■Electronic key battery depletion
●The standard battery life is 1 to 2 years. (The card key battery life is about a year and
a half.)
●If the battery is low, an alarm will sound in the cabin when the hybrid system is
started or stopped. ( P. 154)
●The battery becomes depleted even if the electronic key is not used because the
key always receives radio waves. If the smart entry & start system or the wireless
remote control does not operate, or the detection area becomes smaller, the bat-
tery may be depleted. Replace the battery when necessary. ( P. 532)
●To avoid serious deterioration, do not leave the electronic key within 1 m (3 ft.) of
the following electrical appliances that produce a magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Recharging cellular phones or cordless phones
• Table lamps
• Induction cookers
■When the electronic key battery is fully depleted
 P. 532
■Customization
Settings (e. g. smart entry & start system) can be changed.

CAUTION
■Caution regarding interference with electronic devices
●People with implantable cardiac pacemakers, cardiac resynchronization therapy-
pacemakers or implantable cardioverter defibrillators should maintain a reason-
able distance between themselves and the smart entry & start system antennas.
( P. 152)
The radio waves may affect the operation of such devices. If necessary, the entry
function can be disabled. Ask any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional for details, such as the frequency of
radio waves and timing of the emitted radio waves. Then, consult your doctor to
see if you should disable the entry function.
●Users of any electrical medical device other than implantable cardiac pacemak-
ers, cardiac resynchronization therapy-pacemakers or implantable cardioverter
defibrillators 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 medical
devices.
Ask any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional for details on disabling the entry function.
■When using the smart entry & start system and operating the power windows or
moon roof
Operate the power window or moon roof after checking to make sure that there is
no possibility of any passenger having any of their body parts caught in the window
or moon roof. Also, do not allow children to operate the smart entry & start system.
It is possible for children and other pa ssengers to get caught in the power window
or moon roof.

■Precautions for the radar sensor and rear bumper
The rear bumper of vehicles with a rear pre-crash safety system is a functional part
that has radio wave permeability. Observe the following to ensure the system can
function effectively:
●Keep the rear bumper clean at all times.
Raindrops, ice or snow may dete riorate radar sensor performance.
●Do not subject the radar sensor or surrounding area to a strong impact.
If the sensor moves even slightly out of position, the system may malfunction. If the
sensor or surrounding area is subjected to a strong impact, always have the area
inspected and repaired by any authorized Lexus dealer or repairer, or another
duly qualified and equipped professional.
●Do not disassemble the radar sensor.
●Do not attach a towing hitch, bike holder, protective film or stickers to the center
portion of the rear bumper.
●Do not replace the rear bumper with non-genuine parts or modify it.
●For painting or repair of the rear bumper, consult with any authorized Lexus
dealer or repairer, or another duly qualified and equipped professional.

■If the tread on snow tires wears down below 4 mm (0.16 in.)
The effectiveness of the tires as snow tires is lost.
■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 vehicle, particularly around the wheels or
wheel housings.
• If the tire inflation pressure is extr emely higher than the specified level.
• If the spare tire is in a location subject to poor radio wave signal reception.*
• If a large metallic object which can interfere with signal reception is put in the
trunk.*
• 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.
*: Vehicles with a spare tire
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large display,
airport or other facility th at generates strong radio waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or other wire-
less communication device
If tire position information is not correctly displayed due to the radio wave condi-
tions, the display may be corrected by driving and changing the radio wave condi-
tions.
●When the vehicle is parked, the time taken for the warning to start or go off could
be extended.
●When tire inflation pressure declines rapidly for example when a tire has burst, the
warning may not function.

CAUTION
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as dangerous
handling characteristics, which may lead to an accident resulting in death or seri-
ous 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 than 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 kno w how they were used previously.
■When initializing the tire pressure warning system
Do not operate the tire pressure warning reset switch without first adjusting the tire
inflation pressure to the specified level. Otherwise, the tire pressure warning light
may not come on even if the tire inflation pressure is low, or it may come on when
the tire inflation pressure is actually normal.
■Caution regarding interference with electronic devices
●Users of any electrical medical device other than implantable cardiac pacemak-
ers, cardiac resynchronization therapy-pacemakers or implantable cardioverter
defibrillators 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 medical
devices.
●People with implantable cardiac pacemak-
ers, cardiac resynchronization therapy-
pacemakers 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.
