Smart Unlocks for Integrated Keyhead Transmitter
This feature helps to prevent you from locking yourself out of the vehicle
if your key is still in the ignition.
When you open one of the front doors and lock the vehicle with the
power door lock control, all the doors will lock then unlock if your key is
still in the ignition.
The vehicle can still be locked with the key in the ignition by using the
keyless entry keypad with the driver door closed, or by pressing the lock
button on the transmitter even if the doors are not closed.
If both front doors are closed, the vehicle can be locked by any method,
regardless of whether the key is in the ignition or not.
Smart Unlocks for Intelligent Access Keys (If Equipped)
This feature helps to prevent you from unintentionally locking your
intelligent access key inside your vehicle’s passenger compartment or
rear cargo area.
When you lock your vehicle using the driver or passenger power door
lock control (with the door open, vehicle in park and ignition off), after
you close the door the vehicle will search for an intelligent access key in
the passenger compartment. If an intelligent access key is found inside
the vehicle, all of the doors will immediately unlock and the horn will
chirp, indicating that the intelligent access key is inside.
