### Automatic Door Locks

The automatic door lock function is controlled by the remote function actuator (RFA) module on the vehicles equipped with the keyless entry. The RFA module receives a signal from the park/neutral position switch signaling whether or not the gear selector is in PARK. The RFA module provides a signal to the MALL to lock the doors under the following conditions:

• | The left front door is closed.

• | The vehicle is in RUN.

• | The gear selector is shifted out of PARK.

If programmed to do so, the RFA module also unlocks the doors when the gear selector is put back in to PARK.

### Automatic Door Lock Programming

The automatic door lock function provides for the following four selectable settings:

• | Automatic door locks Mode 0 -- No automatic door lock or unlock.

• | Automatic door locks Mode 1 -- Automatically locks all doors when the transmission is shifted out of park. But doors do not unlock automatically.

• | Automatic door locks Mode 2 -- Automatically locks all doors when the transmission is shifted out of park and automatically unlocks the driver's door when shifted into park or for the Bonneville by moving the ignition key to the off position.

• | Automatic door locks Mode 3 -- Automatically locks all doors when the transmission is shifted out of park and automatically unlocks all doors when shifted into park or for the Bonneville by moving the ignition key to the off position.

Vehicle are delivered programmed in mode 3.

### Delayed Locking (Option)

This feature lets the driver delay the actual locking of the vehicle. When the power door lock switch is pressed with the key removed from the ignition and the driver's door open, a chime will sound three times to signal that the delayed locking system is active. When all the doors have been closed, the doors will lock automatically after five seconds. If any door is opened before this, the five-second timer will reset itself once all the doors have been closed again.

Pressing the door lock switch twice within two seconds will override this feature.

### Personalization Programming

The delayed locking feature can be turned on or off for each driver's remote keyless entry transmitter. Vehicles are delivered with each remote keyless entry transmitter defaulted with delayed locking off.
