Pre-collision braking
The system may not operate in the following situations:
●
If a 12-volt battery terminal has been disconnected and reconnected and
then the vehicle has not been driven for a certain amount of time
●
If the shift lever is in R
●
When the VSC OFF indicator is illuminated (only the pre-collision warning
function will be operational)
■
Object detection function
The system detects objects based
on their size, profile, motion, etc.
However, an object may not be
detected depending on the sur-
rounding brightness and the motion,
posture, and angle of the detected
object, preventing the system from
operating properly. (
The illustration shows an image of
detectable objects.
■

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 sys-
tem, 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.

vides driving assistance to
reduce the driver’s burden.
However, there are limitations
to the assistance provided.
Read the following conditions
carefully. Do not overly rely on
this system and always drive
carefully.

driver is responsible for check-
ing the set speed.
●
Even when the system is func-
tioning normally, the condition
of the preceding vehicle as
detected by the system may dif-
fer from the condition observed
by the driver. Therefore, the
driver must always remain alert,
assess the danger of each situ-

WARNING
■
Cautions regarding the driv-
ing assist systems
Observe the following precau-
tions, as there are limitations to
the assistance provided by the
system. Failure to do so may
cause an accident resulting in
death or serious injury.
●
Assisting the driver to measure
following distance
The dynamic radar cruise control
with full-speed range is only
intended to help the driver in
determining the following distance
between the driver’s own vehicle
and a designated vehicle traveling
ahead. It is not a mechanism that
allows careless or inattentive driv-
ing, and it is not a system that can
assist the driver in low-visibility
conditions.
It is still necessary for driver to
pay close attention to the vehi-
cle’s surroundings.
●
Assisting the driver to judge
proper following distance
The dynamic radar cruise control
with full-speed range determines
whether the following distance
between the driver’s own vehicle
and a designated vehicle traveling
ahead is within a set range. It is
not capable of making any other
type of judgement. Therefore, it is
absolutely necessary for the
driver to remain vigilant and to
determine whether or not there is
a possibility of danger in any
given situation.
●
Assisting the driver to operate
the vehicle
The dynamic radar cruise control
with full-speed range does not
include functions which will pre-
vent or avoid collisions with vehi-
cles ahead of your vehicle.
Therefore, if there is ever any
possibility of danger, the driver
must take immediate and direct
control of the vehicle and act
appropriately in order to ensure
the safety of all involved.
■
Situations unsuitable for
dynamic radar cruise control
with full-speed range
Do not use dynamic radar cruise
control with full-speed range in
any of the following situations.
Doing so may result in inappropri-
ate speed control and could
cause an accident resulting in
death or serious injury.
●
Roads where there are pedes-
trians, cyclists, etc.
●
In heavy traffic
●
On roads with sharp bends
●
On winding roads
●
On slippery roads, such as
those covered with rain, ice or
snow
●
On steep downhills, or where
there are sudden changes
between sharp up and down
gradients
Vehicle speed may exceed the
set speed when driving down a
steep hill.

This mode employs a radar to detect the presence of vehicles up to
approximately 328 ft. (100 m) ahead, determines the current vehicle-
to-vehicle following distance, and operates to maintain a suitable fol-
lowing distance from the vehicle ahead. The desired vehicle-to-vehi-
cle distance can also be set by operating the vehicle-to-vehicle
distance switch.
When driving on downhill slopes, the vehicle-to-vehicle distance may
become shorter.

4-5. Using the driving support systems
Example of constant speed cruising
When there are no vehicles ahead
The vehicle travels at the speed set by the driver.
Example of deceleration cruising and follow-up cruising
When a preceding vehicle driving slower than the set speed
appears
When a vehicle is detected running ahead of you, the system automatically
decelerates your vehicle. When a greater reduction in vehicle speed is nec-
essary, the system applies the brakes (the stop lights will come on at this
time). The system will respond to changes in the speed of the vehicle
ahead in order to maintain the vehicle-to-vehicle distance set by the driver.
Approach warning warns you when the system cannot decelerate suffi-
ciently to prevent your vehicle from closing in on the vehicle ahead.
When the vehicle ahead of you stops, your vehicle will also stop (vehicle is
stopped by system control). After the vehicle ahead starts off, pressing the
“+RES” switch or depressing the accelerator pedal (start-off operation) will
resume follow-up cruising. If the start-off operation is not performed, system
control continues to keep your vehicle stopped.
When the turn signal lever is operated and your vehicle moves to an over-
taking lane while driving at 50 mph (80 km/h) or more, the vehicle will accel-
erate to help to overtake a passing vehicle.
The system’s identification of what is an overtaking lane may be deter-
mined solely based on the location of the steering wheel in the vehicle (left
side driver position versus right side driver position.) If the vehicle is driven
to a region where the overtaking lane is on a different side from where the
vehicle is normally driven, the vehicle may accelerate when the turn signal
lever is operated in the opposite direction to the overtaking lane (e.g., if the
driver normally operates the vehicle in a region where the overtaking lane is
to the right but then drives to a region where the overtaking lane is to the
left, the vehicle may accelerate when the right turn signal is activated).
Example of acceleration
When there are no longer any preceding vehicles driving slower
than the set speed
The system accelerates until the set speed is reached. The system then
returns to constant speed cruising.

The Blind Spot Monitor is a
system that has 2 functions:
The BSM (Blind Spot Moni-
tor) function
Assists the driver in making a
decision when changing lanes
The RCTA (Rear Cross
Traffic Alert) function
Assists the driver when back-
ing up
These functions use the
same sensors.
WARNING
■
Cautions regarding the use of
the BSM function
The driver is solely responsible for
safe driving. Always drive safely,
taking care to observe your sur-
roundings.
The BSM function is a supple-
mentary function which alerts the
driver that a vehicle is in a blind
spot of the outside rear view mir-
rors or is approaching rapidly from
behind into a blind spot. Do not
overly rely on the BSM function.
As the function cannot judge if it is
safe to change lanes, over reli-
ance could lead to an accident
resulting in death or serious
injury.
As the system may not function
correctly under certain condi-
tions, the driver’s own visual con-
firmation of safety is necessary.

play may be displayed abnor-
mally, or objects, such as a wall,
may not be detected.
●
A sensor is covered in any way.
●
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.
●
The vicinity of the vehicle is noisy
due to vehicle horns, motorcycle
engines, air brakes of large vehi-
cles, or other loud noises produc-
ing ultrasonic waves.
●
There is another vehicle equipped
with parking assist sensors in the
vicinity.
●
A sensor is coated with a sheet of
spray or heavy rain.
●
If a sensor is hit by a large amount
of water, such as when driving on
a flooded road.
●
If the vehicle is significantly tilted.
●
The vehicle is approaching a tall
or curved curb.
●
If objects draw too close to the
sensor.
■
Objects which may not be prop-
erly detected

Buzzer operation and dis-
tance to an object
A buzzer sounds when the sen-
sors are operating.
The buzzer beeps faster as
the vehicle approaches an
object. When the vehicle
comes within approximately
1.0 ft. (30 cm) of the object,
the buzzer sounds continu-
ously.
When 2 or more sensors
simultaneously detect a static
object, the buzzer sounds for
the nearest object. If one or
more objects come within
approximately 1.0 ft. (30 cm)
of the vehicle, the buzzer will
repeat a long tone, followed
by fast beeps.
Even when the sensors are
operating, the buzzer will be
muted in some situations.

skirt, etc., making their silhouette
obscure
• Pedestrians whose body is par-
tially hidden by an object, such as
a cart or umbrella
• Pedestrians which are obscured
by darkness, such as at night
●
In some situations, such as the
following, pedestrians may not be
detected by the rear camera
detection function, preventing the
function from operating properly:
• When backing up in inclement
weather (rain, snow, fog, etc.)
• When the rear camera is
obscured (dirt, snow, ice, etc. are
attached) or scratched
• When a very bright light, such as
the sun, or the headlights of
another vehicle, shines directly
into the rear camera
• When backing up in a place where
the surrounding brightness
changes suddenly, such as at the
entrance or exit of a garage or
underground parking lot
• When backing up in a dim envi-
ronment such as during dusk or in
an underground parking lot
• When the dedicated camera
cleaning washer is operating
●
Even though there are no pedes-
trians in the detection area, some

speed or backing up, such
as when parking. When the
system determines that the
possibility of a collision
with a detected object is
high, a warning operates to
urge the driver to take eva-
sive action. If the system
determines that the possi-
bility of a collision with a
detected object is extremely

WARNING
■
Limitations of the Parking
Support Brake 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 capabilities 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. Addition-
ally, even if the system has
stopped the vehicle, it is neces-
sary to depress the brake pedal
immediately as brake control
will be canceled after approxi-
mately 2 seconds.
●
Do not attempt to test the oper-
ation of the Parking Support
Brake system yourself.
Depending on the situations,
the system may not operate
properly, possibly leading to an
accident.

WARNING
●
Do not replace a sensor with a
part other than a genuine part.
●
Do not subject a sensor or its
surrounding area to a strong
impact.
●
Do not damage the sensors,
and always keep them clean.
●
If the area around a radar sen-
sor is subjected to an impact,
the system may not operate
properly due to a sensor mal-
function. Have the vehicle
inspected by your Toyota
dealer.
■
Handling the suspension
Do not modify the suspension, as
changes to the height or inclina-
tion of the vehicle may prevent
the sensors from detecting
objects correctly or cause the sys-
tem to not operate or operate
unnecessarily.
■
If the Parking Support Brake
function (static objects) oper-
ates unnecessarily, such as
at a railroad crossing
In the event that the Parking Sup-
port Brake function (static objects)
operates unnecessarily, such as
at a railroad crossing, brake con-
trol will be canceled after approxi-
mately 2 seconds, allowing you to
proceed forward and leave the
area, brake control can also be
canceled by depressing the brake
pedal. Depressing the accelera-
tor pedal after brake control is
canceled will allow you to proceed
forward and leave the area.
■
Notes when washing the vehi-
cle
Do not apply intensive bursts of
water or steam to the sensor
area.
Doing so may result in the sensor
malfunctioning.
●
When using a high pressure
washer to wash the vehicle, do
not spray the sensors directly,
as doing so may cause a sensor
to malfunction.
●
When using steam to clean the
vehicle, do not direct steam too
close to the sensors as doing so
may cause a sensor to malfunc-
tion.
■
When to disable the Parking
Support Brake
In the following situations, disable
the Parking Support Brake as the
system may operate even though
there is no possibility of a colli-
sion.

●
Vehicle surroundings
• 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
• The vehicle is approaching a tall
or curved curb.
• On an extremely bumpy road, on
an incline, on gravel, or on grass.
• The objects draw too close to the
sensor.
●
Other ultrasonic waves sources
• When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of other vehicles or
other devices which produce ultra-
sonic waves are near the vehicle
• If a sticker or an electronic compo-
nent, such as a backlit license
plate (especially fluorescent type),
fog lights, fender pole or wireless
antenna is installed near a sensor
●
Changes in the vehicle posture
• If the vehicle is significantly tilted
• If the front of the vehicle is raised
or lowered due to the carried load
• 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 bumper protector (an addi-
tional trim strip, etc.), hitch-
mounted bicycle carrier, or snow
plow

If a rear radar sensor detects a vehicle approaching from the
right or left at the rear of the vehicle and the system deter-
mines that the possibility of a collision is high, this function
will perform brake control to reduce the likelihood of an
impact with the approaching vehicle.
Examples of function operation
Types of sensors
WARNING
■
To ensure the Parking Sup-
port Brake (rear-crossing
vehicles) can operate prop-
erly
Observe the following precautions
regarding the rear radar sensors
(
P.301). Failure to do so may
cause a sensor to not operate
properly, and may cause an acci-
dent.

nated (
lowing conditions are met:
●
Hybrid system output restriction
control
• The Parking Support Brake is
enabled.
• The vehicle speed is approxi-
mately 9 mph (15 km/h) or less.
• Vehicles are approaching from the
right or left at the rear of the vehi-
cle at a traveling speed of more
than approximately 5 mph (8
km/h)
• The shift lever is in R.
• The Parking Support Brake deter-
mines that a stronger than normal
brake operation is necessary to
avoid a collision with an approach-
ing vehicle.
●
Brake control
• Hybrid system output restriction
control is operating
• The Parking Support Brake deter-
mines that an emergency brake
operation is necessary to avoid a
collision with an approaching vehi-
cle.
■
The Parking Support Brake
function (rear-crossing vehi-
cles) will stop operating when
The function will stop operating if
any of the following conditions are
met:
●
Hybrid system output restriction
control
• The Parking Support Brake is dis-
abled.
• The collision becomes avoidable
with normal brake operation.
• A vehicle is no longer approaching
from the right or left at the rear of
the vehicle.
●
Brake control
• The Parking Support Brake is dis-
abled.
• Approximately 2 seconds have
elapsed since the vehicle was
stopped by brake control.
• The brake pedal is depressed
after the vehicle is stopped by
brake control.
• A vehicle is no longer approaching
from the right or left at the rear of
the vehicle.
■
Re-enabling the Parking Sup-
port Brake (rear-crossing vehi-
cles)
■
Detection area of the Parking
Support Brake function (rear-
crossing vehicles)
The detection area of the Parking
Support Brake function (rear-cross-
ing vehicles) differs from the detec-
tion area of the RCTA function
(
P.306). Therefore, even if the
RCTA function detects a vehicle
and provides an alert, the Parking
Support Brake function (rear-cross-
ing vehicles) may not start operat-
ing.
WARNING
●
Do not modify, disassemble or
paint the sensors.
●
Do not replace a rear radar sen-
sor with a part other than a gen-
uine part.
●
Do not damage the rear radar
sensors, and always keep the
radar sensors and their sur-
rounding area on the bumper
clean.
●
If the area around a rear radar
sensor is subjected to an
impact, the system may not
operate properly due to a sen-
sor malfunction. Have the vehi-
cle inspected by your Toyota
dealer.
●
Observe the rear radar sensor
handling precautions. (
