WARNING
■Caution regarding interference with electronic devices
●People with implantable cardiac pacemakers, cardiac resynchronization therapy- pacemakers or implantable cardioverter de fibrillators should maintain a reasonable distance between themselves and the smart entry & start system antennas. ( P. 153)
The radio waves may affect the operation of such devices. If necessary, the entry function can be disabled. Ask any authorized Lexus retailer or Lexus authorizedrepairer, or any reliable repairer 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 dis- able the entry function.
●Users of any electrical medical device other than implantable cardiac pacemakers,
cardiac resynchronization therapy-pacemakers or implantable cardioverter defi- brillators should consult the manufacturer of the device for information about itsoperation under the influence of radio waves.
Radio waves could have unexpected effects on the operation of such medical devices.
Ask any authorized Lexus retailer or Lexus au thorized repairer, or any reliable repairer
for details on disabling the entry function.

WARNING
■When the Emergency Call may not be made
●Any of the followings may occur. In such cases, report to the Public Safety Answering Point (PSAP) by other means such as nearby public phones.
• It may sometimes be difficult to connect to the Public Safety Answering Point (PSAP) even in the reception area of the cellular phone due to the reception level,or if the line is busy.
In such cases, you may not be able to connect to the Public Safety Answering Point (PSAP) and thus will not be able to make emergency calls and report to the emer- gency departments even though the system tries to connect to the Public Safety
Answering Point (PSAP). • When the vehicle is out of the cellular phone service area, the Emergency Callcannot be made.
• When any related equipment (such as th e “SOS” button panel, indicator lights, microphone, speaker, DCM, antenna, or any wires connecting the equipment.)has an abnormality, is damaged or brok en, the Emergency Call cannot be made.
• During the Emergency Call, the system makes repeated attempts to connect to the Public Safety Answering Point (PSAP). However, if it cannot connect to thePublic Safety Answering Point (PSAP) due to poor radio wave reception, the sys-
tem may not be able to connect to the cellular network and the call may finish with- out connecting. The red indicator light w ill blink for approximately 30 seconds to indicate this disconnection.
• This device may not function if a shock is applied to it.
●If the 12-volt battery’s voltage decreases or there is a disconnection, the system may
not be able to access the Public Safety Answering Point (PSAP).
■When replacing DCM to a new one
ERA-GLONASS have to be activated. Contact any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer.

4206-3. Do-it-yourself maintenance
GS450h_300h_OM_OM30F92E_(EE)
■When rotating the tires (vehicles with the tire pressure warning system featuring a tire inflation pressure display function)
Make sure that the power switch is off. If the tires are rotated while the power switch is in
ON mode, the tire position information will not be updated. If this accidentally occurs, either turn the power switch to off and then to ON mode, orinitialize the system after checking that the tire pressure is properly adjusted.
■Low profile tires (except 225/50R17 tires)
Generally, low profile tires will wear more rapidly and tire grip performance will be reduced on snowy and/or icy roads when comp ared to standard tires. Be sure to use
snow tires or tire chains on snowy and/or icy roads and drive carefully at a speed appro- priate for road and weather conditions. ( P. 336)
■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 (vehi- cles with the tire pressure warning system)
●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 wheel without the tire pressure warning valve and transmitter 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.

WARNING
■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 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 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 know how they were used previously.
●Vehicles with compact spare tire: Do not tow if your vehicle has a compact spare tire
installed.
●Vehicles with emergency tire puncture repair kit: Do not tow anything if a tire that has been repaired using the emergency tire punc ture repair kit is installed. The load on
the tire may cause unexpected damage to the tire.
■When initializing the tire pressure warning system (vehicles with the tire pressure warning system)
Do not initialize tire inflation pressure withou t first adjusting the tire inflation pressure to the specified level. Otherwise, the tire pre ssure 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 (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 cardioverter defi-
brillators 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 pacemakers, cardiac resynchronization therapy-pacemak-
ers or implantable cardioverter defibrillators should not come within 450 mm (17.7 in.) ofthe tire pressure warning system initiators.
The radio waves may affect the operation of such devices.
