4-3. Do-it-yourself maintenance
RX350/270_EE
■The initialization operation
●Make sure to carry out initialization after adjusting the tire inflation pressure.
Also, make sure the tires are cold before carrying out initialization or tire infla-
tion pressure adjustment.
●If you have accidentally turned the “ENGINE START STOP” switch off during
initialization, it is not necessary to press the reset switch again as initialization
will restart automatically when the “ENGINE START STOP” 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 level when the tires are cold,
and conduct initialization again.
■Warning performance of the tire pressure warning system
The warning of the tire pressure warning system will change in accordance with
driving conditions. 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.
■When initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the following cases,
the settings have not been recorded and the system will not operate properly. If
repeated attempts to record tire inflation pressure settings are unsuccessful, have
the vehicle inspected by any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional.
●When operating the tire pressure warning reset switch, the tire pressure warn-
ing light does not blink 3 times.
●After carrying out the initialization procedure, the tire pressure warning light
blinks for 1 minute then stays on after driving for 10 minutes.

RX350/270_EE
●If tire chains are used
●Vehicles with a full-size spare tire: If the spare tire is in a location subject to poor
radio wave signal reception
●Vehicles with a full-size spare tire: If a large metallic object which can interfere
with signal reception is put in the luggage compartment
■If the tire pressure warning light frequently 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 any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional.
■Customization

(Customizable features →P. 6 2 2 )
CAUTION
■When the electric power steering system warning light comes on
The steering wheel may become extremely heavy.
If the steering wheel becomes heavier than usual when operating, hold firmly and
operate using more force than usual.
■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 a tire is flat, change
it with the spare tire and have the flat tire repaired by the nearest authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
●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.
