■Repair and replacement
It is recommended that genuine Lexus parts be used for repairs to ensure perfor-
mance of each system. If non-Lexus parts are used in replacement or if a repair shop
other than a Lexus dealer performs repairs, confirm the warranty coverage.
■Resetting the message indicating maintenance is required (U.S.A. only)
After the required maintenance is perfor med according to the maintenance sched-
ule, please reset the message.
To reset the message, follow the procedure described below:
Switch the display to the trip meter “A” ( P. 101) when the hybrid system is operat-
ing.
Turn the power switch off.
While pressing the trip meter reset switch ( P. 101), turn the power switch to the
ON mode (do not start the hybrid system because otherwise the reset mode will
be canceled).
■Allow inspection and repairs to be performed by a Lexus dealer
●Lexus technicians are well-trained specialist s and are kept up to date with the latest
service information. They are well informed about the operations of all systems on
your vehicle.
●Keep a copy of the repair order. It proves that the maintenance that has been per-
formed is under warranty coverage. If any problem should arise while your vehicle
is under warranty, your Lexus dealer will promptly take care of it. The message shown in the illustration will
appear on the display.
Continue to press and hold the button until
