Approximately five hours after the
hybrid system is turned off, you may
hear sound coming from under the
vehicle for several minutes. This is the
sound of a fuel evaporation leakage
check and, it does not indicate a mal-
function.A wide variety of non-genuine spare
parts and accessories for Lexus vehi-
cles are currently available in the mar-
ket. You should know that Toyota does
not warrant these products and is not
responsible for their performance,
repair, or replacement, or for any dam-
age they may cause to, or adverse
effect they may have on, your Lexus
vehicle.
This vehicle should not be modified
with non-genuine Lexus products.
Modification with non-genuine Lexus
products could affect its performance,
safety or durability, and may even vio-
late governmental regulations. In addi-
tion, damage or performance
problems resulting from the modifica-
tion may not be covered under war-
ranty.
Also, remodeling like this will have an
effect on advanced safety equipment
such as Lexus Safety System + 2.5 and
there is a danger that it will not work
properly or the danger that it may work
in situations where it should not be
working.
The installation of a mobile two-way
radio system in your vehicle could
affect electronic systems such as:

the vehicle grade level and options with which it is equipped.
These computers do not record con-
versations or sounds, and only record
images outside of the vehicle in certain
situations.

Data Transmission
Your vehicle may transmit the data
recorded in these computers to Lexus
without notification to you.
Data usage
Lexus may use the data recorded in this
computer to diagnose malfunctions, con-
duct research and development, and
improve quality.
Lexus will not disclose the recorded data
to a third party except:
• With the consent of the vehicle owner or
with the consent of the lessee if the vehi-
cle is leased
• In response to an official request by the police, a court of law or a government
agency

transmitter and receiver. It receives
and also sends out radio frequency
(RF) signals.
In August 1996, the Federal Commu-
nications Commission (FCC) adopted
RF exposure guidelines with safety lev-
els for mobile wireless phones. Those
guidelines are consistent with the
safety standards previously set by the
following U.S. and international stan-
dards bodies.

shielding, and therefore emit approxi-
mately the same amount of electromag-
netic waves as conventional gasoline
powered vehicles or home electronic
appliances.
OYour vehicle may cause sound interfer-
ence in some third party-produced radio
parts.
QHybrid battery (traction battery)
The hybrid battery (traction battery) has a
limited service life. The lifespan of the
hybrid battery (traction battery) can change
in accordance with driving style and driving
conditions.
QStarting the hybrid system in an
extremely cold environment (for vehi-
cles sold in except Canada)
When the hybrid battery (traction battery)
is extremely cold (below approximately -
22°F [-30°C]) under the influence of the
outside temperature, it may not be possible
to start the hybrid system. In this case, try to
start the hybrid system again after the tem-
perature of the hybrid battery increases
due to the outside temperature increase
etc.
WARNING
QHigh voltage precautions
This vehicle has high voltage DC and AC
systems as well as a 12-volt system. DC
and AC high voltage is very dangerous
and can cause severe burns and electric
shock that may result in death or serious
injury.
ONever touch, disassemble, remove or
replace the high voltage parts, cables
or their connectors.
OThe hybrid system will become hot
after starting as the system uses high
voltage. Be careful of both the high
voltage and the high temperature, and
always obey the warning labels
attached to the vehicle.
ONever try to open the service plug
access hole located under the rear
seat (right side). The service plug is
used only when the vehicle is serviced
and is subject to high voltage.
QRoad accident cautions
Observe the following precautions to
reduce the risk of death or serious injury:
OPull your vehicle off the road, apply the
parking brake, shift the shift lever to P,
and turn the hybrid system off.
ODo not touch the high voltage parts,
cables and connectors.
OIf electric wires are exposed inside or
outside your vehicle, an electric shock
may occur. Never touch exposed
electric wires.
OIf a fire occurs in the hybrid vehicle,
leave the vehicle as soon as possible.
Never use a fire extinguisher that is not
meant for electric fires. Using even a
small amount of water may be danger-
ous.
OIf your vehicle needs to be towed, do
so with front wheels raised. If the
wheels connected to the electric
motor (traction motor) are on the
ground when towing, the motor may
continue to generate electricity. This
may cause a fire. ( P.361)
OCarefully inspect the ground under the
vehicle. If you find that liquid has
leaked onto the ground, the fuel sys-
tem may have been damaged. Leave
the vehicle as soon as possible.
