Tire pressure warning light
When the light comes on:
Low tire inflation pressure
such as
• Natural causes ( P. 8 2 7 )
• Flat tire ( P. 8 4 9 ) Adjust the tire inflation pres-
sure (including the spare tire)
to the specified level.
The light will turn off after a
few minutes. In case the light
does not turn off even if the
tire inflation pressure is
adjusted, have the system
checked by your Lexus dealer.
When the light comes on after
blinking for 1 minute:
Malfunction in the tire pres-
sure warning system.
( P. 8 2 9 ) Have the system checked by
your Lexus dealer.

Make sure to reset oil change system ■
When the tire pressure warning light comes on
Check the tire inflation pressure and adjust to the appropriate level. Pushing the tire
pressure warning reset switch does not turn off the tire pressure warning light. ■
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 or tire inflation pressure changes caused by temperature. In this case,
adjusting the tire inflation pressure will turn off the warning light (after a few min-
utes).

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.

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 “ENGINE START STOP” switch is turned to IGNITION ON mode, have
it checked by Lexus dealer.
CAUTION■
If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause loss of
vehicle control and result in death or serious injury. ●
Stop your vehicle in a safe place as soon as possible. Adjust the tire inflation pres-
sure immediately. ●
If the tire pressure warning light comes on even after tire inflation pressure adjust-
ment, it is probable that you have a flat tire. Check the tires. If the tire is flat,
change to the spare tire and have the flat tire repaired by the nearest Lexus
dealer. ●
Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you could
lose control of the steering wheel or the brakes.■
If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.

8305-2. Steps to take in an emergency
LX570_OM_OM60L21U_(U) CAUTION■
Maintenance of the tires
Each tire, including the spare (if provided ), should be checked monthly when cold
and inflated to the inflation pressure re commended by the vehicle manufacturer on
the vehicle placard or tire inflation pressu re label (tire and load information label).
(If your vehicle has tires of a different size than the size indicated on the vehicle
placard or tire inflation pressure label [t ire and load information label], you should
determine the proper tire inflation pressure for those tires.)
As an added safety feature, your vehicl e has been equipped with a tire pressure
monitoring system (TPMS-tire pressure wa rning system) that illuminates a low tire
pressure telltale (tire pressure warning light) when one or more of your tires is sig-
nificantly under-inflated. Accordingly, when the low tire pressure telltale (tire pres-
sure warning light) illuminates, you should stop and check your tires as soon as
possible, and inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS (tire pressure warning system) is not a substitute for
proper tire maintenance, and it is the driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not reached the level to trigger illumination of
the TPMS low tire pressure telltale (tire pressure warning light).

Resetting the tire pressure warning data
After adjusting the tire inflation pressu re, be sure to initialize the data. ( P. 76 4 )
If the message remains on, the system ma y have malfunctioned. Have the vehicle
inspected by your Lexus dealer as soon as possible. ■

In the following cases, the warning message may not be displayed even if vehicle-
to-vehicle distance decreases: ●
When your vehicle and the vehicle ahead are traveling at the same speed or the
vehicle ahead is traveling more quickly than your vehicle ●
When the vehicle ahead is traveling at a very low speed ●
Immediately after cruise control speed is set ●
At the instant the accelerator pedal is depressed
