Power Door Locks — If Equipped
Vehicles equipped with power door locks can be locked
or unlocked from inside by either the use of the door lock
switches located on the front doors or by pressing the
LOCK or UNLOCK buttons on the Remote Keyless Entry
key fob.
As a safety feature the doors will not lock when using the
door lock switches during the following conditions:
1. The driver’s door is open while the key is in the
ignition.
2. The driver’s door is open while the headlight switch is
ON.
