When locking the doors with the power lock switch or the Remote Keyless Entry (RKE) transmitter and a door is open, the doors will lock five seconds after the last door is closed. You will hear three chimes to signal that the delayed locking feature is in use.

Pressing the power lock switch or the lock button on the RKE transmitter twice will override the delayed locking feature and immediately lock all the doors.

You can turn the delayed locking feature off or back on again by doing the following:

  1. Press and hold the power door lock switch in the lock position.
  2. Press unlock twice on the RKE transmitter.

This feature will not operate if the key is in the ignition.

You can also program this feature using the Driver Information Center (DIC). See "Door Lock Delay" under DIC Vehicle Customization .
