In order to be effective, the SRS
airbags must deploy with tremen-
dous speed. The rapid deployment
of the SRS airbags makes the
SRS airbags themselves potential
sources of serious injury if an oc-
cupant is too close to an airbag,
or if an object or some part of his
or her body has been placed be-
tween the occupant and the airbag
at the time of deployment. This is
just one example of how the in-
structions in Section 2−2 of this
Owner ’s Manual will help ensure
proper use of the occupant re-
straint systems, and increase the
safety they can provide to you
and your family in the event of an
accident.
Toyota recommends you to read
the provisions in Section 2− 2 care-
fully and refer to them as needed
during your time of ownership of
this vehicle.Event data recorder
Your vehicle has computers that
monitor and control certain as-
pects of your vehicle. These com-
puters assist in driving and main-
taining optimal vehicle perfor-
mance. Besides storing data useful
for troubleshooting, there is a sys-
tem to record data in a crash or
a near car crash event. This is
called an Event Data Recorder
(EDR).
The SRS airbag sensor assembly
contains the EDR. In a crash or a
near car crash event, this device
may record some or all of the fol-
lowing information:
 Engine speed
 Whether the brake pedal was
applied or not
 Vehicle speed
 To what extent the accelerator
pedal was depressed
 Position of the transmission
selector lever
 Whether the driver and front
passenger wore the seat belts
or not
 Driver ’s seat position
 Front passenger ’s occupant

CAUTION
WARNING: Engine exhaust, some of its constitu-
ents, and a wide variety of automobile compo-
nents contain or emit chemicals known to the
State of California to cause cancer and birth de-
fects and other reproductive harm. In addition,
oils, fuels and fluids contained in vehicles as well
as waste produced by component wear contain or
emit chemicals known to the State of California
to cause cancer and birth defects or other repro-
ductive harm.
Battery posts, terminals and related accessories
contain lead and lead compounds. Wash your
hands after handling. Used engine oil contains
chemicals that have caused cancer in laboratory
animals. Always protect your skin by washing
thoroughly with soap and water.

Precautions for useof hybrid vehicle
The vehicle has both high voltage
DC and AC systems as well as a
12volt system. DC and AC high
voltage are both very dangerous
and can cause death or serious inju-
ry, severe burns and electric shock.
In order to avoid personal in-
juries, do not touch the high
voltage cables (orange col-
ored) and their connectors.
Follow the caution labels at-
tached to the high voltage
parts.
Do not remove or replace the
high voltage parts such as
the inverter unit (located in
the engine compartment), hy-
brid battery (located behind
rear seat), etc.
Do not touch the service plug
located in the left side trim
of the luggage compartment
without hybrid system techni-
cal training. (See “Precau-
tions for use” on page 14.)
This component is provided
to disable the high voltage
system in case of servicing at
a Toyota dealer.
CAUTIONIf an accident occurs
Pull your vehicle off the road,
push the “P” position switch,
stop the hybrid system and if
the key is inserted into key
slot, remove it.
In order to avoid personal in-
juries, do not touch any high
voltage wirings and their con-
nectors, and high voltage
parts (inverter unit, hybrid
battery, etc.).
If some exposed electric
wires are protruding inside or
outside of your vehicle, an
electric shock may occur.
Never touch the electric
wires.
If fluid leaks or gets in some
parts of the vehicle, never
touch it because it may be
electrolyte (strong alkali) from
the hybrid battery. If it gets
into your skin or eyes, wash
off immediately with a large
amount of water, if possible,
boric acid solution, and get
immediate medical attention
in order to help avoid serious
injury.
If a vehicle fire occurs, extin-
guish it using a fire extin-
guisher for the exclusive use
on electric fires. Or, use a
large amount of water to pre-
vent flammable gas from be-
ing generated from the batter-
ies.
