■Intersection collision avoid-
ance support (crossing
vehicles)
At an intersection, etc., if the
system determines that the pos-
sibility of a collision with an
approaching vehicle or motorcy-
cle is high, the pre-collision
warning and pre-collision brak-
ing will operate. Depending on
the intersection, assistance may
not operate correctly.
■Acceleration Suppression
at Low Speed
When driving at a low speed, if
the accelerator pedal is strongly
depressed and the system
determines that there is a possi-
bility of a collision, EV system
output will be restrained or the
brakes will be applied weakly to
restrict acceleration. During operation, a buzzer will sound
and a warning indicator and
message will be displayed on
the multi-information display.
“Accelerator Pedal is
Pressed”
WARNING
■Pre-collision braking
●When the pre-collision braking
function is operating, a large
amount of braking force will be
applied.
●Pre-collision braking function is
not intended for remain
stopped. If the vehicle is
stopped by pre-collision brak-
ing function, the driver should
operate the brakes as neces-
sary.
●The pre-collision braking func-
tion may not operate if certain
operations are performed by the
driver. If the accelerator pedal is
being depressed strongly or the
steering wheel is being turned,
the system may determine that
the driver is taking evasive
action and possibly prevent the
pre-collision braking function
from operating.

Constant speed cruising:
When there are no vehicles ahead
The vehicle drives at the speed set by the driver.
If the set vehicle speed is exceeded while driving down a hill, the set vehicle
speed display will blin k and a buzzer will sound.
Deceleration and follow-up cruising
When a preceding vehicle driving slower than the set vehicle
speed is detected
When a vehicle is detected driving ahead of your vehicle, the v ehicle auto-
matically decelerates and if a greater reduction in vehicle spe ed is neces-
sary, the brakes are applied (the stop lights will come on at t his time). The
vehicle is controlled to maintai n the vehicle-to-vehicle distance set by the
driver, in accordance with changes in the speed of the precedin g vehicle. If
vehicle deceleration is not sufficient and the vehicle approaches the vehicle
ahead, the approach wa rning will sound.
Acceleration
When there are no longer any preceding vehicles driving slower
than the set vehicle speed
The vehicle accelerates until th e set vehicle speed is reached and then
resumes constant speed cruising.
Starting off: If a preceding vehi cle stops, the vehicle will also stop
(controlled stop). After the preceding vehicle starts off, pressing
the “RES” switch or depressing the accelerator pedal will resum e
follow-up cruising (start off operation). If a start off operat ion is not
performed, the controlled stop will continue.

●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
automatically.
The shift position may automatically
change to P. ( P.238)
●Situations in whic h some or all of
the functions of the system cannot
operate: P. 2 6 4
■Dynamic radar cruise control
system warning messages and
buzzers
For safe use: P.259
■Preceding vehicles that the sen-
sor may not detect correctly
In the following situations, depend-
ing on the conditions, if the system
cannot provide sufficient decelera-
tion or accelerati on is necessary,
operate the brake pedal or accelera-
tor pedal.
As the sensor may not be able to
correctly detect these types of vehi-
cles, the approach warning
(  P.294) may not operate.
●When a vehicle cuts in front of
your vehicle or changes lanes
away from your vehicle extremely
slowly or quickly
●When changing lanes
●When a preceding vehicle is driv-
ing at a low speed
●When a vehicle i s stopped in the
same lane as the vehicle
●When a motorcycle is traveling in
the same lane as the vehicle
■Conditions under which the
system may not operate cor-
rectly
In the following situations, operate
the brake pedal (or accelerator
pedal, depending on the situation)
as necessary.
As the sensor may not be able to
correctly detect a vehicle, the sys-
tem may not operate properly.
●When a preceding vehicle brakes
suddenly
●When changing lanes at low
speeds, such as in a traffic jam
In situations where the vehicle
approaches a preceding vehicle
and the system cannot provide
sufficient deceleration, such as
if a vehicle cuts in front of the
vehicle, a warning display will
flash and a buzzer will sound to
alert the driver. Depress the
brake pedal to ensure appropri-
ate vehicle-to-vehicle distance.
■Warnings may not occur
when
In the following situations, the
warning may not operate even
though the vehicle-to-vehicle
distance is short.
 When the preceding vehicle is
traveling at the same speed
or faster than your vehicle
 When the preceding vehicle is
traveling at an extremely low
speed
 Immediately after the vehicle
speed has been set

■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 car rier, or snow plow
●If the front of the v ehicle is raised
or lowered due to the carried load
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or
is malfunctioning
●When a tire chains, compact
spare tire or an emergency tire
puncture repair kit is used

PKSB (Parking Sup-
port Brake)*
The Parking Support Brake
system consists of the fol-
lowing functions that oper-
ate when driving at a low
speed or backing up, such
as when parking. When the
system determines that the
probability of a collision
with a detected object or
pedestrian is high, a warn-
ing operates to urge the
driver to take evasive
action. If the system deter-
mines that the possibility of
a collision with a detected
object or pedestrian is
extremely high, the brakes
are automatically applied to
help avoid the collision or
help reduce the impact of
the collision.

possible, the EV system output
will be restricted to restrain any
increase in the vehicle speed. (EV system output restriction
control: See figure 2.)
Additionally, if the accelerator
pedal continues to be
depressed, the brakes will be
applied automatically to reduce
the vehicle speed. (Brake con-
trol: See figure 3.)

●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.
■Detection range
The detection area of the moving
vehicles rear of the vehicle differs
from the detection area of the RCTA
function ( P.324). Therefore, even
if the RCTA function detects a vehi-
cle and provides an alert, the mov-
ing vehicles rear of the vehicle may
not start operating.
■RCTA buzzer
Regardless of weather the RCTA
function is on o r off, if the PKSB
(Parking Support Brake) system is
not disabled, when the brake control
operates, the buzze r will sounds to
alert the driver.

depressed or is depressed late.
Displays a message to urge the
Pedestrians Rear of
the Vehicle*
If the rear camera sensor
detects a pedestrian behind
the vehicle while backing
up and the system deter-
mines that the possibility of
colliding with the detected
pedestrian is high, a buzzer
will sound. If the system
determines that the possi-
bility of colliding with the
detected pedestrian is
extremely high, the brakes
will be applied automati-
cally to help reduce the
impact of the collision.
