Delayed Locking
The delayed locking feature can be programmed to one
of the following modes:
ON: Lock your vehicle using the power door lock switch
or the remote keyless transmitter while any door is
opened, you will hear three chimes and the doors will
not lock. Five seconds after the last door is closed,
all doors will lock.
Once delayed locking is programmed to ON, you can do
the following:
Cancel the delayed locking by pressing unlock
using the power door lock switch or by fully inserting
the key in the ignition,
override the delayed locking feature by pressing
lock immediately using the power door lock
switch, or
let the delayed locking feature complete the locking
of the vehicle.
OFF: The doors will always lock immediately when you
lock the doors using the power door lock switch or
press LOCK on the remote keyless entry transmitter.
Before your vehicle was shipped from the factory, it was
programmed in ON. The mode to which the vehicle
was programmed may have been changed since it left
the factory. To determine the mode to which your
vehicle is programmed or to program your vehicle to a
different mode, do the following:
1. Follow the instructions for "Entering Programming
Mode" listed previously.
2. Press the MODE button until DELAYED LOCKING
appears on the DIC.
3. Press the SET button until the arrow is before ON
or OFF.
The mode you selected is now set. You can either exit
programming mode by following the instructions
later in this section or program the next feature available
on your vehicle.
