) mode must be set at 1, 3 or 5.

Post Crash Unlock

The keyless entry system provides the capability of unlocking all of the doors after a deployment of the vehicle airbags. After the airbags deploy, the body control module (SBM) sends a message to the remote function actuator (RFA) module. After 15 seconds, the RFA module commands the doors to unlock, unlocking all of the doors.
