WARNING
■Caution regarding interference with electronic devices
●People with implantable cardiac pace-makers, cardiac resynchronization therapy-pacemakers or implantable
cardioverter defibrillators should maintain a reasonable distance between themselves and the smart
entry & start system antennas. ( P.122) The radio waves may affect the opera-
tion of such devices. If necessary, the entry function can be disabled. Ask any authorized Lexus retailer or Lexus
authorized repairer, or any reliable repairer for details, such as the fre-quency 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 pace- makers, cardiac resynchronization therapy-pacemakers or implantable
cardioverter defibrillators should con- sult 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 medi-
cal devices.
Ask any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer for details on disabling the entry
function.

object by the roadside at the entrance of a curve
• When driving on a narrow path sur- rounded by a structure, such as in a tun-nel or on an iron bridge
• When there is a metal object (manhole cover, steel plate, etc.), steps, or a protru-sion on the road surface or roadside
• When a crossing pedestrian approaches
very close to the vehicle*2
• When passing through a place with a low structure above the road (low ceiling,
traffic sign, etc.)
• When passing under an object (billboard,
etc.) at the top of an uphill road
• When rapidly closing on an electric toll gate barrier, parking area barrier, or other barrier that opens and closes
• When using an automatic car wash • When driving through or under objects that may contact the vehicle, such as thick
grass, tree branches, or a banner

dust, etc. from a vehicle ahead • When driving through steam or smoke• When there are patterns or paint on the
road or a wall that may be mistaken for a
vehicle or pedestrian*2
• When driving near an object that reflects radio waves, such as a large truck or guardrail
• When driving near a TV tower, broad- casting station, electric power plant, or other location where strong radio waves
or electrical noise may be present*2: Depending on the region in which the
vehicle was sold, the pedestrian detec-
tion function may not be available.
■Situations in which the system may not operate properly
●In some situations such as the following, a vehicle may not be detected by the radar

5-6. Using the other interior features
enabled.
 If the green indicator light flashes, an
emergency call is being made
(either automatically or manually).
 If no indicator lights illuminate, the
system is not enabled.
 If the red indicator light illuminates
any time other than immediately
after the engine switch switch> is turned IGNITION ON
mode , the system may
be malfunctioning or the backup
battery may be depleted. Contact
any authorized Lexus retailer or
Lexus authorized repairer, or any
reliable repairer.

years or more.
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 con- nect 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 Answer- ing Point (PSAP) and thus will not be able to make emergency calls and
report to the emergency departments even though the system tries to con-nect to the Public Safety Answering
Point (PSAP).
• When the vehicle is out of the cellular
phone service area, the Emergency Call cannot be made.
• When any related equipment (such as the “SOS” button panel, indicator lights, microphone, speaker, DCM,
antenna, or any wires connecting the equipment.) has an abnormality, is damaged or broken, the Emergency
Call cannot be made.
• During the Emergency Call, the sys-
tem makes repeated attempts to con- nect to the Public Safety Answering Point (PSAP). However, if it cannot
connect to the Public Safety Answer- ing Point (PSAP) due to poor radio wave reception, the system may not be
able to connect to the cellular network and the call may finish without con-necting. The red indicator light will
blink for approximately 30 seconds to indicate this disconnection.
• This device may not function if a shock is applied to it.

display. (P.92)
The illustration used is intended as an
example, and may differ from the image
that is actually displayed on the multi-infor-
mation display.
■Routine tire inflation pressure checks
The tire pressure warning system does not
replace routine tire inflation pressure checks. Make sure to check tire inflation pressure as part of your routine of daily
vehicle checks.
■Situations in which the tire pressure warning system may not operate prop-
erly
●In the following cases, the tire pressure
warning system may not operate prop- erly.• 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 extremely higher than the specified level.• If wheels without tire pressure warning
valves and transmitters are used. • If the ID code on the tire pressure warn-ing valves and transmitters is not regis-
tered in the tire pressure warning
computer.
●Performance may be affected in the fol-
lowing 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 wireless communication device
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 rap-
idly for example when a tire has burst, the warning may not function.
■Warning performance of the tire pres-sure warning system
The warning of the tire pressure warning system will change in accordance with the
conditions 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.
