High voltage componentsTake care when handling the hybrid system, as it contains a high voltage
system (about 650V at maximu m) as well as parts that become
extremely hot when the hybrid system is operating. Obey the caution
labels attached to the vehicle. Power control unit

■Hybrid battery air vent
Hybrid battery air vent
There is an air intake vent on the
package tray for the purpose of
cooling the hybrid battery (trac-
tion battery). If the vent becomes
blocked, the hybrid battery may
overheat, leading to a reduction in
hybrid battery output.
Emergency shut off system
The emergency shut off system blocks off the high voltage current and
stops the fuel pump to minimize the risk of electrocution and fuel leakage
when a certain level of impact is detected by the impact sensor. If the
emergency shut off system activates, your vehicle will not restart. To
restart the hybrid system, contact your Lexus dealer.
Energy monitor/consumption screenYou can view the status of your hybrid system on the multi-information
display ( →P. 166) and the touch screen ( →P. 240). The following images
are examples only, and may vary slightly from actual conditions.
■ Energy monitor
● How to display on the touch screen:
Press .
Touch on the “Information” screen.
If the “Consumption” screen is displayed, touch .
● How to display on the multi-information display:
Push the “DISP” switch on the steering wheel several times to
select the energy monitor display.

■Operation signals
●Doors: A buzzer sounds and the emergency flashers flash to indicate that the
doors have been locked/unlocked. (Locked: Once; Unlocked: Twice)
●Windows and moon roof: A buzzer sounds when the windows and moon roof
begin to close.
■Conditions affecting operation
The smart access system with push-button start uses weak radio waves. In the fol-
lowing situations, the communication between the electronic key and the vehicle
may be affected, preventing the smart access system with push-button start. Wire-
less remote control, and immobilizer system from operating properly:
(Way of coping: →P. 5 5 0 )
●When the electronic key battery is depleted
●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 devices
●When the electronic key is in contact with, or is covered by the following metal-
lic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs
●When multiple electronic keys are in the vicinity
●When other wireless keys (that emit radio waves) are being used nearby
●When carrying or using the electronic key together with the following devices
that emit radio waves
• Another vehicle’s electronic key or a wireless key that emits radio waves
• Personal computers or personal digital assistants (PDAs)
• Digital audio players
• Portable game systems
●If window tint with a metallic content or metallic objects are attached to the rear
window

CAUTION
■Child restraint lock function belt precaution
Do not allow children to play with the child restraint lock function belt. If the belt
becomes twisted around a child’s neck, it will not be possible to pull the belt out
leading to choking or other serious injuries that could result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used to cut
the belt.
■Seat belt damage and wear
●Do not damage the seat belts by allowing the belt, plate or buckle to be jammed
in the door.
●Inspect the seat belt system periodically. Check for cuts, fraying, and loose parts.
Do not use a damaged seat belt until it is replaced. Damaged seat belts cannot
protect an occupant from injury.
●Ensure that the belt and tab are locked and the belt is not twisted. If the seat belt
does not function correctly, immediately contact your Lexus dealer.
●Replace the seat assembly, including the belts, if your vehicle has been involved in
a serious accident, even if there is no obvious damage.
●Do not attempt to install, remove, modify, disassemble or dispose of a seat belt.
Have any necessary repairs carried out by your Lexus dealer. Inappropriate han-
dling of the pretensioner may cause it to activate or operate improperly and may
cause death or serious injury.
■Using a seat belt extender
●Do not wear the seat belt extender, if you can fasten the seat belt without the
extender.
●Do not use the seat belt extender when installing a child restraint system, because
the belt will not securely hold the chil d restraint system, increasing the risk of
death or serious injury in the event of a sudden stop, sudden swerve or accident.
●The personalized extender may not be safe on another vehicle, when used by
another person, or at a different seating position other than the one originally
intended.
■Precaution for pre-collision seat belts
Do not rely solely on the pre-collision system to avoid accidents. Always pay atten-
tion to the surrounding conditions, and drive safely and responsibly.

■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the set
threshold level (the level of force corresponding to a 12 - 18 mph [20 - 30 km/h]
frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be considerably higher if the vehicle strikes
an object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).
●It is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed threshold level, the SRS front airbags and the
seat belt pretensioners may not activate together.
●The SRS front passenger airbag will not activate, if there is not passenger sitting
in the front passenger seat. However, the front passenger airbag may deploy, if
luggage is put in the seat, or the seat belt is fastened, even if the seat is unoccu-
pied. (→P. 1 1 5 )
■SRS airbag deployment conditions (SRS side airbags and SRS curtain shield air-
bags)
●The SRS side airbags and SRS curtain shield airbags will deploy in the event of
an impact that exceeds the set threshold level (the level of force corresponding
to the impact force produced by a 3300 lb. [1500 kg] vehicle colliding with the
vehicle cabin from a direction perpendicular to the vehicle orientation at a
speed of 12 - 18 mph [20 - 30 km/h]).
●The SRS front side airbag on the passenger seat will not activate if there is no
passenger sitting in the front passenger seat. However, the front side airbag on
the passenger seat may deploy if luggage is put in the seat, or the seat belt is fas-
tened, even if the seat is unoccupied. ( →P. 1 1 5 )

■Conditions under which the SRS airbags may deploy (inflate), other than a colli-
sion
The SRS front airbags may also deploy if a serious impact occurs to the underside of
your vehicle. Some examples are shown in the illustration.
■Types of collisions that may not deploy the SRS airbag (front airbags)
The SRS front airbags are generally not designed to inflate if the vehicle is involved
in a side or rear collision, if it rolls over, or if it is involved in a low-speed frontal colli-
sion. But, whenever a collision of any type causes sufficient forward deceleration of
the vehicle, deployment of the SRS front airbags may occur.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or vehicle falling
●Collision from the side
●Collision from the rear
●Vehicle rollover
