Delayed Locking
When locking the doors with the
power lock switch and a door or the
liftgate 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
twice will override the delayed
locking feature and immediately lock
all the doors.
This feature will not operate if the
key is in the ignition.
You can program this feature using
the Driver Information Center (DIC).
See “Delay Door Lock” under
Vehicle Personalization (With DIC
Buttons) on page 5‑47.
Automatic Door Locks
The vehicle may have an automatic
lock/unlock feature. This feature
can be programmed using the
Driver Information Center (DIC).
See Vehicle Personalization (With
DIC Buttons) on page 5‑47 for more
information on DIC programming.
Lockout Protection
If the driver side power door lock
switch is pressed when the driver
door is open and the key is in the
ignition, all of the doors will lock and
then the driver door will unlock.
If the passenger side power door
lock switch is pressed when the
front passenger door is open and
the key is in the ignition, all of the
doors will lock and then the front
passenger door will unlock.
Safety Locks
The vehicle has rear door security
locks to prevent passengers from
opening the rear doors from the
inside.
Open the rear doors to access the
security locks on the inside edge of
each door.
To set the locks, insert a key into
the slot and turn it to the horizontal
position. The door can only be
opened from the outside with the
door unlocked. To return the door to
normal operation, turn the slot to the
vertical position.
