NOTICE
■Notice on fuel quality
●Do not use improper fuels. If improper fuels are used, the engine will be dam-
aged.
●Do not use leaded gasoline.
Leaded gasoline will cause the three-way catalytic converter to lose its effective-
ness and the emission control system to function improperly.
●EU area: Bioethanol fuel sold under names such as “E50” or “E85” and fuel con-
taining a large amount of ethanol should not be used. The use of these fuels will
damage the vehicle’s fuel system. In case of any doubt, ask any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.
●Except EU area: Bioethanol fuel sold under names such as “E50” or “E85” and
fuel containing a large amount of ethanol should not be used. Your vehicle can
use gasoline mixed with 10% max ethanol. The use of fuel with more than 10%
ethanol content (E10) will damage the vehicle’s fuel system. You must ensure that
refueling is carried out only from a source where fuel specification and quality
can be guaranteed. In case of any doubt, ask any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.

■Vehicle customization
●When the entry function is off, the selecting doors 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) activates, 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 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 customizing
features.
