GS350_250_OM_OM30E16E_(EE)
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. 1 2 9 )
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.

Operation of each component
GS350_250_OM_OM30E16E_(EE)
■Trunk light
The trunk light turns on when the trunk is opened.
■When closing the trunk
■Trunk easy closer (vehicles with power trunk lid)
In the event that the trunk lid is left slightly open, the trunk easy closer will automati-
cally close it to the fully closed position.
■Function to prevent the trunk being locked with the electronic key inside
●When all doors are being locked, closing the trunk lid with the electronic key left
inside the trunk will sound an alarm.
In this case, the trunk lid can be opened pressing the trunk release button on the
trunk lid.
●Even when the spare electronic key is put in the trunk with all the doors locked, the
key confinement prevention function can be activated so the trunk can be opened.
In order to prevent theft, take all electronic keys with you when leaving the vehicle.
●Even when the electronic key is put in the trunk with all the doors are locked, the
key may not be detected depending on the places and the surrounding radio wave
conditions. In this case, the key confinement prevention function cannot be acti-
vated, causing the doors to lock when the trunk is closed. Make sure to check
where the key is before closing the trunk.
●The key confinement prevention function cannot be activated if any one of the
doors is unlocked. In this case, open the trunk using the trunk opener.
Using the trunk grip, lower the trunk without
applying force to the side and push the trunk
down from the outside to close it.

GS350_250_OM_OM30E16E_(EE)
■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 compared to standard tires. Be sure to use
snow tires or tire chains on snowy and/or icy roads and drive carefully at a speed
appropriate for road and weather conditions. (→P. 3 5 6 )
■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
(vehicles 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.
• Lock nuts 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 extremely 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.
*
*
: Vehicles with a full-size spare tire only
●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 that generates strong radio waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or other wire- less communication device
Vehicles 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 cor-
rected 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 rapidly for example when a tire has burst, the
warning may not function.

CAUTION
■Caution regarding interference with electronic devices (vehicles with the tire
pressure warning system featuring a tire inflation pressure display 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.
NOTICE
■Repairing or replacing tires, wheels, tire pressure warning valves, transmitters
and tire valve caps (vehicles with the tire pressure warning system)
●When removing or fitting the wheels, tires or the tire pressure warning valves and
transmitters, contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional as the tire pressure warning valves and trans-
mitters may be damaged if not handled correctly.
●Make sure to install the tire valve caps. If the tire valve caps are not installed,
water could enter the tire pressure warning valves and the tire pressure warning
valves could be bound.
●When replacing tire valve caps, do not use tire valve caps other than those speci-
fied. The cap may become stuck.
■To avoid damage to the tire pressure warning valves and transmitters (vehicles
with the tire pressure warning system)
When a tire is repaired with liquid sealants, the tire pressure warning valve and
transmitter may not operate properly. If a liquid sealant is used, contact any autho-
rized Lexus dealer or repairer, or another duly qualified and equipped professional
or other qualified service shop as soon as possible. Make sure to replace the tire
pressure warning valve and transmitter when replacing the tire. (→P. 4 6 8 )
●People with implantable cardiac pacemak-
ers, cardiac resynchronization therapy-
pacemakers or implantable cardioverter
defibrillators should not come within
450mm (17.7 in.) of the tire pressure warn-
ing system initiators. The radio waves may
affect the operation of such devices.
