Locks all the doors
Unlocks the door
Turning the key rearward unlocks
the driver’s door. Turning the key

your Toyota dealer.
If communication between the electronic key and vehicle is
interrupted (P. 133) or the electronic key cannot be used
because the battery is depleted, the smart key system and

■Vehicle customization
●When the Speed linked door locking function and the Shift position linked
door locking function are both on, the door lock operates as follows.
• When shifting the shift position to any position other than P, all the doors
will be locked.
• If the vehicle is started with all the doors locked, the Speed linked door
locking function would not operate.
• If the vehicle is started with any door unlocked, the Speed linked door
locking function will operate.
●When the smart key system is off, Smart door unlocking cannot be custom-
ized.
●When the doors remain closed after unlocking the doors and the automatic
door lock function is activated, the signals will be generated in accordance
with the operation signal (buzzer) and the operation signal (emergency
flashers) settings.
■In the following situations, customize mode will automatically be turned
off.
●A warning message appears after the customize mode screen is displayed.
●The power switch is turned off.
●The vehicle begins to move while the customize mode screen is displayed.
WARNING
■Cautions during customization
As the hybrid system needs to be operating during customization, ensure
that the vehicle is parked in a place with adequate ventilation. In a closed
area such as a garage, exhaust gases including harmful carbon monoxide
(CO) may collect and enter the vehicle. This may lead to death or a serious
health hazard.
NOTICE
■During customization
To prevent 12-volt battery discharge, ensure that the hybrid system is oper-
ating while customizing features.
