The Toyota Safety Sense 2.0
consists of the following
drive assist systems and
contributes to a safe and

WARNING
■ Toyota Safety Sense 2.0
The Toyota Safety Sense 2.0 is
designed to operate under the
assumption that the driver will
drive safely, and is designed to
help reduce the impact to the
occupants and the vehicle in the
case of a collision or assist the
driver in normal driving condi-
tions.
As there is a limit to the degree of
recognition accuracy and control
performance that this system can
provide, do not overly rely on this
system. The driver is always
responsible for paying attention to
the vehicle’s surroundings and
driving safely.

■ If a warning message is displayed on the multi-information display
A system may be temporarily unavailable or there may be a malfunction in
the system.
● In the following situations, perform the actions specified in the table. When
the normal operating conditions are detected, the message will disappear
and the system will become operational.
If the message does not disappear, contact your Toyota dealer.
WARNING
● Do not allow bright lights to
shine into the front camera.
● Do not dirty or damage the front

● 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.
If the message does not disappear, contact your Toyota dealer.
• When the temperature around the radar sensor is outside of the opera-
tional range, such as when the vehicle is in the sun or in an extremely cold
environment
•When the front camera cannot detect objects in front of the vehicle, such
as when driving in the dark, snow, or fog, or when bright lights are shining
into the front camera
•Depending on the conditions in the vicinity of the vehicle, the radar may
judge the surrounding environment can not be properly recognized. In that
Situation Actions
When the area around a camera is
covered with dirt, moisture (fogged
up, covered with condensation, ice,
etc.), or other foreign matter
Using the wiper and A/C function,
remove the dirt and other attached
matter. (P.413, 418)
When the temperature around the
front camera is outside 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 reflected from the
surface of the sunshade may cause
the temperature of the front camera
to become excessively 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-Collision System
Unavailable” is displayed.
Check whether there is attached
materials on the radar sensor and
radar sensor cover, and if there is,
remove it.

: If equipped
LTA (Lane Tracing
Assist)
*
While driving on a road with
clear white (yellow) lane
lines, the LTA system warns
the driver if the vehicle may
deviate from the current
lane or course*, and also
can slightly operate the
steering wheel to help avoid
deviation from the lane or
course*. Also, while the
dynamic radar cruise con-
trol with full-speed range is
operating, this system will
operate the steering wheel
to maintain the vehicle’s
lane position.
The LTA system recognizes
white (yellow) lane lines or a
course*using the front cam-
era. Additionally, it detects
preceding vehicles using
the front camera and radar.
*
: Boundary between asphalt and
the side of the road, such as
grass, soil, or a curb
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.
● When not using the LTA system,
use the LTA switch to turn the
system off.
■ 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.

WARNING
● 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 pressure is low.
● During emergency towing.
■ 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 grille 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.

play is displayed (P.212) and
the preceding vehicle changes
lanes. (Your vehicle may follow
the preceding vehicle and also
change lanes.)

■ Hands off steering wheel warn-
ing
In the following situations, a warning
message urging the driver to hold
the steering wheel and the symbol
shown in the illustration are dis-
played on the multi-information dis-
play to warn the driver. The warning
stops when the system determines
that the driver holds the steering
wheel. Always keep your hands on
the steering wheel when using this
system, regardless of warnings.
● When the system determines that
the driver is driving without hold-
ing the steering wheel while the
system is operating
If the driver continues to keep their
hands off of the steering wheel, the
buzzer sounds, the driver is warned
and the function is temporarily
canceled. This warning also oper-
ates in the same way when the
driver continuously operates the
steering wheel only a small amount.
● When the system determines that
the vehicle may deviate from the
lane while driving around a curve
while the lane centering function is
operating.
Depending on the vehicle condition
and road conditions, the warning
may not operate. Also, if the system
determines that the vehicle is driv-
ing around a curve, warnings will
occur earlier than during
straight-lane driving.
● When the system determines that
the driver is driving without hold-

driver is warned. Each time the
buzzer sounds, the continuing time
of the buzzer becomes longer.
■ Vehicle sway warning function
When the system determines that
the vehicle is swaying while the
vehicle sway warning function is
operating, a buzzer sounds and a
warning message urging the driver
to rest and the symbol shown in the
illustration are simultaneously dis-
played on the multi-information dis-
play.
Depending on the vehicle and road
conditions, the warning may not
operate.
■ Warning message
If the following warning message is
displayed on the multi-information
display and the LTA indicator illumi-
nates in orange, follow the appropri-
ate troubleshooting procedure. Also,
if a different warning message is
displayed, follow the instructions
displayed on the screen.
● “LTA Malfunction Visit Your
Dealer”
The system may not be operating
properly. Have the vehicle inspected
by your Toyota dealer.
● “LTA Unavailable”
