■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. 1 3 0 )
●The battery becomes depleted even if the electronic key is not used because the
key always receives radio waves. If the smart access system with push-button start
or the wireless remote control does not operate, or the detection area becomes
smaller, the battery may be depleted. Replace the battery when necessary.
( P. 4 7 2 )
●To avoid serious deterioration, do not leave the electronic key within 3 ft. (1 m) 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

CAUTION
■Caution regarding interference with electronic devices
●People with implantable cardiac pacemakers, cardiac resynchronization therapy-
pacemakers or implantable cardioverter defibrillators should keep away from the
smart access system with push-button start antennas. (P. 1 2 8 )
The radio waves may affect the operation of such devices. If necessary, the entry
function can be disabled. Ask your Lexus dealer for details, such as the frequency
of radio waves and timing of the emitte d 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 your Lexus dealer for details on disabling the entry function.
■When using the smart access system with push-button start and operating the
power windows or moon roof
Operate the power window or moon roof af ter 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 access system with
push-button start. It is possible for chil dren and other passengers to get caught in
the power window or moon roof.

Important! Read this information before using Safety Connect.
■Exposure to radio frequency signals
The Safety Connect system installed in your vehicle is a low-power
radio transmitter and receiver. It receives and also sends out radio fre-
quency (RF) signals.
In August 1996, the Federal Communications Commission (FCC)
adopted RF exposure guid elines with safety levels for mobile wireless
phones. Those guidelines are consistent with the safety standards previ-
ously set by the following U.S. and international standards bodies.
●ANSI (American National Standards Institute) C95.1 [1992]
●NCRP (National Council on Radi ation Protection and Measure-
ment) Report 86 [1986]
●ICNIRP (International Commission on Non-Ionizing Radiation Pro-
tection) [1996]
Those standards were based on comprehensive and periodic evalua-
tions of the relevant scientific litera ture. Over 120 scientists, engineers,
and physicians from universities, and government health agencies and
industries reviewed the available body of research to develop the ANSI
Standard (C95.1).
The design of Safety Connect co mplies with the FCC guidelines in
addition to those standards.

■If the tread on snow tires wears down below 0.16 in. (4 mm)
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.
• 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.
*
• If tires not equipped with 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.
*: 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 that 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 correc tly 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 rapi dly for example when a tire has burst, the
warning may not function.
