HS250h_U_75050U
●If the smart access system with push-button start has not been used for 14 days
or longer, the doors cannot be unlocked at any doors except the driver’s door.
In this case, take hold of the driver’s door handle, or use the wireless remote
control or the mechanical key, to unlock the doors.
■Conditions affecting operation

lowing situations, the communication between the electronic key and the vehicle
may be affected, preventing the smart access system with push-button start, wire-
less remote control and immobilizer system from operating properly.

NOTICE
■When encountering flooded roads
Do not drive on a road that has flooded after heavy rain etc. Doing so may cause the
following serious damage to the vehicle:
●Engine stalling
●Short in electrical components
●Engine damage caused by water immersion
In the event that you drive on a flooded road and the vehicle is flooded, be sure to
have your Lexus dealer check the following:
●Brake function
●Changes in quantity and quality of engine oil, transaxle fluid for the hybrid system
etc.
●Lubricant condition for the bearings and suspension joints (where possible), and
the function of all joints, bearings, etc.
As flooding may damage components involved in P position control, the parking
lock may jam in the locked position.
■If the vehicle will not shift out of the P position
There is a possibility that the 12-volt battery is discharged. Check the 12-volt battery
in this situation.
