■Vehicle customization
When the doors remain closed after unlocking the doors and the timer acti-
vated automatic door lock function activates, signals will be generated in
accordance with the operational signal (Emergency flashers) function set-
tings.
■When customizing using the navigation system
Stop the vehicle in a safe place, apply the parking brake, and shift the shift
lever to P (automatic transmission or continuously variable transmission) or N
(manual transmission). 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 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 battery discharge, ensure that the engine is running while cus-
tomizing features.
