HIGHLANDER HV_U
Please note that this manual
applies to explains all models
and all equipment, including
options. Therefore, you may find
some explanations for equip-
ment not installed on your vehi-
cle.
All specifications provided in this
manual are current at the time of
printing. However, because of
the Toyota policy of continual
product improvement, we
reserve the right to make
changes at any time without
notice.
Depending on specifications,
the vehicle shown in the illustra-
tions may differ from your vehi-
cle in terms of color and
equipment.
Approximately five hours after
the hybrid system is turned off,
you may hear sound coming
from under the vehicle for sev-
eral minutes. This is the sound
of a fuel evaporation leakage
check and, it does not indicate a
malfunction.A wide variety of non-genuine
spare parts and accessories for
Toyota vehicles are currently
available in the market. You
should know that Toyota does
not warrant these products and
is not responsible for their per-
formance, repair, or replace-
ment, or for any damage they
may cause to, or adverse effect
they may have on, your Toyota
vehicle.
This vehicle should not be modi-
fied with non-genuine Toyota
products. Modification with
non-genuine Toyota products
could affect its performance,
safety or durability, and may
even violate governmental regu-
lations. In addition, damage or
performance problems resulting
from the modification may not
be covered under warranty.
Also, remodeling like this will
have an effect on advanced
safety equipment such as Toy-
ota Safety Sense 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:
Hybrid system
 Multiport fuel injection sys-
tem/sequential multiport fuel
injection system
 Toyota Safety Sense 2.5 +
 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.
The vehicle is equipped with
sophisticated computers that will
record certain data, such as: • Engine speed/Electric motor
speed (traction motor speed)
• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the driving assist systems
• Images from the cameras
Your vehicle is equipped with cam-
eras. Contact your Toyota dealer for
the location of re cording cameras.
The recorded data varies
according to the vehicle grade
level and options with which it is
equipped.
These computers do not record
conversations 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
Toyota without notification to you.
Data usage
Toyota may use the data recorded
in this computer to diagnose mal-
functions, conduct research and
development, and improve quality.
Toyota will not disclose the
recorded data to a third party
except:
• With the consen t of the vehicle
owner or with the consent of the
lessee if the vehicle is leased
• In response to an official request by the police, a court of law or a
government agency
• For use by Toyota in a lawsuit
• For research purposes where the

361-1. For safe use
HIGHLANDER HV_U
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. 7 8 )
●All of the doors will be unlocked.
( P.132)
●The brakes and st op lights will be
controlled automatically. ( P.326)
●The interior lights will turn on auto-
matically. ( P.364)
●The emergency flashers will turn
on automatically. ( P.458)
●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. 6 5 )
• 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
pretensioners and SRS seat cush-
