When trouble arises
LS600h/LS600hL_EE(OM50D61E)
 Front passenger detection sensor, seat belt reminder and warning buzzer
 If luggage is placed on the front passenger seat, the front passenger detec-
tion sensor 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.
 Electric power steering system warning light
When the 12-volt battery charge becomes insufficient or the voltage tempo-
rarily drops, the electric power steering system warning light may come on.
 If the malfunction indicator lamp comes on while driving
The malfunction indicator lamp will come on if the fuel tank becomes com-
pletely empty. If the fuel tank is empty, refuel the vehicle immediately. The
malfunction indicator 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 suf-
ficiently.
 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
inflation 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).
