■Situations in which the tire pressure warning system may not operate properly
●In the following cases, the tire pressure warning system may not operate properly.
• If non-genuine Lexus wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equipment) tire. • A tire has been replaced with a tire that is not of the specified size.• Tire chains etc. are equipped.
• An auxiliary-supported run-flat tire is equipped. • If a window tint that affects the radio wave signals is installed.• If there is a lot of snow or ice on the vehi cle, particularly around the wheels or wheel
housings. • If the tire inflation pressure is extr emely higher than the specified level. • 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 registered in the tire pressure warning computer.
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large display, air- port or other facility that generates st rong radio waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or other wireless communication deviceVehicles with the tire inflation pressure display function: If tire position information is
not correctly displayed due to the radio wave conditions, the display may be corrected by driving and changing the radio wave conditions.
●When the vehicle is parked, the time taken for the warning to start or go off could be
extended.
●When tire inflation pressure declines rapi dly for example when a tire has burst, the warning may not function.
■The initialization operation
●Make sure to carry out initialization af ter adjusting the tire inflation pressure.
Also, make sure the tires are cold before carry ing out initialization or tire inflation pres- sure adjustment.
●If you have accidentally turned the engine swit ch off during initialization, it is not neces-
sary to press the reset switch again as init ialization will restart automatically when the engine switch has been turned to IGNITION ON mode for the next time.
●If you accidentally press the reset switch when initialization is not necessary, adjust the
tire inflation pressure to the specified leve l when the tires are cold, and conduct initial- ization again.
■Warning performance of the tire pressure warning system
The warning of the tire pressure warning syst em will change in accordance with the con- ditions under which it was initialized. For this reason, the system may give a warning even if the tire pressure does not reach a low enough level, or if the pressure is higher than the
pressure that was adjusted to when the system was initialized.

WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents. Failure to do so may cause damage to parts of the drivetrain as well as dangerous han-
dling characteristics, which may lead to an acc ident resulting in death or serious injury.
●Do not mix tires of different makes, models or tread patterns. Also, do not mix tires of remarkably different treadwear.
●Do not use tire sizes other th an those recommended by Lexus.
●Do not mix differently constructed tires (radial, bias-belted or bias-ply tires).
●Do not mix summer, all season and snow tires.
●Do not use tires that have been used on another vehicle. Do not use tires if you do not know how they were used previously.
●Vehicles with a compact spare tire: Do not tow if your vehicle has a compact spare
tire installed.
●Vehicles with an emergency tire puncture repa ir kit: Do not tow anything if a tire that has been repaired using the emergency tire puncture repair kit is installed. The load
on the tire may cause unexpected damage to the tire.
■When initializing the tire pressure warning system
Do not operate the tire pressure warning re set switch without first adjusting the tire
inflation pressure to the specified level. Ot herwise, the tire pressure warning light may not come on even if the tire inflation pressu re is low, or it may come on when the tire inflation pressure is actually normal.
■Caution regarding interference with electronic devices (vehicles with the tire pres-sure warning system featuring a tire inflation pressure display function)
●Users of any electrical medical device other than implantable cardiac pacemakers,cardiac resynchronization therapy-pacemakers or implantable cardioverterdefibrillators should consult the manufacturer of the device for information about its
operation under the influence of radio waves. Radio waves could have unexpected effects on the operation of such medicaldevices.
●People with implantable cardiac pacemakers,cardiac resynchronization therapy-pacemak-ers or implantable cardioverter defibrillators
should not come within 450 mm (17.7 in.) of the tire pressure warning system initiators.The radio waves may affect the operation of
such devices.

When trouble arises
RC200t_RC F_EE(OM24728E)
Indicates that the tire inflation pressure is low
Check the tire inflation pressure, and adjust to the appropriate level.
Indicates a malfunction in th e tire pressure warning sys- tem
Stop the vehicle in a safe place and turn the engine switch off then on again.If the tire pressure warning indicator flashes for 1
minute then illuminates, th ere is a malfunction in the system. Have the vehicle inspected by any autho-rized Lexus dealer or repairer, or another duly qual-
ified and equipped professional.
Indicates that the tire position information cannot be rec- ognized Drive for a short while and check if the display
updates. If the radio wave conditions improve, the displaymay return to normal. If the tire pressure is still not
displayed after driving for several minutes, stop the vehicle in a safe place, turn the engine switch offthen on again, and start driving.
If the tire pressure is still not displayed even after repeating this process several times, have the vehi-cle inspected by any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
