sor may cause the warning light to flash and the warning buzzer to sound even if a
passenger is not sitting in the seat.
●If a cushion is placed on the seat, the sensor may not detect a passenger, and the
warning light may not operate properly.

drops, the electric power steering system warning light may come on and the warn-
ing buzzer may sound.

The malfunction indicator lamp will come on if the fuel tank becomes completely
empty. If the fuel tank is empty, refuel the vehicle immediately. The malfunction indi-
cator lamp will go off after several trips.
If the malfunction indicator lamp does not go off, contact any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional as soon as
possible.
■When the tire pressure warning light comes on
Carry out the following procedure after the tire temperature has lowered sufficiently.
●Check the tire inflation pressure and adjust it to the appropriate level.
●If the warning light does not go out after several minutes, check that the tire infla-
tion pressure is at the specified level and carry out initialization.
The warning light may come on again if the above operations are conducted without
first allowing the tire temperature to lower sufficiently.
■The tire pressure warning light may come on due to natural causes
The tire pressure warning light may come on due to natural causes such as natural
air leaks and tire inflation pressure changes caused by temperature. In this case,
adjusting the tire inflation pressure will turn off the warning light (after a few minutes).
