361-1. For safe use
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.323)
●The interior lights will turn on auto-
matically. ( P.362)
●The emergency flashers will turn 
on automatically. ( P.456)
●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- 

1403-2. Opening, closing and locking the doors
will automatically close it to the fully 
closed position.
●The back door closer can function 
when the power switch is in any 
mode.
●The back door can be opened 
using the back door opener switch 
even if the back door closer is 
operating.
■Power back door operating con-
ditions
If the following conditions are met, 
the power back door can be opened 
and closed automatically.
●When the power back door sys-
tem is enabled. ( P.528)
●When the power switch is in ON, 
one of the following conditions 
must be met in a ddition to the 
above conditions:
• The parking brake is engaged.
• The brake pedal is depressed.
• The shift lever is in P.
■Operation of the power back 
door
●When the power back door begins 
to operate, the emergency flash-
ers will flash twice and a buzzer 
will sound.
●When the power back door is dis-
abled, the power back door will 
not operate but  can be opened 
and closed manually.
●When the power back door is 
opening/closing, if the power back 
door becomes obstructed, opera-
tion will stop.
■Jam protection function
Sensors are installed on the right 
and left sides of the power back 
door. When the door is automati-
cally closing and the sensors are 
pushed due to an object being 
clamped, etc., the jam protection 
function operates.
From that position the door auto-
matically moves a little in the oppo-
site direction and then the function  stops.
■Back door reserve lock function
This function reserves the locking of 
the power back door when the 
power back door is open. If the fol-
lowing operations are performed, all 
of the doors except the power back 
door will lock and  then the power 
back door will lock when it is com-
pletely closed.
1 Close all of the doors, except the 
back door.
2 Perform an automatic closing 
operation of the power back door 
and lock the doors using the 
wireless remote control 
( P.131) or smart key system 
(  P.131) while the power back 
door is closing.
A buzzer sounds and the emer-
gency flashers flash to indicate that 
all the doors have been closed and 
locked.
●If the electronic key is placed 
inside the vehicle after starting a 
close operation via the door 
reserve lock function, the elec-
tronic key may become locked 
inside the vehicle.
●If the back door does not fully 
close due to the o peration of the 
jam protection function, etc., while 
the back door is automatically 
closing after a do or reserve lock 
operation is performed, the door 
reserve lock function is canceled 
and all the doors will unlock.
●Before leaving the vehicle, make 
sure that all the doors are closed 
and locked. 

2384-3. Operating the lights and wipers
windshield wipers are operating, if a 
front door is opened, the operation 
of the windshield wipers will be 
stopped to prevent anyone enter-
ing/exiting the vehicle from being 
sprayed by water from the wipers, 
provided the vehicle is stopped with 
the parking brake applied or the shift 
lever in P. When the front door is 
closed, wiper operation will resume.
Operating the   switch 
operates the rear wiper as fol-
lows.

WARNING
■Caution regarding the use of 
windshield wipers in AUTO 
mode (vehicles with 
rain-sensing windshield wip-
ers)
The windshield wipers may oper-
ate unexpectedly if the sensor is 
touched or the windshield is sub-
ject to vibration in AUTO mode. 
Take care that your fingers, etc. 
do not become caught in the 
windshield wipers.
■Caution regarding the use of 
washer fluid
When it is cold, do not use the 
washer fluid until  the windshield 
becomes warm. The fluid may 
freeze on the windshield and 
cause low visibility. This may lead 
to an accident, resulting in death 
or serious injury.
NOTICE
■When the washer fluid tank is 
empty
Do not operate the switch continu-
ally as the washer fluid pump may 
overheat.
■When a nozzle becomes 
blocked
In this case, contact your Toyota 
dealer.
Do not try to clear it with a pin or 
other object. The nozzle will be 
damaged.

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.
■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.
■Emergency steering assist
If the system determines that 
the possibility of a frontal colli-
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.252)
