671-3. Emergency assistance
1
For safety and security
The following indicator light pat-
terns indicate specific system
usage conditions:
Green indicator light on =
Active service
 Green indicator light flashing
= Safety Connect call in pro-
cess
 Red indicator light (except at
vehicle start-up) = System
malfunction (contact your Toy-
ota dealer)
 No indicator light (off) =

■Automatic Collision Notifi-
cation
In case of either airbag deploy-
ment or severe rear-end colli-
sion, the system is designed to
automatically call the response
center. The responding agent
receives the vehicle’s location
and attempts to speak with the
vehicle occupants to assess the
level of emergency. If the occu-
pants are unable to communi-
cate, the agent automatically
treats the call as an emergency,
contacts the nearest emer-
gency services provider to
describe the situation, and
requests that assistance be sent
to the location.
■Stolen Vehicle Location
If your vehicle is stolen, Safety
Connect can work with local
authorities to assist them in
locating and recovering the
vehicle. After filing a police
report, call the Customer Experi-
ence Center at 1-800-331-4331
in the United States,
1-877-855-8377 in Puerto Rico
or 1-888-869-6828 in Canada,
and follow the prompts for
Safety Connect to initiate this
service.
In addition to assisting law
enforcement with recovery of a
stolen vehicle, Safety-Con-
nect-equipped vehicle location
data may, under certain circum-
stances, be shared with third
parties to locate your vehicle.
Further information is available
at Toyota.com in the United
States, Toyotapr.com in Puerto
Rico and Toyota.ca in Canada.
■Emergency Assistance But-
ton (“SOS”)
In the event of an emergency on
the road, push the “SOS” button
to reach the Safety Connect
response center. The answer-
ing agent will determine your
vehicle’s location, assess the
emergency, and dispatch the
necessary assistance required.
If you accidentally press the “SOS”
button, tell the response-center
agent that you are not experiencing
an emergency.

■If a warning message is displayed on the multi-information display
A system may be tempor arily unavailable or there may be a malfu nction in
the system.
●In the following situations, perform the actions specified in t he table. When
the normal operating conditions are detected, the message will disappear
and the system will be come operational.
If the message does not disapp ear, contact your Toyota dealer.
●In the following situations, if the situation has changed (or the vehicle has
been driven for some time) and the normal operating conditions are
detected, the message will disappear and the system will become opera-
tional.
SituationActions
When the area around a camera is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or other foreign matterUsing the wiper and A/C function,
remove the dirt and other attached
matter ( P.330).
When the temperature around the
front camera is out side of the opera-
tional range, such as when the vehi-
cle is in the sun or in an extremely
cold environment
If the front camera is hot, such as
after the vehicle had been parked in
the sun, use the air conditioning sys-
tem to decrease the temperature
around the front camera.
If a sunshade was used when the
vehicle was parked, depending on its
type, the sunlight r eflected from the
surface of the sunshade may cause
the temperature of the front camera
to become exce ssively high.
If the front camera is cold, such after
the vehicle is parked in an extremely
cold environment, use the air condi-
tioning system to increase the tem-
perature around the front camera.
The area in front of the front camera
is obstructed, such as when the
hood is open or a sticker is attached
to the part of the windshield in front
of the front camera.
Close the hood, remove the sticker,
etc. to clear the obstruction.
When “Pre-Collisi on System Radar
In Self Calibration Unavailable See
Owner's Manual” is displayed.Check whether there is attached
materials on the radar sensor and
radar sensor cover, and if there is,
remove it.

2544-5. Using the driving support systems
WARNING
■Before using LTA system
●Do not rely solely upon the LTA
system. The LTA system does
not automatically drive the vehi-
cle or reduce the amount of
attention that must be paid to
the area in front of the vehicle.
The driver must always assume
full responsibility for driving
safely by paying careful atten-
tion to the surrounding condi-
tions and operating the steering
wheel to correct the path of the
vehicle. Also, the driver must
take adequate breaks when
fatigued, such as from driving
for a long period of time.
●Failure to perform appropriate
driving operations and pay care-
ful attention may lead to an
accident, resulting in death or
serious injury.
■Situations unsuitable for LTA
system
In the following situations, use the
LTA switch to turn the system off.
Failure to do so may lead to an
accident, resulting in death or
serious injury.
●Vehicle is driven on a road sur-
face which is slippery due to
rainy weather, fallen snow,
freezing, etc.
●Vehicle is driven on a snow-cov-
ered road.
●White (yellow) lines are difficult
to see due to rain, snow, fog,
dust, etc.
●Vehicle is driven in a temporary
lane or restricted lane due to
construction work.
●Vehicle is driven in a construc-
tion zone.
●A spare tire, tire chains, etc. are
equipped.
●When the tires have been
excessively worn, or when the
tire inflation p ressure is low.
●When your vehicle is towing a
trailer or during emergency tow-
ing.
■Preventing LTA system mal-
functions and operations per-
formed by mistake
●Do not modify the headlights or
place stickers, etc. on the sur-
face of the lights.
●Do not modify the suspension
etc. If the suspension etc. needs
to be replaced, contact your
Toyota dealer.
●Do not install or place anything
on the hood or grille. Also, do
not install a gr ille guard (bull
bars, kangaroo bar, etc.).
●If your windshield needs
repairs, contact your Toyota
dealer.
■Conditions in which functions
may not operate properly
In the following situations, the
functions may not operate prop-
erly and the vehicle may depart
from its lane. Drive safely by
always paying careful attention to
your surroundings and operate
the steering wheel to correct the
path of the vehicle without relying
solely on the functions.

2864-5. Using the driving support systems
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 cloth-
ing.
■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.
●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.
●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 carrier, or snow plow.
●If the front of the v ehicle is raised

●If the front of the vehicle is raised
or lowered due to the carried load
●When turning while backing up
●When a vehicle turns into the
detection area
■Situations in which the system
may operate even if there is no
possibility of a collision
Instances of the RCTA function
unnecessary detec ting a vehicle
and/or object may increase in the
following situations:
●When the parking space faces a
street and vehicles are being
driven on the street
●When the distanc e between your
vehicle and metal objects, such as
a guardrail, wall, sign, or parked
vehicle, which may reflect electri-
cal waves toward the rear of the
vehicle, is short
●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
●When a vehicle passes by the
side of your vehicle
●When a detected vehicle turns
while approaching the vehicle
●When there are spinning objects
near your vehicle such as the fan
of an air conditioning unit
●When water is splashed or
sprayed toward the rear bumper,
such as from a sprinkler
●Moving objects (f lags, exhaust
fumes, large rain droplets or
snowflakes, rain water on the road
surface, etc.)
●When the distance between your
vehicle and a guardrail, wall, etc.,
that enters the detection area is
short

WARNING
■Cautions regarding the use of
the system
Do not overly rely on the system,
as doing so may lead to an acci-
dent.
Always drive while checking the
safety of the surroundings of the
vehicle.
Depending on the vehicle and
road conditions, weather, etc., the
system may not operate.
The detection capa bilities of sen-
sors and radars are limited.
Always drive while checking the
safety of the surroundings of the
vehicle.
●The driver is solely responsible
for safe driving. Always drive
carefully, taking care to observe
your surroundings. The Parking
Support Brake system is
designed to provide support to
lessen the severity of collisions.
However, it may not operate in
some situations.
●The Parking Support Brake sys-
tem is not designed to stop the
vehicle completely. Additionally,
even if the system has stopped
the vehicle, it is necessary to
depress the brake pedal imme-
diately as brake control will be
canceled after approximately 2
seconds.
●It is extremely dangerous to
check the system operations by
intentionally driving the vehicle
into the direction of a wall, etc.
Never attempt such actions.
■When to disable the Parking
Support Brake
