Door Locks
Programmable Automatic Power Door Locks is a
standard feature that is intended to provide enhanced
security and convenience by automatically locking and
unlocking doors. This feature provides four operating
modes. For your vehicle, you may select and program
one of the following four operating modes:
Mode 1: No automatic door lock or unlock.
Mode 2: Automatic all-door lock when the transaxle is
shifted out of PARK (P); no automatic door unlock.
Automatic door relock when any door is unlocked,
opened and then all doors are again closed while the
vehicle is not in PARK (P) or NEUTRAL (N) and the
driver's foot is on the brake pedal.
Mode 3: Automatic all-door lock when the transaxle is
shifted out of PARK (P).
Automatic all-door unlock when the transaxle is shifted
into PARK (P).
Automatic door relock when any door is unlocked,
opened and then all doors are again closed while the
vehicle is not in PARK (P) or NEUTRAL (N) and the
driver's foot is on the brake pedal.
Mode 4: Automatic all-door lock when the transaxle is
shifted out of PARK (P).
Automatic driver's door only unlock when the transaxle
is shifted into PARK (P).
Automatic door relock when any door is unlocked,
opened and then all doors are again closed while the

The operating mode of the Programmable Automatic
Power Door Locks will be changed when the driver
performs the following sequence with the engine not
running, the doors closed and the ignition key in RUN:
1. Apply your regular brakes.
2. Press and hold the power door lock switch. While
holding the door lock switch, cycle the transaxle out
of and back into PARK (P).
After an initial transaxle cycle, each additional cycle
will advance the operating mode by one, starting from
the current operating mode. During this procedure, the
automatic door lock and unlock functions will operate
as defined by each mode above, providing the driver
with feedback of the current operating mode. If
cycled beyond Mode 4, the vehicle will enter operating
Mode 1 . When the door lock switch is released, the
vehicle will remain in the most recent operating mode.
