■Vehicle customization
●When the “Auto Lock by Speed” and “Auto Lock by Shift from P” 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 door s locked, the “Auto Lock by Speed” would
not operate.
• If the vehicle is started with any door unlocked, the “Auto Lock by Speed” will operate.
●When the smart access system with push-b utton start is off, the “Select Doors to
Unlock” cannot be customized.
●When the doors remain closed after un locking the doors and the “Auto Relock
Timer” activates, the signals will be generated in accordance with the “Lock/
Unlock Feedback-Tone” and the “Lock/Unlock Feedback-Lights” 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 battery discharge, leave the engine running while customizing the
features.
CAUTION
■During customization
As the engine needs to be running during customization, ensure that the vehicle is
parked in a place with adequate ventilatio n. In a closed area such as a garage,
exhaust gases including harmful carbon mo noxide (CO) may collect and enter the
vehicle. This may lead to death or a serious health hazard.
NOTICE
■During customization
To prevent battery discharge, ensure that the engine is running while customizing
features.
