Programmable Automatic Door
Locks
Programmable automatic power door locks are intended
to provide enhanced security and convenience by
automatically locking and unlocking doors. This features
lets you program your power door locks to one of
four different modes.
Customizing the Automatic Door Locks
Mode 1: All doors automatically lock when the
transaxle is shifted out of PARK (P). The doors will
remain locked unless manually unlocked or the
lock button is pressed. All doors will unlock when the
transaxle is shifted into PARK (P) and the key is turned
to OFF.
Mode 2: This mode is only available with the remote
keyless entry system (if equipped). All doors
automatically lock when the transaxle is shifted out of
PARK (P). Automatic driver’s door only unlock when the
transaxle is shifted into PARK (P) and the key is
turned to OFF.
Mode 3: All doors automatically lock when the transaxle
is shifted out of PARK (P). No automatic door unlock.
Mode 4: No automatic door lock or unlock.
Before your vehicle was shipped from the factory it was
programmed in Mode 1. To determine the current
mode of the vehicle or to change to a different mode,
do the following:
1. Ensure the shift lever is in PARK (P) and all doors
are fully closed throughout this procedure. Turn the
ignition to ON.
2. Press and hold LOCK on either power door lock
switch for 10 seconds. Release the switch when
you hear the chime.
3. Count the number of chimes you hear. The number
of chimes tells you which mode your vehicle is in.
You can change the mode by pressing and
holding LOCK on the power door lock switch (two
chimes for Mode 2, three chimes for Mode 3
and four chimes for Mode 4).
4. Repeat Step 2 until you hear the number of chimes
that matches the mode you want.
The mode you selected is now set.
