301-1. For safe use
based on US motor vehicle safety standards (FMVSS208). The air-
bag sensor assembly (ECU) controls 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 of 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 parts
around the airbags may be hot for
several minutes. T he airbag itself
may also be hot.
●The windshield may crack.
●All of the doors will be unlocked.
(  P.105)
●The brakes and st op lights will be
controlled automatically. ( P.275)
●The interior lights will turn on auto-
matically. ( P.303)
●The emergency flashers will turn
on automatically. ( P.382)
●Fuel supply to the engine will be
stopped. (P.390)
●For Safety Connect subscribers, if
any of the followin g 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. (

• When an SRS airbag has been
deployed
• When a seat belt pretensioner has operated
• When the vehicle has been involved in a severe rear-end colli-
sion
■The SRS airbags deploy in a
frontal impact when
●The following SRS airbags will
deploy in the event of an impact
that exceeds a th reshold level
(level of force corresponding to an
approximately 12 - 18 mph [20 -
30 km/h] frontal collision with a
fixed wall that does not move or
deform):
• SRS front airbags
• SRS knee airbag
●The threshold level at which the
SRS airbags will deploy will be
higher than normal in the in the
following situations:
• When the vehicle collides with an
object, such as a parked vehicle
or sign pole, which moves or
deforms 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,
only the following may deploy:
• Seat belt pretensioners
●The SRS airbags for the front pas-
senger’s seat will not deploy if
there is no passe nger in the front
passenger seat. However, the

■Daytime running light system
●Vehicles without a smart key sys-
tem :The daytime running lights
illuminate using the same lights as
the headlights and illuminate
darker than the headlights.
Vehicles with a smart key system
:The daytime runni ng lights illumi-
nate using the sa me lights as the
parking lights and illuminate darker
than the parking lights.
●To make your vehicle more visible
to other drivers during daytime
driving, the daytime running lights
turn on automatically when all of
the following condi tions are met.
(The daytime running lights are
not designed for use at night.)
• The engine is running
• The parking brake is released
• The headlight switch is in the
or
* position
*: When the surroundings are bright
The daytime running lights remain
on after they illumi nate, even if the
parking brake is set again.
●Daytime running lights can be
turned off by operating 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 (if
equipped)
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 interferes with the sensor
detecting the level
of ambient light
and may cause t he automatic head-
light system to malfunction.
■Automatic light off system
●When the headlights are on: The
headlights and tail lights turn off
30 seconds after the driver’s door
is opened and closed if the engine
switch is turned to ACC or OFF.
(The lights turn off immediately if
on the key is pressed after all
the doors are closed.)
●When only the tail lights are on:
The tail lights turn off automati-
cally if the engine switch is turned
to ACC or OFF and the driver’s
door is opened.
To turn the lights on again, turn the
engine switch to ON, or turn the light
switch off once and then back to
or .
■Light reminder buzzer
A buzzer sounds when the engine
switch is turned t o OFF or ACC and
the driver’s door is opened while the
lights are turned on.
■Automatic headlight leveling
system (if equipped)
The level of the headlights is auto-
matically adjusted according to the
number of passengers and the load-
ing condition of the vehicle to
ensure that the headlights do not
interfere with o ther road users.
■Windshield wiper linked head-
light illumination (vehicles with
a headlight control sensor )
When driving during daytime with
the headlight switch turned to , if
the windshield wipers are used, the
headlights will turn o n automatically
after several se conds to help
enhance the visibility of your vehi-
cle.

PCS (Pre-Collision Sys-
tem)
The pre-collision system
uses sensors to detect
objects ( P.198) in the path
of the vehicle. When the
system determines that the
possibility of a frontal colli-
sion with a detectable
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 possibility of a collision
is extremely high, the
brakes are automatically
applied to help avoid the
collision or help reduce the
impact of the collision.
The pre-collision system
can be disabled/enabled
and the warning timing can
be changed. ( P.207)
WARNING
■For safe use
●Driving safely is solely the
responsibility of the driver. Pay
careful attention to the sur-
rounding conditions in order to
ensure safe driving.
Never use the pre-collision
system in place of normal
braking operations. This sys-
tem cannot help avoid or
reduce the impact of a colli-
sion in every situation.
Over-reliance on this system
to drive the vehicle safely may
lead to an accident resulting
in death or serious injury.
●Although the pre-collision sys-
tem is designed to help avoid or
help reduce the impact of a col-
lision, its effectiveness may
change according to various
conditions. Therefore, it may not
always be able to achieve the
same level of performance.
Read the followin g items care-
fully. Do not overl y rely on this
system and always drive care-
fully.

tance from the preceding vehicle.
■When the vehicle is stopped by
system control during follow-up
cruising
●When the “+RES” switch is
pressed while the vehicle is
stopped by system control, if the
preceding vehicle starts off within
approximately 3 seconds, fol-
low-up cruising will resume.
●If the preceding vehicle starts off
within approximately 3 seconds of
the vehicle being stopped by sys-
tem control, follo w-up cruising will
resume.
■Automatic cancellation of vehi-
cle-to-vehicle d istance control
mode
In the following situations, vehi-
cle-to-vehicle dista nce control mode
will be canceled automatically:
●When the brake control or output
restriction control of a driving sup-
port system operates
(For example: Pre-Collision Sys-
tem, drive-start control)
●When the parking brake has been
operated
●When the vehicle is stopped by
system control on a steep incline
●When any of the following are
detected while the vehicle is
stopped by system control:
• The driver’s seat belt is unfas- tened
• The driver’s door is opened
• Approximately 3 minutes have elapsed since the vehicle was
stopped
The parking brake may be actived

sor may not detect correctly
In the following situations, depend-
ing on the conditions, if the system
cannot provide sufficient decelera-
tion or acceleration is necessary,
operate the brake pedal or accelera-
tor pedal.
As the sensor may not be able to
correctly detect th ese types of vehi-
cles, the approach warning
(  P.226) may not operate.

Driving
If a sensor is dirty, the position of the
dirty sensor will be shown on the
display.
Also, due to ice forming on a sensor
at low temperatures, a warning
message may be displayed or the
sensor may not be able to detect an
object. Once the ice melts, the sys-
tem will return to normal.
If a warning message is displayed
even if the sensor is clean, there
may be a sensor malfunction. Have
the vehicle inspected by your Toyota
dealer.
■Sensor detection information
●The sensors may be able to only
detect objects near the front and
rear bumpers.
●The following situations may occur
during use.
• Depending on the shape of the
object and other factors, the
detection distance may shorten, or
detection may be impossible.
• Detection may be impossible if static objects draw too close to the
sensor.
• After the static object detection, there will be a short delay before a
graphic is shown on displays, and
warning buzzer sounds. Even at
low speeds, there is a possibility
that the object will come within the
sensor’s detecti on areas before
the display is shown and the warn-
ing beep sounds.
• It might be difficult to hear the buzzer due to the volume of the
audio system or air flow noise of
the air conditioning system.
• It may be difficult to hear the buzzer if buzzers for other sys-
tems are sounding.
■Objects which the system may
not be properly detected
The shape of the object may pre-
vent the sensor from detecting it.
Pay particular attention to the follow-
ing objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials
that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections
projecting outwards in the direc-
tion of your vehicle
●People may not be detected if
they are wearing certain types of
clothing.
■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. Part icular 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 froz en. (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.
●When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of ot her vehicles or
other devices which produce ultra-
sonic waves are near the vehicle
●A sensor is coated with a sheet of
spray or heavy rain.
