Vehicle specifications
■Vehicle customization
●If the smart key system is turned off, unlock door cannot be selected.
● If the doors are not opened after unlocking and are then automa tically re-
locked, a signal will be given if Operation signal (Emergency f lashers) or
Operation signal (Buzzer) are set to on.

customizing the features.
WARNING
■ During customization
As the engine needs to be running 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 seri ous health
hazard.
NOTICE
■ During customization
To prevent battery discharge, ensure that the engine is running while cus-
tomizing features.
