When trouble arises
LS600hL_U(OM50E41U)
■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).
■When a tire is replaced with a spare tire (vehicles with a spare tire)
The spare tire is also equipped with a tire pressure warning valve and transmitter. The
tire pressure warning light will turn on if the tire inflation pressure of the spare tire is
low. If a tire goes flat, the tire pressure warning light will not turn off even though the
flat tire has been replaced with the spare tire.
■Conditions that the tire pressure warning system may not function properly
 P. 4 5 9
■If the tire pressure warning light freque ntly comes on after blinking for 1 minute
If the tire pressure warning light frequently comes on after blinking for 1 minute when
the power switch is turned to ON mode, have it checked by your Lexus dealer.
■Warning buzzer
In some cases, the buzzer may not be hear d due to ambient noise or sounds from the
audio system.

The needle of the engine
coolant temperature gauge ( P. 99) enters
the red zone or a loss of hybrid system power is experienced. (For
example, the vehicle speed does not increase.)
●“Hybrid System Overheat” is shown on the multi-information display.
●Steam comes out from under the hood.
■If the needle of the engine coolant temperature gauge enters the red
zone
Stop the vehicle in a safe place an d turn off the air conditioning sys-
tem, and then stop the hybrid system.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:

Start the hybrid system and turn the air conditioning system on to
check that the radiator cooling fan operates and to check for coolant
leaks from the radiator or hoses.

after a cold start. Confirm that the fan is operating by checking the fan sound
and air flow. If it is difficult to check these, turn the air conditioning system on
and off repeatedly.
