• When there is a wall, etc. in front of a stopped vehicle
• When there is another object near the vehicle
• When a vehicle, etc. is stopped in the lateral direction
• With vehicles that are backing up or with oncoming vehicles, etc.
• When the size and height of an obstacle is smaller than the limitations
of the stereo cameras’ recognition capability
- With small animals or children, etc.
- With pedestrians who are sitting or lying down
• When the detected
object is a fence, wall or
shutter, etc.
• When there is a wall or
door made of glass or a
mirror in front
• When the vehicle in front
suddenly swerves,
accelerates, or deceler-
ates.
• When a vehicle, motor-
cycle, bicycle or pedes-
trian cuts in from the
side or jumps out sud-
denly
• When you suddenly
change lanes and your
vehicle is immediately
behind an obstacle
• When there is a vehicle, motorbike, bicycle or pedestrian in a location
extremely close to your vehicle
• When the speed difference between your vehicle and an obstacle is 4
MPH (5 km/h) or less (As braking is performed once the obstacle is in
close proximity to your vehicle, depending on the shape and size of the
obstacle, there may be some cases when the obstacle is outside the
range of the cameras’ field of vision.)
• When driving on sharp curves, steep uphill grades or steep downhill
grades
• When driving on a bumpy or unpaved road
• When passing through the entrance or exit of a tunnel
lxFor your safety, do not test the Pre-Collision Braking System function by
yourself. There is a possibility that the vehicle will not stop or the function
will not work during the test and this may cause an unexpected accident.
xThe system may not operate correctly under the conditions listed below.
When these conditions occur, turn off the Pre-Collision Braking System.
- The tire pressure is not correct.*
- A temporary spare tire is installed.*
- Tires that are worn or have large variations in wear conditions.*
- Tires other than those of the designated size are installed.*
- Flat tires are repaired using the flat tire repair kit.
- The suspension has been modified.
- Tire chains are installed.
- The headlights are dirty or are not aligned correctly. (Objects are not cor-
rectly illuminated and are difficult to detect.)
- Vehicle operation has become compromised due to an accident or mal-
function.
- The brake warning light is illuminated.
- The vehicle is tilted due to a heavy cargo load.
- The maximum number of occupants and/or the gross vehicle weight rat-
ing has been exceeded.
*The wheels and tires have functions that are critically important. Be sure
to use the correct parts. For details, refer to the Owner’s Manual for your
vehicle.

CAUTION
xIn the following situations, turn off the Pre-Collision Braking System. Other-
wise the Pre-Collision Braking System may activate unexpectedly.
- When the vehicle is being towed
- When loading the vehicle onto a carrier
- When a chassis dynamometer, free-rollers or similar equipment is used
- When a mechanic lifts up the vehicle, starts the engine and spins the
wheels freely
- When passing hanging banners, flags or branches, or when thick/tall
vegetation is contacting the vehicle
- When using a drive-through
car wash
xThe Pre-Collision Braking System may activate in the following situations.
Therefore concentrate on safe driving.
- When passing through an automatic gate (opening and shutting)
- When driving close to the vehicle in front
- When driving in a location where the grade of the road changes rapidly
- When passing through clouds of steam or smoke
- When the exhaust gas emitted by the vehicle in front is clearly visible in cold
weather, etc.

- When there is an obstacle on
a curve or intersection
- When narrowly passing a
vehicle or an object
- When stopping very close to
a wall or a vehicle in front
xIf there is cargo or installed
accessories, etc. that are pro-
truding over the edge of the
front bumper, the vehicle’s
length will increase and the
system may not be able to pre-
vent a collision.
xIf the driver operates the brake
pedal during automatic braking, the pedal may feel stiff; however, this is nor-
mal. By depressing the brake pedal further you can apply more braking force.
NOTE
xWhen the Pre-Collision Braking System OFF indicator light illuminates, this
function will not operate.
* Refer to page 51.
xSome unusual noises may be audible during automatic braking. This is
caused by the braking control and is normal.

■Detection of pedestrians
The EyeSight system can also detect
pedestrians. The EyeSight system detects
pedestrians from their size, shape and
movement. The system detects a pedestrian
when the contour of the head and shoulders
are clear and the left/right balance is
symmetrical.
WARNING
The EyeSight system’s Pre-Collision Braking function also treats pedestrians
as obstacles. However, depending on the conditions, there may be cases
when the system cannot detect a pedestrian. In the following conditions, the
possibility that the system may not be able to detect a pedestrian as an object
is particularly high.
xWhen pedestrians are walking in a group
xWhen a pedestrian is next to a wall or other obstacle
xWhen a pedestrian is using an umbrella
xWhen a pedestrian is wearing clothes that are a similar color to the sur-
rounding environment
xWhen a pedestrian is carrying bulky luggage
xWhen a pedestrian is bent over, crouching down or lying down
xWhen a pedestrian is in a dark location
xWhen a pedestrian suddenly jumps out into the field of view

Pre-Collision Braking System
49
When there is an obstacle in the forward direction during driving, the system activates in the
following sequence in order to warn the driver, activate braking control, and active the brake
lights.
(1) Following Distance Warning:
When the system determines that there is a risk of collision, a buzzer sounds repeated short
beeps and the indicators on the meter display and the multi function display illuminate to
warn the driver.
The Following Distance Warning operates when Adaptive Cruise Control is not set.
When the driver depresses the brake pedal to decelerate and achieves a suitable following
distance, the warning is canceled.
(2) First Braking and Warning:
When the system determines that there is a high risk of collision with an obstacle in front, a
buzzer sounds repeated short beeps and the indicators on the meter display and the multi
function display illuminate to warn the driver, and braking control is activated. If the system
determines that the amount of evasive action (braking, steering, etc.) taken by the driver
has reduced the risk of collision, braking activation is canceled.
(3) Second Braking and Warning:
If the system then determines that the risk of collision is extremely high, the buzzer changes
to a continuous beeping sound and stronger braking control is activated. If, despite any eva-
sive action taken by the driver, the system subsequently determines that a collision is
unavoidable, braking control is continued.
When the vehicle stops, a buzzer sounds three short beeps and a single long beep. The
automatic braking function is cancelled approximately 2 seconds after the vehicle stops and
the vehicle starts creeping forward gradually.

Pre-Collision Braking System
50
When the Pre-Collision Braking System is activated utilizing first braking or second braking
(when the system determines that there is a high risk of collision with an obstacle in front), if
the driver depresses the brake pedal, the system determines that this is emergency braking
and activates braking assist automatically.
CAUTION
The Pre-Collision Braking System will not activate when the EyeSight warn-
ing light ( ) is illuminated or flashing, or when the EyeSight temporarily
stops.
NOTE
Neither primary Pre-Collision Braking nor secondary Pre-Collision Braking
will operate in the following conditions.
xWhen the vehicle speed is approximately 1 MPH (1 km/h) or lower, or
approximately 100 MPH (160 km/h) or higher.
xWhen the Vehicle Dynamics Control is functioning.
Pre-Collision Braking Assist operation
CAUTION
If the driver depresses the brake pedal manually while following distance
warning is activated, the Pre-Collision Braking Assist will not work. (The
vehicle decelerates with the normal braking force operated by the driver.)
NOTE
xPre-Collision Braking Assist function does not operate when the vehicle
speed is approximately 7 MPH (10 km/h) or less or 100 MPH (160 km/h) or
more.
xFor information about the braking assist function, refer to the Owner’s
Manual for your vehicle.

Pre-Collision Braking System

When pressing and holding the Pre-Collision
Braking System OFF switch for approximately
2 seconds (or longer), a single short beep will
sound and the Pre-Collision Braking System
(including Pre-Collision Brake Assist) will turn
off. When this control is turned off, the Pre-
Collision Braking System OFF indicator light
on the instrument panel illuminates. To turn
the control back on, press and hold the Pre-
Collision Braking System OFF switch for
approximately 2 seconds or longer again.
When this control is turned on, the Pre-
Collision Braking System OFF indicator light
will turn off.
■Pre-Collision Braking System OFF indicator light
This indicator light illuminates when the
ignition switch is turned to the ON position,
and remains illuminated for approximately 7
seconds after the engine starts. It turns on
when the Pre-Collision Braking System is
turned off.
It also illuminates under the following
conditions.
xWhen the VDC OFF switch is pressed and
VDC is canceled
xWhen the EyeSight system has a
malfunction
* Refer to page 76.
xWhen the EyeSight system has stopped
temporarily
* Refer to page 77.
Turning off the Pre-Collision Braking System
NOTE
xWhen the Pre-Collision Braking System is turned off, the Pre-Collision
Throttle Management Control function is also turned off.
xEven when the Pre-Collision Braking System is turned off, if the ignition
switch is turned off and the engine is then restarted, the Pre-Collision
Braking System will be turned on. The system default setting when the
vehicle is restarted in “ON”.

Pre-Collision Throttle Management
When an obstacle is detected in front of the
vehicle, and the vehicle is stopped or travel-
ling very slowly, if the system determines that
the accelerator pedal has been depressed by
more than the necessary amount (due to
driver error), it greatly restricts engine output
and ensures that vehicle forward movement is
slower than normal in order to give the driver
additional time to brake or react.
During system operation, a buzzer will sound several short beeps and the lead vehicle indi-
cator and the following distance setting indicator will blink in the meter display. Also, a pop-
up screen will be displayed in the multi function display.
This function only activates when the transmission select lever is in the or position.

WARNING
Do not rely excessively on Pre-Collision Throttle Management. Pre-
Collision Throttle Management is not designed to help you avoid
collisions in many situations. Always check the selector lever and pedal
positions as well as the surrounding environment before starting and
operating the vehicle. Relying only on Pre-Collision Throttle
Management could result in an accident.
xPre-Collision Throttle Management is not designed to maintain the vehicle
in a stopped condition.
