LX570_OM_OM60L21U_(U) ■
When a tire is replaced with a spare tire
The spare tire is also equipped with the 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, even though the flat tire is replaced with the spare tire,
the tire pressure warning light does not turn off. Replace the spare tire with the
repaired tire and adjust the proper tire inflation pressure. The tire pressure warning
light will turn off after a few minutes. ■
If the tire pressure warning system is inoperative
The tire pressure warning system will be come inoperative in the following condi-
tions: (When the condition becomes norm al, the system will work properly.)●
If tires not equipped with tire pressure warning valves and transmitters are used.●
If the ID code on the tire pressure warning valves and transmitters is not regis-
tered in the tire pressure warning computer. ●
If the tire inflation pressure is 73 psi (500 kPa, 5.1 kgf/cm 2
or bar) or higher.
The tire pressure warning system may be disabled in the following conditions:
(When the condition becomes normal, the system will work properly.) ●
If electronic devices or facilities using similar radio wave frequencies are nearby. ●
If a radio set at similar frequencies is in use in the vehicle. ●
If a window tint that affects the radio wave signals is installed. ●
If there is a lot of snow or ice on the vehicle, in particular around the wheels or
wheel housings. ●
If non-genuine Lexus wheels are used. (Even if you use Lexus wheels, the tire
pressure warning system may not work properly with some types of tires.) ●
If tire chains are used. ●
If the spare tire is in a location subj ect to poor radio wave signal reception.●
If a large metallic object which can interfere with signal reception is put in the
luggage compartment.

Correction procedures
Stop the vehicle in a safe place and turn off the air conditioning
system, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled down
sufficiently, inspect the hoses and
radiator core (radiator) for any
leaks.
Radiator
Cooling fans If a large amount of coolant leaks,
immediately contact your Lexus
dealer.The following may indicate that your vehicle is overheating.
● The needle of the engine coolant temperature gauge (  P. 1 9 0 )
enters the red zone or a loss of engine power is experienced.
(For example, the vehicle speed does not increase.)
● Steam is coming from under the hood. STEP 1

LX570_OM_OM60L21U_(U) The coolant level is satisfactory if it
is between the “F” and “L” lines on
the reservoir.
Reservoir
“F”
“L”
Radiator cap
Add coolant if necessary.
(  P. 74 8 ) Water can be used in an emer-
gency if coolant is unavailable.
Start the engine and turn the air conditioning system on to check
that the radiator cooling fans op erate and to check for coolant
leaks from the radiator or hoses. The fans operate when the air conditio ning system is turned on immedi-
ately after a cold start. Confirm that the fans are operating by checking
the fan sound and air flow. If it is diff icult to check these, turn the air con-
ditioning system on and off repeatedly. (The fans may not operate in
freezing temperatures.)
If the fans are not operating:
Stop the engine immediately and contact your Lexus dealer.
If the fans are operating:
Have the vehicle inspected at the nearest Lexus dealer. STEP 4
