Automatic Door Lock The doors will automatically lock when the shift lever is moved out of PARK (P). The automatic door locking feature cannot be disabled. Lockout Protection To protect you from locking your key in the vehicle, this feature stops the power door locks from locking while the key is in the ignition and a door is open. If a power lock switch is pressed while a door is open and the key is in the ignition, both doors will lock and then the driver's door will unlock. A chime will sound continuously until both doors are closed. Programmable Automatic Door Unlock Your vehicle is programmed so that when the shift lever is moved into PARK (P) all doors will unlock. With the vehicle stopped and the engine running, door unlocking can be programmed through prompts displayed on the Driver Information Center (DIC). These prompts allow the driver to choose various unlock settings. For programming information, see DIC Vehicle Customization on page 203. 100
