8-2. Customization
■Vehicle customization
●When the speed linked door locking function and shift position linked door locking
function are both on, the door lock operates as follows.
• When shifting the shift lever to any position other than P, all the doors will be
locked.
• If the vehicle is started with all the d oors 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 access system with push-button start is off, the selecting door to
unlock cannot be customized.
●When the doors remain closed after unlocking the doors and the automatic door
lock function (time elapsed before the automatic door lock function is activated if a
door is not opened after being unlocked) ac tivates, the signals will be generated in
accordance with the operation signal (buzzers) and the operation signal (emer-
gency flashers) settings.
■When customizing using the Remote Touch
Stop the vehicle in a safe place, apply the parking brake, and shift the shift lever to P.
Also, to prevent 12-volt battery discharge, leave the hybrid system operating while
customizing the features.

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.
