properly or the danger that it
may work in situations where it
should not be working.
Installing electronic devices and
radios increases the risk of
cyber attacks through the
installed parts, which may lead
to unexpected accidents and
leakage of personal informa-
tion. Toyota does not make any
guarantees for problems caused
by installing non-genuine Toyota
products.
The installation of a mobile
two-way radio system in your
vehicle could affect electronic
systems such as:
Multiport fuel injection sys-
tem/sequential multiport fuel
injection system
 Toyota Safety Sense 3.0
 Anti-lock brake system
 SRS airbag system
 Seat belt pretensioner system
Be sure to check with your Toy-
ota dealer for precautionary
measures or special instructions
regarding installation of a mobile
two-way radio system.
High voltage parts and cables
on the hybrid vehicles emit approximately the same amount
of electromagnetic waves as the
conventional gasoline powered
vehicles or home electronic
appliances despite of their elec-
tromagnetic shielding.
Unwanted noise may occur in
the reception of the mobile
two-way radio.
This vehicle is equipped with
sophisticated computers that
record certain data regarding
vehicle controls and operations.

Data recorded by the comput-
ers
*1
Certain data, such as the following,
is recorded dependi ng on the oper-
ation timing and status of each
function.
• Basic vehicle behavior related data (engine speed/electric motor
speed, accelerator/brake pedal
operation, vehicle speed, etc.)
• Operating state of the driving support systems (recorded during
system operation, includes basic
vehicle behavior related data)
• Driving support system sensor data
• Image data (images from the front, rear and side cameras)

• Location information
These computers do not record
conversations, sounds, or
images of the inside of the vehi-
cle.

For safety and security
Front impact sensors
Airbag sensor assembly
Your vehicle is equipped with ADVANCED AIRBAGS designed
based on the US motor vehicle safety standards (FMVSS208). The
airbag sensor assembly (ECU) cont rols airbag deployment based on
information obtained from the sensors etc. shown in the system
components diagram above. This in formation includes crash sever-
ity and occupant information. As the airbags deploy, a chemical
reaction in the inflators quickly fills the airbags with non-toxic gas to
help restrain the motion of the occupants.
■If the SRS airbags deploy
(inflate)
●Slight abrasions, burns, bruising
etc., may be sustained from SRS
airbags, due to the extremely high
speed deployment (inflation) by
hot gases.
●A loud noise and white powder will
be emitted.
●Parts of the airbag module (steer-
ing wheel hub, airbag cover and
inflator) as well as the front seats,
parts of the front and rear pillars,
and roof side rails, may be hot for
several minutes. T he airbag itself
may also be hot.
●The windshield may crack.
●The hybrid system will be stopped
and fuel supply to the engine will
be stopped. ( P. 8 6 )
●The brakes and st op lights will be
controlled automatically. ( P.267)
●The interior lights will turn on auto-
matically. ( P.287)
●The emergency flashers will turn
on automatically. ( P.362)
●For Safety Connect subscribers, if
any of the following situations
occur, the system is designed to
send an emergency call to the
response center, notifying them of
the vehicle’s location (without
needing to push the “SOS” button)
and an agent will attempt to speak with the occupants to ascertain
the level of emergency and assis-
tance required. If the occupants
are unable to communicate, the
agent automatically treats the call
as an emergency and helps to dis-
patch the necessary emergency
services. (
P. 7 2 )
• An SRS airbag is deployed.
• A seat belt pretensioner is acti-
vated.
• The vehicle is involved in a severe
rear-end collision.
■SRS airbag deployment condi-
tions (SRS front airbags)
●The SRS front airbags will deploy
in the event of an impact that
exceeds the set threshold level
(the level of forc e corresponding
to an approximately 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 in the follow-
ing situations:
• If the vehicle strikes an object, such as a parked vehicle or sign
pole, which can move or deform
on impact
• If the vehicle is involved in an underride collision, such as a colli-
sion in which the front of the vehi-
cle “underrides”, or goes under,
the bed of a truck
●Depending on the type of collision,
it is possible that only the seat belt

861-4. Hybrid system
When a certain level of impact is
detected by the impact sensor,
the emergency shut off system
blocks the high voltage current
and stops the fuel pump to mini-
mize the risk of electrocution
and fuel leakage. If the emer-
gency shut off system activates,
your vehicle will not restart. To
restart the hybrid system, con-
tact your Toyota dealer.
A message is automatically dis-
played when a malfunction
occurs in the hybrid system or
an improper operation is
attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions.
■If a warning light comes on, a
warning message is displayed,
or the 12-volt battery is discon-
nected
The hybrid system may not start. In this case, try to start the system
again. If the “READY” indicator does
not come on, contact your Toyota
dealer.

The daytime running lights remain
on after they illumi nate, even if the
parking brake is set again.
●For the U.S.A.: Daytime running
lights can be turned off by operat-
ing the switch.
●Compared to turning on the head-
lights, the daytime running light
system offers gr eater durability
and consumes less electricity, so
it can help improve fuel economy.
■Headlight control sensor
The sensor may not function prop-
erly if an object is placed on the sen-
sor, or anything that blocks the
sensor is affixed to the windshield.
Doing so interfere s with the sensor
detecting the level of ambient light
and may cause the automatic head-
light system to malfunction.
■Automatic light off system
