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 1 )
●All of the doors will be unlocked.
( P.116)
●The brakes and st op lights will be
controlled automatically. ( P.383)
●The interior lights will turn on auto-
matically. ( P.420)
●The emergency flashers will turn
on automatically. ( P.502)
●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 0 )
• 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:

to OFF, the ligh t will go off auto-
matically after 20 minutes.
■Back door closer
In the event that the back door is left
slightly open, the back door closer
will automatically close it to the fully
closed position.
Whatever the state of the power
switch, the back door closer oper-
ates.
■Power back door operating con-
ditions
The power back door can automati-
cally open and close under the fol-
lowing conditions:
●When the power back door sys-
tem is enabled. ( P.135)

tem is disabled, the power back
door does not ope rate but it can
be opened and closed by hand.
●When the power back door auto-
matically opens, if an abnormality
due to people or objects is
detected, oper ation will stop.
■Jam protection function
Sensors are equipped on both sides
of the power back door. If anything
obstructs the power back door while
it is closing, the b ack door will auto-
matically operate in the opposite direction or stop.
■Fall-down protection function
While the power back door is open-
ing automatically, applying exces-
sive force to it will stop the opening
operation to prevent the power back
door from suddenly shutting.
■Back door closing assist
If the back door is lowered manually
when the back door is stopped at an
open position, the back door will
fully close automatically.
■Back door reserve lock function
This function is a function which
reserves locking of all doors, before-
hand, when the power back door is
open.

Driving
The system can detect the fol-
lowing (The detectable objects
differs depending on the func-
tion.):
 Vehicles
 Bicyclists 
Pedestrians
■Pre-collision warning
When the system determines
that the possibility of a frontal
collision is high, a buzzer will
sound and a warning message
will be displayed on the multi-
information display to urge the
driver to take evasive action.
“BRAKE!”
■Pre-collision brake assist
When the system determines
that the possibility of a frontal
collision is high, the system
applies greater braking force in
relation to how strongly the
brake pedal is depressed.
■Pre-collision braking
If the system determines that
the possibility of a frontal colli-
sion is extremely high, the
brakes are automatically applied
to help avoid the collision or
reduce the impact of the colli-
sion.
PCS (Pre-Collision Sys-
tem)
The pre-collision system
uses a radar sensor and
front camera to detect
objects ( P.249) in front of
the vehicle. When the sys-
tem determines that the
possibility of a frontal colli-
sion with an object is high, a
warning operates to urge
the driver to take evasive
action and the potential
brake pressure is increased
to help the driver avoid the
collision. If the system
determines that the possi-
bility of a frontal collision
with an object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the col-
lision.
The pre-collision system can
be disabled/enabled and the
warning timing can be
changed. ( P.253)

tions.( P.247, 519)
■When the sensor may not be
correctly detecting the vehicle
ahead
In the case of the following and
depending on the conditions, oper-
ate the brake pedal when decelera-
tion of the system is insufficient or
operate the accelerator pedal when
acceleration is required.
As the sensor may not be able to
correctly detect these types of vehi-
cles, the approach warning
(  P.282) may not be activated.
●Vehicles that cut in suddenly
●Vehicles traveling at low speeds
●Vehicles that are not moving in the
same lane
●Vehicles with small rear ends
(trailers with no load on board,
etc.)
●Motorcycles traveling in the same
lane
●When water or snow thrown up by
the surrounding vehicles hinders
the detecting of the sensor
●When your vehicle is pointing
upwards (caused by a heavy load
in the luggage compartment, etc.)
●Preceding vehicle has an
extremely high ground clearance
●When the vehicle is towing a
trailer or during emergency tow-
ing.
●When the vehicle is lifted up,
except in the following cases.
• When using a Toyota official lift kit up to 4 in. (101 mm), including tire
height. Aftermarket lift kits may
degrade system performance.
■Conditions under which the
vehicle-to-vehic le distance con-
trol mode may not function cor-
rectly
In the case of the following condi-
tions, operate the brake pedal (or
accelerator pedal, depending on the
situation) as necessary.
As the sensor may not be able to
correctly detect vehicles ahead, the
system may not operate properly.

2 Press or to select
“Trailer Settings” and then
press and hold .
3 According to the display,
select the desired setting and
then press . ( P.102)
■Auto Trailer Detection (ATD)
Auto Trailer Detect ion (ATD) detects
if a trailer is attached by using the
Trailer Brake Controller (TBC) or the
Blind Spot Monitor (BSM) sensors.
●Trailers that use TBC can be
detected by using the 7-pin trailer
brake connectors.
●Other types of trailers can be
detected using the BSM sensors.
●When a trailer is detected via BSM
or TBC, RCTA function will be dis-
abled.
●As soon as the tra iler is detected,
the detectio n area will be
extended to a maximum length of
approximately 16 ft. (15 m) from
the rear bumper of the truck.
●If the trailer does not have a 7-pin
connector, or the 7-pin connector
is not engaged, the trailer is
detected via the BSM sensor. In
this case PKSB (i f equipped) and
Intuitive parking assist functions
will not be disabled.
●For trailer auto detection without
engagement of 7-pin connector,
the vehicle should be moving for-
ward at speed of above 0.6 mph
(1 km/h) for at least 10 seconds.
●ATD function is triggered at every
power switch on/off cycle or if the
vehicle is stopped in shift the shift
lever is in P or N for more than 90
seconds.
●Trailer detection vis BSM sensors
may be delayed if the vehicle is in
a crowded environment such as
busy parking lot, area surrounded
with trees (camping ground) or in
an environment with objects in the
immediate environment that pre-
vent sensors from sufficiently
detecting the trailer.
■Trailer Length Detection (TLD)
●Once a trailer is detected and if
the trailer length in the meter is
selected as “Auto”, the TLD func-
tion will estimate the trailer length
using the Blind Spot Monitor sen-
sors.
In order to estimate the trailer length
with TLD function and detection
area, make at least two 90 degree
turns.
If the trailer length is entered manu-
ally via multi-information display
input, the detection area is also
adjusted to exceed the length of the
trailer.
●Depending on some trailer types
and the dimensions of the trailer
TMW performance may be
degraded.

tion of your vehicle
■Situations in which the system
may not operate properly
Certain vehicle conditions and the
surrounding environment may affect
the ability of a sensor to correctly
detect objects. Particular instances
where this may occur are listed
below.
●There is dirt, snow, water drops or
ice on a sensor. (Cleaning the
sensors will resolve this problem.)
●A sensor is frozen. (Thawing the
area will resolve this problem.)
In especially cold weather, if a
sensor is frozen the sensor dis-
play may be displayed abnormally,
or objects, such as a wall, may not
be detected.
●When a sensor or the area around
a sensor is extremely hot or cold.
●On an extremely bumpy road, on
an incline, on gravel, or on grass.

sonic waves are near the vehicle
●A sensor is coated with a sheet of
spray or heavy rain.
●If objects draw too close to the sensor.
●When a pedestrian is wearing
clothing that does not reflect ultra-
sonic waves (ex. skirts with gath-
ers or frills).
●When objects that are not perpen-
dicular to the ground, not perpen-
dicular to the vehicle traveling
direction, uneven, or waving are in
the detection range.
●Strong wind is blowing
●When driving in inclement weather
such as fog, snow or a sandstorm
●When an object that cannot be
detected is between the vehicle
and a detected object
●If an object such as a vehicle,
motorcycle, bicycle or pedestrian
cuts in front of the
vehicle or runs
out from the side of the vehicle
●If the orientation of a sensor has
been changed due to a collision or
other impact
●When equipment that may
obstruct a sensor is installed, such
as a towing eyelet, bumper pro-
tector (an additional trim strip,
etc.), bicycle car rier, or snow plow
